currently i am working on a project in which i am using datagridview control. if I enter key value in cell than remaining data of that particular row fetch automatically from data base. how? how to delete as row in datagridview? how to update a row in datagridview?
View 5 RepliesI have a GridView that is tied to an EntityDataSource. Most columns are normal bound columns, but two are itemtemplates. When I attempt a delete on one of the rows I receive the following message:
"A property named 'Building1.building_name' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source."
I'm not sure how it is possible that this isn't available, since it displays the element just fine when I'm just viewing - it just throws the error when I attempt deleting a row?

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.
View 2 RepliesI need to perform a calculation based on the idea that the user will select the operation, which is in this label lblOperation. The two numbers, num1 and num2, come from lblNum1 and lblNum 2, which are randomly generated. How can I change the statement to say lblCorrect.Text = the value of num1 and num2 where the operation performed is whatever operation the user chooses from lblOperation.Text? This is what I have so far:
'btnSubmit instructions
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code]....
Instead of always adding the num1 and num2 I want the operation to be between the two numbers and the answer to be printed in lblCorrect.

I have a problem with this code.It loops all records in tables SAP_CC and ORCL_CC and matches all records where amounts are equal in both tables. The problem arises when I need to update the tables.I need to update a column on tables SAP_CC and ORCL_CC, setting the records as matched and also to create new records on the CC_RECONCILED table.
In the If ¦ End If the line .Open("CC_RECONCILED") throws the COM Exception:Operation is not allowed when the object is open. I cannot close rsl¦Is there a way of achieving my goal?
I've got results in a loop format from a XML file, I want to either insert them into my SQL database or update them if they are already there. My question is more around lodgic, do I have to
1. Get each item.
2. Do a search for it and see if it's in there.
3. If not add
4. If so update
Or is there a quicker way because with 200 records at a time, search then update/insert will slow down the process.

I'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.
I need some help in using a stored procedure in my case below: I have a table with a single XML column which takes in fields VoucherCode and Quantity, the data in SQL xml column looks like this:

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAdd.Click
