Programitically set a "ClientSelectColumn" to "checked"

[Bruce]

I have the following in my ASPX page
   <Columns>
    <telerik:GridClientSelectColumn Reorderable="False"  UniqueName="ClientSelectColumn">
    </telerik:GridClientSelectColumn>
    <telerik:GridTemplateColumn HeaderText="Units On Order" UniqueName="unqUnitsOnOrder" ItemStyle-HorizontalAlign="Right">
     <ItemTemplate>
      <asp:TextBox ID="txtUnitsOnOrder"  MaxLength="5" runat="server" Width="60px" Text='<%# String.Format("{0:#,##0}", DataBinder.Eval(Container.DataItem,"UnitsOnOrder")) %>' />
     </ItemTemplate>
     <EditItemTemplate>
      <asp:TextBox ID="txtUnitsOnOrderUpd" runat="server" Width="60px"  Text='<%# DataBinder.Eval(Container.DataItem,"UnitsOnOrder") %>' />
     </EditItemTemplate>
    </telerik:GridTemplateColumn>
    </Columns>

I use the following to modify a grid page at runtime

   Public Sub radGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
        If e.Item.ItemType = GridItemType.Item OrElse e.Item.ItemType = GridItemType.AlternatingItem Then
            Dim txtUnitsOnOrder As TextBox = DirectCast(e.Item.FindControl("txtUnitsOnOrder"), TextBox)
            txtUnitsOnOrder.Style("text-align") = "right" '
         End If

    End Sub

What code do I add to have a specific "ClientSelectColumn" "checked" when a grid page is displayed?

Hello Bruce,

You can use this method to select an individual item, and this one to select all items.
The client side select column checkboxes will be automatically selected.
I hope this helps.

I don't think that will help - it looks like javascript and I need something in the "codebehind".

What I 'm trying to do is to save (in a session variable) the items checked on a page so that the user can select multiple items on multiple pages, and leave the items checked as the user changes pages (so if the user goes to a page that previously had items checked,they will still be checked).  In the codebehind, when I process a grid page, I want to "check" those rows which had previously been checked.

Hi Bruce,

From the server, you can reference the checkboxes directly, within the cells where they are hosted.
Additionally, the following article demonstrates how to persist the user selection.
I hope this information helps.
