Hi I'm having a bit of an issue with a asp.net repeater
I'm building a categories carousel with the dynamic categories being output by a repeater.
Each item is a LinkButton control that passes an argument of the category id to the onItemClick handler.
a page variable is
set by this handler to track what the selected category id is....
public String SelectedID
{
get
{
object o = this.ViewState["_SelectedID"];
if (o == null)
return "-1";
else
return (String)o;
}
set
{
this.ViewState["_SelectedID"] = value;
}
}
problem is that i cant seem to read this value while iterating through the repeater as follows...
<asp:Repeater ID="categoriesCarouselRepeater" runat="server"
onitemcommand="categoriesCarouselRepeater_ItemCommand">
<ItemTemplate>
<%#Convert.ToInt32(Eval("CategoryID")) == Convert.ToInt32(SelectedID) ? "<div class=\"selectedcategory\">":"<div>"%>
<asp:LinkButton ID="LinkButton1" CommandName="select_category" CommandArgument='<%#Eval("CategoryID")%>' runat="server"><img src="<%#Eval("imageSource")%>" alt="category" /><br />
</div>
</ItemTemplate>
</asp:Repeater>
calling <%=SelectedID%> in the item template works but when i try the following expression the value of SelectedID returns empty..
<%#Convert.ToInt32(Eval("CategoryID")) == Convert.ToInt32(SelectedID) ? "match" : "not a match"%>
the value is being
set as follows...
protected void categoriesCarouselRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
SelectedID = e.CommandArgument);
}
Any ideas whats wrong here?
