VS 2008 Getting String On Textbox Inside User Define Control?
Jan 19, 2010
I have created a User Control (UC) where user type the information it needed and save it ti MS SQL Database and also have created a User Control dedicated for it's button, since my main form has split container and has two panels, one for UC which contain the button only and the other one for my Main UC where user enter the information.I created a Module that contain the function on adding the data type in UC Main to the database.
[Code]...
on My UCButton named "Save" I just call the function AddUserInformation. But the problem is the variable where it bind to the ucUserControlMain textbox remains Blank, When i query the my database table, only the UserInforID and the DateAdded has been updated and the other column remains blank where the variable get it in the UCMain Textbox...
I have an application that allows the user to define text in a rich textbox. I would like to give the user the ability to define text for one or more languages. I don't think this will be a problem using the rich textbox as it allows for unicode characters and DBCS (please let me know if this is incorrect). My question is, I display this text throughout the app in other controls as well, such as a listbox, label, etc. by acquiring the RTF's Text property (plain text). Are there problems with other controls displaying unicode/DBCS characters? I realize that I may have to toggle the font of the control in question depending on the language (I will allow the user to specify a default font per language).
I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
I have created a user control and am able to add it to a page with out any problems, but how to I reference a control that is inside of the user control For example if I have a text box inside the user control and want to set the text property through code or get the text property, How can I reference the control inside the user control. I have tried a few different things but nothing seems to work when I type the usercontrolname.control.property I just get an error.
I think the short answer is you can't, but there has to be someway to make it happen. I want to make a list of items, that then have a list of items within them, nesting only one level.[code]...
Is there a way to define an array inside of the sub call parentheses?
Private Sub sub_name(byval sString, arrString) sub_name("Some Text", array.{"","",""})
What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.
I've made a user control and have added some internal labels inside it. In the User control class I'm trying to handle the mouse events so that: When the mouse enters the User-Control the background of the User-Control turns white - using MouseEnter event. When the mouse leaves the User-Control the background of the User-Control turns grey - using MouseLeave event. However as soon as I move the mouse over the internal labels it triggers the MouseLeave event. I don't want it to do that, because the mouse hasn't left the bounds of the User-Control! So, how do I get it to not trigger the MouseLeave event when the mouse is still internal to the User-Control?
i have the following problam: i have a user control which i want to raise an event from to the page that is using that user control (its a button)anyway my problem started when i wanted to put this user control inside a repeater instead of another button (regular asp:button)anyway i needed to support CommandArgument so that page can use the button,so i created a property:
Private m_CommandArgument As Object Public Property CommandArgument() As Object Get[code].....
so after i press the button and the postback happen my raised event dosnt have a value..where should this property be saved in order for it to have a value after postback? view state? how do i add to the the viewstate automaticly?
i want to set the CommandTarget property of menu item to the TextControl which is written in win form or just tell me any way which can execute the command lets say cut copy paste on the control which is written in win form user control and added to xaml through WindowsFormsHost
I've created a private sub which enables me to move to the next object when I press enter in the textbox or any input controls... What I want to do is to create a universal sub procedure for moving to next object. this is my code
I have UC that inherits a textbox. It is meant to only accept numeric values. I want to be able to add a property to give the end user the choice of setting the FORETCOLOR to another color other than that which they have chosen for the normal FORETCOLOR settings. Is there some line of code that will allow me to access FONTCOLOR dialog box when a user clicks the FORECOLORNEGATIVE property setting in the Properties settings?
I'd like to create a user-defined data type in VB.NET but don't know how to do it.Take an example.......say there's a variable to control the action of a timer control. The possible actions would be "no action", "run timer", and "stop timer."I could do this with an integer (e.g. 0=no action, 1=run timer, 2=stop timer), but I'd rather create a data type so that the options are more explanatory than a simple integer. Like so....
Private Timer_Action as MyDataType Timer_Action=MyDataType.RunTimer
I need to define sql command to retieve user name, password and balance from database.. I've added two forms and it works proberly but suddenly after entering the username and the password, this error occurs "Vshost-clr2.exe has stop working" and gives me two options whether to debug or to close program.
My freeware program launches 50 freeware programs and provides a guide for PC maintenance and health. As mentioned in another post, my program was reviewed on Sofpedia. One thing the Reviewer criticized was the fact that my program requires the user to install these 50 programs in the default locations (usually C:Program Filesx). The reviewer thinks it would be best if the user can install to any location he/she desires and my program be able to point to the proper location when launching the application.
I have a string and I want to see if inside that string I have the word Peter. [Code] This does not work, It still says Yes when I have Not in the textbox. How can I do this correctly?
I need to be able to allow the user to type in a file name and folder location into a textbox then when you run the program (that the client makes) it will create a program in that location. The problem is that when it runs it says that access to the folder is denied. I Think it is because it is that there is a file with the same name as the folder. The input as of now i have it as "C:\Another Folder\Filename.exe" but when I do this it creates two folders (Another folder and Filename.exe)... I thought that you could do it using substrings and last index of but either i wasn't doing it correctly or it doesn't work. I want to be able to do this from one textbox.
dim rootname as string = textbox1 dim exename as string dim location as string dim thepath as string
Im wonder how i can create a textfile from the text inside in the textbox. I have already begun with the code, but i get an error.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim output As String = Nothing output = TextBox2.Text output = GetFileContents("C: est.txt") End Sub
I've been struggling with something I imagined would be simple. My aim is to create a TextBox or Label with in a GroupBox using VB.net, yes I could use the Toolbox/Common Controls to do this easily, but it's a pain when planning on making more than just one or two of them
Here's my current coding to create the actual text box.
[Code]...
All that works perfectly, but how would I allow it to show up within a GroupBox?
as seen in picture I have in "TextBox1" some numbers and I would like to have a detailed information on "TextBox2" (marked with red) when I pressed the "Process" button about them. In other words, I want the application to tell me how many numbers in total are inside "TextBox 1" and also to tell me if there are some duplicated numbers if it finds some of course?
I make a user control with textbox. When user press enter and textbox doesn't have any text then a search form open. Search a data and select some think and return to main form where my textbox control insert. I write a code below :
If txtIsbn.Text = "" And e.KeyCode = Keys.Enter Then Frm_Book_Search.FormLoad = True Frm_Book_Search.ShowDialog(Me)
[CODE]...
But problem is that when Frm_Book_Search close and it must be focus in textbox but it not happend. when user close the frm_Book_Search form then not focus my application another software if open at that time it will be focus that software. if there is not open any software then it is not any problem it will be focus my application in my textbox. how can i write code to focus current form after close frm_Book_Search form.
In order to take advantage of the spell checking ability of WPF textboxes, I have added one to a user control (with the use of elementhost). This user control is used in various window forms. My current problem is trying to handle keyup events from this textbox but the windows form is unable to "get" any event from the control. I can access the properties of the textbox just fine (i.e. text, length, etc.) but keyboard events don't seem to work.I have found, however, that the following will bring back events from the WPF textbox:
Public Class MyUserControl Private _elementHost As New ElementHost Private _wpfTextbox As New System.Windows.Controls.Textbox
[code].....
The user control is now able to do something after the PreviewKeyUp event is fired in the WPF textbox. Now, I'm not completely sure how to have the window form containing this user control to work with this.
I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?
InvoiceAdd.vb:
' Instantiate objects of the various database interaction classes. Private mCustomer As New Customers Private mItem As New Items
