UncheckAllNodes Method

[Nadia]

Hi,

How can I access this method for RadTreeView. It seems that I've got only "CheckAllNodes"?

Thanks, Nadia

Hello Nadia,

In the ticket info I see you are using a RadTreeView for ASP.NET AJAX. Is that true?

Actually there is method UncheckAllNodes() but it is available for the classical RadTreeView - not ASP.NET AJAX version. In this help topic you can see how to check/uncheck all child nodes.

All the best,

Yes, I'm using ASP.NET AJAX to uncheck from server-side, not from client side. Is there any methods to do that?

Thanks, Nadia

Hello Nadia,


One suggestion is calling the same method described in documentation from server code by passing the node Text as parameter. And in the client function, get the corresponding node by using findNodeByText() method and then follow the same logic to 'check/uncheck' child nodes.

Go through the blog to get help in "Executing JavaScript function from server-side code".


Hope this helps,
Shinu.

Hello Nadia,

After further testing I figured that there is method ClearCheckedNodes() for the Q1 SP2 . At this moment this will be helpful for you.

If you upgrade to the Q2 version you can use the UncheckAllNodes() as it is valid only for latest version.

Hope this helps.
