C# 如何创建类似于谷歌图片的WPF布局
我正在尝试创建一个用户界面,它模仿谷歌图像的行为,当单击一个平铺时,图像所在行下方的“行”中的图像,而不会导致行中的其余元素移动 这就是我所能做到的。可以将以下用户控件添加到WrapPanel,当用户单击第一个StackPanel时,PdfViewerWrapperGrid应该出现:C# 如何创建类似于谷歌图片的WPF布局,c#,wpf,user-interface,C#,Wpf,User Interface,我正在尝试创建一个用户界面,它模仿谷歌图像的行为,当单击一个平铺时,图像所在行下方的“行”中的图像,而不会导致行中的其余元素移动 这就是我所能做到的。可以将以下用户控件添加到WrapPanel,当用户单击第一个StackPanel时,PdfViewerWrapperGrid应该出现: <UserControl x:Class="APDesktop.Controls.PdfAttachment" xmlns="http://schemas.microsoft.com/win

我最终使用了前面建议的网格。这当然是一种手动方法,涉及代码隐藏中的两个主要方法。希望这对其他人有帮助 第一个计算每个磁贴的适当行和列位置:
private void ReDrawAttachmentsGrid()
{
foreach (var child in AttachmentsPanel.Children)
{
if (child is PdfAttachment)
{
var childAsPdfAttachment = child as PdfAttachment;
var indexOfAttachment = PdfAttachments.IndexOf(childAsPdfAttachment);
var tilesPerRow = (int)Math.Floor(AttachmentsOuterGrid.ActualWidth / 112);
var desiredRowIndex = (int)(indexOfAttachment / tilesPerRow);
desiredRowIndex += desiredRowIndex;
var desiredColumnIndex = (int)(indexOfAttachment % tilesPerRow);
if (AttachmentsPanel.RowDefinitions.Count - 1 < desiredRowIndex)
{
while (AttachmentsPanel.RowDefinitions.Count - 1 < desiredRowIndex)
AttachmentsPanel.RowDefinitions.Add(new RowDefinition());
}
if (AttachmentsPanel.ColumnDefinitions.Count - 1 < desiredColumnIndex)
{
var column = new ColumnDefinition();
column.Width = new GridLength(112);
AttachmentsPanel.ColumnDefinitions.Add(column);
}
Grid.SetColumn(childAsPdfAttachment, desiredColumnIndex);
Grid.SetRow(childAsPdfAttachment, desiredRowIndex);
}
}
private void重画attachmentsgrid()
{
foreach(附件中的变量child.Children)
{
if(儿童为PdfAttachment)
{
var childAsPdfAttachment=作为PdfAttachment的子对象;
var indexOfAttachment=PdfAttachments.IndexOf(childAsPdfAttachment);
var tilesPerRow=(int)数学楼层(附件SOUTERGRID.ACTUALLWIDTH/112);
var desiredRowIndex=(int)(indexOfAttachment/TileSprrow);
desiredRowIndex+=desiredRowIndex;
var desiredColumnIndex=(int)(indexOfAttachment%TileSprrow);
if(附件spanel.RowDefinitions.Count-1
第二个显示了一个查看器,位于正在单击的查看器下方的行上,如下所示:
var pdfViewer = new PdfViewer(e.Images, e.ByteArray, e.DisplayName, e.AttachmentKey);
pdfViewer.AttachmentClosed += pdfViewer_AttachmentClosed;
AttachmentsPanel.Children.Add(pdfViewer);
Grid.SetColumnSpan(pdfViewer, 100);
var desiredRowIndex = Grid.GetRow(senderAsPdfAttachment) + 1;
if (AttachmentsPanel.RowDefinitions.Count - 1 < desiredRowIndex)
{
while (AttachmentsPanel.RowDefinitions.Count - 1 < desiredRowIndex)
AttachmentsPanel.RowDefinitions.Add(new RowDefinition());
}
Grid.SetRow(pdfViewer, desiredRowIndex);
var pdfViewer=新的pdfViewer(e.Images,e.ByteArray,e.DisplayName,e.AttachmentKey);
pdfViewer.AttachmentClosed+=pdfViewer\u AttachmentClosed;
附件spanel.Children.Add(pdfViewer);
Grid.SetColumnSpan(pdfViewer,100);
var desiredRowIndex=Grid.GetRow(senderAsPdfAttachment)+1;
if(附件spanel.RowDefinitions.Count-1
还有……有什么问题吗?具体来说,你被卡在哪里了?当PdfViewerWrapperGrid可见时,其他项目会被推到一边或包装。我不希望其他同级项目的位置发生变化。不幸的是,你在该项目中有大量我没有的资源,因此我很难复制你的项目。解决方案如下:我想到的是使用一个简单的网格
,然后通过展开行定义
来设置动画height@DanielWard-是的,我现在将其实现为一个网格。缺点是,这会导致比我想要的更多的代码隐藏和更少的绑定。优点是它将完全按照预期运行。您可以实现t扩展和它的动画没有任何代码隐藏(除了转换器):。我为扩展器
实现了一次,但将其应用于行定义
