GridView Unable to Update the data into database - c#

I am trying to update the record by using gridview by using n tier applications. My insert and delete is working but when I tried to update the record from gridview update button it not updating the record and retrieving old record.
Here is the store procedure
CREATE PROCEDURE [dbo].[UpdateJob]
(
#Job_ID int ,
#Title [varchar](50) ,
#Location [varchar](50),
#Exprience [varchar](500),
#Type_Contract [varchar](50) ,
#Posted_Date [varchar](50),
#Salary [varchar](50)
)
AS
update Job_Profile
set
#Title = #Title,
#Location = #Location,
#Exprience = #Exprience,
#Type_Contract = #Type_Contract,
#Posted_Date = #Posted_Date,
#Salary = #Salary
where
#Job_ID = #Job_ID
RETURN
GO
Here is my methods .
public void Job_update(int Job_ID, string title, string location, string exprience, string type_Contract, string posted_Date, string salary)
{
SqlConnection con = new SqlConnection(#"Data Source=NIRJOR\SQLEXPRESS;Initial Catalog=StudentJobPortal;Integrated Security=True");
SqlCommand cmd = new SqlCommand("UpdateJob", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("Job_Id", Job_ID);
cmd.Parameters.AddWithValue("Title", title);
cmd.Parameters.AddWithValue("Location", location);
cmd.Parameters.AddWithValue("Exprience", exprience);
cmd.Parameters.AddWithValue("Type_Contract", type_Contract);
cmd.Parameters.AddWithValue("Posted_Date", posted_Date);
cmd.Parameters.AddWithValue("Salary", salary);
con.Open();
int i = cmd.ExecuteNonQuery();
con.Close();
}

I'd say the problem is in your stored procedure:
update Job_Profile
set
#Title = #Title,
#Location = #Location,
#Exprience = #Exprience,
#Type_Contract = #Type_Contract,
#Posted_Date = #Posted_Date,
#Salary = #Salary
where
#Job_ID = #Job_ID
RETURN
All this query does, if it's even syntactically valid, is update the input parameters to the same value they already are
An update command that updates a table column(s) with values from parameters would look like:
update Job_Profile
set
Title = #Title,
Location = #Location,
Exprience = #Exprience,
Type_Contract = #Type_Contract,
Posted_Date = #Posted_Date,
Salary = #Salary
where
Job_ID = #Job_ID
RETURN
The things on the left hand side of the = need to be column names. If they start with an # then they aren't column names. # is used at the start of variable names
UPDATE tablename
SET columnName = #variableName
WHERE ...
When you face a problem like this break it down into steps - call this stored procedure with SSMS. It either works or it doesn't. If it works then the problem is in C# code. If it doesn't the n the problem is in SP code.. this is a basic debugging; narrow down the cause of the problem so you're sure where it is occurring

OnRowCommand is triggered, OnRowEditing not firing on my gridview

I have a gridview like below:
<asp:GridView ID="gvitems" runat="server" AutoGenerateColumns="false" CssClass="GridStyle" AllowSorting="true" OnSorting="OnSorting" DataKeyNames="Id" OnRowCommand="gv_RowCommand"
OnRowEditing="gv_RowEditing" OnRowUpdating="gv_RowUpdating" OnRowCancelingEdit="gv_RowCancelEdit" >
<Columns>
<asp:buttonfield buttontype="Link"
commandname="View"
text="View"/>
<asp:TemplateField>
<ItemTemplate>
<asp:Button runat="server" Text="Edit" />
</ItemTemplate>
<EditItemTemplate>
<asp:Button runat="server" Text="Update" />
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Next Steps">
<ItemTemplate>
<asp:Label runat="server" ID="lblNextSteps" Text='<%# Eval("NextSteps")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="txtNextSteps" Text='<%# Eval("NextSteps")%>'></asp:TextBox>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox runat="server" ID="txtNextStepsFooter"></asp:TextBox>
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And in the backend, this is how i fill it with data:
DataSet dataSet = null;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.BindGrid_SubmittedProjects();
}
}
private void BindGrid_SubmittedProjects(string sortExpression = null)
{
using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ProjectsDataBase"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand("ViewProjects", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#UserName", SqlDbType.VarChar).Value = "myusername";
cmd.Connection = con;
using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
{
dataSet = new DataSet();
sda.Fill(dataSet, "Project");
}
gvitems.DataSource = dataSet.Tables[0].DefaultView;
gvitems.DataBind();
}
}
}
When I click on the "View" hyperlink on each row, it works, so OnRowCommand function below is triggered.
protected void gv_RowCommand(Object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "View")
{
//my work
}
}
However, when I click on "Edit" button, nothing is happening, OnRowEditing is not being triggered.
protected void gv_RowEditing(Object sender, GridViewEditEventArgs e)
{
gvitems.EditIndex = e.NewEditIndex;
this.BindGrid_SubmittedProjects();
}
protected void gv_RowUpdating(Object sender, GridViewUpdateEventArgs e)
{
//my update query.
}
I could not see what I am doing wrong. Tried many things I've found over online but none worked. Any help would be so appreciated.
Regards.

Using LinkButton instead of regular button fixed the issue.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Edit" runat="server" CommandName="Edit" />
<asp:LinkButton Text="Delete" runat="server" CommandName="Delete" />
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton Text="Update" runat="server" CommandName="Update" />
<asp:LinkButton Text="Cancel" runat="server" CommandName="Cancel" />
</EditItemTemplate>
</asp:TemplateField>

unable to update database through gridview in c#

I am creating a system in which i want to edit several records from the database through administrator using a data grid view:
Table Schema used in this is
CREATE TABLE [dbo].[tbl_Employee] (
[ID] INT NOT NULL,
[Name] VARCHAR (50) NULL,
[City] VARCHAR (50) NULL,
PRIMARY KEY CLUSTERED ([ID] ASC)
);
I have added Add OnRowEditing, OnRowUpdating and OnRowCancelingEdit events to the GridView.
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="6" OnRowCancelingEdit="GridView1_RowCancelingEdit"

</ItemTemplate>
<EditItemTemplate>

<asp:Button ID="btn_Cancel" runat="server" Text="Cancel" CommandName="Cancel"/>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>

</asp:TemplateField>
</Columns>
<HeaderStyle BackColor="#663300" ForeColor="#ffffff"/>
<RowStyle BackColor="#e7ceb6"/>

And the c# code
using System;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{

adapt.Fill(dt);
if(dt.Rows.Count>0)
{
GridView1.DataSource = dt;
GridView1.DataBind();
}
con.Close();
}
protected void GridView1_RowEditing(object sender, System.Web.UI.WebControls.GridViewEditEventArgs e)
{
//NewEditIndex property used to determine the index of the row being edited.
GridView1.EditIndex = e.NewEditIndex;
ShowData();
}
protected void GridView1_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
{
//Finding the controls from Gridview for the row which is going to update
Label id=GridView1.Rows[e.RowIndex].FindControl("lbl_ID") as Label;
TextBox name = GridView1.Rows[e.RowIndex].FindControl("txt_Name") as TextBox;
TextBox city = GridView1.Rows[e.RowIndex].FindControl("txt_City") as TextBox;
con = new SqlConnection(cs);
con.Open();
//updating the record
SqlCommand cmd = new SqlCommand("Update tbl_Employee set Name='"+name.Text+"',City='"+city.Text+"' where ID="+Convert.ToInt32(id.Text),con);

//Call ShowData method for displaying updated data
ShowData();
}

{
//Setting the EditIndex property to -1 to cancel the Edit mode in Gridview
GridView1.EditIndex = -1;
ShowData();
}
}
The code is not showing any error but the database is not getting updated.
Where am i going wrong?

