我正在尝试在C#WinForm中滚动到DataGridView的底部。
此代码适用于TextBox:
textbox_txt.SelectionStart = textbox_txt.Text.Length;
textbox_txt.ScrollToCaret();
...但我不知道如何使用DataGridView。有什么帮助吗?

要滚动到DataGridView
的底部,请尝试此操作。
dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.RowCount-1;

作为一名商业程序员,我使用C#DLL处理我的所有DataGridView项目,这使我能够为我承担的任何项目提供语言自由。我的所有程序都会捕获所有按键,以便我可以将它们用于我自己的目的。对于DataGridView滚动,我使用PageUp / PageDown键作为单页,Ctrl / Page作为单行,Alt / Page作为top(Up)和bottom(Down)。 C#代码和基本调用顺序如下:
//---------- C# Dll Partial Source -----------
public int RowShow
{ get { return vu.DisplayedRowCount(false); } }
public int RowCount
{ get { return vu.RowCount; } }
public void PageMove(int rows)
{
int rowlimit = vu.RowCount - 1;
int calc = vu.FirstDisplayedScrollingRowIndex + rows;
if (calc > rowlimit) calc = rowlimit; // Go to bottom
if (calc < 0) calc = 0; // Go to top
vu.FirstDisplayedScrollingRowIndex = calc;
}
// ---------- End Data Grid View ----------
//---------- Calling Program C# ----------
public void Page_Key(int val, int lastKey)
{
int inc = 1; // vu is DataGridView
If (val == 33) inc = -1;
int rowsDisp = vu.RowShow; // # of rows displayed
int rowsMax = vu.RowCount; // # of rows in view
int rows = 0;
switch (lastKey)
{
case 17: // Ctrl prior to Page
rows = inc;
break;
case 19: // Alt prior to Page
rows = rowsMax * inc;
break;
default:
rows = rowsDisp * inc
break;
} // end switch
vu.PageMove(rows)
} // end Page_Key
'----- Calling Program B4PPC, VB -----
Sub Page_Key(val,lastKey) ' 33=PageUp, 34=Down
inc = 1 ' vu is DataGridView
If val = 33 then inc = -1
rowsDisp = vu.RowShow ' # of rows displayed
rowsMax = vu.RowCount ' # of rows in view
rows = 0
Select lastKey
Case 17 ' Ctrl prior to Page
rows = inc
Case 19 ' Alt prior to Page
rows = rowsMax * inc
Case Else
rows = rowsDisp * inc
End Select
lastKey = ""
vu.PageMove(rows)
End Sub
