I have a gridview column item that i want to not make visible if the
bound data in that cell is less than a value in a textbox.
However, I notice at the time my code checks a function that I call
from the visible property of the gridview itemtemplate, the textbox is
always blank.
I tried setting the textbox in the prerender, but I suspect the
gridview is built much earlier in another event.. like items created.
Whats the best way to attack this?
Also, and a question I can't believe I'm asking.. what's the preferred
way to store information in a codebehind variable so that's a
available across all subs, functions and events? For example, if I
want to have something in a variable I set in the prerender, how do I
make that available in Page load sub?
PreRender event fires after Load, so it won't help if you set something in
PreRender. Otherwise, if you just declare a field or a property in your page
class it will be visible by all other members.

Sounds like you can use a RowDataBound event handler like so (very
sketchy code, but you get the idea.)
protected void MyGridView_RowDataBound(object s,
GridViewRowEventArgs e)
{
// Hide the header of the leftmost column.
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Visible = false;
}
// Hide the leftmost column of the data row.
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[0].Visible = false;
}
}
