To achieve this requirement, you can extract and modify the GridViewSearchPanelTemplate located in the Telerik.Windows.Controls.GridView.xaml file.
In case you don't want to extract the control template you can use Visual Tree Helpers. You could subscribe to the Loaded event of the RadGridView and in the C# code you can take the SearchPanel TextBox with x:Name="PART_SearchAsYouTypeTextBox". After taking the TextBox you can change the Background and Foreground properties to your desired color.
Hello Dan,
To achieve this requirement, you can extract and modify the GridViewSearchPanelTemplate located in the Telerik.Windows.Controls.GridView.xaml file.
In case you don't want to extract the control template you can use Visual Tree Helpers. You could subscribe to the Loaded event of the RadGridView and in the C# code you can take the SearchPanel TextBox with x:Name="PART_SearchAsYouTypeTextBox". After taking the TextBox you can change the Background and Foreground properties to your desired color.
private void gridView_Loaded(object sender, RoutedEventArgs e) { var searchTextBox = this.gridView.ChildrenOfType<TextBox>().FirstOrDefault(x => x.Name == "PART_SearchAsYouTypeTextBox"); searchTextBox.Background = Brushes.Bisque; searchTextBox.Foreground = Brushes.HotPink; }For your convenience I prepared a sample solution where this logic is implemented.
