How to Increase repeatcolumns of sub-category-grid

Hi,

I want to list 4 categories in a row using sub-category-grid.
Please let me know where i need to change this so that 4 categories under Computers are shown in horizontal.

I tried to change following lines in Templates/Categories/ProductsInGrid.ascx from
    <div class="sub-category-grid">
        <asp:DataList ID="dlSubCategories" runat="server" RepeatColumns="2" RepeatDirection="Horizontal"
To
    <div class="sub-category-grid">
        <asp:DataList ID="dlSubCategories" runat="server" RepeatColumns="4" RepeatDirection="Horizontal"

But this didnot work for me.
Would appreciate if anyone could help me.

Thank you,
KK

you've done the correct thing:

you've edited the category template but you also need to edit ( from store admin ) which template that category uses - out of the box, there are three category templates

in admin, edit

categories-->desktops-->

look for the drop down list next to 'Template'  and select Products In Grid


save and view your category
