devexpress
有谁能提供一些 devexpress组件的用法，最好有视频，呵呵，谢谢了，最好有cxgrid的详细介绍哦 --------------------编程问答-------------------- 怎么给你呢？
--------------------编程问答-------------------- 可以发到我的邮箱吗，451290601@qq.com 谢谢了
呵呵 --------------------编程问答-------------------- --------------------编程问答-------------------- 设置行号
gridView1.IndicatorWidth = 30;
private void gridView1_CustomDrawRowIndicator_1(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
if (e.Info.IsRowIndicator)
{
if (e.RowHandle >= 0)
{
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
else if (e.RowHandle < 0 && e.RowHandle > -1000)

代码实现方法
gridView1.OptionsView.ShowGroupPanel = false;
控件实现方法
设置某列不可编辑和只读
gridView1.Columns[0].OptionsColumn.AllowEdit = false;
gridView1.Columns[0].OptionsColumn.ReadOnly = false;
设置模板
以下为步骤
首先从In-Place Editor Repository中添加LookUpEdit.取名为re_User
他的Columns属性中添加2列.Caption依次为:编号,姓名FieldName依次为:User_code,User_Name然后将Re1的NullText设置成空.
AutoSearchColumnIndex属性设置为2.
ImmediatePopup属性设置为True.
SearchMode设置为OnlyInPopup.
然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)
最后我们还要在代码里面给Re1绑定数据源和显示项.
re_user.DataSource=new T8002().getT8002().Tables[0];
re_user.DisplayMember = "USER_NAME";
re_user.ValueMember = "USER_CODE";
*:对于Oracle数据库字段一定要用大写,切记!!
Dev中的属性Table
/// <summary>
/// 机场图管理表的状态
/// </summary>
/// <returns></returns>
public DataTable TypeTable()
{
DataTable dt = new DataTable();
dt.Columns.Add("S_TYPE");
dt.Columns.Add("S_TYPE_NAME");
DataRow row = dt.NewRow();
row["S_TYPE"] = "0";
row["S_TYPE_NAME"] = "正常";
dt.Rows.Add(row);
row = dt.NewRow();
row["S_TYPE"] = "1";
row["S_TYPE_NAME"] = "删除";
dt.Rows.Add(row);
return dt;
}
使新添加的行在 gridView1 的第一行
//使新添加的行在 gridView1 的第一行
gridView1.OptionsView.NewItemRowPosition = DevExpress.XtraGrid.Views.Grid.NewItemRowPosition.Top;
gridView1.AddNewRow();
初始化新行的数据
private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
{
ColumnView View = sender as ColumnView;
View.SetRowCellValue(e.RowHandle, "SEQ_I7101", (int)DataSetProvider.GetSequenceSeed("seq_i7101"));
View.SetRowCellValue(e.RowHandle, "S_TYPE", "0");
}
子窗体字段刷新父窗体（注意加大加粗字体部分）
父窗体
private void btnAdd_Click(object sender, EventArgs e)
{
FrmBaseInfo_img_01 frm = new FrmBaseInfo_img_01();
if (frm.ShowDialog() == DialogResult.OK)
{
if (dt.Select("I7101='" + frm.ID + "'").Length > 0)
{
dt.Select("I7101='" + frm.ID + "'")[0]["AIRPORT_4CODE"] = frm.CODE;
dt.Select("I7101='" + frm.ID + "'")[0]["PIC_CODE"] = frm.PIC_CODE;
dt.Select("I7101='" + frm.ID + "'")[0]["PUBLISH_DATE"] = frm.Publish_date;
dt.Select("I7101='" + frm.ID + "'")[0]["EFFECT_DATE"] = frm.EFFECT_DATE;
dt.Select("I7101='" + frm.ID + "'")[0]["USER_CODE"] = frm.UserCODE;
dt.Select("I7101='" + frm.ID + "'")[0]["MAKE_DATE"] = frm.Mark_Date;
dt.Select("I7101='" + frm.ID + "'")[0]["S_TYPE"] = "0";
}
else
{
try
{
DataRow _dr = dt.NewRow();
_dr["I7101"] = frm.ID;
_dr["AIRPORT_4CODE"] = frm.CODE;
_dr["PIC_CODE"] = frm.PIC_CODE;
_dr["PUBLISH_DATE"] = frm.Publish_date;
_dr["EFFECT_DATE"] = frm.EFFECT_DATE;
_dr["USER_CODE"] = frm.UserCODE;
_dr["MAKE_DATE"] = frm.Mark_Date;
_dr["S_TYPE"] = "0";
dt.Rows.Add(_dr);
}
catch (Exception)
{
MessageBox.Show("请您正确填写日期的格式");
}
}
gvImg.Refresh();
}
}

获取选中行指定列的值
注意： gcUSER_CODE 为需要获取的列，可根据实际需求改动
