I'm trying to call this method:
RenderPartialExtensions.RenderPartial Method (HtmlHelper, String, Object, ViewDataDictionary)
http://msdn.microsoft.com/en-us/library/dd470561.aspx
but I don't see any way to construct a ViewDataDictionary in an expression, like:
<% Html.RenderPartial("BlogPost", Post, new { ForPrinting = True }) %>
Any ideas how to do that?
I've managed to do this with the following extension method:
public static void RenderPartialWithData(this HtmlHelper htmlHelper, string partialViewName, object model, object viewData) {
var viewDataDictionary = new ViewDataDictionary();
if (viewData != null) {
foreach (PropertyDescriptor prop in TypeDescriptor.GetProperties(viewData)) {
object val = prop.GetValue(viewData);
viewDataDictionary[prop.Name] = val;
}
}
htmlHelper.RenderPartial(partialViewName, model, viewDataDictionary);
}
calling it this way:
<% Html.RenderPartialWithData("BlogPost", Post, new { ForPrinting = True }) %>
You can do:
new ViewDataDictionary(new { ForPrinting = True })
As viewdatadictionary can take an object to reflect against in its constructor.
