Changing Text Of Custom Control Based On Text Of Another Custom Control
Jan 11, 2010
I am using custom textboxes and I need to be able to set the Text on txb1 based on the Text of txb2. I have simplied my code to the following:
Public Class customtextbox
Inherits TextBox
Public Event ControlReset()
[Code]....
So, when txb1 looses focus, if its Text is "fried", then it sets off txb2's ProcessAlert function. I had tried to change the value of txb2 Text in ProcessAlert function, but didnt work, so I tried to get it to raise an event instead, which then tries to set the Text property. However I still cant set txb2's Text property. The Text property seems to be set for the duration of the "life" of the Event handler. When I step through the forms controls within the Event handler, the changed Text value is there, but not outside of the Event handler.

I have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.

I want to create an custom control just like an Autosuggest control for my windows application. When I type, it should show a grid for the suggestion have the typed value.for an example if I want to search a student "ashish". As soon as I type A in textbox, it should show its First Name, Last name, Address, its image and some other info into a grid or grid like format beneath that control. All those info will come from Database.

I have a Custom Groupbox that overrides the OnPaint event to do some custom drawing, backgrounds, etc. The problem I have is that when I use it in an application and want to draw text on the control, it gets drawn first, then immediately afterwards the OnPaint from the control gets called and draws on top of the text. Is there any way to get the text drawn after the control's OnPaint?

I am making a custom button control and am having some difficulty with my Text property. Anything I type in only stays while the form designer window is open. When I close the form designer and reopen it, my Text property resets to "". Also if I run the program, it loses the value entered at design time.
I also have an Image property for my control which is working just fine.
Here's some of my code:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Windows.Forms

When I put a label on a form, the Text property in the designer can be expanded to a multi-line edit box. (This is in VS2005.)
Is there a way to get that type of edit box on a custom String property of a usercontrol?

I want to create a custom control that has a cursor like a regular text box, I tried using a line and a timer that makes the line 'Blink', but that wasn't too reliable because I had to change the location and background in the timer... I guess I could do it, but I wanted to ask my question here.
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.

So, I'm working on a custom LitBox that accepts custom items. needed the item collection to be more than just strings, I needed to be able to store avalue to display in the listbox and an associated value (Property: Text) that holds an index value (Property: Tag) of DataTable I'm working with.I have created the new item (iListBoxItem) and the collection (iListBoxItemCollection) and have modified everything so that I can do normal Collection type methods (Add, InsertAt, RemoveAt, etc) to this collection.
vb
Imports System.ComponentModel
Public Class iListBox

I have created several simply custom controls and I used them in my app. Now, I changed the background color in a custom control class, because I wanted an other color for this type of control. But in my app, the background of this controls didn't change. Why? I assume, I don't need to place again this controls on each forms to get the new background color, or do I? If yes, this is very stupid in my opinion.

How could I create custom commands based on text? Like, say I have a textbox, and in the textbox is this: "say Hi". When I press the "Execute" button, it will do this: "MsgBox("Hi")"... Kind of like a custom scripting language... I want my application to support scripting, but I want the syntax to be simple... How do I go about doing this?

I have a user control that checks if a certain query string and session value are present then returns a boolean based on that, if it's true I want to set the master page. The page is throwing an Object reference exception when it tries to call the method EditUser1.UserAuthorization(). Why is this happening? I imagine that the method doesn't exist at that point in the stack. Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit

Can a custom control NEW Sub be the only one that executes when Inheriting from an existing control please?I am Inheriting from TabControl and I do not want the base New Sub called, is this possible?In other words, I do not want TabPage1 and TabPage2 to be added.A Form has an Activated Sub which runs once a Form is activated.It is a pity that Microsoft have not got such a method in the baseControl Class otherwise I could have used it within a custom TabControl.
Public Class Form1
Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
End Sub

We have a ASP.NET web application written in VB.NET where we build content programmatically during the Init event.We make extensive use of user controls, building them on the fly, and I now want to start including SilverLight content.Is there an easy way of embedding a SilverLight application in a control, and then instantiating the whole thing in code, in the same way as you'd programmatically add ordinary ASP.NET controls to a page?The SilverLight component itself works fine when added to a page using the <object> tag but I really want to be able to reuse it elsewhere in code.Since I'm expecting use of SilverLight to increase in our application, and the asp:Silverlight control seems now to be deprecated, I'm looking for an alternative way of wrapping the content.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I have a form with about 48 checkboxes.I have a public sub that reads a webpage, parse the text of that site to get the values that correspond to these checkboxes.For example: one of the lines would be: "Exterior = 255", or "Street = 0".I do have check boxes that called "Exterior" and "Street". the question is how I can get my sub to address the appropriate control so I can set its "checked" property based on the text read.

how I can control the tool tip popup or make calls to the text that displays based on a integer value. I'm wanting it to display a text based on a interger value inside an if statment for a picture box. So if the ingteger = 1 then tooltip.text = "" else tooltip.text = "" but that is not the correct syntax.
