How to add dynamic controls with different ID and having a different Click event in asp.net on a button click?
protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)
ViewState["i"] = 1;
protected void Button1_Click(object sender, EventArgs e)
int i = (int)ViewState["i"];
Button MyButton = new Button();
MyButton.ID = "MyButton" + i;
divContainer.Controls.Add(MyButton);
i++;
ViewState["i"] = i;
Whenever i click on button to add a new control in a div with id="descriptionBox", then last created control gets deleted from that div and new control gets created instead.I want to create a new control on every click And add them into that div.

As you are using Asp controls, it renders at server side
every time you add control it refreshes the page and previous content goes away
you can use Page_PreInit event
protected void Page_PreInit(object sender, EventArgs e)
Request.Form.AllKeys.Where(key => key.Contains("button name")).ToList();
event to retain or re-Create the existing control
for more information have a look on the link https://www.aspsnippets.com/Articles/ASPNet-Dynamic-Controls-ViewState-Retain-state-for-dynamically-created-controls-on-PostBack.aspx
