I don't understand the comment you left on my answer. this.Controls.SetChildIndex works perfectly for me. Maybe I didn't understand your question. I don't know why you would have controls on your form that would be in the same location as a DataGridView anyway. Is your problem that you have multiple controls on a form that are over that form? Or is it that you have two forms and you want to bring one of the forms to the front of your screen? If my answer didn't help, then I must not be understanding your question.

Next time, only provide the code that is directly related to your question. The majority of that code has nothing to do with your question.

Now, to answer your question, use

C#

this.Controls.SetChildIndex(gv,0);

after you add it to the controls collection. This will tell the UserControl to draw it first before anything else.

Also, as an FYI, it is not good practice to call

C#

DataGridView gv = new DataGridView();

outside of a method. That should really be placed inside the contstructor.

You can declare gv globally still, but you shouldn't call new outside of a method.

Solution 3

Hi

to clarify:

To get control to front just add the line

gv.BringToFront();

after making new instance;

DataGridView gv = new DataGridView();

This should look like this:

C#

DataGridView gv = new DataGridView();
gv.BringToFront();

this should help.

Solution 1

Try setting the zindex of the dynamic control.
Search on msdn to read / learn more about this property.

Reason for my vote of 1
what kind of control directly exposes the ZIndex?
