Hi Mauricio:

Here is a way to limit the length of input on a datagrid column.
The column you input the data in is actually a textbox. We know in textbox
we can limit its length by its property MaxLength.
So you can use the textbox in data grid in the same way. Notice that you
can use a "DataGridTextboxColumn" object which has a property "Textbox".

Here are the detail steps:

First, create a DataGridColumnStyle and add a DataGridTextBoxColumn object:

1. We create a corresponding data grid table styles for this data table,
you may add the table style in DataGridTableStyle Collection Editor, make
sure the MappingName is set to the correct table name.

2. We need define the column styles for the table style; you may add the
column styles in GridColumnStyles property

3. Now you may set the MaxLength for a certain DataGridTextboxColumn like

dataGridTextBoxColumn1.TextBox.MaxLength = 6;


Does this solve your problem? I'd like to follow up with you on this issue,
if you still have problem on it, please be free to reply this thread to let
me know.
