Microsoft has a nice collection of controls bundled into a package called "IE Web Controls". Except for the fact that they are fully unsupported some controls are very handy.

I have used the TreeView in a custom WebPart and had some difficulty setting the styles. It seems you have to set the styles DefaultStyle, HoverStyle and SelectedStyle. The DefaultStyle is used when no action takes place, the HoverStyle is set when you hover with your mouse over an item and the SelectedStyle is the style of a selected item. Here are two examples of setting the style in a TreeView.

<mytree:treeview runat="server" 
   ID="tvwResources" 
   defaultStyle="font-family:Verdana,Arial,Sans-serif;color:#000000;font-size:11px;" 
   hoverStyle="font-family:Verdana,Arial,Sans-serif;color:#000000;font-size:11px;" 
   selectedStyle="font-family:Verdana,Arial,Sans-serif;color:#000000;font-size:11px;>
</mytree:treeview>

Or programmatically

mytree.DefaultStyle["font-family"] = "Verdana,Arial,Sans-serif";
mytree.DefaultStyle["color"] = "#000000";
mytree.DefaultStyle["font-size"] = "11px";

mytree.HoverStyle["font-family"] = "Verdana,Arial,Sans-serif";
mytree.HoverStyle["color"] = "#000000";
mytree.HoverStyle["font-size"] = "11px";

mytree.SelectedStyle["font-family"] = "Verdana,Arial,Sans-serif";
mytree.SelectedStyle["color"] = "#000000";
mytree.SelectedStyle["font-size"] = "11px";

Paul Schaeflein did a post about an example how to programmatically upload a file to a document library. The example is in VB.NET and could be very handy to use in custom made WebParts. Thanks for that! :)

Sub ProcessPostedFile(ByVal fileUpload As HtmlControls.HtmlInputFile)
    Try
    ' get the filename and stream
    Dim fn As String = System.IO.Path.GetFileName(fileUpload.PostedFile.FileName)
    Dim stm As System.IO.Stream = fileUpload.PostedFile.InputStream
    Dim contents(CInt(stm.Length)) As Byte

    stm.Read(contents, 0, CInt(stm.Length))
    stm.Close()

    ' get the library path
    Dim docLibPath As String = Configuration.ConfigurationSettings.AppSettings("DocUploadPath")
    ' first, get the site containing the library
    Dim site As SPSite = New SPSite(docLibPath)
    Dim web As SPWeb = site.OpenWeb
    ' then get the folder
    Dim docFolder As SPFolder = web.GetFolder(docLibPath)

    ' delete the file if it exists
    Dim docFile As SPFile
    Try
        docFile = docFolder.Files(fn)
    Catch ex As Exception
    End Try

    If Not docFile Is Nothing Then
        docFolder.Files.Delete(fn)
    End If

    ' save the file
    docFile = docFolder.Files.Add(fn, contents)

    Catch ex As Exception
        Context.Trace.Warn(ex.ToString)
    End Try
End Sub

Article written by Bil Simser doing the same upload using a HTTP PUT. Meaning that you could use it from any place and not only on the SharePoint server.

Patrick Tisseghem pointed out to us a nice article by Christophe Lauer which has created a sample application demonstrating the concept of programming against the Desktop Search API. I'm using the Desktop Search myself and find it incredible usefull. You can download the sample application at Christophe Lauer his site.

At the blog of Stramit's SharePoint Blog a great article explains how to create rounded header corners for a WebPart by just using CSS styles. 2 cells and 2 styles are used namely: ms-WPTitle and ms-WPHeader.

One of my collegea pointed out a link to "patterns & practices Enterprise Library - June 2005" containing the following as stated on the website of Microsoft:

"The patterns & practices Enterprise Library is a library of Application Blocks designed to assist developers with common enterprise development challenges. Application Blocks are a type of guidance, provided as source code, that can be used as-is, extended or modified by developers for use on enterprise development projects. The June 2005 release of Enterprise Library is a minor update of the original version released in January 2005. Enterprise Library features new and updated versions of application blocks that were previously available as stand-alone blocks. All blocks included in Enterprise Library have been updated with a particular focus on consistency, extensibility, ease of use and integration."

A must have for every developer :) Thanks Stef!!

Angus Logan has been using AJAX.NET under SharePoint and came accross a "cast exception" when using RegisterTypeForAjax. He explains in his article a solution for this by adding manually the client side references to AJAX.NET.

Rumours says that in the last weeks of july beta 2 will be released. It is worth while waiting for that version to start with :)

 If you use for example a Repeater and you do not want to show some field from the DataSource based on a expression, you could use the following solution. This example hides the year when the year in the DataSource is zero.

<asp:Repeater runat="server" id="rptGroup">
   <HeaderTemplate>
      <table>
   </HeaderTemplate>
   <ItemTemplate>
      <tr><td>
         <asp:Label id="lbl" runat="server" 
            Visible='<%#DisplayYear(DataBinder.Eval(Container.DataItem, "year"))%>'>
            <%#DataBinder.Eval(Container.DataItem, "year")%>
         </asp:Label>
      </td></tr>
   </ItemTemplate>
   <FooterTemplate>
      </table>
   </FooterTemplate>
</asp:Repeater>

In the code-behind the following method is added:

public bool DisplayYear(object item)
{
   int year = 0;

   try
   {
      year = Convert.ToInt32(item);
   }
   catch(exception)
   {
   }

   return year != 0;
}
