Windows form VB.net tab control

Question

In a VB.net Windows form, it has a tab control with several tab pages. One of the tab page it has a groupbox with several radio buttons in it. The tag of the groupbox is binded to a dataset field. On the tab control "Selecting" event  to select that tab page, it refreshes the binding dataset and after to check the radio button using the tag value binded to the groupbox. It never works in terms of checking off the radio button the very first time when selecting that tab page and it will work in checking off the radio button after. Don't understand why and how this happens?

Answer 1

 

-> The tag of the groupbox is binded to a dataset field. On the tab control "Selecting" event  to select that tab page, it refreshes the binding dataset and after to check the radio button using the tag value binded to the groupbox.

 

How do you use the “selecting” event to refreshes the binding dataset?

Could you please give me an example?

Answer 3

Instead of checking the tag value to the groupbox to check off/on the radiobutton. I have to use the "GetData" method in the tableadapter to get the value of the column (assuming that always a single row is returned) and then write a "select case" statement to chcek off/on the radiobutton inside the groupbox.

So on the tab control "selecting" event if the tab page is selected and it will run a sub routine to check the value of teh column as follow:

Here is one of the example

    Dim str_teeth_restore As String
    Dim baseline_survey_id As Integer
    baseline_survey_id = Me.dgv_baseline_survey_list.CurrentRow.Cells("dgv_baseline_survey_list_txt_baseline_survey_id").Value
    str_teeth_restore = Me.ta_mucositis_sialometry_one.GetData(baseline_survey_id).Item(0).teeth_restore.ToString
    Select Case str_teeth_restore
      Case "Y"
        Me.sa_rb_teeth_restore_yes.Checked = True

      Case "N"
        Me.sa_rb_teeth_restore_no.Checked = True

      Case "U"
        Me.sa_rb_teeth_restore_unknown.Checked = True

      Case Else
        Me.sa_rb_teeth_restore_yes.Checked = False
        Me.sa_rb_teeth_restore_no.Checked = False
        Me.sa_rb_teeth_restore_unknown.Checked = False

    End Select
