I have a table which contains userid,productid,permission . Userid and productid are inserted from a page and permission is getting false automatically since default value is false . Now i want to show the userid ,productid and permission in a grid view and if admin wants it will check and make true the permission .

I take a checkbox on the page for that and on rowdatabound when checkbox.checked ! = null then i inserted true and take that value in session . And then update in the table on the button click but checking the check box not working .

Hi,

Here I write some code for checking checkbox in data controls

ASP.NET

<asp:datalist id="DataList1" runat="server" width="70%" onitemcommand="DataList1_ItemCommand" xmlns:asp="#unknown">
          <HeaderTemplate>
              <table width="100%" align="center" border="1">
          </HeaderTemplate>
          <itemtemplate>
              <tr>
                  <td>
                      <asp:checkbox id="CheckBox1" runat="server" />
                  </td>
                  <td>
                      <asp:linkbutton id="LinkButton1" commandname="changepremi" commandargument="<%#Eval("Userid")" runat="server">change</asp:linkbutton>
                  </td>
              </tr>
          </itemtemplate>
          <footertemplate>
              </footertemplate></table>

      </asp:datalist>

And code behind file contains following code

C#

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
    if (e.CommandName == "changepremi")
    {
        string id = e.CommandArgument.ToString();
        CheckBox chbox = (CheckBox)e.Item.FindControl("CheckBox1");
        if (chbox.Checked)
        {
            // update database
        }
        else
        {
            //update database
        }
    }
}

I hope my guess is right in your question .We cannot raise data control event with checkbox in data control except selectedchange event.

All the Best

You are right sir, But i want that on the place of update database , the checkbox value will be true and then i store it in the session . And when user clicks on the submit button then it will be inserted . Because if user checked and then unchecked it its value is already inserted in the database

Muralikrishna8811 5-Oct-11 5:56am

can you post your design code

Vimalrashamra 5-Oct-11 6:49am

Thanks Murli for help . Its working fine now .

Vimalrashamra 5-Oct-11 6:54am

but a problem still occurs when i check any checkbox its take all the checkbox as checked

Muralikrishna8811 5-Oct-11 6:57am

check your data filling method must be in
if(!ispostback)
{
//fill data
}

Vimalrashamra 5-Oct-11 7:09am

On checking only one row it makes the whole column true .
Actually i have to do it for a row

Muralikrishna8811 5-Oct-11 6:47am

make sure your control ids are correct

place break point on page load and trace where you got that error

Vimalrashamra 5-Oct-11 7:19am

when i check only one row and makes its entry in table then it makes whole rows value true .

Muralikrishna8811 5-Oct-11 8:19am

post your code plz

without your code we can not figure out your problem
