Server-side access to Radgrid and children in Template Column of Radgrid

[Robert]

Hello,
 
I have a Radgrid with another radgrid in an Editform template.

An example of the structure below: 

Radgrid1
    Editform Template
                RadTab/multipage
                        Radgrid2
                                Master Table
                                        Detail1
                                            Detail2

I have a number things which I want to do server-side on the Details2 grid such as inserting footer fields, changing row colors etc.

How do I access the Radgrid2 and children server side (only Radgrid1 appears as a directly accessable object).
I'm new to ASP.Net programming so I'm probably missing something obvious. I'm used to dropping in a control and then being able to program against it server side immediately.

Thanks
Robert

Hello Robert,

Try the following code.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridEditableItem && e.Item.IsInEditMode)
 {
  GridEditableItem item = (GridEditableItem)e.Item;
  RadPageView page = (RadPageView)item.FindControl("RadPageView1");
  RadGrid grid=(RadGrid) page.FindControl("RadGrid2");
 }
}

Hello,

After getting the grid you can access Detail table view by below code

// Method 1
      foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
      {
          if (item.HasChildItems)
          {
              // if Detail1 and Detail2 are in same level
              // for Detail1
              foreach (GridDataItem citem in item.ChildItem.NestedTableViews[0].Items)
              {

              }

              //for Detail2
              foreach (GridDataItem citem in item.ChildItem.NestedTableViews[1].Items)
              {

              }

              //OR
              // if Detail1 and Detail2 are NOT in same level
              // for Detail1
              foreach (GridDataItem citem in item.ChildItem.NestedTableViews[0].Items)
              {
                  if (item.HasChildItems)
                  {
                      //for Details
                      foreach (GridDataItem citem2 in citem.ChildItem.NestedTableViews[0].Items)
                      {

                      }
                  }
              }
          }
      }


      // Method 2

      foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
      {
          // please give different for MasterTableView,DeTailTable
          if (item.OwnerTableView.Name == "GridName")
          {

          }
      }

Thanks,

Thanks Shinu,
I'm using VB and using your code can find Radgrid6 however how do I access the details tables.
As below on the 6th line of code I try to access the nested table view but "grid.MasterTableView.Items[0]" expects an identifier and "[0]" creates an error).

 

 

 

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim item As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim page As RadPageView = DirectCast(item.FindControl("RadPageView5"), RadPageView)
        Dim grid As RadGrid = DirectCast(page.FindControl("RadGrid6"), RadGrid)
        Dim nestedTableView as GridTableView = CType(grid.MasterTableView.Items[0], GridDataItem).ChildItem.NestedTableViews[0]
    End If
End Sub

Thanks a lot
Robert

Thanks Jasesh,

However I'm looking to access the children to a radgrid sitting in the editform template of Radgrid1 rather than the children of radgrid1 it self. I've managed to access these using the code here: http://www.telerik.com/help/aspnet-ajax/grid-traversing-detail-tables-items-in-grid.html

Cheers

I have a RadGrid which has rows but when I try to read the rows in server side using following code, RadGridARSearch.MasterTableView.Items count is always zero. But Grid has one row with the checkbox checked.

foreach (GridDataItem item in RadGridARSearch.MasterTableView.Items)
{
CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];

 

FYI..

I tried even

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="divFormatID">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="divFormatID" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManagerProxy>

Can u help on this?
