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.

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.
