在MOSS開發中,每個朋友都能夠很自然的想到WebPart,的確,在當今的web開發中,為了滿足更多使用者的需求,個人化定製成為了開發人員的一個大難題,不過現在大家似乎不用在為這個問題犯困了,實際上微軟已經幫我們解決了,那就是開發WebPart,但是由於很多朋友不知道WebPart的工作機制,使得開發起來難度較大,現在筆者就介紹一種簡單的WebPart開發方式------使用QuickPart;那麼QuickPart是什麼東西呢?讓我來告訴您,QuickPart就是一種可以將ASP.NET裡頭的WebUserControl打包成標準的SharePoint WebPart,下面筆者通過一些例子介紹如何如何使用QuickPart進行WebPart的快速開發.
此例子要實現的效果是將文件庫的目錄結構綁定至TreeView控制項,採用物件模型(Object Model)編程
筆者建立的是ASP.NET Web應用程式,使用的語言是Visual C#,您可根據自己擅長的程式設計語言建立ASP.NET網站或者ASP.NET Web應用程式,這都是可以的
在編碼之前,筆者先配置環境,使得每次一產生項目,就能夠自動的把我們要的.dll和.ascx拷貝到對應的SharePoint網站目錄的BIN檔案夾和WPRESOURCES下,右擊項目名稱,選擇屬性,在跳出的頁面上選擇”建置事件”,編輯其產生後的命令列
中命令的意思是將產生的.dll檔案拷貝至SharePoint網站所在的目錄” C:\Inetpub\wwwroot\wss\VirtualDirectories\80\bin”下,將專案檔夾下的所有使用者控制項拷貝至” C:\Inetpub\wwwroot\wss\VirtualDirectories\80\wpresources”目錄下,當然,您如果不想配置該命令列,每次產生項目後也可手動拷貝,單擊確定
您可以將項目下的Default.aspx刪除,添加一個Web使用者控制項,筆者取名為TreeCatalog.ascx,往頁面上拖拽一個TreeView控制項,ID設為tvTreeCatalog,筆者建議使用有意義的ID號
由於需要使用到SharePoint命名空間,所以筆者這裡將Microsoft.SharePoint.dll引用至項目中,該.dll所在目錄為” C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI”
TeeCatalog.ascx.cs代碼如下:
Code
Using Microsoft.SharePoint;
Using Micorosft.SharePoint.WebControls;
protected void Page_Load(object sender, EventArgs e)
{
//Page Init
if (!IsPostBack)
{
//calling the method
BindDocLibrary();
}
}
//main method,bind the document library
private void BindDocLibrary()
{
//get the current web content,include list,listitem,folder and so on
SPWeb spWeb = SPContext.Current.Web;
//attention please!your document library must called "我的文件"
SPList spList = spWeb.Lists["我的文件"];
//add the node into treeview by calling the method
tvTreeCatalog.Nodes.Add(CreateNodeByList(spList));
}
private TreeNode CreateNodeByList(SPList spList)
{
TreeNode node = new TreeNode();
//this node is a root node,also is the root node of document library
node.Text = spList.Title;
//get the root folder url of document library
node.Value = spList.RootFolder.Url;
foreach (SPFolder subFolder in spList.RootFolder.SubFolders)
{
//sharepoint site hava a default folder named "Forms",we don't need it
if (subFolder.Name != "Forms")
{
//add the node into treeview by calling the method
node.ChildNodes.Add(CreateNodeByFolder(subFolder));
}
}
return node;
}
private TreeNode CreateNodeByFolder(SPFolder spFolder)
{
TreeNode node = new TreeNode();
node.Text = spFolder.Name;
node.Value = spFolder.Url;
//appoint the node imageurl
node.ImageUrl = SPControl.GetContextWeb(Context).Url + "/_layouts/images/folder.gif";
foreach (SPFolder subFolder in spFolder.SubFolders)
{
//here is uses a recursive process! remark:recursive 遞迴
node.ChildNodes.Add(CreateNodeByFolder(subFolder));
}
return node;
}
Using Microsoft.SharePoint;
Using Micorosft.SharePoint.WebControls;
protected void Page_Load(object sender, EventArgs e)
{
//Page Init
if (!IsPostBack)
{
//calling the method
BindDocLibrary();
}
}
//main method,bind the document library
private void BindDocLibrary()
{
//get the current web content,include list,listitem,folder and so on
SPWeb spWeb = SPContext.Current.Web;
//attention please!your document library must called "我的文件"
SPList spList = spWeb.Lists["我的文件"];
//add the node into treeview by calling the method
tvTreeCatalog.Nodes.Add(CreateNodeByList(spList));
}
private TreeNode CreateNodeByList(SPList spList)
{
TreeNode node = new TreeNode();
//this node is a root node,also is the root node of document library
node.Text = spList.Title;
//get the root folder url of document library
node.Value = spList.RootFolder.Url;
foreach (SPFolder subFolder in spList.RootFolder.SubFolders)
{
//sharepoint site hava a default folder named "Forms",we don't need it
if (subFolder.Name != "Forms")
{
//add the node into treeview by calling the method
node.ChildNodes.Add(CreateNodeByFolder(subFolder));
}
}
return node;
}
private TreeNode CreateNodeByFolder(SPFolder spFolder)
{
TreeNode node = new TreeNode();
node.Text = spFolder.Name;
node.Value = spFolder.Url;
//appoint the node imageurl
node.ImageUrl = SPControl.GetContextWeb(Context).Url + "/_layouts/images/folder.gif";
foreach (SPFolder subFolder in spFolder.SubFolders)
{
//here is uses a recursive process! remark:recursive 遞迴
node.ChildNodes.Add(CreateNodeByFolder(subFolder));
}
return node;
}
以上四個方法就是本例子的代碼,由於頁面較長,筆者就不了,注釋也都寫上,核心的思想就是使用遞迴演算法,請注意,當您直接使用筆者的代碼時請確保您的sharepoint網站下存在名為”我的文件”的文件庫
產生項目,可以在輸出框中看到已經自動將.dll和.ascx檔案複製到sharepoint網站的bin和wpresources目錄下
開啟sharepoint網站首頁,進入”文檔中心”子網站,依次選擇”網站操作”->”編輯網頁”
在左欄地區單擊”添加Web組件”
找到QuickPart,二者選一個即可,單擊添加按鈕
此時頁面仍然處於編輯狀態,並且在左欄的WebPart地區成功添加了ProviderQuickPart組件,下面我們編輯它
選擇”編輯”->”修改共用Web組件”
在頁面右邊彈出的SideBar上就可以看到我們產生的使用者控制項TreeCatalog了,選擇它並單擊確定按鈕
選擇”退出編輯模式”
當您重新開啟sharepoint網站時就可以看到將名為”我的文件”的文件庫成功綁定到TreeView控制項上了.
