DataGridView Checkbox

[k09]

Hi,

I have a Checkbox column in the DataGridView.

I am unable to change the state of the checkbox.

Why is this??? What do I need to set in Properties?

Using Visual Studio 2005

Thanks.

You are probably databinding unconditonally on every Page_Load. If so, guard the databinding with an If (!IsPostBack) { ... }

I am building a Windows Application - not a webpage.

Can I still use Postback??

How should I set the databinding?

Thanks.

OK I am able to Check/Uncheck an unbound DGV CheckBox. Set Read-Only to false.

I want to bind the primary key of my table to the checkbox.
If I do this then I am unable to check/uncheck the checkbox.

Any ideas?

Thanks

This code works for me provided the user only checks the checkbox once...

How Do I ensure the ArrayList only adds when the checkbox is at checked state??

Thanks!!

private void counterPartyDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            DataGridView dgv2 = sender as DataGridView;

            if ((e.RowIndex != -1) && (e.ColumnIndex != -1))
            {
                ArrayList mySelectionArray = new ArrayList();

                if (e.ColumnIndex == 0)
                {
                    DataRow dr2 = ((DataRowView)dgv2.Rows[e.RowIndex].DataBoundItem).Row;

                    int mySelection2 = (int)dr2[dgv2.Columns[1].DataPropertyName]; // 1 = unique id column
                    mySelectionArray.Add(mySelection2);
                }
            }
        }

Checkboxes indicate true or false (boolean). Do you have a primary key using boolean data type?

Windows forms are statefull and, hence, they do not have a post back. Once the forms loads you have all the objects available until you dispose of them.
