Access specific toast in Blazor Toast Component

2 Aug 20212 minutes to read

In the toast, we can access the particular toast by passing the Key value in ShowModels, and the Key should be unique in ShowModels. To close the specific toast, you also need to pass the corresponding toast Key value in the Hide method. You can get the added Key value in the toast Opened and Closed event.

In the following example, Toast is closed by calling the Hide method with the key value that is returned in the Opened event

@using Syncfusion.Blazor.Notifications

<div id="target">
    <SfToast @ref="toast" ShowCloseButton="true" Height="150px" Width="200px" Timeout="60" Target="@target" Icon="e-meeting" Title="@title" >
        <ToastEvents Opened="OnOpen"></ToastEvents>
    <div class="col-lg-12 col-sm-12 col-md-12 center">
        <div id="toastBtnDefault" style="margin: auto;text-align: center">
            <button class="e-btn" id="toastBtnShow" @onclick="showOnclick">Show Toasts</button>
            <button class="e-btn" id="toastBtnHide" @onclick="hideOnclick">Hide All</button>
            <button class="e-btn" id="toastBtnHide" @onclick="HideOnclick">Hide</button>

    #toast_default .e-meeting::before {
        content: "\e705";
        font-size: 17px;

        SfToast toast;

        private string target = "#target";
        private string title = "This is Toast Title";

        private int key { get; set; } = 0;
        private async Task showOnclick()
            await this.toast.ShowAsync( new ToastModel {Key = key , Content = key.ToString() , Timeout = 10000 });

        private async Task OnOpen(ToastOpenArgs args)
            await this.toast.HideAsync(args.Key);

    private async Task HideOnclick()
        await this.toast.HideAsync();
    private async Task hideOnclick()
        await this.toast.HideAsync("All");
