GridView question

[Mike P]

I have a grid view with a button field that when clicked I want it to
redirect to another page, passing the primary key of the row with it.
This was a pretty easy thing to do with the DataGrid, but it is so far
proving a pain with the GridView.

Here is my button :

<asp:ButtonField ButtonType="Image" ImageUrl="~/Images/btnDetails.jpg"
CommandName="OpportunityDetails" />

In the GridView DataKeyNames is set like this :

DataKeyNames="OpportunityID"

And I am trying to redirect using this code :

protected void GridView1_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if (e.CommandName == "OpportunityDetails")
{
//get PK (opportunityID)
int intOppID = Convert.ToInt32(e.CommandArgument);

Response.Redirect("OpportunityDetails.aspx?oppid=" +
intOppID);
}
}

Instead of the PrimaryKey being passed, I just get the GridView index
passed (for the first row 0 is passed, for the second row 1 is passed
etc).

There must be a simple solution to this, I'm hoping somebody can tell me
what it is!

instead of the datakeynames you might want to use selected
gridview1.selectedDataKey or selectedValue

What is the syntax for getting the SelectedDataKey for the selected row?
