View 1 RepliesBind A Tree Control To A Data Source?
Feb 26, 2009I need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?

Bind The Properties Of A Control To A DataTable Object?
Feb 8, 2011What 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 :

--> MyLabel Class :
Public Class MyLabel
Inherits Label

DataGridView To Bind Or Not To Bind?
Sep 2, 2010I'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
Bind Combobox To Datatable And Object Property Causing Duplicate Bindings
Aug 19, 2011I'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 Bound To A Datatable Setting Its Datasource Property To The Datatable
May 20, 2011I 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
How To Use A Datatable As Source
Sep 1, 2010I have a datatable in memory (a flat file, no primary key or relation to other table) and I wish to make a pivot table in Excel out of it.

View 1 RepliesDatatable Column Value - Adds An Arraylist To It As The Data Source?
Oct 6, 2010I am struggling with a simple datatable issue. The following takes a data table that is on the form and adds an arraylist to it as the data source. The data that shows up in the datatable is the length of the value of the element in the arrayList.
test.Add("cjdsnthegtrk")
test.Add("cjdsk")
test.Add("cjdsk")[code]....
How do I control what is displayed in the columns? What I am ultimately trying to do is have a datatable that the operator can edit and the changes reflect in the underlying data structure.

View 13 RepliesBest Way To Bind My.Settings To A Datagridview
May 17, 2011How 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]
Bind DataGridView With 2 Tables?
Mar 8, 2010I have a datagridview who's datasource is a BindingSource. The problem that I need to resolve is that the DGV has 6 columns, 5 of which come from the same database table, while the other column comes from another database table. Is there anyway of configuring the BindingSource that will make it contain all 6 columns?
The same grid in Part 1 works in the way that when a user selects a row, textboxes and comboboxes are populated with the DGV Row of data in order for the data to be modified. When the user makes any changes, this modified data needs to update the DGV row or BindingSource. How do I associate the changed values back to the BindingSource or the DGV?
