Limit asp:label Databinder.Eval characters displayed

[John]

Hello
I want to use the same data string (memo) to populate a "summary" asplabel. After the summary there would be a + "..." and a "see more..." link to the "complete" string contents - for the summary (e.g. aspLabel ID="lblSName" text=Databinder.Eval(Container.Dataitem,"Description") Runat="server"aspLabel) I need to limit the number of characters displayed.

Any ideas?
Thanks
John

I would try in this line...

1) Bind the Memo to 2 Lables . Label1 will be the summary and Label2 will be
the full text.
2) Use javascript to hide Label1 and show Label2 onmouseover / onclick on
"+...See more" on Label1. Hide Label2 and Show Label1 onmouseout of Label2

to trim the text to summary , implement a function in code behind

protected string TrimMemo(string Memo)
{
string Summary = Memo.SubString(1,100);
Summary += "<A HREF='javascript:ShowL2HideL1();' > +...See more </A>"
return(Summary);
}

Then call it during databinding.

aspLabel ID="lblSName"
text=TrimMemo(Databinder.Eval(Container.Dataitem,"Description"))
Runat="server"aspLabel

substring index out of range? this will cover your nuts

<asp:TemplateField HeaderText="Note" ItemStyle-Width="110">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem,"VoucherNote").ToString().Length > 20 ?
DataBinder.Eval(Container.DataItem, "VoucherNote").ToString().Substring(0,20) :
DataBinder.Eval(Container.DataItem,"VoucherNote").ToString().Substring(0,DataBinder.Eval(Container.DataItem,"VoucherNote").ToString().Length)%>
</ItemTemplate>
</asp:TemplateField>
