Question

I have a ListView that creates a table. Each row in the table has two buttons – Delete and Modify. I’m firing a click event for each button but I’m not sure how to get a handle to the data in the row that the button was clicked.

aspx

<asp:ListView runat="server" ID="usersListView">
    <LayoutTemplate>
        <table class="table table-striped">
            <thead>
                <tr>
                    <th>User Name</th>
                    <th>Email</th>
                    <th>Role</th>
                    <th>Actions</th>
                </tr>
            </thead>
            <tbody>
                <asp:PlaceHolder runat="server" ID="groupPlaceHolder"/>
            </tbody>
        </table>
    </LayoutTemplate>
    <GroupTemplate>
        <tr>
            <asp:PlaceHolder runat="server" ID="itemPlaceHolder"/>
        </tr>
    </GroupTemplate>
    <ItemTemplate>
        <td><%# Eval("user.UserName") %></td>
        <td><%# Eval("user.Email") %></td>
        <td><%# Eval("roles") %></td>
        <td>
            <button runat="server" id="modify" class="btn btn-mini" title="Modify" onclick="modify_OnClick">
                <i class="icon-edit"></i>
            </button>&nbsp;
            <button runat="server" id="delete" class="btn btn-mini" title="Delete" onclick="delete_OnClick">
                <i class="icon-trash"></i>
            </button>
        </td>
    </ItemTemplate>
</asp:ListView>

aspx.cs

public void delete_Onclick(object sender, EventArgs e) {

}

public void modify_Onclick(object sender, EventArgs e) {

}

I will try to answer the question in the title since i don’t understand the question itself.

You can cast the the sender to the Button. The Button’s NamingContainer is the ListViewItem. You can use this to get all your other control in that item by using item.FindControl("OtherControlID").

For example;

public void delete_Onclick(object sender, EventArgs e) {
    var btn = (Button)sender;
    var item = (ListViewItem)btn.NamingContainer;
    // find other controls:
    var btnModify = (Button)item.FindControl("modify");
}

You cannot find text that is not in a server control. But you could use a LiteralControl or Label to display the username or email.

<td><asp:Label id="Label1" runat="server"
          Text='<%# Eval("user.UserName") %>' />
</td> 

Now you can use FindControl as shown above to get a reference to the label in codebehind.
