View 2 RepliesCreate composite and custom grid control in ASP.Net 2008 or above
I need to create composite control . My control like one "div" inside that div one Gridview control.
I'm trying to create a composite control that will look like a ComboBox with a TreeView style. I'm new to this topic and I have an urgent need to create such control. I know it's not an easy task but please I need your advice to complete what I already started to build.My approach was to combined a TextBox, button and a treeview into a UserControl and make them work together as one control to achieve the control that I'm looking for (A ComboBox with a Treeview style).
So I started by creating a new windows forms control library project and I added a text box and a button as a starting point. The text box will display the name of the selected node text of the treeview and the button will show the treeview under the text box when the user click on it.
Now I'm facing tow problems with my custom control:First when I drag the custom control to a test form the resizing of the control doesn't work properly even after I used the anchor property of the text box and button controls. If I try to resize it horizontally its working find but it's not vertically.
Second I don't know how and where should I place the treeview control and how I'm going to show it exactly under the text box when the user click on the button and hide it when the user click on one of the treeview nodes.
I've search the net in order to create a custom control but nothing I find is worth looking at, The main thing I want to do is create a skinengin via DLL and import it in my vb 2010 then using or creating some sort of skin builder where I can create a full setting file which contains all the details of the customization regarding the Form(Look, Feel and the controls such as a menu), I have used Iriskin and multiple apps doing this for me and when a user installs my application they still recieve a message about buying the registered DLL file, I would like to create it completely from scratch.
View 2 RepliesI have to design a custom "log grid" control to use in another of my projects.Up front, I am new to vb.net 2008. I have used VB6 for years and I am trying to learn how to resove the differences as I go. But I need help.
This log grid contains 96 columns and 4 rows.I tried using the TableLayoutPanel and a Panel per cell but found the control to slow to paint. That's 384 discreet controls.I am now trying a usercontrol with a panel and GDI+ to create the grid. I've created a collection for the columns and a collection for the rows. So far so good. My mouse clicks raise the correct events per cell.
I now need to indicate which column the mouse is over. This is the problem. The column must be highlighted by a vertical bar from the top of the column to the bottom. It must also be transparent. I need to see the gridlines under the highlight. I've tried using region using the following code. (myRegion is declared Private MyRegion as Region at module level for persistance)

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.
When using the Property Grid and exposing a color property from an object you get this kind of interface for color selection: There are tabs for System and Web, those are fine, but the Custom tab (shown) which seems to be a subset of the standard windows color picker, seems to be hobbled. How do you create custom colors? How do you get custom colors into those white color boxes provided?

View 2 RepliesLet's say we have a composite web control with a combobox and a textbox. Is it possible to build into the control functionality such that when the text in the textbox changes, it posts back and adds the value as an option in the combobox?
I know that I could add an "onchange" handler to the textbox and make something work with Javascript, but that's not really what I'm looking to do. Is there a way to just put like:
CODE:
In the web control code and it connect to the TextChanged event of the textbox?
I have two properties ("FIRST_NAME" and "LAST_NAME") I need to access as a single property (e.g. "FULL_NAME"). Is there a way for me to add a property to my entity model that contains the combine value of FIRST_NAME and LAST_NAME?
View 1 RepliesThis should be a simple problem to fix, as it uses the same way I fixed my last problem with FooControl (below).
Basically, I want to add a derived validator I made to this composite control. It works fine but on postback it just disappears in the markup, making me think it's lost its ViewState.
I am probably doing something wrong with instantiating it, but I've tried setting only the ControlToValidate, moving things around, and nothing works.
I've provided some surrounding code to see what's working and then what's not.
Private FooControl As IFooControl
Private Validator As MyValidator
Protected Overrides Sub CreateChildControls()

I have been asked to build a custom wizard control in VB.NET for a windows forms project. It has been made very clear to me that I am not "allowed" to utilize existing wizard controls on the internet due to some obscure logic surrounding copyrights. It has also been made clear to me that we are not "allowed" to use usercontrols in the software.

This is similar to my last post but with a different purpose.I have built a custom control, but when I set the properties for it... ALL instances of that control on my page grab the exact same property. I need to be able to set the property to "abc" for one instance of the control on my page, and then set the exact same proprty to "xyz" for a different instance of the control on the same page.

I know that you can create custom formats for the DateTimePicker control, and I've googled this but is there any way that you can allow a user to only select Sunday dates in a Month with this control?
View 11 RepliesI'm trying to create a simple transparent PANEL control. I want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.

How to expose Events
I have previously used the arguments of a contentsResized event on a Winforms richtextbox to get the new size of my RTB. I am now developing a WinForms app with a custom WPF RichTextBox. My whole reason for doing this is to use the out-of-the-box spellchecker. I need my RichTextBox to expand and collapse vertically as the text is changed. The elementhost will also have to resize to allow the whole RTB to display on-screen.

Basically what I am doing is creating a custom control to allow inputs as in fractions, sub/superscripts, etc.... The TextBox Control doesn't support text in that many locations.
I had this new idea for a user control Sliding Bar/Panel. See screenshot. So I quickly whipped it up but I've got this problem that I cannot figure out why it does not work. Because I wanted to make it nice and tidy I desided to use a Class (Header) and created a TypeConverter (HeaderConverter)
Code:
Public Class HeaderConverter : Inherits ExpandableObjectConverter
Protected SortOrder() As String
Public Sub New()
SortOrder = New String() {"Text", "Depth"}
End Sub

I can get default values, but have yet to figure out how to get the selectable list.
