Change value in DataGridView directly

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?

Solution 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.

Solution 2

If you are setting the datasource to an object, then the property linked to a certain field has to have a setter in order to change the value. Otherwise it is a read only property and will be treated as such. Not sure if that helps, its a bit unclear what you are after, and what you are working with.

@UniLe stackoverflow.com/questions/1814423/… is'n this helping? :)

yes, your are correct. It has just read property. How can I change my datasource that I can read and write there?

if you are using a custom object as your data source, the property in question needs to have a setter method public <Type> PropertyName { get; set; } Without the setter the data binding has no way to update the value in the bound object
