I have been asked to support a legacy app and I can't get access to the code behind files. I need to add a new feature that gets a list of items from the database on page_load, what way would adding an "in-page" page_load affect the compiled page_load?

I have an usercontrol with fck editor for allowing user to add note in my aspx page, which allows the user all kind of text formatting.My need is that I have to access user control from the code behind and collect the content as the same format some one has entered in the fck editor.How can I do this?
View 2 RepliesI am an experienced web developer but sometimes ASP.Net is tricking me. I have a master page in asp.net. Then I have a page based on that master page (home.aspx). Now in home.aspx.cs I want to access the asp:content controls to add controls programmatically.
Aspx looks like this:
<asp:Content ID="leftCol" ContentPlaceHolderID="cphLeftCol" Runat="Server">
<asp:PlaceHolder ID="phLeftCol" runat="server">
</asp:PlaceHolder>
</asp:Content>
I would expect that I can reference "leftCol" from my code behind. But it's unknown there. For testing I added my own placeholder "phLeftCol". I can reference that without issues.
I am dynamically creating div tags in my code behind and adding code into the innerHTML property of the div tag and then rendering out the html to replace values inside of a table structure that I have, I then place all the table code onto the page. I want to be able to access the div tags again from the code behind, but can't seem to because well obviously they aren't set to runat="server". Is there any way to do this or to set them so they can runat server.
View 4 RepliesI cannot access my UI controls on my ASP.Net website.
When I create a brand new form and drag a control on it, I can use C# to change the properties of the control easily, like one would expect.
But when I try to do the same on another page, I cannot access any control whether I drag a new control on the page or not.
It seems the code behind and the visual page aren't connected.
my application runs on the client side. I have to access a display on the asp page via javascript. I have the following code working properly:
ClientSript.RegisterStartupScript(this.GetType(), "allMessages", "<script>document.forms[0].tbDisplay.value='Messages'; </script>");
tbDisplay is a "text box" asp:textbox control. I need to replace de 'Messages' for avariable. so instead of printing "Messages" all the time, I can change the information on the variable prior to display the message. how to change 'Messages' to a variable.
Is there a way i can access a certain textbox in the .asps.cs file code?
I have an insert statement where i have a textbox like so for example:
PHP Code:
<asp:TextBox ID="txt_title" runat="server"</asp:TextBox>
And then in the backend i access it like to txt_title.Text;
This is fine. However i have a calendar popup which is shown:
PHP Code:
[code]....
A calendar popup appears when i click on the button. Now i need to insert the textbox value in the database but i cant seem to get access to it in the .cs file. I have tried adding runat="server" but it then stops the popup from working.
I was wondering if I could add a user control to a page with a parameter and then access that parameter in the code behiind for initiallization.
For example on my aspx page i would have somethign like.

I'm having trouble accessing custom profile properties that I've declared in my web.config using the TableProfileProvider available at [URL] I set everything up according to the instructions but keep receiving an error stating "The type or namespace name 'Profile' could not be found" whenever I refer to the Profile object in my codebehind. My web.config is:

I have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End Sub
I've started to figure this out based on other questions I looked up on here, but all of them were in C# instead of VB, so this is as far as I got:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
End If
End Sub
So yeah I'm not sure exactly how to finish it. here's my code now:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
CheckBox checkGenEd = formview1.FindControl("checkGenEd");
Panel panelOutcome = formview1.FindControl("panelOutcome");
End If
End Sub
It's also saying that checkGenEd and panelOutcome are not declared. I changed my code to this but it still doesn't work:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
Dim checkGenEd As CheckBox = FormView1.FindControl("checkGenEd")
Dim panelOutcome As Panel = FormView1.FindControl("panelOutcome")
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End If
End Sub
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.
i want to access loginname of login view control for some other reason also i tried something like this but not working
My design time code is

and at code behind i tried this normally by string nm= LoginName1.Text ; LoginView1.Findcontrols("LoginName1"), using the LoginView1.Controls[0]. controls collection... (this get only controls from the anonymoustemplate)LoginView1_ViewChanged also doesent work because since the change in 2005 (or sth) logging in doesn't trigger this event (didn't try it, just read that it doesn't :)) but not able to access the value of loginname1.
