Sys.WebForms.PageRequestManagerServerErrorException: There was a problem extracting DataKeyValues from the DataSource. Please ensure that DataKeyNames are specified correctly and all fields specified exist in the DataSource.

Client-side databind only on demand

I'm implementing client-side databinding on a grid.
On the page's initial load the grid is automatically binded on client-side although the user should specify some data first.
So, with javascript, is there a way to rebind the grid only when rebind() is manually called? For example rebind is automatically triggered when filter() is called.

Thanks

How to set control's left style in RadGrid's OnFilterMenuShowing event

OnFilterMenuShowing event of RadGird sets "Left" css style as "this.Control.style.left=e.clientX+document.documentElement.scrollLeft+document.body.scrollLeft+5+"px";"
This will make the filter menu appear next to the current mouse pointer. We are in need of showing the filter menu before the current mouse pointer. Please suggest us how can we override "this.Control.style.left " property.

Attached a rad grid page with filter options enabled in grid header. If the user clicks on the right most filter menu the page is going out of scope. We where tring to show this filter menu before the mouse pointer. Is there a way to do that? Kindly help.

Selecting Initial Folder in ImageManager

Hi Folks,

In Editor we use a Custom File Dialogs Content Provider for the ImageManager.
Now, we try to show a certain directory when opening the ImageManager.

We set the SelectedUrl to some path but it has no influence.
We managed somehow to show the correct files in the right hand panel but on the left hand side always the first folder is selected.

We tried already this:
http://www.telerik.com/support/kb/aspnet-ajax/editor/select-an-image-or-folder-when-imagemanager-is-first-shown.aspx

It doesnt work either, i think because of the Custom Content Provider.

What else can we try?

Thanks a lot
Regards
Felix

Fail operation of Drag To Group, Filtering, go to Second page of Grid

I have remove the below Script:

<%@ Register TagPrefix="telerik" Namespace="Telerik.QuickStart" %>
<%@ Register TagPrefix="telerik" TagName="Header" Src="~/Common/Header.ascx" %>
<%@ Register TagPrefix="telerik" TagName="HeadTag" Src="~/Common/HeadTag.ascx" %>
<%@ Register TagPrefix="telerik" TagName="Footer" Src="~/Common/Footer.ascx" %>
<%@ Register TagPrefix="sds" Namespace="Telerik.Web.SessionDS" %>

then, when I added these functions (as title), it has an error at the run time. the error occur when I do the action both Drag To Group, Filtering, go to Second page of Grid. it said:
Microsoft JScript runtime 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.

But, it is work if I select row, resize the column width and my other function in my web, so I can confirm that is only error occur when Drag To Group, Filtering, go to Second page of Grid.
