I have a checkbox in a datagridview and it is passing a null value instead of a false/0 when user doesn't click on it. How can I change it, so it passes a value. I already tried passing values explicityly through the bounddatacolumn properties in the datagridview... |

Unfortunately none of the solutions suggested worked. Here is what worked for me:
The value passed is not even null. there fore I had to convert to a string and then compare its length..
private void DGView_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
{
int RowEdited = e.RowIndex;
if (DGView["MfgColumn",
RowEdited].Value.ToString().Length <= 0)
DGView["MfgColumn", RowEdited].Value = 0;
}

How are you getting the values?This works for me
| |
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim chkCol As New DataGridViewCheckBoxColumn
chkCol.Name = "CheckMe"
chkCol.HeaderText = "Check Me"
DataGridView1.Columns.Add(chkCol)
DataGridView1.AllowUserToAddRows = False
DataGridView1.RowCount = 5
For Each r As DataGridViewRow In DataGridView1.Rows
Dim val As Boolean
val = CBool(r.Cells(0).Value)
Trace.WriteLine(val)
Next
End Sub
End Class

Have you modified the DataGridViewCheckBoxCell.ThreeState property? |
