Asp.net - ObjectDataSource.Select() Not Always Firing On Page Postback

May 15, 2012

I have a form with:

[Code]...

Whenever I change the value of MyTextBox and press MySubmitButton, the select method of MyObjectDataSource is invoked and everything works OK. But if I change the value of any of my check boxes (without changing the value of MyTextBox) and press MySubmitButton, the select method is not invoked, thus the "MyObjectDataSource_Selecting" event doesn't take place and I get the same results as before.

One way I found to work around this was to explicitly invoke MyGridView.DataBind method whenever MySubmitButton was clicked. Is this the best way to handle these type of parameters? What I am afraid is that this may cause the select method to be called twice making the page slower.

Force An ASP Page To Postback?

Feb 18, 2009

I've got a handful of dynamic controls populating an ASP page, with VB.NET in the back-end.What I need is when the user changes the .TEXT value of a textbox and the page posts back, the .TEXT value of a Table Cell changes to reflect that change (it multiplies the value of the textbox by the value of another cell).But a Table Cell can't be set to AutoPostBack, and I can't for the life of me figure out how to programmatically refresh the page (force a postback) in the TextChanged event for the textbox.

.net - Usercontrol And Page Postback?

Aug 8, 2011

I have a page with three radio buttons and a calendar usercontrol. The radio buttons have autopostback and depending on which one you click it should change the calendar availabilities based on the selected index.The problem is that the page load of the calendar is executing first before the selected index change (where I am setting the needed id).

Asp.net - Dropdownlist Is Cleared On Page Postback

Apr 8, 2011

I have a FormView bound to a SqlDataSource on my page. One of the controls on the FormView is a DropDownList, which gets populated on Page_Load (it's being populated with a list of file names from a specific folder).

Everything goes well when the page first loads. I am able to view the list of files, select one and, upon hitting the "save" button, store the correct filename in the database. However, when the page refreshes after the post back - the DropDownList is empty.

Losing Most Of The Page Content On Second Postback?

Jul 5, 2010

I have a form with a update panel. This posts the form and validates it. Returning a errorMessage string of any invalid field such as "Field xyz is a required field, Field abc needs to be a quantity" When I enter incorrect date it posts back fine and displays the text in a div at the bottom of the page which the update panel is aimed at to update. (and only this it should be changing)This works but the second time I hit say (say i enter invalid data twice) the Complete form will disappear leaving me with just the banner of the site and the error message that is returned.

Prevent Page Scrolling After Postback?

Apr 13, 2012

I am working with adding up user's scores based on their checks in a CheckBoxList. Every time a user checks a box, a value, X, is added to the overall score. When a user unchecks a box, a value, X, is subtracted from the overall score. No problems here.

The problem that I am having is that using the AutoPostback option in the CheckBoxList properties forces the page to load back to the top instead of staying where the user was situated, which means that they have to keep scrolling down after each check/uncheck. Is there a way to prevent this?

Getting A Cancelled Postback That's Causing A Page Load Error

Sep 23, 2011

when I clicked the send button it would work, but if you tried to hit enter it would just do a postback to the same page. Yesterday I thought I finally got it so it would work on chrome (it has been working just fine on firefox, but breaking on chrome/safari and it is an app for the iphone). But, even though I finally got it so it would change pages, it is now displaying an error. I narrowed down the cause to a postback that is being called right before the postback I want is being sent which is then cancelled. I assume the cancelled postback is blank because the problem I was having was the page would do a blank postback.[code]

Reading 'Checked' Property Of Dynamic CheckBox On Page Postback

Dec 29, 2009

How can I check the 'Checked' property of a dynamically-created checkbox during the Page_Load subroutine? Basically, I have a VB.NET page that creates some table rows dynamically, based on a number selected by the user. So, for example, if the user selects "3" from a dropdown list, the page posts back and creates three table rows. Each row contains a couple of textboxes, a dropdown list, and a checkbox (which are all .NET form controls rather than plain HTML controls, I should point out).Typically, the user would enter a few details into the form controls, and click the 'Submit' button, after which the page iterates through each row, and inserts the data into a SQL Server table.But if the user ticks the checkbox for that row, this signifies that the page is to ignore that row, and NOT insert that row of data into the database when the user clicks 'Submit'. This works well, but there is a problem. If the user clicks 'Submit' and some of the values entered into the form controls are invalid (so, for example, the user didn't enter their name) then the page won't submit the data, and instead, shows an error to the user informing them of the values they need to change. But if the user creates three rows, for example, but decides to "ignore" the third row (by ticking the checkbox) then when the page posts back, finds some invalid entries, and re-shows the form to the user to allow them to correct any errors, I'd rather the page didn't render the third row altogether. After all, they chose to create three rows originally, but then decided that they only needed two. So it makes sense that the third row is not recreated.

But what seemed to happen was that objCheckbox.Checked was always returning False, even when the checkbox was ticked. Once the page had loaded, the table rows had rendered again, and the tick was present in the checkbox, so it's not like the value was lost on postback. But at the point I check whether the checkbox is ticked, it always returns False, rendering a table row that the user doesn't need.Does anyone know how to get round this problem? I've read lots of articles about the .NET ViewState, and the page lifecycle, but I've yet to find a solution that works. I simply need to be able to check if a checkbox is ticked before re-creating some dynamic controls. [code] But then I basically found out that you can't override a protected member with a public one.

Prevent Button Serverclick Firing On Every Page Refresh?

Feb 22, 2012

prevent a button serverClick event from firing on page refresh?

Markup:

<INPUT id="btnGo" type="button" value="Go" runat="server">

VB.net:

Public Sub btnGo_ServerClick(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles btnGo.ServerClick

The btnGo_ServerClick function needs to fire on the button click, but not on page refresh.I've tried using IsPostback, but that is always true- even on the button click.N.B. I'd rather not go into the reasons behind why I'm using a serverclick, rather than an asp:button and a click event. Suffice to say it just isn't suitable for I am doing.

Form With A Tab Control That Has 18 Pages - Click On A Tab It Opens The Page And Select A Textbox On That Page

Mar 8, 2009

I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

ASP.NET Custom Validators - Page.Validate("groupName") Not Firing?

Jan 5, 2011

I have a custom validator in which the script validating the control is client-side javascript. In my VB code behind for the website I call Page.Validate("groupName") but my validation script is not fired at all. I placed a break point in my javascript, but it's not even touching my validation script. While when i use the same function on non-custom validators it works.

I am thinking that it is impossibly to call my client-side validation script in my VB behind code via Page.Validate("groupName"). Do I absolutely need a server-side validation function?

Here's a bit of code:

Building A ASP.NET Profile Wrapper To Use With An ObjectDataSource Control?

Dec 26, 2011

building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.

Namespace SiteMemberShip
Public Class ProfileWrapper
Private FirstName As String
Private MiddleName As String

IDE :: Pass Parameters To Stored Procedure Through ObjectDataSource?

Jun 7, 2007

I am building a three tierd app, and therefore have all my data access methods in a class by itself.This class only calls stored procedures, basically, I need to pass in the following:

1) stored procedure name as string

2) parameters as IDataParameter() -- an array of parameters

3) other fields ( not important to this discussion)

If I use a GridView on my web form and choose an ObjectDataSourceObjectDataSource, and then choose my business object and method, since the method is a call to a stored procedure with a parameter array, I don't know how to pass it values in the IDataParameter format.The Method Signature listed on the wizard is "RunSP(String spname, IDataParameter[] params), returns SqlDataReader" which basically is calling a method called RunSP with two parameters, of which the second parameter is a parameter array for a stored proc.
