GridView的多选操作
在DevExpress的GridControl中,可以通过以下步骤启用右键多选:
1. 设置GridControl的`MultiSelect`属性为`true`,以启用多选功能。
2. 在GridControl的事件`MouseDown`中判断鼠标右键是否按下,如果是,则选中当前行或单元格。
3. 在GridControl的事件`MouseMove`中判断鼠标左键是否按下,如果是,则根据鼠标移动的方向选择多个行或单元格。
4. 在GridControl的事件`MouseUp`中判断鼠标左键是否释放,如果是,则完成多选操作。
以下是示例代码:
```
private void gridControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hitInfo = gridView1.CalcHitInfo(e.Location);
if (hitInfo.InRow)
{
gridView1.SelectRow(hitInfo.RowHandle);
}
else if (hitInfo.InRowCell)
{
gridView1.SelectCell(hitInfo.RowHandle, hitInfo.Column);
}
}
}
private void gridControl1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hitInfo = gridView1.CalcHitInfo(e.Location);
if (hitInfo.InRow)
{
gridView1.FocusedRowHandle = hitInfo.RowHandle;
gridView1.SelectRange(gridView1.FocusedRowHandle, hitInfo.RowHandle);
}
else if (hitInfo.InRowCell)
{
if (hitInfo.RowHandle > gridView1.FocusedRowHandle)
{
gridView1.SelectRange(gridView1.FocusedRowHandle, hitInfo.RowHandle);
}
else
{
gridView1.SelectRange(hitInfo.RowHandle, gridView1.FocusedRowHandle);
}
}
}
}
private void gridControl1_MouseUp(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
gridView1.FocusedRowHandle = gridView1.GetSelectedRows()[0];
}
}
```
