Web Forms :: Validate Control A Depending On If Control B Has Any Value (diff Types)?
Sep 3, 2010
I've ready everything I can find on the built-in validators but can't figure out how to do the sort of validation I need on theclient-side (I can do it on the server-side). Business rule I want to enforce (review the gridview snippet below) is if user checks the CheckBox_EditLifeCycleRpt control but doesn't enter a value in the TextBox_LifeExpectancy control then the validation should fail.
How can I hide a control on a "Web Content Form" depending on what page is displaced.Working example. I have a control on a master page but I want this control to be hidden only when a particular page is loaded.
I have 1 drop down, 1 text field and 1 command button i.e. "Search". Dropdown contrains following values
Type1 Type2 Type3
In textbox user will enter numeric or alphanumeric value
Here I want to check if 'Type1' is selected so user can enter only numeric value between 1000 and 2000, otherwise display some message "Entered value is not valid for "Type1". I want to display this message thru required validator error message property
If user select 'Type1' and 'Type2' then user can enter any alphanumeric value other than 1000-2000 numeric range.
I want to implement thru Search button or once user leave the textbox after entering value. Here I want to display message.
trying to restrict the "Administrator" from deleting the product when the product is still "Available" or "unsold".When a user buys the product the status will become "Sold", and when the product is not sold, the status will be "unsold". i want to do a validation where there will be a prompt when the administrator tries to delete the product that is "Available" or "unsold".
I've tried many ways by using OnItemDeleting to create the prompt, but it didn't seem to work together with OnItemDeleted. The record will remain in the database even when deleted or there the prompt is not working. Please tell me how do i go about doing the OnItemDeleting when the status changes. Or is my method wrong.
This is my code for the DetailsView
This is my code for the OnitemDeleted [Code]....
I have tried to validate using OnitemDeleting together with OnItemDeleted(using the previous code above) to restrict the quantity before. But it didn't work.
I have an asp.net 3.5 WebSite application where I have a bunch of UserControls.
In some scenarios I have a reference of type Control (System.Web.UI.Control) that I need to cast to a specific User Control type (to access public properties and methods of the User Control).
The User Control classes are all declared in "the global scope", i.e. not within a namespace. However, for some reason, only some of my User Controls is possible to type in a code file and show up in intellisense and some just wont. In one scenario I could write the cast in code anyway and the site would build (but the UserControl type name did not shift in to the ordinary class name color (light green, you know) in VS text editor), but when running the page I still get the error message about missing using directive or a reference...
If I use the VS 2010 "Navigate to" feature (Ctrl+,) and search for a type I usually get one hit for the Type/Class name and another for the actual file. When searching on my User Control class names I only get the file hits, no class representation. This even goes for those User Control types I actually can access in code.
I've tried to compare the User Control classes that work and doesn't work, but I can't find any difference, they are all declared as public partial.
I have a Menu control in MasterPage based on web.sitemap file. My website has roles enabled (AspNetWindowsTokenRoleProvider) and uses Windows authentication mode. So, user has to be in a specific Windows Group to be able to access the site. I need to allow some users to see all menu nodes and some restricted set of nodes. How do I do that?
I would like to be able to create, say following Windows groups:
I have an aspx page that references a server control from an assembly and lives in Sharepoint (knowledge/experience in Sharepoint is not required to answer this question, i'm simply giving you context). The implementation looks something like this:
I can NOT change the .aspx page's content which currently lives in Sharepoint and I have to to take the same code and run it outside of Sharepoint but still on an ASP.NET environment. It's cool and crazy at the sametime, I know.
When this aspx page is running in Sharepoint, I have to get the WYSIWYG editor control to use Sharepoint's WYSIWYG control. When the same aspx page is running outside of Sharepoint but still in an ASP.NET environment, I need it to use a different server control that's not dependent/from Sharepoint. How could I modify the code-behind to perform this toggling? Is this even possible?
I have a with dynamic values from an Enum like: String, Int, Double, Bool, DateTime.How do I create a new Control depending on what is the SelectedValue dynamically into the page? I want a CheckBox for Bool, TextBox for String, Calendar for DateTime etc.
i have two controls in one page, grid control and a form control, inside the grid control there is a textbox control. my question is when ever click update in the gridcontrol, the validation control in the form control get fired and the page does not post to the server.
How can i make a control required to put input depending on the radiobuttonlist selection? Let me try to clarify a bit more. I got 2 radiobuttons, if one gets selected, nothing else has to be done. But if the otherone gets selected, a textfield must have some input too.
I am running the code below in a .net 2.0 content page.There are no containers such as wizard etc. When I click on the submission button for debugging purposes I get 'Nothing'. why I can't access the 'controlToValidate'?
Protected Sub validateCharacter(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) If Page.IsPostBack Then Dim validationControl As CustomValidator = DirectCast(source, CustomValidator)[code]....
I have a grid with checkboxes on each row. If the user checks a box then clicks the delete button which is not on the grid, that row should be deleted. Here's the problem:When the page opens the user can click the delete button and crash the problem. How can I disable that button till at least one checkbox is clicked (true)?

I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.
