I don't have a sample code for this for now. You can try this:

1. Create a user control with a tablelayoutpanel in it.
2. Add a method to it that takes in one integer parameter. In that method, add rows and columns to the panel and add buttons in it.
3. Search for "delegates and events" or "c# expose events from user control" to understand how to expose the click event for the buttons and handle it in the creating form.

Do like this :

Button newButton = new Button();
newButton.Location = new Point(30,50); // Put your calculated point here.
newButton.Text = "Click Me";
newButton.Size=new Size(50,25);
newButton.Click += new EventHandler(newButton_Click);
this.Controls.Add(newButton);

Place your Eventhandler as newButton_Click.

public void newButton_Click(object sender, EventArgs e)
{
 // Do all you need.
}

Please do post in right forum next time... D'Oh! | :doh:

0) You're using Visual Basic.

1) You're not "splitting" the string, you're extracting part of it.

2) You're converting "000234" to an integer. The integer will be equal to 234. If you want to maintain the leading zeros, you have to leave it as (or convert it back to) a string.

3) I've noticed this leading-zeros on an integer question pop up several times this week. Will you guys please tell your instructors to give you the low-down on this particular topic BEFORE giving you your homework assignment.

There are various ways to do it.If your users are in the domain then you can deploy your web service with windows authentication.Another way when some one access to your web service method ask credential as a parameter then authenticate the request and return the result as appropriate.Also
Have a look

Try this:

Take 2 update panels.

Put all user details related controls in one update panel and password related controls in second one.

In this way, when you select an item from drop down list only the first update panel will refresh.

First check the scope of the methods you want to access by creating the object.

And if every thing seems to be fine then post some relevant code of the class and how you are trying to access the methods.
