Clear default textbox value when selected

Good evening,

I have a textbox with a default value, but if the value it's not correct, the user could change it.

What I want is if the user has to change the value, when he select the textbox the default value should disappear automatically. Now it's necessary to delete manually the default value and write the new one.

It's possible to do that?

I've tried with the Onselect property of the textbox and the blank() or Reset () function, but when I select the textbox it doesn't do anything...

Thanks,

Thank you Sik,

it's not the perfect solution, because you have to press de X button to clear the textbox, but if it's not possible to clear it when selected, it would work for me.

Thanks a lot for your time and our patience with me 😉

Hi @Biisorte ,

Do you mean you want to clear the TextInput box when you select it? How about the Clear function of TextInput box?
Please set the Clear property of TextInput box to true to enable the clear function.
Hope this helps.

Re: Clear default textbox value when selected

Thank you for your responses,

unfortunatelly, this solutions don't fit to me, because the default values are taken from a Sharepoint list, so I can use a variable to put the "" value.
I can't use either a button, because it's not viable to insert one button in each textbox.

I don't know why I cannot set the OnSelect property of the textbox to "". It would solve my problem...

Any other idea?

The workaround would be:
1. OnVisible of the Screen, set a variable:
   Set(MyReset,1)
2. Insert a button and a another textbox1
3. On the Button Onselect put: Set(MyReset2,MyReset+1)
4. In textbox1 default put: MyReset2
5. In your TextBox default, change the formula to:

If(Value(textbox1.Text)>1," ",PutYourDefaultValueHere)

@Biisorte

Yes, you can. As a demonstration of the technique try this:

Put this code in the OnVisible property of your screen

UpdateContext({myText: "Text You Want To Show"})

Use this code in the OnSelect property of your TextInput

UpdateContext({myText: ""})

Finally, change the Default property of the TextInput to

myText
