I have GridView with several pages and I want to retrieve the row index of the second page.
I am getting this error for the below code that I tried.
Index was out of range.

here my code is:

C#

if (e.CommandName == "Go")
{
    int i = Convert.ToInt32 (e.CommandArgument);
    GridViewRow row = GridViewArtenVerp.Rows[i];
    // some code to retrieve cellvalues
}

Can someone help me?
Thanks in advance.

Did you check what is the value of i?

the value of i is 11, the gridview.pagesize = 10. if I navigate to the second page (next) and choise the second row I get the error

the commandarg of the Rowbutton is : CommandArgument='<%# DataBinder.Eval(Container, "DataItemIndex") %>'

Put a debug point on your code and check i. It seems to be a value for which no row exists.

Your command argument is the index in your datasource, not your gridview. If your page size in the gridview is 10 then the valid range of indices for the control will be between 0 and 9.
If you are trying to select the item with a command argument of 11, then you need to take the modulus of the the index and that will translate it to the correct gridview index. i.e. GridViewRow row = GridViewArtenVerp.Rows[i % 10]; (Note. I would add some validation around this. I never allow for calculations in an index field like I have shown here.)
