call a function in the onchange event of the checkbox.
disableButton(checkboxname.Checked)
the function must be doing some thing like this.
function disableButton(var status)
{
if(status)
document.getElementById("btnName").disabled=true;
else
document.getElementById("btnName").disabled=false;
}
}

I am in the process of learning ASP.NET and read that when using Visual Studio 2005, you can add an existing .html file to your project and just rename it to .aspx to automatically convert it to a ASP.NET Webform. I've even seen it done on an "eLearning" video demo with Visual Studio .NET. However, when I try to duplicate the demo using Visual Studio 2005, it doesn't add the page directive like on the demo.
Anyone have a clue what I'm doing wrong?

It won't automatically add anything to the page. It will only change the file type.

changing the file type will just change the file type. Create a new page, and copy your HTML into it, being careful not to copy over the directives at the top. It will be exactly the same, but now you can add server controls and code behind, if you want to.

First off I realize this is a common issue and has plenty of people saying they have fixed it.
I am using VS 2005, programming in C# and ASP.NET. I have a GridView and an ObjectDataSource my GridView will display the data, but not update. I am using a three-tier application design. My DAL has on table with SELECT and INSERT type methods. My BLL has SELECT, UPDATE, INSERT, and DELETE methods. My presentation layer contains the ObjectDataSource and GridView.
When I attempt to update I get the following error:
ObjectDataSource 'odsSubdivisions' could not find a non-generic method 'UpdateSubdivision' that has parameters: intID, szName, szCity, szState, szZIP, szLegal, Name, City, State, ZIP Code, Legal Description.
The last 5 parameters are added by the ObjectDataSource I believe. I have set the OldValuesParameterFormatString to {0}, which most solutions say to do, yet no avail. I am not using Optimistic Concurrency either.
Any other suggestions. I'll try anything.

Good day to all,
I have a few panels control inside one UpdatePanel (AJAX extension), these items have drag and drop features, upon dragging these panels and dropping them at a different location, a webservice will be called from client side to update the new location of the panel in the database.
The problem now is I have another dropdownlist outside this UpdatePanel which is databind. Whenever the location of any panel is dragged and moved to a new location, the item in the dropdownlist should be different as it uses a stored procedure which is somehow link to the above attribute.
The problem I'm facing now is that I'm unable to update the dropdownlist by using the ddltest.DataBind() unless I reload the whole page instead of using an UpdatePanel. I'm quite new to AJAX so feel free to correct me on my misconcept and advise me on how should I tackle this problem. Thanks in advance
Cheers

Hi larree11
You can also place the dropdownlist inside the UpdatePanel. You have one updatepanel which contains a few panels. So whenever panel is drag and dropped you want to update the dropdownlist, so better, you place the dropdownlist box inside the updatepanel and in the drag and drop features update the dropdownlist values.
I think this will help you to resolve your problem

Hi Venk259,
First thanks for the reply... I did try this method before but the dropdownlist did not reload with fresh data whenever i drag and drop a panel.
I have set the dropdownlist autopostback to true but its not refreshing. Any idea why is it like tat? by the way the web service called by the drag and drop is done on client side by calling the webservice using javascript. Any work around?
Cheers

Please don't cross post. Answering in the C# forum, I assumed it was a winforms app.
Do you want to do a postback to get a specific item ? why not write the SQL to return only that item, and store the index in viewstate ?

Hi, I get the following error message when I run my application in the browser.
"Invalid cast from System.String to System.Byte[ ]"
I have changed cmdInsert.Parameters.Add("@docContent",OdbcType.Text) to
cmdInsert.Parameters.Add("@docContent",OdbcType.Binary)
like someone had suggested, but it still does not work. I have checked other variables for type mismatch but didn't find any. If you see anything at all wrong with my code please point it out. I would really be grateful if you can show me what is causing VS2003 to throw the exception. Thank you in advance for your help.
The following is my code to help you better understand my situation.
Imports System.IO
Imports System.Data.Odbc
Public Class Upload
Inherits System.Web.UI.Page
Private Sub Submit1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Submit1.Click
Dim strFileExtension As String
Dim StrFileType As String
Dim intFileLen As Integer
Dim objStream As Stream
Dim strInsert As String
Dim myConnection As OdbcConnection
Dim cmdInsert As OdbcCommand
If Not IsNothing(txtFileContents.PostedFile) Then
'Determines File Type
strFileExtension = Right(txtFileContents.PostedFile.FileName, 4)
Select Case strFileExtension.ToLower
Case ".doc"
StrFileType = "doc"
Case ".ppt"
StrFileType = "ppt"
Case ".htm"
StrFileType = "htm"
Case ".html"
StrFileType = "html"
Case ".txt"
StrFileType = "txt"
Case Else
StrFileType = "jpg"
End Select
'Grab the content of uploaded file
intFileLen = txtFileContents.PostedFile.ContentLength
Dim arrFile(intFileLen) As Byte
objStream = txtFileContents.PostedFile.InputStream
objStream.Read(arrFile, 0, intFileLen)
'Add UpLoaded file to a database
myConnection = New OdbcConnection("Provider=MySQLProv; Data Source=Data;User Id=myID;Password=myPWD")
strInsert = "INSERT into QUsers (docTitle,docContent,docDate,docType) values (?,?,?,?,?)"
cmdInsert = new odbcCommand(strInsert,myConnection)
cmdInsert.Parameters.Add("@docID",OdbcType.int,30)
cmdInsert.Parameters["@docID"].Values =""
cmdInsert.Parameters.Add("@docDate", OdbcType.TimeStame,14)
cmdInsert.Parameters["@docDate"].Values = DateTime.Now.ToShortDateString()
cmdInsert.Parameters.Add("@docTitle", OdbcType.Varchar,30 )
cmdInsert.Parameters["@docTitle"].Values = txtFileTitle.Text
cmdInsert.Parameters.Add("@docType", OdbcType.Varchar,30)
cmdInsert.Parameters["@docType"].Values =StrFileType
cmdInsert.Parameters.Add("@docContent",OdbcType.Binary)
cmdInsert.Parameters["@docContent"].Values =arrFile
myConnection.Open()
cmdInsert.ExecuteNonQuery()
myConnection.Close()
End If
End Sub

I am trying to insert an record in table but it gives me following error. What does it means
Cannot insert explicit value for identity column in table 'tb' when IDENTITY_INSERT is set to OFF.
seema

Hey this is not the right forum to ask this question.
pls move this question to sql/ado/ado.net forum.
And as you have stated above the problem is occurred because of the following. So
@@IDENTITY contains the last identity value generated by your statement. If you insert into a table that runs a trigger and generates another identity value, you will get back the last value generated in any table. To solve this problem you'll need to use SCOPE_IDENTITY to return the inserted value. Every procedure, trigger, function and batch is it's own scope. SCOPE_IDENTITY shows the most recently inserted IDENTITY in the current scope (which ignores any triggers that might fire).
If you want to insert a value into an identity column you can use the SET IDENTITY_INSERT statement
SET IDENTITY_INSERT Yaks ON
Insert Yaks (YakID, YakName) Values(1, 'Mac the Yak')
SET IDENTITY_INSERT Yaks OFF
select * from yaks
You can only turn on IDENTITY_INSERT for one table per session so it's always a good idea to turn it off when you're done with it.
