Answer 1

Make these changes

Markup

1. Pass the clicked element as itself like toggleDiv(this)
2. Remove the id of the div

Sample Code

<ItemTemplate>
    <asp:Label ID="Label1" runat="server" Text='<%# Eval("CategoryName")%>'>
    </asp:Label>
    <br />
    <asp:LinkButton ID="LinkButton1" runat="server" 
            OnClientClick="javascript:toggleDiv(this);return false;">
        LinkButton</asp:LinkButton>
    <div style="background-color: blue; width: 150px; height: 150px; display: none;">
    </div>
</ItemTemplate>

JavaScript (Toggle the visibility of the element next to the element that's clicked)

function toggleDiv(elm) {
    $(elm).next().toggle('slow');
}

Whenever I need to execute JS from a Gridview I try to avoid using asp controls like LinkButton as they tend to cause a postback which you then need to prevent, which can be done, but I find it far easier to just embed a basic html button or img tag with an onclick set for your JS. No postback and no extra code to prevent a postback.

<asp:TemplateField>
  <ItemTemplate>
    <asp:Label ID="Label1" runat="server" Text='<%# Eval("CategoryName")%>'></asp:Label>
    <br />
    <button ID="LinkButton1" runat="server">Button Text</button>
    <div id="Shoow" runat=server style="background-color: blue; width: 150px; height: 150px; display: none;">
    </div>
  </ItemTemplate>
</asp:TemplateField>

Then in the OnRowDatabound event you do the following because runat="server" has been set:

dim btn as HtmlButton = e.Row.FindControl("LinkButton1")
dim div as HtmlContainer = e.Row.FindControl("Shoow")

dim js as String = String.Format("toggleDiv('#{0}')", div.UniqueID)
btn.Attributes.Add("onclick", js)

and the JS:

function toggleDiv(divId) {
  $(divId).toggle('slow');
}
