ASP.NET实现增删改查等功能(Access版)系统之二-GridView绑定数据.

GridView绑定数据.

//绑定

public void bind(string str)

{

string oledbstr = "";

if (str != null && str != "")

{

oledbstr = str;

}

else

{

oledbstr = "select ID, 姓名,性别,出生日期,工作年限,证件类型,证件号,居住地,Email,手机号码,家庭电话,自我评价 from MResume order by id desc";

}

OleDbConnection oledbcon = new OleDbConnection(GetConnection());

OleDbDataAdapter myda = new OleDbDataAdapter(oledbstr, oledbcon);

DataSet myds = new DataSet();

oledbcon.Open();

myda.Fill(myds, "MResume");

GridView1.DataSource = myds.Tables[0]; //重点要记住的地方，看这个地方是DataSet or DataTable

GridView1.DataKeyNames = new string[] {"id"};//主键

GridView1.DataBind();

oledbcon.Close();

}

GridView行绑定

/// <summary>

/// 改变背景色,第二个方法

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

protected void GridView1_RowDataBound2(object sender, GridViewRowEventArgs e)

{

int i;

//执行循环，保证每条数据都可以更新

for (i = 0; i < GridView1.Rows.Count; i++)

{

//首先判断是否是数据行

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

{

//当鼠标停留时更改背景色

// e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");

//当鼠标移开时还原背景色

// e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

}

}

//如果是绑定数据行

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

{

//鼠标经过时，行背景色变 00A9FF E6F5FA

// e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#00A9FF'");

//鼠标移出时，行背景色变

// e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

}

//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)

{

//删除提示操作

((LinkButton)e.Row.Cells[13].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");

e.Row.Cells[11].Text = SubStr(e.Row.Cells[11].Text, 20); //用...代替长文本

}

}

//GridView实现自动编号：

if (e.Row.RowIndex != -1)

{

int id = e.Row.RowIndex + 1;

e.Row.Cells[0].Text = id.ToString();

}

//设置编辑状态文本框长度

//if ((e.Row.RowState == (DataControlRowState.Edit | DataControlRowState.Alternate)) || (e.Row.RowState == DataControlRowState.Edit))

//{

// TextBox curText;

// for (int j = 4; j < 12; j++)

// {

// curText = (TextBox)e.Row.Cells[j].Controls[0];

// curText.Width = Unit.Pixel(60); //设置长度

// curText.Font.Size = FontUnit.Point(11);//设置字号

// }

//}

}

public string SubStr(string sString, int nLeng)

{

if (sString.Length <= nLeng)

{

return sString;

}

string sNewStr = sString.Substring(0, nLeng);

sNewStr = sNewStr + "...";
