C＃如何在GridView上创建Hyperlink事件？ [英] C# How do I create a Hyperlink OnClick event on GridView?

问题描述

我无法创建我想要的GridView。
我希望用户进入该网站并查看连接到数据库的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）到数据库中。

I'm having trouble creating the GridView I want. I would like the user to get inside the website and see the GridView which is attached to a DB. Columns are: ID, InsertionTime, Filepath, ProccessedByUser Now I want the user to click the filepath he/she would like to process. When he/she clicks the filepath, I want their username (logged in with built-in asp website authentication) to be updated (added) into DB.

我的标记是标准和我没有管理后面的代码。

My markup is standard and I haven't got to manage with code behind.

<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。

I tried using HyperlinkField but it doesn't seem to support onlick events.

有什么建议吗？
Thanks。

Any suggestions? Thanks.

推荐答案

我假设您正在寻找 LinkBut​​ton 控件，其中包含 OnClick 事件。

I assume you are looking for the LinkButton control which has an OnClick event.

<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 LinkBut​​ton的 点击事件或 GridView的 RowCommand 事件。

Now you can handle the LinkButton's click event or the GridView's RowCommand event.

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，我使用 TemplateField 这是 GridView 中最具动态的列类型，因为您可以添加任何你想要的，甚至嵌套的GridViews或 UserControls 。

Note that i've used a TemplateField which is the most dynamic column type in a GridView since you can add anything you want, even nested GridViews or UserControls.
