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?

Accessing Form Control From A Master Page

Sep 29, 2012

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

Javascript - How To Check Whether A Certain Text Box Exists In A Page

Feb 9, 2010

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.

How I can I do that in javascript?

Web Forms :: Check For Session In Master Page Before Child Page?

Sep 28, 2010

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.

Web Forms :: Content Page Retrieve Info From Master Page Form?

Dec 7, 2010

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:

Master page:

< FORM id=formEmpSearch method=post action=~/About/peopleSearch.aspx runat="server">
< asp:TextBox style="WIDTH: 153px; HEIGHT: 12px" id=txtSearchName onfocus="this.value=''" runat="server" CssClass="searchBox">

Master Code Behind page:

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

Web Forms :: FTP Download - How To Check File Exists

Dec 7, 2010

What is the way to :

1) Check if a file exists on an FTP site.

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.

Forms Data Controls :: Check If A GridView Exists?

Dec 9, 2010

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

but the code still executes.

Web Forms :: Check If Child Node Exists On Treeview?

Jan 24, 2011

I have some data that I am putting on a treeview and have a checkbox on the page to decide if the user wants to order the nodes by date or type.

To do this I need to check if the code has already added a child node so when grouping by the type I don't put it in lots of times.

Lets say I have Type 1 and Type 2 and each have 3 items that would fall under these I want to achieve:

Type 1
Item 1
Item 2
Item 3
Type 2
Item 1
Item 2
Item 3

Instead of:

Type 1
Item 1
Type 1
Item 2

etc etc etc

I tried using the node.Contains function but it doesn't seem to exist (I am using c#).
