derive own controls from BoundField?

[Martin Bischoff]

[this is question about the ASP.NET 2.0 details view control]

When I add a row which is bound to a string field, the details view displays
a single-line text box control in edit mode. Often, I would like to have a
text area instead. I know that I can achieve this by converting the row to a
template row and add a textbox with TextMode="MultiLine". But it seems to me
that this is a very common need, and I don't like to edit every page/row
where I need the same functionlity.

Is it possible to derive my own controls (e.g. containing a text area) from
BoundField and use them in a details view? Are there any samples
demonstrating this?

Thanks for any help,
Martin

Hi Martin,

Welcome to ASPNET newsgroup.
Regarding on the question on creating a custom Field for DetailsView, it's
possible and in fact this is already available for asp.net 1.x DataGrid
control. For DataGrid, we can create our custom datagridcolumn through
create custom class derived from DataGridColumn and override the certain
methods. And for the GridView/DetailsView contorl in asp.net 2.0, all the
XXXFields are derived from the DataControlField:

#DataControlField

Also, here is a tech article in MSDN discussing on creating a custom
datagrid Column, you can get some ideas from it:
