Hello there,

I'm quite unfamiliar with the Infragistics components but the WebHierarchicalDataGrid is exactly what I have to use for a certain application.

Here's the thing:

- I have a DataSet with multiple DataTables inside, and they are connected to each other with the DataRelation property

- When I bind the connected DataSet to the WebHierarchicalDataGrid , everything works fine and I'm able to expand the rows

But here are my problems:

- I don't want do display the same data in the WebHierachicalDataGrid as in the DataSet,  I need additional checkbox columns and I have to remove columns. At the moment, it works fine for the "root" parent rows - I just manipulate the Grid in the .aspx file, set autogeneratecolumns = false and added the columns I need manually as BoundedFields and TemplateFields in the <columns> section. In the code-behind file, I iterate through the Grid and set the checkboxes as checked based on Data in the DataTable. The best way would be, of course, to generate checkboxes automatically based on a boolean value, but I haven't figured out yet how that works.

- What worked fine for my parent rows, doesn't work out for my children rows. I'm able to change the columns of the children by manipulating them in the handler-method of the RowIslandCreated()-event. Example:

            boundField = new BoundDataField(true);
            boundField.Key = "DURATION";
            boundField.Header.Text = "Duration";
            boundField.DataFieldName = "DURATION";
            contgrid.Columns.Add(boundField);

But how can I add a checkbox-column ? When I want to use the templatedatafield for that purpose, I have to provide a own checkbox-class for its ItemTemplate property. Isn't there a more elegant way to add a checkbox column ?

I would really appreciate if you could help me, it's really important.

Best regards,

Michael
