instead u reapter control use DataList. If u r using Datalist, its possible to change css dynamically.

You need a counter in the repeater. There is one:
<%# Container.ItemIndex + 1 %>
<%# Container.DisplayIndex+1 %>

(the +1 is because it starts counting at 0, and you want to start counting at 1)

Then you need a function to see if the number is divisible by 4. That can be done using the MOD (VB) operator, or whatever it is in C#. Ah, in C# it is the % operator.

And you need an conditional function, IIF() in VB. Find it yourself in C#.

<asp:repeater>
    <ItemTemplate>
        <div  class="<%#IIF((Container.ItemIndex + 1) MOD 4 = 0, "css_class_1", "css_class_2")%>">

        </div>
    </ItemTemplate>
</asp:repeater>

Thanks sybe,

do you know how to do this on itemdatabound event?

I.E

if (current item count % 4 == 1)
set css class?

so far i have this:
protected void rpProducts_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if ((rpProducts.Items.Count+1 % 4) == 1)
            {
                ProductBox1Control pbx = (ProductBox1Control)e.Item.FindControl("ctrlProductBox");
                pbx.CssClass = "categ_box nomrg_right";
            }

        }

but of course its wrong because its counting the total number of items

Soryy, but no. Can't help you with that. Maybe someone else can.

 

by: iziiziPosted on 2009-11-03 at 04:40:56ID: 25728311

got it

decimal c = (e.Item.ItemIndex + 1) % 4;

            if (c == 0)
            {
                ProductBox1Control pbx = (ProductBox1Control)e.Item.FindControl("ctrlProductBox");
                pbx.CssClass = "categ_box nomrg_right";
            }

thanks for your help sybe
