binding a value to a checkbox
 

Hello dotnet expert !!
I want to present as a checkbox the values -1 as true and 0 as false stored
in a table.
I got a Datalist and dragged a chekbok in the ItemTemplate section.
I link my data field to it. I compile but at execution time, I got
"Specified cast is not valid". Where can I associate the value -1 to true
and 0 to false ?
I did not find it in the properties.

Thanks for your help!!

<TD><asp:CheckBox id=chkAutreSourceEnergie runat="serveur" Texte="Autre

"Tables[Resultats].DefaultView.[0].Autre_Src_Energie")%>'>
</asp:checkBox></TD>

Re: binding a value to a checkbox
 

You need to do something like this:

CheckBoxItem.Checked = Convert.ToBoolean(value);

that will convert your value(which is -1 or 0) to a boolean.
