Javascript Events :: Dynamically Resize The Multiline Textbox?
Dec 22, 2010
I am working on a site it is in VB.net, I need to createa mutliline text box. I am able to increase the height of the textbox as number of characters increases using java script,however when page get refreshed or loaded again then textbox size comes back to the default height.
I have a MDI form with different controls, two of they are multiline textboxes, and by default the form opens in normal state. Once opened, if I maximize the form all the controls location and size are as I wants (using the anchor property). And now comes the estrange error, if I have opened other form maximized, and then I open the first mentioned form, the multiline textboxes location is wrong, they are upper than the correct location.
Note 1: If I change multiline to false, all works fine.Note 2: The textboxes location is in the bottom of the form and the anchor is left, bottom and right.I try different possibilities and search information in the web without results.
In my application i need to resize the TableLayoutpanel dynamically..when i resize this control automatically resize rows and columns equal size. I wrote below code it's working but it's working very slow.
Private Sub tbpanel_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Try Dim iColCount As Integer = tbpanel.ColumnCount
In an .aspx page with a VB.NET codebehind I am using an IFRAME which would be created inside the repeater control. Since I want to resize the IFRAME based on the content within the page I have been using the resize function obtained from here on the IFRAME onload as shown below.
I have a multiline textbox that has wordwrap set to True I am assigning each line of the textbox to a string Lets say I typed this into the textbox without pressing enter and it just wordwrapped to the next line Visual Programming is fun it would assign "Visual Programming is fun" to the first string however, what i want it to do is assign "Visual Programming is" to the first string and "fun" to the second string.....now if i would have pressed enter after "is" then it would have done what I wanted it to do, but if i dont press enter and just let it word wrap it does not do what i want it to do...
I came across an issue which I see has been discussed a few times, but there doesn't seem to be a defintive answer to the question.How can the child windows in Silverlight 4 be dynamically sized to fit within the size of the current browser window?The problem is on smaller displays where the browser window may be smaller than what the child window was originally developed for.What occurs is the OK and Cancel buttons are off the screen and cannot be scrolled to via the browser.You can duplicate this problem by simply shrinking the height of a browser window manually while the child window is displayed.The controls will disappear and there is no way to get to them.This is pretty much simulates what users with smaller monitors see.So the question is how can you set up a child window to dynamically size itself so it users can still interact with it?
I need to let the end user move and resize objects (like a textbox or button). There are several examples that demonstrate this in VB, but not in VB Express 2008, based upon VB.net.It looks like earlier you needed to access Windows API, but these calls does not work in VB.net. I understand that these call are replaced by "native" .net calls, but I cannot find any that does the job.
A typial example from old VB is:
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
I need to resize Rows and columns dynamically in TableLayoutpanel..I achive this but it's not perfectly come in some times.. My requirement is how we are resize the rows and columns of TableLayoutpanel at design time..Same like i need to implement at Runtime.If i resize any row or column only That perticuler item only resizing ..
I have a form with a textbox to enter a number and a button called "Create". When a user enters a number and clicks create the form gets populated with the number of buttons entered in the textbox and the title of the buttons are labeled by consecutive numbers. For example if you enter 5 the form will populate with 5 buttons labeled button1, button2, ...button5. When you click on these newly created buttons a messagebox will popup stating the buttons name. Basically I need to know how to create events and populate them with code I guess dynamically.
Here's the situation: I have a variable number of dynamically created update panels on my page, so I thought I would write one method which handles all of the loading for each one.
My Updatepanel creation looks something like this: Dim newUpdp As New UpdatePanel newUpdatep.ChildrenAsTriggers = False
I've created a VB.Net ClassLibrary with a UserControl in it. I can load it from an HTML page and call the methods that I created. This works as expected. I've tried several examples for how to raise an event from the VB code to the js caller, and none of them seem to work (I'm using IE7).
I am trying to dynamically resize labels and position each subsequent label a perdetermined distance from the end of the label that was just generated. My code looks like this:
My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:
If datareader("Who_Second").ToString = lbl_Your_Position.Text Then Dim b1 As New ImageButton b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString
[code]....
What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:
Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Dim MyDate As Date Dim QCC_Q_ID, Position As String
[code]....
Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?
I'm developing a website in visual studio 2008 using (asp.net/vb)I have to allow registered users to build pages and add controls that are already defined by the same userMy problem is how to build this page dynamically?In other words, I'd like to make like any CMS (e.g. Joomla). CMSs allow us to make new pages and add our controls then save them..
I have code that reads file paths froma text file into my application for an mru list on my apps main menu. The menuitems are added programatically from each line of the text file. How can i attach events to these menu items?
I have made an click event for a button which creates buttons dynamically and I added events to the dynamic buttons by using addhandler but it says it the button is not declared. Here is the code for dynamic buttons:
Private Sub MenuBtnNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuBtnNew.Click
I need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!
I have a multiline textbox that while a file is read in some data is echo'ed out onto the textbox. Is is possible to programatically scroll the object down to the bottom? Changing everything over to a combobox and then changing the selected index would essentially do what I want, but the user needs to select/copy a bunch of lines.
I'm trying to make a textbox at runtime, Dim t as Control
t = New Textbox t.Multiline = True t.Size = New Size(300,120) Form1.Controls.Add(t)
I found out that you can only size a textbox when Multiline is set true. And that's the problem. When I use t.Mutiline = true I get the error " 'multiline' is not a member of 'system.windows.forms.control' "
I've searched the internet for hours without result.
I have a number of user control dynamically added to a page, and user interaction with these dynamically added user controls need to be handled by the control's parent. Is this what is referred to as "event bubbling"?How do I do that in VB?
I've got a class where I pass in a panel reference and in that panel I'm then required to draw multiple other panels that represent my objects. The issue is that when I go to bind dynamically click events to these panels I don't have reference to the Form of which I want to popup on the click event.
The reason for this structure is so that I can redraw my class dynamically and reattach certain events to each object.
Is there any way to do this without moving my classes logic outside of the Assembly or is there any way to attach my click event to a piece of code logic to a sub in my WinForm?
I am trying to create a program, where the user click a button and this will add a custom control and then drag and drop them on the form.
What I want to be able to do is add multiple controls (by clicking this button) and for them all to have the same events. So basically they can add as many as they like of this control and then click on it and drag it anywhere.I know in vb6 there was the use of the control index but I am not sure how to do this in Visual Studio 2005?
