Text Box Needs to Display the Selection from the Dropdown Box

need my text box or some text somewhere on my form to display the value selected from my dropdown box.

Example - if an Author's genre of Fiction is selected, the textbox should display Fiction. How do I do this?

I can not use the PageLoad event because that event hides some other fields on the page. I think I need to include something in the selectedindexchange event.

Here is my code:

protected void AuthorsList_SelectedIndexChanged(object sender, EventArgs e) 
    { 
  
  
  
    } 

Open in new window

asp:DropDownList runat="server" ID="lbAuthorsList"  
       style="float:left;" DataSourceID="odsAuthorsList"  
       DataTextField="DisplayName" DataValueField="AuthorName"  
       onselectedindexchanged="AuthorsList_SelectedIndexChanged"  
       AutoPostBack="true" AppendDataBoundItems="true" > 
</asp:DropDownList>    
  <asp:TextBox id="tb4" Text="Hello World!" runat="server"  
        ondatabinding="AuthorList_SelectedIndexChanged" /> 
  
 <asp:ObjectDataSource ID="odsAuthors" runat="server"  
            SelectMethod="GetAuthorsGenresList" TypeName="GenreSelection"> 
        </asp:ObjectDataSource>

The selected Index changed event will allow you to do what your asking and I see AutoPostBack is already set to true.  If you are selecting Fiction from the drop down the code should be something like

tb4.Text = AuthorsList.Text;
