Hi! I am trying to create HelpDesk functionality using RadWizard to create new incident.

On first step user selects incident category from RadComboBox (hardware problems, software etc)

Then i dynamically create 2 new steps with a different markup depending on combobox selected value.

Everything works fine until user goes back to first step and selects new RadComboBox value.

Functionality allows to do such thing. And i have to delete next steps and create new ones with other markup.

I found simple solution to disable RadComboBox, but it seems to be uncorrect solution. Can you help me?

Here is my code

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
     
        <asp:ScriptManager runat="server" />
        <div>
 
            <script type="text/javascript">
            </script>
            <telerik:RadWizard runat="server" ID="RadWizard1" Height="360px"
                 OnNextButtonClick="RadWizard1_NextButtonClick" OnWizardStepCreated="RadWizard1_WizardStepCreated" DisplayCancelButton="True">
                <WizardSteps>
                    <telerik:RadWizardStep ID="RadWizardStep1" runat="server" Title="Book Group Vacation" StepType="Start" DisplayCancelButton="True" >
                        <telerik:RadComboBox ID="RadComboBox1" Runat="server" AutoPostBack="False">
                            <Items>
                                <telerik:RadComboBoxItem runat="server" Text="1" Value="1" />
                                <telerik:RadComboBoxItem runat="server" Text="2" Value="2" />
                                <telerik:RadComboBoxItem runat="server" Text="3" Value="3" />
                            </Items>
                        </telerik:RadComboBox>
                        <br/>
                        <label>ComboBox Value Is </label><span id="CB" runat="server"></span>
                         
                    </telerik:RadWizardStep>
                </WizardSteps>
            </telerik:RadWizard>
        </div>
    </form>
</body>
</html>

            string[] labelTitle = new string[] { "First Name:", "Second Name:", "Third Name:" };

                e.RadWizardStep.Controls.Add(rcbFirstName);
                e.RadWizardStep.Controls.Add(new Literal() { Text = "<br />" });
            }
            RadTextBox rcbVal = new RadTextBox();
            rcbVal.LabelWidth = Unit.Pixel(150);
            rcbVal.Width = Unit.Pixel(500);
            rcbVal.Label = "ComboBoxValue";
            rcbVal.Text = RadComboBox1.SelectedValue.ToString();
            e.RadWizardStep.Controls.Add(rcbVal);
            e.RadWizardStep.Controls.Add(new Literal() { Text = "<br />" });
 
            RadButton rbRemove = new RadButton();
            rbRemove.Text = "Remove Person";
            rbRemove.Click += rbRemove_Click;
            e.RadWizardStep.Controls.Add(rbRemove);
        }
    }
    protected void RadWizard1_NextButtonClick(object sender, WizardEventArgs e)
    {
        RadWizard wiz = (RadWizard)sender;
        
        Response.Write(wiz.WizardSteps[e.CurrentStepIndex].ID);
        Response.Write(wiz.WizardSteps[e.NextStepIndex].ID);
    }

Hello,

Disabling RadComboBox seems like a legit solution. You may also check if the steps are already added to the control before adding them so you don't duplicate them.
