databinding

[vaporpop]

I have a checkbox (along with textboxes) that I am trying to use as a
databound control to an integer field on a database. I am using
Format and Parse with the checkbox to write -1 to the database if the
checkbox is unchecked and 0 if checked. I am finding that the Dataset
and Database are not updated if I change the checkstate of the
checkbox and when I change the checkstate of the textbox, the other
controls (textboxes) will not allow focus. The code I have written is
below. Any suggestions would be appreciated.

// chbActive
System.Windows.Forms.Binding chkBoxBinding = new
System.Windows.Forms.Binding("CheckState",
this.tblEmployeeBindingSource, "inActive", true);

chkBoxBinding.Format += new
System.Windows.Forms.ConvertEventHandler(IntegerToCheckState);

chkBoxBinding.Parse += new
System.Windows.Forms.ConvertEventHandler(CheckStateToInteger);

this.chbActive.DataBindings.Add(chkBoxBinding);

this.chbActive.CheckStateChanged += new
System.EventHandler(this.chbActive_CheckStateChanged);

//this handles integer to checkstate
private void IntegerToCheckState(object sender, ConvertEventArgs
cevent)
{
// the method converts only to CheckState inActive is 0 if false
if ((int)cevent.Value == 0)
{
chbActive.CheckState = CheckState.Checked;
}
else
{
chbActive.CheckState = CheckState.Unchecked;
}
}

private void CheckStateToInteger(object sender, ConvertEventArgs
cevent)
{
// if Active is checked then they are active and inActive should
be 0
if (chbActive.CheckState == CheckState.Checked)
{
cevent.Value = 0;
}
else
{
cevent.Value = -1;
}
}

Hi,

I did not completely evaluate your code, however, do you know that if you
change the checkstate, you are throwing the event that it is changed.

In my idea is that almost endless in your code. A solution?. Remove the
handling of the event direct after that you use it and set it again if you
have changed the values.
