Grid view - Column

I am creating an application in asp.net..I used a grid view to show the datas .. By using the autogenerate columns

I bind the datas to the gridview.. Now i want to make a edit button at the end ..By clicking that the user can edit their details ...

But i need to count the number of columns in a row to make a pop up window to edit the details.. How to find out the number of columns in a autogenerated开发者_如何学C grid..Number of columns varies depend upon the user..So how to find the number of columns..

You will get the no of columns through like this

You can find,
How many columns are in gridview with

GridView1.Columns.Count

How many cells are in one row of gridview with

GridView1.Rows[..].Cells.Count
