gridveiw操作大全
本文操作数据库使用的是OracleHelp类实现的。参见PetShop
1 gridview的绑定
调用如下：
String ziDianMingChenSql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
ziDianMingChenGrid(ziDianMingChenSql);
/// <summary>
/// 填充GridView
/// </summary>
private void ziDianMingChenGrid(String querySql)
{
DataSet ds = new DataSet();
ds = GetData(querySql);
// 清空以前的数据源
GridViewZiDianMingChen.DataSource = null;
// 将ds作为信息栏GridView的数据源
GridViewZiDianMingChen.DataSource = ds;
// 绑定数据
GridViewZiDianMingChen.DataBind();
// 保存数据源 防止丢失 VS的破Bug
ViewState["GridViewZiDianMingChen_DataSource"] = GridViewZiDianMingChen.DataSource;
// 保存SQL语句
ViewState["sqlGridViewZiDianMingChen"] = querySql;
}
/// <summary>
/// 转换SQL查询结果为DataSet
/// </summary>
/// <returns>ds</returns>
private DataSet GetData(String querySql)
{
String connStr = OracleHelper.DatabaseConnStr;
// 创建数据集
DataSet ds = OracleHelper.ExeSqlForDataSet(connStr, CommandType.Text, querySql, null);
return ds;
}
2 gridview 换行控制
this.GridViewZiDianMingChen.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");
this.GridViewXinXiLan.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");
3 编辑
/// <summary>
/// 编辑
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridViewZiDianMingChen_RowEditing(object sender, GridViewEditEventArgs e)
{
GridViewZiDianMingChen.EditIndex = e.NewEditIndex;
String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
ziDianMingChenGrid(querySql);
}
4 取消
/// <summary>
/// 取消

/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridViewZiDianMingChen_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{

String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
ziDianMingChenGrid(querySql);
}
5 更新
/// <summary>
/// 更新
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridViewZiDianMingChen_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string sn = GridViewZiDianMingChen.DataKeys[e.RowIndex].Values[0].ToString().Trim();
String delXinWenSql = "UPDATE zidianmingcheng SET 字典名称 = '" + ((TextBox)(GridViewZiDianMingChen.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "' WHERE SN = '" + sn + "'";
OracleConnection conn = new OracleConnection(OracleHelper.DatabaseConnStr);
conn.Open();
OracleTransaction trans = conn.BeginTransaction(IsolationLevel.ReadCommitted);
try
{
OracleHelper.ExecuteNonQuery(trans, CommandType.Text, delXinWenSql, null);
trans.Commit();
}
catch (Exception ex)
{
trans.Rollback();
ex.ToString();
}
finally
{
conn.Close();
}
GridViewZiDianMingChen.EditIndex = -1;
String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
ziDianMingChenGrid(querySql);
}
6 删除
/// <summary>
/// 删除字典项
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridViewXinXiLan_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
String sn = GridViewXinXiLan.DataKeys[e.RowIndex].Values[0].ToString().Trim();
String delSql = "DELETE FROM xitongzidian WHERE SN = '" + sn + "'";
OracleConnection conn = new OracleConnection(OracleHelper.DatabaseConnStr);
conn.Open();
OracleTransaction trans = conn.BeginTransaction(IsolationLevel.ReadCommitted);
try
{
OracleHelper.ExecuteNonQuery(trans, CommandType.Text, delSql, null);
trans.Commit();
}
catch (Exception ex)
{
trans.Rollback();
ex.ToString();
}
finally
{
conn.Close();
}
GridViewXinXiLan.EditIndex = -1;
String ziDianBianHao = this.GridViewZiDianMingChen.Rows[this.GridViewZiDianMingChen.SelectedRow.RowIndex].Cells[2].Text.ToString().Trim();
String querySql = "SELECT 序号,名称,SN FROM xitongzidian WHERE ID='" + ziDianBianHao + "'";
fillGridView(querySql);
}
7 删除弹出对话框
/// <summary>
/// 实现删除弹出对话框
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridViewXinXiLan_RowDataBound(object sender, GridViewRowEventArgs e)
{
//如果是绑定数据行
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
{
((LinkButton)e.Row.Cells[4].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
}
}
}
上面的代码如果一列中有2个控件会报错.用下面的即可.
//如果是绑定数据行
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
{
//((LinkButton)e.Row.Cells[12].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
((LinkButton)e.Row.FindControl("LinkButton3")).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
}
}
运行图如下：
图2: 点击选择按钮后显示另一个gridview。
3 编辑左边的gridview。可以设置字典编号为只读而使得其不可编辑
4 点击右边的删除按钮
5 点击右边的新增按钮

<div style="overflow: scroll; height: 300px">
<asp:GridView ID="GridViewZiDianMingChen" runat="server" AutoGenerateColumns="False"
CellPadding="4" ForeColor="#333333" PageSize="1" EmptyDataText=" " OnRowCancelingEdit="GridViewZiDianMingChen_RowCancelingEdit" OnRowEditing="GridViewZiDianMingChen_RowEditing" OnRowUpdating="GridViewZiDianMingChen_RowUpdating" DataKeyNames="SN" OnSelectedIndexChanged="GridViewZiDianMingChen_SelectedIndexChanged1" Height="5px">
.........
</asp:GridView>
</div>
效果图:(其中的GirdLines设置为Both)好象好看点.
7 空数据时显示表头
<EmptyDataTemplate>
序号 名称
</EmptyDataTemplate>
8 添加一行空行
DataTable dt = new DataTable();
DataRow row = dt.NewRow();
dt.Columns.Add("建立日期", typeof(string));
dt.Columns.Add("姓名", typeof(string));
dt.Columns.Add("类型", typeof(string));
dt.Columns.Add("名称", typeof(string));
dt.Columns.Add("开始时间", typeof(string));
dt.Columns.Add("结束时间", typeof(string));
dt.Columns.Add("取得证书", typeof(string));
dt.Columns.Add("备注", typeof(string));
dt.Columns.Add("经办人", typeof(string));
dt.Columns.Add("SN", typeof(string));
row[0] = "2006-6-18";
row[1] = "张三";
row[2] = "培训";
row[3] = "干部培训";
row[4] = "2006-6-18";
row[5] = "2006-6-18";
row[6] = "资格证书";
row[7] = "无";
row[8] = "王二";
row[9] = "234234234";
dt.Rows.Add(row);
// 清空以前的数据源
GridViewTianJia.DataSource = null;
// 将ds作为信息栏GridView的数据源
GridViewTianJia.DataSource = dt;
// 绑定数据
GridViewTianJia.DataBind();
本来有个更好的,不知道怎么写了现在 郁闷!
9 隐藏一列
GridViewTianJia.Columns[10].Visible = false;
10 隐藏单元
GridViewTianJia.Rows[0].Cells[10].Visible = false;
11 与dropdownlist的结合
