c# - 如何从 gridview 访问文本框文本到按钮 Onclick 事件

Question

我在 gridview 中有文本框和按钮。我想要的是，当我单击这些按钮时，文本框中的相应值会更新到数据库中，因此我需要在 OnClick 事件中访问文本框文本。我该怎么做？

GridView :

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            BackColor="#CCCCCC" BorderColor="#999999" 
            BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" 
            ForeColor="Black" OnRowDataBound="GridView1_RowDataBound" 
            onselectedindexchanged="GridView1_SelectedIndexChanged">
            <Columns>
                <asp:TemplateField HeaderText="Save 1">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" Width="30px" runat="server"></asp:TextBox>
                        <asp:Button ID="btnSave1" runat="server" Text="Save"  OnClick="btnSave1_Click" />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Save 2">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox2" Width="30px" runat="server"></asp:TextBox>
                        <asp:Button ID="btnSave2" runat="server" Text="Save"  OnClick="btnSave2_Click" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
</asp:GridView>

按钮点击事件:

protected void btnSave1_Click(object sender, EventArgs e)
    {
         //I want to access TextBox1 here.
    }

请帮我解决这个问题。

你可以这样做:

protected void btnSave1_Click(object sender, EventArgs e)
{
     GridViewRow row = (GridViewRow)((Button)sender).NamingContainer;
     TextBox TextBox1 = row.FindControl("TextBox1") as TextBox; 

      //Access TextBox1 here.
      string myString = TextBox1.Text;
}
