Updating datagrids from other windows

[bloukewer]

I have a datagrid on my main-window (which is always active until the appliction terminates). Is it possible to update & refresh those datagrids from other forms (which are activated from buttons clicked on the main-window). Here is some pseudo-code to explain how I activated the other forms:

Eventhandler btnAddClicked( .........)
dim frmAdd as new frmAdd
frmadd.showDialog()
end Sub

I tried setting the main-window as a mdi-container, but alas, unexplained erroneous behaviour strikes again! I'm sure some little green men have been doing experiments on my comp, thus the weird behaviour.

Anyways, as always, thanks for any replies.

PS. I'm actually not wondering how to update and refresh a datagrid, the problem is doing it from the "child" forms.

in the child form you could try something like this.

Dim formMain as new formMain
formMain.Datagrid.dosomething

or if you are using a button/sub/function to do the update im sure you could call it in the same way i.e.

Dim formMain as new formMain
formMain.UpdateGrid()

Here's a good article that explains how to communicate between forms: Multiple Forms in VB.NET. Part 4 - Accessing Controls and Data ...
