Controls You Can Use on Web Forms ASP.NET IE WebControls MultiPage WebControl
MultiPage controls can be nested, or used within another MultiPage.
This is particularly useful when presenting subsets of pages within the main set of pages. This section briefly explores an example that includes the previous MultiPage sample ( showing thumbnails and full images ), nested within another MultiPage.
The below procedures show the minimum steps needed to display nested MultiPage controls.
- Add the processing directives. See Adding MultiPage Controls to a Web Forms Page.
- On the <body> section of the document structure, declare the <
ie:multipage> elements and optionally set the controls’ base properties.
Nesting MultiPage elements is pretty straightforward, with markup taking the following form.
<ie:multipage id="multipage1" runat="server">
<ie:pageview id="page1">
... page1 content goes here ...
</ie:pageview>
<ie:pageview id="page2">
<ie:multipage id="multipage2" runat="server">
<ie:pageview id="subpageA">
... subpageA content goes here ...
</ie:pageview>
<ie:pageview id="subpageB">
... subpageB content goes here ...
</ie:pageview>
</ie:multipage>
</ie:pageview>
</ie:multipage>
- Next, add the interface to enable the user to navigate the main set of pages.
For this example, we use <asp:button> controls.
<asp:button id="btnBack" runat="server" font-size=9pt
text="< Back" onclick="backClick" />
<asp:button id="btnNext" runat="server" font-size=9pt
text="Next >" onclick="nextClick" />
- Lastly, add code to handle the navigation.
Basically when either of the buttons is clicked in this example, the corresponding handler simply increments or decrements the SelectedIndex property of the MultiPage. 
public void nextClick ( object sender, EventArgs e ) {
if ( cityInfo.SelectedIndex < ( cityInfo.Controls.Count - 1 ) ) {
cityInfo.SelectedIndex ++;
setButtons ( );
}
}
public void backClick ( object sender, EventArgs e ) {
if ( cityInfo.SelectedIndex > 0 ) {
cityInfo.SelectedIndex --;
setButtons ( );
}
}
