Check CheckBox GridHeardItem when checkbox GridDataItem is checked or unchecked

[Andrew]

How do i find the GroupHeader checkbox from the subgroup checkbox. Here is my code, it toggles between data item checkbox checked or unchecked. The problem I having is that I have a grouping of checkbox. This code is selecting the header level and not the group level of the checkbox. How can I select a check box item that will update the group checkbox?

 

 protected void ToggleRowSelection(object sender, EventArgs e)
        {
            ((sender as CheckBox).NamingContainer as GridItem).Selected = (sender as CheckBox).Checked;
            bool checkHeader = true;
                foreach (GridDataItem dataItem in rgvFunctions.MasterTableView.Items)
                {
                    if (!(dataItem.FindControl("isFunction") as CheckBox).Checked)
                    {
                        checkHeader = false;
                        break;
                    }
                }
               
            GridHeaderItem headerItem = rgvFunctions.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;
            (headerItem.FindControl("CheckAll") as CheckBox).Checked = checkHeader;


            
        }

Hello Andrew,

Looking at the shared code line, it seems your question is not related to Telerik Platform and generally I would suggest you to post it under the respective forum category. In this case, you already opened another request under UI for ASP.NET AJAX forum and it is already answered. For anyone interested in the answer, it can be found here.
