在GridView里加CheckBox是比较常见的情景,下面的代码是最简单的获取选择那些checked的行的信息,代码直接复制,配置好连接字符串和数据库表后可用.
.aspx:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
SortExpression="ID" />
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString1 %>"
SelectCommand="SELECT [ID], [Name] FROM [test1]"></asp:SqlDataSource>
</div>
</form>
</body>
.cs:
protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvr in GridView1.Rows)
{
CheckBox cb = (CheckBox)gr.FindControl("CheckBox1");
if (cb.Checked)
{
Response.Write(gr.Cells[0].Text);
Response.Write("</br>");
}
}
}
如果想加上全选功能,在.aspx加上以下代码:
<HeaderTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" onclick="javascript:SelectAll(this);" style="position: relative" />
</HeaderTemplate>
<script language="javascript">
function SelectAll(tempControl)
{
//将除头模板中的其它所有的CheckBox取反
var theBox=tempControl;
xState=theBox.checked;
elem=theBox.form.elements;
for(i=0;i<elem.length;i++)
if(elem[i].type=="checkbox" && elem[i].id!=theBox.id)
{
if(elem[i].checked!=xState)
elem[i].click();
}
}
</script>
以后会补上分页的情况.
