Hi All,

I have to bind dropdownlist from a table in edit item template of gridview at code behind .I don't want to use SqlDataSource .

I used something like below

protected void GRVAccess_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (GRVAccess.EditIndex == e.Row.RowIndex)
{
try
{
DataTable dt1;

dt1 = desg.BindDesignation();
if (dt1.Rows.Count > 0)
{
DropDownList ddldesg = (DropDownList)e.Row.Cells[0].FindControl("ddlDesg");
ddldesg.DataSource = dt1;
ddldesg.DataTextField = "Designation";
ddldesg.DataValueField = "DesgId";
ddldesg.DataBind();
//ddldesg.Items.Insert(0, "Select");
}
}
catch (Exception ex)
{

lblErrorMessage.Visible = true;
lblErrorMessage.Text = ex.Message;
}
}
}

But it's showing Object reference not set to an instance of an object at ddldesg.DataSource = dt1;
Please help me.

Thanking You

Use following code to achieve this:

<br />
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)<br />
        {<br />
            Control ctrl = e.Row.FindControl("ddlTest");<br />
            if (ctrl != null)<br />
            {<br />
                DropDownList ddl = (DropDownList)ctrl;<br />
                List<Users> ls = GetDropDownData();<br />
                ddl.DataSource = ls;<br />
                ddl.DataTextField = "Name";<br />
                ddl.DataValueField = "Id";<br />
                ddl.DataBind();<br />
            }<br />
        }<br />

XML

<        EditItemTemplate>
                    <asp:DropDownList ID="ddlGender" runat="server" >
                    <asp:ListItem Text="male" Value="male" />
                     <asp:ListItem Text="female" Value="female" />
                     </asp:DropDownList>
                     </EditItemTemplate>

then use
<code>
DropDownList DdlGender = (DropDownList)row.FindControl("ddlGender");

string Gender = DdlGender.SelectedValue.ToString();

now you can use gender
