Add An Unbound Column To A Bound DGV (data Grid View)?

Feb 1, 2011

I have seen multiple examples on google and on these forums about how to do this. It seems there are two approaches:

1 - Add the column directly to the DGV and populate it

2 - Add the column to the underlying dataset

Populate An Unbound Column In Bound Datagridview Using .net?

Jun 13, 2012

I 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.

Public Class LotGrid
Dim LotsTab As New DataTable
Dim PurTab As New DataTable
Dim SalTab As New DataTable

Unbound Populating Data Grid

Jan 27, 2009

tried quite a bit of iterations, not a local admin so i dont want to even bother using the data connection wizard, want to do all of this with unbound controls only the harder way for learning purposes and also so i dont have to keep logging in as local admin and create data sources in the future. Cant really seem to get the table to fill, it appears always with blank fields, and tried many different ways. Currently using vb. net 2005 msvs.[code]

DB/Reporting :: Displaying DataGridView Text Column In A Mixed Bound/Unbound DataGridView?

Mar 15, 2011

I 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. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

DataGridView - Display Two Column Editable Grid Not Bound To A Database

Oct 7, 2011

I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:

1. When editing a cell, it adds a new row: [url] How can I prevent this?

2. I don't like the grey background and would like the grid to fill the whole space, right and below.

BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]

Data Grid View Header Grid Color

Jan 14, 2010

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

Unbound Data Column In A Datagridview Moves Position?

Mar 10, 2010

I have a form and in that form is a datagridview listing information from a table in a database. The datagrid is setup as read only and the user is unable to move the columns around. The purpose of the datagrid is to allow the user to select entire records and press a menu button that does some action on them. To make it easier to use the very first column in an unbound data column that I fill with a number representing the row count so 1,2,3,4.... this makes it easier for the user to count how many rows he has selected.

The problem is that the unbound column moves to the last column in the datagrid at random times.This only happens in development not after the application has been deployed. Its annoying because lets say I go in to add a label or change a menu item on the form that has nothing to do with the datagrid I have to make sure that the unbound column hasn't moved.Has anyone else had this problem mixing bound and unbound columns in a datagridview.

Datagrid View Two Columns Bound To Same Data?

Aug 7, 2010

I have a datagridview control that will be used to allow the user to input records. The control uses a combobox column to select a type of service. There is a rate associated with the type of service that I then want to display in the grid. The user then enters a quantity and the last column mulitplies the rate and quantity to get a total. I have the combobox , quantity and total columns figured out but I don't know how to get the rate column to automatically be selected when the type of service is selected. Below is the code.... sets up the datagridview

Dim dv As New DataView(LookupManager.Lookups.LookupServiceType)
Dim Column1 As New DataGridViewComboBoxColumn

.net - Selecting A Row(s) With Multiple Columns From A Grid View And Add Them To Another Grid View?

May 6, 2009

I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

Data Grid View As Log Display

Mar 8, 2011

I need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.

These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.

I also need the ability to clear all events (rows).

I guess the first question is if the data grid view is the best control in VB to use.

Is there a good example on using the data grid on how to add data to the data grid view one row at a time?
