Sharepoint - Setting PropertyBag values in SharePoint Online
Works for me with a couple small changes. Instead of manipulating the FieldValues
object, just manipulate the AllProperties
object directly. Also, set the value to a string, not an int:
web.AllProperties["allowdesigner"] = "0";
Here's the full helper method I use:
public static void AddWebProperty(ClientContext ctx, string propertyName, string propertyValue)
{
Web web = ctx.Web;
ctx.Load(web);
ctx.ExecuteQuery();
web.AllProperties[propertyName] = propertyValue;
web.Update();
ctx.ExecuteQuery();
}
Derek's answer solves problem for property bag in general, but there's also Site.AllowDesigner
property you could use for your specific case.
