Web Forms :: How To Execute The Pageload In MasterPage Before The Content Page
Feb 2, 2011
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 masterPage on that i am using AjaxModalPopup for login purpose.My requirement is when i login via Master page then it should show the Logged-in User details on the current Content Page that is using same master page.
Here i am using following code to get it back to the same content page after succesful login but it does not show the user details on the same content page rather when i go to next page then it appears.
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 access querystring values in each content page's pageload method to get Username and Id. Is there a way I access the querysting values from Masterpage's pageload method and each content page goes to Masterpage to get those values without creating any other local variables in content pages? I know this can be done with Session's or view state but I was thinking to reduce redundancy of accessing query string in each content page.
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 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 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"
I'm new to asp world, and I have to keep my new job :)Switching form php to asp.net 3.5 (never used before). What would be the best practice for storing a SESSION variable in my project ?How can I prevent my SESSION to be overwritten if my initialisation code is in the onPageLoad method of my MasterPage ?My variables keeps beeing overwritten, please someone help me and tell me if there is any other solution than dealing with this pageLoad problem.
I have actually resolved my problem but I want to understand why. The scenario I have is an input for logging in on my Default.aspx page. When the user logs in the page refreshes and the login box changes to display a logout box using:
loginBox.visible = false
logoutBox.visible = true
My question is about the positioning of this code. I had my code validate the users input when the btnLogin is clicked. I then had those two lines above under PageLoad but this did not work. The user would log in but would have to refresh the page to update the boxes. Instead I had to place those two lines of code in the btnLogin Clicked area, at the same time as the user is validated.
It was always my understanding that when something on the page is clicked/activated the entire page is reloaded, but this appears not to be the case otherwise the PageLoad area should have worked.
When I view the page source everything is there. However, it's all being ignored so to speak. What am I doing wrong?
On my master page , I have "Search textbox" and "Search Button".On My content page , I have a "User Control" which has a "GridView".It shows some data about Vendors.Also, on this User Control's Page Load, i have code written to display all vendors in GridView.Now, when user enters Vendor Number in "Search textbox" , and hits "Search Button" , i want to handle this event inside my User Control.How to do this ?
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?
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
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.
