hi padma, finally come across the solution for your problem. Good Question. Below code will work perfectly.
////////////////////////Aspx/////////////////////
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:PlaceHolder ID="placeHolder1" runat="server"></asp:PlaceHolder>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</div>
</form>
</body>
</html>
////////////////////////End Aspx/////////////////////
---------------------------C#-----------------
The event will never be fired because your control (and its handler) doesn't exist : you have to create it before the event can be treated.
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
if (DropDownListAdded)
CreateStatus(null);
}
else
DropDownListAdded = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
if (!DropDownListAdded)
{
CreateStatus("Closed");
DropDownListAdded = true;
}
}
private void CreateStatus(string value)
{
Label label = new Label();
label.Text = "Status: ";
placeHolder1.Controls.Add(label);
DropDownList dropdown = new DropDownList();
dropdown.Width = new Unit(108);
dropdown.AutoPostBack = true;
dropdown.SelectedIndexChanged += new EventHandler(statusDropdown_SelectedIndexChanged);
dropdown.ID = "stausDropdown";
dropdown.DataSource = new string[] { "Open", "Closed", "pending" };
dropdown.DataBind();
if (value != null)
dropdown.SelectedValue = value;
placeHolder1.Controls.Add(dropdown);
}
void statusDropdown_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Write(((DropDownList)sender).SelectedValue);
}
private bool DropDownListAdded
{
get { return (bool)ViewState["ddla"]; }
set { ViewState["ddla"] = value; }
}
-----------------------------------End C#--------------------------
