So, once more:
c# - winform - VS 2010 express I have two forms with a datagridview on each (frm01-dgv01 and frm02-dgv02) On the main form (frm01) i can select dgvRow, press Delete Key - and dgvRow will be deleted.
So, I go to the second form (buttonClick): - new frm02().Show();
But, when I press Delete Key - to delete dgvRow - nothing happend ! Delete Key doesn't function !
If I enter to CellEditMode - DeleteKey – works !
Both dgv has AllowUserToDeleteRow = true.
No dgv is bounded.

private void btnDelete_Click(object sender, EventArgs e)
{
DataTable ret = new DataTable();//dataGridView1.DataSource as DataTable;
//Identify Row of datatable. and remove it to identify use your logic.
string expression = "Date > #1/1/00#";
DataRow dr = ret.Select(expression).FirstOrDefault();
if (dr != null)
{
ret.Rows.Remove(dr);
}
}
no need to rebind datasource to datagrid view because it is reference type so changes are reflected automatically.
hope this answer.

DataTable dt = GetData();
dataGridView1.DataSource = dt;
private void btnDelete_Click(object sender, EventArgs e)
{
DataTable ret = dataGridView1.DataSource as DataTable;
//Identify Row of datatable. and remove it
// DataRow dr = ---
ret.Rows.Remove(dr);
}
Your removing datarow from datatable, Where are you removing row from datagridview or rebinding datagridview?

If you populate datagrid reading XML, so you can also do First read xml using Dataset.readXML method and this dataset assign to data grid.

To do this remove Item from data source.
Example : I f you use datatable to bind datagrid than when user press delete button Identify this record and delete from datasource means datatable.
DataTable dt = GetData();dataGridView1.DataSource = dt;
private void btnDelete_Click(object sender, EventArgs e)
{
DataTable ret = dataGridView1.DataSource as DataTable;
//Identify Row of datatable. and remove it
// DataRow dr = ---
ret.Rows.Remove(dr);
}
hope this help.
