Bind The Properties Of A Control To A DataTable Object?

Feb 8, 2011

What I want to achieve is to Bind just some of the properties of a Control to a DataTable object.Let's say I have a Label on the Form : "MyLabel1".MyLabel is a Class that inherits from Label and adds a property "ID", an Integer, to the base class.

I want to Bind .Left and .Top properties of MyLabel1 to a DataRow in my DataTable, and I want to see them updating, everytime I change MyLabel1 location on Form. I put description and full code, so everyone can test it in minutes :

I have :

--> A Form, with a DataGridView "DGV" : The DGV is for showing at real time the desired properties of the controls I want to bind ( in this case, just one control : MyLabel1 ).

--> MyLabel Class :
Public Class MyLabel
Inherits Label
Private m_id As Integer

Bind Combobox To Datatable And Object Property Causing Duplicate Bindings

Aug 19, 2011

I'm trying to populate the list of a combobox by binding it to a datatable. Also, I want the selected value of the combobox to be bound to an object property so that when the selected value changes, it's automatically updating the object. However it's causing an error at runtime: "This causes two bindings in the collection to bind to the same property.

Parameter name: binding" I thought binding the dropdown list to a datatable and the selected value to an object were different properties but obviously I'm not getting it right.

Code:

Private Sub PopulateSiteSelect()
With Me.PlanSiteSelect
If _Plan.PlanID <> Nothing And _User.UserID <> Nothing And _Plan.Category <> Nothing Then

DataGridView To Bind Or Not To Bind?

Sep 2, 2010

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

Datagridview Bound To A Datatable Setting Its Datasource Property To The Datatable

May 20, 2011

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)

now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings

Get Subset DataTable From Main DataTable, But Preserve Primary Key & RowErrors?

Apr 16, 2012

I came across a problem with using a BindingSource as my DataGridViews.DataSource. Whenever I applied a filter to a column in the BindingSource and the user makes changes that don't match the column filter the DataGridViewRows would automatically disappear. A similar thing would happen when applying a Sort to a column. If the user made any changes the DridGirdViewRows would automatically sort causing rows to be moved around. This was not ideal for my application and there isn't anyway to stop this from happening with the BindingSource.

To correct this issue I have to use subsets of data. I use a DataView to apply the filter and sort to the main DataTable, which creates the subset DataTable.The problem is when I use the DataView.ToTable method I loose the Primary Key and RowError information. So I have to reapply this information everytime the user filters or sorts the DataGridView.Is there a better way to get a subset DataTable?[code]...
