关于XtraGrid的使用（GridControl小结）

定义焦点行的方法： gridView_bcode.FocusedRowHandle = focuseRowInt; //通过设置GridView 的FocusedRowHandle属性

view plaincopy to clipboardprint?
//获取焦点行任意单元格的数据
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新获取此ID 否则无法从表头连删获取不到id
int focusedhandle = cv.FocusedRowHandle;
object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id");
if (DBNull.Value != rowIdObj)
{
FocusedRow_id = Convert.ToInt32(rowIdObj);
}
//获取焦点行任意单元格的数据
ColumnView cv = (ColumnView)gridControl_Gongzi.FocusedView;//重新获取此ID 否则无法从表头连删获取不到id
int focusedhandle = cv.FocusedRowHandle;
object rowIdObj = gridView1.GetRowCellValue(focusedhandle, "id");
if (DBNull.Value != rowIdObj)
{
FocusedRow_id = Convert.ToInt32(rowIdObj);
}
view plaincopy to clipboardprint?
//当数据发生变化时执行
private void gridView1_CellValueChanged(object sender, CellValueChangedEventArgs e)
{
int intRowHandle = e.RowHandle;
FocusedRow_bumen = Convert.ToString(gridView1.GetRowCellValue(intRowHandle, "bumen"));
FocusedRow_xingming = Convert.ToString(gridView1.GetRowCellValue(intRowHandle, "xingming"));
//FocusedRow_jibengongzi = Convert.ToDecimal(gridView1.GetRowCellValue(intRowHandle, "jibengongzi"));
object rowJibengongziObj = gridView1.GetRowCellValue(intRowHandle, "jibengongzi");
if (DBNull.Value != rowJibengongziObj)
{
FocusedRow_jibengongzi = Convert.ToDecimal(rowJibengongziObj);
}

}

view plaincopy to clipboardprint?
//焦点行的FocusedHandle为：
FocuseRow_Handle = -999998;
//获取焦点行的handle
ColumnView newview = (ColumnView)gridControl_Gongzi.FocusedView;

//回车添加新行

代码

private void gridView1_KeyPress(object sender, KeyPressEventArgs e)

{
if (e.KeyChar == 13)
{

newview.FocusedColumn = newview.Columns["bumen"];//定位焦点网格的位置

FocuseRow_Handle = newview.FocusedRowHandle;//获取新焦点行的FocuseRowHandle 并初始化全局变量FocuseRow_Handle供保存操作时判断是update还是insert
