calling two functions on asp.net button onclick

Question

I want to call two functions on button click I tried like this

 <asp:Button ID="Button2" runat="server" Font-Bold="False" onclick="tableShow();Unnamed1_Click" Text="Search" 
         Width="63px">

Answer 1

you can use the method inside method to do this. First do this

<asp:Button ID="Button2" runat="server" Font-Bold="False" onclick="Unnamed1_Click" Text="Search" 
         Width="63px">

then in code behind

protected void Unnamed1_Click(object sender, EventArgs e)
{
    //call another function here
}

Answer 2

OnClick is a server side event. Hence you can assign one method and from that method make a call to other method as below.

In asp markup

<asp:Button ID="Button2" runat="server" Font-Bold="False" onclick="Unnamed1_Click" 
 Text="Search" Width="63px">

In code behind

protected void Unnamed1_Click(object sender, EventArgs e)
{
    this.tableShow();
    //Do your actual code here.
}

UPDATE

If tableShow is a javascript method then you can use the below markup

<asp:Button ID="Button2" runat="server" Font-Bold="False" 
 OnClientClick="tableShow();" onclick="Unnamed1_Click" Text="Search"
 Width="63px">
