Blazor Dock Manager Overview
The Infragistics Blazor Dock Manager provides a means to manage the layout of your application through panes, allowing your end-users to customize it further by pinning, resizing, moving, maximizing and hiding panes.
Blazor Dock Manager Example
This example shows most functionalities and docking options of the IgbDockManager that you can use in your application.
Customization
The Dock Manager component provides the option to customize all buttons using slots and parts. To change any of the buttons you simply have to define your own element inside the Dock Manager and set the slot attribute to the corresponding identifier.
Let's utilize these slots and parts to create a customized Dock Manager layout. First, we will provide our own icons, using the closeButton, maximizeButton, minimizeButton, pinButton and unpinButton slots:
Then, we will use the exposed parts in our stylesheet. This way we have full control of the component's styling:
igc-dockmanager::part(unpinned-tab-area) {
background: #bee9ec;
}
igc-dockmanager::part(unpinned-tab-area--left) {
border-right: 1px dashed #004d7a;
}
igc-dockmanager::part(unpinned-tab-area--bottom) {
border-top: 1px dashed #004d7a;
}
igc-dockmanager::part(tab-header-close-button),
igc-dockmanager::part(pane-header-close-button) {
background-color: #e73c7e;
}
igc-dockmanager::part(pane-header-pin-button),
igc-dockmanager::part(pane-header-unpin-button) {
background: rgb(218, 218, 218);
border: none;
width: 24px;
height: 24px;
color: #fff;
}
igc-dockmanager::part(tabs-maximize-button),
igc-dockmanager::part(tabs-minimize-button),
igc-dockmanager::part(pane-header-minimize-button),
igc-dockmanager::part(pane-header-maximize-button) {
width: 24px;
height: 24px;
border: none;
transition: opacity 250ms ease-in-out;
opacity: 0.3;
margin-right: 15px;
margin-top: -5px;
margin-left: 0px;
}
If everything went well, we should now have a DockManager with customized icons and tab area. Let's have a look at it:
