Forms Data Controls :: Validate Data Using The OnItemUpdating Event On A FormView Control?
Sep 13, 2010
I am trying to validate data using the OnItemUpdating event on a FormView control. The event is fired when I click the update button but
e.OldValues["txtDate2"].ToString() in the function returns a null value. What am I doing wrong here ?
ValidateForm(Object sender, FormViewUpdateEventArgs e)
string val = e.OldValues["txtDate2"].ToString();
I have a user control that displays a list of records. Users have the ability to open an embedded user control with a FormView to either add a new record or to edit an existing one. The UserControl with the FormView has a button that closes and hides the user control.
If the user control with the FormView is opened to edit a record, the code works fine. But if the UserControl is opened directly into Insert mode, the code craps out
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.
I've got a FormView control on a page. Its default mode is insert, since the intent is to have the user enter a record, save it, and then do something else. I've written a stored procedure to insert all of the data into 5 tables. 1 of the columns inserted is default, in SQL Server 2005, as an INT column, which is an IDENTITY column. After it inserts the record into the primary table, using a secondary stored procedure, it retrieves the newly created INT value, and then the primary stored procedure inserts records, using the new INT, into the other 4 tables. This is working fine. The primary stored procedure, which is called by the SqlDataSource on my .aspx page, defines this parameter as an output parameter:
In the FormView's ItemInserted event I'm trying to get the value from the FormViewInsertedEventArgs e parameter like this: [Code]....
However, the result returned is 0. Huh? That cannot be, because the new INT value created is something like 145000. Why am I then seeing a value of 0?
I have two formviews that I want to use together. I want the second formview to become visible based on a value in a textbox in the first formview using the item_inserted event of the first formview. How would I do this? What is the best way? Can I use the Ctype function?
What does work: I do see the right info if the formview is shown but when I click on the Update button it just doesnt fire the corresponding itemupdating event.
Can someone see what is wrong or missing?
What do I want to archieve: Just update the subscription's credits and its type: Upgrade, Prolong.
New finding: I added 'onitemcommand="fvSubscriptionEdit_ItemCommand"' to the formview and a corresponding event method with a simple code that throw a exception(just testing) but it doesnt enter the method but does whine when the method is missing. So why does it whine if the method is not there but doesnt enter the method if it does exist? I presume that this is the same problem.
I have a modal formview with insertitemtemplate. I have to click the insert button twice to fire the event.
But if I do not insert any values, only one click is required and the validationgroup fires. But if I enter all valid values, I need to click twice and the event does not fire during the first click. But I need CausesValidation = false because to required field validators.
How to avoid two clicks to fire the event if the formview is valid
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminsertedevent?
since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
I have 4 checkboxes. I need that user should atleast select one checkbox and then submit the form. But the onClick event of the button is not working. I already have events for button click. See the code for reference.
I am using a form view control which has two binded textbox. Now at this level it works fine and the textboxes show the values from database. But when i insert a panel inside the form view and move these two textboxes inside the panel, they dont show any values. What could be the reason for this?
I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.
