Replace text of ASP Literal in Code Behind

Question

I'm new to ASP and was hoping to get some guidance on how to make my literal accessible in my Code Behind and then change it to the text of a passed in parameter.

I have an resources.ascx file that displays a list of people (pulled from a database). That is working fine and it looks something like this:

Full name

T: (888-888-8888)

F: (888-888-8888)

The problem, however, is that I now want it conditionally say "Toll Free" instead of "F:" for one page.

In the people.aspx page, I'm passing in "Toll Free" to the resource:

<%@ Register Src="~/UserControls/resources.ascx" TagName="Resources" TagPrefix="ucResources" %> <ucResources:Resources ID="Resources1" FaxNumberAlias="Toll Free" runat="server" />

resources.ascx The repeater outputs all the people from the database to the page.

<asp:Repeater ID="Repeater1" runat="server"> <ItemTemplate> <div class="sectioncontent"> <b><%#Eval("EmployeeFirstName")%> <%#Eval("EmployeeLastName)%></b> T: <%#Eval("Phone")%> <br> <asp:Literal runat="server" ID="FaxNumberLabel">F:</asp:Literal> <%#Eval("Fax")%><br> </div> <br /> </ItemTemplate>

In the resources.ascx.vb file, I wanna do something like this but FaxNumberLabel (the literal I declared in resources.ascx) isn't accessible or hasn't been declared.

Public Property FaxNumberAlias() As String Get Return _FaxNumberAlias End Get Set(ByVal value As String) _FaxNumberAlias = value End Set End Property Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not String.IsNullOrEmpty(_FaxNumberAlias) Then FaxNumberLabel.Text = _FaxNumberAlias End If PopulateRepeater() End Sub

What am I missing that connects the literal to the code behind?

The problem is that the Literal is inside a Repeater so you may potentially have lots of them. The best way is to access them inside the OnDataItemBound event of your repeaters:

Protected Sub Repeater1_OnDataItemBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs) Handles Repeater1.OnDataItemBound If (e.Item.ItemType = ListItemType.Item) Or _ (e.Item.ItemType = ListItemType.AlternatingItem) Then Dim litFaxNumberLabel As Literal = e.Item.FindControl("FaxNumberLabel") litFaxNumberLabel.Text = _FaxNumberAlias End If End Sub

Note: Excuse any bad syntax, it's been over 4 years since I touched VB!

Thanks! I found somewhat of an answer with more searching but didn't completely solve it until I got your answer. I was missing the Handles Repeater1.ItemDataBound part and I was having trouble figuring out where RepeaterItemEventArgs comes from.

You can simply use like this -

 protected void DataDisplay_ItemDataBound(object sender, RepeaterItemEventArgs e) { if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) { LinkButton lit = (LinkButton)e.Item.FindControl("LinkButton2"); if (lit.Text == "0") { int a = Convert.ToInt32(lit.Text); if (a == 0) { if (a == 0) { lit.Text = "Your Text"; } } } } }

In my case, I am using a button (btnRedirect) in each row.

 RepeaterItem item = btnRedirect.NamingContainer as RepeaterItem; var type = item.FindControl("IdUsed") as Literal; var literalValue = type.Text;
