问题描述
大家好,
我在每一行的第一列中都有DataGridView(DGV)[使用DGV.GetCellDisplayRectangle(...)方法)我放置了UserControl(UC).但是,当行数增加时,它会将滚动条添加到DGV
然后我无法将UC移动到滚动位置,因为DGV.GetCellDisplayRectangle(...)每次都会返回Rectangle.X = 0和Rectangle.Y = 0(如果DGV.Cell是可见的). >
为什么?现在如何解决这个问题?
Hi All,
I have DataGridView(DGV) in its 1st column of every row [with DGV.GetCellDisplayRectangle(...) menthod) I placed UserControl(UC). But when row counts increases it adds scroll to DGV
And then i''m not able to move UC to scrolled location, Because DGV.GetCellDisplayRectangle(...) returns Rectangle.X = 0 and Rectangle.Y=0 every time (If DGV.Cell is visible).
Why? Now how to solve this problem?
void dgvMapper_Scroll(object sender, ScrollEventArgs e)
{
int intCnt = 0;
foreach (UserControl ucEL)
{
ucEL.Visible = false;
Rectangle rect = this.dgvMapper.GetCellDisplayRectangle(1, intCnt, false);
ucEL.Location = rect.Location;
ucEL.Size = rect.Size;
if (!(rect.X==0 && rect.Y==0 && rect.Height==0))
ucEL.Visible = true;
intCnt++;
}
}
}
