Hi

I have below GridView, which i in codebehind page databind with a dynamicly
created datatable.

This all works fine, but after the databind i still only have a column count
of 1 although the datatable adds another 4 columns to the gridview. This
represents a problem, since i would like to have the last column properties
change on the fly and i cannot access the properties of any column besides
the on definded below. None of the databound columns created by the DataBind
method can be accessed..

How can i access these columns??

Can you try this:

sampleGridView.Rows(0).Cells.Count?

You could place this in Prerender to get the count.

I know the count of cells and it's correct and as expected in regard to the
SqlDataSource.Select command... What i need is a way to dynamicly determin
if i wan't to show a specific column of the data bound from the
SqlDataSource.

If for some reason i dont want to see the 3rd column, i want to do a
..visible = false; to the property of that column. I cannot do that, but i
can do it the individuel rows 3rd cell (Cells[3]). This leaves the header
row visible and indicates to the user that data is invisible.

Whar i don't understand is, why the databound gridview, after the dataBind,
cannot return a correct column.count but the individual rows of the same
gridview can... I don't see the reason for this and think there must be some
hack to do it...
