DataGridView Add Row

[missshhhh]

Hi, I have DataGridView and I have a Add New Row Button and a Delete Row Button. What is the code to add a new row in the datagridview? Also the code to delete a row from the datagridview?

Note: I do not want to enable the AllowUserToAddRows and AllowUserToDeleteRows properties of the datagridview because I want to do it programatically.

Thanks!

Is your grid bound to a data source? If so then you should be adding and deleting rows in that data source, not the grid. If the grid is unbound then you call the Add and Remove methods of the grid's Rows collection.

Adding a row to datagridview with textBox columns

        Dim dgvRow As New DataGridViewRow
        Dim dgvCell As DataGridViewCell

        dgvCell = New DataGridViewTextBoxCell()
        dgvCell.Value = "anis"
        dgvRow.Cells.Add(dgvCell)

        dgvCell = New DataGridViewTextBoxCell()
        dgvCell.Value = "khan"
        dgvRow.Cells.Add(dgvCell)

        DataGridView1.Rows.Add(dgvRow)

Remove and RemoveAt methods of datagridview can be used to remove a row

  DataGridView1.Rows.RemoveAt(index)

Adding a row to the dataTable if datagridview is bound to it

        Dim row As DataRow = dt.NewRow
        row("Col1") = "anis"
        row("Col2") = "khan"
        dt.Rows.Add(row)

Similarly to remove row from datatable use remove and removeAt

dt.Rows.RemoveAt(index)

DataGridView1.ColumnCount = 4
looks like the kind of syntax that maybe useful to you.

I tried that code and following error message came up: "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."

I use VB 2009 express am i doing something wrong?
I am a complete amateur, if you did not understood that yet.

if you have a databound grid, you should add a row to datasource to see an extra row in the grid.
If you want a different kind of row (say a totals row) you should look for FooterRow...

Dear aniskhan

when you talk about datagridview is bounded , I try your code :

Dim row As DataRow = dt.NewRow
row("Col1") = "anis"
row("Col2") = "khan"
dt.Rows.Add(row)

But it does not work , can you explain what you mean by dt

actully it's give mistake in " dt.NewRow " & " dt.Rows.Add(row) "

You realize the post you are asking about is 4 years old. You may not get a response from the poster.

However if you look at the code it is pretty clear that dt is the datatable that the grid is bound to.
