The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Unable to reset Ajax Combobox control at runtime

Asked by lffit in Asynchronous Javascript and XML (AJAX), Active Server Pages (ASP), .NET Framework 3.x versions

Tags: ASP .Net, AJAX, VB, Ajax Control Toolkit

Currently I have two Combobox controls. Both have a static list of selections as follows:


                        <cc1:ComboBox ID="TypeCB" runat="server" RenderMode="Block">
                            <asp:ListItem Selected="True" Value="0">--Select--</asp:ListItem>
                            <asp:ListItem>a</asp:ListItem>
                            <asp:ListItem>b</asp:ListItem>
                        </cc1:ComboBox>
         
                        <cc1:ComboBox ID="SelectCB" runat="server" RenderMode="Block"
                            AutoPostBack="True" EnableViewState="False">
                            <asp:ListItem Selected="True" Value="0">--Select--</asp:ListItem>
                            <asp:ListItem>1</asp:ListItem>
                            <asp:ListItem>2</asp:ListItem>
                        </cc1:ComboBox>


During runtime, I want both Combobox's to reset their displayed values to "--Select--" whenever the second Combobox "SelectCB" throws a index changed event. I'm using vb .net and I try to change the SelectedIndex or SelectedValue properties but they simply aren't changing from the selected values. Being a relative VB newbie I'm unsure what piece of this I'm missing.

My only real goal is to reset the controls back to their default settings. How can I accomplish this?
