before we start I apologize for my English.

I have:

<telerik:RadAsyncUpload ID="RadAsyncUpload1" AllowedFileExtensions="JPG,gif,png,jpg,tif,tiff" MaxFileInputsCount="3" OnClientValidationFailed="OnClientValidationFailed" OnFileUploaded="RadAsploayncUd1_FileUploaded" runat="server" ChunkSize="0" Culture="it-IT" PostbackTriggers="pulsante"></telerik:RadAsyncUpload

>

<asp:Button  runat="server" ID="pulsante" Text="Aggiorna profilo"  OnClick="Button1_Click" /> 



//and in the code:



protected void RadAsploayncUd1_FileUploaded(object sender, FileUploadedEventArgs e)
        {
            RadAsyncUpload1.TargetFolder = "~/App_CProfili/ImgProfili/";
          
           }

So it works, but if I change the file name tells me that the file 'App_Data\RadUploadTemp\1378131589339001.JPG'.
was not found". For example, if I load three files are loaded only two and then goes into error

This is the code that produces the error

protected void RadAsploayncUd1_FileUploaded(object sender, FileUploadedEventArgs e)

{
e.File.SaveAs(Server.MapPath(Path.Combine(RadAsyncUpload1.TargetFolder, e.File.GetNameWithoutExtension() + User.Identity.Name + e.File.GetExtension())));
}

Problem with RadNumericTextbox since update

Hi,

I have a rad grid bound to a linq datasource.
The grind contains a template row with a RadNumericTextBox.

It runs well in the local webdev server but on IIS 6 it fires an error.
Prior the update to Q1 09 it made no problems.

Details:
If I define the thing like this

    
            <telerik:RadNumericTextBox runat="server" ID="neNumValues" MinValue="1" MaxValue="30" DbValue='<%# Bind("NumItems") %>' NumberFormat-DecimalDigits="0" Width="60px" ShowSpinButtons="True" ShowButton="False" DataType="System.Int32">  
        
                                    </telerik:RadNumericTextBox>

I get the following error

    
            Ausnahmeinformation:  
        
                Ausnahmetyp: System.Web.HttpParseException  
        
                Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.  
        
            Information zu interner Ausnahme (Ebene 1):  
        
                Ausnahmetyp: System.Web.HttpParseException  
        
                Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.  
        
            Information zu interner Ausnahme (Ebene 2):  
        
                Ausnahmetyp: System.Web.HttpException  
        
                Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.

This means in english something like it can't convert the string System.Int32 to a System.Type

If I remove the RadNumericTextBox everything works fine.
Even a GridNumeric works.
But this is not usefull for me, since (as you see) I need to ensure that the value is an integer between 1 and 30.
Currently I help me with a validator - but I would preffere to further use the RadNumericTextBox.

The strange thing for me is, that it runs at the integrated webserver and makes the problem only at the server (W2k3 IIS6)!

Regards

Manfred

bind and export from code behind?

is it possible to export like so? I am getting an error RadGrid must be databound before exporting.

I tried moving the export code to the onDataBound
ReportData.DataBound += new EventHandler(ReportData_DataBound);
but it is still giving me the same error even though I can see that the grid has 2394 items.

thanks

RadGrid ReportData = new RadGrid();

ReportData.DataSource = datasource

ReportData.DataBind();

ReportData.ExportSettings.OpenInNewWindow = true;

ReportData.ExportSettings.ExportOnlyData = true;

ReportData.ExportSettings.IgnorePaging = true;

ReportData.ExportSettings.FileName = ReportName.Replace(" ", "_") + "_" + DateTime.Now.Month.ToString() + "_" + DateTime.Now.Day.ToString() + "_" + DateTime.Now.Year.ToString();

ReportData.MasterTableView.ExportToExcel();

Radgrid column filter not triggering for backspace

I am using column filter with FilterDelay, when i key in a word, letter by letter, the grid results narrows down the result accordingly when i press a letter.

However, when i press "Backspace" the results does not grow back to the initial results.

Eg:

"C" - shows 10 rows
"Co" - shows 6 rows
"Con" - shows 2 rows

When I press "backspace"

"Co" - still showing 2 rows instead of 6.

How can i trigger the search results when "backspace" is pressed?

[Solved] Recent Windows Update causing sizing issues

ADMIN UPDATE

This is a regression issue in IE: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/11295665/.

Cast your vote by pressing the "+Me Too" button and encourage your end users to do the same if they have an account with Microsoft.

The problem with the RadWindow appearance will be fixed when Microsoft roll out a fix.

Cumulative updates through Windows Update should resolve the issue. First reported updates:

Windows 10: https://support.microsoft.com/en-us/help/4015217/windows-10-update-kb4015217.
Windows 7, Windows Server 2008: https://support.microsoft.com/en-us/help/4015549/windows-7-windows-server-2008-r2-sp1-update-kb4015549.

Fault condition description:

IE is in some form of compatibility mode (IE8, IE9 or IE10), usually via an meta tag. The issue does not manifest in standards (Edge) mode. Add a meta tag to enforce it.
RadWindow is in Classic RenderMode. It uses tables to render. Using the Lightweight RenderMode should alleviate the problem.
The end user machine has the KB4012204 update installed. Other updates that have been reported as associated with this issue: MS17-006, KB4012215, KB2952664, KB3216755, KB4013429, KB3218362.

END UPDATE

The recent Microsoft Windows Update seems to be causing issues for us with our .

https://support.microsoft.com/en-us/help/4012204/ms17-006-security-update-for-internet-explorer-march-14-2017

Attached is an example of what's happening since this update was pushed down.

Any suggestions on a quick fix?

Clients are IE 11 using Compatibility mode (v8).

[Solved] TreeList Header - Client-side Click event

Hi,

I am using the RadTreeList (Ajax) and trying to get a client-side click event for a left click on the header. This does not appear to be directly supported by the control. Is there an indirect way to get a client-side click event for the header row and determine the column of the event?

Thanks
