Solution 1

It seems like the DataKeys collection is empty.

Try to change your code to something like:

C#

if (GridView1 != null && GridView1.DataKeys.Count > 1)
{
    Id = Convert.ToInt32(GridView1.DataKeys[1].Value);
}

Solution 2

Could you show your code on the page. verify whether you have set the DataKeyNames(for grridview) or not. you can get the DataKeys collection only if you set this property.

Solution 3

Id = Convert.ToInt32(GridView1.DataKeys[1].Value);

Here the Value of may be Empty..ie check instead 1 to 0.

Id = Convert.ToInt32(GridView1.DataKeys[0].Value);

Solution 4

Its a ArgumentOutOfRange exception which reads your given range is not exist with current control.

means GridView1.DataKeys[1] is not exist. check with the index you provide.
