我想在每個文本框下方創建動態2文本框和2個下拉列表，並在按鈕單擊下拉列表中。 這是我正在使用的代碼，它創建了動態文本框和下拉列表，但是它以橫向方式創建控件。我希望以垂直方式創建動態控件，並將在文本框和下拉列表中進行創建。如何在asp.net中創建動態文本框下拉列表
<div id="dvContainer" runat="server">
<table align="center" cellpadding="0" cellspacing="0" width="90%">
<tr>
<td>
<table width="100%">
<tr>
<td align="center">Date</td>
<td>
<asp:TextBox ID="TextBox1" runat="server" Width="150px"> </asp:TextBox>
</td>
<td align="center">Time</td>
<td>
<asp:TextBox ID="TextBox2" runat="server" Width="150px"></asp:TextBox>
</td>
<td align="center">Godown</td>
<td>
<asp:DropDownList ID="DropDownList1" runat="server" Width="150px">
</asp:DropDownList>
</td>
</tr>
</table>
</td>
</tr>
<tr>
<td><table width="100%">
<tr>
<td align="center">Item</td>
<td align="center">QTY</td>
<td align="center">Unit</td>
<td align="center">Available</td>
<td align="center"></td>
</tr>
<tr>
<td align="center">
<asp:DropDownList ID="DropDownList2" runat="server" Width="150px">
</asp:DropDownList>
</td>
<td align="center">
<asp:TextBox ID="TextBox3" runat="server" Width="150px"></asp:TextBox>
</td>
<td align="center">
<asp:DropDownList ID="DropDownList3" runat="server" Width="150px">
</asp:DropDownList>
</td>
<td align="center">
<asp:TextBox ID="TextBox4" runat="server" Width="150px"></asp:TextBox>
</td>
<td align="center">
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
</td>
</tr>
</table></td>
</tr>
</table>
</div>
這是我正在使用CS頁
public partial class StockEntry : System.Web.UI.Page
{
protected System.Web.UI.WebControls.DropDownList Ddl_Item;
protected System.Web.UI.WebControls.TextBox Txt_Quantity;
protected System.Web.UI.WebControls.DropDownList Ddl_Unit;
protected System.Web.UI.WebControls.TextBox Txt_Available;
protected void Page_Load(object sender, EventArgs e)
{
}
int countTimes = 0;
protected void Button1_Click(object sender, EventArgs e)
{
if (ViewState["countTimes"] == null)
{
countTimes = 1;
}
else
{
countTimes = Convert.ToInt32(ViewState["countTimes"]);
}
for (int i = 0; i < countTimes; i++)
{
Ddl_Item = new DropDownList();
Ddl_Item.ID = "Ddl_Item" + i;
Ddl_Item.Width = 180 + i;
Txt_Quantity = new TextBox();
Txt_Quantity.ID = "Txt_Quantity" + i;
Txt_Quantity.Width = 180 + i;
Ddl_Unit = new DropDownList();
Ddl_Unit.ID = "Ddl_Unit" + i;
Ddl_Unit.Width = 180 + i;
Txt_Available = new TextBox();
Txt_Available.ID = "Txt_Available" + i;
Txt_Available.Width = 180 + i;
dvContainer.Controls.Add(Ddl_Item);
dvContainer.Controls.Add(Txt_Quantity);
dvContainer.Controls.Add(Ddl_Unit);
dvContainer.Controls.Add(Txt_Available);
}
countTimes = countTimes + 1;
ViewState.Add("countTimes", countTimes);
}
}
請描述，你的問題非常嚴重 – Marco
