VS 2010 / Accessing Controls On A Page?

Nov 22, 2011

This is my html:

Code:
<!-- ADD PRINTER -->
<asp:Panel ID="AddPanel" runat="server" Visible="false" CssClass="aspPanel">
<h1>Add Printer</h1>
<p><asp:Label ID="lblPrinterEmailAddress" OnLoad="ProcesstextValues" runat="server" Text="Common/Label/EmailAddr" CssClass="aspLabel" />

[Code]......

When the user hits the Save button, AddSaveChanges_Click() is called. In that procedure, I want to make sure the user has entered a valid email in txbPrinterEmailAddress. The problem is when I reference RegExEmailValidator in my code behind, I get object reference not set to an instance. This is my code when I detect the invalid email

Code:

Else
Logwriter.LoggerWrite(String.Format("Page is NOT valid and {0} is an invalid email id", txbPrinterEmailAddress.Text), "MyLog")
'EditPanel.Visible = True
'ShowListPanel.Visible = False
'AddPanel.Visible = False
RegExEmailValidator.Enabled = True
RegExEmailValidator.Validate()
End If

And my log entries are:

11/22/2011 1:40:37 PM Page is NOT valid and xxxxxx is an invalid email id

11/22/2011 1:40:37 PM EXCEPTION in AddSaveChanges_Click() - Object reference not set to an instance of an object.Why is RegExEmailValidator not an instantiated object?

VS 2010 - Content Page Accessing Event Handlers From Two Different Master Pages

Jul 1, 2013

I have a ASP.NET content page where the master page is set dynamically. Both master pages contain a print button and an associated event handler for the click event of the button. Unfortunately I receive a run-time error when I attempt to dynamically access the event from the master page that was not initially assigned. Below are code snippets:

Page_Load():
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim strPageTitle As String = "Evaluator Data Form - Instructions"
If Page.MasterPageFile.Contains("masEvaluators.master") Then
Dim mp As Evaluators_masEvaluators = CType(Me.Master, Evaluators_masEvaluators)

[code]....

which produces the following error when I load the page and reference the "masStaff.master" master page:

System.InvalidCastException: Unable to cast object of type 'ASP.staff_masstaff_master' to type 'Evaluators_masEvaluators'. at Evaluators_EDF_Instructions.Page_Load....

I can solve the problem by adding a print button to the content page, but that defeats the purpose of using a master page.

VS 2010 - Accessing Dynamically Created Server Controls

Jun 8, 2012

Ok, so I'm dynamically adding <input type="File" />'s to the page via button click, client-side via Javascript.

Now when I click the upload button I can access the PostedFiles server side, but I also have radio button lists that I've created dynamically as well with no runat="server".

If I were to .setAttribute("runat","server") for the radio lists I create, is there a way to access that client-side created server control, from the server side?

Forms Data Controls :: Accessing Master Page Controls From Content Page Formview?

Sep 22, 2010

I have a master page with a textbox that I want to use for a search, and display the results on the content page.

I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.

The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.

How do I set this master page search box as the parameter for my datasource?

Accessing Controls / Events On A Master Page From Child Page

Sep 3, 2010

I have a problem i am trying to work out the best method with my limited skills. Im using vb.net(VS 2010) I am using a dll for an IFrame , which is call from code behind. On my site I havea masterpage which has two gridviews. ( GrdViewWebBureau is the one i am using for this query) GrdViewWebBureau is contained within an update panel and updated on a timer control trigger. GrdViewWebBureau updates the page with file counts and status from our clients. I can click on any one of the cells and the code behind is fired. What I am trying to do is put an IFrame on the master page and every time a user clicks on the grid, the Iframe is fired up.

I have tested the iframe and vb code behind from a dummy page and it works, however when the Iframe is on the master page it doeant work. What I am tryingh to achieve is that no matter what page a user is on the site, they will be able to click on the GrdViewWebBureau and the iframe will fire with the correct childpage. Each webPage may also have an Iframe as well, so i dont know if it is possible to make the IFrame global and just call that control ?? I have no idea if 1 this is possible with the code i have and 2, if i have the brains to understand the who what why and when.

VS 2010 - Accessing Data From Dynamically Created DropdownLists

Dec 20, 2012

I have it setup so that when a user selects an item from a DropdownList, that some DropdownLists are dynamically created, based on the results from the Database that are returned after selecting the item in the first DropDownList.

Then, I have a button that takes the data and saves it to an object I've created for this, and I try to iterate through the Controls of the Placeholder that I added the DropdownList controls to.

However, the Placeholder says there are no controls in it, when I press the button, but I can obviously see them there.

