Set the first value as NULL value to DropDownMenu C#

When I run application dropdown menu's value are always set to 0 and displaying result in Report.
I want to modify these to add text in DropDownMenu and when user is not selected anything it should return all data, if user select value from dropdown it should return value which user selected.
First DropDownMenu
public void FillOrgUnit()
{
using (SqlConnection conn = new SqlConnection(#"Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=DesignSaoOsig1;Integrated Security=True"))
{
string com = "SELECT DISTINCT OrgUnitID FROM tblZaposleni_AD ORDER BY OrgUnitID ASC";
SqlDataAdapter adpt = new SqlDataAdapter(com, conn);
DataTable dt = new DataTable();
adpt.Fill(dt);
ddlOrgUnit.DataSource = dt;
ddlOrgUnit.DataTextField = "OrgUnitID";
ddlOrgUnit.DataValueField = "OrgUnitID";
ddlOrgUnit.DataBind();
ddlOrgUnit.Items.Insert(0, new ListItem("-- Izaberi Org Jedinicu --", "NULL"));
}
}
Second dropdown menu:
public void FillStatus()
{
using (SqlConnection conn = new SqlConnection(#"Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=DesignSaoOsig1;Integrated Security=True"))
{
string com = "SELECT DISTINCT Status FROM tblZaposleni_AD";
SqlDataAdapter adpt = new SqlDataAdapter(com, conn);
DataTable dt = new DataTable();
adpt.Fill(dt);
ddlStatus.DataSource = dt;
ddlStatus.DataTextField = "Status";
ddlStatus.DataValueField = "Status";
ddlStatus.DataBind();
ddlStatus.Items.Insert(0, new ListItem("-- Izaberi Status --", "NULL"));
}
}
enter image description here

<p class="auto-style1">

Page_Load where I call FillStatus and FillOrgUnt metod
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string path = #"\Reports\";
CustomReportStorageWebExtension reportsStorage = new CustomReportStorageWebExtension(path);
ddlReportName.DataSource = reportsStorage.GetUrls();
ddlReportName.DataBind();
//Call function for populate cb
FillStatus();
FillOrgUnit();
}
else
{
XtraReport reportToOpen = null;
switch (ddlReportName.SelectedValue)
{
case "Zaposleni 1":
reportToOpen = new ZaposleniSaoOsig1();
break;
case "Zaposleni 2":
reportToOpen = new ZaposleniSaoOsig2();
break;
case "Zaposleni 3":
reportToOpen = new ZaposleniSaoOsig3();
break;
}
GetReports(reportToOpen);
ASPxWebDocumentViewer1.OpenReport(reportToOpen);
}
}
Main function which filters Status and OrgUnit
private void GetReports(XtraReport report)
{
try
{
string connString = #"Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=DesignSaoOsig1;Integrated Security=True";
SqlConnection conn = new SqlConnection(connString);
string strproc = "TestReport";
using (SqlDataAdapter sda = new SqlDataAdapter(strproc, connString))
{
DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
sda.SelectCommand.Parameters.Add("#Status", SqlDbType.Bit).Value = ddlStatus.SelectedValue == "1" ? true : false;
sda.SelectCommand.Parameters.Add("#OrgJed", SqlDbType.Int).Value = ddlOrgUnit.SelectedValue;
sda.Fill(ds);
string[] arrvalues = new string[ds.Tables[0].Rows.Count];
for (int loopcounter = 0; loopcounter < ds.Tables[0].Rows.Count; loopcounter++)
{
//assign dataset values to array
arrvalues[loopcounter] = ds.Tables[0].Rows[loopcounter]["PrezimeIme"].ToString();
arrvalues[loopcounter] = ds.Tables[0].Rows[loopcounter]["NetworkLogin"].ToString();
arrvalues[loopcounter] = ds.Tables[0].Rows[loopcounter]["Status"].ToString();
arrvalues[loopcounter] = ds.Tables[0].Rows[loopcounter]["OrgUnitID"].ToString();
}
report.DataSource = ds;
report.DataMember = ds.Tables[0].TableName.ToString();
}
}
catch (Exception)
{
throw;
}
}
As well as stored procedure which return filtered Report by Status Or OrgId
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[TestReport]
(
#Status bit,
#OrgJed int
)
AS
BEGIN
SELECT PrezimeIme, NetworkLogin, Status, OrgUnitId, DT_Creat, DT_Modif
FROM [DesignSaoOsig1].[dbo].[tblZaposleni_AD]
WHERE (#Status IS NULL OR Status = #Status)
AND (#OrgJed IS NULL OR OrgUnitID = #OrgJed)
END

You can do the following to bind the datasource:
using (SqlConnection conn = new SqlConnection(#"Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=DesignSaoOsig1;Integrated Security=True"))
{
string com = "SELECT DISTINCT OrgUnitID FROM tblZaposleni_AD ORDER BY OrgUnitID ASC";
SqlDataAdapter adpt = new SqlDataAdapter(com, conn);
DataTable dt = new DataTable();
adpt.Fill(dt);
ddlOrgUnit.DataSource = dt;
ddlOrgUnit.DataBind();
ddlOrgUnit.DataTextField = "text field you want to bind";
ddlOrgUnit.DataValueField = "value field you want to bind";
ddlOrgUnit.DataBind();
//add default value - you can then remove the default value from html
ddlOrgUnit.Items.Insert(0, new ListItem("-- Izaberi Org Jedinicu --","N/A")
}
The above logic should be done in the FillStatus() method too.
In your Page_Load method do the following
if (!IsPostBack)
{
FillStatus();
FillOrgUnit();
}
In the ddlOrgUnit_SelectedIndexChanged - for example - you will handle the value selected by the user accordingly - and filter for the select value - or return all.
NOTE
When you fill your DataTable(dt) from your query - you will have a table structure from the following SQL table tblZaposleni_AD
In here ddlOrgUnit.DataTextField = "text field you want to bind"; you will add the column name you want to bind as text file - eg Name
NOTE
How to use tryparse in C#
if (Int32.TryParse(ddlStatus.SelectedValue, out int theValue))
{
//is not null
sda.SelectCommand.Parameters.Add("#OrgJed", SqlDbType.Int).Value = theValue
}
// is null and you dont pass the parameter
Then in your stored procedure you set the default value for #OrgJed int to be null
ALTER PROCEDURE [dbo].[TestReport]
(
#Status bit,
#OrgJed int = NULL
)

