GridView error

[Guest]

Hi Guys,

I have a link button in TemplateField in a gridview called
"transactionListGridView" and when tying to run this:
protected void transactionListGridView_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if (e.CommandName=="select")
{

string transactionID =
transactionListGridView.SelectedRow.Cells[1].Text;
messageLabel.Visible = true;
messageLabel.Text = xx;
}
}

it gives me this error message: "Object reference not set to an instance of
an object" do U know what could be the problem!!?


Cheers Guys.

What line throws the exception?

Its probably that the Row Selection hasnt taken place yet so
transactionListGridView.SelectedRow is null. You will probably need to get
the row index from the event args and select the row from the rows collection.

Hi,

it's this line that's raised the error "string transactionID =
transactionListGridView.SelectedRow.Cells[1].Text;"
could U explain to me what U denoted by getting the row index from the event
args!!?
What I'm trying to do is getting the Value of a specific cell when a row is
selected

Its probably that the Row Selection hasnt taken place yet so
transactionListGridView.SelectedRow is null. You will probably need to get
