Exit Grid With Ctrl-TAB When Grid Is On A Tabpage (onkeydown Works When Grid Not On Tabpage)?

Jun 2, 2010

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :

[Code]...

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

UserControl MyBase.Paint - Works And Doesn't Work (Value Changed Via BackgroundWorker.ProgressChanged)

Mar 27, 2012

I have a UserControl that has a ProgressBar on it. The purpose of the UserControl is to be able to show the progress % on the ProgressBar as text. To do this it uses the MyBase.Paint event. To make it work the ProgressBar is made invisible and the UserControl is 'painted' with an image of the ProgressBar and then the text is painted on top. The UserControl has a Value property that is passed through to the ProgressBar.Value property.

I use this UserControl in two places, on a Splash form (not a standard Splash Screen) and also on the main form of the application. It works on the Splash form but not on the main form - by work I mean that changes to the ProgressBar.Value property cause the ProgressBar to show its progress. The cause appears to be that in the Splash form case the MyBase.Paint event is called as a consequence of calling Me.Refresh in the Set procedure of the UserControl.Value property, in the main form case it isn't,
i.e. Me.Refresh isn't causing MyBase.Paint to run.

The main form has two BackgroundWorker components. The first gets called (RunWorkerAsync) from Form_Load after the Splash form has been shown. The BackgroundWorker.ProgressChanged event updates the Value property of the UserControl and it works exactly as intended. The second gets called as a result of a user starting an operation and again the BackgroundWorker.ProgressChanged event updates the Value property of the UserControl but MyBase.Paint doesn't run so the ProgressBar remains resolutely static.

Any ideas why it won't respond to Me.Refresh in one case but does in the other? Happy to make any of the code avaialble but didn't want to fllod the first post with reams of it. Here's what I think are the most relevant code sections. First the UserControl

UserControl Access To Public Properties In Another UserControl?

Jun 12, 2011

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:

IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

.net - RaiseEvent From A UserControl That's Placed On A UserControl That's On A Form?

Jul 11, 2011

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.

Asp.net - Reference TextBox In One UserControl From Another UserControl

Jan 19, 2011

I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.

I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.

How do I reference a text box that is on DataEntryUC from NavSaveUC?

I have been working on the following code from NavSaveUC with no luck.

Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

Setting Usercontrol Properties Within A Usercontrol

Mar 22, 2012

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?

Code in UserControl:

Public Property DBItems() As List(Of String)
Get
Return DBItems

Data Grid View Header Grid Color

Jan 14, 2010

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

VS 2010 Load Data Into UserControl In UserControl.Load?

Sep 25, 2011

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.

DB/Reporting :: Subtotalling Grid Per Row Using Flex Grid?

Dec 26, 2008

need to have a summation field in each row of a grid in visual basic. Each row needs to calculate the remaining quantity of its row and all other rows beneath it. Thus the subtotal field in the 1st row would equal the sum of the shown quantity field for the entire grid.The next row would include its value and all those beneath it. Its subtotal value would be less than the subtotal of the row above it (by the quantity value of the 1st row). My code for the grid is very simple I just can't figure out how to add this iteration.

Net Property Grid. Is There A Way To Let The Grid Manipulate Object In Different Way

May 31, 2009

As I understood , The property grid is given an object which it can manipulate by extracting its Properties using reflections.

My problem is that I have a set of Parameters that is determined during run-time , thus I can't staticly compose a class with properties to represent this set.

I have two idea in mind to solve this problem but both are complex and will probably consume lot of time , infact i will say they are not practical under my time constraints. One is to use Reflection Emit in order to define a class dynamically and the other is to dynamiclly build a C# source file and then compile it using CodeDom.

Can Property grid behave in a different manner( other then extracting the Properties of an object using reflections ) that can suite my problem?

I want to say that the reason I went to the property grid from the begining was its ability to provide realy nice Data Retrieval UI for common types.For color you autometically get a palette , For dataTime you automatically have a nice calender. I would like to get those things automatically If possible.

[2005] VSFlexGrid 8: Create A "sub-grid" Inside Existing Grid Control?

Feb 13, 2009

I have a FlexGrid control in my Windows application that contains a row of data. The data in this row is related to even more data that won't all fit on the same row. For Example:The main data row contains Username, Last Name, First Name, Middle Name, E-mail Address, Phone Number, etcA secondary row to this might contain user permissions to certain resources, such as File Server Access, FTP Access, Remote Access, etc.Now, I can use the subtotal and outline capabilities of the VSFlexGrid to make a second row, but the column widths are still bound by those set for the main data row. Additionally, I can't put real "headers" on the supplemental data. I have to fake it by creating an additional row, setting the background color of that row to gray, putting the header strings into those fields, and then adding the next row with the actual details.

What I would like to do is create separate grids for these secondary rows and "embed" them in a blank row of the existing FlexGrid control directly under the related main data row. This would give me the ability to use a different number of columns, to format these columns independently of the "parent" FlexGrid settings, as well as put a new header row for the new grid that identifies its data.In other words, I'd like to somehow make a "child" grid that's related to a particular row of the "parent" grid (not the entire grid itself). I don't know if this is possible, and if there is another way for me to accomplish this goal, I'm all ears. However, if it IS possible, I'd love some advice on how to implement it.

.net - Selecting A Row(s) With Multiple Columns From A Grid View And Add Them To Another Grid View?

May 6, 2009

I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?
