SfTextbox Created event args are always null
Hello,
I have a simle textbox:
<SfTextBox TabIndex="1" @ref="textbox0" ID="textbox" @bind-Value="_testModel.Value1" Created="CreatedHandler"></SfTextBox>
private void CreatedHandler(Object args)
{
// args null here
}
I would like access to the control inside the CreateHandler method dynamically, so not at this way: textbox0.[xy]
I would like access to the source control trough the args object, but it is always null.
In my future plan I have 5 textbox controls that uses the same Created event and I need access to tabindex value inside CreatedHandler method.
Thank you for help!

Hi SZL,
As you requested we have created a sample that has 5 textbox controls that use the same Created event and we can access to tabindex value inside the CreatedHandler method. Please find the code snippet and sample below.
<SfTextBox TabIndex=0 @ref="textbox0" ID="textbox1" @bind-Value="_testModel.Value1" Created="(args) => CreatedHandler(args,textbox0)"></SfTextBox>
<br /> <SfTextBox TabIndex=1 @ref="textbox1" ID="textbox2" @bind-Value="_testModel.Value2" Created="(args) => CreatedHandler(args,textbox1)"></SfTextBox>
<br /> <SfTextBox TabIndex=2 @ref="textbox2" ID="textbox3" @bind-Value="_testModel.Value3" Created="(args) => CreatedHandler(args,textbox2)"></SfTextBox>
@code{ SfTextBox textbox0; SfTextBox textbox1; SfTextBox textbox2;
TextModel _testModel = new TextModel(); public class TextModel { public string Value1; public string Value2; public string Value3;
} private void CreatedHandler(Object args,SfTextBox textBoxRef) { var Tabindex = textBoxRef.TabIndex; } }

Thank you, this will be good.
In the future you will not add the sender object to the args parameter to the Created event? (feature request)
In this case the code will be much sorter and not need create reference objects.
Thank you!
