Calling Sitecore Controller rendering dynamically on the view(cshtml) file and passing rendering parameters

We can call the Controller renderings already created on a view file. In some scenarios we can not assign the rendering on the item (for ex wildcard scenarios where we need this rendering on specific item not all the items)

@Html.Sitecore().Rendering(itemid, new { DataSource = itmds.ID})

wher Datasource is

Item itmds = Sitecore.Context.Database.GetItem(“Path or Id or some Datasource field”);

Passing Rendering Parameters dynamically

Lets assume we are passing orientation and Background color with the Datasource where Orientation is passed as string.

Item itorient = Sitecore.Context.Database.GetItem( “Path or Id or some Datasource field” );
Item itbccolor = Sitecore.Context.Database.GetItem(” Path or Id or some Datasource field );

string Orient = string.Format(“Orientation={0}&Background Color={1}”, itorient.Name, itbccolor.ID);
