Hi kevinf,
Set runat server attribute in the Anchor link. So that you can access Anchor Tag in code behind.
Then set the InnerHtml property.
HTML
<a id="lnkImport" runat="server" href="#about-section" class="nav-link fs mediaresize">
<em class="icon-import_contacts fs" style="margin-right: 5px;"></em>Import</a>
<asp:Button Text="Set" runat="server" OnClick="OnSet" />
Code
C#
protected void OnSet(object sender, EventArgs e)
{
lnkImport.InnerHtml = "<em class='icon-import_contacts fs' style='margin-right: 5px;'></em>Export";
}
VB.Net
Protected Sub OnSet(sender As Object, e As EventArgs)
lnkImport.InnerHtml = "<em class='icon-import_contacts fs' style='margin-right: 5px;'></em>Export"
End Sub
