单击按钮时在数据网格视图中删除一行

Question

I have a form1 and form2 ..

form1 : I have a datagridview with a button column. When I click on the button cell for any row the corresponding row values will be transferred to form2. That was working fine.

Form 2 : by using setters and getters I have got the values from form1 and I represent the values in textboxes in form 2, and that was fine.

I have a checkbox in form 2. When I click on the check box, I need to remove the row in datagrid view in form 1 (whose row values are transferred to form 2 when I click on the button cell. That row will be deleted from the datagrid view in form1).

How do I fix this?

Answer 1

When you pass data from Form1 to Form2 , also pass the row index. It will help you delete the row easily.

Either mark the DataGridView of Form1 public or pass it as a constructor parameter to Form2 and then call DataGridView1.Rows.RemoveAt(rowIndex); to delete row at the index specified by rowIndex .

Answer 2

If you know how to delete a record from a grid view from the same form, this is easy.

You can follow the same way as in the answer of Stack Overflow question Updating the gridview in one form .

As the event arguments you can pass the record ID.

You can use the RemoveAt method for deleting a record from the grid view.

DataGridView1.Rows.RemoveAt(deleteIndex);

But if you share the datasource and remove it from form 2 you need to bind data again to remove from the grid. (See How to: Implement Property Change Notification on how to update the gridview.)

If you delete it on the form1 and directly from the gridview, you don't need to bind it again.

Answer 3

foreach (DataGridViewRow item in this.dataGridView1.SelectedRows)
{
  dataGridView1.Rows.RemoveAt(item.Index);
}
