Question

I searched throughout the website for the error

I am getting this error while binding a dropdown list.

DataBinding: ‘System.Char’ does not contain a property with the name “APPRAISER_ID”

Here’s my 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();

And in my webservice.

string strQ = "select employee_id,appraiser_id from kirti_pms_reporting where appraiser_id='" + varAppraiserId.ToString() + "'";

My Inline code for dropdown list is

<asp:DropDownList ID="ddlEmployee" runat="server" AutoPostBack="true"  CssClass="vlu">

What I missed here? The same code works fine in another aspx page.

Answer 1

The problem is that you bind a string to your DataSource

ddlEmployee.DataSource = DSEmployee.Tables[0].DefaultView.ToString();

And a string don’t have a property APPRAISER_ID.

select employee_id,appraiser_id from kirti_pms_reporting where appraiser_id='" + 
varAppraiserId.ToString() + "'";

Is not a good idea because you could run into SqlInjection.
