Question

How can I change the value from all cells in DataGridView Windows Forms? I want to change directly in Windows Forms, like typing directly in the cell

I have a table like:

AA    BB    CC
--------------
1     aa    ac
2     bb    fd// I type here and change the value to kk

Code:

DataGridViewTextBoxColumn AA= new DataGridViewTextBoxColumn();
MsgIDHex.HeaderText = "AA";
MsgIDHex.DataPropertyName = "AA";
DataGridViewTextBoxColumn BB= new DataGridViewTextBoxColumn();
MsgIDHex.HeaderText = "BB";
MsgIDHex.DataPropertyName = "BB";
DataGridViewTextBoxColumn CC= new DataGridViewTextBoxColumn();
MsgIDHex.HeaderText = "CC";
MsgIDHex.DataPropertyName = "CC;
dataGridView1.DataSource = result;
dataGridView1.Columns.AddRange(AA, BB, CC};

Should I do something with DataGridViewTextBoxEditingControl?

Answer 1

You can simply do this (assuming that you want to change one value programmatically):

dataGridView1.Rows[RowNumber].Cells[CC.Index].Value = newValue;

And how to enable editing of certain cell was already explained here.
