Web Forms :: Accessing Previous Content Page Control?
Jan 4, 2011
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?
To be specific, I get the below error:
Microsoft JScript runtime error: Objected expected/required at this line document.getElementById('<%=txtemailId.ClientID %>').value
txtemailId is in the content page.
The reason I guess is that when .net is parsing the files, it is unable to substitute txtemailId.ClientID with the client side value that would be generated later on. So, how should one go about it?
i am having three pages.first of all i fill register page it will redirected to next page .again i will fill this pageto move to next page. in this time i want to go back to previous page and want to edit content of that prevoius page.in this time i got one problem like"Violation of PRIMARY KEY constraint 'PK_Skills'.

Need accessing the rendered content of a PLACEHOLDER control. I dynamically add a web forms page to a placeholder using "TABLE" this works great (cell row table placeholder ) now I wish to take that placeholder and use the rendered page to generate a PDF document.
If it possible to access the rendered code how would this be done?
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?
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'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
How can I build a query in a new page using the value from a prevous pages control's value. I can transfer the value to the new page, I just don't know how to use the passed value to build a query. I want to populate a data grid filtering with values obtained from the proveous page.
i have a masterpage and has some linkbuttons in it, i also have a webform which is a content page for the masterpage. i like to access the controls to the webform via the linkbutton residing in the masterpage or access the linkbuttons via the webform controls.
I have a master page with a textbox that I want to use for a search, and display the results on the content page.
I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.
The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.
How do I set this master page search box as the parameter for my datasource?
I have a ASP.NET content page where the master page is set dynamically. Both master pages contain a print button and an associated event handler for the click event of the button. Unfortunately I receive a run-time error when I attempt to dynamically access the event from the master page that was not initially assigned. Below are code snippets:
Page_Load(): Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim strPageTitle As String = "Evaluator Data Form - Instructions" If Page.MasterPageFile.Contains("masEvaluators.master") Then Dim mp As Evaluators_masEvaluators = CType(Me.Master, Evaluators_masEvaluators)
which produces the following error when I load the page and reference the "masStaff.master" master page:
System.InvalidCastException: Unable to cast object of type 'ASP.staff_masstaff_master' to type 'Evaluators_masEvaluators'. at Evaluators_EDF_Instructions.Page_Load....
I can solve the problem by adding a print button to the content page, but that defeats the purpose of using a master page.
I am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
The code was working correctly until i used a master page.
R.aspx vb Code: Dim athUsr As New AuthenticateUser() athUsr.IsLogIn("~/Login.aspx") If (IsPostBack = False) Then Dim objcoll As UserRegistrationColl objcoll = UserRegistrationProvider.GetDynamic(Nothing, "UserId='" + SessionManager.UserId.ToString + "'", Nothing) [code]...
I have looked everywhere for how to do this and all I come up with is threads describing how to expose public properties. I have a USER CONTROL in my Master page. It is a search box with a text box and a dropdown for search type (last name, account number, etc) and a search button. When the user clicks the search button, I open a new page that displays the results. How do I pass the values from the USER CONTROL search fields to the new page? I would post code, but I have nothing to post yet since I don't know where to start. I have tried exposing the public property of the user control, but I don't know how to retrieve those values on the results page.
I need to produce a report that will calculate values based on previous record field value and current record field value Can I store a field value say in a variable and then on the next detail line record have it accessed so I can say subtract current field value - previous field value from previous detail line?
