1.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]);

2.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");

3.手动添加dev的列

DevExpress.XtraGrid.Columns.GridColumn Col1=new DevExpress.XtraGrid.Columns.GridColumn ();
Col1.FieldName="FID";
Col1.Visible=true;
Col1.VisibleIndex=gridView1.Columns.Count;
gridView1.Columns.Add(Col1);

4.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator

private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
if (e.Info.IsRowIndicator && e.RowHandle >= 0)
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}

5.删除: (修改了dgvdel里的datagridviewdel方法)

public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)
{
if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)
{
int iSelectRowCount = Mydgv.SelectedRowsCount;
if (iSelectRowCount > 0)
{
Mydgv.DeleteSelectedRows();
}
}
}

6.新增: (对于新增,其本身的AddNewRow方法就可以做到)

private void btn_add_Click(object sender, EventArgs e)
{
gridView1.AddNewRow();
}
具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写:
private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
{
ColumnView View = sender as ColumnView;
View.SetRowCellValue(e.RowHandle, View.Columns[0], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[0])); //复制最后一行的数据到新行

View.SetRowCellValue(e.RowHandle, View.Columns[1], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[1])); //复制最后一行的数据到新行

}

7.保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以

8.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、Advanced BandedView、LayoutView；共5种。

1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了

2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角

3）、Roll Angle 属性决定着 倾侧角度

4）、指定数据源，显示数据：

//显示数据
private void showData(List<Employee > list)
{
DataTable dt = new DataTable("OneEmployee");
dt.Columns.Add("Caption", System.Type.GetType("System.String"));
dt.Columns.Add("Department", System.Type.GetType("System.String"));
dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

for (int i = 0; i < list.Count; i++)
{
DataRow dr = dt.NewRow();
dr["Caption"] = list[i].Name;
dr["Department"] = list[i].Department;
string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;
dr["PhotoName"] = getImageByte(imagePath);
dt.Rows.Add(dr);
}
gridControl1.DataSource = dt;
}

//返回图片的字节流byte[]
private byte[] getImageByte(string imagePath)
{
FileStream files = new FileStream(imagePath, FileMode.Open);
byte[] imgByte = new byte [files.Length ];
files.Read(imgByte, 0, imgByte.Length);
files.Close();
return imgByte;
}
