Handle errorstates in DataTable

[Markus Kraft]

Hi,
my validationfactory provides me a defined table with rows- and columnsproperty "hasErrors".

if(ValidationDataDataSet.Tables[0].HasErrors == true)
{
errorRowArray = ValidationDataDataSet.Tables[0].GetErrors();
errorColumnArray = errorRowArray[0].GetColumnsInError();
}

Is it possible to highlight the cells with errorstate == true (automatically)in griddataboundgrid ?

Because it's absolutly complicated to manage errorcells and mark them in the GDBG.

greetings markus

You will have to handle an event, and in your handler, given a row and column, determine whether that row and column are in error or not.

A couple of events you could use for this include PrepareViewStyleInfo or Model.QueryCellInfo.

private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
	if(e.ColIndex > 0 && e.RowIndex > 0)
	{
		if( e_RowIndex_and_e_ColIndex_in_error )
			e.Style.BackColor = Color.Red;
	}
}

You may have to do some extra work as your error provider does not expose a method that returns whether a particular row and column is in error, and this is teh information you need to use these events.
