How would I display a RadAjaxLoadingPanel on c# function call where I'm doing some table updates and close it on return?

Note:

The user clicks on Save or Delete button, a conformation Dialog opens and if confirmed a function is called in c# to make the necessary changes in the database.

RadInputManager with Auto Generated Columns

Greetings!

My Radgrid uses a SqlDataSource that is a dynamically created pivot table. As such, the columns can be different whenever the Radgrid is loaded, and I am therfore letting the columns auto generate. Additionally, I am setting each of the fields to be editable using these two bits:

On the ItemCreated Event:

If TypeOf e.Item Is GridEditableItem Then

e.Item.Edit = True

End If

On the PreRender Event:

CType(sender, RadGrid).Rebind()

And this works for my purposes. However, as more cells are rendered, performance takes a noticeable hit. And I'm not talking about thousands of records - only dozens. I've followed a few of the steps outlined in the "Client/server grid performance optimizations" and set the ViewState to false, and I've enabled RadCompression. But I suspect that the culprit is the heavy edit boxes. Is there a way to make the MS TextBoxes load instead of Telerik NumericTextBoxes?

Thanks!

Any telerik control that solves the fieldset legend centering issue in firefox..

So I have used a DIV solution to make a div that centers the legend in all the major browsers, but it is 

not "clean" and easy...  



Has telerik made a control that will do this and allow easy legend manipulation?



I have a attached an image...

	  The primary issue is that in the
    	LEGEND tag the align=center is not longer in the w3 specs and should not be used... But
    	it is the easiest way in firefox to get it centered... 




<

fieldset>

<legend align="center" >Test Fieldset</legend>

<div>

<p>This is just an area that will hold other info...The primary issue is that in the

LEGEND tag the align=center is not longer in the w3 specs and should not be used... But

it is the easiest way in firefox to get it centered... </p>

</div>

RadGrid : Detail Table : Footer Row Export to Excel

Hi ,

I am using telerik RadGrid in my application. I want to export the RadGrid Detail Table's and Parent Table's Footer Row in the excel sheet. I have used the ExcelMLExportRowCreated event to export the footer records which contains the following code :

if (e.Worksheet.Table.Rows.Count == radGrid.Items.Count + 2)
            {



                RowElement row = new RowElement();
                GridFooterItem footer =radGrid.MasterTableView.GetItems(GridItemType.Footer)[0] as GridFooterItem;
                foreach (GridColumn column in radGrid.MasterTableView.Columns)
                {
                    CellElement cell = new CellElement();
                    String cellText = footer[column.UniqueName].Text;
                    cell.Data.DataItem = cellText == " " ? "" : cellText;
                    row.Cells.Add(cell);
                }

                e.Worksheet.Table.Rows.Add(row);
            }

This works fine for the parent table as we know exact row number for the parent table, But in case of detail table we are not able to determine. Please help me in this.

Thanks,

Multiple ResourceHeaderTemplates in Scheduler

Hi,

I was wondering if it's possible to have multiple ResourceHeaderTemplates in a Scheduler and let the correct one be chosen based on the Resource's Resource Type? I'd like to do it in markup if that is possible.
Something like (this is not valid markup):

<ResourceHeaderTemplates>

<ResourceHeaderTemplate ResourceType="1">

<div class="rsMainHeader" style="text-align: left;" >

<a href="<%# Eval("Url") %>" ><%# Eval("Text") %></a>

<br/>

<label id="projectLeaderLabel" runat="server" ></label>

<label id="participantsLabel" runat="server" ></label>

</div>

</ResourceHeaderTemplate>

<ResourceHeaderTemplate ResourceType="2">

<div class="rsMainHeader" style="text-align: left;" >

<%# Eval("Text") %>

</div>

</ResourceHeaderTemplate>

</ResourceHeaderTemplates>

RadFilterDataFieldEditor and problem with postback

Hi,

Currently using the 2013.1.220.40 version of Telerik and having a problem. At this point in time, it is not clear whether the issue is with just this version or also with previous versions.

On my page, I have two user controls both inside a radajaxpanel. I have configured it so that the init or page load do not run on the control I do not need it to run on when I have an ajax postback. (i.e. if I want to update the 1st user control, then nothing should be run in the second).

Now, one of the controls on the page has a RadFilter. A filter is set up in codebehind on the page_init. If I just update this particular control, everything works fine. However, if I update a different control, due to the skipping of the filter set up in page_init, I am getting an error... Object reference not set to an instance of an object.

More details of the error are...

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

It seems that the filter is not really handling the postback correctly. It should not run... but why does it appear to be running?

Any help on this issue would be very much appreciated.

Thank you.

Radwindow overlay creates scrollbars on first load but not second

I have two rad windows, one that opens inside the other.

On the second rad window, when made visible using server side code, scrollbars appear with vast space given to the side and below. If I close this second window and click to open this again using the same method... the window appears, but this time it is fine and without the scrollbars. Can anyone advise what is happening here and how I could possibly resolve this?

Kind Regards
