    Default Extjs 3.4 textarea height reset

    Extjs 3.4 textarea height reset


    Hi,

    I want to reset the height of auto growing textarea to its original height once it is set to empty. But because of the "emptyText", textarea expands itself.
    Is there any way to configure textarea so that it does not consider "emptyText" for expending height.

    Thanks...

    Well this is a 4.1 forum but...

    If it grows to fit the text then you can set a new Height with getHeight(defaultHeight)

    Or override this function to you needs

    Code:
    setValue : function(v){
            if(this.emptyText && this.el && !Ext.isEmpty(v)){
                this.el.removeClass(this.emptyClass);
            }
            Ext.form.TextField.superclass.setValue.apply(this, arguments);
            this.applyEmptyText();
            this.autoSize();
            return this;
        },
    Switch the order
    Code:
    this.autoSize();
    this.applyEmptyText();
    First autosize then set emptytext
