Checkbox and Radio Button help

[Ryan]

I have the following Rad Grid.  There is a Critical Checkbox and a set of radio buttons.  If the user Checks the checkbox I would like it to change the radio button to Failed.  Is this possible?

    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1"

Hello Ryan,

Try the following code snippet.
C#:

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
 CheckBox chk = (CheckBox)sender;
 GridDataItem item = (GridDataItem)chk.NamingContainer;
 RadioButton btn = (RadioButton)item.FindControl("FailRadioButton");
 btn.Enabled = false;
}

-Shinu.

It does not work.  I changed it a bit to use this function.

It selects the row but and goes through the if statement, how ever the radio button does not get selected.

Protected Sub ToggleRowSelection(ByVal sender As Object, ByVal e As EventArgs)

    CType(CType(sender, CheckBox).NamingContainer, GridItem).Selected = CType(sender, CheckBox).Checked

    If CType(sender, CheckBox).Checked = True Then
        Dim chk As CheckBox = DirectCast(sender, CheckBox)
        Dim item As GridDataItem = DirectCast(chk.NamingContainer, GridDataItem)
        Dim btn As RadioButton = DirectCast(item.FindControl("FailRadioButton"), RadioButton)
        btn.Checked = True
    End If

End Sub

I added a msg box and it displays btn.checked=True and the btn.text changes to show "Test".  But for some reason the radio button will not get checked.

Protected Sub ToggleRowSelection(ByVal sender As Object, ByVal e As EventArgs)

    'CType(CType(sender, CheckBox).NamingContainer, GridItem).Selected = CType(sender, CheckBox).Checked

    If CType(sender, CheckBox).Checked = True Then
        Dim chk As CheckBox = DirectCast(sender, CheckBox)
        Dim item As GridDataItem = DirectCast(chk.NamingContainer, GridDataItem)
        Dim btn As RadioButton = DirectCast(item.FindControl("FailRadioButton"), RadioButton)
        btn.Checked = True
        btn.Text = "Test"
        MsgBox(btn.Checked)
    End If

End Sub

I had to set the other radio buttons to false.
Thanks for your help.

Protected Sub ToggleRowSelection(ByVal sender As Object, ByVal e As EventArgs)

    'CType(CType(sender, CheckBox).NamingContainer, GridItem).Selected = CType(sender, CheckBox).Checked

    If CType(sender, CheckBox).Checked = True Then
        Dim chk As CheckBox = DirectCast(sender, CheckBox)
        Dim item As GridDataItem = DirectCast(chk.NamingContainer, GridDataItem)
        Dim btnFail As RadioButton = DirectCast(item.FindControl("FailRadioButton"), RadioButton)
        Dim btnNA As RadioButton = DirectCast(item.FindControl("NARadioButton"), RadioButton)
        Dim btnPass As RadioButton = DirectCast(item.FindControl("PassRadioButton"), RadioButton)

        btnNA.Checked = False
        btnPass.Checked = False
        btnFail.Checked = True
    End If

End Sub
