Hello again!

I have a problem setting style to the tree view items that are loaded on-demand. This is mainly because TreeViewItem's HtmlAttributes is read-only and therefore I can't set it. I did not find any way to set it on the View either:

1..DataBinding(dataBinding => dataBinding.Ajax()
2.    .Enabled(true)
3.    .Select("GetModuleVersions", Constants.ctrl_Module))

Hello Tatu,

Indeed, the HtmlAttributes are not available -- we will try to provide a mechanism to allow styling of the nodes that are dynamically loaded, and will post a follow up with a solution in this thread by the end of the week.

Thanks for the reply! I have a temporary solution using jQuery plugin called 'livequery' and using jQuery css methods, so this isn't high-priority feature (for me atleast).

Hello Tatu,

After inspection of the TreeView code, it turned out that providing such a feature will have effect upon all navigational controls (due to inheritance from the NavigationItem<T>). We will consider a better way of introducing this feature, but at the time being, using a work-around would be smarter.

That said, you can hold on to livequery (if it works in your scenario) or bind a handler to the DataBound event that applies the necessary styles to the items.

Binding handler to the DataBound event sounds good. I think I'll change to that one. Thanks for the reply.

Can you please post example code of how you would do this using the onDataBound event?  I believe others have this question as in the thread titled "How do you format TreeView ajax data?".

Thank you so much!

Hi Donna,

The attached solution demonstrates a work-around, in this case - using the Text field to transfer additional data.

Hi,

I'm struggling with this work around as the Text field is reformatted so the Bound function never finds the required spans and the text property simply renders them as text. I'm assuming I'm missing a setting or something? using Razor, which I'm assuming doesn't make any difference?

Thanks

Hi Simon!

Do you have TreeViewItem encoded set to False?
