How to limit the characters of a field in gridview?

hi guys

i list the project descriptions on a field in my gridview, but some of them are too long. i want to limit them like 20 characters of 50 chars can be seen by the user. then pressing a button entire description will be displayed.

how can i do that?

waiting your answers.. thanks..

Are you using Labels? Texboxes?
In any case, I believe that if you do AutoSize = false (a property) the controls won't change size no matter what the Text is. So just define a size and the rest of the characters wont be displayed.
Then by pressing a button either have them increase in size or do AutoSize = true (and maybe also do Text += "" so the autosize takes effect)

thanks for your reply C_ntua but i could not find any property of gridview. i m using C# with asp.net, may be it is the reason.

i find a way that helped me.

it is like that

Code:

protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ViewState["description"] = e.Row.Cells[3].Text;
            if (e.Row.Cells[3].Text.Length >= 30)
            {
                e.Row.Cells[3].Text = e.Row.Cells[3].Text.Substring(0, 30) + "...";
                e.Row.Cells[3].ToolTip = ViewState["description"].ToString();
            }
        }
    }
