Visual InterDev

  • Article

When you lay out a page, you design it so that the user can easily scan the page for content, navigation, and orientation. Microsoft® Visual InterDev™ includes a new feature, layouts, which makes it easy to organize your pages into logical regions.

When a layout is applied to a page, the layout:

  • Defines how the content of the page is visually laid out in regions.

  • Implements navigation among parent, children, and sibling pages using the PageNavbar design-time control.

  • Includes a consistent use of a title region, if desired.

Applying a Layout to a Project

When you create a Web project, you can choose a default layout for the project.

To set a default layout when creating a Web project

  • Run the Web Project wizard and select a layout when prompted.

Now, by default, all pages that you create in the Web project will use the default layout.

You can still use layouts if you choose not to use one when creating the project.

To apply or change the default layout of an existing Web project

  1. In the Project Explorer, select the project name.

  2. From the View menu, choose Property Pages.

  3. In the dialog box, select the Appearance tab.

  4. Under Default Theme and Layout, choose Change to specify a layout.

If you later decide that you don't want to use a layout, you can remove it from the project without affecting the content.

To remove a layout from a Web project

  1. In the Project Explorer, select the project name.

  2. From the View menu, choose Property Pages.

  3. In the dialog box, select the Appearance tab.

  4. Under Default Theme and Layout, choose Change.

  5. Select Apply to activate the scrolling list of layouts.

  6. At the top of the list, select <none>.

At this point, the layout is no longer applied to the project, but the layout files still exist in the project. If you want to actually remove the files from the project, select the unwanted layout in your project's _Layouts folder and delete it.

Applying a Layout to a Single Page

You can apply a layout to a single page. If the project that contains the page already has a default layout, the page-level layout overrides the project default.

To apply or change the layout of a single page

  1. In the Project Explorer, select an .htm or .asp file.

  2. From the Edit menu, choose Apply Theme and Layout.

  3. In the dialog box, select the Layout tab.

  4. Select Apply and specify a layout.

If you later decide that you do not want a layout applied to a particular page, you can choose to apply no layout or return to the project default.

To remove a layout from a single page

  1. In the Project Explorer, select an .htm or .asp file.

  2. From the Edit menu, choose Apply Theme and Layout.

  3. In the dialog box, select the Layout tab.

  4. Select Preserve Current Layout.

    -or-

    Select the Apply option and then <none> from the list.

    Preserve Current Layout instructs Visual InterDev to use the project's default layout, while <none> explicitly specifies that there is no layout applied to the page.

Note   The Apply Theme and Layout command is disabled when you are working offline.

Previewing a Layout

You can browse through the layouts in the Apply Theme and Layout dialog box. Images appear in the dialog box that are representative of the layouts themselves. This preview allows you to see how a layout looks before you apply it to a page or project.

To preview a layout

  1. In the Project Explorer, select an .htm or .asp file.

  2. From the Edit menu, choose Apply Theme and Layout.

  3. In the dialog box, select the Layout tab.

  4. Click on any layout on the left to display a preview on the right.

Creating Custom Layouts

You can create your own custom layout to meet your own design needs. Layouts are located in the _Layouts directory of a project.

Note   If you haven't yet applied a layout to a project or to one of the project files, then the _Layouts folder won't yet exist in your project.

Each Visual InterDev layout is comprised of three files. You can open the files in the editor in order to become more acquainted with their contents. The files serve the following purposes:

File name Purpose
name.inf name is the name of the layout. name matches the name of the parent folder. This file contains information about the layout.
Layout.htm This template contains the HTML that is inserted into a page when a layout is applied to the page.
Preview.htm This file is called when the layout is selected in the Apply Theme and Layout dialog box.

The easiest way to create a custom layout is to copy an existing one and then modify it.

To create a custom layout template

  1. In the project's _Layout folder, create a new folder and name it.

  2. Copy the files from one of the existing layout folders and paste them into you new folder.

  3. In your new folder, select the .inf file and rename it so that it matches the folder name.

  4. Double-click the .inf file to open it.

  5. On the title= line, specify a new title. This is the string that appears in the list of layouts in the Apply Theme and Layout dialog box.

  6. Save and close the .inf file.

  7. Double-click Layout.htm to open it in the editor.

  8. Click the Source tab of the editor. Now you can see the Layout design-time controls and the HTML tags that define the layout's table. Modify the HTML tags and text to suit your needs.

    ****Warning   ****Do not modify the run-time text of the Layout design-time controls.

  9. Save and close Layout.htm.

  10. Double-click Preview.htm to display it in the editor. This file is called when the layout is selected in the Apply Theme and Layout dialog box. Edit the file to suit your needs.

  11. Save and close Preview.htm.

Now Visual InterDev will automatically include your custom layout in the list of available layouts when you display the Apply Theme and Layout dialog box.
