In what mode you are running your application

1. Debug
2. Release

if it is in release mode then you cannot debug it.

Secondly, try checking web.config compilation option

I have a gridview that I am trying to validate 2 fields so that one is not greater than the other. When I run the code, I get the following error.

Server Error in '/WebSite' Application.
--------------------------------------------------------------------------------

Control 'inStock' referenced by the ControlToCompare property of 'CompareValidator2' cannot be validated.

I believe the problem is in my asp code and not my c# code. Here is my asp code for that section.

<asp:templatefield headertext="Ordered Amount" xmlns:asp="#unknown">
    <itemtemplate>
       <asp:textbox id="amount" runat="server" width="30px" />
       <asp:comparevalidator id="CompareValidator1" runat="server" errormessage="Must be a number">
            Operator="DataTypeCheck" Type="Integer" ControlToValidate="amount"></asp:comparevalidator>
            
            <asp:comparevalidator id="CompareValidator2" runat="server" errormessage="Amount ordered is greater than amount in stock">
            Operator="LessThan"  ControlToValidate="amount"  ControlToCompare = "inStock"></asp:comparevalidator>
    </itemtemplate>
    
    <headertemplate>
    Ordered Amount
    </headertemplate>
                    
   </asp:templatefield>
   <asp:templatefield xmlns:asp="#unknown">
   <itemtemplate>
    <asp:label id="inStock" runat="server" visible="false" /> 
    </itemtemplate>
    <headertemplate>
    </headertemplate>
   </asp:templatefield>

You can't compare to a label.

As a workaround, you can add a textbox on your form and set the text to the same text as the inStock Label.

Then to hide the textbox add txt.style.add("display", "none") in your code behind.

I didn't get any requirements for the signature

Ok so I did that but now it doesn't validate it. That is to say if the number is too high, it still goes through. Here is my code.

<asp:gridview id="GridView1" runat="server" onselectedindexchanged="GridView1_SelectedIndexChanged" width="591px" xmlns:asp="#unknown">
            
            <selectedrowstyle backcolor="Blue" />
            <columns>
                <asp:templatefield>
                    <headertemplate>
                        Amount Ordered
                    </headertemplate>
                    <itemtemplate>
                        <asp:comparevalidator id="CompareValidator1" runat="server" controltovalidate="amount">
                            ErrorMessage="Must be an integer" Operator="DataTypeCheck" Type="Integer"></asp:comparevalidator>
                        <asp:comparevalidator id="CompareValidator2" runat="server" controltocompare="inStock">
                            ControlToValidate="amount" ErrorMessage="Amount ordered  is more than is available."
                            Operator="GreaterThan" Type="Integer" ValueToCompare="inStock"></asp:comparevalidator>
                        <asp:textbox id="amount" runat="server"></asp:textbox> 
                        <asp:textbox id="inStock" runat="server" visible="False" width="1px"></asp:textbox>
                    </itemtemplate>
                </asp:templatefield>
                <asp:templatefield>
                    <itemtemplate>
                         
                        <asp:textbox id="TextBox1" runat="server"></asp:textbox>
                    </itemtemplate>
                </asp:templatefield>
            </columns>
        </asp:gridview>

You can not set visible=false. If you do this the control is not rendered (no html is generated). Set the style property display to none. That way the control will still be rendered (html is produced) but it will not be visible to the user.

So you want a job that you can't do, and you want us to do it for you? If I knew where you were applying I would contact them and let them know that you don't know what you are doing.

hello , everyone . I want to know what is the best way to start a long running process in asp-net , and keep it running until it finishes (when it will write its result to a database) , no matter if the user closes the page or does some other stuff . Of course , if it's possible to do such a thing . Thank you!

It depends what you mean by 'long running'. The project I'm working on at the moment was using a web page to do a data import (~10 hour job) and we had numerous problems with the app pool recycling, people closing their browser etc.

My advice - if you've got something that takes that long to do, run it anywhere but within a web form as your first choice.

It definitely isn't definatley

Thank you for your posts . Well , the "long running task" consists of running some scripts . It won't last 10 hours , but i suppose some of them might take several minutes . Shall i choose the async handler in this case ?

No. You should just use threads and let the .NET application takes care of them according to the MSDN article.
