I have a webusercontrol which has a form. When I place the control on a page, and the form on the webusercontrol is submitted, I set a parameter on the control which I like to pass to the parent page. I am setting the parameter within the control using
private
int _Status;public
int status {
[code]...
My form calls a sub for the onclick of the submit button. I need to access the form element with id 'form1' from this sub. I know in javascript its document.getElementById but how is this done in ASP.NET VB? And Yes I do realize I just showed off how much of a newb I am to the language but this seems to be so easy that its almost unsearchable on google.
View 6 RepliesI am building a web application that needs to be able to interact with a desktop application. Essentially, what I need to be able to do is to execute an .EXE file with command line arguments on the client from the web application when a form submits. My initial thought is to develop an ActiveX control to handle this, but I have never done this before.

I have made 3 web controls which need to be accessible between eachother. First control is main control (controlA). Other 2 controls (controlB and controlC) are referenced in controlA. Now i need to access function from controlC and call it in controlB. I tried adding new reference, but it doesnt work the way I want it.
ControlA is main control and it is merely a table to hold other 2 controls in place. I can access both controls from controlA, but since I need to modify controlC due to drop down menu in controlB i can't force controlA to respond to event in controlB every time it occurs and affect controlC. Or can i? :)
So whenever the event (SelectedIndexChanged) of drop down menu occurs in controlB, I need to set up/change controlC. Problem is, I don't know how to call function from controlC. It may sound very simple to solve and i tried to make a new instance of controlC class in controlB my webpage just wouldn't load.
This may be a really dumb question but when I try to access this field in the code behind file
<input ID="txtOldFile" type=file /> it says txtOldFile does not exist.
What I want to do is access a directory and select a file name which I will then use in code.

I was able to acces an HTML element from my c# code this way:
Page.Request.Form["Name"].ToString(), where name was an html element:
<input id="Name" style="z-index: 102;" type="file">
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?
accessing a table on a page's masterpage.
So I have a sitemaster page and I am getting header and footer controls from it. But for a perticular page I would like not to show the footer and just the header.
Therefore, I am trying to access the master page table control with id "footer".
What I have tried and they all didnt work. First I tried,
Dim ptrMaster As MasterPage = Page.Master
ptrMaster.FindControl("footer").Visible = False
This gives me a null pointer error.
Then I tried to put in a accessor method on the site.master (masterpage) itself.
Public Sub HideFooter()
Me.Controls("footer").Visible = False
End Sub
But the problem here is when I create a masterpage object on the page that I would like to not show the footer. I cant see the method. So if I do
Dim ptrMaster As MasterPage = Page.Master
ptrMaster.HideFooter()
HideFooter doesnt show up as a method.
