dev 控件之 gridcontrid 应用

一、gridview 新增一行有两种:

   1.gridView.AddNewRow()然后在gridView_InitNewRow事件里面填写新添加行的数据。

     

private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e) //添加一行后触发事件,赋值
{
    ColumnView View = sender as ColumnView;

    
    View .SetRowCellValue(e.RowHandle, "UserName", addusername);
    View .SetRowCellValue(e.RowHandle, "LoginName", addloginname);
    gridView1.FocusedRowHandle = e.RowHandle;

}

2. 直接在 数据源里面赋值,及datatable里面。

datatable  table = new datatable();

gridcontrid.datasource = table;

DataRow newrow = usertable.NewRow();
newrow["UserName"] = addusername;
newrow["LoginName"] = addloginname;
usertable.Rows.Add(newrow);
gridView1.FocusedRowHandle = gridView1.RowCount - 1;

二、gridview界面上的修改删除操作

修改:gridView1.SetFocusedRowCellValue("UserName",editForm.returuserName);

删除:gridView1.DeleteRow(deletehandle[i]);   //删除一行

   gridView1.DeleteSelectedRows();    //删除选中的所有行

三 gridview属性设置

列头禁止移动 :  设置gridView1.OptionsCustomization.AllowColumnMoving = false;

列头禁止排序:    设置gridView1.OptionsCustomization.AllowSort = false;.

隐藏最上面的GroupPanel  :gridView1.OptionsView.ShowGroupPanel=false;

数据只读  :gridView1.OptionsBehavior.Editable=false;

只读可拷贝:
    ColumnViewOptionsBehavior.Editable = True
    OptionsColumn.AllowEdit = True
    OptionsColumn.ReadOnly = True

 可编辑:
    ColumnViewOptionsBehavior.Editable = True
    OptionsColumn.AllowEdit = True
    OptionsColumn.ReadOnly = False

得到单元格数据(0行0列):
   string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);
   string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);

设置单元格数据(将0行0列的单元格赋值123):
   gridView1.SetRowCellValue(0, gridView1.Columns[0],"123");
