Questions on UI for ASP.NET AJAX Forum

my situation is based on this example: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=grid

the main differences in my scenario are that i am calling the radwindow from a grid hosted in an ajax control toolkit tab form. i have a radajaxmanager declared on the page outside of the scope of the tab. the first tab contains a grid whose selection drives the data selection results of two grids on another tab and 1 grid on a third tab. the third tab contains a radwindowmanager and radwindow which is opened from the grid. a selection is made whereupon a button click event of the radwindow (aspx.cs) writes the data and then calls for a refresh of the parent grid as follows:

ClientScript.RegisterStartupScript(Page.GetType(), "registerkey", "CloseAndRebind('Registration');", true);

which calls this from the radwindow (aspx) :

function CloseAndRebind(args) {

GetRadWindow().BrowserWindow.refreshGrid(args);

GetRadWindow().close();

}

which calls this from parent page's tab (aspx)

function refreshGrid(arg) {

if (!arg) {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequest();

}

else {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequest(arg);

}

which finally calls this in the aspx.cs

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

RadGrid1.Rebind();

RadGrid2.Rebind();

RadGrid3.Rebind();

}

tab2 (with 2 grids) has radajaxmanagerproxy and the tab works well. tab3 with radgrid3 works ok when updated by tab1 grid1 but not when updated from the radwindow. i have tried radajaxmanagerproxy on tab 3 grid 3 with no success with and without a radajaxpanel.

i have never been able to debug into the ajaxrequest - not sure if it is possible. i have configured radajaxmanagerproxy through its editor but it does not see the radajaxmanager.

any ideas about why tab3 will not rebind?

i don't need to update all of these grids each time but for now i am using this bloated code until i can get tab 3 to update properly...

Width of Filter DropDown

My Customer names are very long. So, in the filter column, it seems I need to stretch the Customer dropdown to see the down-arrow icon on the right. My attachment shows this; it is too long.

How may I make the dropdown shorter in length and still see the down-arrow icon?

Thank you.

Rick

Displaying single loading panel in master page for for all postbacks in the website

Hi,
I have this requirement of displaying the LoadingPanel for all post backs in the website's content pages. So what I did is to add the RadAjaxLoadingPanel on top of the ContentPlaceHolder of the master page as shown below. This is working for even user control's post back in the content page in my test application. So I wanted to know if the approach is correct or in future I will get some issues with this approach not working for some controls or something? Can you please point out any disadvantages of this approach ?

Followed the instructions provided in the following link, http://www.telerik.com/help/aspnet-ajax/moss-sp2010-different-configuration-files-for-different-webs.html, however the RadEditor does not display the appropriate css classes in the dropdown. I'm pretty certain I've missed something, but am not sure what.

No property or field 'RecordID' exists in type 'EntityDataSourceWrapper'

I'm using an EntityDataSource with the RadGrid. Everything was working fine until I added a GridCalculatedColumn. Suddenly, I'm getting this error:

No property or field 'RecordID' exists in type 'EntityDataSourceWrapper'

As you see in the markup at the end of the message, I'm declaring the EntityDataSource declaratively. I encountered a similar problem with the EntityDataSourceWrapper previously in the code behind and managed to find a fix that I posted here:

http://weblogs.asp.net/kencox/archive/2009/07/16/fixing-entitydatasourcewrapper-error-in-ef-vb-version.aspx

Does anyone know a workaround for this when using the EntityDataSource declaratively?

RadAsyncUpload broken in IIS7 integrated mode or controlRenderingCompatibilityVersion = "4.0"

I have been having problems with a RadAsyncUpload control that was previously working in ASP.NET 3.5 after I converted imy app to ASP.NET 4.0. I confirmed that all my web.config settings were correct. When I selected a valid file, I would get the exclamation point as if I had chosen a file that failed validation. I did not see any javascript errors in Firebug, and I had no error messages coming out of it. I knew that the file I selected wasn't the problem, and no changes had happened in the code since the upgrade to .NET 4.0. Changing IIS 7 to "classic mode" made it go away, but that was not an option for me. Plus I knew that integrated mode shouldn't be the issue since I had all the appropriate web.config settings. After a bit of trial and error, I found that if I set "controlRenderingCompatibilityVersion" in the web.config to 3.5, the error went away.

I wanted to post this to share it with the rest of the community, and alert Telerik to a potential bug.
