Accessing items in child grid

[Bill]

I am trying to edit a checkbox in a grid on a popup edit form and can not seem to get acces to the control I need. The basic layout is I have a page with a RadGrid. The grid has a popup edit form that has a few controls (labels and textboxes) and a new grid that is populated when you edit the parent grid. On editing the parent I get primay key from the ItemDatabound if the item is in edit mode and is a grid editform item. I then
run my query to populate the child grid with the selected details I desire.
I am trying to allow a user to check or uncheck a checkbox that I then use to update a value in the database. I can access the underlying object in the itemcommand on the update by getting a reference to the grid and they getting the EditItems to then iterate through each GridItem. I have AllowMultiEdit set on my child grid and on the child grid pre_render I set each row to edit mode.What I don't have though is the checkbox control. If I try and do a find control on the child grid in the Editform I get a null back.

Here is a snippet of how I am defining the checkbox on the child grid:

<EditFormSettings EditFormType="Template">
  <PopUpSettings Width="800" Height="500" />
       <FormTemplate>
          ...
         <telerik:GridTemplateColumn UniqueName="chkResubmitted">
            <HeaderTemplate>
                 <asp:CheckBox id="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True"
                     runat="server" Text=" resubmitted" ></asp:CheckBox>
              </HeaderTemplate>
              <EditItemTemplate>
              <asp:CheckBox id="chkResubmittedEdit" runat="server" />
              </EditItemTemplate>
              <ItemTemplate>
              <asp:CheckBox id="chkResubmittedItem" OnCheckedChanged="ToggleRowSelection"
                AutoPostBack="True" runat="server"></asp:CheckBox>
               </ItemTemplate>
               </telerik:GridTemplateColumn>

In my UpdateCommand I tried accessing the checkbox with this:

if (e.CommandName == RadGrid.UpdateCommandName)
          {
              GridEditableItem editedItem = e.Item as GridEditableItem;
              RadGrid dtlgrid = (editedItem.FindControl("grdClaimDetail") as RadGrid);

              CheckBox chk = dtlgrid.FindControl("chkResubmittedEdit");
              ...

 
Any suggestions on how I can access the checkbox on my child grid in my edit popup?

Hello Bill,

If you want to access the CheckBox in EditItemTemplate of child grid, you need to access the edit row first and then get the control like below.

C#:

GridEditFormItem editedItem = e.Item as GridEditFormItem;
RadGrid dtlgrid = (editedItem.FindControl("grdClaimDetail") as RadGrid);
foreach(GridEditFormItem childeditItem in  RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem))
    // loops through each editItem in child grid
{
   CheckBox chk = childeditItem.FindControl("chkResubmittedEdit"); //accessing CheckBox
}

Thanks,
Princy.

Thanks for the reply. I tried this:

GridEditFormItem editedItem = e.Item as GridEditFormItem;
  RadGrid dtlgrid = (editedItem.FindControl("grdClaimDetail") as RadGrid);
  GridItem[] items = dtlgrid.MasterTableView.GetItems(GridItemType.EditFormItem);
  int count = items.Length;
  if (count > 0)
  {
      GridEditFormItem clm = items[0] as GridEditFormItem;
  }
  foreach (GridEditFormItem childeditItem in items)
  // loops through each editItem in child grid
  {
      CheckBox chk = childeditItem.FindControl("chkResubmittedEdit") as CheckBox; //accessing CheckBox
  }

And no editformitems are returned. My count was zero. I thought about making the GridTemplateColumn a GridCheckboxColumn but the underlying datatype is an int and it won't explicitly cast to bool even though the values are 0 or 1 in the database.
Any other suggestions?

Hello Bill,

If you are using Inplace EditMode for child grid, please make the following modification in the above code and check if it works now. Also I feel sorry that I didnt convert the control into CheckBox type.

C#:

GridEditFormItem editedItem = e.Item as GridEditFormItem;
RadGrid dtlgrid = (editedItem.FindControl("grdClaimDetail") as RadGrid);
 foreach (GridEditFormItem childeditItem in RadGrid1.MasterTableView.GetItems(GridItemType.EditItem))
{
   CheckBox chk =(CheckBox) childeditItem.FindControl("chkResubmittedEdit"); //accessing CheckBox
}

Please paste your complete aspx code if it doesn't help?

Thanks,
Princy.
