C# - JavaScript: Referencing A Control From Another Form?
Jan 29, 2011
My displaycloud.aspx page contains two databound data lists, each for displaying a tag cloud. The datalists have an EmptyDataTemplate that holds an empty label if nothing is retrieved from the db. I am trying to display the message 'Please Log a Story', by using the code below on the companyadmin page, but I am getting an error (the controls are not on the same page). How can I reference the labels positive_tags and negative_tags from displaycloud.aspx in companyadmin.aspx? Also, I want to redirect if the EmptyDataTemplate is not executed as shown at the very bottom of the page.displaycloud.aspx:
I am using a CustomValidator to compare two textbox control values in the form view. These values are not required but must be compared if a valuue is entered. The same two controls are defined in both Edit Item Template and Insert Item Template. The formview default mode is Edit.
The javascipt for the custom validator works when in Edit mode. However, when the form view is Insert, the javascript throws an error of NullReferenceException. how I can adjust my code so that the client-side javascript works for both Edit and Insert mode?
The form view is in a content page. The script is in the Head content placeholder
<script type="text/javascript"> <!-- function cvSecondaryEmail_Validate(source, args) {
I have a formview that runs of an SQLDS, very simple stuff. Inside that form i have various fields, one of them is a credit field, one of them is a debit field. Now i have put a radio button list with two radio buttons (credit and debit). What i want to do is when the "credit" radio button is enabled i want the "credit" text box to be enabled and visa versa.
I know how to reference an object inside a formview, but i am confused, do i reference the radio button list and then the list items inside it or?

We are currently developing an ASP.NET MVC application which will be deployed on a corporate intranet, with a slightly-modified customer facing version available on the public internet.We're making use of a number of external javascript libraries (e.g. jQuery) and a discussion has come up regarding referencing the libraries - should we reference them from an external source (e.g. via the Google load jQuery method) or keep our own version locally and reference from there?The project manager is a little concerned about having a 'dependency' on Google (or whoever) if we reference from there, and thinks that having our own copy of the library makes us more independent. On the other hand, I have heard there are a number of advantages to letting someone else host the library - for example, they handle versioning for us, Google aren't going anywhere anytime soon...
(for the purpose of the discussion assume the intranet we're hosting on has external access - obviously if it turns out it doesn't the decision is very much made for us!)So. Does this matter? And if so, what should we do and why?(I appreciate this is subjective - but it would be very useful to get advice from anyone with experience or thoughts on the matter. Not sure if this is a candidate for community wiki or not, let me know if I should have put it there and I'll know for future!)
I have Telerik RadGrid with a custom edit form. In my edit form there is a RadDatePicker to which I have added a custom footer template containing a 'Today' button. In the OnClick event of the button I call a Javascript function which takes the control ID to set the selected date. However, because the control is inside the edit form there is no variable created for it and the compiler throws an error when I try getting the client ID. The RadDatePicker is declared with:
The error I get is CS0103: The name 'ControlName' does not exist in the current context on the line referencing the ClientID. Is there another way in which to get the ID to pass to the Javascript function?
I have a label control on my MasterPage that is used to display error information. If an error occurs on another aspx page or a Module.vb page, how can I display the exception in the label control on my MasterPage? I tried using a Session variable, however, it would not work in my Module.vb code-behind file.
I thought this would be easy but i cant find what i am looking for online
I have 2 pages, the first 1 has a button that opens another page. On this 2nd page the user selects a picture. When the user selects a picture the form closes. When they select a picture i want the image control on the first page to change.
I'm not sure how to do this, i guess i could set the image path as a session variable and reload the first page but again i'm faced with the problem of how to reference the first page from the 2nd
I have created a class within the App_Code called shared_methods.vb where I use methods that are frequently used within several pages.
I have a hyperlink control within the masterpage that i want to change the NavigateUrl depedning on what page. Just for better coding i would like to define the variable holding the hyperlink with my shared_method.vb.
I have:
Dim hl_back As HyperLink = CType(Master.FindControl("hl_master_back"), HyperLink)
This works within a page but not within shared_methods.
I have the following code which at the moment sits in a number of pages:
[Code]....
It sits in the page because I reference the usercontrol type 'emailSignUp' and pass data to an exposed variable 'DisplayType'. The control is located in the pages master page. Ideally what i'd like to do is put this in its own class or something, so I can just call it passing the configuration variable, but I'm unsure how this would work -
