Cannot find RowClickEventArgs in DevexpressGridView

Question

I'm a new to DevexpressGridView.

I have a Dev Grid in my webpage, and I want to handle the RowClick Event like:

private void GridView1_RowClick(object sender, RowClickEventArgs e)
{
    if(a row is selected)// how???
        Button1.Visible=true;
}

But when it has an error: "cannot resolve symbol RowClickEventArgs", this is first time I know about Devexpress. So I wonder if my RowClickEventArgs syntax is wrong??? I've tried to find the solution by searching google for many times, but I still cannot get the right thing.

Can you give me a right syntax???

And one more question, how can I check " is there any row selected ?"

Help!

Answer 1

So it would be like this:

private void GridView1_Click(object sender, EventArgs e)
{
    System.Data.DataRow row = GridView2.GetDataRow(GridView2.FocusedRowHandle);
    if(row[0].ToString() == "")
    {
          //YOUR LOGIC
    }

}

GridView2 is your main view.
