Hi,
i have a scenario where i use the grid inbuilt sorting inbuilt sorting behaviour:

    
            <sortexpressions> 
        
                    <telerik:gridsortexpression fieldname="Sort" sortorder="Ascending" /> 
        
            </sortexpressions>

i got an undersired behaviour instead of having row sorting from 1- 15, i get 1-10-15- 2-9. as seen in the attached a screen shot.

Regards;
Adrian

[Solved] Third party Export not working on Item Command event

Hi,
I am using Q1 2010 AJAX ASP.Net controls for development.

I have one RadGrid placed on page, and on ItemCommand event i am exporting crystal report to pdf (working with response) then it gives me an error like:
{Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

One thing to be note is that same is working on any event of asp control.
This happens when I use RadAjaxManager in my page.
My code for same is as below:

    
            // Get the report document 
        
                    CrystalDecisions.CrystalReports.Engine.ReportDocument repDoc = GetReportDocument(); 
        
                    // Stop buffering the response 
        
                    Response.Buffer = false; 
        
                    // Clear the response content and headers 
        
                    Response.ClearContent(); 
        
                    Response.ClearHeaders(); 
        
                    try 
        
                    { 
        
                        repDoc.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, false, "Invoice"); 
        
                    } 
        
                    catch (System.Threading.ThreadAbortException ex1) 
        
                    { 
        
                        ex1 = null; 
        
                        Response.End(); 
        
                    } 
        
                    catch (Exception ex) 
        
                    { 
        
                        ex = null; 
        
                    } 
        
                    finally 
        
                    { 
        
                    }

Please suggest to overcome this issue.

IE and "out of memory"

We have a page which is getting the results of a file system folder/file scan that will occasionally throw an ":out of memory" pop-up to the user (and the list of folders which is within a RadListBox, will actually flow over the box boundaries and down off the bottom of the page); close the browser, re-launch and log in and hit the same page again and it will work just fine.

Below is the sub that scans the file system & loads the list - it seems to all work ok every time - it is the rendering that seems to be taking the hit.

My dev team is not able to identify any specific causes for this - was wondering if anyone has seen this or has any suggestions for debugging or correction.

    
                Private Sub LoadItems(Optional ByVal bolClearText As Boolean = True)  
        
                    If bolClearText Then  
        
                        lblFinished.Text = ""

[Solved] RadScheduler Data binding Issue

Hi,
I have Scheduler in my aspx form. I need to bind the events in the scheduler. I have an issue in binding the Provider for that scheduler. I have seen the demo where i found the Provider was set as XMLSchedulerProvider.

    
             provider = new XmlSchedulerProvider(Server.MapPath("~/App_Data/Appointments.xml"), false);

But I have the data as an IList collection. I dont know how to convert it into XmlScheduler and bind to the source.

Please help me. is there any direct way to convert the iList to XmlScheduler ? I need urgent solution for this, I have reffered the following link but dint get complete understanding.
http://demos.telerik.com/aspnet-ajax/scheduler/examples/xmlschedulerprovider/defaultcs.aspx
