Populate An Unbound Column In Bound Datagridview Using .net?
Jun 13, 2012I am populating a datagridview from a datatable and that is working fine. I wish to add some calculated columns from data in the datatable. At first, I did this by adding these to the table, but that makes it difficult to update the Access database. These lines are commented out.Right now, AWt and DOF are not working. The values are there when I step through (lines 85-87), but the values are not put in the grid. The value of NWt is placed in the grid as it should be.Lines 236 through 254 set up the new unbound columns. 85-87 should populate them.

VS 2008 Bound DataRepeater With Unbound CheckBox Control?
Mar 28, 2011I'm seriously about to abandon this DataRepeater. I don't want to. I want greater design control than the DataGridView. I've played with various Events for days and have settled on the CheckBox.CheckChanged Event.
What I'm trying to accomplish: My Bound DataRepeater has an UnBound CheckBox in each DataRepeaterItem.When the user 'Checks' the CheckBox, I want to change the value of a NumericUpDown Control to the value of a hidden, Bound Label.
[Code]...
This causes other, seemingly random, DataRepeaterItems (Rows) to also become Checked and thus it's NumericUpDown value to change.Am I going about this from the wrong angle? Can't see the forest for the trees?

VS 2010 - "Rows Cannot Be Programmatically Added To The DataGridView's Rows Collection When The Control Is Data-bound"
Sep 1, 2011Can 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.

Mar 15, 2011I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console.

Drag And Drop Rows Bound Datagridview?

I don't mind using two buttons (up and down) to do it either. But I am not able to figure out a way to do it.

Copy Excel Rows In Program?
Apr 28, 2011I'm using the excel object model (importing namespace Microsoft.Office.Interop.Excel) to open an Excel.Application object in my code, then open a workbook, worksheet, etc. What I'm doing is ridiculously simple: I'm opening two worksheet objects; one is already populated with data and another one is empty and is supposed to be populated with some rows from the first worksheet. If some conditions, regarding cells in the first worksheet, are not met, then I want to copy the entire row in the second worksheet, at the first available row. I have an integer counter, initialized at 1, which indexes the first empty row in the output worksheet this counter is obviously incremented every time I insert a row at outputSheet.Rows(counter).
Every solution I've Googled either uses VBA (I'm looking for a solution based on VB.NET) or is not compatible with .NET framework 3.5 (I'm receiving exceptions at runtime). I'm guessing I'm not using the Range object correctly or something; in any case, what's the simplest way to do this? I really don't want to open an OLEDB connection to my excel file: this is too complicated for the simple row copying mechanism I'm trying to implement.[code]...
