Menu
I am using asp.net [ c# ] ..
My question is about adding new row; if I click on that button (like every time I click on that button it will add new row) .. I thought its easy to do it .. but it is not there. Something is missing I don't know what.
My code is [ Default3.aspx ] :
<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<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>
and for my 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);
}
I don't know what the problem is .. I even give each controls an IDs .. and I tried other ways but didn't work ..
Please if anyone can help me out .. I feel like am missing something important but I don't know what it is ..

As given in the Question shared in Walid's answer, follow these steps:
Create a global list of table rows, something like:
List<TableRow> TableRows
In button click Add the newly created row to list:
TableRow row1=new TableRow();
TableRows.add(row1);
In the OnInit method simply add all the rows to the table:
foreach ( TableRow row in TableRows )
{
Table1.Rows.Add(row);
}
It will solve your problem.
