insert/update in GridView

insert/update in GridView - c#

I'm using asp.net with C# and SQL server 2008 r2. I have Gridview to insert, update, and delete some data of employees.
I have two problems:
With the insert I got this error
System.NullReferenceException: Object reference not set to an instance of an object.
When I click on edit nothing happen. I thing it because of index in e.CommandName == "EditRow" but I'm not sure. I believe I'm going to get the same problem when else if e.CommandName == "UpdateRow"
Delete is working fine.

To make gridview in edit mode you need to add event rowediting
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
bindgrid(); // your GV bind function
}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
bindgrid();// your GV bind function
}

How do I get my stored procedure to work inside my Visual Studio project?

I am using Visual Studio 2017 (Windows 10) and I have made an ASP.NET empty web application in C#.
In SQL Server Express, I wrote a stored procedure for edit, update and delete for my grid view. Earlier I have added strings for the edit, update and delete operations.
But for security reasons I now want a stored procedure to administrate my data. The stored procedure works correctly when I execute it in SSMS and all I have done so far is implemented the stored procedure into my code. But when I execute the code none changes can be made what so ever.
So the questions is how I should modify my code from here in Visual Studio in C# for the stored procedure to work when I execute my project?

I need my code to Add and bind data to the gridview in asp web form

I don't know what's wrong with the code i've tried to search for possible reasons but haven't figured out yet what's the problem actually.Now the issue is that my web form contains a gridview in which i've place a footer row which will allow the user to add the data and that data gets added to the database and gets binded to the gridview after clicking on the insert link button,But the problem comes when i fill the data and when press link button insert it adds the data twice in gridview and in database too everytime.Below is my whole code which is performing CRUD operation on gridview:

you just need to add Convert.ToDateTime() , then your query'll definately work.
but, your doing it in a wrong way.
use Parameterized Query,
A parameterized query is a query in which placeholders are used for
parameters and the parameter values are supplied at execution time.
The most important reason to use parameterized queries is to avoid SQL
injection attacks
In your case, you need to change the insert query:
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (" + cc + "," + cv + "," + cs + "," + cr + "," + usag + "," + isecure + "," + Convert.ToDateTime(ds) + "," + Convert.ToDateTime(de) + ") ";
Or, You can change the ds and dt variable datatype
CultureInfo provider = CultureInfo.InvariantCulture;
string format="dd/mm/yyyy";//define your datetime format here
DateTime ds=DateTime.ParseExact(textbox1.Text, format, provider);
DateTime de=DateTime.ParseExact(textbox2.Text, format, provider);
and then pass it to the query,like
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (" + cc + "," + cv + "," + cs + "," + cr + "," + usag + "," + isecure + "," +ds + "," + de + ") ";
Edit 2:
private void add(int cc, int cv, int cs, int cr,int usag,int isecure, string ds, string de)
{
using (MySqlConnection cn = new MySqlConnection(connectionstring))
{
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (#cc,#cv,#cs,#cr,#usag,#isecure,#ds,#de) ";
MySqlCommand cmd = new MySqlCommand(query, cn);
cmd .Parameters.Add("#cc",MySqlDbType.Int).Value=cc;
cmd .Parameters.Add("#cv",MySqlDbType.Int).Value=cv;
cmd .Parameters.Add("#cs",MySqlDbType.Int).Value=cs;
cmd .Parameters.Add("#cr",MySqlDbType.Int).Value=cr;
cmd .Parameters.Add("#usag",MySqlDbType.Int).Value=usag;
cmd .Parameters.Add("#isecure",MySqlDbType.Int).Value=isecure;
cmd .Parameters.Add("#ds",MySqlDbType.Date).Value=ds;
cmd .Parameters.Add("#de",MySqlDbType.Date).Value=de;
cn.Open();
cmd.ExecuteNonQuery();
}
}

Please consider using parametric queries & Convert.toDateTime().
private void add(int cc, int cv, int cs, int cr,int usag,int isecure, string ds, string de)
{
using (MySqlConnection cn = new MySqlConnection(connectionstring))
{
using (var sqlcmd = new SqlCommand())
{
sqlcmd.Connection = cn;
sqlcmd.CommandText = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (#codeCust,
#codeVendor, #codeService, #codeRegion, #Usages, #isSecure, #dateStart, #dateEnd)")
sqlcmd.Parameters.AddWithValue("#codeCust", cc);
sqlcmd.Parameters.AddWithValue("#codeVendor", cv);
sqlcmd.Parameters.AddWithValue("#codeService", cs);
sqlcmd.Parameters.AddWithValue("#codeRegion", cr);
sqlcmd.Parameters.AddWithValue("#Usages", usag);
sqlcmd.Parameters.AddWithValue("#isSecure", isecure);
sqlcmd.Parameters.AddWithValue("#dateStart", Convert.ToDateTime(ds));
sqlcmd.Parameters.AddWithValue("#dateEnd", Convert.ToDateTime(de));
cn.open();
sqlcmd.ExecuteNonQuery();
}
}
}

You have to specify date format.
Sample code:
str_to_date(de,"%d/%m/%Y")
str_to_date is mysql function. Kindly refer MySQL documentation.
https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html

How to remove row from gridview on row command event?
Use gridview rowcommand as Rajpurohit said, then use gvYourGrid.DeleteRow(index);

Datagrid with DropDownList columns in edit mode

I have an editable DataGrid with an EditCommandColumn. Initially the DataGrid is showing the correct values pulled from the database. The problem is that when a row goes into edit mode the columns with DropDownLists show the first value in the list and not the correct value. What would cause this and how do I fix it?

First, add DataValueField to your DropDownLists:
<asp:dropdownlist
ID="Dropdownlist1"
DataValueField="kundertype"
...
<asp:dropdownlist
ID="Dropdownlist2"
DataValueField="anrede"
...
Second, add an onitemdatabound event to your DataGrid:
<asp:DataGrid
onitemdatabound="DataGrid1_ItemDataBound"
...
Third, add this method to handle the ItemDataBound event:
protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.EditItem)
{
DropDownList dropDownList1 = (DropDownList)e.Item.FindControl("Dropdownlist1");
DataRowView dataItem1 = (DataRowView)e.Item.DataItem;
dropDownList1.SelectedValue = (string)dataItem1.Row["kundertype"];
DropDownList dropDownList2 = (DropDownList)e.Item.FindControl("Dropdownlist2");
DataRowView dataItem2 = (DataRowView)e.Item.DataItem;
dropDownList2.SelectedValue = (string)dataItem2.Row["anrede"];
}
}
Also note that the DataGrid control has been succeeded by the GridView. It might not be worth it for you to change, but you can check out the comparison here.
