I'm using the RadMultiColumnComboBox control with the GridViewItemsSourceProvider. It's showing a validation error that something "cannot be empty" and I can't get it to go away. Because this control is just used to select a record, I don't want any kind of validation in the grid of any kind. I've tried setting these properties on the bindings for each column:

ValidatesOnDataErrors = false,
ValidatesOnNotifyDataErrors = false,
ValidatesOnExceptions = false,
NotifyOnValidationError = false,

I've also tried setting the grid view's validation mode to none. I've tried setting these properties on the columns:

IsReadOnly = true,
ValidatesOnDataErrors = Telerik.Windows.Controls.GridViewValidationMode.None

Nothing works.

Hello,

I'm using Telerik for WPF, version 2020.1.218, and I am using  RadGridView with filters. One of the colums is a Date type, and when I am changing the culture in order to translate the application, the filter is correctly translated. However, if I click on the calendar icon to select the date, that component is not being translated. Is this a bug?

Kind regards,

Román.

I have a RadGridView and I have implemented IDataErrorInfo on the view model.    Unfortunately, when the user types in something invalid and an error appears, the message is cut off.  I want to style it -- style... something -- so that the full error message will show.  But I don't know what property to set or what to style

Hi,

When using RadGridView ExportAndShow method (GridViewExportFormat = Csv or Txt), the first data row is inserted next to column headers, it's missing a carriage return.

ResultGrid.ExportAndShow(GridViewExportFormat.Csv, "fileName.txt", true);

I'm using Telerik.UI.for.Wpf.80.Xaml 2025.4.1321

We have recently updated our Telerik libraries to v2012.3.1129.40. While our experience with this is been good in general there seems to be a bug with the way GridViewColumnGroups and Frozen columns interact. One of our screens contains a RadGridView with 3 frozen columns and a lot (>50) of columns that are divided into about 12 groups. Because of the number of columns the users requested we allow them to show/hide the columns on a group by group basis which we have done (we have check boxes to control the visibility of the different groups). This worked fine prior to the upgrade but no longer seems to work correctly.

We can show/hide the groups (by showing/hiding the child columns causing the parent groups to show/hide) as before but if we show a group (either for the first time or after it has been previously hidden) it does not  function correctly when the grid is scrolled horizontally. Instead of scrolling "under" the frozen columns as expected the group header remains stuck against the frozen column while the column headers and the data rows continue to scroll as expected. If I remove the frozen columns the horizontal scrolling works as expected.

This bug means that we are unable to have Frozen columns which is a critical in a grid with so many columns

Thanks,

Hi, I'm working on a project that uses Telerik  version 2016.1.314.45. Right now we're trying to more widely implement Search As You Type. I see in the documentation that there is some sort of object named SearchStateManager, that you can use in order to modify the search. I cannot find the object in my version. But i can find an answer on a stackoverflow post from 2016/09/07, with an image, that seems to have implemented IsSearchWithAccentEnabled.

When was the feature introduced. I was hoping that in my version could implement similar features as seen on the aforementioned image

Good morning,
I can't figure out how to change the GridView style in the RadMultiColumnComboBox WPF. I'd like to change the text in the column header, for example, or the alternating columns, but I can't figure out how. I have the 2022 version of Telerik 2022 R3 SP1. I hadn't had any problems with WinForm, but I'm having some difficulty with WPF. Can someone tell me how to do it?
Thanks

Is it possible to set the WPF RadGridView FilteringMode="FilterRow" so that the search updates in real time as you type the text, like it was in winform?

And also that it uses the "contains" mode by default without having to select it from the menu every time, like it was in winform?

Thanks

Hi,

Is this large number of PriorityItem<DispatcherOperatio> which is more than 373K normal in RadGridView? Why is this happening? Is there anyway to stop the propertyChangedCheckerTimer created by default in RadgridView?

Version: 2017.2.503.45

 

Hi,

is it possible to set the search field below the columns in the WPF grid like it was in the WinForm grid? Without clicking the filter button?
