What is the use of delegate


I have studied lots of books and materials on internet but I can never understand what is the use of delegate in development. Actually I want to know in what particular situation a developer should use delegate in code. Please provide me some example.

How Do I maintain the chronological order in which Asynchronous delegate calls are made?


I have created a basic logging framework for my application that writes log messages to a local text file using an Asynchronous delegate.

My application has many threads running however, and as a result, the order of the log entries in the text file is not chronological.

So I have two competing requirements: on one hand, my WriteToLog() method has to return almost immediately so that it doesn't block in-flight code, while at the same time the log file has to be in chronological order.

Any ideas?  Some of the problems I've encountered are:

1a.  Trying to use a Queue (with a lock{ } around it) to maintain the order seems to result in deadlocks

1b.  Even if I use a Queue, at some point the Queue must be written to disk, so it seems like I'd have to frequently have WriteToLog spin off a "WriteToDisk" like method.

2a.  I've considered instantiating a new thread which polls the Queue from (1a) and writes to disk in a loop, say, every 5 seconds.  I'm leaning more towards this method.

3.  I've looked into log4net and some other stuff but it just seems like overkill, and I'd really like to have my own framework for this seemingly simple task.



Delegate issue


Got a user control that has a Listbox on it and I want to be able to pass the selected value back to the main page. 

User Control code:

using System;
using System.Web.UI;

public delegate void SendData(string data);

public partial class _controls_Filter_Staff : UserControl{
    public event SendData mSendData;

    protected void Page_Load(object sender, EventArgs e){

    protected void selStaffList_OnSelectedIndexChanged(object sender, EventArgs e){
        if (Convert.ToInt32(selStaffList.SelectedValue) >= 0 && mSendData != null){

Main page that has the user control:

    protected void Page_Load(object sender, EventArgs e){

        ucFilterStaff.mSendData += GetSelectedStaff; /* ERROR HERE Line 11 */


    private void GetSelectedStaff(string value){
        TextBox txtUserList = (TextBox) fvMain.FindControl("txtUserList");
        if (txtUserList == null) return;

        txtUserList.Text += value + ";";

This is the error I get back and I've tried everything I know, but cannot sort it.  Probably something stupid but I just cannot see it.

SPSecurity.RunWithElevatedPrivileges(delegate(myCode){}); to add file to documentlibrary


I got a document library on which BreakRoleInheritance(false) was executed. I got a test-user which is allowed to view but not add or edit items. Nobody has rights to add an item. But now I got some custom code executed by the test-user which should allow him to add a new file to a documentlibrary.

SPFile newFile;

                        newFile = docLib.RootFolder.Files.Add(
                          fileUrl, fileStream);
Even with elevated privileges the user gets in this line of code a "access denied" message. I'm guessing I'm trying to use the wrong approach so any help is appreciated.

Delegate Control not working


I have a question about delegate controls. I am trying to replace the search box. I have done the following - 

  1. Created a empty SP 2010 project with a control class. 
  2. Added a feature and elements.xml to the same project
  3. Deployed the feature and activated it (I can see it in my site list of features)
But my search box still appears to be the default one...what am I doing wrong?

My elements.xml is as follows - 
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    ControlAssembly="DelegateControl001Feature, Version=, Culture=neutral, PublicKeyToken=69948fee36b953cf"/>

And my ascx file just has a asp:TextBox with custom text in it.

I am assuming that no master file changes are necessary right?

C# delegate Exception


  I am stuck with an InvalidCast Exception. I am calling a delegate to run some function. In the callback method of the delegate I am trying to get the return value of the function as shown below.

         public delegate SyncHelper.SyncPlan RunJobDelegate();

         public static void SyncJobCallback(IAsyncResult result)

            RunJobDelegate runSyncJob = (RunJobDelegate)result.AsyncState;
            SyncHelper.SyncPlan obj_Plan = runSyncJob.EndInvoke(result);

When RunJobDelegate runSyncJob = (RunJobDelegate)result.AsyncState; is called I am hitting an exception saying "Unable to cast object of type 'RunJobDelegate' to type 'RunJobDelegate'. "

System.InvalidCastException was unhandled
  Message=Unable to cast object of type 'RunJobDelegate' to type 'RunJobDelegate'.

SharePoint Search Delegate Control


Any ideas why the search delegate control <SharePoint:DelegateControl runat="server" ControlId="SmallSearchInputBox"/> would not render anything on my portal? Actually, when I looked at the page source, I saw that delegate control did infact render the html however it was enclosed in <div id="SearchArea" style="display:none"></div> so it is hidden.

Thanks for your help

Get delegate arguments inside delegate


Hi all,

Could someone please help me to understand how to get all parameters passed to delegate inside delegate itself?

I have class :

    public class ShopManager : ShopEntities
            public ShopManager getWhere(Func<Object, Object> dataList)
                var x = dataList.???; // how to get arguments?
                return this;
            public Object getLike(Object dataValue)
                return dataValue;

Then i call it as :

    ShopManager shopManager = new ShopManager()
    var demo = shopManager.getWhere(xxx => shopManager.getLike("DATA"));

The question is : **how to get passed parameters "xxx" and "DATA" inside method getWhere()?**

Thanks in advance.
