In the following code snippet, the toggle Button text changes to play/pause based on the state of the Button with the use of OnClick event.

@using Syncfusion.Blazor.Buttons

<SfButton CssClass="e-flat" IsPrimary="true" IconCss="@IconCss" Content="@Content" IsToggle="true" @onclick="OnToggleClick" @ref="ToggleBtnObj"></SfButton>

@code {
    SfButton ToggleBtnObj;
    public string IconCss = "e-icons e-play";
    public string Content = "Play";
    public void OnToggleClick()
        if(ToggleBtnObj.Content == "Play")
            this.Content = "Pause";
            this.IconCss = "e-icons e-pause";
            this.Content = "Play";
            this.IconCss = "e-icons e-play";
