VB.net Binding Controls to BindingSource with Formatting
Posted on 2014-02-06
Hi,
I am creating a database application and have bound my form controls to the binding source.
One of the form controls is a DateTimePicker and the DataBinding is:
How can I format the DataBinding so that when the value is sent back to the database it does not include the current timestamp or the current timestamp is set to 00:00:00.
I am using a DataAdapter to to insert/update the data.
Thanks, Greg

One option is to use either Validating or ValueChanged event of date time picker to remove the time part.

Hi,
I have tried the following code:
but I get an error, "Input string was not in a correct format."
I have tried the following code:
Private Sub txtUsage_InServ_CostDaily_TextChanged(sender As Object, e As System.EventArgs) Handles txtUsage_InServ_CostDaily.TextChanged
txtUsage_InServ_CostDaily.Text = Convert.ToInt32(txtUsage_InServ_CostDaily.Text)
End Sub
but I get an error, "Input string was not in a correct format."
What does the textbox contain when you this code runs?
Try
Try
Private Sub txtUsage_InServ_CostDaily_TextChanged(sender As Object, e As System.EventArgs) Handles txtUsage_InServ_CostDaily.TextChanged
If Not String.IsNullOrEmpty(txtUsage_InServ_CostDaily.Text) Then
txtUsage_InServ_CostDaily.Text = Convert.ToInt32(txtUsage_InServ_CostDaily.Text)
End If
End Sub
