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:

DateTimeOffset and RadGrid.  Column does not show when this datatype is in resultset.

I have a dataTable with this datatype (DateTimeOffset) and this is the only column not showing.

I autogenerate the columns in the grid.

A workaround for now is to cast that column to datetime, or some other type in my SQL statement that generates the results.  Just curious if this is something that is being worked on or known about?

I have a radgrid set to a datatable.  Columns of type DateTimeOffset are hidden.

Why is this?

Hello Developers!

I am using Telerik Radgrid with Excel-like filters for creating my data grids. One issue I face is I cannot filter with symbol '?' or any word starting with '?' like '?check'. It immediately redirects to 500 internal error. If the symbol comes after any other character, the filter works fine, like 'o?c'.

I use RadGrid with DB source and autopopulate columns according to datasource. My filters are Excel-like filters.

I can replicate the same issue in your demo webpage for Excel-like filters too.

Placed screenshots for reference.

Could you let me know what can be done for this? It is absolutely important for me to be able to filter with '?'

Thanks and Regards

Hi,

I have  a Gridhyprlink column with a DataNavigateUrlFormatString and 2    DataNavigateUrlFields

however I want one of those fileds to be conditional on another Column;

eg

DataNavigateUrlFormatString="https://main.aspx?etn={0}&pagetype=entityrecord&id={1}"

 DataNavigateUrlFields= ((if (entityid ==2) {a} else {b}) ,mainid )

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 Team,

I have an issue with RadCombobox.
Currently we are using Telerik Version - 2015.3.1111.35 and Upgraded .NetFramework 3.5 to .NetFramework 4.8.

Tested in IE,edge and chrome - Not working.

Radcombobox dropdown click events are not firing after apppool changed to 4.0 for the first postback and 

It works for other controls in further postbacks.

Can anyone please help on this?

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:

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}";
