VS2005中GridView简单应用(CheckBox实现全选)

GridView是VS2005中對VS2003的DataGrid的增強替代控件

下面展示一下它的基本常見應用

效果圖如下：



[查詢]按鈕：查詢數據庫 ，顯示信息Table 並 綁定GridView

//查詢按鈕

protected void btnQue_Click(object sender, EventArgs e)

{

this.tableInfo.Visible = true;

SqlConnection sqlconn = new SqlConnection("server=localhost;database=db;uid=uid;pwd=pwd;");

sqlconn.Open();

SqlDataAdapter sda = new SqlDataAdapter("select * from table", sqlconn);

DataSet ds = new DataSet();

sda.Fill(ds);

this.grvInfo.DataSource = ds;

this.grvInfo.DataBind();

sda.Dispose();

ds.Dispose();

sqlconn.Close();

}

[全選]按鈕：

//全選

protected void btnAllCh_Click(object sender, EventArgs e)

{

foreach(GridViewRow currow in grvInfo.Rows)

{

((CheckBox)currow.Cells[0].Controls[1]).Checked = true;

}

}

類似的[取消全選]的編碼為：

// 取消全選

protected void btnNoCh_Click(object sender, EventArgs e)

{

foreach (GridViewRow currow in grvInfo.Rows)

{

((CheckBox)currow.Cells[0].Controls[1]).Checked = false;

}

}

[明細]按鈕：

該按鈕的操作，要寫在GridView ROW按鈕事件--- RowCommand

// GridView ROW按鈕事件 RowCommand

protected void grvInfo_RowCommand(object sender, GridViewCommandEventArgs e)

{

if(e.CommandName.Equals("mingxin"))

{

ImageButton lb = (ImageButton)e.CommandSource;

GridViewRow curgvr = (GridViewRow)lb.Parent.Parent;

string paraValue = curgvr.Cells[2].Text.ToString();

//RegisterClientScriptBlock("openmingxin", "<script language='javascript'>window.open(src='mingxin.aspx?pihao="+ paraValue+"','newwindow','');</script>");　　　　

ClientScript.RegisterClientScriptBlock(this.GetType(), "aa", "<script language='javascript'>alert("+paraValue +"');</script>");

}

}

[刪除]按鈕：

可以在HTML原始檔中加上

<asp:BoundField HeaderText="審核" />

<asp:TemplateField HeaderText="刪除">

<ItemStyle HorizontalAlign="Center" />

<ItemTemplate>

<asp:ImageButton runat="server" ImageUrl="~/image/del.JPG" ID="delid" CommandName="del" OnClientClick="return confirm('確實要刪除嗎？');" />

</ItemTemplate>

</asp:TemplateField>

同時也可以如[明細]按鈕在GridView ROW按鈕事件--- RowCommand 對[刪除]點擊按鈕的事件進行服務器端處理!

GridView中 样板列 加入 按钮

============================

前台：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowCommand="GridView1_RowCommand" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">

<Columns>

<asp:BoundField DataField="personName" />

<asp:BoundField DataField="personAge" />

<asp:TemplateField HeaderText="操作">

<ItemTemplate>

<asp:Button ID="btn_OK" runat="server" Text="确定"

CommandArgument='<%# Eval("personName") %>' CommandName="btn_OK" />

<asp:Button ID="btn_Cancel" runat="server" Text="取消" CommandName="btn_Cancel"

CommandArgument='<%# Eval("personName") %>' />

</ItemTemplate>

</asp:TemplateField>

</Columns>

</asp:GridView>

后台：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)

{

//直接利用参数

string strName = e.CommandArgument.ToString();

//一种取得当前行的方法

GridViewRow currRow = (GridViewRow)((Button)e.CommandSource).Parent.Parent;

string strAge = currRow.Cells[1].Text.ToString();

if (e.CommandName == "btn_OK")

{

this.TextBox1.Text = "确定按钮 " + strName + " " + strAge;

}

if (e.CommandName == "btn_Cancel")

{

this.TextBox1.Text = "取消按钮 " + strName + " " + strAge;

}

}
