Hi Naresh,

Please try the following code snippet to select all rows on RadioButton.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" DataSourceID="SqlDataSource1"
    GridLines="None" AllowPaging="true" AllowMultiRowSelection="true" >
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridClientSelectColumn UniqueName="GridClientSelectColumn1">
            </telerik:GridClientSelectColumn>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
        </Columns>
    </MasterTableView>
    <ClientSettings Selecting-AllowRowSelect="true">
    </ClientSettings>
</telerik:RadGrid>
<asp:RadioButton ID="RadioButton1" runat="server" OnCheckedChanged="RadioButton1_CheckedChanged"
    AutoPostBack="true" />

C#:

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
   {
       foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
       {
           item.Selected = true;
       }
   }
