我正在使用 asp.net [ c# ] ..
我的问题是关于添加新行;如果我单击该按钮(就像每次单击该按钮时它都会添加新行)..我认为它很容易做到..但它不存在。有什么东西不见了,我不知道是什么。
我的代码是 [ Default3.aspx ]:
<%@ Page Language="C#" AutoEventWireup="true"

<form id="form1" runat="server">
<div align="center">
<asp:Table ID="Table1" runat="server">
<asp:TableRow>
<asp:TableCell style="border-style:solid" >
<asp:Label ID="Label1" runat="server" Text="LABEL = 1 ">
</asp:Label>
</asp:TableCell>
<asp:TableCell style="border-style:solid" >
<asp:Label ID="Label2" runat="server" Text="LABEL = 2 ">
</asp:Label>
</asp:TableCell>
</asp:TableRow>
<asp:TableRow>
<asp:TableCell style="border-style:solid" >
<asp:Label ID="Label3" runat="server" Text="LABEL = 3 ">
</asp:Label>
</asp:TableCell>
<asp:TableCell style="border-style:solid" >
<asp:Label ID="Label4" runat="server" Text="LABEL = 4 ">
</asp:Label>
</asp:TableCell>
</asp:TableRow>
</asp:Table>
<asp:Button ID="Button1" runat="server" Text="Add More"
onclick="Button1_Click" />
</div>
</form>
</body>
</html>
对于我的 C# [ Default3.aspx.cs ] :
protected void Button1_Click(object sender, EventArgs e)
{
TableRow NewRow1 = new TableRow();
//1st cell
TableCell NewCell1 = new TableCell();
NewCell1.Style.Add("border-style","solid");
// new lebel
Label newLable1 = new Label();
count = count + 1; // just for change number in label text
newLable1.Text = "NewLabel = "+ count;
// adding lebel into cell
NewCell1.Controls.Add(newLable1);
// adding cells to row
NewRow1.Cells.Add(NewCell1);
//2ed cell
TableCell NewCell2 = new TableCell();
NewCell2.Style.Add("border-style", "solid");
Label newLable2 = new Label();
count = count + 1;
newLable2.Text = "NewLabel = " + count;
NewCell2.Controls.Add(newLable2);
NewRow1.Cells.Add(NewCell2);
//adding row into table
Table1.Rows.Add(NewRow1);
}
我不知道问题是什么..我什至给每个控件一个ID..我尝试了其他方法但没有奏效..
请如果有人可以帮助我..我觉得错过了一些重要的东西,但我不知道它是什么..
