Declaration

|---|---|---|

Returns
| Type | Description |
|---|---|
| DashboardBuilder | A reference to this instance after the operation has completed. |
Remarks
Use the BeforeRender event to access the underlying ASP.NET Core wrapper:
@(Html.DevExpress().Dashboard()
.Name("dashboardControl")
.Width("100%")
.Height("100%")
.OnBeforeRender("onBeforeRender")
)
The sender is the Web Dashboard’s underlying client part:
<head>
<script>
function onBeforeRender(sender) {
var dashboardControl = sender;
// Here you can customize a control.
}
</script>
</head>
You can now use its API to specify various client-side settings, perform actions, etc. See Client-Side Customization for information on how you can customize the client part of the Web Dashboard control.
