Q3 2011 (Version number: 2011.3.1115)

Problem: When adding items to OData enabled controls (RadMenu, RadTreeView, RadListBox, RadComboBox) through design time erroneous markup is applied to the control:

When my RadGrid is exported to Excel, if one of the cell's data begins with a dash (-), I get the error message "Excel cannot open the file because the file format or file extension is not valid..." see in the attached Error.png.  If I remove leading dashes from the data by updating the database, or remove leading dashes in code before binding it to the grid, the grid exports as expected.  However this is not an sustainable or ideal solution.

- I have tried setting the excel export to Xlsx, Html, Biff and ExcelIML in both cs code and in the designer (also tried each independent of each other):

            AuthGrid.ExportSettings.Excel.Format = GridExcelExportFormat.Xlsx;
            AuthGrid.MasterTableView.ExportToExcel();

            <ExportSettings>
                <Excel FileExtension="xlsx" Format="Xlsx" />
            </ExportSettings>

- I have tried notes.DataFormatString = "{0}"; and notes.DataFormatString = "&nbsp;{0}";

I started with a slightly older version of these dlls, but also tried upgrading to newer versions:

- Telerik.Web.Spreadsheet version 2016.3.913.40 (upgraded to 2018.3.620.40)

- Telerik.Web.UI version 2016.3.914.45 (upgraded to 2018.2.710.45)

- Telerik.Web.UI.Skins version 2016.3.914.45 (upgraded to 2018.2.710.45)

- Telerik.Windows.Documents.Core version 2016.3.913.40 (upgraded to 2018.2.619.40)

- Telerik.Windows.Documents.Fixed version 2016.3.913.40 (upgraded to 2018.2.619.40)

- Telerik.Windows.Documents.Flow version 2016.3.913.40 (upgraded to 2018.2.619.40)

- Telerik.Windows.Documents.Spreadsheet version 2016.3.913.40 (upgraded to 2018.2.619.40)

- Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXML version 2016.3.913.40 (upgraded to 2018.2.619.40)

- Telerik.Windows.Zip  version 2016.3.913.40 (upgraded to 2018.2.619.40)

Dear all,

I have the below radgrid defininition in my aspx page in which the selectionColumn is a checkbox. When I click on row, the postback is fired and I can calculate the sum of all selected rows and then display the results in the footer.

However when I click on the header checkbox, then all the lines are selected but the postback event is not fired.

Which property should be enable? Or maybe should it be managed differently?

My goal is to display in the footer, the sum of selected rows whatever it is by selection some specific rows or by using the select/unselect all checkbox.

Thanks

Dear all,

is it possible to download an older version (2017?) or a demo from back than of the RadAsyncUpload for ASP.NET AJAX?

I would need it to demonstrate a vulnerability in a university subject.

Hello,

I'm currently working on a project where I have a RadGrid displaying some data. The filter functionality is already implemented and I've created a custom skin from an existing embedded skin for the GridDateTimeColumn and implemented according to the documentation here. Everything works perfect except that upon adding the <FilterTemplate> and setting the custom skin for the <telerik:RadDatePicker> the filter button it's not generated anymore. I've inspected the page and indeed the button is not just hidden with CSS or missing it's icon, it's not present at all in the HTML and the result is in the pictures attached.

Here is the markup I'm using.

<telerik:GridDateTimeColumn DataField="foo" UniqueName="foo" HeaderText="foo" PickerType="DatePicker" DataFormatString="{0: MM/dd/yyyy}" FilterDateFormat="MM/dd/yyyy" ReadOnly="true">
     <HeaderStyle Width="130" Font-Bold="true" />
          <FilterTemplate>
               <telerik:RadDatePicker runat="server" Skin="MyCustomSkin" EnableEmbeddedSkins="false"></telerik:RadDatePicker>
          </FilterTemplate>
 </telerik:GridDateTimeColumn>

Once I remove the <FilterTemplate> and return the skin to default the Filter button is displayed. I've looked for solutions but I couldn't seem to find any. What's causing this behaviour? Is it something I'm missing? 

I'm creating a RadGrid dynamically and inserting a RadGrid into it.

When I change the RadGrid page, it disappears. How to keep the RadPageView content through Postback?

Besides that, none of RadGrid events are fired when the page changes.

My code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="PageViewProblem.aspx.cs" Inherits="WebApp.PageViewProblem" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

While following this tutorial to make my RadGrid stack columns vertically on a mobile device, I'm experiencing table width issues. 

In these screenshots, you can see that when I disable the element.style "width: 100%", the table renders as expected.  When it's enabled, the cells are all crammed in a narrow width.

So far, I've been unable to determine how to mimic this disabling in my CSS. 

Any ideas how to resolve?

Hi all,

I am wondering what is the best way to setup Ninject, ASP.NET Identity and Entity Framework? Normally (without Ninject) I would create my solution by separating the MVC project from Data project and things would work just well, but I can't really figure out the best way to add Ninject there.

Is there any good example out there? I would like to handle user authentication with roles on my ASP.NET MVC project and handle the data access via EF.

Hi.

I'm using TooltipsAppearance.ClientTemplate. It's working fine but it's inheriting the standard tooltip appearance and my template appears inside it.

Please refer to the attached image.

An example of what the tooltip should look like is also in the image. You will also notice the text in the bottom half of the tooltip is not showing. It is actually there but the text color is white so you can't see it. 

What am I doing wrong?

Thanks.
