Hello Venkata,

Do you use GridClientSelectColumn checkboxes or Checkboxes nested inside the GridTemplateColumn? Anyways, here's examples for both sceanrios.
aspx:

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">CheckAll</asp:LinkButton>

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" AutoGenerateColumns="true" runat="server">
    <MasterTableView DataSourceID="SqlDataSource1" Name="Master">
         <DetailTables>
             <telerik:GridTableView DataSourceID="SqlDataSource1" Name="Detail" runat="server">
               <Columns>
                   <telerik:GridTemplateColumn UniqueName="CheckBoxColumn">
                       <ItemTemplate>
                            <asp:CheckBox ID="CheckBox1" runat="server" />
                       </ItemTemplate>
                   </telerik:GridTemplateColumn>
                   <telerik:GridClientSelectColumn UniqueName="SelectColumn"></telerik:GridClientSelectColumn>
               </Columns>
                  .....

-To check the checkboxes in the child grid's TemplateColumn on clicking on a button outside the grid:
c#:

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.Items)
        {
            if (item.OwnerTableView.Name == "Detail")
            {
                CheckBox chk = (CheckBox)item.FindControl("CheckBox1");
                chk.Checked = true;
            }
        }
    }

-To check the GridClientSelectColumn checkboxes in the child grid's TemplateColumn on clicking on a button outside the grid:
c#:

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.Items)
        {
            if (item.OwnerTableView.Name == "Detail")
            {
                item.Selected = true;
            }
        }
    }

if (item.OwnerTableView.Name == "grdCitations") 

{               

item.Selected = true;

Hi Venkata,

The above code will work, when the button is clicked after the items are already expanded. If you want to expand the child items and then check all the checkboxes, then you can try the following code.

CS:

    protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.Items)
        {
            if (!item.Expanded)
            {
                item.Expanded = true;
                GridTableView childtable = (GridTableView)item.ChildItem.NestedTableViews[0];
                foreach(GridDataItem childitem in childtable.Items)
                {
                    childitem.Selected = true;
                }
            }
        }
    }

Hope this helps,
Shinu.
