Hi...

I'm populating a treeview from a relational, nested dataset.

But I would like to place an image (reds, yellows or green dots .gif) on the side of each item from Level 1, indication whether they are active, inactive or waiting.

is it possible with DataBind or I have to do nested loops???

tks in advance,
Christiano.

Hi,

I believe you can do that with DataBinding object. A DataBinding object maps a data field to a menu item property. You can find more information on DataBinding object at here:

Thanks!

If I got you right, you want to change displayed Node image depending on Node status: Active, Inactive or Wait.

you can achieve that in different ways, but the simplest approach that crossed my mind at moment is the following:

1) Store the status as Node's Value, something like:
Code: Visual Basic.NET 
myNode.Value = "Active"


2) Check Node status and set Node's ImageUrl property accordingly.
Here, you might need a conditional loop or Case block to iterate through status possible values.

To set Node's ImageUrl, do something like:
Code: Visual Basic.NET 
myNode.ImageUrl = "green.gif"


I will leave iteration code to you to attempt.


Hope this helps.

Tks a lot both for the help...

Finally I've figured out how to do this...

Added a binding control to the treeview with this code:
Code: Visual Basic.NET 
binding = New DataBinding
binding.DataField = "StatImag"
binding.Property = "ImageUrl"
tvModelos.Bindings.Add(binding)


And it worked out as should.

the only thing, is that i must get the full path from the database. But that's no big deal...
