I have tried all the demos and examples and nothing has worked!
Markup:

Now, heres where it works and doesn't. If I have this line (similar for the second drop down): when I go into edit mode, the drop downs are populated with the current values which is a project requirement.  But when I click the 'Add new user', I get this error:

'cmbEdit_Rights' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

If I leave out the <%# Bind("UserLevel") %> I can insert and update, but I loose the requirement of displaying the current value which I need.


Please help asap!

Hello there,

I was referring telerik demo for such functionality - http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx

The only change is i am using treeview with checkbox in RadComboBox. I wanted to display checked items of combobox as comobobox text with comma on collapse.

How to do that?

Hi,
We have treeview with checkbox in combobox.We dont have any problem with chrome and firefox but combobox doesnt closed when we focused out of the control in IE.

<telerik:RadComboBox ID="cbxDepartments" runat="server" DataTextField="DEPNAME" DataValueField="DEPID"
                                ExpandAnimation-Type="None" CollapseAnimation-Type="None" OnClientDropDownClosing="OnClientDropDownClosing"
                                AllowCustomText="True" EmptyMessage="-- seçiniz --">
                                <ItemTemplate>
                                    <div id="div1">
                                        <telerik:RadTreeView ID="tvDepartments" runat="server" DataTextField="DEPNAME" DataValueField="DEPID"
                                            DataFieldParentID="SUBDEPID" DataFieldID="DEPID" Height="140px" CheckBoxes="true">
                                        </telerik:RadTreeView>
                                    </div>
                                </ItemTemplate>
                                <Items>
                                    <telerik:RadComboBoxItem Text="" />
                                </Items>
                                <ExpandAnimation Type="Linear"></ExpandAnimation>
                                <CollapseAnimation Type="None"></CollapseAnimation>
                            </telerik:RadComboBox>

 <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            function OnClientDropDownClosing(sender, args) {
                //            if (args.get_node().get_level() == 0)
                //            {
                //                args.set_cancel(true);
                //            }
                //            else {
                var item = sender.get_items().getItem(0); // Get the first RadComboBoxItem
                var treeView = item.findControl('tvDepartments'); // Find your RadTreeView
                var checkedNodes = treeView.get_checkedNodes(); // Retrieve the checked items in the RadTreeView

                var newText = '';
                checkedNodes.forEach(function (node) {  // Loop through the checked nodes. Requires jQuery!
                    if (newText != '') { newText += ', '; }
                    newText += node.get_text();
                });
                var comboBox = $find("<%= cbxDepartments.ClientID %>");
                comboBox.set_text(newText); // Set the RadComboBox text
                if ($.browser.msie) { // IE sometimes takes two tries for it to respond to new text
                    comboBox.set_text(newText);
                    //                }
                }
            }
        </script>

I have been through your sampels http://demos.telerik.com/aspnet-ajax/window/examples/browserdialogboxes/defaultcs.aspx  and I have no issues getting these to work.  But I have been unsuccesful in getting the values of the confirm in my serverside code behind.  Basically im trying to fire one server side function if yes/true and  a different server side sub if no/false.  In your samples you are firing a javascript to display the result, thats fine but unfunctional for my application. 

Hello,

I have several RadComboBoxes that interact with each other using client-side methods and requesting the items on demand, like here: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx
This works well, but when I need the SelectedValue it's always empty.

Can anyone help me please? (I don't know what I'm doing wrong...)

Here I put the code used:

RadComboBoxes

Scripts

Page_Load (server-side)

Rest of functions

When I try to get cboLocalidadT.SelectedValue in function LoadNombresVia

Thank you very much for your help!!

I have this RadTextBox:

Note the parenthesis on

ClientEvents OnValueChanged="onValueChanged()" />

If I remove the parenthesis from the function call, the function is not executed. If I keep the parenthesis, the function is executed (see below), but the parameters are not passed.

<script type="text/javascript">

 

        function onValueChanged(sender, args) {

 

            if (args.get_oldvalue != args.get_newvalue) {

 

                thisDiv = $get("<%= div_projectsAssigned.ClientID %>");

                esteDiv = "#" + thisDiv;

                animateDiv(thisDiv);

            }

        }

 

        function animateDiv(divToAnimate) {

 

            for (i = 1; i <= 3; i++) {

 

                $(divToAnimate).animate(

                    { "opacity": "0.15" },

                    "slow");

 

                $(divToAnimate).animate(

                    { "opacity": "1.00" },

                    "slow");

            }

        }

 

    </script>

I need the parameters to check if the value in the RadTextBox has changed, and if so, make an amimation.
Any idea about why the parameters are not being passed?

With several detail tables at the same level, is there a way to bind each table to a source programmatically? Each one will be calling the same stored procedure, but with a different parameter value.

I'd love to do something like this:
DetailTable1.DataSource = spFillMe 1
DetailTable2.DataSource = spFillMe 2
DetailTable3.DataSource = spFillMe 3

Also, because connection strings are managed in my environment, I can't point SqlDataSources to a table or string on the front page.

Is there any way I can set focus on the textelement in the combobox from client side. I tried setting .focus() method on the client side, but it only keeps the combobox focused, and when i press any key the input text element, inside the combobox does not get focus. Is there any other way to get focus on that.

Hi ,

I need a tooltip to be displayed when I hover mouse over LinkButton.
The tooltip required should have blue border and we need to change font color and size as well.

I have tried using :


And :


But the styles are not effecting the Tooltip .
Not sure for the solution ,I also tried using codebehind and using a separate stylesheet. But it didn't help.

Please provide me a solution for implementing this.