DateTime search problems ASP.NET

I have a database that stores lottery form submissions from users. One of the columns is a DateTime column that is populated with the current DateTime every time someone submits a form. I want to be able to search by the DateTime column so I can pull up all the forms entered on a particular day.
I'm not getting any errors when I perform the search, just my custom message that "No results matching that search criteria". I've tried disabling the jquery datepicker and tried copying and pasting the exact DateTime field from the DB into the search box and still nothing. Obviously I'm missing something but I can't figure out what. Any help is much appreciated.

In SQL, you state that you are storing the data as a DateTime. This means you are getting the date and the time. Of course the time includes hours, minutes, seconds, etc...
In you query you need to CAST your DateTime to a Date in order to remove the time from it.

Here is my code behind the aspx page
protected void btnEdit_Click(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)sender;
GridViewRow row = (GridViewRow)btn.NamingContainer;
int i = Convert.ToInt32(row.RowIndex);
_connString = ConfigurationManager.AppSettings["connString"];
using (SqlConnection conn = new SqlConnection(_connString))
{
conn.Open();
SqlCommand cmd = new SqlCommand("update ref_registration_company_user
set ind_active=1 where id_company_user=id_company_user", conn);
cmd.ExecuteNonQuery();
conn.Close();
}
}
Here is Design View :
I just want that only selected row should be affected in database.
I will be thank full for help.

you need to set the id_company_user value in your sql statement. use parameters as below.
SqlCommand cmd = new SqlCommand("update ref_registration_company_user set ind_active=1 where id_company_user=#id_company_user", conn);
cmd.Parameters.AddWithValue("#id_company_user", id);
you need to get current row id_company_user value check below SO question and answer, you can use
OnRowCommand of GridView and CommandArgument property
GridView: Get datakey of the row on button click
<asp:GridView ID="grdCompanyUsers" runat="server" DataKeyNames="id_company_user,nm_company_username" AutoGenerateColumns="false" GridLines="None" CssClass="grid" AlternatingRowStyle-BackColor="#DDE0EF" OnRowDataBound="grdCompanyUsers_DataBound"
OnRowCommand="myGridView_RowCommand">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="btnEdit" runat="server" Font-Underline="false" CommandArgument='<%#Eval ("id_company_user")%>' CommandName="Edit">Edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
code-behind:
protected void myGridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
var id= int.Parse(e.CommandArgument);
_connString = ConfigurationManager.AppSettings["connString"];
using (SqlConnection conn = new SqlConnection(_connString))
{
conn.Open();
using(SqlCommand cmd = new SqlCommand("update ref_registration_company_user set ind_active=1 where id_company_user=id_company_user", conn))
{
cmd.Parameters.AddWithValue("#id_company_user", id);
cmd.ExecuteNonQuery();
}
}
}

Can you please check once your update query where clause,

Check the sqlDataSource control for this problem, you can add the select and update command for populate and update rows your GridView on there.
Maybe this example could be you useful

Set selected value of dropdown list in Gridview.RowEditing

I am doing insert/update and delete in gridview. For that I am using ItemTemplate which contains labels to show the values. But when the gridview is in edit mode, the dropdown lists comes in place of that labels. I want to set the selected values of drop down lists to the values of labels. My drop down lists dont have datasource. I am binding dropdown list from 0 to 99. Below is the code for my edit method.
protected void grdUsedCatheters_RowEditing(object sender, GridViewEditEventArgs e)
{
try
{
grdUsedCatheters.EditIndex = e.NewEditIndex;
BindCatheterGrid();
DropDownList ddlFrom = (DropDownList)grdUsedCatheters.Rows[e.NewEditIndex].FindControl("ddFrom");
DropDownList ddlTo = (DropDownList)grdUsedCatheters.Rows[e.NewEditIndex].FindControl("ddTo");
BindDropDowns(ddlFrom);
BindDropDowns(ddlTo);
}
catch (Exception ex)
{
if (ex.HelpLink == null)
lblMessage.Text = ex.Message;
else
lblMessage.Text = ex.HelpLink;
lblMessage.CssClass = "ERROR";
}
private void BindDropDowns(DropDownList ddl)
{
for (int i = 0; i <= 99; i++)
ddl.Items.Add(i.ToString());
}
below is the part of markup of my gridview
<asp:TemplateField HeaderText="Cine Run">
<ItemTemplate>
From: <asp:Label ID="lblFrom" runat="server" ><%# Eval("CineRunFrom")%></asp:Label>
To: <asp:Label ID="lblTo" runat="server"><%# Eval("CineRunTo")%></asp:Label>
</ItemTemplate>
<EditItemTemplate>
From: <asp:DropDownList ID="ddFrom" runat="server" Width="50px">
</asp:DropDownList>
To: <asp:DropDownList ID="ddTo" runat="server" Width="50px">
</asp:DropDownList>
</EditItemTemplate>
<FooterTemplate>
From: <asp:DropDownList ID="ddFromF" runat="server" Width="50px"> </asp:DropDownList>
To: <asp:DropDownList ID="ddToF" runat="server" Width="50px"> </asp:DropDownList>
</FooterTemplate>
</asp:TemplateField>
}

