What I am trying to do is uncheck another checkbox in the same row. I want to have a subscribe and unsubscribe checkbox columns. So when you click on subscribe the unsubscribe checkbox should uncheck and vise versa. I found a lot of entries that are similar in the forums but didnt come across anything in this. Found something in the old ASP forum but its not working. Below is what I ahve.

VB code in the page.

Private Sub grdPubList_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles grdPubList.ItemCreated

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim chk1 As CheckBox = DirectCast(item.FindControl("radchkSubscribe"), CheckBox)

Dim chk2 As CheckBox = DirectCast(item.FindControl("radchkUnsubscribe"), CheckBox)

'Dim chk3 As CheckBox = DirectCast(item.FindControl("CheckBox3"), CheckBox)

chk1.Attributes.Add("onclick", (("checkUncheck('" + chk1.ClientID & "','") + chk2.ClientID & "',')"))

End If

End Sub

Javascript in masterpage. Though i think the ch2.checked should be false in the if and true in the else.

<script type="text/javascript">

function checkUncheck(c1, c2) {

var ch1 = document.getElementById(c1);

var ch2 = document.getElementById(c2);

if (ch1.checked) {

ch2.checked = true;

}

else {

ch2.checked = false;

}

</script>

Hi Tash,

Have you verified that the javascript event is being hit when the checkboxes are checked/unchecked? If you don't have a preference to changing the checked state client side vs server side, you could subscribe to the OnCheckedChanged event of each checkbox and change it there.

I believe that something like the following would work.

I hope this helps!

protected void radchkSubscribe_CheckedChanged(object sender, EventArgs e)

{

CheckBox cbSubscribe= (CheckBox)sender;

GridDataItem dataItem = (GridDataItem)cbSubscribe.NamingContainer;

CheckBox cbUnsubscribe= (CheckBox)dataItem.FindControl("radchkUnsubscribe");

if (cbSubscribe.Checked)

{

cbUnsubscribe.Checked = false;

}

else

{

cbUnsubscribe.Checked = true;

}
