Pb with skinID in templated columns having DataBinder.Eval

[WT]

Hello,

I have a usercontrol loaded in a page with a theme.

This usercontrol contains columns template with hyperlinks, with skinID.

The columns are not displayed, seems thta there is some not traceable
exception triggered and the all binding is stopped.

But this same named skinid is working for hyperlinks outside templates.

Is it a knwn problem ?

Thanks for help.

CS

Here is a sample of my code:

<asp:datagrid id="myDataGrid " runat="server" width="100%"
AutoGenerateCol umns="False" EnableViewState ="False" AllowSorting="T rue">
<Columns>
<asp:TemplateCo lumn>
<ItemTemplate >
<asp:HyperLin k Text="<%$ Resources:Resou rcesGen,EDIT %>"
SkinID="editHyp erLink" NavigateUrl='<% #
BuildUrl(Config .ModulesPath+"/Cont/ContEdit.aspx", PageNum,"ItemNu m=" +
DataBinder.Eval (Container.Data Item,"ItemNum") )%>' Visible='<%# IsEditable
%>' runat="server" />
</ItemTemplate>
</asp:TemplateCol umn>

Thanks for answer.

I will ask for a small sample. It's difficult because we use a huge library
which contains all logic with custom controls, DB access, UI, etc...

We have also noticed that inserting a div around the hyperlink drives it to
run normally ??????
In fact problem seems to be in the usage of SkinID inside the hyperlink when
in a datalist item.

Without the div, hyperlink is not rendered totally we only get the <a with
the href='...' then nothing more: the </ais missing and the <imgnormally
rendered inside with a path to the image specified in the skinid is not
there.
When the div is there everything is rendered correctly ????

CS
Any idea ?

Hi CS,

Thanks for the update. Do you have a reproducible project to show the
problem of the ImageButton? Thanks.

Hi CS,

I think we can use some mock data to test the skin behavior.

Sorry I cannot tell exactly what might be wrong at current moment without
full code listing.

Hello Walter,

Adding the virtual Render method in our code, with a try-catch around
base.Render we get an exception with:

Cannot use a leading .. to exit above the top directory.

This seems to be generated by the skinId, when the hyperlink try to add its
image in the anchor.
I still dont understand why, and why when adding a div around this, all
seems to work....I have checked, there are no reasons for 'a leading .. to
exit above the top directory' in our skinid and in the current server
executing path ?????,

And I don't understand why the exception is not sent to our Application
Error Handler in global.asax, under normal conditions all our exceptions
catching are traced and rethrow to reach global handler.
And I get no trace ???? the Page.render continue its work, missing some
parts of the rendering (no closing </a>).
Is it possible that .net catches something from the sending of Render
without any warning or trace?

Walter, it looks like a MS bug.

In fact when we set a SkinID in an hyperlink used in a Datalist, it appeard
that the path for the imageurl, comming from the skin, is set with a path
like ~/App_Themes/MyTheme/MyImage.gif.

We get this using the ItemDataBound event and tracing the imageurl for the
Hyperlink.

Until now this is not a problem, but it appears that during Render, the
private methods
System.Web.UI.C ontrol.ResolveC lientUrl(String relativeUrl)
expecting a relative url, transforms this in
.../../App_Themes/MyTheme/MyImage.gif
- this could be normal as the usercontrol being rendered is in an url 2
levels under the web site path-

then System.Web.Util .UrlPath.Reduce VirtualPath(Str ing path) discovers that
we are trying to get beyond the site root url and throw an exception and the
code for hyperlink is not rendered.

So we transformed the imageurl set from the skin, removed the ~ and Render
runs normally.

Should we have to do this everytime, what could be the reason for this ?

ReduceVirtualPa th seeems to be failing in some special conditions ???

Thanks for help.

Hi CS,

Things are a little complicated, could you please put up a reproducible
project and send it to me? My email address is in my signature below. Thank
you very much for your effort.
