I am using version 2011.2.1004.40.

When I enter some value inside filter textbox and push filter button, instead of opening filter menu drop down, It raises postback with filtering "contains". If I do not enter value into textbox and click filter button it opens the menu as expected.

Any thoughts?

ajax loading user controls which contain Javascript

It seems to me that 95% of the examples you have and code you supply contains client-side javascript. This is not surprising, of course, because Telerik has created a great and powerful client-side API for most of its controls. However, shouldn't the demo you provide at:

http://demos.telerik.com/aspnet-ajax/ajax/examples/common/loadingusercontrols/defaultvb.aspx

contain a BIG warning message telling developers that this functionlity won't work if your user controls contain javascript? Unless Telerik has come up with some sort of solution recently, it is my understanding that you can't load Usercontrols containing javascript with AJAX and expect the javascript to function properly (ie load along with the rest of the usercontrol).

Client side issue: set_allowEdit(true) for Appointment doesn't allow for resize

Hey guys,

So, another issue that we've found - is that setting set_allowEdit(true) works for the purposes of dragging it around, but DOES NOT allow you to resize the appointment.

This differs from the scenario where you set AllowEdit = True in the code-behind, the appointment is both draggable and resizable as we would expect.

Is this a bug?

Client side issue: set_cssClass for Appointment

Hey guys,

So - we've noticed that when calling set_cssClass in client-side code, that it doesn't work correctly. The appointment won't display correctly, though the workaround is the following:

var backColor = apt.get_backColor();

apt.set_cssClass('appt-main'); // BUG: makes the appointment go grey without the first and last lines

apt.set_backColor(backColor);

Here's the CSS we're using:

.appt-main {

opacity:0.6;

filter:alpha(opacity=60); /* For IE8 and earlier */

}

Is this a bug?

[Solved] Raise RadButton Click Event in C#

I'm working with the RadButton, encapsulated within an asp:Login container;

An application scenario includes the requirement of programmatically accessing textbox variables, and the RadButton;

All is OK, until the C# code attempts to process the button click event, programmatically;

Object reference not set to an instance of an object results on the line of: ((IPostBackEventHandler)submitButton).RaisePostBackEvent(null);

Any insight is appreciated; Best regards - Rob

ServerSideCallBack & ExpandDepth

Hi,

I am using ServerSideCallBack and would like nodes to be expanded to say two levels.
Is there a way I can emulate the asp TreeView ExpandDepth property on load.

I have tried setting node.Expanded but this doesn't seem to trigger the populate on demand.

Many thanks

Issue: Range Column is converting to Date column while Exporting to CSV

Dear Telerik Team,

We are facing a problem with export to CSV feature using RadGrid. Actually we have a grid having a column showing range for ‘# of FTEs’ and ‘# of Freelancers’. You can find the column data in the attached file Grid.jpg. When we try to export the grid to CSV, these two columns converts to date column as shown in the attached file Excel.jpg.

Please provide us some solution for that.

Thanks

$find("RadContextMenu1") undefined

Hi
I am encountered js problem when I use below client API.
Does anyone can help me? thanks.

Case 1
var cMenu = $find("RadContextMenu1");
cMenu will be undefined!!

Case 2
var cMenu2 = $find("<%=RadContextMenu1.ClientID %>");
this is working.

but I would like to use the Case 1, due to I can pass the control's id into another function as a paramter in order to do more complex task and this way should be more fexible.

My developing environment as below.
VS2008 version 9.0.30729.1 SP
.NET Framework 3.5 SP1
telerik version is '2010.1.309.35'

Thank you!
