You can do this by writing some code as below in grid view RowDataBound event

C#

protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
CheckBox chk = (CheckBox)e.Row.FindControl("<name of check box>");

if(DataBinder.Eval(e.Row.DataItem, "<database field>").ToString() == <somevalue>)
   chk.Checked= true;
else
   chk.Checked= false;
}

Good Luck
Keep Coding

Use This Code On 'aspx' for Adding checkbox in gridview

ASP.NET

<asp:TemplateField HeaderText="Select">
<ItemTemplate>
   <asp:CheckBox ID="chkSelect" runat="server" />
  </ItemTemplate>
</asp:TemplateField>

After this write code on aspx.cs

C#

foreach (GridViewRow row in gridview1.Rows)
        {
            for (int i = 0; i < gridview1.Rows.Count; i++)
            {
                CheckBox chk = (CheckBox)row.FindControl("chkSelect");
                chk.Checked = true;
            }
        }

try this..............

Solution 3

If you want to uncheck previously checked checkbox after checking some other checkbox at runtime....this means you want to keep only 1 checkbox checked at a time.
If this is the case, i would suggest you to use radio button in place of checkbox.

You need to loop through all rows of gridview and find radio button control on each row.
Then you can use Checked property of radio button on each row to save yes or no.

ya i m doing this but can u provide me coding for that i mean step by step.....plz

pallavi ajin 4-Oct-11 8:15am

I M DOING THIS ON THE CLICK EVENT OF BUTTON
foreach (GridViewRow row in GridView1.Rows)
{
RadioButton rbtn = (RadioButton)row.FindControl("RadioButton1");
HiddenField hdfID = (HiddenField)row.FindControl("HiddenField1");
if (rbtn != null && rbtn.Checked)
{
strSQL = "update addrecipes SET [IsActive]=1 where ID=" + hdfID.Value + "";
du.ExecuteDML(strSQL);
}
}

Are you getting any error in this code?
Why are you putting rbtn.Checked in if condition? This way u won't get false value.
