This question makes no difference. Create a event hander for checkbox and set AutoPostBack property of checkbox to true in your TreeView(Checkbox should be there in your ItemTemplate of TreeView).
Try this:
HTML

ASP.NET

<asp:checkbox id="chk" runat="server" text="test" autopostback="true" oncheckedchanged="chk_CheckedChanged" />

C#:

C#

protected void chk_CheckedChanged(object sender, EventArgs e)
{
    //Write your code or call a function here.
}
