Web Forms :: PreviousPage.Master.FindControl("ContentPlaceHolder1") Is Null?

Jan 19, 2010

I have a masterpage with three ContentPlaceHolder and a page derive from it.

Let's call the page derive from it as "PageFrom", the "PageFrom" has a GridView.

Each row in the GridView has a linkbutton which do a cross page postback to another page, "PageTo"

And I am trying to grab any control in the "PageFrom"

I have tried PreviousPage.FindControl() and PreviousPage.Master.FindControl(), none of them works.

The master page code


The PageFrom


The "PageTo" code-behind

C# - DetailsView FindControl() Returns Null After Some Postbacks?

Jan 7, 2010

I've been working for a long time with GridViews and DetailsViews, but yesterday I've come across a new scenario, which I quite do not understand.

I have a GridView with ImageButton (CommandName="Insert") which will change the mode of the DetailsView to Insert. Afterwards I'll look for a DropDownList inside that DetailsView and add some items dynamically. Works fine, but one first the first time I press that ImageButton. If I click on "Cancel" in the DetailsView and press the ImageButton again, the .FindControl() Method returns null.

I've created this sample: (To make it run in your Visual Studio, just bind a DataSource to the DetailsView, otherwise it will not be rendered)


<asp:GridView ID="gvCategory" runat="server" OnRowCommand="gvCategory_RowCommand">


I have also tried using a ItemTemplate, and not a InsertItemTemplate, but this results in the same. After using the ChangeMode-Method the DetailsView.CurrentMode == InsertMode. The only thing I can think of is, that the markup is already generated for the ItemTemplate and changing the Mode to InsertMode can't affect the rendered markup, or something like this.

Using C# FindControl To Find User Control In The Master Page

Mar 31, 2010

So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.




protected void goToSelectedPage(object sender, System.EventArgs e)
temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1;
ct.ID = "TestMe";
//This is where I CANNOT SEEM TO FIND THE CONTROL ////////////////////////////////////////
protected void lnkSave_Click(object sender, System.EventArgs e)
UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel;
Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control;
temp1 test3 = test2.FindControl("TestMe") as temp1;
string maybe = test3.Col1TopTitle;

Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs

protected void Page_Load(object sender, EventArgs e)
string ppp = this.ID;
string par = this.Parent.ID;

Web Forms :: Master Page Controls Cause Null Reference Exceptions?

Mar 10, 2010

I've got a master page where I've created two content place holders ('menu content place holder' and 'main body content place holder'). I've placed several controls (drop down lists and a calendar) in one of these content place holders (the 'menu content place holder'). In my content page I've set the 'menu content place holder' to 'Default to Master page content'. In my 'main body content place holder' I've included several controls (table, labels) which depend on the user selected items in the 'menu content place holder'.

After including a reference in all the necessary places- like this:

DropDownList ddlList1 = Master.FindControl("ddlList1")

I still get the following exception (this exception occurs in my content page):

An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:System.NullReferenceException: Object reference not set to an instance of an object.

Web Forms :: Get The Value Of A Textbox Using PreviousPage Method Along With A MasterPage?

Aug 20, 2010

I'm trying to get the value of a textbox using the PreviousPage method and the previous page utilizes a MasterPage for the page's layout. I've read through many forums laying out the ground work on how to do this, but for whatever reason I am just being unsucessfull in getting this to work in my project.

Mark-up of previous page using a master page template:


VB Code-behind page for second page:


What really confuses me is that when I step through the code it goes all the way through the if statement but never gets the text value from the previous page.

C# - ViewData Set In An ActionFilter Is Coming Out Null On Master Page MVC3?

My Original Issue here:Help! I've got repository access in my MVC master page! Refactor time!What originated as a re factoring job to improve performance has revealed new issues. If I should keep this in my original question - feel free to delete this one, and rename the old one to something more relevant. I'm using an ActionFilter applied to a base controller to load some user-customized settings. My issue is that I save these settings in the filterContext.Controller.ViewData object but its coming through as null on my master page. Here is the relevant code:

Retaining PreviousPage Information After Postback?

Jul 29, 2010

I'm using the asp.net PreviousPage functionality and cross-page postback. The problem i'm running into is that if I have any postbacks on my page, the PreviousPage information seems to be lost. I don't want to put it in ViewState because that will be quite large. I've thought about Session, but I don't want the data to persist after i've moved on to another page, and I really don't like the idea of putting code in all my other pages to delete old session variables.

Easiest Method To Build Where Clause From Checked Items In DataList Of PreviousPage

Jun 25, 2010

I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table. The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.

So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items). Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable. Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?

State Management :: Access PreviousPage On Button Click Handler Of Target Page

Oct 12, 2010

I Have two pages source.aspx and target.aspx. Source.aspx has one button and other form controls the collect input. The button has its postbackurl property set to target.aspx. On target.aspx I have another button and other form controls that collect input. When the user clicks on the target.aspx button, I want the inputs from both source and target gathered to be inserted into the database. The problem is the Page.PreviousPage property is only available during the initial rendering of the target.aspx page. So when I click on target.aspx button, PreviousPage is now null.

One strategy of mine is to collect the information on page_load and store it in ViewState, but is there any other method that I should consider in this process. I think the cleanest approach would be to somehow access PreviousPage on the button_click event handler, but how can I access this property.
