C# - Dynamically Add Rows To A Table?
Sep 24, 2010
So today I started learning ASP.NET. Unfortunately I haven't found any good tutorials online, and I can't afford to buy books at the moment, so I've had to create a ASP.NET web application in Visual Studio 2010 and just play around with the default project setup. So far here's what I have in my Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<!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>Project Management</title>
</head>
<body>
<div style="padding-bottom:10px;"> Project Management System</div>
<div> <table style="width:100%;">
<tr>
<td>Name</td>
<td>Task</td>
<td>Hours</td>
</tr>
</table></div>
</body>
</html>
I created a simple table with the header row already in there. Through a C# script, I want to be able to dynamically add rows to this HTML table. Is this the right way of thinking in ASP.NET? If so, how can I do this? I'm sure I'll need an "Add" button, which adds a new row to the table, with editable fields, and a "submit" button which adds some stuff to a database. Basically just a rundown of how this is done would be ever so helpful. Also if anyone knows any good tutorials or websites

Does anyone know how to dynamically add and remove rows in a table triggered by a button click from the backend (in c#) using asp.net?
Here's how it might be done in javascript, is there any way to do this in the asp.net framework?

Protected Sub btnAddRow7_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddRow7.Click
Dim tableRow As New System.Web.UI.WebControls.TableRow
Dim tableCell As New System.Web.UI.WebControls.TableCell
Dim textBox As New System.Web.UI.WebControls.TextBox
tableCell.Controls.Add(textBox)
tableRow.Cells.Add(tableCell)
tbl7.Rows.Add(tableRow)
End Sub
but it only adds one row dynamically. After the first addition, more clicks to the button will not add more rows.

I created dynamically a table with 3 rows not by using table tag. I need to find these rows in scripting, in button click, if any of these rows is empty then need to generate an alert message like enter current row.

I'm maintaining a dynamically generated table in ASP.NET, which allows users to move items up and down in the table. What this essentially does behind the scenes is just swaps around the 'sortorder' which the table is sorted by. I have checks to see if a row is the first/last column, and if so only display up/down (whatever's relevant). An issue has crept up now and I have no idea why. For some reason, most of the time (not all of the time strangely) the up and down buttons don't work. Using 'Up' as an example, the current record does get set to the 'above' rows sortorder, but the 'above' row doesn't take the below rows sort order. Now I've set my breakpoints throughout my code, and strangely everything gets set fine. It's just when I call SubmitChanges() to the LINQ data context, that it seems to put the wrong value into the database. Also what's strange is that I think that if you click it again, it actually works. But it doesn't work properly as the number is still out by a bit.
Here's my code:
if (Request.QueryString["dir"] != null) {
if (Request.QueryString["dir"] == "up") {
var currentrecordup = (from s in dc.InvoiceItems
where Request.QueryString["val"] == s.id.ToString()
select s).Single();
int valsortidup = (int)currentrecordup.sortorder;
var prevrecordup = (from s in dc.InvoiceItems
where s.sortorder < valsortidup
orderby s.sortorder descending select s).First();
int prevsortidup = (int)prevrecordup.sortorder; int tempval = valsortidup;
currentrecordup.sortorder = prevsortidup; prevrecordup.sortorder = tempval; }
else if (Request.QueryString["dir"] == "down") {
var currentrecorddown = (from s in dc.InvoiceItems
where Request.QueryString["val"] == s.id.ToString()
select s).Single(); int valsortiddown = (int)currentrecorddown.sortorder;
var nextrecorddown = (from s in dc.InvoiceItems where s.sortorder > valsortiddown
orderby s.sortorder ascending select s).First();
int nextsortiddown = (int)nextrecorddown.sortorder; int tempvaldown = valsortiddown;
currentrecorddown.sortorder = nextsortiddown; nextrecorddown.sortorder = tempvaldown;}
dc.SubmitChanges(); Response.Redirect("EditInvoice.aspx?id=" + Request.QueryString["id"]);
}
The sortorder column in my table is an int field that allows nulls.

In my webform, i have 3-4 textbox, on there textchange event i have to fetch data from database and put it on the form. I have taken another html table (with runat="server") below textbox and and in textchange event created a new <tr>, <td> and simply added contents in <td>, then finally added <tr> in the table. This is done in UpdatePanel.
When i enter something in textbox1 data is added in that table,that's fine. But when i enter something in 2nd textbox the previous data is overridden. My requirement is that if 2nd textbox's text changes than another row with appropiate data should be added, i.e., now two rows. Silimarly if 3rd ,4th textbox data changes then subsequently 3 or 4 rows should be displayed.

I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.

I've been searching for hours trying to figure this out. I understand that somehow I need to recreate the control in page_load. I think seeing the code will let us better understand what I'm trying to do.

I have an asp:Table and around the mid point of the table there is a DDL with values 2-5. What I want to do is add the selected amount of rows using AJAX right after the table row that has the DDL in it. I know how to dynamicly crate the rows, the info in the rows, and how to use AJAX to make things. Problem is I can not put the ContentTemplate tag inbetween the asp:TableRow which would mark the location I want the dynamic rows to start being added. I did some searching on here but most posts I find start with making the table from code and not the asp:Table tag

I am trying to delete or add rows in a table but since the table is in an update panel,upon deletion the row goes away and then comes back.I have tried using return false but it does not seem to work in IE or FF.
I am using the following code:
$(document).ready(function () {
$(.table).click (function ()}
(this).parent().remove();
[code]...
Basically I need a way to disable the postback.

I have two possible header rows for a DataTable that I build dynamically. Setting the value of a cell works fine. Adding the cell to a TableRow works fine. The problem comes in where I have to build a second possible header row that uses the same cell.
An example is below.
trHead1 = New TableRow
trHead2 = New TableRow
tcCalc = New TableCell
tcCalc.Text = "Rates"
trHead1.Cells.Add(tcCalc)
trHead2.Cells.Add(tcCalc)
As soon as I make the second row add the cell, the cell disappears from the first row. This really doesn't make sense to me but that seems to be the way it is. If there is a work around other than duplicating the lines;
tcCalc = New TableCell
tcCalc.Text = "Rates"

Im creating a table dynamically in my codebehind to display some statistics. The table is in a usercontrol. When the page first loads, its created and displayed correctly. If I do something that generates a postback, the table subsequently disappears, this is because its created inside a !IsPostback. How can i ensure that the table, once its been generated, stays visble on the page ? I dont want to generate it each time the page loads as it involves a lot of calculations on the database which will slow the pageload down.
