1 selected ites send 2 values in selectedValue

[Andy Green]

I have a DDT binding server side to Id & Name, I also have checkboxes

rdtLocation.DataSource = locations;
rdtLocation.DataTextField = "Name";
rdtLocation.DataFieldID = "Id";
rdtLocation.DataValueField = "Id";
rdtLocation.DataFieldParentID = "ParentId";
rdtLocation.DataSource = locations;
rdtLocation.DataBind();

With one selected item when I look at the selectedValue I get a comma separated list containing 2 instances of the id. ie - "2,2"

See attached screen shot.

Why is this and what is the fix.

Hello Andy,

I have tested different scenarios, but I was not able to replicate the issue with two duplicate ID values. Can you please provide some dummy data that replicates the issue and also the exact steps for reproducing it?

I am looking forward to your reply.

For now I have a fix for this, using LINQ to select distinct.

var location = rdtLocation.SelectedValue.Split(',').Select(int.Parse).Distinct().ToList();

Hi, I need to revisit this.

What I'm finding is that if I change selections, I get both in the SelectedValue, so no I cant use the LINQ above, as the ID's are different. I read somewhere that the control has to be Ajaxified to stop this but cant find it now.

Any ideas?

Hello Andy,

I'm sending a sample web site to demonstrate that the SelectedValue should correctly return only the values of the checked items single time. Alternatively, you can traverse the RadDropDownTree1.EmbeddedTree.CheckedNodes collection and extract the values manually.

I hope this will prove helpful.
