Forms Data Controls :: Specified Cast Is Not Valid.on Formview Checkbox
Aug 12, 2010
There is select and update SQLs in sqldatasource and checkbox in formview which is 2way databinded to an sqlserver bit field type.
it always gives same error
Specified cast is not valid
I excpect nobody posts me an "eval" solution.because update is a need for checkboxes which are attached to a bit field.
a ready-to-use small sample project with DB I attached HERE
Specified cast is not valid.

just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here. Here's the function class itself:
[Code]....
For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.
have a table that keeps track of customer data that is beyond the scope of the Membership Class, this table I am also using the Membership.CreateUser() generated user ID.When I use my INSERT statement however to create a new row in my table I keep getting the Specified cast is not valid error.This is my SQL Command (The ...refer to other fields)
Dim mySqlCommand As String = "INSERT INTO Customers (UserID, ...) VALUES (@UserID, ...)" I send it to my Write_Database(mySqlCommand, Membership.GetUser(txtUserName.Text).ProviderUserKey, ...) function which then I also tried sending he UserID as: CType(Membership.GetUser(txtUserName.Text).ProviderUserKey, SqlGuid)
Neither Works...both cause errors...My Write_Database Function is declared as follows:
Public Function Write_Database(ByVal MysqlQuery As String, ByVal UserID As System.Data.SqlTypes.SqlGuid, ...)
However Visual Studio shows that the error originates in the function calling code...
I have a formview which contains a question and 5 checkboxes with answers alongside. Some of the questions are true/false so I want to make checkboxes 3, 4, and 5 invisible.
Should this be handled in code-behind? (I don't see any ready-made events for paging through the formview) or is there a way to test data and change the visible property in;
At the moment I'm trying to keep a certain site (asp.net) alive long enough for its replacement to be build in php. However I don't know much about .net or asp.net.

I'm putting together a page that allows the user to enter a new record in an SQL table. A bunch of the fields in the table are bit datatypes. I want to use CheckBoxes to correspond to the bit datatype columns in the SQL table.
How do I bind the checkboxes to the SQL table columns?
I've already checked the row returned by my sproc and all the fields match my OcItemConstraintDetails class. Not sure why I am getting the error below :(Error: Specified cast is not valid.
I've got a list of teams which seperate into different leagues. I'm trying to show the user the league that they are in and show it from where they are in the league. This is the error I'm recieving:Specified cast is not valid.

I have a .Net 2 solution with some asp classic pages.I get a specified cast is not valid error when I access the page on my local. Below is the vb function where I get the Error:
Public Function Retrieve(ByVal vntSeqId As String, ByRef vntPart As String, ByRef vntPartKey As String, ByRef vntEntDate As String _ , ByRef vntStatus As String, ByRef vntOrigGblId As String, ByRef vntOrigNetId As String, ByRef vntOrigName As String, ByRef vntOrigPhone As String _ [code]...
At first, I thought the problem is with the source code and we were thinking the source code we have is different with the ones deployed on test and prod servers. But when I tried to upload it on the test server, I don't get the specified cast is not valid error.
I have a complicated join between a few tables but I have managed to replicate the error using linqpad and the small tables below. There are references between the COLNAME column and the YAXIS column and also between COLNAME and XAXIS that is not explicitly defined.
The error is "Specified cast is not valid", which originally I wasted time thinking the problem was converting the data returned to my object in VS 2010, but the error also happens in linqpad with no defined object. It seems insane that a bit column would cause this problem. If I change the column type to a VARCHAR it works fine. If I run the generated SQL from linqpad or sql profiler that also returns fine.
I have a custom oledb role provider that pretty much a cust and past of:
[URL]
except I've used oledb instead of odbc. I'm connecting to an oracle database and the tables have been created with out any issues. now if I go into the Website Administration Tool and try to create a new role I get the error
"Specified cast is not valid."
I can create a role directly in the database (through TOAD) and the role will show up in the .NET WAT, so I know it can make the connection and read the info just fine. I just can't create or delete or modify a role without the above error.
we have created web application project and on local computer everyting works fine. after doing deployment on our production server we get a error below

The problem is that this is occurring only on our servers, not on our local development boxes. I've tracked it down to a single property we're modifying:
event.SalesForceId = "701Q0000000AOTIIA4";
If I comment out that line, everything works fine.
I've tried:
1 ) waxing all of the code on the server and redeploying. Same issue. 2 ) Pulling down a copy of the server DB and trying it locally. Works fine. 3 ) Trying another IIS environment we have setup on the same box. Same issue. 4 ) Physically comparing ( using AdeptSQL ) both local and remote schemas. No differences. 5 ) Verifying the datatypes of both columns ( local and remote ) are the same. Also, this column is a FK to another table. I verified that both are of the same data type, down to the collation.
The server is Windows Server 2008 and the local box is Windows 7 x64. Both have all important updates setup.
The only thing I can think of is perhaps since the database and web server are on different boxes that could be an issue? Otherwise, I'm completely stumped.
I have two linqTOsql entities that has a parent and child relationship, one to many. I'm running into an issue that when I retrieve the parent record, I am unable to loop through the related records in the child table.This code fails:
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
