User control or sub-form inside tab-pages? Best practice?

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :Windows Application
I've got a Windows Forms application with numerous tab-pages within a tab-control. Each tab-page is a diffirent user entry form with different controls of varying types. As the application is fairly large it is important that more than one developer can work on it simultaneously. Thus we decided to create a form for each tab so that different developers could work on different forms at the same time without overwriting each other's code. Each of these "sub-forms" are then assigned its relevant container tab-page as its parent. This works well but I was wondering if this is good practice or not, after another colleague commented that we are making forms look like user controls and that we should rather be creating a user control for each tab. I've converted two of the forms to user controls with relative ease and it does work nicely as well but with one draw back. On the main parent form, e.g. frmMain, where the tab control lives, there is one single button the clear the current display. When you click "Clear display" it clears various others items displayed on the main from, finds the current selected tab and clears its contents. The latter is easy to do with sub forms as I can simply close and dispose the sub form inside the selected tab, and load a new instance. I don't have to write custom logic to go and reset/clear each control on that form. Thi

DataGrid in a User Control. How to make it resizable in a form.


I embed the DataGridView control in a User Control.  The datagridview covers the entire user control.

When I used the user control in a form, I want to be able to size it the way I want to.  When I expand and shrink the user control, I want the embedded DataGridView to grow and shrink accordingly with the user control.  How would I go about doing that?

Without changing any of the default property values, when I place the user control on a form, the size stays fixed when used in a form.  That seems to happen only when you have a DataGridView in a user control.  

Thanks in advance.

User controls are not being removed from the main form control




I have the following piece of code:


foreach (Control ct in this.Controls) { if (ct is uctAssignment) { ct.Hide(); ((uctAssignment)ct).CloseMe(); }

  public void CloseMe()
If I have 15 controls to be deleted, it only deletes about 4 or 5 at a time, such that I have to envlose the above foreach loop inside a for loop.

In addition, when I make a call to Control.Hide() inside a similar loop, I can observe the same behavior.

Does anyone know why is it behaving like that?

Any ideas?
