DxLoadingPanel.Visible Property

Specifies the Loading Panel’s visibility.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(false)]
[Parameter]
public bool Visible { get; set; }

Property Value

Type	Default	Description
Boolean	false	true to display the panel; otherwise, false.

Remarks

You can close the Loading Panel in the following ways:

• Use two-way binding with the Visible property to hide the panel on a condition (for example, when a time-consuming operation is completed).
• Allow users to close the panel from the UI. Enable the CloseOnClick option.

The following example imitates a time-consuming operation and uses the Visible property to show the panel at the beginning and hide it at the end of the operation:

<DxButton Click="Click">Start operation</DxButton>

<DxLoadingPanel @bind-Visible=@Visible
                ApplyBackgroundShading="true"
                CssClass="w-100">
    <DxMemo @bind-Text="@Text"
            Rows="10" />
</DxLoadingPanel>

@code {
    bool Visible { get; set; } = false;
    private async Task Click() {
        Visible = true;
        await Task.Delay(3000);
        Visible = false;
    }
