In my main page (call it index.aspx
) I call
<%Html.RenderPartial("_PowerSearch", ViewData.Model);%>
Here the viewdata.model != null
When I arrive at my partial:
<%=ViewData.Model%>
Says viewdata.model == null
What gives?!
Have you tried just passing in ViewData instead of ViewData.Model? This is an abridged version what I use in my helpers (shamelessly stolen from the Storefront series):
/// <summary>
/// Renders a LoggingWeb user control.
/// </summary>
/// <param name="helper">Helper to extend.</param>
/// <param name="control">Type of control.</param>
/// <param name="data">ViewData to pass in.</param>
public static void RenderLoggingControl(this System.Web.Mvc.HtmlHelper helper, LoggingControls control, object data)
{
string controlName = string.Format("{0}.ascx", control);
string controlPath = string.Format("~/Controls/{0}", controlName);
string absControlPath = VirtualPathUtility.ToAbsolute(controlPath);
if (data == null)
{
helper.RenderPartial(absControlPath, helper.ViewContext.ViewData);
}
else
{
helper.RenderPartial(absControlPath, data, helper.ViewContext.ViewData);
}
}
Note that I pass in the current ViewData and not the Model.
This is untested:
<%=Html.RenderPartial("_ColorList.ascx", new ViewDataDictionary(ViewData.Model.Colors));%>
Your control view is expecting view data specific to it in this case. If your control wants a property on the model called Colors then perhaps:
<%=Html.RenderPartial("_ColorList.ascx", new ViewDataDictionary(new { Colors = ViewData.Model.Colors }));%>
