<SfButton @onclick="@GetCharCount">Get Char Count</SfButton>
<SfDialog @ref="DialogObj" @bind-Visible="@Visibility" Content="@Content" Header="@Header" Target="#target" Height="200px" Width="400px" ShowCloseIcon="true">

<SfRichTextEditor @ref="RteObj" @bind-Value="@RteValue"/>

@code {
    SfRichTextEditor RteObj;
    SfDialog DialogObj;
    private string Content;
    private bool Visibility = false;
    private string Header = "Rich Text Editor's Value";
    private string RteValue = @"<p>Rich Text Editor allows to insert images from online source as well as local computer where you want to insert the image in your content.</p><p><b>Get started Quick Toolbar to click on the image</b></p><p>It is possible to add custom style on the selected image inside the Rich Text Editor through quick toolbar.</p><img alt='Logo' style='width: 300px; height: 300px; transform: rotate(0deg);' src='https://cdn.syncfusion.com/ej2/richtexteditor-resources/RTE-Portrait.png' />";
    private async Task GetCharCount()
    {
        double charCount = await this.RteObj.GetCharCountAsync();
        this.Content = charCount.ToString(); // Convert double to string
        await this.DialogObj.ShowAsync();
    }
    private async Task DlgButtonClick(object arg)
    {
        await this.DialogObj.HideAsync();