Here is some code:

When a "Pilot" is selected, I get all of the Upgrade Types that that "Pilot" has access to, then I create a DropdownList for each type of Upgrade with all the actual Upgrades of that Type:

VB Code:
For Each u As UpgradeTypeList In upgrades           
Dim lbl As New Label           
Dim ddl As New DropDownList            
ddl.AutoPostBack = False            

[Code] ....

Then, when the "Add Squad Member" button is pressed, I am trying to iterate through the controls, pick out any DropdownLists and get the values from them and add them to a List Of in an object for the Pilot info:

VB Code:
Protected Sub btnAddSquadMember_Click(sender As Object, e As EventArgs) Handles btnAddSquadMember.Click   
For Each c As Control In rowUpgrades.Controls           
If TypeOf c Is DropDownList Then               
Dim DoesExist As Boolean = False                

[Code] ....

But, the controls supposedly don't exist and no values get added to the List(Of).

Accessing Controls In An Aspx Page?

Jun 28, 2010

We have some code which is designed to build up a key/value pair of controls on a ASP.NET webforms page and their values. We use the "Controls" collection and recursion to build up this key/value pair.

The only issue is that ascx controls don't appear to come back in the "Controls" collection. Instead we get the controls on the ascx.

Something similar to the following code:

[Code]....

The subCtl is never a ascx control. Is there a way to get a list of the ascx controls on page or better still a different collection that contains both types?

C# - Accessing Page Controls From A Separate Class?

Aug 6, 2010

I'm wondering how I can go about accessing page controls from a separate class I've made. I've tried a few things I found using google, but no luck :(

What I'm trying to do is keep a function that is used often, in a global class.

The function then accesses a page literal and calls ScriptManager.RegisterStartupScript. I was hoping this is possible, so then this function wouldn't have to be copied to all of the pages.

Accessing Dynamic Controls On Next Page When Redirecting With PostBackURL?

I had a issue with accessing dynamic controls in destination.aspx, which i had created during runtime while populating them in a panel in source.aspx.

In source.aspx, i generate controls and fill them up in a panel, after that, this page was posted to destination.aspx. however, i am unable to retrieve my controls at the destination page.

Following are some of the ways i had tried.

this does not work at all, i can't cast a control using a request, it only returns me a string.

C# - Event Handler In Masterpage Accessing Controls In The Client Page?

Jan 4, 2011

I have a button on a masterpage, which when clicked, calls a method that takes an EventHandler previously saved to the viewstate, this method is on the client page, and executes it:

protected void Save_Click(object sender, EventArgs e)
{
this.SaveButtonEvent += (EventHandler)ViewState["saveEvent"];
if (this.SaveButtonEvent != null)
{
this.SaveButtonEvent(sender, e);
}
}

This then calls a very simple method on the client page:

protected void Button2_Click(object sender, EventArgs e)
{
Label1.Text = TextBox2.Text;
}

However, the value of TextBox2 is incorrect, it is the value of the text box that was set when the page loaded (or if any other item on the pages changes it), the new value is not passed.

If I add a button to the client page, that calls the Button2_Click event directly, it get's the correct value.

Is the reason I am not getting the correct value of the text box because the Event is called from the master page?

I should add, that this button is created dynamically, and the event delegate will vary, which is why I have to set it at run time. I need a way to set the delegate on a click, and persist this until it is changed again.

Forms Data Controls :: Accessing A Label In A Page From A Gridview?

Mar 5, 2011

In a page, there is a lable called lblTotal and a gridview with 3 columns; Name, Percentage and Amount.

Name and Percent are values that come from a database. Next I need the caluclate the Amount field. The Amount field should be set by taking the Percentage column value in each row, against the value in lblTotal and displayed in the Amount column

So for example

If the value in lblTotal is £200 and the dataset in my gridview looks like this...

Name......Percent......Amount
John......20%..........
Dave......60%..........
Mark......20%..........

Then the result would be this

Name......Percent......Amount
John......20%..........£40
Dave......60%..........£120
Mark......20%..........£40

So I guess I would need to do this using OnRowCreated and do a find control maybe?

Web Forms :: Accessing Controls After Redirecting To Same Page On Button Click?

Jan 3, 2011

on my default.aspx page, i have one dropdownlist (which has book types as values e.g. small books, medium books etc.). Then one textbox. And one button named 'Search'. On button click the datagrid shows result by filtering table data with book type and search string that user enter in textbox.

So on 'Search' button click, i want to load the same page with result but with query string like 'Default.aspx?booktype=small' (using response.redirect) if user selects small in dropdown list. The problem is when i click 'Search' button and the page gets loaded again I cannot access dropdownlist values and search string that user has entered. It takes null only when I use,
