[Solved] issue of align header and cell when using Scrolling

use version:2011.1.329.35

see picture attached, the header and item cell are not align.
if I remove the setting scrolling, it works fine.

and this issue occurs only in Chrome, not in IE,Firefox, Safari,Opera, ect..

here's my code :

   <telerik:RadGrid ID="RadGrid1" EnableViewState="false" EnableLinqExpressions="False" Skin="Office2007"
   runat="server" Height="100%"
   Width="100%" AutoGenerateColumns="false" >
   <MasterTableView Caption="" NoMasterRecordsText="" >
   </MasterTableView>
   <ClientSettings >
   <ClientEvents />
   <Scrolling AllowScroll="true" UseStaticHeaders="true" />
   <Selecting AllowRowSelect="True" />
   </ClientSettings>
   <ItemStyle Height="18px" />

   </telerik:RadGrid>

any one can tell me how to fix? thanks

Simulate in place editing

Hi,
I am using the Tree List control with Auto Generate Columns set to false. I want to use in place editing, but the documentation states that in place editing is only for Auto Generate Columns. I have placed an HTML text box in an item template with an onClick event.

<input id="txtDescription" type="text" value="<%# Eval("Description") %>" onclick="Field_onClick(this, false);" onblur="Field_onBlur(this);" readonly="readonly" />

function Field_onClick(txt, allowBlank) {
    if (_mode == mode.Params) {
        _tlConfig.AllowEdit = true;
        txt.readOnly = '';
        txt.focus();
    }
}

The problem is that I have to click on the text box twice before I can edit it contents. Is there a way around this problem?

Thanks, Paul.

RadAsyncUpload save File whit new name

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?
