I have a form with a subform that is a continuous form. I have a tab control that displays information related to the record selected in the continuous form; the tab control displays as soon as a record is selected/clicked. That all is grand.
However, after the user updates information in the tab control and clicks a button, I want to hide the tab control until a record is actually clicked on the continuous form.
What is currently happening is that the first record in the continuous subform is selected and I'd like for no record to be selected.
Is there a way to set the current record/selection of a continuous form to nothing or null? I've tried setting the bookmark on the continuous form to null in the button click event using Parent.SubApptList.Form.Bookmark = Null and that does not work for me.
Seems like it should be easy, but I can't figure it out.
After the button click event could you set focus to the parent form? Doing this would force the user to click on a record. Maybe I'm not fully understanding exactly what you're trying to do but if all you want is for nothing to have focus after a button event then that's the route I would take. That's assuming you don't having any on focus events for thr main form.

I am working with a Visual Basic.NET project in Visual Studio 2017 (.NET Framework 4.6.1)
I am using a Listbox which is associated with a BindingSource.
The Listbox is contained within one pane of a SplitterControl.
I also have a TabControl is located within the other pane of the SplitterControl. This control contains child data associated with the items in the ListBox and is refreshed when the ListBox is clicked and an item is subsequently selected in the ListBox. The Click event refreshes a Treeview, which then populates the TabControl with data if/when (1) a tree node is clicked and (2) appropriate data is retrieved for that node.
The Listbox Click event works fine while clicking different items consecutively within the Listbox only.
However, once the mouse clicks in the TabControl (in the other pane of the SplitterControl), then once the initial Listbox is clicked, the Click event doesn’t fire.
I have researched this issue (on StackOverFlow as well as other forums) and suggestions have basically revolved around the idea that the Click event could be forced by calling the routine set up as the Click event handler (e.g., myListBox_Click).
I have tried this, but the problem is that I am losing the current SelectedIndex / SelectedValue.
To illustrate by reproducing the issue within the app where I am encountering the problem:
The app in question (note the Listbox highlighted by the red arrow - Screenshot 1):
Screenshot 1
Upon startup of the app, the Listbox behaves as it should, if the user clicks nowhere else, only selecting various items within the Listbox. The TabControl (initial tab shown is always the Profile tab) is refreshed accordingly.
However, if at any point, the mouse is clicked in the TabControl (e.g., to select another tab, note Screenshot 2)
Screenshot 2
Now, when the user clicks on another item in the Listbox, the wrong item is selected (shown in Screenshot 3):
Screenshot 3
The Click event is now being forced via a call to MyListBox_Click within the TabControl_Leave event; my thinking was that this was the appropriate place to put the subroutine call. My reasoning was that when the Listbox was clicked in this scenario, the first event to fire (as far as I could tell) was the TabControl_Leave event.
Not surprisingly, if the same item in the Listbox (in this example scenario, Allegheny) is subsequently clicked, than the result is what should have happened on the previous click (that the SelectedValue is correct, as seen in Screenshot 4):
Screenshot 4
Of course, this is correct, since the last click occurred while the Listbox was already the active control.
I have tried several approaches such as (1) using a global variable to store the current index/value and retrieving it, and (2) using the Tag property of the TabControl to store and retrieve the same value. This has either worked inconsistently or not at all because of the order in which the control events fire.
Hopefully, I've been clear enough on the nature of my problem/issue.
Anyone have any ideas on what my next approach could be? Any ideas/insights/suggestions will, of course, be greatly appreciated.

I have a problem stated below....
I have a MDI form having different child form. if i open the form then if related data not exist in database, a suggestion banner should appear top of the forms to enter related data first. Even, if I close the child form, suggestion banner should remain open and Onclick on that banner go to specific form to add the record. There should be different banner of different forms. so please help me to implement this scenario.
Thanks in Advance.
I want to use which control as banner. so after struggling i fount panel best as banner. Setting panel property -> AccessibleRole = Alert. So I implement scenario easily.
Instead of opening the child form, open the banner form first (which opens the child form).
Then check in the banner form if the data has been entered. If it has:- close the banner form.
I'm using the VerticalGrid in MultiRecordView. Its Validate event fires when the grid detects that a record that has been changed is losing focus. I'm writing data to the database from this event.
My users want to use the keyboard left/right arrow keys to move forwards and backwards through the recordset, so I trap those keys and set the FocusedRecord accordingly.
If one of the row editors is a RepositoryItemRadioButton, the Validate event doesn't always fire. The users will click on the radio-button value desired and then, before they click on another row in the record, they'll hit the arrow key to move to the next record. The change to the radio button group has not been detected by the grid in that sequence of events.
The radio button change is detected only when the button loses focus.
Is there a way to cause the vertical grid to recognize that a radio button editor has been changed and fire the Validate event, if the user doesn't give another row in the record the focus?
I thought EditValueChangedFiringMode property controlled that behavior, but setting it to Default or to Buffered does not have the desired effect.
Thanks
I am building a database on MS 2003. I have one form which calls for a series of options. This form is based on the table "Categories" which is linked to the main table by Customer ID.
Now, both forms appear together on the same screen, what I am trying to do is have the person select one or more of the categories and in pressing a command button then those categories which were selected will show its respective forms. The forms are invisible until selected and until the command button is pressed.
Since they are two different forms (categories in one) and the entry form on another, How do I program the command button to make the entry form visible FROM the other form?
The sub-form is located in a tab. I dont want to show it as a pop-up but to become visible within the tab where it's located
If the form is open but invisible then you can refer to it as a member of the forms collection and make it visible:
forms("myForm").Visible = true
If the form isn't open then get its name from the AllForms collection of the project and then use the OpenForm method:
docmd.OpenForm currentproject.AllForms("myForm").Name, acNormal
Pseudologic: you are basically going to want to set the Visible property with all of your forms to False during the form's Open event. You should place this Visible = False code in a separate subroutine so that the code structure can be called during other events too. (For example you may want to provide a Reset button so that the user can reset the form, or trigger the "set false" code when a new customer id is selected.) Then with every selected category you would set its associated form property visible by setting Visible = True.
I am trying to hide specific columns in an Access 2007 split form through code. I need the form to check certain conditions to see whether it needs to display a column or not. I have code in the form's 'Activate' event to hide the column like this:
txtControl.ColumnHidden = True
This code works in the "Open" event, but if I hide the column on Activate, it won't display these changes until I close the form and open it again. I have tried calling the form's refresh, repaint, and requery methods, but this doesn't work. Please help!
Edit: Ideally, I need this event to occur whenever the focus switches to this form.That's why I'm using the Activate event rather than the Open event.
Try setting it in either the form's Current or Load events. You will also probably need to requery the control after setting that property: Me.TextControl.Requery Current is called every time a form's record is changed, the form is repainted or requeried. Load, as its name suggests, is called once, after the form has opened when the form loads its records. These have always been more reliable for me than using Activate, which really has to do with more the focus of the form, not really what you want.
I've had a problem like this before working in Access 2002. I was able to solve the problem with a subform by setting the subform source object equal to itself and then running the requery.
Me.SubForm.SourceObject = Me.SubForm.SourceObject
Me.SubForm.Requery
See if this technique works for your particular situation.
