SfTextBoxExt with textwrap does not resize properly

[Josepth Badrouk]

I have a SfTextBoxExt control that has the following properties: 

MaxLines="3", MaxCharacters="355", AutoNext="false", TextWrapping="TextWrapping.Wrap", AcceptReturn="true"

When entering text in the textbox and the text wraps as new lines are entered, the textbox height is being re-calculated properly when the text is cleared. However, if the textbox height is expanded and the splitter of the parent grid is resized, the textbox height does not correctly re-size itself. The expected behavior is that the textbox always correctly re-calculates the height accordingly.

Attached is a video illustrating the problem.

Hi Josepth Badrouk, 
 

Thank you for sharing the details and the video regarding the issue with the SfTextBoxExt control not resizing correctly after the parent grid's splitter is adjusted. 
 
Based on our review of the behavior shown in your recording, and the layout response after clearing the input, it appears that the issue might not be isolated to SfTextBoxExt alone. From the UI structure and animations, we suspect that the control might actually be wrapped inside a TextInputLayout 

To proceed accurately and avoid any misdiagnosis, we’d like to validate this with the actual XAML structure. Could you kindly share a minimal sample of your layout or code that includes: 

• The exact declaration of the SfTextBoxExt with its applied properties 
• The immediate parent layout/container 
• Whether it's embedded within any additional layout components (e.g., TextInputLayout, GridSplitter, etc.) 

This will help us reproduce the scenario as closely as possible to your setup and determine whether the issue lies in the control itself or how it's hosted. 
 
Looking forward to your response.

The SfTextBoxExt is embedded within a SfTextInputLayout. Without the SfTextInputLayout, this problem does not persist. However, this should still work even if embedded within a SfTextInputLayout. Here is the layout


    <Grid HorizontalAlignment="Stretch">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
        <syncfusion:SfTextInputLayout>
            <syncfusion:SfTextBoxExt MaxLines="3" MaxLength="355" TextWrapping="Wrap" AcceptsReturn="True" Margin="12,0,12,4">
            </syncfusion:SfTextBoxExt>
        </syncfusion:SfTextInputLayout>
    </Grid>
