Hello,

I want to change the text-color of one column of my GridDataControl, if a property in the row-"object" (ItemsSource) is a specific value.

For example:

I bind a list of objects with the following properties to the GridDataControl:
- ID
- Request
- IsImportant

And now I want to set the text-color of the ID to red if the request is important.


Thank you very much,
Peter

Hi Peter,

Thanks for using Syncfusion Products.


You can achieve your requirement by handling QueryCellInfo event as follows:

Code snippet [C#]:

this.grid.Model.QueryCellInfo += new GridQueryCellInfoEventHandler(Model_QueryCellInfo);

void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
if (e.Style.ColumnIndex == 2)
{
bool? chk = e.Style.CellValue as bool?;
if (chk == true)
{
Console.WriteLine(e.Style.CellValue.ToString());
this.grid.Model[e.Style.RowIndex, 0].Foreground = Brushes.Red;
}
}
}

We have prepared a sample based on this and you can find the sample under the following location:

Please let us know if this helps.

Regards,
Manikandan

Hello,

Thank you but the property which decides if the text should be red or not is not the property for the current cell. It's another property which is not a "VisibileColumn"..

Thank you!

Hi Peter,

Sorry for the Inconvenience caused.
You can achieve your requirement by applying conditional formatting as follows.

Thank you very much! It works very well.

But I have a little problem: I only change the Foreground-property. Now if I select a row, this foreground will be overwritten.
