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

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

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

Show Bit Column As A Checkbox Column In Unbound Datagridview

May 14, 2010

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp

Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.

I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.

how can i change this in code at runtime

Sorting A Unbound Datagridview Column

Sep 8, 2011

I have an unbound datagridview that I populate with data. When the user clicks on the column head the datagridview is sorted - which is fine for alphabetic fields but I have a column that contains numeric fields and goes from -100 to +100. This is sorted incorrectly by the number (all the 1s first then all the 2s and so on, ignoring the minus sign). How do I get it to sort my column numerically?

Unbound Datagridview Column Not Retaining Values?

Jan 10, 2011

I have a DataGridView bound to a binding source. I have also, however, added an unbound column in which I plan on putting numbers calculated from the bound columns. The problem is, Any time I edit my unbound column (on any row), the value doesn't stay. If I programmatically edit the values, they never show up. If I type in the cell, then upon hitting enter or clicking outside of the cell, whatever I typed disappears.

IDE :: Unbound Button Column In DataGridView Control Placement?

Jan 3, 2010

I am trying to put an unbound button in the last column in a DataGridView control and it appears way, way off to the right when I run the app. I have to scroll all the way to the right to get to the buttons and then manually resize them to show up the way I want them to. I am using the Edit Columns feature found in the Smart Tag of the control. It works ok when I place them anywhere else in the columns! It only messes up when I try to place them at the end of the columns.

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.

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]

Preventing Column Auto Sort After Editing A Bound DataGridView

I've got a DataGridView that has a DataTable as it's Datasource. Whenever I sort a column and then edit a cell, after editing the column, the column autosorts so the recently edited cell is no longer in the viewable area. Is there any way to prevent this auto sort from happening and only sort when I click on the columns?

VS 2008 Bound DataRepeater With Unbound CheckBox Control?

Mar 28, 2011

I'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?

Re Order Column Order In A Data Bound DataGridView?

Apr 17, 2010

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2

But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?

I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
