Forms Data Controls :: DataList - Updates Show Original Values Not Updated Values?

Jun 3, 2010

Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.

Here's the code for the Item and Edit templates. The code behind is below this.

MVC :: Keep Values Of Model's Unused Members During Updates?

Apr 2, 2010

suppose our model has a property named "CreatedByUserId" that keeps the creator's user id

when we want to update our model, there are no need to display this field, but we should keep it's value during the update.

so, if i don't place any edit field for this property on the view, the model wouldn't have any value for CreatedByUserId property when returns to controller

to solve this, i :

1.place a hidden input in the view for these fields (which is vulnerable)

or

2.make a Get call to db and get the original CreatedByUserId value on each update (which causes additional round trips to db)

isn't there any better way to do this ?

Security :: How To Retain Querystring Values In ReturnURL

Oct 21, 2010

I've got a couple pages in my web app that are used by external applications. They will link to the pages, and pass in various querystring values to allow my app to do the searching and return the results in the page. The problem is, if the user is not yet logged into the web app, they are sent to the login page, and the ReturnURL is truncated to include only the first QueryString value. I lose the rest of the values. So far I haven't figured out a solution to this. Here's a quick example:

The external application links the user to:
[URL]

If the user is not logged in they are sent to the login page, and the current URL looks like this:

Ajax - Implement Real Time Updates?

Feb 27, 2010

I have seen several websites that show you a real time update of what's going on in the database. An example could be. A stock ticker website that shows stock prices in real time Showing data like "What other users are searching for currently.." I'd assume this would involve some kind of polling mechanism that queries the database every few seconds and renders it on a web page. But the thought scares me when I think about it from the performance standpoint.

In an application I am working on, I need to display the real time status of an operation that a user has submitted. Users wait for the process to be completed. As and when an operation is completed, the status is updated by another process (could be a windows service). Should I query the database every second to get the updated status?

Forms Data Controls :: Retain Values In A FormView When Validations Fails Or The SQL Fails On An Insert?

Oct 6, 2010

To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.

As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.

I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.

AJAX :: Updates On User Control Not Available On Housing Page

Jun 27, 2010

I have a user control that I am explicitely calling from an aspx page. In page_load of hte aspx page I have the following, myControl = (DynamicTable)Page.LoadControl("../inc/DynamicTable.ascx"); Then in my code where I want it to execute the control, I have this pnlESDDEnrolled.Controls.Add(myControl); where pnlESDDEnrolled is the panel I am loading it into for display. So, I execute the aspx page, it links off to the user control, populates the control, returns back to the aspx page and the page dispalys with the user control in the middle of it. All is well.

The problem comes in when updates are made on the user control. Keep in mind, that other data is updated on the page as well, and the update button resides on the page, not the control. Anyway, when the update button is pushed, the button_click event is fired on the page, but the updates that I made on the user control are lost. Since the page loaded the user control and then the usercontrol executed the page unload method, the page has no knowledge of the user control anymore. Thus, when the update button on the page is pushed, I guess I am not really sure what happens with the updated data on the user control. All's I know, it is lost.

AJAX :: RangeValidator ErrorMessage Clears When UpdatePanel Updates?

Jan 14, 2010

I thought my issue was related to the Validators not working in UpdatePanels but that does not seem to be the case.

All validators fire when they should but, the error warning message clears when the updatepanel updates.

for example...

textbox1 range 1 to 23. dropdown1 updates the updatepanel. enter 99 error shows, but will disapear when I change value of dropdown1. textbox1 value still 99 so validator message should still show but it does not.
