ExpandMode="ServerSideCallBack" and "Script control is not a registered script control" error

Hi

I'm experiencing a problem with RadTreeView when NodeTemplate has got a RadGrid inside of it. This generally works correct, but when ExpandMode="ServerSideCallBack" is used for node it gives an error message on expand, saying:

Script control 'testGrid' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

This simple test page shows the problem for me:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestGridInTree.aspx.cs" Inherits="TestGridInTree" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<script type="text/javascript" language="javascript">

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

treeView.trackChanges();

var node = new Telerik.Web.UI.RadTreeNode();

node.set_text(name);

node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack);

treeView.get_nodes().add(node);

treeView.commitChanges();

}

</script>

<form id="form1" runat="server">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<asp:Button runat="server" ID="btnAdd" Text="Add" OnClientClick="AddServerNode('client');return false;" />

<Telerik:RadTreeView runat="server" ID="TestTree" OnNodeExpand="TestTree_NodeExpand">

<NodeTemplate>

<asp:Label runat="server" ID="lblTest" Text="test" />

<telerik:RadGrid runat="server" ID="testGird" />

</NodeTemplate>

<Nodes>

<telerik:RadTreeNode runat="server" ID="node1" Text="ClientSide" ExpandMode="ServerSide"/>

<telerik:RadTreeNode runat="server" ID="node2" Text="ServerSideCallBack" ExpandMode="ServerSideCallBack" />

</Nodes>

</Telerik:RadTreeView>

</div>

</form>

</body>

</html>

Codebehind:

using Telerik.Web.UI;

public partial class TestGridInTree : System.Web.UI.Page

{

protected void TestTree_NodeExpand(object sender, RadTreeNodeEventArgs e)

{

var node = new RadTreeNode("childnode");

e.Node.Nodes.Add(node);

}

In case there is a workaround for this - please note that I would like this to work for client-side added node also (Add button in sample above).

Background-Images upload?

Hello,
I've been trying to fine-tune and add background images for different parts of both the TabStrip and the Menu e.g. Tabs->Outer Wrapper etc. , but it seems like we can't add our own images yet? All I can do is either keep or remove the existing image being used. When I click on the image file dialog in IE8, nothing hapens, in FF3.5 I get an "Image not recognized" banner on the preview control. Is this a bug or just a feature yet to be implemented? Thanks!

RadFileExplorer Upload Progress Context

Has anyone gotten the Upload Progress to work in RadFileExplorer? There is a code library here: http://www.telerik.com/community/code-library/aspnet-ajax/file-explorer/add-a-radprogressarea-inside-the-upload-dialog.aspx that goes into it and it works. I have that implemented on my site however if you are uploading say a 20MB document the upload progress bar only shows up at the end right before the file is completely uploaded. So it's like the upload is nearly complete then the upload progress bar flashes for a second then the upload is done. Here is my code:

ASCX:

function

OnClientLoad(oFExplorer, args) {

windowManager = oFExplorer.get_windowManager();

windowManager.add_show(uploadWindowShown);

}

function

uploadWindowShown(oWindow, args) {

if (oWindow.get_title() == "Upload") {// The upload window

//oWindow.moveTo(200, 100);

// Find the upload button in the Upload dialog

var uploadBtn = $get("<%= RadFileExplorer1.ClientID %>_btnUpload");

uploadBtn.onclick =

function (e) {

this.style.display = "none";

};

var progressArea = $find("<%= RadProgressArea1.ClientID %>");

// Use the button to find the parent node

uploadBtn.parentNode.insertBefore(progressArea.get_element(), uploadBtn);

}

CODE BEHIND:

protected

void RadFileExplorer1_ItemCommand(object sender, RadFileExplorerEventArgs e)

{

if (e.Command.Equals("UploadFile"))

{

RadProgressContext context = RadProgressContext.Current;

context.SecondaryTotal = Request.Files.Count;

for (int i = 1; i < Request.Files.Count; i++)

{

// A very time consumming task

context.SecondaryValue = i.ToString();

context.SecondaryPercent = i.ToString();

context.CurrentOperationText =

"Doing step " + i.ToString();

if (!Response.IsClientConnected)

{

//Cancel button was clicked or the browser was closed, so stop processing

break;

}

}

Thanks,
Adam

when getting RecurrenceRule, error Input string was not in a correct format.

Hi

When radiobutton 'every x day(s)' is checked and the days are not filled in, Getting the RecurrenceRule property from the control gives an exception Input string was not in a correct format. This looks like a bug of the control RadSchedulerRecurrenceEditor

Does anybody know a solution to this?

reset radcombobox after SelectedIndexChanged event?

I have a radcombobox and radgrid in the page, the combobox is set to EnableLoadOnDemand and AutoPostBack, EmptyMessage="Please make a selection". when user makes selection, SelectedIndexChanged event fired automatically and populates the radgrid, all worked fine.

now the requirement is that after it populates the radgrid in the SelectedIndexChanged event, I need to reset to radcombobox to the original status that showing the EmptyMessage instead of showing the current selection. I tried to clear the items and call databind, but it throws exceptions.

how can I to do that?

thanks.

Display nothing for 1/1/1900 date

I have a radgrid where I need to display nothing where the data value is 1/1/1900. It's read only - I don't need a date picker. Should I use a GridBoundColumn, GridDatetimeColumn, GridTemplateColumn, or other? How do I trap the values? I can't change the data source in this case.
