My requirement is when user clicks Add button, the textbox value must be added to listbox. The following code works well
[Code]....
But i don't want the user to add same text multiple times. The listbox items(Text) must be unique.
Lets say I have a Table called: TableA
and values
TableA_ID CompanyID
1 1294
2 1265
3 1294
4 1246
5 1265
I need to get the last inserted row (TableA_ID) of EVERY Unique CompanyID
So output should be
TableA_ID CompanyID
3 1294 (the last row of this CompanyID)
4 1246 (the last row of this CompanyID)
5 1265 (the last row of this CompanyID)
I have a tag:
<asp:ListItem
CssClass="LabelCSS">Executive</asp:ListItem>
and I am getting the error message
Validation(ASP .Net):Attribute CssClass is not a valid attribute of element ListItem.
What attribute would I use for Css with ListItem?
I have an SQL database table like the following:
ID // Code // Shape
The ID is the integer identifier.
On one line the Code may be OX01 and shape Hexagon for example
Then the next line the code is still OX01 but the shape is Triangle.
What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.
I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.
I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.

And the error is: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. I have gone through many pages , and tried by making the AllowDbNull property making True and then different things.

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.

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>

</table></div>
</body>

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
