Two Part GridView Question

[E L Golpe]

ONE I have a ButtonField column in a GridView like so:

asp:ButtonField DataTextField="Day" HeaderText="Date" CommandName="Detail"

It lists the dates.. like 2,3,4,5,6 and so on in each GridRow. I want to fetch the date as an integer. I tried:

int nDay = Convert.ToInt32(gvStats.SelectedRow.Cells[0].Text);

but the SelectedRow is null. How do I go about it? ie:What object holds the correct value? TWO In my former DataGrid I have:

if (dgClicks.DataKeys[dgItem.DataSetIndex] != System.DBNull.Value)

can this be written as

if (gvClick.DataKeys[gvRow.DataSetIndex].Value != System.DBNull.Value)

Will it work correctly? Is this a valid conditional? ANY help on either would be GREATLY appreciated. Thanks Practice sesquipedalianism! ;)

Question 1: The SelectedRow property of the GridView control is null until you make a Select command, so you may replace the command name "Detail" with the "Select". If you want to use "Detail" as the command name, you can simply convert the ButtonField into a TemplateField with a Button so that you can pass the Day value in the CommandArgument property. You may also keep using the ButtonField with the Day value passed along with the CommandName. Question 2: The GridViewRow class does not have the DataSetIndex property, but it has a similar one named DataItemIndex, so it can rewritten like this:

if (gvClick.DataKeys[gvRow.DataItemIndex].Value != System.DBNull.Value)
