Web Forms :: Content Page Modifying A Label On The Masterpage?
Feb 16, 2011
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.

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.

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.
For Example:
In MasterPage I have a FormView such as follow:
Name: Amir
LastName:Zandi
Username:amirzandi
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:
[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.

Using VS 2010 RC, VB, I have a label on a masterpage that is hidden. I want to make it visible from a content page when needed, and have the text change on the label as well from the master page.
I am using the following to access the label, but the text and other properties don't change for some reason.
Dim lblErrorMessage As Label lblErrorMessage = CType(Master.FindControl("lblErrorMessage1"), Label)
lblErrorMessage.Style.Add("display", "inline")
lblErrorMessage.Text = "LoginID ALREADY EXISTS!!! Please choose a different ID"

I have created a great stand-alone web form in asp.net utilizing many jQuery features and CSS. It works fine. When I re-create it as a web content form as part of a MasterPage, my jQuery and javascript is completely ignored.
I am referencing the pertinent jQuery and CSS in my of the MasterPage. I have a content placeholder at the bottom of the masterpage called "ScriptContent". In my content page, this is where I plug in the various jQuery methods and javascript.
When I view the page source everything is there. However, it's all being ignored so to speak. What am I doing wrong?

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:

Second way:

The first way seems to be the faster way. But which is the "better" way? Would any of this make any problems?

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 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
[Code]....
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.