using(sqlconnection con=new sqlconnection(cs))
{
sqlcommand cmd=new sqlcommand("select [datatextfield], [datavaluefield] from tbl",con);
sqldatareader rdr=cmd.executereader();
dropdown.datasource=rdr;
dropdown.datatextfield=rdr[0];
dropdown.datavaluefield=rdr[1];
dropdown.databind();
}

asp.net dropdownlist first selection does not fire SelectedIndexChanged event

I've created a dropdownlist, and tried clicking on the first selection but there was no firing of the SelectedIndexChanged event. However, it worked perfectly fine for the rest of the options in the dropdownlist.
Here are my codes:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string member = (String)Session["ssmem"];
if (!IsPostBack)
{
if (Session["ssmem"] == null)
Response.Redirect("LoginforAccess.aspx");
else
{
Response.ClearHeaders();
Response.AddHeader("Cache-Control", "no-cache, no-store, max-age=0, must-revalidate");
Response.AddHeader("Pragma", "no-cache");
//if go back then must log in --2
}
//Dropdownlist
string strConnectionString =
ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
//STEP1 : Define a connection to Database
SqlConnection myConnect = new SqlConnection(strConnectionString);
string strcommand = "Select Username from [User] WHERE (UsergroupID = (SELECT UsergroupID FROM [User] AS User_1 WHERE (Username = #user)))";
SqlCommand cmd = new SqlCommand(strcommand, myConnect);
// cmd.Parameters.AddWithValue("#usergrp", groupid);
cmd.Parameters.AddWithValue("#user", member);
myConnect.Open();
SqlDataReader reader = cmd.ExecuteReader();
DropDownList1.DataSource = reader;
DropDownList1.DataTextField = "Username";
DropDownList1.DataValueField = "Username";
DropDownList1.DataBind();
reader.Close();
myConnect.Close();
}
}
protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
if (Session["ssmem"] != null)
MasterPageFile = "User.master";
//change the master page --1
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
//chosen name to display stats
string choseuser = "";
choseuser = DropDownList1.SelectedItem.Text;
Response.Redirect("Substats.aspx?choseuser=" + choseuser);
}
}
Source view for dropdownlist:
<asp:DropDownList ID="DropDownList1" runat="server" Width="200px" Height="35px"
AutoPostBack="True"
onselectedindexchanged="DropDownList1_SelectedIndexChanged"
ViewStateMode="Enabled">
</asp:DropDownList>

We have to add first item as title to the dropdownlist,
and instead of using datasource used dr.Read() in while loop for adding the items on dropdownlist.
This problem occurs because in dropdownlist first item is selected bydefault and it is not reflected on selection
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" ViewStateMode="Enabled">
<asp:ListItem>Select College</asp:ListItem>
<!--Add one item as title into dropdownlist in edit item of dropdownlist-->
</asp:DropDownList>
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Response.Write("hello");
try
{
string sel = "select name from websites";
SqlCommand cmd = new SqlCommand(sel,con);
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
/* DropDownList1.DataSource = dr;
DropDownList1.DataTextField = "name";
DropDownList1.DataValueField = "name";
DropDownList1.DataBind();*/
while (dr.Read())//used dr.read() instead of datasource
{
DropDownList1.Items.Add(dr["name"].ToString());
}
}
catch(Exception ex)
{
Response.Write(ex.Message);
}
finally
{
con.Close();
}
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
SqlCommand cmd = new SqlCommand("select url from websites where name = #itm", con);
cmd.Parameters.AddWithValue("#itm", DropDownList1.SelectedItem.Text);
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
dr.Read();
if (dr.HasRows)
{
Response.Redirect(dr["url"].ToString());
}
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
finally
{
con.Close();
}
}

How Can I get the value in the gridview footer row of textbox and dropdownlist in asp.net c# webform

View state's purpose is simple:
it's there to persist state across postbacks.
That's why you are getting the initial values like empty strings in the gridview. Setting the property EnableViewState="false" force to get the data by rebinding the control, not from the viewstate. To understand view state more, see here.

How to filter query in asp.net using dropdown list?

i am using sql query to fetch the data from one dropdown list and want to change the second dropdown list by filter data i mean i am selecting the 1st dropdown list and the 2nd drop downlist show all the customer but i want the specific customer by cardcode when i select cardcode.

C# (ASP.NET) - Create Images Dynamically?

I'm trying to create a Image Dynamically. I got the Link to the Image.
necessary code:
foreach (String pictureLink in imageLinks)
{
Image image = new Image();
image.ImageUrl = pictureLink;
imagesDiv.Controls.Add(image);
}
But nothing is happens.. How can I do that or what I'm doing wrong?
The Style, of how the pictures should be showed is Googleimagesearch result like..
EDIT:
There is one more thing I would do.. When adding the Placeholders (with the Image), they are showed after all Images where been loaded, but is it possible to add the placeholder with the image, right after it has been added?

take a look at this
Adding asp.net image to div
I think it should answer your questions.
