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

Use ViewState to hold the DataSet and the Increment counter.

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
End Class

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.

There is a good tutorial for what you're trying to do by Faisal Khan. It starts with uploading images to a database and ends with displaying images from a database. Hope this helps, just go to the site below.

That's a debugging error. When do you get it ? Is it all you get ?

Not sure if this is the correct board, but I'll try here.
I am trying to add a custom aspx page to my Sharepoint site. Here are the steps I've taken:
- Published my site with VS 2005
- Created a blank aspx page with Sharepoint Designer
- Copied the published aspx page into the newly created one in Designer
- Added the dll to my Sharepoint bin folder
- Added the following line to my web.config:
<br />
<SafeControl Assembly="App_Web_mzeq_hmf" Namespace="_Default" TypeName="*" Safe="True" /><br />
This is apparently the only way to have custom aspx pages in WSS 3.0/MOSS 2007, which is annoying.
When I try to run the page I get this error:
An error occurred during the processing of /contact.aspx. Value cannot be null.
Parameter name: key
I have no idea what that means. I thought it might have to do with not having a PublicToken parameter, but that was just a blind stab at what that might mean.
Any help on this would be great!
Thank you!

Hello.
When I add a new record in my gridview, I would like to select directly that new row instead of returning on the first row.
I'm using Primarykey in the gridview, and the gridview paging.
Is it possible to do that ?
Thanks a lot for your help.

Hi All,
I am writing internet application proxy for which i have to convert HttpContext.Current.Request object to WebRequest object such that i pass on all the information from Request to WebRequest.
Any ideas?
Thanks,

You can't convert them, they are two seperate objects for different purposes. What are you trying to accomplish?

I am trying to write internet application which will be hosted by me and used by client but application need to access the database which is exposed as webservice in intranet.
Now, i was thinking of hosting a application proxy on client side which will access webservice in intranet environment and then call my application in internet. For an example say client need access Default.aspx page, it will go the application proxy and depending on which page i am trying to access application proxy will get the information from client database and then it will reconstruct the webrequest and send the request to my application.
Thats what i am trying to achieve. Let me know if i can achieve above funtionality some other way.
Thanks,
Amit
