You need to provide more information. Although it's the first line of your code which is making trouble. Have you checked what type of value is there in ht["UserID"]?

Solution 1

Quote:
string CreatedBy = UsrId

Should be

C#

string CreatedBy = UsrId.ToString();

or (better)

C#

string CreatedBy = ht["UserID"];

Quote:
Convert.ToInt32(Convert.ToString(Session["UserID"]).Trim());

The above line makes no sense to me. What's its purpose?

Solution 3

C#

Int64 UsrId = (Int64)ht["UserID"];
string CreatedBy = UsrId;Convert.ToInt32(Convert.ToString(Session["UserID"]).Trim());

Simply:

C#

string CreatedBy = Convert.ToString(UsrId);
OR
string CreatedBy = ht["UserID"];

will work
Hope it Helps :)
