Tri-State Check Box

I need to make a tri-state check box. (It's values will be off,
checked-always on, or 1-run once)
Would I be correct in assuming the best way to do this is to make some kind
of custom control that displays a "checkbox". The control would have JS in
it to change a graphic image that represents the box. If this is the case,
how would I read in the selected value once the form is posted? I'm
planning on having a couple on the same form and I really don't want to
autopost when each box is clicked on...too much overhead...
Thanks.

Good idea...I could program the control to create a hidden field (with a
unique ID) for each checkbox...then just have a little routine to loop
through all the Request.Form items...
Thanks.

Trouble posting to Database from Drop Down List and Text box

I'm having real trouble posting from the webpage back to a database. This is supposed to be one of the easiest things to do in ASP.NET. I've checked viewstate on all of the controls and at the page level and all are set to true.

When I type in some text information, no other characters but plane text, and hit the submit button the text disappears from the box, the drop downlist returns to default, the subroutine runs and an empty space is submitted to the database.

I've verified that the procedure in my namespace is running correctly by allowing the subroutine in the code behind to trigger the SPROC in the namespace. The 'hardcoded' values are inserted into the database.

I also placed a label.text = textbox.text into the subroutine and it is always set to a blank. Even on page intialization. None the less, I wanted to see if running the subroutine would place text inside of the label and it didn't. If I hard code the label, such as label.text = "stanley" then stanley appears when you click the link button. Thus, I'm sure that the subroutine is running, its appears that the text in the text box is being lost when the page makes a round trip.

Any ideas?

SethLet's see your code.
Be sure that you are wrapping any code that initializes the values textbox and dropdownlist in your Page_Load with a check for IsPostBack:

 Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 If Not Page.IsPostBack Then
 'Initialize initial values of textbox and dropdownlist here
 End If
 End Sub

If you don't, each time the page postsback, the controls will be reset back to their initial state, probably blank for the textbox and no selected item for the drop down list. Remember that when the page posts back, Page_Load will run BEFORE any of the web control event handlers.

Trouble updating

I have a Access database with 2 text fields. I'm reading one field into a text box, changing the value in the textbox and attempting to update the database with the new value. The page loads fine with the correct value in the textbox, but I'm getting a error on the Update statement. Below is the code. Any suggestions?

Sub LoadInventory()
Connect()
Dim strQuery As String = "SELECT Type, Number FROM Inventory WHERE type = 'squares'"

Dim dbComm As New OLEDBCommand(strQuery, objConnection)
Dim reader As OLEDBDataReader = dbComm.ExecuteReader()

reader.Read()
txtAmount.Text = reader.GetString(1)

reader.Close()
Disconnect()
End Sub

Sub btnChange_Click(ByVal Sender As Object, ByVal E As EventArgs)
UpdateInventory()
LoadInventory()
End Sub

Private Sub UpdateInventory()
Dim strSQL As String = "UPDATE Inventory SET Number = " & txtAmount.Text & " WHERE Type = 'squares'"
Connect()
Dim dbComm As New OLEDBCommand(strSQL, objConnection)
dbComm.ExecuteNonQuery()
Disconnect()
End Subinstead of

Dim strSQL As String = "UPDATE Inventory SET Number = " & txtAmount.Text & " WHERE Type = 'squares'"

try this

Dim strSQL As String = "UPDATE Inventory SET Number = " & Convert.ToInt32(txtAmount.Text) & " WHERE Type = 'squares'"

Jeff
Jeff,

Thanks for your reply. That however didn't work. Could it be the way I have my access database setup?

Jeremy
Jeff,

Does it work when you try putting in a static value for txtAmount.Text such as this:

"UPDATE Inventory SET Number =1 WHERE Type='squares'"

If it does work like that, then try doing this:

Try
 Dim dbComm As New OLEDBCommand(strSQL, objConnection)
 dbComm.ExecuteNonQuery()
Catch dbException As Exception
 Response.Write(dbException.ToString())
End Try

Tell us what the exception is. Besides, it is always good practice anyway to put database queries inside a try statement - there are just way too many things that could go wrong to not catch those errors.

Trouble With Session State

Hello,
I am having trouble with session state in my asp.net 1.1 C# web app. I
am trying to program either a popup box warning of expiration, or I
may do a redirect to the home page upon expiration.
But I can't seem to get started, because I am getting values that I do
not understand. In IIS settings, I stopped my website/app and went
into the properties for it and selected the "Home Directory" tab. Then
I clicked the "Configuration" button and selected the "Options" tab.
Then under the "Application Configuration" group, I verified that the
box for "Enable session state" was checked. Then I changed the value
to "2" (just for testing). I then saved and restarted my website.
Then I opened the site in Visual Studio.net and went into the
web.config file and changed the forms authentication timeout value to
"1" (again, just for testing).
Then when I ran my code, in debug mode/step through, I can see that
the value being returned for "this.Session.Timeout" is "15"? What's
going on here? I thought that when I set the value in IIS, it would
make it 2, but that didn't happen? Where is this number coming from?
How can I change/control it?
Your help is much appreciated.

I believe these values are for classic ASP, not for ASP.NET.

So how does one set session timeout for asp.net?
Use the sessionState entry in Web.Config...
