Why is my asp:Button posting back every other time?
I have a user control that has only a text box and a button. When I click the button the page posts back but the button does not appear in the AllKeys attribute of Request.Form. Once the page loads, if I click the button again it does appear in the AllKeys attribute.
On the next attempt, the third click will not have the button, but the fourth click will have it.
I don't know what I am missing or how to approach this. Why would my asp:Button only post back one every other click?
Control Code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SearchControl.ascx.cs" Inherits="controls.SearchControl" %>
<table style="margin: 0 auto">
<tr>
<td style="vertical-align:middle">
<b>Search ID</b>
<asp:TextBox ID="txtSearchID" AutoPostBack="true" runat="server" Width="100px"></asp:TextBox>
<asp:Button ID='btnLoadDetails' OnClick="Search" runat="server" Text='Load Details' />
</td>
</tr>
</table>
Control Code Behind:
public event EventHandler onLoad;
protected virtual void OnLoad(EventArgs e)
{
if (onLoad != null)
{
onLoad(this, e);
}
}
protected void Page_Load(object sender, EventArgs e)
{
if ( !IsPostBack )
{
if ( Request["searchID"] != null && Conversion.StringToInt( Request["searchID"].ToString() ) > 0 )
{
txtSearchID.Text = Request["searchID"].ToString();
}
}
else
{ // Used to see if teh button appears in Request.Form
String test = Request.Form[btnLoadDetails.ClientID];
}
}
protected void Search(object sender, System.EventArgs e)
{
if (txtShopperID.Text.Trim().Length > 0)
{
OnLoad(new EventArgs());
}
}
Page Code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SearchPage.aspx.cs" Inherits="SearchPage" %>
<%@ Register TagPrefix="search" TagName="searchControl" Src="controls/SearchControl.ascx" %>
<search:searchControl id="searchControl" OnLoad="btnSearch_Click" runat="server" />
