Xamarin forms: Increase the editor height based on the character count

I have an editor like below in my xamarin forms project.

enter image description here

When I type a message on it I need to increase the height of the editor based on the number of characters.

Here is my complete code of bottom part, I added a frame layout for making the entry corners are round:

<StackLayout

                HorizontalOptions="FillAndExpand"

                x:Name="tweetBox"

                VerticalOptions="End"

                Margin="0,0,0,10"

                BackgroundColor="#f2f2f2"

                Orientation="Horizontal">

Your code is working perfectly for me. Instead of executing, Provide Text properly & check in windows forms previewer.

@CGPA6.4 For me, the no change in the height of the entry, tried after removing the frame but no change. The text is going in a single line, no multiple lines are coming.

It is built-in to Xamarin.Forms now. Simply use the Editor control and set the AutoSize property to TextChanges. Note that the auto sizing will not work when you set a HeightRequest.

More information here: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/text/editor

Update: from the comments we resolved that replacing the StackLayout with a Grid helps you achieve the result. This is because a StackLayout just takes up the space that is (initially) taken up by its children. A Grid is able to grow dynamically.

Not working after adding autosize property. when typing message, the text is showing in the same line. Only a single line is showing, not going to the new line after completing the first line and no change in the editor height.

Try replacing your StackLayout with a Grid

I think nothing is built-in for this. Probably the OS will have some kind of maximum. Else you will need to hook into the SizeChanged event of the Editor and implement something for it yourself

It is built-in to Xamarin.Forms now. Simply use the Editor control and set the AutoSize property to TextChanges. Note that the auto sizing will not work when you set a HeightRequest.

Not working after adding autosize property. when typing message, the text is showing in the same line. Only a single line is showing, not going to the new line after completing the first line and no change in the editor height.

I created a sample project and this feature is working fine on there, but when I apply this to the main project it is not working. I added the entire code of my bottom part(+ image, editor and send icon) to the question, can you please check?

Try replacing your StackLayout with a Grid

I think nothing is built-in for this. Probably the OS will have some kind of maximum. Else you will need to hook into the SizeChanged event of the Editor and implement something for it yourself
