Answer» Can someone please help me on this problem. I am trying to send the updated changes to the sql database when I remove a row. I use the delete method to delete the numbered row and then use the upadte command to update the changes. However, when I reload the PROGRAM all the rows are still showing again. Below is the current code I am using for forms 1 and 2. This has been giving me a headache for awhile now and any further help would be appreciated:
Code: [Select] //form1
private void UpdateSavebtn_Click_1(object sender, System.EventArgs e) { Mcon.Open(); UpdateVal = 1; if (UpdateVal == 0) { CurCol = dataGrid1.CurrentCell.ColumnNumber; CurRow = dataGrid1.CurrentCell.RowNumber; CellValue = dataGrid1[CurRow, CurCol].ToString(); MessageBox.Show(CellValue.ToString());
if (CellValue == "") {
MessageBox.Show("No FIELDS can be Blank - update failed"); Movset1.RejectChanges(); ImageMain(); CurRow = -1; CurCol = -1;
Mcon.Close(); return;
} CellValue = dataGrid1[CurRow, CurCol].ToString(); CurRow = -1; CurCol = -1; }
MovAdapt.UpdateCommand = cb.GetUpdateCommand(); MovAdapt.Update(Movset1.Tables[0]); Movset1.AcceptChanges();
MessageBox.Show("New MOVIE added");
Mcon.Close(); UpdateVal = 0;
dataGrid1.RowHeadersVisible = true; }
Code: [Select] private void button1_Click(object sender, EventArgs e) { if (textBox1.Text == "") { MessageBox.Show(" Please enter a title to be DELETED "); return; }
DSMethod(); DV2 = new DataView(ds2.Tables[0]); F1.dataGrid1.DataSource = Dv2; Dv2.RowFilter = "Title ='" + textBox1.Text + "'";
if (Dv2.Count < 1) { MessageBox.Show("Movie does not exist in MovieBase, please try again"); return; } else { int rownum = (F1.dataGrid1.CurrentCell.RowNumber); Dv2.Delete(rownum);
ds2.AcceptChanges(); //MovAdapt.UpdateCommand = cb.GetUpdateCommand(); //MovAdapt.Update(Movset1.Tables[0]); this.Hide(); //Dv2.Table.Rows.Remove(Dv2.Table.Rows.current) MessageBox.Show("Movie has been deleted"); } Try updating the whole DataSet, as in
Code: [Select] MovAdapt.Update(Movset1);
