determine whether the text has been changed, ( is dirty, modified)

[otto]

Is there a build in flag to signal whether the text has been altered? Or even an event?

Hi Otto, 

 

Greetings from Syncfusion support, 

 

We have validated your reported query. Yes, we have an event ValueChange for detecting the Value changes in the editor. If the SaveInterval property, is set as 1 and binding the event will trigger the change event immediately for the editor. By default, if the SaveInterval property is not configured the ValueChange event will be triggered after an timeout of 10000. Check the below code blocks for reference. 

  

  

@using Syncfusion.Blazor.RichTextEditor  

  

<SfRichTextEditor @ref="RteObj" SaveInterval=1>  

    <RichTextEditorEvents ValueChange="@onChanged"></RichTextEditorEvents>  

    <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>  

</SfRichTextEditor>  

  

@code {  

    SfRichTextEditor RteObj;  

    public void onChanged()  

    {  

        System.Diagnostics.Debug.WriteLine(this.RteObj.Value);  

    }  

}  

  

   

Please let us know if the solution helps,

Thank you for your quick Reply. 

But:

What I'm missing there?

Hi Otto, 

 

We have checked the shared screenshot. The event ValueChange binding, must be in the separate RichTextEditorEvents tag. You have binded the event in the SfRichTextEditor editor tags. Modify the code blocks, like below and check the reported issue. 

 

 

@using Syncfusion.Blazor.RichTextEditor   

   

<SfRichTextEditor @ref="RteObj" SaveInterval=1>   

    <RichTextEditorEvents ValueChange="@onChanged"></RichTextEditorEvents>   

    <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>   

</SfRichTextEditor>   

   

@code {   

    SfRichTextEditor RteObj;   

    public void onChanged()   

    {   

        System.Diagnostics.Debug.WriteLine(this.RteObj.Value);   

    }   

}

Hi Indrajith,

perfect. the case is settled. as I suspected the fault was on my part. what I missed: the separation of object and object events was not clear to me.

thank you for your good work. I appreciate that.

best regards, otto
