How do I get a CheckBox in a RadGrid

[Mike]

I have several checkboxes in a RadGrid and checkBoxe 4 does an AutoPostback to DoSomething(object obj, EventArgs e). 

This works great and I don't want change anything and I use datakeys to get my values from the row.  I also don't want to loop through GridDataItems to find out if checkbox 1-3 are checked.  

<telerik:GridTemplateColumn HeaderText="Comments" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="250px" Groupable="false" ItemStyle-VerticalAlign="Top" UniqueName="CheckBoxes">
  <ItemTemplate>
     <asp:CheckBox ID="CheckBox1" Text="CheckBox 1" runat="server" /><br />
     <asp:CheckBox ID="CheckBox2" Text="CheckBox 2" runat="server" /><br />
     <asp:CheckBox ID="CheckBox3" Text="ChcekBox 3" runat="server" /><br />
     <asp:CheckBox ID="CheckBox4" Text="CheckBox 4" OnCheckedChanged="DoSomething" AutoPostBack="True"  runat="server" />
  </ItemTemplate>
</telerik:GridTemplateColumn>

II would like to see of the checkboxes for 1-3 are checked, since checkbox 4 is firing the postback "DoSomething".

protected void DoSomething(object obj, EventArgs e)
 {
    CheckBox checkBox1 = (CheckBox)obj;
    GridDataItem checkedOffer = (obj as CheckBox).NamingContainer as GridDataItem;
     if ((obj as CheckBox).Checked)
        {
          // I need to find the other checkboxes in here when someone clicks on CheckBox 4
        }
 }

Thank you in advance!

Hello Michael,

Please try the following:

protected void DoSomething(object obj, EventArgs e)
{
    TableCell cell = (obj as CheckBox).Parent as TableCell;
    foreach (Control ctrl in cell.Controls)
    {
        if (ctrl is CheckBox && (ctrl as CheckBox).Checked)
        {
            // I need to find the other checkboxes in here when someone clicks on CheckBox 4
        }
    }
}

Kind regards,

Thanks Daniel, It works great!

CheckBox check = (CheckBox)cell.FindControl("CheckBox1");
string check2 = check.Text;
