VS 2005 Databinding With Labels?
Nov 9, 2009I have a form where I bind the Text property of several labels to various columns in a datatable. A couple of the labels get updated as a result of user selections, so for those labels I set the UpdateMode of the databinding object to 'OnPropertyChanged'. When the user makes their selections, I change the text property of the label - and indeed I can see where the text property changes.
However, when it comes time to save the data, I do a GetChanges on the datatable looking for rows that are Modified - and I get back nothing. I've tried explicitly calling the WriteValue method of the databinding object after I update the text property of the label. Still nothing.

VS 2005 - Perfect Databinding With ComboBox And Textbox
Oct 7, 2009What wrong with my databinding? How to correct the perfect binding with combobox and texbox.. When I select Projectname the other are changing except the email... Why the email is not changing?

daemails = New OleDbDataAdapter

VS 2005 : Stop Combobox Event Firing During Databinding?
Mar 29, 2010I have the following code that populates a combobox:
With Me.ClassSelector
.DataSource = DataAccess.Utilities.ReferenceDataUtils.GetLookupTableData("Category_code_classes")
.DisplayMember = "Category_text"
.ValueMember = "category_class"
End With
However, the SelectedValueChanged event fires once when I set the datasource and again when I set the valuemember. In both instances there is a selected value, although that value was not selected by any user action, but rather because of the loading of the combo box.I don't think there's a 'SurpressEventFiring' property for the combobox, so how to you check to see if the change in the selection was a result of user action and not data loading?Perhaps I'm populating my combobox wrong?
edit: changed 'displaymember' to 'valuemember'

Updating Two Tables Using A Databinding From Within A Form?
May 16, 2011I have three tables Tasks, Notes & CallTypes Each item in Tasks and Notes has a relationship to CallTypes and my form edits work fine. However: Notes only belong to tasks, and when i update the note record we will need to change the CallType for the Task as well as for the Note and they could both be different.
I have the Notes working fine, but i cannot update the tasks. I have created a databindng on to a form from the datasources window. All the notes fields are ok and are working I then add the calltype field from the tasks, draged from the data sources window (i dont want all of the tasks fields, just the calltype).
The code does not through up errors, but when i save the form it only updates the notes and not the tasks.

View 4 RepliesWindows Form - Missing Something Simple - Object Databinding?
Nov 26, 2011I am missing something simple. I know how to bind asp.net datagrids and webforms, but this is my first time trying to bind to an object list of T in a windows form. (I am use to using datasets with datatables and im trying to get away from doing that).I have a simple object list that gets populated on the form load. However if I click a button to add a dummy record the datagridview does not display the new record added. The bindingNavigator (if clicked nextrecord) and "debug stops" all show that the new record I just added to the object list is there.
Even adding the datasource object in the watch list shows the new records are there. They are just not displaying.
I cannot seem to figure out as to why the new record is not being displayed in the datagridview when I can see the record got clearly added to the datasource.

View 2 RepliesVS 2005 Copy Form Within VB 2005 Project?
Oct 12, 2009I'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.

VS 2005 Child Form Remain Enabled While Modal Form Displayed?
Oct 28, 2010I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.
View 7 RepliesForms :: [2005] Form-To-Form ComboBox Item Defaulting?
Jan 18, 2011I have been creating a call management application and I am having a problem with something that I have spent weeks on trying to get working and nothing I try is working for me. My application is an MDI application written in VB.NET 2005 Professional, using .NET Framework 2.0. It uses a back end database using Microsoft SQL Server 2005.When the MDI application launches, a form is displayed to the end user asking for phone number (MaskedTextBox) and a partner name. The partner names are within a ComboBox.
When the end user types in the phone number and selects a value from within the ComboBox, s/he clicks on the start button. This then opens a second form. The phone number from the MaskedTextBox is to default in a second MaskedTextBox (this I am able to get working without issue.) The partner name selected from the ComboBox is to default on the second ComboBox. This is the part where I have been working on it for weeks and not able to get it to function.
The second form has many ComboBoxes, all of which pull down items from a particular table within the database. Some of them are editable and some are not. The ones that are editable are also auto complete Suggest/Append on the ListItems.I wrote a sub to handle the population of these ComboBoxes and also to handle if they are editable or not. All of this is working. However, my main issue is that I can't get the value on the second form to default to what ever was selected on the first form. I do not get any errors but regardless of what I do, the second form always stays as the first item in the list regardless.
The code I am using is as follows:
<CLSCompliant(True)> Public Sub PopulateDropDownListFromDB(ByVal cboName As Elegant.Ui.ComboBox, _
ByVal TableName As String, ByVal ColumnName As String, _
ByVal UseAutoComplete As Boolean, _
ByVal UseSQLDistinct As Boolean)

[2005] How To Use Bindingsources From Main Form On Dialog Form?
Mar 2, 2009My project has a single dataset with about 6 datatables. Each of those datatables has a TableAdapater and a Bindingsource on the main form (due to various databound controls).
Now, I want to have a second form for adding a new record. If I bind the controls to the datasource it creates new TableAdapaters and new Bindingsources on that form. I was wondering if it's possible to simply use the ones from the main form instead like this

Databinding 101 - How To Do It In .Net
Sep 8, 2011I have a list of strings. How do I bind it to a listbox so that the listbox updates as the data of the list changes? I'm using vb.net.I've tried this so far. I've manage to display the data, but not change it:
Public Class Form1
Private mycountries As New List(Of String)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
I've also tried this:
ListBox1.DataBindings.Add("items", mycountries, "Item")
But items is readonly, so it doesn't work.Also, if I want to bind the enabled property of a button to a boolean, how can I do that?I've tried this but I don't know what to add for the last parameter.
Dim b As Boolean = True
Button3.DataBindings.Add("Enabled", b, "")
Asp.net Databinding Without FormView?
May 15, 2011I have an ASP.NET page with a Wizard control containing several steps and about 80 form fields. The data is collected and inserted to a database from the code behind page. I need to set this form up so you can not only insert, but edit a record as well. So I want to databind the fields. I'd rather not use a FormView because then I would have to revise my existing code, since you can't access controls inside a FormView directly. Is there a way to databind the fields without using a FormView?
View 1 RepliesC# - WPF Databinding Converter .NET?
Aug 9, 2011I have a button that i basically want to either show or hide it based on if a certain string has a value or not. I create the buttons in code so i was trying to used databindings with a converter but i can't seem to get the converter on the binding after the value changes. I'm not sure if I'm going after this correctly or not... Here is what i have for creating the button and the binding and the converter. "sFileLocation" is a string inside my class "QuestionsFile". This works for initialization but its just when the value of the string changes, this binding doesn't see the change and doesn't run the converter and all that for me...
Dim btn2 As New Button
Dim b2 As New Binding("sFileLocation")
b2.Mode = BindingMode.TwoWay
[code]....
The thing I don't understand too is that the binding works fine if i just binding the property to the Button.Content. So the property is updating correctly when it gets changed, and the buttons content changes accordingly.
