Adding button object to DataGridView

Question

I Need help adding a button to a cell of my DataGridView. It's not working with the code i'm using (see below).

I'm getting an error: No best type found for implicity-typed Array

DataGridViewButtonCell btn = new DataGridViewButtonCell();
this.dataGridView1[0,100] = btn;
this.dataGridView1[0,100].Value = "Button";

What i'm trying to accomplish is to add the 2nd column on this row with a button: (but it's not working)

dataGridView1.Rows.Add(new[] { "A:", (button goes here) , textbox1.Substring(648 , 2) })

The second line should have worked and made the 1st cell in the 100th row a buttonCell. If it exists. The 4th line makes no sense. — TaW

Try this :

int index = DataGridView1.Rows.Add("Test1", "Test2", "Test3");
DataGridView1.Rows[index].Cells[2] = New DataGridViewButtonCell(){ Value = DataGridView1.Rows[0].Cells[2].Value}

A btn is a string?

Oops! Let me try something. I'll test using object instead of string. I didn't see you were trying to insert 2 string and your button.

I updated my answer. I tried thoses 2 very lines in VB.Net with success.

Use the @name format in comments to reply to someone. You should use the returning index of the row: int index = DataGridView1.Rows.Add("Test1", "Test2", "Test3"); Then you can use that index: DataGridView.Rows[index].Cells...

Ok thanks @LarsTech I'll update the answer with your suggestion.
