I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.

I added a button click event to my project as:
But since this i am getting this error saying:

There seems to be no error in my code.
I am getting error "Cannot implicitly convert type 'string' to 'System.Data.DbType".
When I am passing Stored procedure parameter it expets 'System.Data.DbType" and the Data member is declared as a string.
I am selecting the checked rows from Gridview. To achieve this i have written a lambda expression using dynamic keyword.
var dn = gvLoans.Rows.OfType<dynamic>().Where(s => s.FindControl("chkSelect").Checked == true).Select(s => s.FindControl("lblCD")).ToList();
I want the output of this in List. Can it be achieved by extending the query or i have to write foreach statement.
For the life of me, I can't figure out what the problem is with this:
tempData= from a in dx.SomeTable select a;

string searchString="BoxPkg";
object[] parameters=new object[]{searchField,searchString};
tempData = tempData.Where("@0 like @1", parameters);

I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.
how would one go about converting a string to an SQL time data type? Lets say i wanted to convert @param1 to SQL time and @param2 to SQL date.

Cannot convert type 'string' to ConstantExpression I am using the Linq to Active Directory script that is out on the net. When I do my Where clause with a pure string i manually put in "string". If I use a variable I get from a textbox (which makes sense if I am creating a search!) it will not work. I debugged and found it is having issues converting. Maybe something can be changed or maybe there is another way for me to do this?

I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".
