I have a website which uses the latest AJAX Control toolkit. On my pc, the website is loading perfectly well. The page makes use of a tab control and an update Panel - AJAX Control toolkit.Unfortunately when I uploaded the website online, on the shared web server, the website gives the following 3 errors (on IE) :
1) ASP.NET Ajax client-side framework failed to load
2) 'Sys' is unidentified
3) 'Sys' is unidentified
The page finally loads, however the ASP.NET Ajax controls do not load (Tab controls and UpdatePanel). The rest of the page loads perfectly well. I made some searches online, however still cant find a solution.
Facts:1. The site contains an Ajax Script Manager Proxy2. The web.config states that the site is not in debugging mode3. Tried to create a fresh new virtual directory and problem still persists. 4. On my Development machine the website is 100% functional.
I have an .aspx page with a gridview and a details view for looking up products. It is working perfectly. When I select "Details" on the gridview the details view accurately populates.I added an image named TagImageand need that image to display the correct one based upon the product changed when "Details" is hit. I'm using code behind and have checked my image directory string to make sure it is OK but the images do not display. Here is the vb.net code hehind I am using that successfully populates the details and was hoing it to display the picture:
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
AccessDataSource2.SelectParameters("ProdID").DefaultValue = _
GridView1.SelectedDataKey.Value.ToString()

this error is raised in the repeater databind event.

Having a bit of trouble with a logon page I created using text boxes for a User ID number and a password.
Basically, my original design was to have a textbox for a username and one for a password. Due to some complications, I changed the username to the User ID number input and as such, the input credentials went from being a string to an integer. I've changed this successfully, however when I now type in a string, rather than the integer it requires, the page fails.
how to edit this so if a user enters a string value instead of a numeric value, an error message can show up on a label instead of the whole project coming to a halt because of an error?
Here's the code I have for the page so far, which does the job (apart from this problem!)
using System;
using System.Data;
using System.Data.Sql;
using System.Data.SqlClient;

I'm quite new to ASP.NET and i was wondering if someone could answer some of my questions.1. What is the difference between a DataTable and an Array? Is the DataTable a serverside control? Is it exposed to the user?2. Does the reader retrieve the column names? If so- how can I capture them? Are they the first row?2. Is it possible to populate an Array using the following sort of code, and if so- how?:
SqlCommand tableCommand = new SqlCommand();
SqlConnection tableConnection = new SqlConnection();
tableCommand.Connection = tableConnection;

Here is what I have tried:
txtCost.Text = string.Format("{o:c}", dr["Cost"]);
Here is the error I receive. How can I format the data that is coming from the data reader into currency format??? Also, is there a way to format it into currency without the dollar sign?
Input string was not in a correct format. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.

I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?

I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?

However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
