Hi, Tony,

 

Please send the original aspx file.

 

This will help me to analyze the source of the problem.

Here is my code generated :

Line 743:         public void __DataBind__bctrl_123(object sender, System.EventArgs e) {
Line 744:             System.Web.UI.WebControls.FormView Container;
Line 745:             System.Web.UI.DataBoundLiteralControl target;
Line 746:             target = ((System.Web.UI.DataBoundLiteralControl)(sender));
Line 747:             Container = ((System.Web.UI.WebControls.FormView)(target.BindingContainer));
Line 748:             target.SetDataBoundString(0, System.Convert.ToString( Bind("title") ));
Line 749:         }

	Igor,

	 

	After put this patch in my mono-1.1.17 (only with few other patches), I still get the Compilation Error for "Bind" fuction call. The same code works under VS 2005.

	Did I miss something?

	Thanks!

		This is the patch to fix Bind functions (Data-Binding Syntax).
		
		At run time, the Bind method calls the Eval method, if there is DataItem
		!= null to bind to.
		If there is DataItem == null (like InsertItemTemplate in FormView) Bind
		method don't raise exception and works properly to extract data from
		bounded controls on postback.
		
		See code generated by dotnet:
		
		public void @__DataBinding__control22(object sender,
		System.EventArgs e) {
		System.Web.UI.WebControls.CheckBox
		dataBindingExpressionBuilderTarget;
		System.Web.UI.WebControls.FormView Container;
		dataBindingExpressionBuilderTarget =
		((System.Web.UI.WebControls.CheckBox)(sender));
		Container =
		((System.Web.UI.WebControls.FormView)(dataBindingExpressionBuilderTarget
		.BindingContainer));
		if ((this.Page.GetDataItem() != null)) {
		
		#line 62 "C:\www\Menu\FormView.aspx"
		dataBindingExpressionBuilderTarget.Checked =
		((bool)(this.Eval("IsPublic")));
		
		#line default
		#line hidden
		}
		}
		
		
		Please review.
		
		Igor.
