Web Forms :: Accessing To The Values Of MasterPage From Content Page?
Jan 12, 2010
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.
I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain content if a session variable is not null.
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.
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.
Is it possible to remove an item from the master page when within a content page? so in my example i have a column on left and right which i have created in the master using divs but i want to remove them in a particular page
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"
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
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.
Inside Page2.aspx file I'm trying to access Textbox1 control which is defined in Page1.aspx file but it gives error because it cannot find the control. The statement PreviousPage.FindControl("TextBox1") works only if Page1.aspx file is not tied to a master page. How can I find the control when both Page1.aspx and Page2.aspx files are part of the master page as shown below?
When I view the page source everything is there. However, it's all being ignored so to speak. What am I doing wrong?
