Specified cast is not valid error

[.Net Sports]

I have a datagrid script where I modify data in an sql dbase in
asp.net, when i hit the "update" button, I get a Specified cast is not
valid error on my 'descript' declaration, whereas 'descript' is a
multiline text box and a varchar datatype (everything else is either a
char or a datetime datatype). Am I assigning 'descript' a wrong
datatype? Tried making it a nvarchar, still get same result

How long is the text in the box? Is it constrained? If not you might have to
cast to a text type and give it a length which is long enough to hold the
amount of data that can be shoved into field. I also think there may be some
magic for a multi line text box, instead of placing the contents directly
into a parameter, try casting out as a string first and see if you get the
same issue.
