Adding Column To Datagridview And Bind It
Feb 5, 2012
I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?

I would like to bind different queries for a long set of columns in datagridview that has been set already during the formload, e.g:
With dgvGrid
.Columns(0).Name = "Dept Code"
.Columns(1).Name = "Emp ID"[code]....
there are still more of it. The data needed for those columns is coming from a different table.

I'm working on VB .NET 2008.
Target: Bind dynamic datasource in a cell of a Windows.Forms.DataGridView depending on the selection in previous column. The grid must have 7 columns. If the selection on comboboxcolumn 2 or 4 is done, the datasource of comboboxcolumns 3 and 5 mus change using a query with previous selection as parameter.
In a first try to develop this functionality i've tried to use Telerik.WinControls.UI.RadGridView control. I've created a customized celltemplate with a combobox in order to have different datasource for each cell on the same column. All worked fine but seems to be some kind of bug in RadGridView, because when the combobox is presenting the list, after selection the list continued showing, doesn't dissapears as expected.
Ok, after several days of fight with RadGridView, I give up, and I tried to use same strategy but using Windows.Forms.DataGridView. I've created two classes one inherited from DataGridViewComboboxCell and other from ComboBoxColumn, in order to insert my own combbox or have the chance to have access directly to the combobox values. But the combobox showed is the default combobox not my own combobox.
how can I create a custom comboboxcell but using my own combo, and having access from outside to this combo?

I've used the following code, taken from here, to create my own custom column for datagridview, so that I can now have images and text in the same cell:
[Code]...
It works very well, except that the image that I use is right at the edges of the cell. I'd like to give it a small margin. How can I do this?

I am using a DataBindingSource to connect a DataTable to a DataGridView. Everything was working fine until I added a ComboBoxColumn
Dim ReasonColumnIndex As Integer = dgvData.Columns("Reason").Index
Dim ReasonCombo As New DataGridViewComboBoxColumn
With ReasonCombo
.Name = "Reason"
.Items.Add("BREAK")

I am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.

Problem: Calling a method which uses a cell's value from a DataBound DataGridView. Works as desired without adding an image column.When I add the image column, the method attempts to use the value from column 1 instead of column 2, as the code in the 2nd method below ("findSign") states:

I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding

But I'm having a problem with showing the right info in a gridview.
Basically I've got a maintenance tool for an application. And I want to make it multi language.
This is a check for the language:
'setting the column name where to get the text resource from
Dim comment As String = "comment"
If (licentie.getlanguage() = "NL") Then
[Code]....
So far this works. But in my template I've got the following code in the gridview:
<asp:Label ID="LabelType" runat="server" Text='<%# Bind("Comment") %>' />
How do I set the column 'comment_NL' when the language is set 'NL' in the bind?

I'm trying to display the serial number of the 'recipient' you selected in a textbox but I get this error:
System.ArgumentException: Cannot bind to the property or column RecipientSNo on the DataSource.
I did this to another textbox with a different query (same codes, just changed the column name from 'recipient' to 'issuer') just to debug and it works! I tried it again to the 'recipient' but it still doesn;t work.My code:
query("SELECT RecipientSNo FROM Recipient WHERE CONCAT(FirstName, ' ', MI, '. ', LastName) = '" & ReceiverName.Text & "';")
Try
adapter = New MySqlDataAdapter(CommandText, ServerString)
table = New DataTable
[code]....
I just coped this code and changed the textbox and column names and it did not work already.. What seems to be the problem? I double checked my table and column names already.

it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)

I have the following code on a form:
Public Sub Init(ByVal SelectedItems As List(Of Cheque))
Items = New BindingList(Of Cheque)(SelectedItems )
BindingSource1.DataSource = Items
[code]....
This code gets called like so:
...
fmEdit.Init(myList)
fmEdit.Show()
All variables are populated etc, it seems to go through the DataBindings.Add ok but when the form appears I get the error about unable to bind to a property or column called Id. I tried replacing the DataBindings.Add code to use the BindingSource1 instead of Items but I get a similar error.The names of the properties in the class match that of the name in the Databindings.Add code.
UPDATE: Here is my class:
Public Class Cheque
Public Id As String
Public Status As Byte

When I try to use the following line of code:

I get the following exception:
EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember
details I am connecting to an Access database and using .net 3.5 and writing the code in VB. In this database I have a table named Sites with a column named Site and when I try to use the line of code above I get the exception noted. I was under the impression that I could explicitly name the column that I need to use in my control (combo box).

How can we databind a datagridview to some of the My.Settings (user scoped) properties so the user can edit the values? This must be to a datagridview. I know we can bind to My.Settings in a form with textboxes and so on, but in this case we just want it as list of editable strings in a datagridview.
Of course some My.Settings entries can have different datatypes which complicates matters but generally we're only working with strings and booleans. Also, let's assume the user understands that he must enter the string "true" to set a boolean to true. No checkbox column needed. Here's what we are using (and it works), just looking for a better, leaner way: [Code]
