            <asp:CheckBox ID="CheckBox1" runat="server"/>
        </ItemTemplate>
</asp:TemplateField>

推荐答案

使用

<asp:checkbox id="CheckBox1" runat="server" oncheckedchanged="CheckBox1_CheckedChanged" xmlns:asp="#unknown" />

然后尝试

and then try

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
GridViewRow gr = (GridViewRow)chk.Parent.Parent;
lblmsg.Text = GridView1.DataKeys[gr.RowIndex].Value.ToString();

//lblmsg.Text = "Hello";
} 

也许会有所帮助.请参阅复选框部分

Maybe this will help. See the section on checkboxes

尝试一下，

在Gridview中修改复选框，例如，

Try this,

Modify Checkbox in Gridview like,

<asp:TemplateField HeaderText="View">
<ItemTemplate>
<asp:CheckBox ID="chkview" runat="server" AutoPostBack="true" OnCheckedChanged="chkview_CheckedChanged" />
</ItemTemplate>
</asp:TemplateField>

然后在代码"视图中定义，

And on Code view define,

protected void chkview_CheckedChanged(object sender, EventArgs e)
{
     //Define your code here.
}
