ASP.NET/C# problem
« on: July 30, 2012, 12:44:19 PM »
So my problem is the bold line of code is giving me "Index was outside the bounds of the array." error. It's an issue with the italicized bit. Am I not able to make an array out of DropDownLists and then add to the list? Should I use something else like an arraylist or collection or something? Oh the 'ID' variable is set to 1 right now. Any help would be appreciated.

         
        DropDownList ddlHospital = new DropDownList();
        DropDownList[] dynamicDropDownList = new DropDownList[ID];       
       
        ddlHospital.ID = "dropDownList" + ID.ToString();
        ControlsPlaceHolder.Controls.Add(ddlHospital);
        dynamicDropDownList[ID] = ddlHospital;
       
        ddlHospital.Items.Add(new ListItem("Select a Hospital"));

In the italicized line, you're referencing the second element of the array, when the array is only one element long.  That's probably your problem.  Should be

dynamicDropDownList[0] = ddlHospital;

That did the trick

I forgot that C# doesn't start at 1. This is my first programming job in about 6 years, I'm a bit rusty. lol


Thank you, for the help.  :tup

Indexes for arrays almost always start at 0, actually.  They definitely do in all languages with C-style syntax, anyway.

Best of luck!

I actually once worked with a C toolkit that used the memory address of the zeroeth element for storing the number of elements in that array (by casting it to an int regardless of what the array type actually was), and the first real array element started at the +1 element. It was a total clusterfuck to debug.

Two words: Research Code.

There's a lot of CS PhD's who can't code their way out of a paper bag. They write horrendous code, and as long as it doesn't crash until their experiment is over, it's golden.

Oh I see.. I feel your pain. The hospital I work at uses a patient care system that is comprised entirely of flat tables. Not a single relational database in the whole system. It's horrible and I hate everything about it.

Indeed. Our company has just taken on a huge health service project - apparently their databases reek of that same problem.
