Incorrect SelectedItems Property

[Paul]

Hi,

I am using radgrid, with client select enabled, with a client select checkbox, in order to allow multiple rows to be selected.
However, I require a callback when the selection is changed, so that I can check the status of items selected etc.

In order to do this I have the following script linked to the client side OnRowSelected and OnRowDeselected events.

function SelectionChanged(sender, args)
{
  // Refresh by calling RadAjaxManager
  $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest()
}

This creates the callback just fine.
The problem, is that the SelectedItems property of the grid has not been updated with the change just carried out.

Is there a way around this?
Do I need a different event?

thank you

Paul

Hello Paul,

If you cannot access the items inside the SelectedItems collection, you can easily create your own collection of the selected items. You can keep the ajax request approach and use the following code inside the AjaxRequest event handler:

protected void ram1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    List<GridDataItem> selectedItems = new List<GridDataItem>();
    foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
    {
        if ((item["SelectColumnUniqueName"].Controls[0] as CheckBox).Checked)
        {
            selectedItems.Add(item);
        }
    }
    //use selectedItems collection
}

I hope this helps.

Kind regards,
