    I have a user control that contains 2 image buttons, when you click one of
    them, both must change the image source, the thing is that the first time
    you click any one of them the page appears to do a postbak, but the image
    source or the image displayed does not change until I click one of the
    images a second time, why dows it take 2 clicks for the user to "refresh"?

    TIA!

  2. TCordian,

    If the buttons happen to be in a user control that is being added to the
    page dynamically then give the control an ID by adding me.ID =
    "MyControlIDHere" to the page load of the control.

    I can't tell you why this works exactly, but it does. If this isn't a
    dynamically added control please show some source code and I'll see if I can
    figure out what's wrong.

    This usercontrol has 1 image button that is supposed to do the work, this
    control is used for country selection between 2 countries. It also has an
    <IMG> that shows the selected country (The imagebutton shows the other
    country option) so when toy click the image button it is supposed to change
    the <IMG> to show the newly selected country and at that time change a
    cookie value and a session var value to hold the current country ID, this
    should also refresh the page that contains the usercontrol to show content
    according to the current selected country.

    The imagebutton_click event is coded as follows:

    Private Sub imgNewCountry_Click(ByVal sender As System.Object, ByVal e As
    System.Web.UI.ImageClickEventArgs) Handles imgNewCountry.Click

    If p_IdPais = 1 Then

    p_IdPais = 2

    Session("IdPais") = 2

    Else

    p_IdPais = 1

    Session("IdPais") = 1

    End If

    'Set Cookie

    Dim ACookie As New HttpCookie("MyPageCountry")

    ACookie.Values("Pais") = p_IdPais

    ACookie.Expires = DateTime.MaxValue

    Response.Cookies.Set(ACookie)

    End Sub

    Then two more questions...

    1) How are you setting the image urls?
    2) What are the image names?

    I got the image thing to work, now there is another problem, When the image
    was clicked the usercontrol sets a session variable and a cookie, but there
    are other usercontrols in the same page that read that session variable when
    they load and depending on its value they load different information, the
    problem is that it appears as if they load before the click event from the
    image happens, the load when the imagebutton on the first usercontrol send
    the postback.

  8. TCORDON,

    Fixing this may require some re-tooling of your application.

    If you have multiple controls all counting on the same values then I think
    the safest way to do this is to set all of them only after the page load
    finishes.

    What you should do is create public subroutines in each control that can be
    called from the page they are contained in. Put the code for each controls
    changes into those subroutines. You can then reference each control just
    like you would any other .NET control by declaring it in the codebehind of
    the page the control is on.

    The next step is to use the OnBubbleEvent to check for the button click from
    the image button.

    Then call each of the other control's setup subroutines from within the
    OnBubbleEvent's code.

    Should that be on the OnBubbleEvent in the form or in the control that
    changes the value all other controls reference?

    Thanks

  10. It should be in the form.

    Each control "bubbles" it's events up to the default form. Since you need to
    make certain that all controls are loaded before you change them based on
    your session variable you can do this from the main form they are contained
    in since that form won't receive the bubbled event until all the controls
    have been loaded.

    To access the OnBubbleEvent you would use code like this:

    Protected Overrides Function OnBubbleEvent(ByVal source As Object, ByVal
    args As System.EventArgs) As Boolean
    Try
    Dim Control As System.Web.UI.Control

    '---If you have more than one button that could trigger control
    changes use a select case (otherwise an if/then would suffice
    Select Case Control.ID
    Case "[YourButtonIdHere]"
    '---Here you can call the public subroutines you set up on
    your controls
    Call MyUserControl.Setup() '---You could either set your
    session variables just before calling the subroutine or pass the necessary
    information directly in.
    Case "[AnyOtherButtonIDHere]"
    '---Fire any code here
    End Select
    Catch ExceptionCaught As Exception
    '---Hanle any exception here
    End Try
    End Function
