• Re: <<Input string was not in a correct format>>

  Are you linking to this page from another page in your app, taking in user input (and putting this input in the querystring) ? If so, use a validator control to ensure a number is entered in the textbox when the user clicks the submit button. Then, in your page, you should do something like: int id = 0; if(Request.Querystring["ID"] != null) { try { id = Int.parse(Request.Querystring["ID"]); } catch(Exception error) { // your err handling } } If you are using .Net 2, you can use things like Int.TryParse

• Re: Code-behind cannot find my literal control

  Are you editing a page which was previously created in VS2003 ? Using Web Application Projects Model ? If so, when moving to VS2005, the IDE no longer created the protected instance of the control automatically, eg, protected System.Web.UI.WebControls.Literal CheckBoxIDsArray You may need to manually add this. If you are using a page which was added in your solution via VS2005, it should be a partial class (check for a PageName.cs.designer file in the solution explorer). Check this (IDE Generated

• Re: setting a property with a condition

  I would use a method rather than a property....setting a property only really accepts the value for the property itself...not any other conditional kind of parameter. Use something like (in C#) : private void SetSomething(string thingToSet, string valueToSet) { switch thingToSet { case "E" : qText_E = valueToSet; break; case "F" : qText_F = valueToSet; break; } }

• Re: Delete file from server when database instance is deleted

  The DetailsViewDeleteEventArgs contains a Keys property which will relate to the DataKey property of your grid/view. You should also be able to use e.Values["ImagePathFieldame"] to get hold of this value.

• Re: How to stop button click event from firing

  To avoid the event firing on the client, you need something like onclick='return checkok();' in the button, and then in your checkok jscript function, return true or false depending on your condition.

• Re: How to dynamically create pages each time a user signs up?

  For EditUser, you wouldnt use querystring at all. You would simply get the username out of session and display the page relevant to that userid. No querystring needed at all...theres no point if you have the username of the current logged in user in session ! ViewUser will use querystring though.

• Re: How to dynamically create pages each time a user signs up?

  Yes, almost certainly. I used querystring as a simple example, but realistically, when a user is logged in, you would have their username/id stored in session. Glad to help
