I have an mdi project that has different toolstrips for different child forms. how I can have them merged into the MDIParent toolstrip as they show within the Parent. have all the toolstrips on the MDIParent and enable/disable depending on the childform?
View 8 RepliesI have a toolStrip with several buttons. Each button opens a new form.
With some forms I disable just its button, but with others I disable three buttons.
After I close any form, I re-enable the button.
As it isn't always the same amount of buttons, I'd like to do a routine to re-enable the buttons after I close any form. I've tried with:

I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.

in An MDI form , i make a childform with textboxes. these textboxes are produced by the code, like this:
For i As Integer = 0 To number Step 1
Dim TextBox As New TextBox

In another sub within the MDI class i want to read the data from the textboxes, but got an error that says txtBox1 is not a member of 'WindowsApplication1.Form1'.This is true because they do not exist yet. How can i handle this? I think it has something to do with "delegate and invoke", but this seems to be hard to understand.

I'm trying to accomplish something and not sure it can be done or rather if I'm approaching it correctly. Is there a way to access a MDI Parent's menustrip without merging the childform into it? I've done the merge before and that works fine. Reason I'm trying to figure this out is that I've started toying with a windows ribbon control and am wondering how the menu functions are performed with this control. In other words you wouldn't create one on each child form and have some how merge them so there must be a way to do this from the parent control.
Things I've tried thus far are to create a public sub in the childform that will save the data to a database. Once the save button is clicked in the mdi parent's menustrip and determines the activechild it will then call that sub procedure on the childform. However it doesn't persist the data, in other words passes a whole lot of nothing to the database even though the values don't dissappear on the child form.
Even i have use the "BringToFront" keyword for the childform but its not working. The buttons on the main form are still displayed above the childform. But when i open another form from the childform, it is displayed properly

View 7 RepliesI am in the process of upgrading a VB6 Project to Vb.net. My problem is that when I open a child form in my project from within the Parent form a new instance of the Parent form is created. The code is fairly simple:

The Parent has a Tool Strip and on the tool strip is a button that when clicked loads the child, this works fine.But when I set the child form to maximize its title-bar jumps over the Parent tool strip. Pushing it down a bit. I do what this. I would like the child to be completely contained within the Parent including the Parent forms tool strip.

View 1 RepliesI have an application built in vs 2008. The main form is a MDI form with a datagrid for record selection. When the user double clicks on the datagrid it opens a child form with the selected information. the problem I'm having is once the child form appears if I move the mouse up and down I can see the cursor moving as if I was holding the mouse button down on the datagrid and selecting/deselecting multiple records. It will do this until I click on the child form. I've tried setting the focus to the child form but to no avail. It's almost as if the MDI form doesn't realize the mouse button has been released until I click on the child form.
