Forms Data Controls :: Details View - Blocking Multiple Clicks When Updating?
Mar 12, 2010I have a problem that is driving me insane. I have a simple detailsview that operates as you would expect a detailsview to do - the only difference being that in the updated event I send an email to various people to advise of detail changes (I have conditional testing to do this).
The problem is that if the user goes crazy with left clicking the update button, email recipients can receive multiple duplicate emails.
I have looked all over the net and seen many varied solutions for this problem - mainly using javascript - but none of them seem to be able to block multiple clicks without disabling or hiding the update button - which obviously causes issues with client side validation in the event that information is missing or incorrect.

View 10 RepliesMVC :: Ajax Loaded Partial View Form Submits Multiple Times?
Feb 2, 2011I am trying to implement an ajax form inside of a jquery ui dialog.
I have a view with a button that opens the modal dialog form, makes an ajax call to an action that loads a partial view into the dialog. The partial view consists of a form created via Ajax.begin form. When I post the form I close the modal and update a div on my main page. This all works fine.
The problem is, the next time I open the modal and submit the form the http POST for the form is called twice. The third time I open/submit the form is submitted 3 times and so on...
It seems as if the submit button/form is bound multiple times and I cant figure out how to fix this.
Here is my code...
first the jquery call to load the ajax form partial view and create the modal...

here is the ajax form partial view...

Forms Data Controls :: Specify Which Columns Are In A DataView From A DataTable?

// DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view.
// DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.

Forms Data Controls :: Exclude A Row From Dataview Sort?
Mar 5, 2010I have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..

Forms Data Controls :: Export To Excel Using Dataview?

Forms Data Controls :: Populate FormView From A DataView?
Feb 23, 2010Im trying to populate my formview from a dataview in the codebehind and the order in which things are happening is causing it to fail.my formview itemtemplate is setup with some eval("fields") which is initially not populated (nothing bound to it) and the page loads ok. i think click on my graph which generates a query and populates a dataview.i then assign that dataview to the formview and run the bind.what happens when i actually run the app is that it says no data is bound to it.i set the debugged to stop at the point where my DV is assigned to my FV and the FV shows a data item count of 1 (as expected) if i keep stepping it puts me in to the eval statements on the aspx page says the data isnt bound.
the error i get is
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

Forms Data Controls :: Sort DataView Ascending With Nulls Last?

Forms Data Controls :: Change The Visibility Of A Field In Dataview?
Jul 17, 2010I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
