Get label property

[Former Member]

Hi @ all,

I have a label and this has a caption. If I wanted before that this caption is dynamic, I bound a context attribute to it. So I could change the value of this attribute to change the caption.

But is it possible to access to the caption of a label in the implementation part without binding a context attribute to it?

Kind Regards

Dennis

Please make sure that you are passing the ID of the lable control to the .getElement() method.

Hi,

I found out that I was using a textview, not a label. Now the code doesn't give back any exceptions.

Thank you all for the help.

Hi Dennis,

You can do it through the implementation by using the following code.

    //Get the label object
    IWDLabel label = (IWDLabel)view.getElement("label");

    //Set the text of the label object
    label.setText("<<Some text>>");

    //Get the text of the label object
    String strCaption = label.getText();

You have to write the code in the "wdDoModifyView()".

Setting and getting the property of a UI element is advised to do using the context variables.

If you talk about IWDLabel, then IWDLabel.getText() gives you the text. This holds for the bound and unbound case.

Hi,

Try this in "wdDoModifyView" method

IWDLabel lbl=(IWDLabel)view.getElement("<<Label ID>>");

lbl.getText();
