setting a column value in code for an updatable ViewGrid

Is there a way to set the value for a column in code when a ViewGrid row is edited? I have a row-last-updated date that is a required audit field in all our systems (required by data management). I don't really want the user updating this field as it should always be system controlled. If I create an editable ViewGrid tied to either an SqlDataSource or an ObjectDataSource, the field seems to only be updatable by the user. I can set it the first time by setting the DefaultValue in code but that has no effect after there is an initial value in the column. Do I need to comple

Will running Windows .exe from ASP.NET web page cause memory prob

Hello Community IIS is how we deploy an ASP.NET web application. The reason I ask that question is because I was told that .exe files take up alot of memory when they run and the more times it is called by multiple users the more memory it uses which is why ClickOnce deployment is preferred over having users run an .exe file. If I put the Windows application (.exe) on the web page and allow users to access the Windows application by clicking a link on the web page that executes a dos batch file that executes the Windows application (.exe), if mulitple users acce

js string in aspx page

I have a javascript function in my aspx page that is grabbing values in ddl and textboxes. I am forming a string to call the report server page via url and having problems. I suspect it has to do with string conversion of values pulled from the page, but I cannot figure out why as it works in other areas of the page. The commented out section does work when hard coded. Below is the snippet of js that I am having trouble with. Can someone point out the problem? I tried it both with and without the .toString() function. Thanks. var varQuarter = new String(

I have a folder with a web site I'm developing which is connected to a database. Every time I move the folder to a different computer it's a pain when I have to move the database and change the connection string.

ModalPopupExtender and Required Field Validator

Hi, I have a ModalPopupExtender that displays a panel when a button on the form is clicked. How do I get a required field validator to work when the user clicks the OK button on the panel? For example, city is required. I have set the city textbox, the city required field validator and the OK button in a Validation Group separate from any of the other controls on the form, however, the city validator is preventing my form from working as expected (when the panel is not even visible), it's like it's validating all the time.
