            int id=Convert.ToInt32(deptno_txt.Text);
            foreach (DataRow dr in ds.Tables[0].Rows)
           {
               if (id == 101)
               {
                    ds.Tables[0].Rows[0].Delete();
                }
              else if (id == 102)
               {
                    ds.Tables[0].Rows[1].Delete();
               }
                else
                    ds.Tables[0].Rows[2].Delete();
            }

I'm trying in this fashion. It's working but if I have 1000 records then it becomes difficult. So I want simple code that deletes records in dataset so that I can update to database using commandbuilder.

Hey then why are you using for loop in your code.
Just using
ds.Tables[0].Row[0].Delete();

Don't write your comment in answer section.

Hi vikky423,

C#

private void btndelete_Click(object sender, RoutedEventArgs e)
        {
            for(int nRow=0;nRow<=ds.Tables[0].Rows.Count;nRow++)
            {
               if(ds.Tables[0].Rows[0]["Id"].ToString().Equals(txtbox.Text))
                {
                  ds.Tables[0].Rows[nRow].Delete();
                  ds.Tables[0].AcceptChanges();
                  --nRow;  // If Id comes multiple times in Dataset.
                  break;  // else use break it come out from loop.
                } 
           
            } 
        }

Here Id --> is your Column Name
<= --> use only less than not less than equal

Cheers :)
