Hi to all
I have this situatión, I have two screen, in the first one I have a text input in order the user type the name,one the user click the next button I filtered the information in the second screen, everything looks ok, the problem is when I return to the first screen I continue seeing the name of the user, how can I clear that information
Thank you
Solved! Go to Solution.
Ok, I see my error. Forget my first suggestion. That only works if you don't need that value in the textbox after typing it--i.e. clearing the username after someone clicks a button to login.
You can go with hngdev's suggestion if you want to carry the filtered table in a variable.
If you want to keep most things as they are, then you can try this:
Set Screen1.OnVisible to:
UpdateContext({resettext: !resettext}); UpdateContext({resettext: !resettext})
Set TextInput1.Reset to:
resettext
Set TextInput1.Default to:
""
Keep your filtered table the same.
This is how it works. Any time that you go to Screen1, the OnVisible actions will trigger. So it toggles the "resettext" variable to true, then back to false. The TextInput box will detect the change in the Reset property and reset the text to the Default value, which we set to "", which is blank.
If you navigate away from Screen1, the value in TextInput1 will stay the same. It will only reset when you go to Screen1.
Hi,
You can use following OnSelect action for a button (I use an "cancel" icon on the right side of the textbox):
Reset(TextBoxName)
The text input will be cleared and will shown default value or hint text.
Best regards
Hello,
I've created a Cookbook on how to clear a text input How to clear a text Input - Power Platform Community (microsoft.com).
You can also import the package to test it.
Hope it helps!

What you can try this:
It should work.
Here's another way I learned from the templates.
Set the TextInput.Reset property to:
Button1.Pressed
Whenever the button is pressed, that will reset the TextInput.Text to whatever the default is--which, in your case, is "".
Hi and thank you to both of you for the answers
I tested both suggestion and both worked fine but has a problem, when I clicl the button the information in the text input is erased and it can´t be sent to the second screen
Thank you
The way I approach is that I use a variable (filter) to store the text input data, when you click the button the Navigate function would wrap the filter variable and sent to the other screen. On the destination screen, you can use filter variable to get data.
Hi
But how and when do you store the value in a variable?
You can have a check over on my answer above.
I initialize the variable in Screen1's OnVisible
Then, assign the variable to the text input.
Then, wrap the variable storing text input data and navigate to Screen2
On Screen2, you can use the variable.
Ok, I see my error. Forget my first suggestion. That only works if you don't need that value in the textbox after typing it--i.e. clearing the username after someone clicks a button to login.

Hi
Option1:
Dang's suggestion is correct. Maybe the way it is triggered.
1. You enter Name (in screen 1) in TextInput1; set the Reset: Button2.Pressed
2. Click a button1 and navigate to Screen 2 (Button1, OnSelect: Navigate(Screen2, None))
3. Click a button2 and navigate back to Screen 1; (Button2: OnSelect: Navigate(Screen1, None))
4. In Screen1, you will see that TextInput1 entry is now cleared.
Reset: this can be triggered from another screen (global).
NB: When you click on Screen2 Button, the TextInput1 is cleared even before you navigate back to screen1.
Option 2:
You may also use UpdateContext, but this is local to the screen.
NB: When you click on Screen2 Button, the TextInput1 is cleared ONLY when you are in screen1 (you can see the test is cleared just when you navigate into screen1).
1. Insert a TextInput1 (in screen 1);
- under Default, say you name it: Default: MyText
- under OnVisible (Screen1), enter: OnVisible: UpdateContext({MyText: " "}); UpdateContext({MyText: ""}).
2. You enter Name (in screen 1) in TextInput1.
3. Click a button1 and navigate to Screen 2 (Button1, OnSelect: Navigate(Screen2, None))
4. Click a button2 and navigate back to Screen 1; (Button2: OnSelect: Navigate(Screen1, None))
5. In Screen1, you will see that TextInput1 entry is now cleared.
Always take note:
UpdateContext({MyText: " "}); UpdateContext({MyText: ""}).
" " - first one with space; "": second one with space.
Otherwise, you will never get your result.
They are numerous discussion over this with a lot of different options in Project Siena forum. https://social.technet.microsoft.com/Forums/en-US/de063751-7baa-41f0-af8d-20eb05126e40/how-do-i-clea...
Hoe this supplements the rests and helps.
Hi
Thank you very much for your help, finally It works, I followed the Dang's suggestion and now works as I espected
