Change Default Value of Text Input via OnSelect command

[Joaoleaga]

Hello, 

I need help building an 'OnSelect' command that changes the default value of a 'Text Input' field in my app.

Here is more background.  I have a 'Text Input' field (numberic) with a default value of "0" and maximum character lenght of 2.  See attachment.

Users are complaining that when trying to enter a new value,  the "0" default value apears in the screen and it requires to do a backspace before being able to enter the new value.  This is making it unfriendly for user to enter values.  

Is there an OnSelect command that I can add to the Text Input field that would change the default value to blank or ("") ? ???

Help!

Hi!

You can put a Context Variable on the Default property of the TexBox, then change its value from OnSelect property of another control.

Hi Dariobois,

Thanks for your prompt response.  I like your suggestion.  But how don't know how to set the variable to the number 0.  I am only familiar with setting variables to true or false.

You mind taking a look at the sentence in the screen shot to see what I am doing wrong? (varDefault0 = Number:0)

Hi!

Just like this

Then, use this formula when you want to put a value into textbox. In OnVisible property of that screen, for example.

UpdateContext ({varDefault: 123123123}) 

Replace "123123123" with a value you want or, take it from another textbox for example.

Regards!
