hello,

I think I know what you looking for. Try the following example. I have 4 buttons on the page and assign the click event to it dynamically.

.aspx page

 
   
   
   
   

.aspx.cs page

 protected void Page_Load(object sender, EventArgs e)
        {
            Btn_Assign_Event();
        }

        void Btn_Assign_Event()
        {
            for (int i = 1; i < 5; i++)
            {
                Button myAllButtons = new Button();
                myAllButtons = Page.FindControl("Button" + i.ToString()) as Button;
                myAllButtons.Click += new EventHandler(myAllButtons_Click);

            }
        }

        void myAllButtons_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            Label2.Text = "you clicked on " + clickedButton.ID;
        }

if you are using MasterPage. use this method

 void Btn_Assign_Event()
        {
            ContentPlaceHolder mpContentPlaceHolder;
            mpContentPlaceHolder = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
            if (mpContentPlaceHolder != null)
            {

                for (int i = 1; i < 5; i++)
                {
                    Button myAllButtons = new Button();
                    myAllButtons = mpContentPlaceHolder.FindControl("Button" + i.ToString()) as Button;
                    myAllButtons.Click += new EventHandler(myAllButtons_Click);

                }
            }
        }

Maik,
Explain your thread with proper information so that we can help you.
Both your posts are different.

I did that with buttons as well and there it was working. I had to deal with 50 Buttons. The Button names are mybutton1 upto mybutton50.
In order to make the code shorter an not to create a separate Click event I decided to concatonate this values:

here some vb.net code: dim myvalue as string = grpTable.Controls("mybutton" + "1").Tag
after this I had the TAG from button "mybutton1" stored in variable myvalue.
