Question

I have one web control (called A) and one web page (Called Default).

Is there a way to call a JavaScript function from Default that belongs to A instead of using OnClientClick?

I am using the following in Page_Load of Default.aspx.cs (This is where my JavaScript function is coming from):

a = (A)LoadControl("~/A.ascx");
a.ID = "AgControl";
panel.Controls.Add(a);

In Default.aspx I have the following:

<asp:Button ID="Button1" runat="server" Text="Button" 
OnClick="Button1_OnClick"
OnClientClick="JavaScript()"  />

DefaultPage.aspx.cs:

protected void Button1_OnClick(object sender, EventArgs e)
   {
  String a = getValueofA();

  If (a == "1")
  {
            //OnClientClick code goes here
  }
  else If (a == "2")
  {
     //No OnClientClick code goes here
  }
 }

My goal is to remove OnClientClick="JavaScript() and code it only in the first part of the “if statement”.

ScriptManager.RegisterStartupScript

Example:

ScriptManager.RegisterStartupScript(
    Page,
    Page.GetType(),
    "uniquescriptkey", 
    "alert('hi');",
    true
);
