title: Dropdownlist Reset SelectedValue
body: <p>I have a DropDownList connected to an ObjectDataSource. In my page load i set the selectedvalue to a specific value depending on the case. How can I in my method selectedindexchanged "reset" the selectedvalue so you still can choose from the other options? Or should I not use selectedvalue to set the defaultvalue of the dropdownlist?</p>
  
  <pre><code> &lt;asp:DropDownList ID="DropDownList" runat="server" DataSourceID="ObjectDataSource" DataTextField="Type" DataValueField="TypeId" 
      AutoPostBack="true" onselectedindexchanged="DropDownList_SelectedIndexChanged" &gt;
              &lt;/asp:DropDownList&gt;
  
  protected void Page_Load(object sender, EventArgs e)
  {
          int default = category.TypeId;
          DropDownList.SelectedIndex = default;
  
  }
  
  protected void DropDownList_SelectedIndexChanged(object sender, EventArgs e)
  {
  
      int id = int.Parse(DropDownList.SelectedValue);
      Session["id"] = id;
  }
  </code></pre>
