数据列表就像这样

datalist is like this

<asp:DataList ID="DataList1" runat="server" OnItemCommand="DataList1_ItemCommand">
                        <HeaderTemplate>
                            Roleid Rolename description
                        </HeaderTemplate>
                        <ItemTemplate>
                            <table width="100%">
                                <tr>
                                    <td>
                                        <asp:Label ID="lblid11" runat="server" Text='<%#Eval("ROLE_ID") %>' />
                                    </td>
                                    <td>
                                        <asp:Label ID="lblid12" runat="server" Text='<%#Eval("ROLE_NAME") %>' />
                                    </td>
                                    <td>
                                        <asp:Label ID="lblid13" runat="server" Text='<%#Eval("DESCRIPTION") %>' />
                                    </td>
                                    <td>
                                        <asp:Button ID="btninside" runat="server" CommandName="call" Text="click me" />
                                    </td>
                                </tr>
                            </table>
                        </ItemTemplate>

                    </asp:DataList>

在按钮中单击是否需要标签数据(标签在数据列表中)
如果此按钮在数据列表之外
您可以像这样获取标签文字

in button click if you want the label data (label is inside the datalist)
if this button is outside the datalist
you can get the label text like this

<asp:button id="btntest" runat="server" text="Test" onclick="btntest_Click" xmlns:asp="#unknown" />

protected void btntest_Click(object sender, EventArgs e)
    {

        foreach (DataListItem item in DataList1.Items)
        {
            lblm.Text += "," + ((Label)(item.FindControl("lblid11"))).Text;
        }
    }

如果您的按钮在数据列表中，则可以这样访问

if your button is inside the datalist you can access like this

 protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "call")
 {
 DataListItem item=(DataListItem)(((Button) (e.CommandSource)).NamingContainer);
 string text = ((Label)item.FindControl("lblid12")).Text;
}
}
