get cell value within gridview

I have a gridview that has a button in the last cell of each row. I want to get the text from cell 1 for that row the button was clicked on.

So if my gridview looks like this:

N-12 BMW [select]
N-35 Mercedes [select]

if my user clicks row 2, I want to see Mercedes, How can I do that?

I have a buttonClick event for my select button, I'm trying to pull the values using the DataKeyName, but I keep getting 'object reference not set to an instance of an object.

here is what i'm trying

select_Click()
{
string make = grid1.SelectedD ataKey.Values["CarMake"].toString();

}

any suggestions on how I can get the cell 1 text for the selected row within my Select_Click()?

Try using the GridView.Select edIndex value to point to the selected
row.
Then use the GridView1.Rows[SelectedIndex].Cells[1].Text to get the
value inside the cell.

I hope that helps!

I tried that and it gave me this error:

Index was out of range. Must be non-negative and less than the size
of the collection. Parameter name: index

If you get an error "Object instance not set..." it's because the
GridView hasn't been created yet. Try implementing your logic in the
GridView1_DataB ound(..) event. That way you are certain that the
GridView exists.

On this button, another developer setup an CommandArgument and is getting a
value that way within this same SendSales_Click (), is there a way to add
another value to that CommandArgument so it's passing 2 instead of 1 value?
If I put this in the grid_databound method, how would that work in passing
the value to the button when the user clicks it?
The Grid is already bound, the values are already there in the grid, I just
want the value from cell[1], when I click the button.

??? The OP is trying to get the value of one of the GridView's cells by
clicking a button on the GridView - he wouldn't even see the button if the
GridView hadn't been created yet...

Hmm - OK...

Set a breakpoint on the first line of the click even and run the code again

1) Does the code jump into the correct method?

2) Assuming it does, in the Immediate window write grid1 and press Enter -
do you see the properties of your GridView?

3) Assuming you do, in the Immediate window write grid1.SelectedR ow and
press Enter - what do you see...?
