VB.net Binding Controls to BindingSource with Formatting

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:
dtpickerDate.DataBindings.Add("Value", bsReading, "Reading_Date", True, DataSourceUpdateMode.OnValidation, DateTime.Today)

Open in new window


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

I have found out that you can setting the format when you bind the text box using
txtUsage_InServ_Cost.DataBindings.Add("Text", bsUsage, "RunningTotal_Cost", True, DataSourceUpdateMode.Never, vbNullString, "c5")

Hi,

Another formatting issue with a bound textbox, I would like to format the following as two decimal palces (rounded up).

How can I achieve this?

 txtUsage_TTM_CostDaily.DataBindings.Add("Text", bsUsage, "TTM_AvgDailyCost")

Again, you can use Validating or TextChange event of Textbox.

Hi,

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

Open in new window


but I get an error, "Input string was not in a correct format."

What does the textbox contain when you this code runs?

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
