RadGridView filter displays date in wrong format

[Benedikt]

I have the problem, that the filter in the Telerik RadGridView has a wrong formatting for date fields. In the grid it self they are drawn correctly. I use the format: dd.mm.yyyy

 Please take a look at the attached screenshot.

 I set the column culture like this:

GridViewBoundColumnBase column = new GridViewDataColumn();
column.Language = System.Windows.Markup.XmlLanguage.GetLanguage("de-DE");
this.IsLocalizationLanguageRespected = true; // this is the instance of the RadGridView

Thank you!

Hi Benedikt,

You can try setting the date time format of the column through the DataFormatString property. You can find more information regarding it on the following documentation page -Data Formatting. Once you apply it the filter should inherit the value of this property. I have tested this at my end and it works correctly with changing the different date formats. You can simply use the following code in your XAML:

<telerik:GridViewDataColumn  DataMemberBinding="{Binding DateEstablished}"
    Header="Date"
    DataFormatString="{}{0:dd.MM.yyyy}"/>
