Web Forms :: How To Use Varchar Table Value To Display Checked Boxes
Jan 21, 2010
To preface, I have just started leaning ASP.NET and have not worked with VB in 10 years. My boss just dropped an "easy" project in my lap that I don't even know how to start and he wants it done tomorrow (literally).
The desired output is simple - a form elsewhere on the site uses a field called status codes associated with a record to limit the values (other status codes from the same list) in a dropdown box. He wants a page that enables an admin to change what values are available in the dropdown box:
It should have a dropdown box where the admin can select a status code to update.
Then it should have a 2 column grid listing all status codes. The first column should consist of checkboxes where those in a lookup field (used to limit the dropdown values mentioned above) are already selected. The admin should be able to check/uncheck all the boxes and update the lookup field. The table has basically three fields:
Status ID: a numeric ID (ex. 10)
Status Code: a description (ex. "Sent to SSC")
Lookups: varchar, comma separated values that correspond to Status ID (ex. 10,20,30,190,980,990)
The Lookups field confuses me the most. I'm guessing that I need to read in the values into an array and write something to check the boxes that match. Then an update statement to combine back together with commas and update the field. I have no idea how to do any of that. All I have so far is a dropdown box listing status codes.

I have a gridview and users would select some records and would click on the submit button and i will be saving those records into database using a stored proc.... now .... just below the gridview and above the submit button there are few checkboxes by default they wud be checked. How would i save the selected values and the checked boxes in database i wrote the stored proc for the gridview but how would i save the checked checkboxes into the same table.
For i As Integer = 0 To gvSelectScreen.Rows.Count - 1
Dim chkTemp As CheckBox = TryCast(gvSelectScreen.Rows(i).FindControl("cbStatus"), CheckBox)
If chkTemp.Checked Then
ContractNumber = gvSelectScreen.Rows(i).Cells(0).Text
ClientProgramNumber = gvSelectScreen.Rows(i).Cells(1).Text
ClientProgramName = gvSelectScreen.Rows(i).Cells(2).Text
StartDate = CType(gvSelectScreen.Rows(i).FindControl("txtStartDate"), TextBox).Text
EndDate = gvSelectScreen.Rows(i).Cells(5).Text
Dim connStr As String = ConfigurationManager.ConnectionStrings("MainConnectionString").ConnectionString
Dim myCon As New SqlConnection(connStr)
Dim cmd As New SqlCommand("usp_ParametersFromGrid")
Dim dt As New DataTable
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@ContractNumber", SqlDbType.VarChar, 22).Value = ContractNumber.ToString()
cmd.Parameters.Add("@ClientProgramNumber", SqlDbType.VarChar, 22).Value = ClientProgramNumber.ToString()
cmd.Parameters.Add("@ClientProgramName", SqlDbType.VarChar, 100).Value = ClientProgramName.ToString()
cmd.Parameters.Add("@StartDate", SqlDbType.VarChar, 20).Value = StartDate.ToString()
cmd.Parameters.Add("@EndDate", SqlDbType.VarChar, 20).Value = EndDate.ToString()
cmd.Parameters.Add("@RequestID", SqlDbType.VarChar, 50).Value = RequestID.ToString()
cmd.Connection = myCon
myCon.Open()
cmd.ExecuteNonQuery()
myCon.Close()
End If
Now above the submit button as i said, there are few checkboxes and they are checked by default...how would i save the selected item (in the gridview and the checked checkbox values in the same row in the database(sql server)

I generate my check boxes dynamically:
for (int i = 0; i < dtCommon.Count; i++)
{
CheckBox newBox = new CheckBox();
newBox.Text = dtCommon[i].userName; [code]...
And when the save button is pressed I call this function:
protected void SaveUsers(object sender, EventArgs e)
{
}
How do I know which check boxes the user has checked?!

I have heard that even though the maximum varchar size is 8000, that we should not go higher than 7500 for the size value. What is the logic behind this advice?

I save dates as a string in a varchar data field named "TilDato" in a SQLServer-express table. I want to filter the records smaller than a specific date from a variable in the script. I try the following statement, but it does not seems function logically.
objCmd = new
SqlCommand("SELECT * FROM Reservering WHERE @laanedato<=TilDato",myConn2);
objCmd.Parameters.Add("@laanedato", laanedato);
objRdr = objCmd.ExecuteReader();

I am working on building a webform in visual studio ultimate 2010. What I need the form to do, for purposes of ease of use and data integrity, I have a list of service providers that, when a visitor has subscribed to service from say, Sprint, in order for us to proceed with our business practice, we would need their Sprint PIN account. So when they check 'Sprint', a label that says Enter Sprint PIN: and a text box should appear.
Of that label and text box control, on the properties pane, i set the visible property to false, then erased that, and put it in the page load section of the C# code and erased it, since neither scenario worked. This is the current code I have, and either they appear, or are invisible, and when the check box is clicked, nothing happens...

I am hoping this is not a silly question but I have been struggling to find an answer. I have created a web application to insert data into SQL database using T_SQL and stored procedures as I needed to update several tables at the same time. The design of a particular page is using text boxes and dropdown list's and not the default gridviews or details view as I wanted the page structure set out in a particular way. Anyways I now want to create an update page which I will get redirected to from a search page.My question is how do I assign the column values to text boxes or Dropdown lists from my Select statement. I was thinking of having a event in the page load method. Sort of like this 'Select InvoiceID, Invoicetype, Notes FROM TblInvoice Where Invoicenumber = @Invoicenumber " the parameter value @Invoicenumber will be assigned via the search page so I will also need to pull that in on the page load event. So my page would look something like this if say the:-
Textbox1 = InvoiceID(Value)
DropDownnlist1 = Invoicetype(Value)
Textbox2 = Notes(Value)
how to write this in a code behind page. I would then click a button to update the values if I changed them and write my update statement for the button click event which I know how to do .

I'm working on the admin tool and am using DetailsView to edit the records (.net 2.0). In the screenshot below, the left is the GridView, and the right is the DetailsView. When a user clicks "Select" in the GridView, I am trying to display the assigned Sectors stored in the database via a checkboxlist (activities can have multiple sectors). This way, the Admin user could just uncheck/check what sectors they want to change. Unfortunately, I can only get the first sector that's stored database to show up.
Is it possible for the Checkboxlist control to allow for more than one box to be checked at the same time? If so, do I need to create a custom funcion (via looping) in order to populate the checkboxlist accordingly? I've ran into 3 articles so far that imply that, but can't get the For Each to work for my situation:
This is my select statement:

DetailsView on front-end:
