When I get the popup that says "Error loading Radchart image.... Display Stack Trace?" and hit "OK", I get a blank page. How can I disable this all together and have .NET show me the stack trace?

Thanks!

<HeaderTemplate>

<table>

Simple question, looking for a simple answer: How do you change the hover color in RadMenu ?

Simple question, looking for a simple answer: How do you change the hover color in RadMenu ?

So far my research has shown me nothing but seemingly overcomplicated measures (custom CSS classes etc.) just to change what you would think would be a fairly obvious control paramater.

The Black skin has a default hover color of green, I need it to be orange...it's that simple !

If anyone can tell me where the control setting is for that, I would greatly appreciate it (I find it hard to believe that cusom CSS is required to modify such an obvious thing). I also looked though the CSS file for the Black skin, and there was one hex value that was green, after changing that to orange, the green remained anyway...

Totally frustrated,

Bazz

OnClientDragEnd, MasterPage issue

Hello, I have a master page that contains a RadWindowManager, with a number of RadWindows Defined. I have working code from an earlier project in which no master page was used, where I can save the window's position after it's moved, by using the OnClientDragEnd event. This does not seem to get fired in the master page version. Here is the RadWindowManager from the master page:

<telerik:RadWindowManager ID="RadWindowManagerMaster" runat="server" OnClientDragEnd="WindowMoved" PreserveClientState="true"

Behaviors="Close, Move" Behavior="Close, Move">

<Windows>

<telerik:RadWindow ID="BinAssignmentDialog" runat="server" Title="Bin Assignment" Height="384px"

Width="530px" Left="400px" ReloadOnShow="true" OnClientDragEnd="WindowMoved"

ShowContentDuringLoad="false" Modal="true" VisibleStatusbar="false"

Top="80px" />

</Windows>

</telerik:RadWindowManager>

The window is apparently using this definition as the window size agrees with the above. The code that opens the window follows:

function ShowBinAssignmentDialog(bintolotid) {

var oWndMgr = $find("<%= RadWindowManagerMaster.ClientID %>");

var oWnd = oWndMgr.Open("BinAssignmentDetail.aspx?btl=" + bintolotid, "BinAssignmentDialog");

var x = readCookie('BinAssignmentDialogLeft');

var y = readCookie('BinAssignmentDialogTop');

if (x) {

oWnd.moveTo(x, y);

}

else {

oWnd.moveTo(80, 80); // move to top left

}

return false;

}

The client method "WindowMoved" looks like the following:

function WindowMoved(sender, args) {

debugger;

window.setTimeout(function () {

SaveSizeAndPosition(sender, args);

}, 10);

}

Yet the debugger is never hit. This arrangement worked before I moved the RadWindowManager to the master page. Any suggestions would be appreciated.

Putting DetailTables in edit mode

Hi.

I'm using the method below to place all rows in edit mode...

for (int i = 0; i < RadGrid1.PageSize; i++)

{

RadGrid1.EditIndexes.Add(i);

}

RadGrid1.Rebind();

It works fine but my RadGrid has three levels of parent child relationships and this only works on the first level. How do I get it to affect all levels? Thanks in advance.

Menu

I have a RadMenu on the MasterPage. In the content page when a button is clicked a RadWindow pops up. But a part of this window is overlayed by the menu control so I'm not able to close the window. Is there a property on the RadMenu that sets the window on the top?

Thank you,
Neelima

[Solved] Can't see all-day event in Month View

I have a RadScheduler set up, but when I switch to Month View (which is the default view), I cannot see all-day events. These events show up as a thin (maybe 2px wide) line, with the proper height. I cannot see any details unless I hover directly over the event. Is there any way to change this so that all-day events appear just like the other events in month view?

Dynamic load problem!

Hi,

this one is a bit urgent, I need to implement it asap.
In my application I have several update panels and everything is loaded dynamically (parent controls load child controls etc).
I'm having an issue loading a control that has ImageEditor inside, I get:

Object reference not set to an instance of an object. at System.Web.UI.AsyncPostBackTrigger.HasTriggered() at System.Web.UI.UpdatePanelTriggerCollection.HasTriggered() at System.Web.UI.PageRequestManager.ProcessUpdatePanels() at System.Web.UI.PageRequestManager.RenderPageCallback(HtmlTextWriter writer, Control pageControl) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Page.Render(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Please create a new VS 2010 Rad controls project (.NET 4.0). Next create 2 user controls: MainContainer and PageImageEditor

MainContainer is:

<asp:UpdatePanel ID="up" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<asp:PlaceHolder ID="ph" runat="server"></asp:PlaceHolder>

<asp:Button ID="btn_TestLoad" runat="server" Text="Test load" onclick="btn_TestLoad_Click" />

</ContentTemplate>

</asp:UpdatePanel>

and cs file:

private void LoadOwnControl()

{

Control ctrl = LoadControl(CurrentLoadedControlName);

ph.Controls.Clear();

ph.Controls.Add(ctrl);

}

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

if (Session["CurrentLoadedControlName"] != null)

LoadOwnControl();

}

protected void Page_Load(object sender, EventArgs e)

{

}

private string CurrentLoadedControlName

{

get

{

if (Session["CurrentLoadedControlName"] == null)

Session["CurrentLoadedControlName"] = "~/DummyControl.ascx";

return Session["CurrentLoadedControlName"] as string;

}

set { Session["CurrentLoadedControlName"] = value; }

}

protected void btn_TestLoad_Click(object sender, EventArgs e)

{

CurrentLoadedControlName = "~/PageImageEditor.ascx";

LoadOwnControl();

}

PageImageEditor is just:

<telerik:RadImageEditor ID="RadImageEditor1" runat="server">

</telerik:RadImageEditor>

Drop MainContainer user control in Designer to Default.aspx:

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

<%@ Register src="PageImageEditor.ascx" tagname="PageImageEditor" tagprefix="uc1" %>

</telerik:RadAjaxManager>

<div>

<uc2:MainContainer ID="MainContainer1" runat="server" />

</div>

</form>

</body>

</html>

start the project, click the button and you will instantly get error:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

also give a try and comment out UpdatePanel code (not placeholder and button) in MainContainer, you will not get this error, but dialogs of ImageEditor won't load anything except their title (not sure if this is the only thing that doesn't work, didn't check, cause it didn't make sense to proceed further).

So question is basically how to make this work in scenario described when control in inside UpdatePanel.

Thank you!

P.S.: in current project similar technique is applied to several other Telerik controls, no similar (major) problems faced so far.
