[ASP.NET]GridView触发SelectedIndexChanged事件

 

首先在GridView中必须加上“选择”的按钮，然后在Page_Load中添加

protected void Page_Load(object sender, EventArgs e)
{
gvTest.SelectedIndexChanged+=new EventHandler(GridView1_SelectedIndexChanged);
}

protected void Page_Load(object sender, EventArgs e) { gvTest.SelectedIndexChanged+=new EventHandler(GridView1_SelectedIndexChanged); }

最后在点击绑定的GridView项的时候就可以触发SelectedIndexChanged事件了。

这里我把“选择”按钮设置成了TemplateField，然后让它的Text绑定Email字段，数据库的其余字段也可以绑定到GridView上，但是在这个程序里我把他们的可见属性都设置成了False。

页面代码：

"form1" runat="server">
"overflow-y: auto; width: 100%; height: 100%">
"gvTest" runat="server" AutoGenerateColumns="False"
DataKeyNames="UserId" DataSourceID="SqlDataSource1" ShowHeader ="false">

"UserId" HeaderText="UserId" InsertVisible="False"
ReadOnly="True" SortExpression="UserId" Visible="False" />
"EMail" HeaderText="EMail" SortExpression="EMail"
Visible="False" />
"Passwd" HeaderText="Passwd" SortExpression="Passwd"
Visible="False" />
"LastLogin" HeaderText="LastLogin"
SortExpression="LastLogin" Visible="False" />
"False">

"LinkButton1" runat="server" CausesValidation="False"
CommandName="Select" Text='<%# Bind("EMail", "{0}") %>'>






"lblRegionCaption" runat="server" Text="Label">

"SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:vMessageCenterConnectionString %>"
SelectCommand="SELECT [UserId], [EMail], [Passwd], [LastLogin] FROM [Users]">

在页面中加入了垂直滚动条。

SelectIndexChenged事件的代码：

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
int index = GridView1.SelectedIndex;
string ID = GridView1.SelectedDataKey.Values["UserId"].ToString();
lblRegionCaption.Text = ID;
GridViewRow row = GridView1.SelectedRow;
}
