I have two text boxes that should be getting filled with Ajax AutoCompleteExtender information. One text done with a Web Service and the other is a code behind Web Method. The Web Service one is for Customer IDs; If I start my page with the web service and put in a number for the ID it works and gives me all of the information but if I try to do it in my actual asp.net form then nothing happens when I type in a number to for my search criteria. Also, for the Web Method from the code behind doesn't seem to find anything for me when I type a letter...... I'm wondering if I am missing a reference or something that is making my actual web page not fetch the data or am I just doing it wrong as this is my first time using this.
I am using Visual Studio 2012

I think your problem is with your method signature. If you have UseContextKey="True", the method should be:
public static string[] GetCustomerID(string prefixText, int count, string contextKey)
{
}
If UseContextKey="False", the method should be:
public static string[] GetCustomerID(string prefixText, int count)
{
}

I try to add data from a form to one of my SQL Server database table. I was reading all the materials on stack but it seems I am doing something wrong I can't see.

I think you did not generate onclick event of button properly replace button code by below
<asp:Button ID="Button" OnClick="Button_Click" runat="server" Text="Save Data" />
and check it using breakpoint on the click event if code is executing or not.
pls check with
string connectionString = ConfigurationManager.ConnectionStrings["ConnString"].tostring();
also add parathasis to webconfig connection string

I'm trying to use the Ajax autoCompleteExtender to auto complete my textboxes using a sql query in my code behind. The problem I'm having is that my code behind isn't being hit at all.
What happens instead is my autocomplete options display as the code from my masterpage.
I've done some research and the problem might be that my textboxes are in an ascx file called from my aspx file but I can't figure out a way around it. I've even tried pointing the ServicePath to a webService and it still doesn't hit.
Any input would help, thank you!

I have a stored procedure named "Graph" that should get a value to the parameter #Material, and I created a report in ASP.NET that should show a chart using the data from the stored procedure.
However, when I try to load the report I get:
An error has occurred during report processing.
Cannot create a connection to data source 'PhilipsMaterialsDataSet'.
ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'GetData' that has no parameters.
I tried different solutions but none of them worked. Also, I'm not sure if I should declare the parameter in the ASP code.
( by the way, GetData is not recognized here because it has one parameter (#Material-from the stored procedure) and for some reason, it is called without any parameters )

The error is saying GetData requires some parameters, and you have to supply them by adding a parameters like like:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData" TypeName="PhilipsMaterialsDataSetTableAdapters.GraphTableAdapter" >
<SelectParameters>
<asp:Parameter Name="X" DefaultValue="Y" .. />
</SelectParameters>
</asp:ObjectDataSource>
