Answer 1

I'm unsure if there is a way to trigger that in asp. But i think JQuery can do that for you.
However a neater way to do it as stated by #Luaan is calling the click event and handle it in the cs code. This way it promotes reuse of codes and no update/change of codes problems.
asp page:
<asp:Button ID="FirstButton" CssClass="BUTT" runat="server" OnClick="onclick="button1_Click" Text="SUBMIT" />
<asp:Button ID="SecondButton" CssClass="BUTT" runat="server" OnClick="onclick="button2_Click" Text="SUBMIT" />
Here in the cs code you handle the event.
I think you want this :
private void button1_Click(object sender, EventArgs e)
{
button2_Click(sender, e);
}
However a neater way would be this:
private void button1_Click(object sender, EventArgs e)
{
InsertIntoDatabase();
}
private void button2_Click(object sender, EventArgs e)
{
InsertIntoDatabase();
}
private void InsertIntoDatabase()
{
// Your Insert into Database codes here
}
So any adjustment to your insert query can be in the method InsertIntoDatabase().
