Hi,
I created a form in which I added a dataGridView and four textBoxes and Two Buttons (Add,Delete).
My problem is when i select a Row in dataGridView and then Click on Delete button it remove that row from dataGridView but it doesn't effect on database.
My code is :-

C#

//In form load event
DC.SelectSta("select proName as Name,proComp as Company,proQty as Qty,proUnit as Unit from orderList", "orderList");
            dataGridView1.DataSource = DC.dataSet;
            dataGridView1.DataMember = "orderList";

//delete Button click event
try
{
    DialogResult dr = MessageBox.Show("Do You want to delete the product details?", "Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (dr == DialogResult.Yes)
    {
        dataGridView1.Rows.RemoveAt(dataGridView1.CurrentRow.Index);
        DC.adpt.Update(DC.dataSet, "orderList");
    }
}
catch
{ }

Thanks In advance....

Try this,

C#

if (dr == DialogResult.Yes)
    {
DC.dataSet.Tables["orderList"].Rows[CurrentRow.Index].Delete();
DC.dataSet.AcceptChanges();
         dataGridView1.DataSource = DC.dataSet;
            dataGridView1.DataMember = "orderList";
dataGridView1.DataBind();
    }
