[C# WEB] Accessing a dynamically created label in a label array

[karthik25]

Hi,

The following code creates a tab container, 5 tab panels, buttons, labels. I was able to add event handlers to the button. But how am i supposed to access the dynamically created labels? For example how do i get the text of the label changed when the corresponding button is clicked? I have given the complete code below. Please help me with this.

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.IO;
using AjaxControlToolkit;
 
public partial class Wdg : System.Web.UI.Page
{
    protected TabContainer tbCon;
    protected TabPanel[] tbPanel;
    protected UpdatePanel[] updPanel;
    protected Label[] lblMessage;
    protected Button[] btnClick;
 
    protected int count;
    private int i;
 
    protected void Page_Load(object sender, EventArgs e)
    {
        count = 5;
 
        tbCon = new TabContainer();
        tbCon.Width = 600;
 
        tbPanel = new TabPanel[count];
        updPanel = new UpdatePanel[count];
        lblMessage = new Label[count];
        btnClick = new Button[count];
 
        for (i = 0; i < count; i++)
        {
            tbPanel[i] = new TabPanel();
            tbPanel[i].HeaderText = "Tab " + i.ToString();
 
            updPanel[i] = new UpdatePanel();
 
            lblMessage[i] = new Label();
            lblMessage[i].Text = "Label " + i.ToString();
            lblMessage[i].ID = "lblMessage" + i.ToString();
 
            btnClick[i] = new Button();
            btnClick[i].Text = "Button " + i.ToString();
            btnClick[i].ID = "btnClick" + i.ToString();
            btnClick[i].Click += new EventHandler(Wdg_Click);
 
            updPanel[i].ContentTemplateContainer.Controls.Add(lblMessage[i]);
            updPanel[i].ContentTemplateContainer.Controls.Add(btnClick[i]);
 
            tbPanel[i].Controls.Add(updPanel[i]);
 
            tbCon.Controls.Add(tbPanel[i]);
        }
 
        form1.Controls.Add(tbCon);
    }
 
    void Wdg_Click(object sender, EventArgs e)
    {
        Button btn = (Button)sender;
 
        StreamWriter s = new StreamWriter(new FileStream("EventLogger.txt", FileMode.Append));
        s.WriteLine("ID is " + btn.ID.ToString());
        s.WriteLine(btn.ID.ToString()[btn.ID.ToString().Length - 1]);
 
 
    /* How do i modify the contents of the label in this update panel? */
 
        s.Close();
    }
}
 

Thanks
Karthik

I found out the solution, thank god!

Ans:

lblMessage[i - 48].Text = "Clicked"; 

I didn't try this at all!
