.net - Referencing Code-behind Properties On .aspx Page?
May 15, 2011
On a .aspx page, what is the best way to link a server control's property to a property of the page class (its code-behind)? The only way that I have read about is to use databinding:
and then call Me.txt.DataBind() or Me.Databind() from the codebehind. Is there any way of establishing this relationship on the .aspx page alone, or simplifying the process if you have many controls to bind (without binding the entire page)?
I need to post some xml data to a different aspx page and redirect to the same page.I tried the following code it does post to the page sucessfully but i need to redirect to the same page with posted data
I've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?
How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.
Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.
I have created a class containing a few string extensions, as follows:
Imports Microsoft.VisualBasic Namespace Extensions <HideModuleName()> _ Public Module Extensions
[code]....
just in case it's relevant to this, I'm using .Net Framework 2.0.Would I need to register something within the aspx page in order to use extensions? If not, is there another way to enable them?
I have 2 pages. parent.aspx and child.aspx. In parent.aspx, i use colorbox and send some value for the child.aspx to popup.
[code]...
child.aspx will popup and shows ASPxGridView base on the value passing from parent.aspx. User will select the data from ASPxGridView. the selected data need to send back to the parent page. I code it in child.aspx.vb page.My problem is how can i get the value from child.aspx.vb and pass it to parent.aspx ?
i have my first aspx page that has data thatthe user fills in. it is in format of textbox's and at the end of it all the user clicks submit and all data goes in the database. In the database each record gets an ID field. Now when the users clicks submit and goes to the next page, i want the ID's (they could be 1 to 1000+) from the DB that he just inserted and have them available on the second page. how can i take all the id's from page 1 to page 2? can i do it in session?
I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.
Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.
I have an asp image within my "default.aspx" page.I set cookies on my masterpage vb file and depending on the cookie set, I want to show or hide this image.
I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) 'set selected user from gridview.
[Code].....
This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?
I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox. The checkboxes are created dynamically, so I only know the prefix for finding it. So, I need to find these checkboxes by iterating the controls on the page somehow. It's not working out.
I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.
Is is possible to retrieve the ID value from the Request.QueryString from a aspx file and pass it onto a ascx file in order to successfully update a profile using the retrieved ID?
In my web app, I have an aspx page which contains an html table and several lines of text. I need users to be able to download this whole page as a separate file.
In the past I have used the a webclient to do this:
Dim myWebClient As New System.Net.WebClient myWebClient.DownloadFile(strSource, strDest) Response.AddHeader("Content-Disposition", "attachment;filename=test.doc") Response.Write("test.doc")
but it appears this is only able to download html pages.
I have 3 vb classes and I am trying to add them to my aspx vb page. I try to do
Dim Class1 as new class1 but only one of them works, the other 2 do not work. I made a sample class and put the following in it:
Public Class test Public Sub test (byref test as string) test = 5 end sub End Class
Then I went and tried to do Dim test as new test but it doesn't work, what am I doing wrong? The other class works fine and I don't know why this one wouldn't.
I need help in designing an aspx / vb page (.NET 1.1):The result is a table with 3 rows A,B and C it should look like this:
A B C
A, B and C have fixed height of 5 lines / 20 lines / 5 lines B content are gathered from dataset and can be more than 20 lines and then it should be splat and hole new table is created under the the first one like this:
I have a login page that return the userName to a page called User.aspx.The User.aspx shows the information about the user based on a sql select. I fill 12 labels on the page with the result of the select.I want to keep the information of my 12 labels if the user Quits and enter again in the page.I save my session
Session("UserPage") = (litHello.Text And litAddresse.Text And litAnimalGenre.Text And litCouriel.Text And litNomAnimal.Text And litPays.Text And litPostalCode.Text And litProvince.Text And litRace.Text And litTel.Text And litVille.Text)
Now how I can proceed too fill all my label with my saved session call UserPage??
In my asp.net project, I have two particular aspx pages (lets say PageA.aspx and PageB.aspx)
In the codebehind PageA.aspx.vb, I want to call "Sub GetDefaultValues()" which happens to be in PageB.aspx
Update:PageB.aspx has textbox controls that contain default values (which are being read in Sub GetDefaultValues). Those default values get populated into the textboxes of PageA.aspx (based on certain conditions)
I am printing reports as tables in .aspx pageNow i want to print that section containing table. how can i print that section only?As I got javascript function to print the whole page with window.print() but I want only some section to get printed.
In the process of converting a page from normal postbacks to AJAX-calls (using JavaScript to load/control the UI entirely and use ASP.Net strictly as a backend), I found myself wanting to replace a GridView with a AJAX-sourced dataset.
I am trying to figure out how to preserve the values of the controls on this page (just the user-submitted commission value and the sales region (eastern is 10% and western is 20%)).[code]...
tts.exe produces an mp3 file which contains synthesized speech based on the given text.lsrunas.exe is the known utility to run the exe as another user.
Shell( command_line, True ) If i run the 'command_line' from the Start->Run menu (its win xp pro), then the EXE works ok. But when it runs through the aspx page and Shell, it produces an error and terminates. Sorry i cant recall the error code (something like 0x400...) but in a little search i did it has something to do with DLL initialization, the app cant start correctly.
As i said, the 'command_line' (as given from me above) works ok using the start->run dialog. i am pretty sure it has something to do with Rights. This service made from me a year ago, it worked then after lot of headaches, but now after a new windows installation i cant remember what i did to make it work.
