Web Forms :: Clear The Contents Of Wizard Between Calls And Without Url Redirect?
Mar 31, 2010
I have a complex page which has a series of panels and buttons.
one of those buttons pulls up an a wizard control.
the user does not need to go to the finsih button of the wizard if they wish to cancel the wizard.
What I want to do is to clear the values of a wizard as it is being called by a button click.
Uncle google tells me a solution is to use a URL redirect to effectively reload the page into memory. This would also destroy the view state of my page for the nonwizard controls which I dont want to do.
I cant put the wizard into an Iframe (company policy) so I cant just reload the iframe.
I dont want to go step by step and control by control to clear the values - Also the wizard is not using databinding.
I am making multiple calls to ObjectContext.ExecuteStoreCommand with different commands and different parameters, although I use the same parameter list (object) for a several of the commands. I am getting the following exception:
System.ArgumentException: The SqlParameter is already contained by another SqlParameterCollection.
Is there a way to clear parameters between calls as I would do with straight up ADO.NET?
Updated with a code sample:
string sqlDeleteWebUserGreen = "delete WebUserGreen where WebUserId = @WebUserId"; string sqlDeleteWebUserBlue = "delete WebUserBlue where WebUserId = @WebUserId"; var argsDeleteWebUserXref = new DbParameter[] { new SqlParameter { ParameterName = "WebUserId", Value = user.WebUserId } rowsAffectedDeleteWebUserXref += base.context.ExecuteStoreCommand(sqlDeleteWebUserGreen, argsDeleteWebUserXref); rowsAffectedDeleteWebUserXref += base.context.ExecuteStoreCommand(sqlDeleteWebUserBlue, argsDeleteWebUserXref);
UPDATE
Basically I am unable to find any better way of doing this, so I ended up accepting the answer below. The only difference is that I simply put the creation of the parameter into a separate method, so my calls look like base.context.ExecuteStoreCommand(sqlDeleteWebUserBlue, MethodThatWillGiveMeTheParameterArray());
I have a modalPopupExtender which I activate using the showPopup script that is shown below:
[Code]....
I use another script that does a webservice call and fills the popup with the results using innerHTML. The showPopup and webservice function are called at the same time and the modal pops up and is filled with the results from the web service
I use clrPopup function to to try and clear and then close the popup. I want to clear the contents of the div before it's closed. Why doesnt the clrPopup() function above NOT seem to be working? The popup closes but if I open it with a standard asp linkbutton (the one that the modal is actually hooked to) instead of a using the javascript link which I wrote, then the contents from the webservice call are still there...like $find('MainContent_ModalPopupExtender1').innerHTML = 'Fred Flinstone'; was never successful?
I have an HTML Editor in a modal popup triggered by a link on a detail page. The Editor can be used multile times in the same session. If a user adds content and then saves it all is ok. If he the selects to add more content the text from the previous attempt appears in the editor.
I am using CreateUserWizard control on my admin page.After successfully creating a user with the control, it displays "Complete Your account has been successfully created."After clicking on continue button it sets the ActiveStepIndex Correctly.The problem is, while it sets the ActiveStepIndex correctly, it retains the old user account credentials.
For some reason it seems as though variables that I declare in javascript sometimes persist themselves across applications even when I do a response.redirect. I thought that a response.redirect would clear them out.
The above code is my register wizard code, user can register just fine.When the user finish registration, there is a "Continue" button on the complete step.Clicking it will do nothing, how do I redirect the user to specific URL when the user click it?
I have create user wizard control and i put validation control for all field but when i close user control that validators dint clear in firefox or but clear in IE
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?
I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.
i want to get the contents of a textbox and set them to a asp label for output, we can cause a postback to if that makes it easier, so far i did this and it comes up trumps

I know MVC controllers are quite good at serving JSON formatted AJAX requests, but is there any built-in ASP.NET functionality I can use for these type calls from a plain old web forms site
I am currently developing a project management application using ASP.NET (VB). I am nearly done with it. But whenever users select an item from drop-down list control, a post back is triggered and screen is returned to the bagining. This is very irritating at times.
So, I want to know how can I make partial postbacks so that page is not refreshed again and appropriate binding of list control with my oracle database is also made.
I'm using ASP.NET 3.5 and C#.I load an SqlDataSource into a DataView on my Page_Load event. My SqlDataSource queries arandom record from the database. On my page I have an ImageButton, which when clicked uses a Response.Redirect("AnotherPage.aspx + "random id from database"). My problem is that when the button is clicked it fires the Page_Load event before the Response.Redirect takes place in the button_click event. This causes the current data(the users "id") that I had pulled from the database to be overwritten with new data(a different "id") from the database. So essentially the the page is redirecting to the 2nd random id that is queried from the db after the button is clicked and Page_Load is fired again, not the original id. Here's my code, hope it makes sense.Here's my Page_Load:
Can I put my dataview in another event or method so it's not called when a user clicks an ImageButton. Also I want the DataView to be repopulated on a postback/page refresh, just not on button clicks.
