Web Forms :: PostBackOptions In .NET/ The Autopostback Property Is Not Functioning (for True Or False)
May 27, 2010
In the postback option class, the autopostback property is not functioning (for true or false) to forcibly set the the post back event on web page load as defined at the MSDN Url http://msdn.microsoft.com/en-us/library/system.web.ui.postbackoptions.aspx
A client side validation retrieves the GetPostBackEvent reference successully but fails to to load the page as a forced post back event. The options being set are a) ActionURL, Autpostback , RequiresJavaScriptProtocol and perform validation.

Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.

I've got a server control that renders out a series of dropdownlist and a checkbox that all have autopostback set to true. When the control renders the onchange event binding is not written out!
Controls are defined as protected, named and added to the controls collection in OnInit, and rendered via RenderControl(writer). Page.requiresPostback is also set.
ANy ideas why this might be? I'm scratching my head.

I am getting the following error as Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. when an invalid value is passed in dropdown with autopostback=true. What should I do. I want the solution with "EventValidation=true" and "ValidateRequest=true" in the Page directives. Also without any Custom Error Pages Enabled in web.config file i.e Custom Error Pages are off in web.config file.

I have three AJAX sliders and each has a:
<asp:AsyncPostBackTrigger ControlID="Slider1" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider2" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider3" EventName="TextChanged" />
When I do a TextChanged event on slider1 (by dragging the slider, changing the value), the protected void Slider1_TextChanged(object sender, EventArgs e) event FIRES, however, the TWO other sliders, protected void Slider2_TextChange, and protected void
Slider3_TextChange also FIRES. What gives? why do they fire when I am physically only sliding the slider1 across. The two other sliders values did not change on the webform, yet the event fired.
In order for the event to fire for slider1, I had to insert "Autopostback=true" in the <asp:TextBox ID="Slider1" autopostback="true" OnTextChanged="Slider1_TextChanged">. For <asp:TextBox2> and <asp:Textbox3> I did not put the autopostback event for now.

I have two pages for different companies with nearly the same ASPX markup and code-behinds (main alterations include certain fields from the same table being read-only in one and editable in another), #1 has a Select (for populating the DetailsView) and Update while #2 has Insert, Select and Update. #2's Insert and Update functions are not operating while #1's are just fine... I've gone through optimizing #2's codebase and I for the life of me cannot figure out why it's not functioning properly. What follows is #2's markup and codebehind for the relative functions accessed:

I have the following sample code
[Code]....
[Code]....
When I place a value in TextBox1 and then click inside TextBox3 (which is there to have a place to go to get out of TextBox1 and TextBox2) the value from TextBox1 remains and is displayed in the MessageBox.Show correctly.
When I pick a value from the drop down calendar extender in TextBox2 for a brief micro-second the value from the calendar displays in TextBox2 and then the MessageBox.Show displays and the value in TextBox2 returns back to the orginally set value. The MessageBox.Show shows the orginally set value.
For TextBox2 if I set AutoPostBack=false then the TextBox2 works correctly and keeps the date picked from the calendar extender but the ontextchanged="TextBox2_TextChanged" never fires.

I have an asp:label field for and expire date that should either display "Never" if the database field ([msDS-UserDontExpirePassword] this is a bit - true/false - field) is True, or otherwise display a date (pwdExpireDate).
My code doesn't throw any errors but I can' fully test it without putting it into production. Can someone tell me if this is correct? Also, there is no code-behind and I can't use code behind for this.
Here's the code:
The label: <asp:Label ID="lbUserPWExpireDate" Text='<%# ((bool)(Eval("[msDS-UserDontExpirePassword]"))==true ? "Never" : Eval("pwdExpireDate", "{0:M/dd/yyyy}")) %>' Runat="Server"/>
The query: <asp:SqlDataSource ID="GetUserExpireDate" runat="server" ConnectionString="<%$ ConnectionStrings:USER_PREFERENCESConnectionString %>" SelectCommand="SELECT DATEADD(day, 59, pwdLastSetDateGMT) AS pwdExpireDate, [msDS-UserDontExpirePassword] FROM LDAP_Users WHERE mail = @USER_EMAIL_ADDRESS" OnSelecting="GetUserExpireDate_Selecting"> <SelectParameters> <asp:SessionParameter Name="USER_EMAIL_ADDRESS" SessionField="USER_EMAIL_ADDRESS" /> </SelectParameters></asp:SqlDataSource>

I've got a checkbox where the column is a Yes/No string and I need to convert this to a True/False in both directions. The database exists already and I can't change it or I would just change it to a bit column.
I tried this and it didn't work even in one direction.
