Hi
I was trying to use the following demo in my app.
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=grid

I getting the error on UI.AjaxRequestEventArgs and AjaxRequest as being undefined.

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest

I copied all imports just like shown in the demo. Any clue on why it is happening?

Thanks in advance.

Upgrade to Q2 2010 from Q1 2010 Is Causing AJAX Calls To Fail

Hi,

Yesterday I upgraded the application I'm working on from Q1 2010 (2010.1.519.40) to Q2 2010 (2010.2.713.40) and the AJAX calls began failing. The error was thrown in the Microsoft AJAX client library. If I switch from the new Q2 dll to the previous Q1 dll, the application begins working once again. I'd like nothing more than to bug hunt this one, but that time isn't available on the project at the moment so I'll have to stick with the previous version for now.

I currently have AJAX tooltips enabled in the application and when I cause the show event to fire I receive the client-side error -

Line: 5170
Error: Object required

I believe this is AJAX wide in my application as the RadGrids I am using have stopped rebinding when an AJAX rebind is requested by the client. The client-side debugger reports the error line is in the MicrosoftAjax.js file.

Hope this helps in one way or another,

Andy.

How to make Grid row initial selection?

I have FormView as master and couple RadGrids as detail and subdetail on my ASP.NET form. The relation between FormView-Grid-Grid works fine. If user clicks on a row in detail radGrid the subdetail radGrid shows filtered rows. I passing parameters to detail radGrid and subdetail radGrid as ControlParameters in SqlDataSource.

<SelectParameters>

<asp:ControlParameter ControlID="cFormView" Name="ID" PropertyName="SelectedValue"

Type="Int32" />

<asp:ControlParameter ControlID="cFormView$radGridDetails" DefaultValue="0"

Name="SubID" PropertyName="SelectedValue" Type="Int32" />

</SelectParameters>

The issue is I cannot set an initial selection. I am using the code below. But when form is loaded still no selected rows in the detail radGrid. The subdetail radGrid shows nothing because SubID has not been passed to radGrid.

protected void Page_PreRender(object sender, EventArgs e)

{

RadGrid rg = ((Telerik.Web.UI.RadGrid)(cFormView.FindControl("radGridDetails")));

if (rg.SelectedIndexes.Count == 0)

{

rg.SelectedIndexes.Add(0);

}

Sys.WebForms.PageRequestManagerParserErrorException issue

Hi,
I have page with <asp:updatepanel> and gridview. I am generating radtooltip runtime to show on hover of one of the image in grid.
The tool tip is containing a link which opens a file. And to open a file I have to use Response.WriteFile.

I came to know that it always creates issue with asynchronous postbacks like this. As in my case it is updatepanel and radtooltip.
So when I click on the link in tool tip, it shows the below error.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near 'GIF89a�<��ӓ�{��'.

I need both things, the updatepanel and rad tool tip.
Can anybody provide solution for this ASAP?

Hot to use RadComboBox's EmptyMessage Property inside a GridTemplateColumn (without empty items)?

Hi Everybody!

I have a MultiColumn RadComboBox (3 Columns) inside a GridTemplateColumn, and I'd want to use it's EmptyMessage Property only during insert mode. In fact, I'd like to replicate the RadComboBoxProduct's behavior in this Demo. I mean, when the Field is Required and we want to avoid the idea of inserting an empty item in CodeBehind .

Thus far, I've only got that behavior when the Field is NOT Required, inserting an empty item as first element, because if I don't do that, the first element is always selected during Insert Mode.

So, I'm wondering if it's possible to do the same thing illustrated on the demo?

Thanks!

IComparer Question

Something in my dataset is causing this error on my RadChart page and i'm not sure what to look for to solve the problem. Can anyone shine some light on what might cause this?

IComparer (or the IComparable methods it relies upon) did not return zero when Array.Sort called x. CompareTo(x). x: 'Item' x's type: 'ChartSeriesItem' The IComparer: 'Telerik.Charting.ChartSeriesItemComparer'.

Radcompression seems not working

Hi,

I'm facing a issue with RadCompression.
I followed RadCompression guide and also Todd Anglin's blog in configuring this control.
I've added the module in web.config (also in system.webserver because i'm using IIS7) and created the Browser file using RadHiddenFieldPageStateCompression.

But I can't see any improvement in page's size... the page size is growing!

Before the compression: 367k
after compression: 414k

Am i missing something?
thanks for the answers

Editor Stripping Spaces on PostBack

Hello,

So far, reproduced in Safari for the Mac, and Chrome on Vista. The following paragraph has spaces between all of the words it should when I paste it. However, after postback, it will have some of the spaces removed. It appears random, and it's not always the same words. Also, you have to have over a certain length (I believe) of text before the problem manifests. I've reproduced it solely by pasting from OpenOffice and Word. One of my users says she's not pasting at all, and is still experiencing the problem.

I have a ticket in for this, but I'm hoping someone has run across this and found a solution, since so far, it doesn't look promising on the support side. They've sent me a video of text being put into the editor and it not removing spaces. Heh. Anyway, here goes:

GroupCalendar provides an in-game calendar for planning, signing up, andmanaging events. It can be configured for single-guild use or formulti-guild alliances.

Dangerous Controls values clearance after back from popup windows

Hi,

actually i have a vague and dangerous problem regarding to use of normal scripted popups (not RadWindow)

in my scenario i have normal popup fires on button click from parent page wich has several controls of telerik and microsoft ajaxified with radAjaxManager.

however, in rear scenarios i am opening the popup page and doing some oporations such validation and data maniplulations (retrieval, storing)

once i back every thing will be ok till i save

the problem that controls in parent page still has its own data but on save debugger will see it values as null
one of strange behaviour that RadeDateControls successed to maintain the data

as part of problem solving i tried to replace microsoft textboxes with telerik ones but same is happining (loosing data on save as seen from debugger)

note opening the popup without any postback effort and back to parent window doesnt cause any problems...

please Help me,
Ihab - Dubai
