触摸屏 - DataGridView不滚动到最后 [英] Touch screen - DataGridView not scrolling to the end

问题描述

我有一个应用程序在触摸屏上运行。在我有一个DataGridView，我有这个问题：

当我使用触摸屏scrool它不会结束。

当我使用鼠标使用鼠标时，它会结束。

由于我上次触摸屏相关的问题没有得到太多的爱或回答我制作了一个视频，以更好地展示我的问题：链接到视频

如你所见，当我使用触摸屏时，有一个记录缺失，当我用鼠标进入scrool吧，就像DataGridView添加了另一条记录。这是不止一行。

任何建议？

编辑：

现在我正在尝试这个，但它仍然是不可预测的

  int totalHeight = 0; 
 foreach（dataGridView1.Rows中的DataGridViewRow行）
 totalHeight + = row.Height; 
 
 MessageBox.Show（Total H：+ totalHeight.ToString（）+Height：+ dataGridView1.Height.ToString（）+VO：+ dataGridView1.VerticalScrollingOffset）; 
 
 if（totalHeight  -  dataGridView1.Height< dataGridView1.VerticalScrollingOffset）
 {
 int diferenca = dataGridView1.RowCount  - （dataGridView1.FirstDisplayedScrollingRowIndex + dataGridView1.DisplayedRowCount（false））; 
 
 MessageBox.Show（Diferenca-+ diferenca.ToString（）+RowCount-+ dataGridView1.RowCount +Soma-+（dataGridView1.FirstDisplayedScrollingRowIndex + dataGridView1.DisplayedRowCount（false））） ; 
 
 if（diferenca！= 0）
 {
 dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.FirstDisplayedScrollingRowIndex + diferenca; 
} 
} 
  

解决方案

尝试通过设置VerticalScrollingOffset来编程地执行此操作：

I have an application running on a touch screen. In it i have a DataGridView, and i have this problem:

When i scrool it using the touch screen it does not go to the end.

When i scrool it using the mouse it does go to the end.

Since my last touch screen related question did not get much love or answer i made a video to better demonstrate my problem: LINK TO THE VIDEO

As u can see, when i use the touch screen there is a record missing and when i go to the scrool bar with the mouse its like the DataGridView adds another record. This has happen with more than just 1 row.

Any suggestions ?

Info:

App is running on win 10. Made in .net(c#)(framework 4)

EDIT:

right now i am trying this but its still too unpredictable

            int totalHeight = 0;
            foreach (DataGridViewRow row in dataGridView1.Rows)
                totalHeight += row.Height;

            MessageBox.Show("Total H: " + totalHeight.ToString() + " Height: " + dataGridView1.Height.ToString() + " VO: " + dataGridView1.VerticalScrollingOffset);

            if (totalHeight - dataGridView1.Height < dataGridView1.VerticalScrollingOffset)
            {
                int diferenca = dataGridView1.RowCount - (dataGridView1.FirstDisplayedScrollingRowIndex + dataGridView1.DisplayedRowCount(false));

                MessageBox.Show("Diferenca- " + diferenca.ToString() + "RowCount- " + dataGridView1.RowCount + "Soma- " + (dataGridView1.FirstDisplayedScrollingRowIndex + dataGridView1.DisplayedRowCount(false)));

                if (diferenca != 0)
                {
                    dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.FirstDisplayedScrollingRowIndex + diferenca;
                }
            }

解决方案

Try to do it programatically by setting VerticalScrollingOffset:
