Class FormFieldResizedEventArgs

Provides event data for the form field resized event in the SfPdfViewer2 component.

Inheritance

System.Object

FormFieldResizedEventArgs

Namespace: Syncfusion.Blazor.SfPdfViewer

Assembly: Syncfusion.Blazor.SfPdfViewer.dll

Syntax

public class FormFieldResizedEventArgs : Object

Remarks

The FormFieldResizedEventArgs class contains details about the form field that was resized, including its previous and updated dimensions, and the page number where the resize occurred. Developers can use this event data to track changes and implement custom logic for resizing restrictions.

Examples

<SfPdfViewer2 @ref="Viewer" Height="100%" Width="100%">
    <PdfViewerEvents FormFieldResized="@OnFormFieldResized"></PdfViewerEvents>
</SfPdfViewer2>

@code {
void OnFormFieldResized(FormFieldResizedEventArgs args)
{
    // Retrieve the resized form field
    FormFieldInfo resizedField = args.Field;
    Console.WriteLine($"Form field resized: {resizedField.Name}");

    // Retrieve old and new sizes
    Bound oldSize = args.OldBounds;
    Bound newSize = args.NewBounds;

    Console.WriteLine($"Old Size: {oldSize.Width}x{oldSize.Height}");
    Console.WriteLine($"New Size: {newSize.Width}x{newSize.Height}");

    // Implement additional logic
}
}

<SfPdfViewer2 @ref="Viewer" Height="100%" Width="100%">
    <PdfViewerEvents FormFieldResized="@OnFormFieldResized"></PdfViewerEvents>
</SfPdfViewer2>

@code {
void OnFormFieldResized(FormFieldResizedEventArgs args)
{
    // Retrieve the updated bounds of the form field
    Bound newBounds = args.NewBounds;
    Console.WriteLine($"New Bounds - X: {newBounds.X}, Y: {newBounds.Y}, Width: {newBounds.Width}, Height: {newBounds.Height}");

    // Implement additional logic
}
}

OldBounds

Gets the previous bounds of the form field before resizing in the SfPdfViewer2 component.

Declaration

public Bound OldBounds { get; }

Property Value

Type	Description
Bound	A Bound structure representing the form field position and dimensions before resizing.

Remarks

This property provides the position and dimensions of the form field before the resize event occurred. It helps track layout changes, enforce resizing constraints, and maintain a consistent user experience.

Examples

<SfPdfViewer2 @ref="Viewer" Height="100%" Width="100%">
    <PdfViewerEvents FormFieldResized="@OnFormFieldResized"></PdfViewerEvents>
</SfPdfViewer2>

@code {
void OnFormFieldResized(FormFieldResizedEventArgs args)
{
    // Retrieve the previous bounds of the form field
    Bound oldBounds = args.OldBounds;
    Console.WriteLine($"Old Bounds - X: {oldBounds.X}, Y: {oldBounds.Y}, Width: {oldBounds.Width}, Height: {oldBounds.Height}");

    // Implement additional logic
}
}

PageNumber

Gets the page number where the form field was resized in the SfPdfViewer2 component.

Declaration

public int PageNumber { get; }

Property Value

Type	Description
System.Int32	An System.Int32 representing the page number where the form field was resized.

Remarks

This property helps identify the location of the resized form field within the document.

<SfPdfViewer2 @ref="Viewer" Height="100%" Width="100%">
    <PdfViewerEvents FormFieldResized="@OnFormFieldResized"></PdfViewerEvents>
</SfPdfViewer2>

@code {
void OnFormFieldResized(FormFieldResizedEventArgs args)
{
    // Retrieve the page number where the form field was resized
    int pageNumber = args.PageNumber;
    Console.WriteLine($"Form field resized on page: {pageNumber}");

    // Implement additional logic
}
}
