ASP.NET + GridView控件+ EmptyDataTemplate [英] ASP.NET + GridView + EmptyDataTemplate

问题描述

我有一个使用EmptyDataTemplate一个ASP.NET的GridView。此模板用于收集事件没有记录在我的数据源中存在的数据。我的GridView控件来源是这样的：

I have an ASP.NET GridView that uses an EmptyDataTemplate. This template is used to collect data in the event that no records exist in my data source. My GridView source looks like this:

<asp:GridView ID="myGridView" runat="server" 
  DataKeyNames="ID" OnRowEditing="myGridView_RowEditing" 
  OnRowCancelingEdit="myGridView_RowCancelingEdit"   
  OnRowUpdating="myGridView_RowUpdating"                            
  ShowFooter="True" EnableModelValidation="True">
  <Columns>
    <asp:BoundField DataField="ID" Visible="false" />
    <asp:TemplateField HeaderText="Name">
      <EditItemTemplate>
        <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
      </EditItemTemplate>
      <ItemTemplate>
        <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
      </ItemTemplate>
      <FooterTemplate>
        <asp:TextBox ID="nameFooterTextBox" runat="server" />
      </FooterTemplate>
    </asp:TemplateField>
    <asp:TemplateField HeaderText="Age">
    <EditItemTemplate>
      <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("Age") %>' />
    </EditItemTemplate>
    <ItemTemplate>
      <asp:Label ID="Label2" runat="server" Text='<%# Bind("Age") %>' />
    </ItemTemplate>
    <FooterTemplate>
      <asp:TextBox ID="ageTextBox" runat="server" />
    </FooterTemplate>
  </asp:TemplateField>
  <asp:CommandField HeaderText="Options" HeaderStyle-HorizontalAlign="Left" 
    ButtonType="Link" ShowEditButton="true" ShowDeleteButton="true" >
  </asp:CommandField>
</Columns>

<EmptyDataTemplate>
  <table border="0" cellpadding="0" cellspacing="0">
    <tr>
      <td>Name</td>
      <td>Age</td>
      <td>Options</td>
    </tr>
    <tr>
      <td><asp:TextBox ID="nameTextBox" runat="server" /></td>
      <td><asp:TextBox ID="ageTextBox" runat="server" /></td>
      <td><asp:LinkButton ID="saveLinkButton" runat="server" Text="save" OnClick="saveLinkButton_Click" /></td> 
    </tr>
  </table>
</EmptyDataTemplate>

当用户点击了EmptyDataTemplate了saveLinkBut​​ton，我想从文本框的值，并插入一个新的记录进入我的数据源。我的问题是，如何获取这些文本字段的值当有人点击saveLinkBut​​ton？

When a user clicks the "saveLinkButton" in the EmptyDataTemplate, I want to get the values from the TextBoxes and insert a new record into my data source. My question is, how do I get the values of those text fields when somebody clicks the "saveLinkButton"?

感谢您！

推荐答案

这将线在在asp.net提出了一个解决这个问题（注：我还没有尝试过了）

This thread over at asp.net proposes a solution to this problem (Note: I haven't tried it out)

您需要处理RowCommand事件，获取引发事件的控制（你的LinkBut​​ton）的父命名容器，然后搜索内使用的FindControl文本框。

You need to handle the RowCommand event, get the parent naming container of the control that raise the event (your linkbutton) and then search for the textboxes using FindControl within that.
