C#如何在GridView上创建Hyperlink OnClick事件？

Question

我在创建我想要的GridView时遇到了麻烦.我希望用户进入网站,看到附加到数据库的GridView.列是:ID, InsertionTime, Filepath, ProccessedByUser 现在我希望用户单击他/她想要处理的文件路径.当他/她单击文件路径时,我希望将他们的用户名(使用内置的asp网站身份验证登录)更新(添加)到DB中.

我的标记是标准的,我无需管理代码.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="ID" DataSourceID="AccessDataSource1" 
    onselectedindexchanged="GridView1_SelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" 
            ReadOnly="True" SortExpression="ID" />
        <asp:BoundField DataField="starttime" HeaderText="starttime" 
            SortExpression="starttime" />
        <asp:HyperLinkField DataNavigateUrlFields="path" DataTextField="path" 
            HeaderText="path" />
        <asp:BoundField DataField="user" HeaderText="user" SortExpression="user" />
    </Columns>
</asp:GridView>

我尝试使用HyperlinkField,但它似乎不支持onlick事件.

有什么建议？谢谢.

我假设您正在寻找LinkButton具有OnClick事件的控件.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="ID" DataSourceID="AccessDataSource1" 
    onselectedindexchanged="GridView1_SelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" 
            ReadOnly="True" SortExpression="ID" />
        <asp:BoundField DataField="starttime" HeaderText="starttime" 
            SortExpression="starttime" />
        <asp:TemplateField HeaderText="Path" SortExpression="Filepath">
            <ItemTemplate>
                <asp:LinkButton ID="LbPath" runat="server" 
                    Text='<%# Eval("Filepath") %>'
                    CommandName="PathUpdate" 
                    CommandArgument='<%#Bind("path") %>'>
                </asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="user" HeaderText="user" SortExpression="user" />
    </Columns>
</asp:GridView>

现在您可以处理LinkButton's click事件或GridView's RowCommand事件.

protected void Gridview1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "PathUpdate")
    {
        string path= e.CommandArgument.ToString();
        // do you what you need to do
    }
}

请注意,我已经使用了a TemplateField中最动态的列类型,GridView因为您可以添加任何您想要的内容,甚至是嵌套的GridViews或UserControls.
