change Databinder.Eval expression during runtime

[rockyprince]

Hi all,

I have a datagrid like this:

----------------------------------------------------

<aspatagrid id="datagrid" runat="server" width="100%">
<Columns>
<asp:TemplateColumn HeaderText="Date">
<ItemTemplate>
<asp:Label Runat="server" ID="lblDate"><%# DataBinder.Eval(Container.DataItem,"Date","{0}")%></asp:Label>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</aspatagrid>
-------------------------------------------------------

Now, I also have two radio buttons, one to display the "Date" in US format, and the other to change it to UK format.

Is there a way I can change the 'DataBinder.Eval(...' expression in my code behind? to allow me to change the format character '{0}' to something else.

I have an alternative solution, where I use the following expression instead:

<%#getDate(DataBinder.Eval(Container.DataItem,"date").ToString())%>

...where getDate is a protected function, that formats the date depending on which radio button is checked.
This will work, but I was looking for something more pretty.

Thanks for any help,
Rocky

If you set your radio buttons to automatically post back, you could use FindControl to get a reference to the label, pass it's text to a function that will change the format, and then update the text to the new format.

Hi ca8msm, thanks for your reply.

the item in question is a column within a datagrid, if I use FindControl, it will be messy getting a handle on ALL the items on the datagrid that I need to reformat.

Maybe if I use the datagrid.ItemDataBound event, but I imagine it's no prettier than using the function call I've suggested in the original email.
