c# - 无法在 gridview 中访问 TextArea 中的文本

Question

<ItemTemplate>
<textarea ID="TextArea1" TextMode="multiline" runat="server" cols="20" name="S1" rows="2">         </textarea><br />
<asp:Button ID="Button1" runat="server" CommandName = "comment" Text = "Comment"/>
</ItemTemplate>

 SqlParameter par1 = new SqlParameter("@txt", SqlDbType.VarChar);
        par1.Direction = ParameterDirection.Input;
        par1.Value = Request.Form["TextArea1"];
        com.Parameters.Add(par1);

我无法在 gridview 中的 textArea 中获取文本。我只是无法从后面的代码访问它。

我想将 textArea 中的文本分配给一个变量，但我无法访问 textArea

有什么想法吗？

我有一个示例 gridview，它可能对您有所帮助。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand" 
AlternatingRowStyle-BackColor="#006699"  
    AlternatingRowStyle-ForeColor="#FFFFFF" onrowupdating="GridView1_RowUpdating">
<Columns >

<asp:BoundField HeaderText="Name" DataField="uname" />
<asp:BoundField HeaderText="Pass" DataField="upass"/>
<asp:TemplateField>
<HeaderTemplate>Active</HeaderTemplate>
<ItemTemplate >
<asp:TextBox ID="TextArea1" runat="server" TextMode="multiline" Text='<%#Eval("active")%>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
 <asp:ButtonField CommandName="comment" Text="comment" />
</Columns>
</asp:GridView>

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
  if (e.CommandName == "comment")
  {
    string uname = "";
    int index = Convert.ToInt32(e.CommandArgument);
    GridViewRow row = GridView1.Rows[index];
    TextBox txtbox1_val = (TextBox)row.FindControl("TextArea1");
    uname = Server.HtmlDecode(row.Cells[1].Text.ToString());
    //write code here
  }
}
