Binding Controls To A Settings File?
May 9, 2012
I want to be able to control several groups of settings independently of each other. I'd originally used My.Settings, but it was too much work to manually rollback some settings whilst saving others.
I thought my solution was to use multiple settings files, and I've had moments where this seemed to work, but I whatever success I have had is periodic and temporary.
Currently I have two settings files in the root of the project; In code, I can access the settings OK, but in many cases I want to bind individual settings to controls. This should be straight-forward, and I recall it working when I used the single, built-in settings file.
However, when I use the two new settings files it doesn't work. In the Formatting & Advanced Binding dialog, I select Add New Project Data Source, I browse into my project, then into the root namespace, and then I see my forms/classes/settings files. When I select the two settings files, and click OK, the dialog is dismissed without me being able to select an individual setting to bind the control to.
When I enable Project > Show All Files, I can see that the binding has been created; I have two .datasource files under My Project > Datasources.
Is there some reason why I shouldn't be able to bind to these settings files? If not, why can I not access them the the data-binding dialogs?
Plan B is to create an object to act as an intermediary between the controls and the settings files, but I'd rather avoid this if I can.

I have three radiobuttons in a groupbox. When they are not bound to application settings, they behave normally.After binding each of their checked properties to application settings, the following happens: I have to click an uncheckedradiobutton two times to have it checked. After the first click, all three are unchecked.

If I load a datatable, and then set a listbox properties pointing to it, I get the right data, e.g.:
[code]...
I get System.Data.DataRowView instead of my actual data.I don't understand how the databinding is actual happening, and how I refresh my the data in the control when the data changes.

I have a form that with a list of text boxes. My target is simply binding these controls to an XML file so that whenever the file contents are changed externally, the text box values change dynamically. I will have an external application edit the XML file and overwrite the existing one.

I have the following datagrid:
<asp:DataGrid runat="server" ID="gastosReembolsables" ShowFooter="True" AutoGenerateColumns="False">
<AlternatingItemStyle CssClass="DATAitem2"></AlternatingItemStyle>
<ItemStyle CssClass="DATAitem1"></ItemStyle>
<HeaderStyle CssClass="DATAheader"></HeaderStyle>
<FooterStyle CssClass="DATAitem1"></FooterStyle>
<Columns>
[Code]...
all bindings work except the ones in the validation controls for the itemtemplate of the last column (they are passed as text to the web page). Why is this happening? is it even possible to do what I'm trying to do?

I have yet to find a "nice" way to do two way databinding in .Net. The one thing I don't like for example in the present asp.net two way databinding is doing the binding in the aspx page is no compile time checking, ie:
<asp:TextBox ID="TitleTextBox"
runat="server" Text='<%# Bind("Title_oops_spelled_wrong") %>'>
I would like to have something like this:
Class Binder
Public Sub BindControl(ctl As Control, objectProperty As ???????)
'// Add ctl and objectProperty to a collection
End Sub
What I don't know is possible is, how to receive the objectProperty in my example; I want to receive a reference (ie: a pointer) to the property, so later, via this reference, I can either read from or write to the property.
Can this somehow be done with delegates perhaps??
UPDATE: Note, I want to add the control reference to a binding collection, this collection would then be used for binding and unbinding.

1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...
2. I'm not actually saving them when I think I am.
Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?

I am using Visual Basic Express 2010.
I have programmatically set up a Datagrid and binding navigator etc., but I cannot get the movenext, movelast buttons to actually hook up to the Data on the Datagrid.
I have tried to set up an addhandler for the BindingNavigatorMoveLastcontrol, and although I can get the BindingNavigatorMoveLastcontrol to display my messagebox
WHICH IT DISPLAYS TWICE FOR SOME REASON I cannot get it to actually move around the Dataset, or any of the other navigation properties for that matter.

Ive added a service ref and then thats about as far as ive got, everything i try to do to call data from the service seems wrong. How do you go about this

I have a windows form that I bind to a datatable via a binding source. The binding is done in code at run time. Eg;Me.txtCode.DataBindings.Add(New System.Windows.Forms.Binding("Text", bsForm, "ToolCode", True)) (bsForm is the binding source)This works well except if the form control is hidden (I have a couple controls on the form that hold Record ID and Version numbers that the user doesn't need to see). Databinding doesn't seem to work reliably for hidden controls.

I need to add rows to a DataSet using databound controls in VB.net. I've set up the data bindings themselves, they're bound the the correct controls, and the BindingSource uses the correct DataSet. The DataSet is filled from the DataAdapter correctly, and the binding source works, as the navigation controls all work fine. How do I use the controls to add new data to the DataSet? I guess there must be some kind of end-edit involved which would enable me to insert, update and delete records in the DataSet (as you would use with DataGridViews)

I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.

I have SQLdb column elements from one table that are selected from another table. This is achieved through the use of binding a combobox to the selectable entries and applying that entries ID to the initiating table column When I add multiple combo boxes, for multiple columns, the data selected propagates across all the combo boxes I have. They all use the same binding source. It seems to me the only way out of this is to create a bunch of binding sources, essentially one for each control. I have tested this and it appears to work, but is there another, less cluttered way of ensuring that the comboboxes, while bound to the same binding source, are not bound to one another?

I have a series of check boxes and text boxes that are paired up together. 3 check boxes and three text boxes. Right now I have code in each of the Check boxes changed event as follows:
If UseSuffix_CheckBox.Checked = True Then
SuffixValue_TextBox.Enabled = True
SuffixValue_Label.Enabled = True
[Code]....
What I would like is to have one public routine (Function or Sub) that gets handed in the the control name/ref that just got clicked and then perform the functions listed in the above statement. Basically I want to have one routine that all the check box changed event points and acts on that check box and its paired text boxes and labels. I know it can be done just not sure how to pass the control that was clicked by the user to the sub.

I saw that you can also use a "Settings File" (Add new Item)to add your settings instead of the application settings. But I can't seem to write any values to the file. Someone with experience with the "Settings1.settings"?

I have an MDI form on which I have placed a ToolStripContainer. I have set the BackColor of the toolstripcontainer.contentpanel to an ApplicationsSettings property binding for BackColor. At design time the background colour of the contentpanel reflects the colour in the saved Applications Settings. However at run-time the background colour of the content panel is not the colour that has been saved in the applications settings (in this case DarkSeaGreen). It continues to display the colour from the current

I am creating an application for a company and this CD will be distributed to hundreds of people. Many users will have different computer screen size and different screen settings such as their resolution set to 1024 x 728 and their monitor size 17" inches.
I noticed when I loaded the application on a different computer with different settings the application was to big for the screen and did not work. I notice that lot of other programs from microsoft resize their controls and text but never knew how they did it. How can I resize the form and control according to the user's setting.

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False
