C# .NET - tab ctrl btn cliked

i m using tabcontol.. which has 4 tab page.. and i want that when user click on first tab then msg box should be shown first tab clicked and when clicks second then should be shown second tab clikced... i dont know on which event i have to write code.. i want to write code seprately for each tab page when button clicked.

Use TagbControl selected changed event instead, or you can also recognize the Enter event when the tab page is clicked in show the message box:
User Control:

namespace TestPropogateTabEvent

{

public partial class UserControlWithTab : UserControl

{

public UserControlWithTab()

{

InitializeComponent();

}

public delegate void TabSelectionEventHandler(object sender, EventArgs e);

public event TabSelectionEventHandler PropogateSelectionChange;

private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
 {

  if (PropogateSelectionChange != null)
  {
   PropogateSelectionChange(sender, e);
  }

}

}

}

Form Class:

namespace TestPropogateTabEvent

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

userControlWithTab1.PropogateSelectionChange += new UserControlWithTab.TabSelectionEventHandler(userControlWithTab1_PropogateSelectionChange);

}

void userControlWithTab1_PropogateSelectionChange(object sender, EventArgs e)

{

MessageBox.Show("Tab In User Control Pressed");

}

}

}
 


Thanks

Simply implement the SelectedIndexChanged event of tab

private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
  MessageBox.Show("you are at " + tabControl1.SelectedTab.ToString() + " Tab");
 
}
