I am trying to insert checkboxlist values into SQL using a stored procedure.Getting This error Item In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. System.Data.SqlClient.SqlParameter Here's my stored procedure

I have a list of options on my site that a user can select. What I want to do is provide functionality to limit the amount of content the user gets based on his selection in a CheckBoxList. Once he's selected what he wants, he'll click Save and his selection will be written to the database. The CheckBoxList is initially populated from the Modules table. This provides a list of modules that the user can select. When he clicks Save, the code needs to loop through this CheckBoxList and "pick out" the values for the CheckBoxes that were checked, disregarding the ones that weren't. The problem is that whether a CheckBox is checked or not, the debugger returns a False value for the CheckBoxList.Items(i).Selected property.
Here's my code:
Private Sub AddUpdateOrg(ByVal OrganizationName As String,
ByVal Action As String, Optional
ByVal Target As Integer = Nothing)
[Code] .....
Its possible that this behavior is the result of a postback from the save button. Upon further examination of the code, I've reconsidered the possibility that this issue is caused by a postback as the CheckBoxList is not bound on page load.

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.
I have some checkboxlist like this:

Essentially, what I'm trying to do is get a list of values out of a database and put them into a bunch of checkboxes. When the user submits their selection of these checkboxes, I need to see what they've chosen.So I have no idea how many checkboxes I'll need, or what the values will be. I will however be listing different categories. I would like the final result to look something like this:
<h1>category 1</h1>
<input type="checkbox" name="cat1" value="avalue">
<input type="checkbox" name="cat1" value="anothervalue">

However, I found this seemes to only work in the front end. I need these values passed back to the backend so I can decide what to do with them.
this its a very silly problem i have with CheckBoxList control, i dont know if its just me or what but the whole idea of the control its just great but the implementation its very confusing.
im trying to eval something like this
if CheckBoxList.Items.Item(CheckBoxList.Items.Count-1).Checked=true then.....
or something like
CheckBoxList.CheckedItems.Item(CheckBoxList.Items.Count-1) = Checked then...
the problem its that i dont know how does the checkboxlist works but it just sucks that they had to make it so confuising....
i've handled lots and lots of collection controls and they all work in a similar and simple

i am able to pass the checked value of the checked list box to a list box

i am going to save the values [ for instance mat_name ] on the listbox in the database
but i need the id [ for instance mat_id ] of that value
how can i connect a checkboxlist with a database?

I have a personalized webbrowser in VB 2005. It fills values into a form and submits the form.
The first page is "login.php", the next page is "home.php"
SendKeys.SendWait("{TAB}")

SendKeys.SendWait("username")

View 1 RepliesI have a large form that reuses several elements, so I decided to create a usercontrol with some common fields. The problem is when the form is filled out by a user and submitted, how do I reference those values so I can input them to my database???
Example:
Using Conn As New SqlConnection(connect)
Using Cmd As New SqlCommand(SQL, Conn)
Cmd.Parameters.AddWithValue("@Acct_Company", txtPartner.Text)
Cmd.Parameters.AddWithValue("@Acct_AccountNum", txtPartnerAccount.Text)
So, above two Cmd lines are for normally inserted textboxes in my form, but what would the line look like to reference any usercontrol form fields?
I am trying to display value of the field ("UserID") for every row exists in datatable to checkboxlist(make the checkboxlist item selected).

Private Sub DisplayRoleUser()
Dim conn As SqlConnection
Dim cmd As SqlCommand

I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?
View 2 RepliesI have a form that creates a row of checkboxes depending on the type of analysis the user wants to perform on the incoming file. I need to be able to determine if the checkbox is "checked" but I don't know how to do that when the controls are created at runtime.So right now I have a loop going through all the controls on the form and selecting the appropriate case: for instance chkbox1, combobox1, etc. Now I can access the values of the control by using Me.Controls.Item(chkbox1) but after that the only thing resemebling checked is .Text which wouldn't be accurate. how do you workaround the .Checked property of a checkbox when it is created at runtime?
View 2 RepliesI have a view with a few checkboxes that can be selected or unselected. I'd like to always register any change in a checkbox, without the use of a submit button (the user could forget to do it, and it would waste time). So, is there a way to handle this inside the view? Up to now, I've only used the controller to do that job.

How can I get all the selected values from a check list box? I tried using the name of the check list box (clbLike) but it only returns the first value checked. How can I return all values checked?
View 15 RepliesI have a (checked) listview with values in the subitems. I am trying to make a simple sum of the checked values, but I can't seem to get it to work. The values returned aren't correct.
The idea is that each time I check or uncheck a row it re-calculates the values from subitems(2).
Here's what I was trying:
vb.net
For i = 0 to Listview1.CheckedItems.Count - 1 Label1.Text = CDec(Listview1.CheckedItems(i).Subitems(2).text) + cdec(Listview1.CheckedItems(i).Subitems(2).text)Next i
I have (text) values like 77.50, 115.60, etc.
I'm trying to loop through a column of checkboxes to see how many checked values there are in that column. The user has to have 2; no more, no less than 2, otherwise an error should show up.

The error message still occurs when I have only 2 chosen in that column. I even tried this

View 1 RepliesI am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.
