Hello page,

Thank you for posting in the community.

Your WebDataMenu is most likely being reloaded due to the query string changes themselves (it is interpreting it as an entirely new URL). Using an Application variable however, you can persist the selection by handling the ItemSelected and DataBound events. For instance:

Please let me know if this helps.

Hello Petar,

the event, that i catch is 'Item_Click'. If it fires, i use the

Item.Value

to load my content. This value was saved in the 'Application["Sel_Item"].

I also used the DataBound-Event, but it only fires once (if the page is opened for the first time and no Menu-Item was clicked.

So I used your foreach-loop inside the Item-Click Event, but my hierarchical menu was not expanded.

Any idea?

Hello page,

Thank you for your reply.

I am still researching the matter, however it seems that handling item click in this scenario may not be possible due to the navigation occurring when clicking on an item. As for having the menu expanded after postback I am unsure that this behavior is supported by the WebDataMenu (a WebDataTree or WebExplorerBar may be more suited for this task). I will continue my research on this topics and provide you with any information available.

Hello Petar,

i use the WebDataMenu on the bottom part of a page and the different Menu-Items open from left to right (each time only one part). So i don't think this is possible with the WebExploreBar. May be with the Tree. But the strange behavior is: if i started with the control, i used a item-click to expand the menu and i can catch the click event on client side and the menu stay expanded. (i only used the code behind because a an ado.net dataReader was easier for me to handle; use the value of the clicked menu item, to load the data).  Now if i use the default 'expand'-event (mouse hover) the menu close immeditely, if the mouse went out (that's correct but i see no way to let it expanded via code behind).

hope you find some answer soon, because it is for a running project.

Thanks

Patric

Hello Patric,

Thank you for your reply and feedback.

I am still working on this matter and will keep you posted of my progress.

Hello Patric,

Apologies for the delayed response.

I am attaching a sample illustrating how the menu may be opened after a postback to the currently selected item (with the querystring changing). Note, however that submenus would be closed after unhovering the menu (this is due to the control's design).

Please feel free to contact me if I may be of assistance.

Hi Patric,
