Forms Data Controls :: Listview Cancel Command Button Not Canceling After E.Cancel?
Oct 28, 2010
I am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?
I have a text box that I am reading mulitple employee names into. If the user enters a name that does not belong to an employee I want to cancel the item_updating function. Here is my code:
Dim RECIPIENTS() As String RECIPIENTS = RLIST.Split(";") Dim NAME As String [code]...
I'm using a datapager control on my listview to perform paging in it.When paging through the table, I need to perform some validations. When these validations are not successfull, the paging should be cancelledI currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.
i want to update the values of the rows on my gridview. there are no errors or warnings about the code, but when i debugged the project i saw that the textboxes i want to change do not change. so there can not be update process.
Trying to add some custom code behind the cancel button built into a details view. How would I go about doing this?This is what i have currently. But, when clicked, the cancel button does not pick this up.
I have a detailsview which has a button for insert and edit depending on mode plus a cancel button. What I am looking to do, is to use the cancel button to stop any insert or update to the database if clicked.
I have a page on which I have two forms, which really act as a main form and a subform. I can put a Cancel button (which removes any inputs I have made in the form) on each form. But I want to put just one Cancel button that Cancels the input for both forms. I know that there is a Form.UpdateItem, Form.InputItem, and Form.DeleteItem, but I can find no Form.CancelItem. Is there a way to emulate the Form.CancelItem programmatically?
I have two buttons: Save and Cancel. I have set CauseValidation = "False" for this cancel button. But when I click the button for the first time, it still causes validation while it does not cause validation if I click it again.
I tried to fix it by defining validation group for all validation controls, controls that are validated, and save button. But still the cancel button would validate when first time it is clicked.
In a VS 2005 C# web app, I've implemented change monitoring, so that if the user clicks the Cancel button after having changed the value in one or more controls, they are presented with a dialog box in which to confirm that they really want to discard the unsaved changes. I've set up a utility class, which includes the code shown below. Each of my edit pages inherits from the utility class, and in each of their Page_Load() methods I include a call like this:
EstablishCancelConfirmation(btnCancel, "Data has changed - OK to cancel and discard changes?");
i am doing simple login page and i used to required field validator to validate use now i want to redirect this page to home.aspx after clicking on cancel button, but that two required fields validator get pop up and i get stuck in login page.
How do i display a message with Ok and Cancel in a datagrid view click button
Protected Sub grvCarBooking_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles grvCarBooking.RowCommand If e.CommandName = "Closed" Then Dim Index As Integer = e.CommandArgument lblBkID.Text = grvCarBooking.Rows(Index).Cells(0).Text
I am a total newbie here. I have generated a web page using Visual Studio 2008. It connects to a database and lets me insert records. On the bottom of the form it automatically pus a link for "Insert" or "Cancel". I need them to be buttons. Is this possible? I don't even know where to begin.
with a commandName="confirm" and its CommandArgument the memberid from objectdatasource. I have create a code behind to put certain action to the said button..
[Code]....
But it has no effect. Did I make some mistake? I'm still new in this ASP.Net things.
I'm still building). After loggin in, users are presented with 3 radio buttons (they work), and 3 cascading drop downs (they work). Below that is an AJAX Accordion with 5 panes, each pane has a tabpanel with 4 tabs, 2 of the tabs have gridviews that change based on who is logged in and the radio buttons and dropdowns above
It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
Im going to attempt to explain this as short as possible.I have a student registration page.There are two ways you can add a new student:1)'Add New Student' button in the emptydata template field of a detailsview )When the detailsview is actually populated just click the 'insert' linkProblem is I need two cancels buttons that do different things depending on which scenario above is enacted. I tried to state: When "Add New Button" is clicked show one cancel button and not show the other.I have both cancel buttons showing as of now, and they are both setup to do the different things that I want them to do just cant get them to be visible or not visible depending on which button is clicked.
As I allow editing of row, so I have GridView:RowUpdating(). In it, I check if the entered value is valid. If not, I have e.Cancel = true.
[Code]....
After I see the message box comes up, the textbox still stays the same. I expect the textbox will disappear just as if I have pressed the Cancel button. (By the way, the ClientUtil is a class someone has written for me.)
How do I make the e.Cancel = true works as if I press the Cancel button.
I have a LoginView element in an Update panel and use JQuery to hide the div containing the update panel when the cancel button(Html) is clicked.
It works fine normally. However, when I enter an invalid password and there is an error message displayed, the Javascript attached to the Cancel button click stops firing.
I have a cancel button on a number of steps which when clicked allows the user to exit the wizard. However, I have a few steps that use the RequiredValidator control, which when the cancel button is clicked these validators are also fired. Also I have these steps inside User Controls as a oppose to being on one page. How do I stop these validator controls from firing when the cancel button is clicked?
