Winforms - Usercontrol With Dockstyle Fill Not Correct Size During Form Load
May 25, 2011
My main form has two panels, left docked and right docked. The right side panel has two child panels with top dock and bottom dock settings. The usercontrol is added to the right side top panel. My usercontrol has a panel and a label. The panel is anchored on all 4 sides, the label is anchored on all except the bottom. At runtime I create this usercontrol and set it to dockstyle=fill and then I add it to my top right panel.
With everything set to "fill" I expect that when I add my usercontrol to the panel it will take on the appropriate width and height and pass that info to the child controls (labels) inside of my usercontrol. My problem is that this stretching of the size does not happen when I create my objects during the Load event on my usercontrol. Even though initializecomponent has ran for the usercontrol the panel inside of it (4 corners anchored) has not taken the x/y values of the available space. As a result my usercontrol shows up about 50% of the width I want.

I've got an MDI form with child forms that I'd like to refactor to a single form with a tab control containing child controls, in order to move away from MDI clunkiness. When looking at converting the child forms into child controls (or usercontrols), I do see that I'd lose the FormClosing event, which some of the child forms use.
I can override Dispose to handle some of the functionality, but in some cases I'd like to cancel the closing event. Also, I'd like this event to be called before the control is closed even when the form it's on isn't closing, so wiring the control to the form's closing event isn't an option.

I have a simple windows Forms application where in I have a usercontrol called "MyControl" derived from PictureBox.
In this MyControl, I have the following code :
Sub New()
MyBase.New()
Me.BackgroundImage = My.Resources.MyImage 'This is a project resource image
End Sub
Now when I drag and drop this MyControl into a form, I get the image and also those stuff. But the problem is that the BackgroundImage is being copied into the Form's local .resx file.So when I look into the form.designer file, I find the following :
Me.MyControl1.BackgroundImage = CType(resources.GetObject("MyControl1.BackgroundImage"), System.Drawing.Image)
This is a problem and also when I try to change the image in the control, it does not get reflected in the form's control instance.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)

In my form.load event, there is a bindingsource.fill event.After the .fill, there are two or three other lines of code that query the newly filled tablemanager. The code gets the number of total records and displays that number on the form.Here is the problem ....When the .fill statement is executed, control reverts to the form and any statement AFTER the .fill event is not executed.I have tried to stick the remaining lines of code into some other form event with little success. These three lines of code only need to run once.Does anyone have a suggestion as to where to stick these lines?
Private Sub SCDBEditWindow_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'SCDBDataDataSet.StampCollection' table. You can move, or remove it, as needed.

When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo()
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb")
con.Open()
cmd = New OleDbCommand("Select * from BankAccount", con)

Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....

I followed the last post about dgvs and have been trying to get my dgvs to have alternate colored lines on form load. In both apps I am working on I am using dgvs to display certain things. I do not like the look of a blank dgv on a form. When I tried to add blank colored lines to my dgv, it did work, but when I loaded the dgv with a dataset, it pushed my columns to the right and I had to add scroll bars to see my data.

I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?

I have an WinForms app that requires Name/Address data in lots of places, so I decided it would be a good idea to create a User Control. So far, so good. My problem is this: Let's say that my UserControl presents 2 text boxes (txtFName and txtLName) and txtLName is mandatory. What I want to do is put the validation code, e.g.: Code:If txtLName.Text.Length = 0 ThenMessagebox.Show("Enter a last name")End If

I'm trying to save some layouts from DevExpress Grid Controls so that users can change the layouts and reload them in at a later use of the control.
My question is this for speed issues I am loading the control via a user control inside of a form. Now my problem is I am creating the control by adding an instance of the control to a panel control inside of a tabbed group control when the tab is made visible and then clearing the control when the control is hidden.
If ClaimsGridPanelControl.Visible = True Then
ClaimsGridPanelControl.Controls.Add(New RXClaimsGridControl(ClaimsBindingSource))
Else
ClaimsGridPanelControl.Controls.Clear()
End If
So inside of the RxClaimGridControl I need to call a SaveLayout method when I am clearing the control. But there is no event, at least that I can find, that triggers when a usercontrol is removed/closed/hidden.
My thoughts for handling the .Clear() would be to raise an event in the parent control and then to handle that event inside of the user control.
Is there some event that I am missing in regards to the removal/closing/hiding of a user control, or is there a better way to do this.

[URL]its a free hoster, so you have to wait 10 seconds.First here's the steps to replicate, then I'll explain what the problem is:
(1) Create a System.Windows.Forms.UserControl and add a button to the bottom-right hand corner. Leave the button anchor as default (top-left). Add some more buttons dotted around so that you can see that they scale correctly.
(2) Add the UserControl to a form in the construtor, after the InitializeComponent call.
(3) Run the form.
(4) Increase the form font size some way (eg click a form button).
All the controls within the usercontrol scale perfectly but the usercontrol itself doesn't. It's width and height are increased by way too much. Look at the margin now between the button at the bottom-right hand corner and the usercontrol.To correct the problem, the usercontrol must be added before the InitializeComponent call.If it wasn't possible for me to add the usercontrol before InitializeComponent, is there any way for me to correct the scaling?

I have a UserControl, with a TextBox and a databound property - Value.Value can be any object such as a Color, Array, Font etc.Any time the text changes, the property Value is changed as long as it is valid.Looking at the msdn article: How to: Apply the PropertyNameChanged Pattern , it says I should use the PropertyNameChanged Event patternfrom the control side.Now, If I have DataSourceUpdateMode = OnValidate, then I don't even need to apply this pattern. If, say. my Value property is bound to a colour field in a business object, then after I type red, in the textbox and tab to another field, then any other fields on the form, that bind to the same colour field, are updated immediately.

I am working on a wizard form framework that will allow me easily create wizard forms.I have a WizardForm form that has a panel on it. My plan is to dynamically load UserControls into this panel on the form.Each UserControl that is loaded onto the form panel must implement certain properties (allowNavigateNext, AllowNAvigate previous etc.). So I have created an interface to enforce that contract so that any custom user control can be used in the wizard as long as it implements that Interface. So far so good. created my first user control. I implemented the interface. All was good.I went to do the second user control and I realized that this second user control would have the EXACT SAME implementation of the interface as the first User Control. So...I thought...aha...duplicated code...how can I get rid of that.

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.

I built a specialized userControl using VB2008 (on XP 32-bit) to embed in HTML (not ASP!) and compiled it, pointing to x86 CPUs. I added the necessary keys to the registry (see attachment) to declare a classId in a HTML 'object' tag. This scheme works OK on all 32-bit OS I could put my hands on, but fails to load on 64-bit: I could test only on XP and Win 2003. No error message and Fiddler does not even know something happened... I installed VS2008 on the XP 64-bit machine and ported the code to a fresh userControl (to check the code). I got the userControl running on this workstation without any trouble. I copied this new DLL on another workstation and added the necessary keys to the register, but to no avail. I checked the registry and the 'Wow64' keys are there allright. As a check (and to provide you with a 'working' example), I:
- built a very simple userControl on the 32-bit environment (label, textbox and button to display the text in a mMessage box),
- on the 32-bit workstation:
+ copied the file to a 'program files' folder,
