When trying to use the new row I get Binding Errors when using the Office2019 theme and the new row is a visually empty. 
The Binding errors are:

• System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.GridViewDataControl', AncestorLevel='1''. BindingExpression:Path=GridViewNewRowContent; DataItem=null; target element is 'ContentPresenter' (Name=''); target property is 'Content' (type 'Object')
• System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.GridViewDataControl', AncestorLevel='1''. BindingExpression:Path=GridViewNewRowContentTemplate; DataItem=null; target element is 'ContentPresenter' (Name=''); target property is 'ContentTemplate' (type 'DataTemplate')

When using the Office2013 theme everything works as expected. If I disable row virtualization the Office2019 theme works as expected. 
What do I need to change to get the Office2019 theme working with vivirtualization ?

When trying to use the new row with the Office2019 theme, I get binding errors and the new row is visually an empty row. Using Office2013 works as expected. The errors shown are:

I am using version 2025.1.211. Disabling row virtualization makes it work with the Office2019 theme. What do I need to do to get it to work with the Office2019 theme and virtualization?

Hello,

I use the PrintPreview Control with the PrintAndExportExtensions.cs as shown in the GridView/PrintPreviewWithSpreadsheet example, which works very nicely.

Now I would like to suppress the Windows PrintDialog which is shown after clicking the print button, since it blocks the UI and does not show the parameters correctly (instead of the previously in the PrintPreview Control selected parameters the dafault values are displayed but it seems the correct values are pased to the printer).

For selecting the printer, I would like to add a ComboBox to my view. Is there a way to pass the selected printer as a string or with PrintSettings to the RadSheet or the PrintPreview Control/ViewModel and suppress the Windows PrintDialog?

I also had a look at the example from this post: https://www.telerik.com/forums/printing-and-print-previewing-my-grid#r3qTgvsrCkiSP_PxTMubzA

but the PrintSettings in the CreateDocument method aren't used.

Any help would be appreciated.

 

Best regards

Hi,

I can see this is a little bit of a recurring question in the forums, but what is the latest best way of tracking user column width changes in RadVirtualGrid and RadGridView? We're interested in making the format of decimals displayed in the cells respond to the available width.

We're currently using 2025.1.211 but could upgrade if that helped.

Thanks in advance,

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
