I have div tags in my html code (see the code example bellow)

Now, I am trying to make them visible and invisible (based on criteria) in my asp.net code by doing this:

  div1.Style("Display") = True
        div2.Style("Display") = "none"

But it tells me that Div1 "is not declared."
 



<asp:Repeater ID="Repeater1" runat="server">
<%--                     <headertemplate>
                     
                     </headertemplate>--%>
                     <ItemTemplate>
                     <font size="2" <b><label style="padding-right:93px;">Category ID</label><%#Eval("Category_ID")%></font>                                                
                        <br />
                         <font size="2"  ><label style="padding-right:82px;">Category Path</label><%#Eval("Category_ID")%></font>
                        <br />
                        <font size="2"><label style="padding-right:126px;">Name</label><%#Eval("Category_Name")%></font>
                        <br />
                        <font size="2"><label style="padding-right:93px;">Description</label><%#Eval("Category_Description")%></font>
                       <br />
                        <font size="2"><label style="padding-right:67px;">Parent Category</label><%#Eval("Parent_Category_ID")%></font>
                       <br />
                               <div id="div1" runat="server">
                                      <asp:Label ID="lblNoMainImage" runat="server" Text="No Image"></asp:Label>
                                    </div>

                                    <div id="div2" runat="server">
                                         <asp:HyperLink ID="hlMainImageView2" NavigateUrl="javascript:OpenChild('main');"
                                             runat="server">View</asp:HyperLink>
                                            &nbsp;
                                      &nbsp;

                                    </div>  

                       <br />                                          
                      </ItemTemplate>
                   
                    </asp:Repeater>

Since the Divs are in a repeater control, they aren't listed in the Page.Controls collection.  Insteadm they are in the Repeater.Controls collections.  I suggest something like Repeater1.Controls.FindControl("div1").  I haven't tried this, but I'm sure its very close.

is
div1.Style("Display") = ""

Hi, first you have to use the css for creating the div design then after you have to set the visible property of div into your coding part.

How would i do that in conjunction with the find method...

simply doing this will not work:

 Repeater1.FindControl("div1")
        Repeater1.FindControl("div2")

        div1.Style("Display") = True
        div2.Style("Display") = "none"

try this :

Repeater1.FindControl("div1").Style("display") = "none"

However you may be better doing it in javascript.

A good artile for what you are trying to achieve :

If you want to use CSS to hide the control, then you could use:

Repeater1.FindControl("div1").Style("display") = "none";

Open in new window


If you don't want the server to send the control at all, then you would address the visible property in .Net, like so:

Repeater1.FindControl("div1").Visible = False;

Open in new window

Ah, right, sorry.  Try this:

Repeater1.FindControl("div1").Style["display"] = "none";

Open in new window


Style is a collection, not a method.
