How to get Devexpress XtraGrid control selected row
0
I've a devexpress XtraGrid Control. But, I couldn't get the ID of a by default selected row when the winform loads. I know how to get it when the user clicks on the grid.
Here is the code snapshot:
private void Form1_Load(object sender, EventArgs e)
{
grid1.DataSource = bindData(DataClassesDataContext.Table1.ToList());
ID = Convert.ToInt32(gridView.GetRowCellValue(gridView.FocusedRowHandle, "ID"));
XtraMessageBox.Show(ID.ToString());
}
public BindingSource bindData(object obj)
{
BindingSource ctBinding;
try
{
ctBinding = new BindingSource();
ctBinding.DataSource = obj;
return ctBinding;
}
catch (Exception ex)
{
XtraMessageBox.Show(ex.Message, "Database Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
return null;
}
}

Could you specify the problem you are having. I don't think I understand what you need.

The problem is that every time the form loads it throws "Object reference not set to an instance of an object." When i look deeper into the code, the problem lies on getting the focused row (by default) value. It returns 0 (for the ID) even though there are too many rows in the list. It works fine when i click on the rows though. But, what I want it to get the ID when the form loads

you should really add that to your question. If it returns 0, you are looking at theRowHandle, not the row value. Try moving your code to aform_Shownevent instad ofform_Loadevent

you should really add that to your question. If it returns 0, you are looking at the
RowHandle, not the row value. Try moving your code to a form_Shown event instad of form_Load event– Jens Kloster

If I understand you correctly, you need something like this:
private void Form1_Shown(object sender, EventArgs e)
{
grid1.DataSource = bindData(DataClassesDataContext.Table1.ToList());
var item = gridView.GetFocusedRow() as YourDataType
if(item != null)
{
ID = item.ID;
XtraMessageBox.Show(ID.ToString());
}
}
assuming what your bindData returns a typed collection of some kind.
** Update **
Moving the code to form_Shown seemed to do the trick.
