I am using RadTreeDropdown on a page to display hierarchical data with checkboxes with Multiple nodes selection. When I checked a parent node (let us Node1) and it has two other child nodes (Node2,Node3), then it automatically selects the child nodes, but in the dropdown text it is just showing the parent node text and not showing child node text in Chrome. It is just showing ;;;;; in place of node text.

It is working fine with other browsers.I am using Chrome latest version i.e. Version 31.0.1650.57 m.

Please help. Thanks in advance.

Hi Lokesh,

Unfortunately I couldn't replicate the issue at my end. Please have a look into the following sample code which works fine at my end.

ASPX:
<telerik:RadDropDownTree ID="RadDropDownTree1" runat="server" DataSourceID="SqlDataSource2"
    DataFieldID="id" DataFieldParentID="parentid" DataTextField="text" CheckBoxes="CheckChildNodes">
</telerik:RadDropDownTree>
<telerik:RadButton ID="RadButton1" runat="server" Text="GetCheckedItems" OnClick="RadButton1_Click">
</telerik:RadButton>

C#:
protected void RadButton1_Click(object sender, EventArgs e)
{
    // accessing the selected text of raddropdowntree
    string text = RadDropDownTree1.SelectedText;
}

Thanks,
Princy.

Try the same with Checkbox="Tristate" option. You will see the issue on Chrome.

Hi Lokesh,

Unfortunately I couldn't replicate the issue with the "Tristate" option also. Please provide your code for further help and please mention your telerik version also.

Thanks,
Princy.

I think it is happening when I am adding this script on OnClientEntryAdding client event. I am using this

function OnCustomerClientEntryAdding(sender, args) {

var tree = $get("<%=_customerOfficeRadDropDownTree.ClientID %>");

var emtree = tree.control.get_embeddedTree();

//Expand the Child Node

var node1 = emtree.findNodeByText(args.get_entry().get_text());

if (node1.get_nodes() != null) {

        node1.expand();

    }

}

 

Can you help fixing this one. Thanks

Hello,

Please use this workaround in order to avoid this behavior:

//JavaScript
function OnCustomerClientEntryAdded(sender, args) {
    var tree = sender.get_embeddedTree();
    //Expand the Child Node
    var node1 = tree.findNodeByText(args.get_entry().get_text());
 
    if (node1.get_nodes().get_count() > 0) {
 
        window.setTimeout(function () {
            node1.expand();
        }, 200);
    }
}
