title: DataBinding: 'System.Char' does not contain a property with the name
body: <p>I searched throughout the website for the error</p>
  
  <p>I am getting this error while binding a dropdown list.</p>
  
  <blockquote>
    <p>DataBinding: 'System.Char' does not contain a property with the name "APPRAISER_ID"</p>
  </blockquote>
  
  <p>Here's my code:</p>
  
  <pre><code>DataSet DSEmployee = new DataSet();
  DSEmployee = ws_service.GetReportingDtl(user);
  ddlEmployee.DataTextField = "APPRAISER_ID";
  ddlEmployee.DataValueField = "APPRAISER_ID";
  ddlEmployee.DataSource = DSEmployee.Tables[0].DefaultView.ToString();
  ddlEmployee.DataBind();
  </code></pre>
  
  <p>And in my webservice.</p>
  
  <pre><code>string strQ = "select employee_id,appraiser_id from kirti_pms_reporting where appraiser_id='" + varAppraiserId.ToString() + "'";
  </code></pre>
  
  <p>My Inline code for dropdown list is</p>
  
  <pre><code>&lt;asp:DropDownList ID="ddlEmployee" runat="server" AutoPostBack="true"  CssClass="vlu"&gt;
  </code></pre>
  
  <p>What I missed here? The same code works fine in another aspx page.</p>
