asp.net中DataGridView的常用用法

　　DataGridView的常用用法 //读取表Supplier并绑定到GridView中

　　private void BindGvSupplier()

　　...{

　　OracleConnection conn = this.Conn();

　　OracleCommand cmd = new OracleCommand( "select * from Supplier ", conn);

　　OracleDataAdapter sda = new OracleDataAdapter(cmd);

　　DataSet ds = new DataSet();

　　sda.Fill(ds, "Supplier ");

　　string[] SuppId = new string[ds.Tables[ "Supplier "].Rows.Count];

　　for (int i = 0; i <ds.Tables[ "Supplier "].Rows.Count; i++)

　　...{

　　SuppId[i] = ds.Tables[ "Supplier "].Rows[i][0].ToString();

　　}

　　this.gvSupplier.DataSource = ds.Tables[ "Supplier "];

　　this.gvSupplier.DataKeyNames[0] = "SuppId ";

　　this.gvSupplier.DataBind();

　　this.lblPageIndex.Text = Convert.ToString(int.Parse(this.gvSupplier.PageIndex.ToString()) + 1);

　　this.lblTotalPage.Text = this.gvSupplier.PageCount.ToString();

　　this.lblCount.Text = this.GetTotalCount().ToString();

　　}

　　//分页触发的事件

　　protected void gvSupplier_PageIndexChanging(object sender, GridViewPageEventArgs e)

　　...{

　　this.gvSupplier.PageIndex = e.NewPageIndex;

　　this.BindGvSupplier();

　　this.lblPageIndex.Text = Convert.ToString(int.Parse(this.gvSupplier.PageIndex.ToString()) + 1);

　　this.cbAllSelect_CheckedChanged(this.cbAllSelect, e);

　　}

　　//删除按钮触发的事件

　　protected void gvSupplier_RowDeleting(object sender, GridViewDeleteEventArgs e)

　　...{

　　int id = e.RowIndex;

　　GridViewRow gvr = this.gvSupplier.Rows[id];

　　int SuppId=int.Parse(((HyperLink)(gvr.Cells[7].Controls[0])).Text.ToString());

　　string sqlString = "delete from Supplier where SuppId= " + SuppId;

　　//如果本页只有一条数据，删除后要向前翻一页

　　if (this.gvSupplier.Rows.Count == 1)

　　...{

　　if (this.gvSupplier.PageIndex >1)

　　...{

　　this.gvSupplier.PageIndex--;

　　}

　　}

　　int result = ExecuteSql(sqlString);

　　if (result == 1)

　　...{

　　this.Alert( "你成功删除一条数据 ", this.Page);

　　}

　　this.BindGvSupplier();

　　this.BindGvSupplier();

　　}

　　//绑定删除按钮的确认提示

　　protected void gvSupplier_RowDataBound(object sender, GridViewRowEventArgs e)

　　...{

　　if (e.Row.RowType == DataControlRowType.DataRow)

　　...{

　　LinkButton myLb = (LinkButton)(e.Row.Cells[8].Controls[1]);

　　myLb.Attributes.Add( "onclick ", "javascript:return confirm( &apos;你确认删除 "+e.Row.Cells[0].Text+ "吗? &apos;) ");

　　//鼠标经过时改变行的颜色

　　e.Row.Attributes.Add( "onmouseover ", "this.style.backgroundColor= &apos;#ffffe7 &apos; ");

　　e.Row.Attributes.Add( "onmouseout ", "this.style.backgroundColor= &apos;transparent &apos; ");

　　}

　　}

　　//执行一条Oracle语句

　　private int ExecuteSql(String sqlString)

　　...{

　　//try

　　//{

　　OracleConnection conn = this.Conn();

　　conn.Open();

　　OracleCommand cmd = new OracleCommand(sqlString, conn);

　　int effectedLine = cmd.ExecuteNonQuery();

　　conn.Close();

　　return effectedLine;

　　//}

　　//catch

　　//{

　　// return 0;

　　//}

　　}
