NodeTemplates and ExpandMode "Webservice"

[JP]

Hi,

regarding this topic I just found 3 year old threads, so maybe this feature was implemented in the meantime:

I need to have nodes which have more than one icon: I need icons which do a postback the same way as the context menu items can do this. As far as I know I can achieve this by using NodeTemplates.

But I use ExpandMode="Webservice", and three years ago this wasn't possible.
Is it possible to achieve the things I want with the current version?

Regards,
JP

Hello,

This is one post about having more than one image per node and that you can use node templates for this:

I found these two threads when searching for "nodetemplate webservice" because I want to populate the tree by using a webservice:

Hi Jp,

Unfortunately as it is mentioned in one of the forums that you listed,  node templates will not work with nodes added by Web Service.

The only work around that I could think of is to use the following code to add an image and use the NavigateUrl property to redirect to the page:

foreach (DataRow row in productCategories.Rows)
        {
            RadTreeNodeData itemData = new RadTreeNodeData();
            itemData.Text = "<img src='rainy.gif' />";
      itemData.ImageUrl = "rainy.gif";
       itemData.NavigateUrl = "http://www.telerik.com";
            itemData.Value = row["CategoryId"].ToString();

Hope this will be helpful.

All the best,
