Cell colour disappears when scrolling/resizing

[Kristjan Einarsson]

Hi,
I'm changing the cell colour in the RowLoaded event via:

int reservedCells = 5;
if (item.Values[i].OriginalValueChanged)
{
         e.Row.Cells[i + reservedCells].Background = new SolidColorBrush(Color.FromRgb(255, 0, 0));
}

And it works fine until I scroll the grid or just re-size the window, is this a bug or am I doing the completely wrong ?

cheers
kristján.

Hello,

 RowLoaded is not the right place to style cells due to horizontal virtualization. Please use CellStyleSelector - you can check our demos for more info.

Hi, thanks I'll take a closer look to the demo but I'm doing all of the binding in codebehind, haven't found any good examples

cheers :)

do you have any examples where you do this in code behind that you can point to, I'm using dynamic columns for the grid and I have not found any.

Best regards

Hello Kristjan Einarsson,

Once you define the styles in the Resources section:

<Window.Resources>
   <my:NumberStyle x:Key="numberStyle">

     <my:NumberStyle.BigNumberStyle>

       <Style TargetType="telerik:GridViewCell">

          <Setter Property="Background" Value="HotPink"/>

          <Setter Property="Foreground" Value="White" />                 

        </Style>

      </my:NumberStyle.BigNumberStyle>

      <my:NumberStyle.SmallNumberStyle>

         <Style TargetType="telerik:GridViewCell">

           <Setter Property="Background" Value="Yellow" />

           <Setter Property="Foreground" Value="Black" />

          </Style>

      </my:NumberStyle.SmallNumberStyle>

</my:NumberStyle>      

</Window.Resources>

You may set the CellStyleSelector for a column like follows:

this.playersGrid.Columns[1].CellStyleSelector = (StyleSelector)this.Resources["numberStyle"];
