View 3 RepliesI am currently looping through all the controls on my page and setting certain types (TextBox, CheckBox, DropDownList, etc.) to Enabled=False under certain conditions. However I notice an obvious page load increase looping like this. Is it possible to only get certain types of controls from the Page.Controls object rather than Loop through them all? Possibly with something like LINQ?
View 3 RepliesI have a master page which has a DIV with asp:Hyperlink controls functioning as the menu for the site. When I'm on a certain page if (document.title = 'Certain Page'), I want javascript which will loop through all asp:hyperlink controls on the page and hide them (i.e. set to not visible). I know I could probably do this on the server side with less effort, but I'd rather do it via javascript.

This should be very easy to do and it seems like the code below should work but it doesn't?? How can I accomplsh this with the least amount of code? FYI- this code is executed on a button click.
foreach (Control childControl in Page.Controls)
{
if (childControl is GridView)

((GridView)childControl).Visible = false;
((GridView)childControl).PageIndex = 0;
}

I'm currently trying to build a html table from the results of a sql data reader. As my table has multiple records, I want the code to loop through the reader and output the details on individual lines of the page. In ASP I have done this in the past using something like

but as I am using data readers I'm not sure what the equivalent is.
I would like to get the list of users (from db) who meets my SQL select statement, and send email for each of them.my current looks like this
Code:
Dim constguser As New SqlConnection
constguser.ConnectionString = ConfigurationManager.ConnectionStrings("xxxxxxxx").ToString
Dim email1D, email2D, userNickName, userName, rc As String
constguser.Open()
[code]....
If i run this code its only going to get the name and email of the first result found. I was wondering if there is a faster way to get all user result from the sql query, myb using a for loop?

View 1 RepliesI am building this simple quiz application using asp.net/vb.net and sql server for the database. Now what I want to happen is that when I click on submit button, it will count all the correct answers of the user based on the radio button he clicks.
I have two radio buttons and the correct answer for those two radio buttons is A, now if they click both A for those 2 radio buttons, they will get a score of two else if wrong, it won't count the incorrect answer.
Code:
Dim score As Integer = 0
If RbAnswers1.SelectedValue = "A" Then
For score = 0 To lbCorrectAnswerCount.Text.Count - 1
score += 1
Next score
If RbAnswers2.SelectedValue = "A" Then

I am new to asp development but have been around c# for a while. Basically I am trying to create a page which will pull data from a database and then for each object it creates I would like to add a user control which is built to represent that object. So basically I have tried quite a number of things to get it to work but for some reason I can't figure it out! How can I programmably add user controls and then set their properties from a 'master' page which hosts the user controls?

View 4 RepliesI wish I could go all the elements of an ASP.Net page (HTML elements) and manipulate its text property / value. How could I do that?
I've been checking, and the property this.Page.Form.Controls apparently gets all the elements, but I would only page elements that caught the event.
I'll put an example of code that I'm currently studying and trying adpater for my needs.

I am having trouble with my login form. In the current design I have a login ascx which I am trying to use for the user to login from both the home page (as a box on the left) and on the login page that I will use as part of a checkout process.My login.ascx is a partial view using straight out of the box code for simplicity...
[Code]....
What I am trying to achieve sounded rather simple until I tried to implement it. I can get the login page to come right up if I use Html.EditorForModel rather than Html.RenderPartial, but I can't use Html.EditorForModel on my main page because the main page isn't bound to a model.
What I would like is to show login form on main page. If login fails show the validation summary just like on the Login view. I could live with the user being redirected to the login view, but this wasn't what I had in mind.
I have fought a bizarre situation for days. Anytime a certain listview loaded the page went into an infinite loop of reloading. I was finally put the listview on a page with nothing else to see if I could isolate the issue.Even with only the folowing code, it continually looped on load even though it brought in the correct data every time.

Actuall i retrive one row from Database with more than 80 columns on page load. Now i need to fill these data in every control like Text-Box and Combo-Box which i have using on the Page.
My Column Name and My Id of the Textbox or combobox are same. now i need to fill the value in textbox and combobox where coumn name and textbox id are same.

(2) Column Name :- CustName CustNo Address
Values from (Dataset) :- Xyz 123 Abc.......
