Getting the selected row from dataGridView1

Question

I have a dataGridView1 on my Wondows Form Application. I have populated the dataGridView1 with a list of strings. This all works great. But...

I need to be able to grab the row the user is selected on and I can't seem to do it. My code just gives me an error, written below.

I have copied GridViewRow form the msdn site.

private void editButton_Click(object sender, EventArgs e) {
        GridViewRow row =  dataGridView1.SelectedRow;

        //This is what I have been using before with a list box.
        if (itemList.SelectedIndex >= 0) {
            int newInt = itemList.SelectedIndex;
            Form form = new NewItemW(selectedFolder, this, items[newInt], WindowEnum.ItemEdit);
            form.Show();
        }
    }

I have tried this but I am getting the error: "The type or namespace 'GridViewRow' could not be found."

My basic question is how do I get this to work?

Answer 1

Assuming you are using a Winforms DataGridView you should do it like this:

private void editButton_Click(object sender, EventArgs e) 
{
   if (DataGridView1.SelectedRows.Count > 0)
   {
      DataGridViewRow row =  dataGridView1.SelectedRows[0];
      if (itemList.SelectedIndex >= 0) 
      {
         int newInt = itemList.SelectedIndex;
         Form form = new NewItemW(
                         selectedFolder, this, items[newInt], WindowEnum.ItemEdit);
         form.Show();
      }
   }
}

By copying from that link you have mixed the WPF Controls and their code with Winforms. Often folks mix up just the names DataGridView vs GridViewRow , but you have also copied the wong Property SelectedRow . Instead use the first element of the SelectedRows collection. Also always check or else the array acess will crash..

Answer 2

you are using the web control System.Web.UI.WebControls.WebControl.GridViewRow, it must be hosted in a web page. For windows form use the System.Windows.Forms.DataGridViewRow control.
