using Eval ("ZZZ")

[Rick Mavrovik]

Hi,
I am using repeater bound to a dataset.
Within the repeater I have got ItemTemplate in which I am displaying data by
using
Eval("DataFieldName").

Does anyone know how can I perform any calculation in ItemTemplate on the
bound data..For instance. I need to display an image based on some rule like
if Eval("ThisField") is greater than Eval("ThatField").

Any clue?

Hi,

in addition to the solutions Milosz gave you, here's a third way: call a
code-behind method on the bound data.

<ItemTemplate>
<asp:Label runat="server" ID="lab"
Text='<%# MyMethod(Container.DataItem) %>'/>
</ItemTemplate>

and in the code behind:

protected string MyMethod (object DataItem)
{
DataRowView dr = DataItem as DataRowView;
if (dr == null)
return "";
return dr["Column1"].ToString() + dr["Column2"].ToString();
}

....or whatever you need to do there. You can also pass additional
parameters.

One additional solution -- add a column to your data which does the
calculation and then use that field name.
