Hi Mehrdad,

Thanks for using Syncfusion Products.

By default we validate the formula expressions internally. We don't have any method to perform the validation explicitly. However You can achieve your requirement by handling CurrentCellEditingComplete event as follows:

Code Snippet [C#]

this.grid.CurrentCellEditingComplete += new Syncfusion.Windows.ComponentModel.GridRoutedEventHandler(grid_CurrentCellEditingComplete);

void grid_CurrentCellEditingComplete(object sender, Syncfusion.Windows.ComponentModel.SyncfusionRoutedEventArgs args)
{
int row = this.grid.CurrentCell.RowIndex;
int col = this.grid.CurrentCell.ColumnIndex;

if (this.grid.Model[row, col].Text == this.grid.Model[row, col].FormattedText)
{
MessageBox.Show("Error Message");
}
}

We have prepare a sample based on this, please find the sample from the following location.

Please let us know if this helps.

Regards,
Manikandan
