Question

I have List view – (

name: ListViewName

), with some labels inside it, the ID (name) of the label:

Biglbl

.. big because its include some links and titles.

there is one more label in name:

lblCatName

which return the category name.

I want to check each list view item – what is name (let’s say – “TEST”) and hide or display some labels or change HyperLink navigateUrl.

aspx:

 <asp:ListView ID="ListViewName" OnItemDataBound="ContactsListView_ItemDataBound" runat="server">
        <ItemTemplate>

        <asp:Label Visible="true"  ID="lblCName" Text='<%# Eval("CatName") %>' runat="server" > </asp:Label>

  <asp:Label runat="server" id="lblCName" Visible="false" />
              <div style=".....">

       ...............


         <asp:HyperLink ID="HyperLink4" runat="server" 
      NavigateUrl='<%# "bla.aspx?Id=" + Eval("id").ToString() %>'> 


                  </asp:HyperLink>

         <asp:HyperLink ID="HyperLink7" runat="server" 
      NavigateUrl='<%# "bla.aspx?Id=" + Eval("CatId").ToString() %>'>  <img src="images/btblue.png" /> </asp:HyperLink>

    </asp:Label>  

    </div>


        </ItemTemplate>
        </asp:ListView>

I have the C# code behind:

protected void ContactsListView_ItemDataBound(object sender,ListViewItemEventArgs e)
{
            foreach (ListViewItem item in ListViewName.Items)
        {

            Biglbl = (Label)e.Item.FindControl("Biglbl");
            Label lblCName = (Label)e.Item.FindControl("lblCatName");

            HyperLink Link = (HyperLink)e.Item.FindControl("HyperLink4");
            HyperLink Link2 = (HyperLink)e.Item.FindControl("HyperLink7");

            if (lblCatName.ToString() == "TEST")
            {
                Biglbl.Visible = true;
                Link.NavigateUrl = "blabla";
                Link2.NavigateUrl = "blabla";
            }
            else
            {
                Biglbl.Visible = false;
                Link.NavigateUrl = "aaaa";
                Link2.NavigateUrl = "aaaa";
            }

        }
}

I don’t know how to use the foreache for my needs here.

What i need to do (i think the if and the findcontrol’s are fine.. i need to do what to change in the foreac.

Answer 1

foreach (ListViewItem item in ListViewName.Items)
{
  // Code goes here.
}

EDIT: I see the question now shows you using ItemDataBound. This will pass you each ListViewItem as it is bound so there is no need to do a for each loop.

You can simply cast the sender to that type

ListViewItem item = (ListViewItem)sender;
