Telerik RadWindow keep it open

[Ravi]

Hi,
Here is my scenario:
Parent page:
I have a text box and a button for search feature.  Once I click the button I am opening a radwindow by javascript. Works fine and I display the results in a grid.  Now when I click on one result it should refresh the parent page with the selected value.  Works fine.

The problem:
When I click on the result and Parent page refreshes but it closes the RadWindow that's been opened.  I do want to keep this radwindow till I decide close it.  This way I can refer back to the results and view each result in the parent page.  How would I keep the rad window open all the time (Not loosing it when the parent page refreshes).  Please advise.

Thanks,

Hi Ravi,

The RadWindow is entirely a client-side object, its UI is created via JavaScript when it needs to be shown. This allows us to greatly reduce the markup that needs to be sent from the server, especially in cases where many RadWindows are needed.

This also means that since the control has no server rendering there is no way to persist it across postbacks that dispose the entire page on the client.

What you can do is use AJAX - the postback from the Grid can update the grid and the other panel that shows information (both placed in UpdatePanels), thus disposing only these parts of the page and leaving the RadWindow out of the response.


All the best,

Marin,
Thank you for your response.  I did really thought of that using Ajax to update panels but in my case I will be clicking on several links on the parent page yet I would want to keep the radwindow open still.  Would you have any other suggestion for this kind of scenario?

Hi Ravi,

To preserve the state of RadWindow opened on client using JavaScript, I would suggest you to use a hidden field to store the window's current state. And then on the server set the RadWindow's VisibleOnPageLoad property according to the value of this hidden field. For your convenience I have attached a sample page demonstrating this approach.

Also, if you are using RadWindowManager on the page do display RadWindows, you can set PreserveClientState property to true.

I hope this helps.

Thanks Marin,

This is what I need, to keep the pop up window (which contains its own grid) open on a click, so they can sort columns, etc.  Do you have an example of how we would structure this?

Thanks,

Tim

Hi Tim,

I believe this article will help: http://www.telerik.com/help/aspnet-ajax/window-ajaxifying.html.

You may also find useful this one on opening it from the server: http://www.telerik.com/help/aspnet-ajax/window-troubleshooting-opening-from-server.html.

Hi,

I tried setting the PreserveClientState="true". This only keeps the radwindow open even when the main page refreshes but does not retain the web page it is directed to. It just behaved it was an empty radwindow. Is using an update panel mandatory to keep the radwindow open and refreshing when the main refreshes?

Hi Kiran,

The PreserveClientState property sets a value indicating whether the RadWindow objects' state (size, location, behavior) will be persisted in a client cookie to restore state over page postbacks/visits. It does not take care of the page refresh in the content area iframe of RadWindow.
