ModalDialog

in namespace DotVVM.BusinessPack.Controls

Renders a modal dialog window inside a page.

Usage & Scenarios

Creates a div element styled as a modal dialog that can be shown or hidden any time.

When the dialog is displayed, the content behind it is covered by a semi-transparent backdrop and thus cannot be interacted with.

The Business Pack includes also the Window which can display a similar window but keeps the content behind unlocked.

Sample 1: Basic Usage

The content inside the <bp:ModalDialog> element is treated as a ContentTemplate property which specifies the main content of the dialog.

The IsDisplayed property is bound to the bool property in the viewmodel which controls whether the dialog is shown or hidden. When the user hides the dialog, the property is set to false automatically.

page.dothtml
ViewModel.cs

<bp:ModalDialog IsDisplayed="{value: IsModalDisplayed}">
    <p>Hello!</p>
</bp:ModalDialog>
<bp:Button Text="Show Modal Dialog"
           Click="{command: IsModalDisplayed = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsModalDisplayed { get; set; }
    }
}

Sample 2: Header And Footer

The HeaderText can be used to specify the text in the dialog header. Alternatively, you can use the HeaderTemplate property to be able to use rich HTML content inside the dialog header.

The same applies to the FooterText and FooterTemplate properties which can be used to customize the dialog footer row.

page.dothtml
ViewModel.cs

<%-- Custom content with header and footer text --%>
<bp:ModalDialog HeaderText="This is header"
                FooterText="This is footer."
                IsDisplayed="{value: IsModal1Displayed}">
    <p>Display modal dialog content here.</p>
</bp:ModalDialog>
<bp:Button Text="Show Modal Dialog"
           Click="{command: IsModal1Displayed = true}" />

<%-- Custom content with header and footer template --%>
<bp:ModalDialog IsDisplayed="{value: IsModal2Displayed}">
    <HeaderTemplate>
        <h3>This is header</h3>
    </HeaderTemplate>
    <ContentTemplate>
        <p>Display modal dialog content here.</p>
    </ContentTemplate>
    <FooterTemplate>
        <i>This is footer.</i>
    </FooterTemplate>
</bp:ModalDialog>
<bp:Button Text="Show templated Modal Dialog"
           Click="{command: IsModal2Displayed = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsModal1Displayed { get; set; }
        public bool IsModal2Displayed { get; set; }
    }
}

Sample 3: Closing Dialog

By default, the dialog can be closed when the user clicks outside it.

The CloseOnOutsideClick can be used to disable this behavior. If it is set to false, the dialog will stay open when the user clicks anywhere outside it.

page.dothtml
ViewModel.cs

<bp:ModalDialog IsDisplayed="{value: IsModalDisplayed}"
                CloseOnOutsideClick="false">
    <p>Now you cannot click outside of the dialog to close it.</p>
</bp:ModalDialog>
<bp:Button Text="Show Modal"
           Click="{command: IsModalDisplayed = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsModalDisplayed { get; set; }
    }
}

Sample 4: Dialog Size

The Width and Height properties can be used to specify fixed dimensions of the dialog. You can use any CSS units here - e.g. 400px, 50% etc.

To let the user resize the dialog, set the AllowResize property to true.

The MinWidth and MinHeight properties can restrict the minimum dimensions of the dialog. They are always in pixels.

page.dothtml
ViewModel.cs

<bp:ModalDialog IsDisplayed="{value: IsCustomSizeModalVisible}"
                Width="800px"
                Height="300px">
    <p>I have custom size.</p>
</bp:ModalDialog>
<bp:Button Text="Show Modal Dialog with custom size"
           Click="{command: IsCustomSizeModalVisible = true}" />

<bp:ModalDialog IsDisplayed="{value: IsResizableModalVisible}"
                AllowResize="true"
                MinWidth="200"
                MinHeight="100">
    <p>I can be resized.</p>
</bp:ModalDialog>
<bp:Button Text="Show resizable Modal Dialog"
           Click="{command: IsResizableModalVisible = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsCustomSizeModalVisible { get; set; }
        public bool IsResizableModalVisible { get; set; }
    }
}

Sample 5: Initial Position

The InitialPositionLeft and InitialPositionTop properties can specify the initial distance from the left and top border of the browser viewport. You can use any CSS value here - e.g. 200px, 30% or 5vh.

page.dothtml
ViewModel.cs

<bp:ModalDialog IsDisplayed="{value: IsModalDisplayed}"
                InitialPositionLeft="50"
                InitialPositionTop="50">
    <p>I have custom position.</p>
</bp:ModalDialog>

<bp:Button Text="Show Modal Dialog with custom position"
           Click="{command: IsModalDisplayed = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample5
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsModalDisplayed { get; set; }
    }
}

Sample 6: Animations

The AnimationDuration property specifies the duration of the fade in and fade out effect. The value is in seconds.

page.dothtml
ViewModel.cs

<bp:ModalDialog IsDisplayed="{value: IsLongAnimationModalDisplayed}"
                AnimationDuration="1.5">
    <p>My animations are slow.</p>
</bp:ModalDialog>
<bp:Button Text="Show Modal Dialog with long animations"
           Click="{command: IsLongAnimationModalDisplayed = true}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.ModalDialog.sample6
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool IsLongAnimationModalDisplayed { get; set; }
    }
}
