I would like to save records in my unbound datagridview to a table in my database. The datagridview was manually created during design and is not bounded to any table. After the user has filled in the rows and columns, I would like all the rows to be inserted into the table. How do I go about this?
View 11 RepliesI want to add to my site a simple table/excel-like feauture that will display some values. So, I added a gridview. I don't use Datasets or database biding at all. All I have is a small form with two entries. When the user clicks a button, I want to add some values to the datagridview control as a new row. How do I add a new record to datagridview control in VB.NET?[code]...
View 2 RepliesI have a VB project with a form where user adds/modifies the data, data are stored in SQL. On the form there are 2 tables that are linked by employee ID. When I test the process and insert a new employee record and add new comment for this new employee in DataGridView - when I save it I get an error that "Object reference is not set to an instance of an object". During more detailed debug it says that CurrentCell is set to Nothing - even that I do have values in all fields.I do set employee ID in the related table in the Grid to the value from the employee record - so all primary keys do have value and the comment is saved after all but I get an error and saved comment dissapears from the screen right after saving. When I pull the same new record again - everything is saved. What am I missing and how to avoid the error and dissapearing of the saved comment?
Also - I tried to save the new employee data in the first table first and then add comments - it didn't solve the problem. But if I add first part of information in the main table, save and close the form, then go back and add comment - it works fine. The problem is - it's not convenient for the user - they'd like to enter everything at once.

I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.

View 3 RepliesI am new to VB.net and have created a simple master detail windows form. I created a two table data set and then dropped the master table on the form as a continues form or a detail form with several text boxes to hold the data. The child form is a data grid.
test data that I have added directly to the database shows up with the proper parent child relationships on the form. I can also enter new records into the database using the parent only portion of my form.
When I attempt to enter a complete record with data in both the parent form and the child data grid I get this error. The INSERT statement conflicted with the FOREIGN KEY constraint
[Code]...
I have searched for a possible reason for this error but can not find any explanation. I have noted in earlier versions of VB.net you had to enter code to save the child record, but the VB 2010 code does not seem to use the same syntax so I assumed the UpdateAll eliminated the need for the extra code
I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.
Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.
enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.
I have an Access DB that lists customer details in a datagrid and in textboxes, when I use the edit button I can edit in the textboxes and when I click save the record is saved and shows in the datagrid. But when I exit the program I get "Syntax error in update command" Im not sure why because there are no errors in the error pane at the bottom

I have a datagridview which has columns which are bounded and unbounded. My problem is when the user enters several rows in the dgv, only the data found in last row is saved in the access table. For example, if the user enters 2 rows of data, when he clicks the save button, there are 2 rows saved in the access table but both rows contain the data of the last row in the dgv. Below is the code of the save button.

What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

can anybody please help me with my problem. I have a database and I view the data using a datagridview, the problem is I cant update my database using the datagridview properly because there is an error in my codes. I just cant understand what I should do to make it run. I know there are lots of post about updating database using the datagridview but none of them is the one I am using. Please review my codes and tell what is wrong.

The error says that "the variable @a has already been declared..." As you can see I did not use the Me.Validate etc. to update my database because I do not know how to use them and I would like to focus on using this kind of codes in my program. This is the reason why the post about datagridview here are not useful for me.
I also included an example of what is being populated in the DataGridView from the xml file/schema from the start (see very bottom), which of course I'd like to be able to add more data to it via the DataGridView and then save it back to xml.

I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.
