Launch Modal window from radGrid

[rik butcher]

Guys, this is a really really weird one for me.
we launch a modal window from a rowClick in radGrid:

 

 

string strfunction = String.Format("OpenWorkOrderDetails({0},{1},{2},{3})",

 

wonumber, wotypeid, locationid, woid);

the code above basically does the "window.open(wonumber, wotypeid, locationid, woid); from javascript and runs the Page Load event of the Page it's Opening.
usually passing the variable 'woid'
HOWEVER. For the Life of the Session, it never ever runs thru that Page load event again - only the first time.
And, you can select other rows go to another tab in the program & when you come back when you click that same row, the screen comes up exactly as it did the first time - completely skipping the "Page Load" event. if any changes were made on that window, it doesn't show them. it only shows the original data.
we're not caching anything, so, i dont understand how this is possible.
here's the  top part of that page - run inside of a master page.
is there anything that you can see & have you ever heard of anything like this before?
thanks again for any help.

Hi Rik,

Have you tried setting the DestroyOnClose and DestroyOnClose properties of the RadWindow to true in order to force it to reload its content on each show? What is the result of using them?
Properties that Affect Window Behavior

[rik butcher]

none of those had any effect at all, either in radWindowManager or radWindow 

 

 

DestroyOnClose="true" ReloadOnShow="true"

 

 together or separate.
but, you are correct. the radGrid is definately caching for the life of the session.

[rik butcher]

do you need to see the code of the window being opened? i'm not really sure how the radGrid is doing a cache. does it by default use the RadWindowManager? do u need the javascript doing the window.open()? it's passing a few properties.
thanks for any help.
this one's very strange to me.

Hi Rik,

It seems that I have misunderstood you. You are actually not opening a RadWindow but a regular one using the window.open() method. I would suggest you to test your script with a simple asp:GridView instead of RadGrid to confirm whether the problem persists. This way you will know where to look at - the grid or your window opening logic.

All the best,

thanks, i had already done that and it works just fine with GridView. so, i'm asking how is the radGrid doing a 'cache' and how do i stop it?
thx
rik

[Tsvetina]

Hello Rik,

By default RadGrid has no caching, so there may be something else to this scenario. Could you please share your grid declaration as well, so that we can get a full idea of where the window is opened from?

[rik butcher]

thanks. here's the declaration  - we're using multipage view so there's several grids. just sending one of the ones involved:
i put the databind method below this - the OpenReleaseDetails calls the javascript. pls let me know if i need to include anything else and thank u so much for your help on this.

Hi Rik,

I tried a simple scenario using the main parts from your approach but could not replicate the issue, the Page_Load of the aspx loaded in the window runs each time. Take a look at the project and let me know what am I missing out.

Best wishes,

i found the issue. it was in the javascript itself. it starts out calling window.open but i dug deeper and it uses a method : window.showModalDialog which caches to the browser and stays.
just appending  the url called with:
 URL += "&rt=" + GetCurrentDateTime();
keeps this from happening.
that was the issue all along & not a telerik problem. thank you so much for being patient w/ me.
thanks again
