Hiding ContextMenuStrip and Spawned UserControl When Running Dynamically

Posted on 2014-02-12
Last Modified: 2014-02-12
I need to programatically (dynamically) raise a specific contextmenustrip item called "Edit parameters" for controls on a Windows form (user GUI).   The loop below shows how the controls are looped over, and how the contextmenustrip items for each control are filtered for an "Edit" item, and then that item is dynamically fired.   The problem is that the user control is also visible -- which is the typical operation when a user wants to edit parameters -- that is, show the user control after right-clicking on the control's contextmenustrip item.  

Is there a way to (a) programatically load the user control (when the contextmenustrip item called "Edit parameters" is dynamically selected) , and then (b) select the "Apply" button, without making the user control visible?    All of this dynamic programming is performed to programatically raise all of the "Edit parameters" contectmenustrips, which spawns the user control, and then selects the apply button button.   There is actually no way to use default user control options in a separate method because every time the user changes the parameters, the controls and parameter values are serialized -- so yes, serializing is also being done.    However, the major issue is that I don't want the contextmenustrips to be visible during dynamic spawning and I don't want the user control to be visible when the "Edit parameters" item of the contextmenustrip is dynamically selected.  

How can this be done when keeping contextmenustrips invisible and user controls invisible?

The code below loops through each control's (in Me.Controls) contextmenustrip items to determine if an "Edit" item is found, and then raises the UC dynamically:

For Each ctitem In nxgContextMenuStrip.Items
             If InStr(ctitem.Text, "Edit") > 0 Then
                ctmseditparam_Click(ctitem, e)
                CurrentUCForm.Visible = False
                Dim btn As Button = CurrentUCForm.Controls("ApplyButton")
                serializeBtn_Click(CurrentUCForm, e)
             End If

Open in new window

The code below raises the UC when the contextmenustrip item called "Edit parameters" of each control in Me.Controls is dynamically selected in the loop above.   Problem is, the UC is not invisible to the user.

        Dim myform As New Form
        myuc.autosize = True
        myform.AutoSize = True
        myform.Dock = DockStyle.Fill
        myform.Width = 0
        myform.Height = 0
        myform.Width = myuc.width
        myform.Height = myuc.height + 50
        myform.Left = 0
        If runbuttonclicked = 1 Then myform.Visible = False 'this does not hide the UC
        myform.Top = 0
        Dim btn As New Button
        btn.Text = "Apply"
        btn.Top = 10 ' myform.Bottom - 50
        btn.Left = 10 ' myform.Left + 10 'myform.Right - 60
        btn.Name = "ApplyButton"

Not sure I fully understand your problem.

There are couple of options based on my understanding of your problem.

1) Move code to separate functions which can be called from UI code when user uses the contextstrip and user control and which can also be called from other code programmatically.

2) Make the user control configurable or use a flag of some sort so that user control is not shown to the user when triggered programmatically.

I was able to hide the user control (form) however, I can't seem to hide the contexmenustrips when looping through their items to find an item with "Edit"

Does a contexmenustrip need to be visible in order to be used dynamically? I basically need to replicate what a user does when setting run parameters for a task control (in me.controls) by dynamically using g the contextmenustrip.

Thus, how can the items of a contextmenustrip be looped through without seeing the contextmenustrip during dynamic usage?

Again, can you not move code out of ctmseditparam_Click handler into a separate function which you can then call without needing to loop through the contextmenustrip.
