Web Forms :: Check If Control Exists On Master Page Or Web Form?
Nov 9, 2010
I have a function that loops through the control on my page to set attributes. This works fine, except that I only want the attributes to bet set on the controls on the content page, and not on the master page. Is it possible to check where the control resides? Or to only loop through controls on the content page?
I have a control on a master page called "panel1". I would like to access it from my Javascript on the content page. I have tried var panel1 = document.getElementById('<%= panel1 %>'); It doesn't work since it is on the Master page.
I have a master page, sub master page and content page. The master page has a form control which both masters can access by name alone:
Code: <form id="form1" runat="server">
The content page contains a contact form, with the form tags removed as they conflict with the form tags on the master.
What I want to do now is access form1 on the content page so I can change its properties for use in the contact form. I'm not sure if this is how its done in ASP? Anyway, here's how I've tried to:
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim f As Control = CType(Master.FindControl("form1"), Control) f.Action = Request.Url.ToString() f.Name = "contactForm" f.Method = IsPostBack End Sub
Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.
Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.
I have aregistration form where the user enters, among other things, a username. The form must make sure that the username is not already taken before the user submits the info.
Here's my code so far in the .aspx.cs:

I'm not sure how to call this function from the .aspx part... .
I'm trying to performa an ajax validation for e-mail address. I need to know if user is already registered so I need to check it in my database. There is similar example:
I have a site which has restricted access. Access is controlled via session variables.
There are a lot of pages to the site so I was going to check for the session variable via the page load event in my mater page. However, on certain pages I use the session variable in that pages page load event. This throws an error when the session doesn't exist, but what I want is the master page's page load to fire first.
Following is the structure of the pages in application

Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
I have a master page with a form on it. It's a people search form. When the user clicks on the search button it goes to the search results page that uses the same master page. With the code below I get the info off the master of the current page. Howdo I grab that info from the first page? Here's the code:
Imports System Imports System.Web.UI Imports System.Web.UI.WebControls Partial Class mstrIntranet Inherits System.Web.UI.MasterPage Public Property mSearchName() Get Return txtSearchName.tex End Get Set(ByVal value) txtSearchName.text = value End Set End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load txtSearchName.Text = "People Search" End Sub End Class
Search Results Code Behind page:
Partial Class PeopleSearch2 Inherits System.Web.UI.Page Public SearchName As String
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim mpTextbox As TextBox mpTextbox = CType(Master.FindControl("txtSearchName"), TextBox) SearchName = mpTextbox.Text
I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?
2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.
We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.
I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3 endif
When inserting, i would like to check if the record exists in the table, then if it doesn't, insert it, else either redirecting to a different page, or showing a message box saying "Record already exists" ...
