[Code] i need a way to screen each employer status and mapping status before placing them in the DGV. I need to convert the numerical values to their corresponding status. 1 = Good, 2 = Non-Reporting, 3 = Under-Remitting and 4= Non-Remitting(which i already know how to do). I just don't know how to get the values being placed on the DGV. I would love to do this on oracle but i don't know how to.

I need to highlight rows in an unbound datagridview at runtime.I've tried to highlight right after adding the row using dgv.Rows.Add(row0)dgv.CurrentRow.Selected = True
This has no apperent effect as none of the rows are highlighted.How do I get various rows to highlight at runtime.
I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.

My question is: What is the best way to select multiple random rows in 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.

I 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"

I have a datagridview binded to a list of objects... I have a column named Selected containing a checkbox. When these checkboxes are checked and a button is clicked, I want those particular rows to be removed. I initially set it out to iterate through the grid's rows and RemoveAt(SelectedRowIndex) but of course when it removes an object from the List of objects at the selected row (IE Row 1, 4 and 6), the list indexes change and it fails to work properly when it goes to remove the next row since Row 4 is now row 3 in the list...? What is the best way to do this?

View 1 RepliesI am trying to insert an initial line (0) into a datagridview (named params). The program will then read each cell in that row, pass them through a function and return values be placed into the next line (1). This will continue until one of the parameters reaches some set point. The problem that I am having is that when I try to insert a new line, it appears above the initial one and not below it like I would like it to.
Here's my code so far:
Private Sub HurricaneWinds_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim init_xrange() As Double = New Double() {0.0, 0.0, 0.0, 40.0, 0.0}

View 4 RepliesI am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.
