DataGridView problem

[mynkow]

Hi,

I have a dataGridView with textBoxColumn. I have an Enum type with 3 values. The property ValueType is set to the enum

dataGridViewTex tBoxColumn1.Val ueType = typeof( EnumType );

But when I enter a value that is not in the Enum I get an Error Window that tells me that I am not handled exception in System.Enum.Par se(...). How can I handle this exception ( where??? ).

The Exception

You would have to put a try/catch block around the insertion.

But you should read what you are saying.
You want the column to be of the enum values...but you are trying to insert a non-enum value.
That would be like having an int column and wondering why "jane doe" is not allowed to be inserted into it.

That is the point. I want to catch values that are not in the Enum.

Does this work?

try
{
EnumType mytest = (EnumType)SomeValue;
}
catch(Exception ee)
{
//didn't work
}

[mynkow]

No.

If this can help...

Have you tried any the events for the DataGridView object?

Possibly usefull events:
myDataGridView. CellParsing
myDataGridView. CellErrorTextCh anged
myDataGridView. CellErrorTextNe eded

When occurred this kind of exception the DataGridView calls "DataError" event where I can handle the Exception.

private void dataGridView1_DataError( object sender, DataGridViewDataErrorEventArgs e )
		{
			System.Diagnostics.Debug.WriteLine( e.Exception.Message );
		}

Hehe, you know I went looking for a DataError event and somehow managed to miss that exact one.
Good find.
