ModalDialog

in namespace DotVVM.Framework.Controls.Bootstrap4

Renders the Bootstrap modal dialog widget.

Usage & Scenarios

Renders a modal dialog popup displayed on top of the current page using Bootstrap Modal widget.

https://getbootstrap.com/docs/4.3/components/modal/

Sample 1: Basic Usage

The ModalDialog control has the HeaderText property which sets the title of the popup.

By default, the dialog title is rendered as <h4> header, but you can adjust it using the HeaderTagName property. If you need to customize the header using your own HTML content, use the HeaderTemplate property instead.

The contents of the dialog are specified using the ContentTemplate property. This is the only required property.

The button row can be customized using the FooterTemplate property.

The ModalDialog can be displayed or hidden using the IsDisplayed property. Just bind it to a bool property in the viewmodel and set it to true or false.

Closing the dialog by clicking outside of it or by pressing the Escape key will set the IsDisplayed property to false.

page.dothtml
ViewModel.cs

<bs:Button Text="Open Dialog" Type="Primary" Click="{command: OpenDialog()}" />

<bs:ModalDialog IsDisplayed="{value: Displayed}">
  <HeaderTemplate>
    My Dialog
    <bs:CloseButton/>
  </HeaderTemplate>
  <ContentTemplate>
    This is the contents of the dialog.
  </ContentTemplate>
</bs:ModalDialog>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ModalDialog.sample2
{
    public class ViewModel
    {
        public bool Displayed { get; set; } = false;

        public void OpenDialog() 
        {
            Displayed = true;
        }
    }
}

Sample 2: ModalDialog Static Commands

You can use a Static Command to control the IsDisplayed property.

No communication with the server is required in this mode because you only work with the viewmodel property.

page.dothtml
ViewModel.cs

<bs:Button Text="Open Dialog" Click="{staticCommand: Displayed = true}" />

<bs:ModalDialog HeaderText="My Dialog" 
                IsDisplayed="{value: Displayed}">
	<ContentTemplate>
		This is the dialog.
	</ContentTemplate>
	<FooterTemplate>
		<bs:Button Text="Close Dialog" Click="{staticCommand: Displayed = false}" />
	</FooterTemplate>
</bs:ModalDialog>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ModalDialog.sample2
{
    public class ViewModel
    {
        public bool Displayed { get; set; } = false;
    }
}

Sample 3: ModalDialog Sizing and Styles

The Size property allows to define the size of the modal dialog - Small, Normal, Large and ExtraLarge .

If the modal dialog lays over other elements in the page, you may want to modify the ZIndex property.

The UseBackdrop indicates whether the modal backdrop should be rendered under the modal dialog.

The CrollableContent sets whether the modal dialog content would be vertically scrollable.

The CloseOnBackdropClick or CloseOnEscape properties allows to specify whether the dialog should be closed by clicking outside of it or by pressing the Escape key.

If AddCloseButton is set to true, the CloseButton control will be added to the modal dialog header.

page.dothtml
ViewModel.cs

<bs:Button Text="Open Dialog" Click="{staticCommand: Displayed = true}" />

<bs:ModalDialog HeaderText="My Dialog" 
                IsDisplayed="{value: Displayed}"
				Size="Small"
				AddCloseButton="true"
				CloseOnEscape="false"
				CloseOnBackdropClick="false"
				UseBackdrop="false"
				CrollableContent="true" >
	<ContentTemplate>
		This is the dialog.
	</ContentTemplate>
	<FooterTemplate>
		<bs:Button Text="Close Dialog" Click="{staticCommand: Displayed = false}" />
	</FooterTemplate>
</bs:ModalDialog>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ModalDialog.sample2
{
    public class ViewModel
    {
        public bool Displayed { get; set; } = false;
    }
}
