Javascript - Enter Key - Loginview
Jun 11, 2010
I was given the following pseudo code in order to get the form that has focus and only allow the form I want to be submitted: [Code]
How would I do this for VB.net because VB.net doesn't accept System.Windows.Forms.KeyPressEventArgs. I also wanted to add that I can't have multiple forms on my website as it disrupts the loginview. So my 2 separate 'forms' are really just a loginview and then an asp:textbox and asp:button by themselves without a form.

I have a web page where I want users to enter ratings for a particular software. I have got this working fine. What I am after now, is that users need to be logged in to enter ratings. I have dragged the loginview control onto the page and dragged all the other controls/datasources into this view. However now I am getting alot of squiggly lines regarding my controls not being declared. I have been told that I need to use the FindControl method. However I'm not sure on how to use it in my instance as I have a dropdownlist involved.
The controls are called: LoginView1, DropDownList1, TextBox1 and Button1 for the insert.
Any proper declarations so I can insert data into my database. Here is the code as it stands outside of the loginview:
Sub doInsert(ByVal Source
As
Object,
ByVal E
As EventArgs)
Handles Button1.Click

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

I have to store, in 2 cookie dictionary/keyed cookie, a user's preference for hiding certain sections of each form on the app. It would appear that IE7 has reached some limit for the number or size of the cookie in javascript. I mean that the cookies are only inaccessible on the client-side js, but can be read just fine in our asp.net/vb code-behind.
The functions that need to read the value of these cookies must be on client side because I can't run a postback everytime the function needs to update the cookie. How should I go about getting and setting the cookie without triggering postback? I thought about storing the value of the cookie onload in a textbox, but I don't know when I would read it back and update the cookie.

I have a grid column, of which, row X is hidden. I want to pick the values of each column's row x, perform some calculations at client side and display it in row y(through client side code). I am not able to pick values from hidden field in client side. Is there a way I can put those values in a client side array using javascript code, and use it for my calculations. Also when page posts back, the array should get updated with latest values.

In a VB.net app, I have several checkboxes created with regular ASP controls, i.e.asp:CheckBox ID="cb3" runat="server" Checked="true" />I'm trying to implement a "Select all/none" functionality but I'm having a few problems. The Javascript is not changing the state of the checkboxes in Internet Explorer (v9). I tried debugging with IE's dev tools and the checkboxes are definitely getting their checked property set to true. (Also tried setting to "checked".) Here is the JS:
function setCheckboxes( state )
{
var inputs = document.getElementsByTagName("input");

I'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]
