Problems with AjaxRerender

[sesam]

Hi,

sometimes very strange things happen after AjaxRerender.
Please have a look at the part of your V2-Demo attached. Press the test button
and try to open the context menu again...

Best regards,
Andreas

Hi,
after clicking the test button (IWCGJQContextMenu.AjaxReRender)
all the controls in IWFrameRegion don't react / fire any more.
I could mail you my compiled JQueryDemoIW14_V2.exe...

Best Regards,
Andreas

UP !

Hi !

I have exactly the same problem with the last beta release 3.0.0.101.

Here the process :

- I have a frame with a grid alClient inside
- My contextmenu is set to the grid
- My context have a first item "Filter" with a subitem type checkbox "Activate".
- On the onchange of the checkbox item i change the property selected of the subitem.
- Now i need to call ajaxReRender on the event Hide of the contextmenu if i want to have the subitem checked when i reopen
- After the hide event, my grid doesn't respond anymore, the context menu doesn't show too. It's like there is an invisible region above the frame.

Hi Eric.P,

Please check your browser console, for js error (F12).

Best Regards.

There are no errors when i open / hide the contextmenu but i have an error when i display the frame

4 png attached.

At the ERR4, i can't do anything, right click show the contextmenu of googlechrome, i can't click on the grid or the nav buttons on the bottom of the grid.

Hi Eric.P,

Try to set ServerController.JavascriptOptions.Debug = True & UseUncompressedFiles = True

Then, check the errors again.

I guess, it's because of bad usage of AjaxReRender....

Best Regards.

Re,

I set the options debug and UseUncompressedFiles to trueand i got more info.

The console still doesn't have error or warning, the moment when i close the context menu is on the png attached.

For the use, i click on the hide event of the contextmenu and i wrote this :

procedure TwebGridFra.IWCGJQContextMenuGridJQContextMenuOptionsEventsHide(
Sender: TObject; AParams: TStringList);
begin
IWCGJQContextMenuGrid.AjaxReRender;
end;

Regards.
