Jun 25, 2010
I have the below code in my project..however its giving me an error on the update(bolded line)..please help me on this..
Private Sub ChangePassword1_ChangedPassword(ByVal sender As Object, ByVal e As System.EventArgs) Handles ChangePassword1.ChangedPassword
lblTempPassword.Text = ChangePassword1.NewPassword.ToString
CustomerName.Text = CType(Session("UserName"), String)
Dim FV1Updobjconn As Data.SqlClient.SqlConnection
FV1Updobjconn = New Data.SqlClient.SqlConnection()
FV1Updobjconn.ConnectionString = ConfigurationManager.ConnectionStrings("ASPNETDBconnectionString1").ConnectionString
FV1Updobjconn.Open()
Dim dtUpdating As New Data.DataTable()
Dim sqlUpdating As String = "UPDATE [SuperAdmin] SET [TempPasswd]= @SU2TempPasswd, [TempPwd]=@CU2TempPwd WHERE ([CustomerName] = [@CU2CustomerName])"
Dim cmdUpdating As New Data.SqlClient.SqlCommand(sqlUpdating, FV1Updobjconn)
cmdUpdating.Parameters.AddWithValue("@SU2UserId", UserIDValue.Text)
cmdUpdating.Parameters.AddWithValue("@SU2TempPasswd", lblTempPassword.Text)
cmdUpdating.Parameters.AddWithValue("@CU2TempPwd", False)
cmdUpdating.ExecuteNonQuery().... I get an error here saying..INVALID COLUMN "CU2CustomerName"
' Dim adUpdating As New Data.SqlClient.SqlDataAdapter(cmdUpdating)
' adUpdating.Fill(dtUpdating)
' Get the values needed to be passed on
' CtSUCompanyName.Text = dtUpdating.Rows(0)("CompanyName").ToString()
' CtSUCatPurch.Text = dtUpdating.Rows(0)("CategoriesPurchases").ToString()
FV1Updobjconn.Close()
End Sub
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
I have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.
My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:
[Code]....
But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.
What I really need to do is the code behind equivalent of
Is it possible to perform an update command which performs addition using a value from a textbox? For example: User inputs a number into TextBox1 (I use regular expression validation to ensure this is an integer).
[Code]....
Basically if the user inputs 5 into TextBox1, I want the update command to subtract 5 from that user's ballance.
I developed my application form in aspx page its such a huge form(6000 lines), I used update progress there for that updatepanel, But i cant able to see the update progress icon when i rendering the page.
I'm working on a simple demo project so that I can learn some things about ASP.NET's AJAX capabilities. My problem is that I can't seem to get an UpdatePanel to work properly with a CheckBox inside of it. Here is the markup I'm using in my .aspx file:
I am experiencing problems with the Ajax Update Progress control.
My application is about writing some comments and uploading a picture and when the picture is the process of being uploaded I would like to show an update progress. This is my code:
[Code]....
- when the button is clicked I see the update progress message for a couple of seconds but the picture and the text are not uploaded- I need to click the button again in order to see my picture and text uploaded but in this instance I don't see the update progress message.
I have one button on my page. On click of this I need to run four methods parallely in four saperate thead and need to show the progress bar for each method. Also need to update the label controls form those threaded methods.
Also I need to user Update panel of AJAX control tool kit to avoid post back to user.
I have used the read pool for that. When I remove the update panel the code works fine and update four labels but when I put the update panel it is not updating the labels.
we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?
I want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
I am not sure if I am in the right spot here because this really doesn't have to do any datacontrol but hopefully somone can give me a hand with this.
Basically I have a bunch of TextBox controls on a page that are displaying the data I want but when I try to run an UPDATE query on the record I get nothing. The record values don't update and I don't appear to get any exceptions.....I am actually kinda really baffled on this one, here is what I have for the update code: [Code]....
Btw, if there is an easier way to do this with a control I am up for suggestions as I am just going off of some of my old VB6 ways
I have a sproc that updates data in the table but I'm having difilulties with one of the params that is of type datetime. In the sproc, a decision is made based on this date such as if the date is null/blank/emplty, update data, else delete data. I've tried things like
if(@Date_returned IS NOT NULL)
if(NOT @Date_returned = '')
if(@Date_returned = '')
if(@Date_returned > '01/01/0001')
but it always defaults to the "else" part where it deletes my data. The date is passed to the sproc from a .net calendar form object via a bll/dal and I can track the variable with its value. When I actually pick a date it has the date I've picked, otherwise it has a devault value of "01/01/0001 ....".
The users of my webapplication are validated using database connection. This requires each user is a sql server database user. While logging their validity is checking by trying to create a connection using userid and password entered by the user. If connection opens successfully, it is a valid user. I also have a page in application to change the password, where sp_password is used to updated database password.
string connectionString = ConfigurationManager.AppSettings["DBServerName"]; //try to create a new connection dynamically using user id and password connectionString = connectionString + User ID=" + userId + ";Password=" + password; using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); }
The problem is after i change password, and logout and try to login, i am able to login using old passwd also. The line of code which creates and open connection succeeds with both old and new password. If i stop and run the application again this works.
I have a form that gets populated by LINQ and I want to be able to update the database using that same form. The form is populated by grabbing a querystring (for example, "edit=10") and searching the primary key for that record. So far so good. I have a button attached to the function below which is supposed to use LINQ to update the database with data from the form. I get no errors, but for some reason, it is only updating one field (Last_Updated) instead of all of them.
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I am working with odbcCommand class, in one case I got error that QueryTimeout Expired. Even though this SP is taking only 3-4 secs in DB to execute these specific values, When I set the CommandTimeout=0, then it worked fine.
1)Is it necessary to always use this property while working with Command Class.
2)If it is not suggested to use, but still if I use it then how it will impact the performance.
Below is my code sample.
OdbcConnection conObj; OdbcCommand cmdObj; OdbcDataAdapter daObj = new OdbcDataAdapter(); public DataTable GetIFAContractNoteData(string RecipientIDIFACN, DateTime BatchDateIFACN, int TransmittalReportIDIFACN) { conObj = new OdbcConnection(GlobalVariables.strDsnName + ";" + GlobalVariables.strDsnDataBase + ";" + GlobalVariables.strDsnUserID + ";" + GlobalVariables.strDsnPassword);
Since I was not able to figure out my previous problem I decided to go ahead and make my own update statements and change the update command on a datasource I have. So I have a few textboxes and whatnot that allow you to change data and then click an update button. When I click that update button the page seems to refresh as if it was updating the record but the data in the boxes reverts back to what it was. I also created a ONUpdated sub and the label text change does not show.
I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.

have a gridview which i a using for sorting data in it.IT sorts the first time i click on cloumn in ascending order.When i click on column again , i want to sort it in descending order again , but it does not happen ,
Now, when you select an item from the 1st DropDownList, you go t the right page, but then if you click on the browser back page, and select an item from the 2nd drop down, still the 1st drop down event will be fired and then you land on the Fixtures.aspx page again instead of Results.aspx.
I assume it is not a bug and I am missing something in here. I tried Response.Redirect("~/pageurl.aspx",false) as well but still it cause the same sort of problem .
