>>>Check duplicate while inserting record from Texbox.

Hi, On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value. Then if user will provide some other telephone number then he allows to insert record. For insertion of record I used ObjectdataSource. User will enter telephone number in a simple textbox. I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit. Any idea would be appreciated.

How to check if record is added in access database



I'm trying to put a registration page together in Visual Web Designer.

I would like to send a confirmation Email after someone is leaving his registration data and pressing the INSERT button.

The key fields in my database are: Email, Name, Surname, Address

Before I send the confirmation Email I would like to check if the email value entered in the form is realy added to the database.

Please for help in this matter. I was copy past already some C code in my page, therefore it will be fine if the code can be in C.

Again, I need help to:

- checking if record is realy added to database after pressing INSERT button

- setup the confirmation Email

Thank you in advance.

Formview check for duplicate value before insert

I've looked at some posts on here but I keep getting errors.  I am just trying to see if an email address exists already before the insert and if it does, have a label display that message to the user. From what I read so far, it looks like I could do a query in the ItemInserting event.  I just need help on the code.  Thanks in advance for any help.. Here is the Code Behind.....where I assume I can do the duplicate check in the ItemInserting event...

Check if record exists in mssql database c# code


Hello everyone!

I coded this page a while back, but I'm thinking there must be a better way to do this.  What I want to do is check real-time if various records exist in my database from a function in my C# code.  What I've done is added a sqldatabase onto my page, as well as a gridview.  Here is what I have done to verify if a record exists.

public bool RecordExists(string gName, DateTime gDate)
        // Set default to false
        bool returnBool = false;
        SqlDataSourceEvents.SelectCommand = "SELECT ID, StartTime, EndTime, EventName, UserID, Details FROM EventTable WHERE (DATEPART(day, StartTime) = DATEPART(day, '" + gDate.ToString() + "')) AND (UserID='" + gName + "')";

        for (int i = 0; i < GridViewEvents.Rows.Count; i++)
            if (DateTime.Parse(GridViewEvents.Rows[i].Cells[0].Text) == gDate)
                if (GridViewEvents.Rows[i].Cells[2].Text == gName)
                    returnBool = true;
        // Return SqlDataSourceEvents to original state
        SqlDataSourceEvents.SelectCommand = "SELECT ID, StartTime, EndTime, EventName, UserID, Details FROM EventTable WHERE (DATEPART(month, StartTime) = 

How to avoid that BCP.exe insert stops when duplicate record exist?

I’m a migration consultant at Infor (Infor and Microsoft have a partnership) and we use in case the target database is SQL Server the bcp.exe to upload the data from old Baan-systems and legacy-systems into our core product “Infor ERP LN”.

The big, big problem with the bcp.exe is that loading stops as soon as a duplicate record exists. Is it possible to extend the bcp.exe to be able to load in append- and conventional mode like Oracle sql loader?
This is the big advantage of the Oracle High performance loader (sqlldr) where you can load the data in Conventional mode which creates the records per row!

I also heard that the bcp.exe will be replaced in future by another utility. We really hope this new utility don’t stop by each duplicate! Maybe you can provide me with more details about the new utility?

Many thanks in advance!

Using a CompareValidator to check input is a valid date

The CompareValidator can do more than just compare two controls. You can also compare it against several of the main .net data types such as Date, Integer, Double and Currency.

To do this you would set Operator="DataTypeCheck" and instead of setting the ControlToCompare or ValueToCompare attributes as you normally would you use the Type="Date" (or any of the data types I have listed above).

Check All with JQuery and a Asp.Net GridView

Display a Grid on the screen with a checkbox in each row. At the bottom of the page have "Check All" button.

Typically if I need to do anything interesting I use a template column. So my GridView will look like the one below (most other columns removed for readability). The only interesting point to note is the CssClass="ApprovalCheckBox" in the CheckBox ItemTemplate.

GridView inline Master/Detail record display

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

check box control


Hi ,

I have a three check box in my web form ,i need to choose only one check box, if i choose one check box

another 2 check box automatically unchecked

can i use jquery for check box

I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time
