[Mono-dev] [PATCH] System.Web.Compilation.TemplateControlCompiler: Data-Binding Syntax: fixed Bind functions

[Igor Zalmanovich]

Tony,

 

It is other problem, not depended on my fix.

 

Please, open file in bugzila for this bug.

http://bugzilla.ximian.com/enter_bug.cgi?product=Mono%3A+Class%20Libraries

 

Meanwhile you can use "Eval" instead "Bind" for Repeater.

Igor,

Thanks!

My original aspx is a little complicated, so I wrote a simple test aspx (modified from mono test aspx file: web_repeater.aspx) which I attacked here. It runs fine in VS:

Country

Abbreviation

Continent

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

But got the following error under mono:


Bind expression not allowed in this context.


Description: Error processing request. 

Error Message: HTTP 500. Bind expression not allowed in this context. 

 

I also attacked my TemplateControlCompiler.cs here too. Please let me know if this test aspx file is Ok in your patcked mono.

 

Tony

	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.
