Im having some trouble understanding why I cant access columns within the PreRender function. Here is the code. I am loading the grid at runtime.

Why do I not get inside of either of these loops? But, the commented code will set the ID columns visibility to false if uncommented.

Private Sub RadGrid_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid.PreRender

For Each column As GridColumn In RadGrid.MasterTableView.Columns

If column.UniqueName = "ID" Then

column.Visible = False 'Not column.Visible

End If

Next

For Each column2 As GridColumn In RadGrid.Columns

If column2.UniqueName = "ID" Then

column2.Visible = False 'Not column.Visible

End If

Next

'Dim column3 As GridColumn = RadGrid.MasterTableView.GetColumnSafe("ID")

'If column3 IsNot Nothing Then

' column3.Visible = False 'Not column.Visible

'End If

RadGrid.MasterTableView.Rebind()

End Sub

Here is the PageLoad just in case.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack() Then

Dim bp As BasePage

bp = CType(Parent.Page, BasePage)

RadGrid.DataSource = bp.mDs

bp.ExecuteQuery(" WHERE 1 = 0 ")

End If

End Sub

Sort Listbox items

Hi Telerik team,

I am Telerik user and I have an requirement as below:

Right now, Telerik RadListBox doesn’t support Dropped event (it is not fired when dropping an item over another RadListBox/RadListBoxItem). So, how can I sort AvailableList’s items whenever an item is dropped into it?

I have tried to work around by firing two event OnInserted and OnUpdated, but it seems hopelessness (these two events were fired one by one after an item was dropped into AvailableList), and it threw exception like:

Line: 6

Error: Sys.WebForms.PageRequestManagerServerErrorException: Insertion index was out of range. Must be non-negative and less than or equal to size.

Parameter name: index

It’s urgent, any solution please?

Many thanks,

Bo

Checkbox Hide UncheckAllNodes

I have a RadTreeView set up so that the lowest level of the tree has a check box. It has many nodes so I have implemented the Page Methods functionality. I am trying to decrease the level of clicks by using the UncheckAllNodes() method on the tree. On tree load I have a javascript function that will hide the original node and I created a custom RadTreeNodeData class that has an object ShowCheckBox and Checked objects. When I call the UncheckAllNodes, I need it to be on the lowest level, instead what I'm getting is all nodes unchecked (expected), but the check boxes are showing up for the non-lowest level nodes. Is there a function I could call that will re-hide the check boxes, or a function that will un-check nodes that are checked? That way it won't affect the style I've applied to the nodes above?

function TreeViewLoad() {

var treeView = $find("<%=TreeView.ClientID%>");

if (treeView != null) {

var node = treeView.get_nodes().getNode(0); //get the first node

node.get_checkBoxElement().style.display = "none"; // hide the CheckBox

}

function OnClientNodeDataBoundHandler(sender, e) {

var node = e.get_node();

if (e.get_dataItem().ShowCheckBox) {

node.set_checked(e.get_dataItem().Checked);

}

else {

node.get_checkBoxElement().style.display = "none"; // hide the CheckBox

}

element 'xxxx' is not a known element

Hi,
I am using Visual Studio 2010 with Framework 4.0 and the Telerik.Web.UI and Telerik.Web.Design dlls are versioned at 2010.3.1317.40
I have been having problems adding a user web control to an aspx page via mark up and have been getting the error shown above.
The user control is one of a series of user controls some of which incorporate Telerik RadComboBox controls. Any user control which does not have a Telerik RadComboBox control within it can be found and added to the page markup without the error occurring.

Markup page Inherits from:
ScottishParliament.QAndMSearchControls.QAndMSearch (with QAndMSearch being the name (and class) of the aspx page).
The Telerik.Web.UI Assembly is registered on the markup page using:
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik>Web.UI" TagPrefix="telerik" %>

The aspx page references the Telerik assemblies Telerik.Web.Design and Telerik.Web.UI found by browsing.

Each control is Registered on the mark up page. All (working and non-working) reside in the same child folder. They are all assigned a tagPrefix of uc and a TagName matching their ControlName with Src pointing to the relative path of the ascx file involved.
Eg
<%@ Register TagPrefix="uc" TagName="MSPUC" Src="~/ChildUserControls/MSPUC.ascx" %>

I am trying to add the control to a asp:panel control using
<uc:MSPUC ID="MSPUC1" runat="server" />

There is a Script Manager in place at the head of the list of user controls as I am aware that the Telerik drop list requires one. This is entered as:
<telerik:RadScriptManager ID="ScriptManager2" runat="server" EnableTheming="True" />

The aspx page written in c# is part of namespace ScottishParliament.QAndMSearchControls.
It has a 'using ScottishParliament.QAndMSearchControls.ChildUserControls;' statement at the top.

All user controls (those that use Telerik components and those that don't) all belong to namespace 'ScottishParliament.QAndMSearchControls.ChildUserControls.
The example control MSPUC does not work and has an ASP Label and ASP DropList as well as a Telerik RadComboBox. These all appear on the Designer.cs page and can be referenced in the user control's own code page without problems.
The control's own Markup page registers the Telerik Web UI assembly in the same way as the aspx page.

I can't work out why there is a difference in behaviour from these controls and after some investigation found that removing the telerik component from the user control and re-building allowed me to add the control to the aspx mark up.
I had read from somewhere that it might be a trust issue resulting in the Telerik assemblies not being found?

Thanks for any help that can be provided in advance.

Pageview goes blank for "non first tabs"

Well...another issue which I am unable to resolve...lemme explain

I have an ascx page...which I want to load into a tab...now the issue is that I am able to load the tab in the first tab...but when I load the user control in the second tab...it goes blank and doesn't show anything...this is happening just for my user controls...

Now when I have a simple gridview with a sql datasource in another usercontrol...this time I am able to load this properly in the "child" tabs...no issues whatsoever.

The issue pertains to only loading of user controls in child tabs where I have multiple asp tools embedded in that particular user control...something like the one which is shown below.

                    <asp:GridView ID="grdContent" runat="server" AutoGenerateColumns="false" Height="124px"
