Event Handler For Dynamically Created Controls?
Mar 4, 2012I would like to ask a question with DataGridView event handling.The event I am going to handle is the double-clicking of a cell in a DataGridView:If the DataGridView's are statically drawn on the form at design time, then it is easy to assign to each of them an even handler by double clicking the corresponding event in the properties panel.
Private
SubDataGridView1_CellDoubleClick(sender
AsSystem.Object,
[code]....
So basically I have handle to all of the DataGridView's. Is there a way to create a common event handler on this basis?
Event Handlers For Dynamically Created Controls
Aug 2, 2009I'm not seeing anything about event handlers for dynamically created controls.. and I could have sworn I had once before. I did see one post about the topic, but it was just replied by asking for some posted code, so as in a preemptive move..
Private Sub buttonCreate()
Dim newbutton As New Button
newbutton.Height = 39
[CODE]...
Here's what I'm trying...
Private Sub newButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newButton.Click
End Sub
Here's the errors I recieve...QuoteHandles clause requires a WithEvents variable defined in the containing type or one of its base types

Event Handler For Dynamically Created Listbox Control?
Jan 24, 2012I am passing some values from a Gridview Update Click event to a popup ASP.net page that dynamically builds a series of textboxes in a Placeholder based on the number of sentences that are found in a specific cell of the Grid Row selected.The boxes that are built represent each sentence found in the cell of the selected row. Each sentence is presented for translation, where user enters data into a 2nd dynamically generated textbox.This all works great.Now I have a Listbox beside the 2nd textbox, which sometimes has 1 or more variables that need to placed into the translated sentence. I have set up a Hover menu over the listbox so that I can select the variable and insert it at the end of the sentence in the 2nd textbox. My problem is generating the click event on the dynamically created Listbox. Something like....
Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = TextBox1.Text & ListBox1.SelectedValue

On Change Event For Dynamically Created Drop Dowlist
Apr 21, 2009I have a website where the user requires to add and remove Headlines from the main page.
The headlines are stored in a database with a column titled 'Display' (true or false) which decides if the headlines appear. I want the user to have the ability to add or remove headlines from the main page, so have created another page which creates a table of all headlines along with a drop down list containing 'Enable' and 'disable'. I want these drop down lists to work by when the user changes the value in the drop down list the database will be updated. Only I cant find how to give the drop down lists an on change event.
VS 2010 : Event Handler For Dynamically Created Controls?
Sep 14, 2011I have to create controls for inputting info to create people objects in the program, because I don't know how many people they are going to input, I have a button that they can press to add more fields.
I need to add a doubleclick event for these dynamic controls (text boxes), how can I create an event for them if they haven't been created yet. Also, as far as I know you cant make a variable part of an object name while declaring it. I need to do something like
Dim dynamicText & (Append variable counter each time a box is made)As New TextBox
dynamicText &variable counter. Name = "TimeTextBox"
dynamicText.Text = "SdgsdG"
dynamicText.Location = New System.Drawing.Point(100, 100)
[code].....
Also is there a way to like copy and paste a group of controls via code instead of having to code each individual one like if I had to do a text box along with a combo box and a lable all at once, can I throw it into something so I only have to recreate the container?
Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?
Dec 5, 2011I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

View 2 RepliesDynamically Created TextBox-Control?
Sep 15, 2011I have a strange behavior with a dynamically created TextBox-Control. The control is created in the handler of the Load-event of a dialog-form like this:
[Code]...
Now the situation is, that in most cases it works fine. But a few of my customers report that the TextBox not appears on their dialog - it's not there! That's all, nothing more to say.hints or reports about known pitfalls with dynamically created controls which could explain this (sometimes) strange behavior and how I could fix it (I have to create this control dynamically due to some reasons).
BTW: The program is built with Visual Basic 2005. And the customers with trouble are spread about the OS's (XP, Vista, 7).
Getting Information From A Dynamically Created Textbox?
Jul 11, 2011A user can select a few chec box options, then clicks OK.A new tabpage with a textbox and two buttons is created and added to my form, the textbox can be seen as a sort of 'receipt', and one button is a close button, which deletes that tab, the other button is an edit button.When the user selects edit, I would like the selection page to open up, checking, (through a couple of If conditions, whether a text is contained in the text box), then if a certain text is found in the box, a corresponding checkbox on my form is checked.
So basically, my problem is trying to check the text from a textbox which doesnt exist until after my form is loaded... I need someway to reference this new text box, not forgetting there may be many tabs at one stage.I tried a method in which each new texbox was added to a list, then when the edit button was clicked, it checked the tab index and checked the corresponding textbox, but this would only work for the first tab/textbox and caused issues with the close button, perhaps when the edit button is pressed, VB checks my selected tab, and somehow finds the textbox which is on that tab.

.net - ASP.NET: OnChange On Dynamically Created Textbox Inside UpdatePanel Fires Twice
Dec 15, 2011I'm creating a number of textboxes, all calling a function during the onchange event to update their value to the database. These boxes are dynamically created in the backend because the data changes based on specific criteria that can be changed on the page. Here's the creation of the boxes:
Dim t as TableRow
tC = New TableCell
Dim txtBox As New TextBox
[Code]....
When I enter a number into the Textbox, the event fires as expected, but it fires twice.
Dynamically Created Event - Button To Simply Set A String Variable Equal To The Clicked Buttons Text
Mar 14, 2009I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?

VS 2008 Accessing Dynamically Created Picturebox?
Mar 22, 2012For school and other reasons, i am making an application in which the user can draw tile based backgrounds, to then turn into long line of code , i think called CSV , which can then be used in programs such as flash, to draw a tile based background. I am currently making a flash game, and dont really like the other tile array making programs out there.
For instance, code such as [1,0,1],[0,1,0],[1,0,1] with the correct code would generate a 3x3 tile background with an X shape.Anyway, at the moment i am currently stuck.I have code up and running which generates a 2 dimensional background out of pictureboxes randomly, however thats as far as i got, i dont know how to access the pictureboxes created.
What i have right now is two variables, gridX and gridY, which determine the amount of tiles placed in a for loop. These variables would be used to determine the size of multidimensional arrays that store the tile data, and determine the map size.i intended each image to be clickable, so that its picture would change from black to white when clicked
When clicked, the tile would switch between two images, to represent two different tiles. at the same time, a value in an array created with the tile, would change from 1 to 0.Then when its time to make the code, i simply use a for loop to spit out the array in the way i want.
I understand that i could perhaps create a class for the pictureboxes, but i dont know how to, since ive never dealt with them, and i dont understand any of the guides and tuts.how to use a class so that i could add and change the properties of multiple dynamically created pictureboxes, but also change the value of an array created with the picturebox, when clicked?
i need all of this to be done however without adding or including any additional libraries or anything to visual basic as it will be graded on school computers.
