i got this soluiton from one of my projects it will help u just need to change the field name and column value

HTML CODE

XML

<Columns>
                   <telerik:GridTemplateColumn UniqueName="Checked">
                       <ItemTemplate>
                           <asp:CheckBox ID="chkPermission" runat="server" AutoPostBack="true" OnCheckedChanged="chkPermission_Checked" />
                       </ItemTemplate>
                       <HeaderTemplate>
                           <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState"
                               AutoPostBack="true" />
                       </HeaderTemplate>
                   </telerik:GridTemplateColumn>
                   <telerik:GridTemplateColumn UniqueName="PermissionID" Visible="false">
                       <ItemTemplate>
                           <asp:HiddenField ID="hfPermissionID" runat="server" Value='<%#Eval("PermissionID") %>' />
                       </ItemTemplate>
                   </telerik:GridTemplateColumn>
                   <telerik:GridBoundColumn DataField="PermissionTypeName" HeaderText="PermissionTypeName"
                       SortExpression="PermissionTypeName" UniqueName="PermissionTypeName">
                   </telerik:GridBoundColumn>
               </Columns>

AND IN CODE BEHIND U CAN USE FOLLOWING FUNCTION JUST TO GET THAT SELECTED ID's AND LOOP THROUGH EACH OF THEM AND DO WHATEVER U WANT TO DO

VB

Protected Sub ToggleSelectedState(ByVal sender As Object, ByVal e As EventArgs)
       'Check all checkbox
       Dim headerCheckBox As CheckBox = TryCast(sender, CheckBox)
       For Each dataItem As GridDataItem In rgPermission.MasterTableView.Items
           TryCast(dataItem.FindControl("chkPermission"), CheckBox).Checked = headerCheckBox.Checked
           dataItem.Selected = headerCheckBox.Checked
       Next

   End Sub

   'chkEmail_Checked

   Public Sub chkPermission_Checked(ByVal sender As Object, ByVal e As EventArgs)
       'Check selected checkbox
       Dim chkEmail As CheckBox = TryCast(sender, CheckBox)

       For Each dataItem As GridDataItem In rgPermission.MasterTableView.Items
           If TryCast(dataItem.FindControl("chkPermission"), CheckBox).Checked Then
               dataItem.Selected = True
           Else
               dataItem.Selected = False
           End If
       Next

   End Sub

VB

Protected Sub btnAddnPermission_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddnPermission.Click

       For Each dataItem As GridDataItem In rgPermission.MasterTableView.Items
           If TryCast(dataItem.FindControl("chkPermission"), CheckBox).Checked Then
               hfPermissionID.Value += (TryCast(dataItem.FindControl("hfPermissionID"), HiddenField).Value) + "|"
               'hfPageUserEmail.Value += (TryCast(dataItem.FindControl("emailAddress"), HiddenField).Value) + "|"
           End If
       Next

C++

If hfPermissionID.Value <> "" Then

VB

Dim test As String = hfPermissionID.Value
       Dim myStringArr() As String = Split(test, "|")
       Dim userID As Integer = CInt(ddlADUser.SelectedValue)
       If myStringArr IsNot Nothing Then
           Dim i As Integer = 0
           For Each s As String In myStringArr
               Dim IDs As String = myStringArr(i).ToString
               If IDs <> "" Then

                   Try
                       boolVal = df.InsertPermissionByUserID(userID, CInt(IDs))
                   Catch ex As Exception
                       ErrorMessage(ex.InnerException.Message)
                   End Try
               End If

               i += 1
           Next
       End If

C++

End Sub

NOTE IN MY FOR EACH LOOP ID's IS THE ID OF THE VALUE I HAVE SELECTED FROM RADGRID
AND TO STORE THAT VALUE IM USING HIDDEN FIELD IN RADGRID ITEM TEMPLATE.....HOPE IT WILL HELP YOU....
