Register the user control in default.aspx as:

XML

<%@ Register TagPrefix="so" TagName="UserControl" Src="~/myUserControl.ascx" %>

Instance of the user control is created as:

XML

<so:UserControl ID="UserControl1" runat="server" Title="Control 1" OnRemoving="UserControl1_Removing" />

In code behind, handle the user control evnt as:

C#

protected void UserControl1_Removing(object sender, EventArgs e)
{
    myUserControl ctrl = (myUserControl)sender;
    ctrl.Visible = false;
}

thanks for the reply, but could you please show me how to build the property for the fieldset in ascx.cs page and in the aspx.cs page change the visibility of the fieldset to false or true. because i could do it for the panel:

Control panelControl31 = WebUserControl31.FindControl("Panel1");
Panel pControl1 = (Panel)panelControl31;
pControl1.Visible = false;

but i couldn't do it for the fieldset inside the panel.
really appreciate.

you can try this. if you have question or problem ask me.

foreach (Control c in UpdatePanel1.Controls)
        {
            if (c.GetType().Name.ToLower() == "uc_ascx")//YOUR USER CONTROL NAME:for exacmple:uc_ascx
            {
                UserControl uc = (UserControl)c;
               
                TextBox txtbox1 = (TextBox)uc.FindControl("Textbox1");//you must CAST type of destination control. for example textbox or button, label , hyper link
                Label label = (Label)uc.FindControl("Labl1");
                Button button = (Button)uc.FindControl("button1");
                // done your job
                string value1 = txtbox1.Text;
                string value2 = label.Text;
                string value3 = button.Text;
            }
        }

in user control put some control like textbox or label
then when you added this user control on Main.aspx in the code behind of Main.aspx, add this function at event(for example: button click event )
then you can get all of the property of control that you like, but you must use of your control instead of :

TextBox txtbox1 = (TextBox)uc.FindControl("Textbox1");

string value1 = txtbox1.Text;

Thank Morteza for reply.
the updatepanel is in aspx page and the labels, textbox and all content is located at the usercontrol page. i have fixed it.
please check out the answer.
but for editing part i have done some thing like what you have mentioned and using itemDataBound function of listview.

protected void lvProduct_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
Label EmpIDLabel = (Label)e.Item.FindControl("EmpIDLabel");
System.Data.DataRowView rowView = e.Item.DataItem as System.Data.DataRowView;
EmpIDLabel.Text = rowView["EmpID"].ToString();
}
}

regards

i have fixed the problem.
i have put one HiddenField variable at my usercontrol page:

<asp:hiddenfield id="hid_choosingField" value="" runat="server" xmlns:asp="#unknown" />

then i have accessed and changed it from aspx.cs page:

Control hidField = WebUserControl31.FindControl("hid_choosingField");
    HiddenField ucHidField = (HiddenField)hidField;
    ucHidField.Value = "1";

then i have put a if condition at the ascx page to check what is the HiddenField value and base on the value i show the related fieldset:

<% if (hid_choosingField.Value == "1")
   { 
%>
    <fieldset id="uc3Fieldset1" style=" height:350px;">
    <legend>New Module Details</legend>

        <asp:label id="Label2" runat="server" forecolor="blue" text="This is User Control 3 Panel 1 Fieldset 1" />
    </fieldset>

   }
   else if (hid_choosingField.Value == "2")
   { 

    <fieldset style=" height:350px;">
    <legend>New Module Details</legend>

        <asp:label id="Label1" runat="server" forecolor="blue" text="This is User Control 3 Panel 1 Fieldset 2" />
</fieldset>

i hope it would be helpful. thanks
