How to handle click event in Button Column in Datagridview?

Assuming for example DataGridView has columns as given below and its data bound items are of type PrimalPallet you can use solution given below.

private void dataGridView1_CellContentClick( object sender, DataGridViewCellEventArgs e )
{
    if ( e.RowIndex >= 0 )
    {
        if ( e.ColumnIndex == this.colDelete.Index )
        {
            var pallet = this.dataGridView1.Rows[ e.RowIndex ].DataBoundItem as PrimalPallet;
            this.DeletePalletByID( pallet.ID );
        }
        else if ( e.ColumnIndex == this.colEdit.Index )
        {
            var pallet = this.dataGridView1.Rows[ e.RowIndex ].DataBoundItem as PrimalPallet;
            // etc.
        }
    }
}

It's safer to access columns directly rather than using dataGridView1.Columns["MyColumnName"] and there is no need to parse sender to the DataGridView as it's not needed.

You can try this one, you wouldn't care much about the ordering of the columns.

private void TheGrid_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (TheGrid.Columns[e.ColumnIndex].HeaderText == "Edit")
    {
        // to do: edit actions here
        MessageBox.Show("Edit");
    }
}

For example for ClickCell Event in Windows Forms.

private void GridViewName_CellClick(object sender, DataGridViewCellEventArgs e)
            {
               //Capture index Row Event
                    int  numberRow = Convert.ToInt32(e.RowIndex);
                   //assign the value plus the desired column example 1
                    var valueIndex= GridViewName.Rows[numberRow ].Cells[1].Value;
                    MessageBox.Show("ID: " +valueIndex);
                }

You will add button column like this in your dataGridView

        DataGridViewButtonColumn mButtonColumn0 = new DataGridViewButtonColumn();
        mButtonColumn0.Name = "ColumnA";
        mButtonColumn0.Text = "ColumnA";


        if (dataGridView.Columns["ColumnA"] == null)
        {
            dataGridView.Columns.Insert(2, mButtonColumn0);
        }

Then you can add some actions inside cell click event. I found this is easiest way of doing it.

    private void dataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
    {

        int rowIndex = e.RowIndex;
        int columnIndex = e.ColumnIndex;

        if (dataGridView.Rows[rowIndex].Cells[columnIndex].Selected == true && dataGridView.Columns[columnIndex].Name == "ColumnA")
         {
               //.... do any thing here.
         }


    }

I found that Cell Click event is automatically subscribed often. So I did not need this code below. However, if your cell click event is not subscribed, then add this line of code for your dataGridView.

     this.dataGridView.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView_CellClick);