Retrieve the values of label's before setting grdUsedCatheters.EditIndex = e.NewEditIndex and calling BindCatheterGrid() method and then after populating the DropDownLists set their selected value accordingly. Like this:
protected void grdUsedCatheters_RowEditing(object sender, GridViewEditEventArgs e)
{
try
{
Label lblFrom = (Label)grdUsedCatheters.Rows[e.NewEditIndex].FindControl("lblFrom"); //lblFrom is the ID of label
grdUsedCatheters.EditIndex = e.NewEditIndex;
BindCatheterGrid();
DropDownList ddlFrom = (DropDownList)grdUsedCatheters.Rows[e.NewEditIndex].FindControl("ddFrom");
DropDownList ddlTo = (DropDownList)grdUsedCatheters.Rows[e.NewEditIndex].FindControl("ddTo");
BindDropDowns(ddlFrom);
BindDropDowns(ddlTo);
ddlFrom.Text = lblFrom.Text;
}
catch (Exception ex)
{
if (ex.HelpLink == null)
lblMessage.Text = ex.Message;
else
lblMessage.Text = ex.HelpLink;
lblMessage.CssClass = "ERROR";
}
}
Edit
and also change your gridview markup like this:
<asp:TemplateField HeaderText="Cine Run">
<ItemTemplate>
From: <asp:Label ID="lblFrom" runat="server" Text='<%# Eval("CineRunFrom")%>' />
To: <asp:Label ID="lblTo" runat="server" Text='<%# Eval("CineRunTo")%>' />
</ItemTemplate>
...

I think this example will work for you.
First you put hidden field in EditItemTemplate where u have put the Dropdownlist.
Set the value of hidden field as you set the value of label in ItemTemplate
See my code:
<asp:GridView runat="server" ID="gridExample" OnRowEditing="gridExample_RowEditing"
AutoGenerateEditButton="True" AutoGenerateColumns ="false" OnRowCancelingEdit ="gridExample_RowCancelingEdit" >
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lblID" Text='<%# Eval("ID") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList runat="server" ID="drpName">
</asp:DropDownList>
<asp:HiddenField runat ="server" ID ="hdnId" Value ='<%# Eval("ID") %>' />
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lblName" Text='<%# Eval("Name") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate >
<asp:TextBox runat ="server" ID="txtName" Text ='<%# Eval("Name") %>' ></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void gridExample_RowEditing(object sender, GridViewEditEventArgs e)
{
gridExample.EditIndex = e.NewEditIndex;
BindGrid();
DropDownList dl=new DropDownList ();
dl = (DropDownList)gridExample.Rows[gridExample.EditIndex].FindControl("drpName");
FillDrops(dl);
HiddenField hdnId = new HiddenField();
hdnId = (HiddenField)gridExample.Rows[gridExample.EditIndex].FindControl("hdnId");
dl.Text = hdnId.Value;
}
