I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count
If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then
lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."
I have a detail view form consist of five fields my 1st field is jobnumber which is primary key i want to do that when user by mistake enter the duplicate jobnumber error occur that this is already used how can i do this ?
View 1 RepliesI have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?
Using vb.net/asp.net 2005 and sql server mgmt studio 2005.
I am querying sql server db and returning unique records, no duplicates when I return the records in sql server mgmt studio.
However when I bind the dataTable that I return it is showing multiple duplicates, meaning I see each record appear 8 times in the gridview, has anyone seen this or know what I'm doing wrong?

Iam using the Gridview control for inserting the records in Database i placed the controls in TemplateField tag like Textboxes and DropDownlist but when page executes nothing is displaying in the control Is there any way to get it work or i must have to define the datasource for the Gridview Control????
<asp:TemplateField ...>
<ItemTemplate>
<asp:DropDownList ..../>
And more textboxes like the above way but there is no Bound Field because iam going to insert the record in DB while placing the controls in Gridview Control
I have a gridview with 3 columns dropdown, textbox1, textbox2.
On pageload my gridview loads with one row i.e dropdown with databinding done with some values, empty Textbox, empty textbox2
i have add new row button
clicking on that i will get new row in gridview with dropdown with databinding done with some values, empty Textbox, empty textbox2
I have save button to save the gridview rows into DB.
Question:
I should not allow user to select same dropdown value in two different rows. How can i validate that.
I used this example [URL] but add this in gridview
<asp:GridView ID="GridView1" Width="300" runat="server" AutoGenerateColumns="false" RowStyle-BackColor="#A1DCF2"
HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White">

Using checkboxes, can the row of record(s) be inserted into a database? I am populating a Gridview. Done. A checkbox field has been added, when the user selects one or more rows, a submit button (which is not working) needs to inserting those records into a table. The insert statment will work outside of the page but is not working using the scenario I jut described. Is this task as I have outlined doable?
View 13 RepliesOn 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.
i have code to update multiple rows in a gridview. What I want is that if the row value is = 1 in the database then the row is checked otherwise it's not. I've put some pseudo code in below to illustrate what I want to achieve.

i am using an ImageButton with onClick Event above a profile on a footballer.
On Click event, a logged in user on the site can save the footballer to a Junction table called FavouriteFootballer that has
a GUID UserId and FootballerId GUID as Primary Keys.
The problems is I need to warn the user if they already have the Footballer Stored as a favourite in the database

I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

I have a DetailsView control that accepts two different fields to be populated. I need one of them to be masked so that whilst something can be entered, no-one can see what is actually being keyed?
View 6 RepliesI have a listview that I automatically generated from a database table, enabling editing and inserting on the listview and the EntityDataSource that runs it.
I started customizing the listview templates so that I didn't have to see some of the fields (they're unnecessary from the standpoint of the form), and have alternately tried removing or hiding the unwanted fields. This pretty much patently results in me not being able to insert new records, although updating seems to work just fine. There are no error messages.
I then tried using InsertParameters in the datasource, but that didn't really help either.
In the codebehind I have an onInserting handler that should fill in some of the hidden/removed fields before the record goes to the database.
I've tried pretty much everything I can think of, and even my colleagues are kind of stumped. Why can't I insert records into this table/listview?

Here's the next instalment of my asp.net data access nightmare!
I've got a listview on my page, and when I run the page it correctly displays the data that it should. However, when I add data into the empty new record and hit the 'Insert' button the page posts back but the record isn't inserted. Annoyingly, I don't get any error!
The listview's datasource has an INSERT command and insert parameters specified. The button seems to be triggering the listview's insert method because the ItemInserting event fires.
With no error message to go on I'm struggling to figure out what the problem is. I have a feeling it's something to do with the makeup of the page. The listview in question is nested within an Accordion control and the listview's data source isn't set until runtime, when it's done in the ItemDataBound event of the Accordion control. As I say, though, it does RETRIEVE data correctly, it's just the inserting that's a problem.
I created a new, blank page with just this listview on it using the same code but not nesting it within any other control and hardcoding the datasource instead of setting it at runtime and that works perfectly, so I'm confident that my INSERT command, insert parameters and so forth are correct.
I've tried to get my listview to break, deliberately leaving out insert parameters and so forth just so it'll give me an error message but it never does! It's as if the insert isn't taking place at all, except that because the ItemInserting even takes place I'm assuming that it is.
This FormView is inserting two records instead of just one.

I am beginner of asp.net and c#Currently i doing appointment website and need suggestions/ ideas. I have create a simple web form with Calender Control as picture below enable users to select date and time. At the calender control, i have set that users can only select tuesday and thursday every month using DayRender. After that i put a DropDownList to display the time.Next step, i want to store the data into database, for example UserA make appointment on Date 21 September 2010, Time 1100 and make it unavailable for other bookings. When UserB makes appointment on same Date and Time, it will display information that the slot is booked/unavailable. To implement this, what approach should i take?

I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?
I've looked all over for this problem but can't find anything that works. I have a details view bound to a database that when a user enters their details and clicks insert it will store the data and then send them to another page. I have tried response.redirect but that does nothing. I am using c# btw.

as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
