Thanks for reply. Um, lbl1 is not dynamic. It's created in the non-code file:
<asp:Label id="lbl1" text="No text yet" runat="server" />Ok here goes. Why I'm creating a button inside a dynamically created table is beyond scope, but that's the context. Here's the code portion:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
public void MakeTable(object sender, EventArgs e)
{
HtmlTableRow rownp = new HtmlTableRow();
HtmlTableCell cellnp = new HtmlTableCell();
//THE DYNAMIC BUTTON IS HERE **************************************
Button bt = new Button();
bt.Text = "Click Me";
bt.Click += new EventHandler(bt_Click);
cellnp.Controls.Add(bt);
rownp.Controls.Add(cellnp);
TheTable.Rows.Add(rownp);
}
protected void Page_Load(object sender, EventArgs e)
{
}
void bt_Click(object sender, EventArgs e)
{
lbl1.Text = "Hello";
}
}<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:Button ID="btMakeTable" Text="Make Table" OnClick="MakeTable" runat="server" />
<asp:Label ID="lbl1" Text="No text yet" runat="server" />
<table id="TheTable" border="0" cellpadding="0" cellspacing="0" runat="server" />
</asp:Content>TheTable is a static element to which rows and cells are added dynamically:
.
.
<table id="TheTable" border="0" cellpadding="0" cellspacing="0" runat="server" />
.
.Ok. Bind it to what? (sorry never b4 made dynamicly created controls before) Constructing the table works and displays everything including the buttons (no compilation errors). But without binding it, controls within it cannot trigger events?
No. It's just testing the idea. I will have a table that may need dynamically created buttons in the rows triggering an event.
Yeah I know that. I want the text to change inside the event handler of the dynamically created button to show that it's event is triggering.
public void MakeTable(object sender, EventArgs e)
{
TableRow rownp = new TableRow();
TableCell cellnp = new TableCell();
Button bt = new Button();
bt.Text = "Click Me";
bt.Click += new EventHandler(bt_Click);
cellnp.Controls.Add(bt);
rownp.Controls.Add(cellnp);
TheTable.Rows.Add(rownp);
TheTable.DataBind(); //**********************
}
void bt_Click(object sender, EventArgs e)
{
lbl1.Text = "Hello";
lbl1.DataBind(); //**********************
}The viewstate should be retained by default.trying to do MVC and this at the same time is not helping
I personally think that when its posting back its losing the controls in the viewstate.
Stelly
HtmlTableRow rownp = new HtmlTableRow();
HtmlTableCell cellnp = new HtmlTableCell();
Button bt = new Button();
bt.Text = "Click Me";
bt.Click += new EventHandler(bt_Click);
cellnp.Controls.Add(bt);
rownp.Controls.Add(cellnp);
TheTable.Rows.Add(rownp);<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
Is not DataBind() related to the DataSource property tho? So by itself it does nothing, no?Same time?!
DataBinding controls registers them in the view state. The ASP life cycle is annoying as hell, and you need to databind your controls for every cycle - thus my suggestion to try binding the label in the event
rb.DataSource=myList;
rb.DataBind();Yeah the "BodyContent" object is a place holder. I've seen an example of adding content to a place holder ... was trying to find it just now. But I think the statically declared <table ... runat="server" /> is essentially a place holder too is it not?
I just tried adding the button to the following place holder (which itself worked), but the event still didn't trigger.
<asp:PlaceHolder ID="h" runat="server"></asp:PlaceHolder><asp:Label ID="lbl1" EnableViewState="true" Text="No text yet" runat="server" /><asp:Button ID="btStatic" Text="Static" OnClick="bt_Click" runat="server" />Thanks for help. The "whole code" regarding this is literally just the brief test code in order to see if it will work. I have not incorporated this into any project yet.
