EditUsing ComposeXhtml in C# and Visual Basic.NET
EditBackground
The code snippets below are used to feed the autocompleter with items based on what you type in. The ComposeXhtml function uses anonymous delegates which is only supported in C# and not VB.NET. Optionally you could split out the code in a separate function, but if you need additional data to construct the items it get's more difficult.
In the VB.NET code sample below we show you how you could accomplish using the XhtmlTagFactory to render xhtml compatible string to be used in literals anyway.
EditC# Code
private System.Web.UI.Control CreateItem(FileInfo inf)
{
System.Web.UI.WebControls.Literal lit = new System.Web.UI.WebControls.Literal();
lit.ID = inf.Name.Replace(".", "_");
lit.Text = ComposeXhtml.ToString(
delegate(XhtmlTagFactory create)
{
using (create.Div().SetStyle("float:left;padding-right:5px;"))
{
using (create.Img(null, null, "media/contentImages/ajaxian.gif", "")) { }
}
using (create.B().WriteContent(inf.Name.Replace(".aspx", ""))) { }
using (create.Br()) { }
using (create.A(null, null, inf.Name).WriteContent(inf.Name)) { }
});
return lit;
}
EditVisual Basic.NET Code
Private Function CreateItem(ByVal inf As FileInfo) As LiteralControl
Dim literal As New LiteralControl
Using writer As New StringWriter
Dim factory As New XhtmlTagFactory(writer)
CreateItem(factory, inf)
literal.ID = inf.Name.Replace(".", "_")
literal.Text = writer.ToString()
End Using
Return literal
End Function
Private sub CreateItem(ByVal create As Gaia.WebWidgets.HtmlFormatting.XhtmlTagFactory, _
ByVal inf As FileInfo)
Using create.Div().SetStyle("float:left;padding-right:5px;")
Using create.Img(Nothing, Nothing, "media/contentImages/ajaxian.gif", String.Empty)
End Using
Using create.B().WriteContent(inf.Name.Replace(".aspx", ""))
End Using
Using create.Br()
End Using
Using create.A(Nothing, Nothing, inf.Name).WriteContent(inf.Name)
End Using
End Using
End Sub
EditAdding Directly To Page
Here we use the ComposeXhtml directly to add content to the page.
C# Codebehind
protected void Page_Load(object sender, EventArgs e)
{
Literal lit = new Literal();
lit.Text = Gaia.WebWidgets.ComposeXhtml.ToString(
delegate(Gaia.WebWidgets.HtmlFormatting.XhtmlTagFactory create)
{
// We can store a reference to the Tag created by the creator like this
using (Gaia.WebWidgets.HtmlFormatting.Tag div = create.Div())
{
div.SetStyle("border:solid 1px Black;padding:5px;width:100px;");
div.WriteContent("Hello Ajax World");
using (create.Br()) { }
// Or we can do everything "inline" like we do here;
using (create.A(null, null, "http://www.google.com")
.SetStyle("text-decoration:none;color:orange;")
.WriteContent("Go to Google"))
{ }
}
});
Form.Controls.Add(lit);
}
HTML Output
Which ends up like this in the browser
