Hi,

I'm trying to bind an IDataReader to a GridView. I'm using TypedListDAO.GetAsDataReader. Problem is, I need to create a SortExpression based the string name of the (since that's what I'll get from the GridView_Sorting event). I can't find how ot do this, is it possible?

Thanks in advance,

Chris Moseley

Just set the SortExpression property in the column declaration in the aspx page to the corresponfing field name.

Sorry, my original post wasn't clear (even to me, as it seems I forgot how to speak English during some of it).

I have no problem getting hold of the string representation of the field name from the GridView, the problem I'm having is in constructing the ISortExpression in my code. I need to do something like this:

protected void SortGrid(string sortFieldName)
{
    ....
    SortExpression sorter = new SortExpression(new SortClause(fields[sortFieldName], SortOperator.Ascending))
    ....
    return dao.GetAsDataReader(...);
}

Try the following:

MyEntity myEntity = new MyEntity();
SortExpression sorter = new SortExpression(new SortClause(myEntity.Fields[sortFieldName], SortOperator.Ascending))

Good stuff, thanks.
