DataGridView help

Experts,

I am new to development. I am using VS2008 and C#. I am I am trying to fill different controls and other things on my form based on the value of certain columns in the current row of a DataGridView control. For example one line of code is:
comboTech1.Text = wd_help_deskDataGridView.CurrentRow.Cells["help_tech"].Value.ToString();

My question is, what DGV event should I use to fire when a new row gets focus. I tried using RowEnter event but the CurrentRow value is not set when this event triggers. RowStateChanged also seems to have the same problem. The only event I've been somewhat successful with is RowPrePaint but this fires multiple times when the DGV populates each line and it does not seem very efficient. Is there an event I am not seeing or am I going about this wrong?

Thanks,
Chad

Try SelectionChanged Event

Thx for the quick response. But won't that event also fire if the user changes to a different cell in the same row? I only want it to take place if the row changes.

Thanks,

Hi kalittaair,

Use the RowEnter event -> http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rowenter.aspx

Wayne,

You'll notice my example uses the CurrentRow value. The CurrentRow value is not set on a RowEnter event. When RowEnter fires, the value of the CurrentRow is actually the row that just lost the focus, not the new one. If i use this event, how do I determine which row just got the focus?

Thanks,
Chad

wd_help_deskDataGridView.Rows(e.RowIndex)

I see. I use the RowEnter event but rather then use the CurrentRow value to find the new row I use e.Rowindex? I'll try that and report back. How would I pick out a specific column's value using that? In other words, can you re-write this line of code using the e.Rowindex:
comboTech1.Text = wd_help_deskDataGridView.CurrentRow.Cells["help_tech"].Value.ToString();

Thanks,
Chad

Thanks for the code, but I get:
"Non-invocable member 'System.Windows.Forms.DataGridView.Rows' cannot be used like a method."

As I was typing it, when I got to (e.RowIndex). Intellisense did not allow me to pick "Cells" so I figured it was going to bomb. Any ideas?

Sorry, that should have been like this....

    comboTech1.Text = wd_help_deskDataGridView.Rows[e.RowIndex].Cells["help_tech"].Value.ToString();
