Web Forms :: Using Masterpage: Design View Is Not Working On The Content Form
Feb 14, 2011
I have the following problem:
I have started to use Masterpages, and normally you can code in the Source view and also you can switch to the Design view and watch everything you did, but, when I´ve introduced master-pages, I can see only the master page design view but I cannot see the Content form design!!! :S
I have a page that opens inside a MasterPage. Let's call it the ChidPage. Now when I put an ASP:Button on the child page, its event doesn't fire at all (postback isn't done). While LinkButton on the same ChildPage is working just fine. However if I do something like
It works just fine. But still there is No PostBack with this button, the same event when wired with a LinkButton works just fine. I have ASP.NET 2.0.
I don't know if this is a basic question or not as I'm brand new to master pages.
I am using VS2010 and an automatically generated asp.net (C#) website. It created the site.master for me which I then edited to give the look for my site.
For some reason I can't drag and drop controls from the toolbox onto each of my content pages. I know I can add them in code but they then don't get added to the designer.cs file and of course if I add them manually they'll get overwritten at the next build.
As I say, I don't know if this is normal behaviour or not but I need to know how to add controls to my automatically generated ContentPlaceHolder with it's associated aspx file with Content tags.
When I try to look at my masterpage/form in design view it's only partially visible. It's shifted so far to the left that i can only see the right half of it. I don't understand why. I'm using negative margins to center the form at runtime, which is working great. It appears to be shifted to left about half of it's width, which would equal the negative margin.
CSS for negative margin:
Is this a deficiency with the rendering in Design view? Is it a discrepancy between the way a browser would interpret the styles and the was the Design view interprets them?
I have a masterpage with a content area. When viewing a page in the designer the content area is so narrow it blows the page formatting to pieces. When viewed in a browser it looks fine, just looks bad in the designer.
I've seen other projects on other computers that don't have this problem ... is there a setting for this?
After opening an existing proyect in visual studio 2010, the web form in design view doens't work. All server control puts a gray box with the following message : Error Creating Control - imgTransportistaSession state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.
I am trying to use Matt Dotson FrozenGrid View [http://blogs.msdn.com/b/mattdotson/archive/2006/03/02/542613.aspx] in Master/Content page but the header of the gridview doesn't get fixed. I tried putting gridview inside the panel and but no luck.
can't connect to sql 2005 express sp1 and vs is also sp1. 2) Which my guess is because of the database connection not being able... design view is not able to pull in the application for design, it's as if there is no theme and css just white background and black print.
We would like to use a contentPlaceHolder in our pages to set titles. What we would like to do is have the masterpage check the contentPlaceHolder to see if it has content in it. This way we can set up an e-mailer that will tell us what pages that don't have page titles since we have a fairly large site. We also have nested masterpages.
I've got a number of MasterPages with ContentPlaceHolders. I do not know how much Placeholders are on the MasterPage. Now i want to load Content to the PlaceHolder, id the ContentPlaceHolder exists. When i use the this.Master.FindControl the MasterPage renders and the added Content would not be rendered. See: [URL] Soo I tried two posibilities of adding the content:
The first way seems to be the faster way. But which is the "better" way? Would any of this make any problems?
its not working from client side alone after I disable the code behind attributes.add but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?
Greetings. I have a master page called 'site.master'. I have a web form called MyForm.aspx that uses site.master. I have a Label control on site.master called "lblMessage". I have an UpdatePanel that contains a Button control called "btnSave". When the Save button is clicked, it updates the database via the data access layer and then should display whether or not the save was successful. I want to set the lblMessage.Text property (on master page) to display this information. I am currently implementing a method that finds the control in the master page and sets its property and this works successfully (verified via debugging), but the problem is that, because the button is in an UpdatePanel, it is not displaying the text for the lblMessage Label on the master page. In short, any ideas on how I can set the Text property of a Label control in a master page via an AJAX call from a button inside an update panel on a content page?
I have done master page and some content page..I have put three LABEL(not in inside the Content place holder) in masterpage and l have store some value..in this, the same value i want to use in content page..how to get that masterpage content value.
I am having a slight issue with grabbing data from my masterpage into my content page (as a whole).
I have generated a public property for the my textbox and the contentpage can see this public property. But it comes across empty (even from within the masterpage). Now I guess the problem is with the property itself (possibly). It also shows as empty when I response.write it's value to the page.
Even when I call the value of the property in the masterpage it comes across as empty. The way I have this setup is that a textbox named pageTitleField has it's value updated from an iframe. All is working well and the textbox has its value updated correct upon iframe content changes. This is great. Now I just need to pass this textbox value into my content page and then set it as the document title.
see my code thus far.
My MasterPage CodeFile
My ContentPage CodeFile
I know the public property is being seen from the content page because if I just do a Response.Write(Master.GrabPageTitle) I see System.Web.UI.WebControls.TextBox appearing as the output of that property. So it appears hat the textbox value is not being captured in the public readonly property.
I have a MasterPage in my project which it contains a FormView and the FormView is databound with a Connection String to a SQL DataBase.
This FormView is selecting users information from Database, when the ContentPage is loading, Im trying to get the information from the FormView of MasterPage and load them in Content Page, but it is not working fine for me.
In MasterPage I have a FormView such as follow:
In ContentPage, I have a Label and I want to get the name from MasterPage and replace it with the text of the Label.
I am doing this at PageLoad of Content Page with the Following Code:
At the page load of ContentPage, it says that it could not find the FormView1
but after I refresh the page, it works fine.
is there anyway for me to ask the FormView in MasterPage to DataBind and After that, it retrieves the Data from FormView and place them into the ContentPage.
I also tried: fv.databind() but it is not working.
How can I call a function in the masterpage from its content page I have a function in my master page to populate a tree view in the master page. After entering some database values from the contentpage I want to call the master page function to show the entered value in the treeview.
I am tryign to make the master page code globally do some chaecking before the content page loads. Pageload event in Masterpage is executed after the content page for some strange reason. How do I go about this?
I have a label on the master page that is updated by the contents pages. Rather then create a content placeholder that will contain only this label, I was hoping to be able to modify it directly. I have the label called lblYAO on the masterpage, and in the code behind I have
Public Sub DisplayDataFromPage(ByVal message As String) lblYAO.Text = message End Sub
I know I can modify the page directive on the content pages, but there is another person who will be adding pages, and this may be a bit much for him. In the content page's code behind, I would like to do something like Page.Master = "something" but I understand I have to explicitly cast it to the appropriate type first? This is as far as the examples I've seen have gotten me. I haven't seen any casting examples.
