View 1 RepliesIt 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.
View 2 Repliesi duno why, when i put a autopostback in my drop downlist, after the postback, my content HTML editor and the flash button all disappear.
i have put the enable view state = true. but it still happen.
I have a checkboxlist with autopostback set to true, the checkbox list inside a panel and together they are inside an update panel.
when I first check one item everything is fine but when I try to check another one a javascrip error fires.
"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Specified argument was out of the range of valid values. "
this is my code:

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.

Am using DropDown list. Whenever Autopostback is true it selecting first value of dropdown list...
View 1 RepliesMy dropdownlist having data from database added with the following item:
DropDownList.Items.Insert(0, new ListItem("Please select", "0"));
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.

is there any way to fire this onselectedindex change event on blur or on enter key press...is there a way of doing it with java script or jquery...
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 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.

Buenos nachos, to be brief, my question is: is it possible to allow users to add new items to a combobox at runtime without having the autopostback property set to true? I understand it needs to postback if a new item is added, but I do not want the box to postback if the user simply selects a different value!
The tag I currently have is below. Without having the autopostback="true", the comboxbox doesn't allow the user to add new items to the box >_<' Any thoughts?
<ajx:ComboBox ID="cbCompany" runat="server" Width="226px" DropDownStyle="DropDown"
OnItemInserted="addCompany" AutoCompleteMode="SuggestAppend">
</ajx:ComboBox>
I know I could add a few more controls and do an easy workaround, just wondering if it is possible to do it this way.

When I change the value in dropdownList (in browser), it does PostBack, but it selects the first item of list after PostBack - it doesn't save my value.
GetAllDepartments(isDeleted) is a stored procedure, it returns a List of objects with two properties - FieldKey and Name.

WebuserControl holds a button that trigger a database operation. As soon as I click on button inside webusercontrol the whole control disappears, leaving behind a blank modalpopupcontrol. Remember there is no postback happening as modalpopup has updatepanel as its first child. Everything is inside this updatepanel.
I have several input pages where I autopostback is marked "True", when I enter the data or select the entry. The page flashes a losses its normal tab sequence. How can I mainatin teh Tab Sequence (focus)? Exmaples

I have a AJAX editor and I want to put the HTML content in a database and I want to get the HTML data from the database to put in the HTML editor, in HTML mode.
So I do:
Editor1.ActiveMode = AjaxControlToolkit.HTMLEditor.ActiveModeType.Html;
I'm using ASPMaker to create a content site editor. It analises the database and creates automatically the pages(list, edit and add) for all DB tables. But ASPMaker is limited to customize the resources and design.
I need any easy and fast way to create this content editor in ASP.Net C#. Can someone indicate a software or any easy way to use Visual Studio 2008?
I went through the documentation and looked at the asp.net/webmatrix pages but could not find a RichTextEditor.
Is there one built into WebMatrix or can I just use the AjaxToolkit Html Editor or another 3rd party editor?
