refresh grid in parent form from popup form.

[Saro]

Hello,
I have a grid on Form A. I have data in the session variable which is set as the datasource in the grid's needdatasource

RadGridItems.DataSource = Session[cKIWebHelper.SelectListSessionVariables.const_Session_GridData];

Now, i display a popup form B

window.showModalDialog

then when I am finished doing what I have to do in the popup form I update data into the Session[cKIWebHelper.SelectListSessionVariables.const_Session_GridData]; (add records, remove records etc)

immediatlyl after I close the popup I would like to refresh the grid in Form A. How do I do FormA.RadGridItems.Databind() ?

If I understand your requirement correctly, then I believe you will find a solution for refreshing the FormA.RadGridItems after closing the modal popup in this forum thread:

Refreshing the parent page on close

I hope this helps!

Thank you very much for sending me this.  This is very helpful.  My code is behaving far better now.  I am wondering if I can somehow make it slightly better.
Now the grid refresh but so does the entire form.  IsPostBack value is set to false.  Therefore everything gets repainted. I played around with some session variables and was able to kind of go around the page load. 
But is there a better way of passing the Parent web page handle to the child for so that the child form issues a form.grid.rebind()?

Imagine you have grid in formA.  You pop a modal form B.  FormB then adds some records in to a session object. NOw you close formb and want to refresh just the grid in formA not everything else.Maybe this is not possible in web world.
Thanks for your help though

If you simply want to refresh the RadGrid that's located on your parent page, and not the entire page, you can use the solution that's demonstrated by the Grid/Window Editing online demo, and covered in the following forum thread:
