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.

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>

More on this subject, stillno solution: on the first display ( PostBack
false) the datagridrows are not display, but on the postback due to a change
in the sort column, miracle ! everything is displayed !
In complement I add that viewstate is off for the Grid and that in the
Page_Load event (set with a delegate in OnInit, and autoevenetwireu p=false)
is always binding the datagrid from the DB.
Onlychange is thta the sort event generates a seconjd binding ? Should I
bind twice when postback==false ?

I can't ask my users to do a postback :) ?
What could be the reason ?

Thanks for help.

Hi CS,

For such issue, I hope you understand that without complete reproducible
code or project, there's really not much I can do here to point out the
root cause. Therefore, would you please post more complete code here for
reference? Thank you.

Hi CS,

I can see your BindData has a try/catch block, check if there's any
exception when first loaded.

Here's my test code that works fine on my side:

<%@ Import namespace="Syst em.Data"%>
<%@ Control Language="C#" ClassName="WebU serControl" %>

<script runat="server">
private string BuildUrl(string url, string qs)
{
return url + "?" + qs;
}
private bool IsEditable
{
get { return true; }
}

protected void Page_Load(objec t sender, EventArgs e)
{
myDataList.Data Source = GetDataTable();
myDataList.Data Bind();
}

DataTable GetDataTable()
{
DataTable dt = new DataTable();
dt.Columns.Add( "ItemID", typeof(int));
dt.Columns.Add( "Question") ;
dt.Columns.Add( "CreatedDat e", typeof(DateTime ));

for (int i = 0; i < 10; i++)
{
dt.Rows.Add(i, "question " + i, DateTime.Now);
}
return dt;
}

</script>

<asp:DataList ID="myDataList " runat="server">
<SelectedItemSt yle BackColor="Gain sboro"></SelectedItemSty le>
<ItemTemplate >
<asp:HyperLin k SkinID="editHyp erLink" ID="HyperlinkIt em"
Text="Edit" runat="server" NavigateUrl='<% #
BuildUrl("/FAQsEdit.aspx", "ItemID=" +
DataBinder.Eval (Container.Data Item,"ItemID") )%>'
Visible="<%# IsEditable %>" />
<span class="normalBo ld">
<asp:Literal Text="FAQ" ID="Literal3"
runat="server"> </asp:Literal>:&n bsp;</span>
<asp:LinkButt on ID="LinkbuttonI tem" runat="server"
CausesValidatio n="False" CommandName="se lect"
Text='<%# DataBinder.Eval (Container.Data Item, "Question") %>'
title='<%# DataBinder.Eval (Container.Data Item, "CreatedDat e") %>'>

</asp:LinkButton>
</ItemTemplate>
</asp:DataList>

Hi CS,

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