validate string in ggc

I am using syncfusion ggc 5.2. I want that if user enters a string which is more than 1000 characters the cell should show a error with an error message(error message only when user points to error symbol of cell).
I will be v thankfull if anyone could help me in this.

Hi Prabhjeet,

To validate the grid cell string, you need to handle the TableControlCurrentCellValidateString and set the e.Inner.Cancel to true for invalid text. Below are the codes:

void gridGroupingControl1_TableControlCurrentCellValidateString(object sender, GridTableControlCurrentCellValidateStringEventArgs e)
{
Console.WriteLine(e.TableControl.CurrentCell.Renderer.ControlText.Length);
if( e.TableControl.CurrentCell.Renderer.ControlText.Length > 10 )
{
e.Inner.Cancel = true;
FieldDescriptor fd = e.TableControl.Table.CurrentRecordManager.CurrentField;
CurrentRecordProperty prop = e.TableControl.Table.CurrentRecordManager.Properties[ fd ];
prop.Exception = new Exception( "Invalid Text"); //Error Message in a Cell;
MessageBox.Show("Invalid Text"); //Poup Error Message
}

}

Best regards,
