Hi all, I want to create code to delete row in datagridview based on checkBox selection. I've managed added the checkBox Button using code below:
private void FormTampil_Load(object sender, EventArgs e)
{
DataGridViewCheckBoxColumn checkboxColumn = new DataGridViewCheckBoxColumn();
checkboxColumn.Width = 30;
checkboxColumn.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
dataGridView1.Columns.Insert(0, checkboxColumn);
// add checkbox header
Rectangle rect = dataGridView1.GetCellDisplayRectangle(0, -1, true);
// set checkbox header to center of header cell. +1 pixel to position correctly.
rect.X = rect.Location.X + (rect.Width / 4);
CheckBox checkboxHeader = new CheckBox();
checkboxHeader.Name = "checkboxHeader";
checkboxHeader.Size = new Size(18, 18);
checkboxHeader.Location = rect.Location;
checkboxHeader.CheckedChanged += new EventHandler(checkboxHeader_CheckedChanged);
dataGridView1.Controls.Add(checkboxHeader);
}
private void checkboxHeader_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i < dataGridView1.RowCount; i++)
{
dataGridView1[0, i].Value = ((CheckBox)dataGridView1.Controls.Find("checkboxHeader", true)[0]).Checked;
}
dataGridView1.EndEdit();
}
But I'm still confuse how to declare the code in "Delete" button, so if I select one or all the rows, the data selected will be deleted from datagridview also from database. I want to delete the data based no_simpan as primary key.
private void btnDelete_Click(object sender, EventArgs e)
{
//what code should I create here?
}
Pls someone help me...
Thanks in advance..
