How to call Datagridview cell double click event from a button?

Question

I'm trying to call datagridview cell event method from an another button.

DataGridView Cell Double Click Method

private void ListDataGridView_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex >= 0)
            {
                ListDataGridView.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
                DataGridViewRow row = this.ListDataGridView.Rows[e.RowIndex];

                comboBox2.Text = row.Cells[1].Value.ToString();

            }
        }

This is Button where I'm calling this method

private void button6_Click(object sender, EventArgs e)
{
  ListDataGridView_CellDoubleClick(sender, e);
}

Error I'm receiving

Error 3 The type or namespace name 'DataGridViewCellEventHandler' does not exist in the namespace 'System' (are you missing an assembly reference?) C:\VisualC#\Projects\DataGridViewApplication\DataGridViewApplication\List.Designer.cs 340 46 DataGridViewApplication

What I did:

I changed EventArgs to DataGridViewCellEventArgs.

private void button6_Click(object sender, DataGridViewCellEventArgs e)
   {    
     ListDataGridView_CellDoubleClick(sender, e);
   }

Now I'm receiving Error:

this.button6.Click += new System.EventHandler(this.button6_Click);

Error 3 No overload for 'button6_Click' matches delegate 'System.EventHandler'

C:\VisualC#\Projects\DataGridViewApplication\DataGridViewApplication\List.Designer.cs 340 35 DataGridViewApplication

Now I changed button event handler code to this

this.button6.Click += new System.DataGridViewCellEventHandler(this.button6_Click);

Still Receiving this error and stucked here

Error 3 No overload for 'button6_Click' matches delegate 'System.EventHandler'

Found a solution here: How to call a datagridview event with a click of a button?

private void button6_Click(object sender, EventArgs e)
        {
            ListDataGridView_CellDoubleClick(null, null);  
        }

but this is not working for me, it gives me an error.

Object Reference not set to an instance of an object.

As another option instead of trying to call event handler of `CellDoubleClick`, you can put the logic in method like `DoSomething` and call it in both `CellDoubleClick` event and `Click` event of your button. For example, take a look at [this post](http://stackoverflow.com/a/38611739/3110834). — Reza Aghaei, Aug 18 '16 at 12:11

    private void button6_Click(object sender, EventArgs e)
    {

        ListDataGridView_CellDoubleClick(this.ListDataGridView, new DataGridViewCellEventArgs(this.ListDataGridView.CurrentCell.ColumnIndex,this.ListDataGridView.CurrentRow.Index));

    }

I would expect you have this at the top of you Form.cs file:

using  System.Windows.Forms;

Eventhandlers are strongly typed, so both event and handler need to have matching types.

The Click eventhandler requires a method signature of void(object sender, EventArgs e) so your initial code was the right approach:

private void button6_Click(object sender, EventArgs e)
{
  // create and set values for the event argument. 
  // it can't be EventArgs, so just instantiate the right type
  // the constructor needs a row and column
  var datagridviewArgs = new DataGridViewCellEventArgs(42,13);
  ListDataGridView_CellDoubleClick(sender, datagridviewArgs);
}

but as you can see you need to provide the correct type for the second parameter, the DataGridViewCellEventArgs, on the call to ListDataGridView_CellDoubleClick.

Use this...

private void btnChoose_Click(object sender, EventArgs e)
{

    MouseEventArgs b = new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 2, 
        MousePosition.X, MousePosition.Y, 0);
    DataGridViewCellMouseEventArgs a = new DataGridViewCellMouseEventArgs(0, 0, 
        MousePosition.X, MousePosition.Y, b);
    dataGridView1_CellMouseDoubleClick(sender, a);
}
