Click and DoubleClick

[moongodess]

Hi! I hope you can help me somehow, because I have a big, big problem...

 

I have a grid with some rows.

 

When I click a row my program must verify if there are some specific (important) details for the selected guest (row).

If there are, it must show the 'details window'.

When I double click a row it must do the same, but after closing the details window, must open the 'master window' of that guest.

 

When I make just one click, everything works fine, but when I make double click not so good :(

If there are no details the master window appears.

If there are details the 'details window' appears, but when I close it the other window doesn't appear.

 

Do you have any idea for what I need? Please..

What's the code you're using currently to do this?

The code is the following:

[size=1][font=Verdana]Private Sub gdxSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles gdxSearch.Click
     If (gdxSearch.HitTest = GridEX.GridArea.Cell) Then
        msSelectRow()
     End If
  End Sub
  Private Sub gdxSearch_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles gdxSearch.DoubleClick
     If (gdxSearch.HitTest = GridEX.GridArea.Cell) Then
        msSelectRow(True)
     End If
  End Sub

  Private Sub msSelectRow(Optional ByRef bolOpen As Boolean = False)
     On Error GoTo ShowError

     Dim gdrRow As GridEX.GridEXRow = gdxSearch.GetRow()
     Dim intId As Integer = CInt(gdrRow.Cells("GuestId").Value)
     Dim intType As Integer = CInt(gdrRow.Cells("GuestType").Value)

     Dim bolRefresh As Boolean = False

     ShowPopup(intId)

     If (bolOpen = True) Then
        Id = intId
        If (Id > 0) Then
           Select Case Mode
              Case Open.Sch
                 Dim f As frmUpdate
                 f = New frmUpdate

                 f.Id = Id
                 f.Type = intType
                 f.ShowDialog()
                 bolRefresh = f.Saved

                 f = Nothing
              Case Open.Sel
                 Me.Close()
           End Select
        End If
     End If

     If (bolRefresh = True) Then
        intStartAt = 0
        msRefreshGrid(Direc.Front)
     End If

     Exit Sub
ShowError:
     InfoError(Err.Number, Err.Description)
     Exit Sub
  End Sub

  Public Sub ShowPopup(ByVal intId As Integer)
     On Error GoTo ShowError

     Dim bolShow As Boolean = DbParameterGet(PIPopupShow, PVPopupShow, PTBol, PDPopupShow)
     Dim bolExists As Boolean = DbPopupExists(intId)
     Dim strShow As String = GetSetting(SetApp, SetSec(intId), SetKeyDate, DateString)
     Dim dtmShow As Date = CDate(strShow)
     Dim bolDate As Boolean = (dtmShow < DbHotelDate())

     If ((bolShow = True) And (bolExists = True) And (bolDate = True)) Then
        Dim f As frmPopup
        f = New frmPopup

        f.Id = intId
        f.ShowDialog()

        f = Nothing
     End If

     Exit Sub
ShowError:
     InfoError(Err.Number, Err.Description)
     Exit Sub
  End Sub[/font][/size]

Have you tried putting breakpoints in the Click and DoubleClick event handlers and seeing what exactly is being called when you double click?

[DiverDan]

Is the double click behaving the same as the click. I ask this because I once had the same problem and ended up using the SelectedIndexChanged sub instead of the Click sub to solve the problem.

Yes.. Let me try to explain what happens...

 

If I have no breakpoints:

- If I doubleclick and there are no details to show it shows the main windows as supposed to (and also a message just to indicate that it was a double click)

- But, if I double click and there are details to show it shows the detail window, but doesn't show the message box and the main window :(

 

If I have break points:

- It always work as if it was a single click

 

It seems to me that showing the detail window is 'disabling' the double click for some reason :(

My only problem using SelectedIndexChanged (or stg like that) is that I don't wanna show the detail window if the user is navigating in the grid with the keybord.

But... If I can find a way to know if it was a click or a keypress........ It would be great!! Does the 'sender' object gave me that?

Sorry, but I'm not to familiarized with the newm objects of vb.net :)
