I finally found a way to solve your (first) problem.

Because the HyperLinkColumn object doesn't exist when parsing the page, 

you have to reference it in another way. Here is an example in C# and VB



C#:



HyperLinkColumn hlcTemp;

hlcTemp = checked((HyperLinkColumn)list.Columns[0]);





VB:



Dim hlcTemp as HyperLinkColumn;

hlcTemp = CType(list.Columns[0], HyperLinkColumn);



I did not check the VB code, but it should work.

The trick is to explicit convert the first column of the datagrid to the 

hyperlinkcolumn type and reference that.

Then it is possible to acces all HyperLinkColumn attributes.



Good luck,



Ivo
