Re: GRIDVIEW color and size

["Mayost Sharon" <sharon@xxxxxxxxx>]

Hello

You say this:
Public Sub GridView1_Data(Row As Integer, Column As Integer)
   GridView1.Rows[Row].Text = " "
End

But this causes two problems:
1. If there are many records for example (500000) it does not change the width of the column header because it calculates the size of the width of the column header according to the size that "500000" occupies

2. It causes all the time to enter the Data event endlessly

Thanks
