How about using a hyperlink (a tag of html) such like:

<a href="xxx.aspx"
  onclick="window.open(this.href, ...); return false;">
  Open xxx.aspx
  </a>

Please set 2nd and 3rd arguments at ... in window.open(this.href, ...) as required according to the MDN Document Window: open() method.

Hi @Simon,

open a page (a from) from within an open page

I think you might be looking for something like Bootstrap Modal, where you can add some form controls (eg: TextBox) inside the modal (modal-body).

Simple code below:

<head runat="server">
    <title>Modal Test</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/css/bootstrap.min.css" rel="stylesheet" />
    <script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
    <script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.1/dist/umd/popper.min.js" integrity="sha384-9/reFTGAW83EW2RDu2S0VKaIzap3H66lZH81PoYlFhbGU+6BZp6G7niu735Sk7lN" crossorigin="anonymous"></script>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/js/bootstrap.min.js" integrity="sha384-+sLIOodYLS7CIrQpBjl+C7nPvqq+FbNUBDunl/OZv93DB7Ln/533i8e/mZXLi/P+" crossorigin="anonymous"></script>
</head>
<body>

    <form id="form1" runat="server">

        <!-- Button trigger modal -->
        <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalCenter">
            Launch demo modal
        </button>

        <!-- Modal -->
        <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true" data-backdrop="static" data-keyboard="false">
            <div class="modal-dialog modal-dialog-centered" role="document">
                <div class="modal-content">
                    <div class="modal-header">
                        <h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                            <span aria-hidden="true">&times;</span>
                        </button>
                    </div>
                    <div class="modal-body">
                        Box1: 
                        <asp:TextBox runat="server" ID="Name" />
                        <br />
                        Box2:
                        <asp:TextBox runat="server" ID="PWD" />
                    </div>
                    <div class="modal-footer">
                        <button type="submit" class="btn btn-primary">Save</button>
                    </div>
                </div>
            </div>
        </div>
    </form>
</body>

If you want to implement this with some existing controls, you can also see if ModalPopupExtender is suitable for you.

you need to make your requirements clearer. server code can not open a page, only return a response.

to open a page in a new window/tab you use an anchor.

<a href="~/newpage.asps" target="_blank">click me</a>

you can use javascript (rendered by the server) to automate:

<a style="display:none" id="openPage" href="~/newpage.asps" target="_blank">click me</a>
<script>document.getElementById("openPage").click();<script>

Answer 4

In a sense, you don't really "open some page", but in fact navigate to a given page.

So, say we have a button on FormA.aspx, and we want to open (well, better stated navigate to) FormB.aspx?

Then our button would be this:

            <asp:Button ID="cmdOpenA" runat="server" Text="Open Page B"
                OnClick="cmdOpenA_Click"
                />

So, the above would be our button in FormA.aspx. The code behind, to jump to FormB.aspx then could be this:

    Protected Sub cmdOpenA_Click(sender As Object, e As EventArgs)

        Response.Redirect("FormB.aspx")

    End Sub

Now, often, one might include the full path name in the code, so above thus might be:

        Response.Redirect("~/Testing/FormB.aspx")

So, above would be from the root (start of base site), and then in a folder called Testing, we open the formB.aspx).

This of course would thus "navigate" to the new page. So, the term "open a page" probably not the best terminology here. Now, perhaps when you click the button, we want to open another browser tab? Again, not a great UI, and think of say when you use this site to ask your question? You click buttons, navigate around - but we not really "opening" new browser tabs, are we?

So, in web land, the idea of "opening" a page is better stated that we are to click on a button, and "navigate" to another page.

And that button could even be say inside of a simple Gridview. Say this markup:

    <asp:GridView ID="GHotels" runat="server" AutoGenerateColumns="False" 
        DataKeyNames="ID" CssClass="table table-hover"
        width="40%">
        <Columns>
            <asp:BoundField DataField="FirstName" HeaderText="FirstName"  />
            <asp:BoundField DataField="LastName" HeaderText="LastName"    />
            <asp:BoundField DataField="HotelName" HeaderText="HotelName"  />
            <asp:BoundField DataField="Description" HeaderText="Description"  />
            <asp:TemplateField HeaderText="Edit">
                <ItemTemplate>
                    <asp:Button ID="cmdEdit" runat="server" 
                        Text="Edit" CssClass="btn" 
                        OnClick="cmdEdit_Click" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

So, in above, we have a standard button. (to edit the row of data).

So, clicking the button, then we have this effect:

editonehot

And the code behind that button?

this:

    Protected Sub cmdEdit_Click(sender As Object, e As EventArgs)

        Dim btn As Button = sender
        Dim gRow As GridViewRow = btn.NamingContainer
        Dim intPK As Integer = GHotels.DataKeys(gRow.DataItemIndex)("ID")

        Session("PK") = intPK
        Response.Redirect("EditOneHotel.aspx")

    End Sub

So, once again, note how we really don't "open" a new form, but better stated is we navigate to that form. The above button code thus gets the current row PK of the database. We then navigate to the 2nd page which displays the hotel, allowing one to edit, or cancel.

Now, we could for example pop up, or pop open a dialog in place of navigating to the new/difference .aspx page. I tend to prefer this approach, and then the above would look like this:

popeditnew2

So, in web land, as opposed to desktop land, the term "open" a page requires more explain on your part. Since it not clear if you want:

To jump/navigate to a new page when clicking a button.

Pop open a dialog of some type?

Open a new tab in the browser?

You have lots of choices here, but the general idea is that when you click on a button, you can most certainly "jump" or navigate to a difference page, and I suppose could say we are "opening" that new page, but we are in near call cases actually navigating to that new page.

So for button click code? You just use Response.Redirect("page to jump here")

Ok, this suggests we need more information. First up, what kind of project did you create here? The above answer is of course in terms of what we call a WebForms project, and it rather possible that you created a different type of web site. (there are MANY choices for what type of web project you create, and thus what syntax and how you jump/navigate to another page will matter. For starting out, then I suggest you create a new Asp.net web forms application. That is this choice when creating a new project.:

So, there are "many" types of web projects, and this is just a natural progression of technology over the years. If you create a MVC project, then in code behind you not be using response.Redirect("some url"), since such projects work rather different. So, the type of web technology and project you create matters here. I would suggest you try creating the above "web forms" project. So, after you select the above template, then the next screen of choices are:

Then next, and we have this choice:

I would also on the right side un-check the configure for https - you really don't need that setting as of yet.

So, try creating the above web forms project - it will create a whole site with a working menu bar etc. As such, then when adding new .aspx pages to the project? Then the suggested syntax of using Response.Redirect("some url") should work fine for you.

So, we need to know what kind of project you created, since different project types will have different coding approaches here.
