ValueChanged event is not working as expected

[Adriana Selena Tito Ilasaca]

Hi there, 

Working with TextBox component and ValueChanged event I noticed ValueChanged event is not being fired when I start typing into the TextBox component. I know the difference between ValueChanged and ValueChange is that ValueChange is triggered when you focusout the textBox but ValueChanged when the value of the TextBox changes.
Is this a bug? Also I saw there is OnInput event is there any difference with ValueChanged?

Hi Adriana, 

Thanks for contacting Syncfusion support. 

Query: I noticed ValueChanged event is not being fired when I start typing into the TextBox component. 

 

The ValueChanged event will not be fired when start typing. Because, we would like to know you that both the ValueChange and ValueChanged event triggers when focus out the component and the difference between them is the ValuChanged event contains the only argument with changed value and ValueChange event is triggered with arguments of previous value and current value and whether the value has changed programmatically or user interacted. 

So, as per your requirement to get the event when start typing is Input event, which fired each time when the value of TextBox has changed. 

https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Inputs.SfTextBox.html#Syncfusion_Blazor_Inputs_SfTextBox_Input 

Events	Description	Arguments
Input	Triggers each time when the value of TextBox has changed.
ValueChanged	Specifies the callback to trigger when the value changes.
valueChange	Triggers when the content of TextBox has changed and gets focus-out.

Hello,

However if you use SfMaskedTextBox then the ValueChanged event is being fired after typing every character and I have based my application logic on it. Can you explain what is the correct behavior?

Hi Lukasz, 

 

In our maskedtextbox component we need to validate given character is matching or not in mask property, so the change event triggered after every key inserted. Which is the reason the ValueChanged event is being fired after typing every character. But previously updated response is related to textbox component.  This is the correct behavior of masked textbox component.
