I have a Dropdown box that I want to bind with GridView. But the Id of the DropDownList Model is of type string. And I cannot add string as an optional parameter in my SelectMethod of the GridView.
DropDown Model & Code :
public class ProjectViewModel
{
public string ProjectId { get; set; }
public string ProjectName { get; set; }
}
.aspx
<asp:DropDownList runat="server" AutoPostBack="true" ID="DisplayProject"
ItemType="VincitoreCRMApplication.Models.ProjectViewModel"
DataValueField="ProjectId"
DataTextField="ProjectName"
SelectMethod="GetProjects"
AppendDataBoundItems="true">
<asp:ListItem Text="All" Value="" />
</asp:DropDownList>
...
