Asp.net - Enable/disable Web Elements Of A Parent Aspx Page From The Child Ascx Page?
Jul 20, 2009
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 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 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?
Using vb.net on an aspx code behind event, is there away to tell from a parent page if the child page popup is open, and then close the child page if it is truly open based on some event on the parent page, like clicking a gridview edit link, again?
I have an ASP.NET page (WebForm) on which I set the content of a central DIV by dynamically loading one of five user controls during Page_Load, dependant on the stage of the application.
One of the user controls contains radio buttons and a text box together with a submit button. What I want to do is process that information when the form is posted using the submit button.
I could do this with an AJAX call using jQuery, but I don't really want to do that, so I'm trying to access the form data on postback, but on page load following the postback the data is not present in the Request.Form object.
Looking at what I need to do it seems pretty simple and I'm sure is once you've got your head around it, but I can't find out how to carry this out. Some of the things I have read refer to event bubbling, but that doesn't make too much sense in this scenario.
EDIT: To clarify, I want to post the page back to itself to capture the values from the form elements via the Request object, store them in the database, and then display a confirmation message (or something else) on postback, and not re-display the same control again. So I won't be loading the same user control again.
I'm writing an MDI app in vb.net vs2010. The MDI form has the default MDIMenustrip menu with several menu items. Each has some subitems. None of the child forms have a menustrip defined. I thought it would be easy to call a public subroutine in the MDI that would disable or enable the MDIMenustrip items. If I execute the routine from the MDI form, the menu items disable/enable just fine. THe problem I have is when I call the routine from a child form. How can I control the MDI menu from a child form?
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 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 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 an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.
