Setting a cells style during edit...on row change clears style

[Chris]

I have a grid that we need to bold the text when the value changes...the code Im using is in the CellEditEnded event handler:

void GridView_CellEditEnded(object sender, GridViewCellEditEndedEventArgs)
{
if(e.NewData != e.OldData)
{
e.Cell.FontWeight = FontWeights.Bold;
}

} 

This works fine...BUT when I switch rows the style goes back to its original style. My use case requires that ALL changed values remain bolded.

How can I achieve this?

Thanks,
Ron

Hello Chris,


You may do something like the following:

private void RadGridView_CellEditEnded(object sender, Telerik.Windows.Controls.GridViewCellEditEndedEventArgs e)
       {
           if (e.NewData != e.OldData)
           {
               e.Cell.FontWeight = FontWeights.Bold;

           }
           e.Handled = true;
       }

Afterwards all changes for edited cells will remain, when you switch between the rows.

This doesn't appear to be the case when row and column virtualization is true (which we need because of the large amount of data we are displaying).

Hello,

Indeed, the approach previously suggested will not work correctly with a virtualized GridView.

The best approach would be to have a property of the bound Item indicating whether the bound property has changed. Then apply a CellStyleSelector for the column(s) similar to the example in this help article.

I hope this helps.
