You can use session variable to store your visibility flag for your next page control.

Use Query string in first page and check in second page if query string having value then disabled the controls.

Hi,

you can make use of query string. try like below.

First Page.

C#

protected void btn_view_Click(object sender, EventArgs e)
{
    string str = "";
    Session["btn_view"] = str;
    Response.Redirect("secondpage.aspx?Type=view");       
}
protected void btn_update_Click(object sender, EventArgs e)
{  
    Session["update"]=str_d ;
    Response.Redirect("secondpage.aspx?Type=upd");
}

Second Page.

C#

protected void Page_Load(object sender, EventArgs e)
{
    if(Request.QueryString["Type"].ToString() == "view")
    {
        btn_Update.Visible = false;
        btn_Delete.Visible = true;
    }
    else if(Request.QueryString["Type"].ToString() == "upd")
    {
        btn_Update.Visible = true;
    }    
}

refer Passing variables between pages using QueryString[^] for more on query string.

hope it helps.
