Web Forms :: Adding Table Rows Dynamically Only Works First Time?

Jan 13, 2010

Forms Data Controls :: Dynamically Adding Rows To A Table

Apr 19, 2010

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.

AJAX :: Adding Table Rows At Specific Point In Table?

Dec 23, 2010

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

Counting Rows In C# After Dynamically Adding Them With JQuery

Dec 15, 2010

I just have a simple ASP Table seen here:

<asp:Table ID="tblCategories" runat="server" CssClass="oneColTable padded-table dataTable">
<asp:TableHeaderRow CssClass="tableHeader">
<asp:TableHeaderCell>Category Name</asp:TableHeaderCell>
<asp:TableHeaderCell Width="50">Delete</asp:TableHeaderCell>

And if the user wants to add an additional row I use the jQuery Clone method to copy and append a new row.

My issue comes when I want to count the rows present on the C# side it always lists 1 Row. The row for the header entry.

How can I correctly grab the accurate row count on the C# (Codebehind) side?

C# - Dynamic Adding Rows Into Table?

How can I add rows in a table from server-side?

if (!Page.IsPostBack)
Session["table"] = TableId;
TableId = (Table)Session["table"];
protected void btnAddinRow_Click(object sender, EventArgs e)
num_row = (TableId.Rows).Count;
TableRow r = new TableRow();
TableCell c1 = new TableCell();
TableCell c2 = new TableCell();
TextBox t = new TextBox();
t.ID = "textID" + num_row;

c1.ID = "newC1" + num_row;
c2.ID = "newC2" + num_row;

in debug I found out the number in the "TableID", but the rows are not drawn. Have you got an idea about this issue?

Web Forms :: Dynamically Adding Controls To A Table Across Multiple Functions?

Mar 13, 2010

I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.

When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.

In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.

I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?

My current code which doesnt work:

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>
<div style="padding-bottom:10px;"> Project Management System</div>
<div> <table style="width:100%;">

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

C# - Adding Rows To A Table Based On User Input?

Jan 19, 2010

I have a TextBox entry field where the user will enter a integer value. And then there is a "Create" button, which when clicked upon must generate a Table with 2 columns :

"Name" and "Email" being the column headers.

I want each row to have a textbox in each of these columns.

All of this has to happen after the button is clicked. I have discovered that if you dynamically add a control in ASP.NET(I am using C#) then the controls are lost during postback. And I don't know how to prevent that from happening.

Can somebody give me some ideas regarding how to go about adding rows dynamically to a table (I tried using the asp.net Server side table control but ran into the "lost-during-postback" problem - can I try with something else like a gridview ? but afaik a GV will not work without data bound to it )

Point to note is that my table has textboxes for user entry and it is not for showing data ..rather it is for accepting data from the user which will be later used to persist details to the database.
