View 1 RepliesI have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound.
how to add Rows programmatically to the DataGridView's rows collection when the control is data-bound? here is my code but i got error as "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound? "
[Code]...
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.

I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".

View 5 RepliesI have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...
I'm using the TableAdapter to Insert rows into a database, when I use execute from the Query Builder, the line gets entered into the database, when I enter it via Form button, it doesn't get entered to the database using the same commands.

I have a word document with multiple tables. How can I specify in VB.NET to find a specific table and insert rows only into that one? I've successfully implemented the Find&Replace in the document... but the problem is that I have an unknown number of things that must be added into the table based on the data I'm querying from my database. So there is no simple solution as far as putting placeholders in the table and using the find and replace function.
