View 8 RepliesI am trying to build a form that will not change the URL in the users browser, and will not allow the user to press the browser back button. Is there something I can do to accomplish this?
E.g. Form 1
Url: MyForm.aspx
Form 2
Url: MyForm.aspx (still the same url)
I'm using the built-in ASP validators on a few form elements. They work fine - if I click the submit button (a Button), validation occurs without postback and errors are displayed in a ValidationSummary. When that occurs, I also want to call a method in codebehind which changes the CSS of elements, switching their background color to red to reflect errors. I've tried to call this method using both OnClick and OnClientClick in the submit Button, but neither parameter seems to fire the method - client-side validation always takes priority, and a postback never occurs. Can anyone enlighten me?
EDIT #1 Using orandovs link worked alright for changing the element itself, but how about its parent? For example, in C# I'm doing:
foreach (BaseValidator validator in Page.Validators)
{
Panel panel = validator.Parent as Panel;
if (!validator.IsValid)
panel.CssClass = "error";
else
panel.CssClass = "normal";
}
Is there a way to get the parent control (which are all consistently Panels, so I know CssClass will exist) using JavaScript? Something like: $("#" + Page_Validators[i].controltovalidate.parent).CssClass("error");
Basically, I have a user control with a set of input controls such as textboxes and radio buttons. It also has a button along with these controls. What I want is that when the user clicks this particular button, the data entered in the input fields must get updated into a grid in the parent page.

View 1 RepliesI have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:
<asp1:Object id="objectMain" runat="server" OnClick="Click" />
Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?

I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

I have a user control that has several data components
What I want to do is populate the data components based on the parent's page title where the user control is called.
The parent page title is the most logical unique name to each page and so that would be the name that I want to import
as the default value for the data components select parameter. Each page name is stored in my sql data table [Towns] as TownsName.
The general idea is that the control will populate with the towns data based on the page title of the parent page.
<SelectParameters>
<asp:ControlParameter ControlID="DetailsView3" DefaultValue="PAGE TITLE NAME GOES HERE" Name="TownsName" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
I am not sure how to code this correctly, but I am sure it would have to be called in the page load statement.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SetAttr(DetailsView3.DefaultValue = Parent.Page.Title())<-------THIS OFCOURSE DOES NOT WORK
End Sub

View 35 RepliesIn my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?

is there a folder dialog control in asp.net?i ). i tried using the input in this way:
<input type="file" runat="server" id="d" />
but it enabled me to browse a file and not a folder.
Whatever server Control we take on aspx page while in coding phase, all those controls are converted to html controls through the asp.net engine and sent to the requesting web browser. That's fine.
Now, all the controls that are rendered on the browser are html controls. I am bit confused that how after pressing any button (Or any such control that post back pages) page is posted back to the asp.net engine. How such html controls comes to know where (address) they have to go?

View 1 RepliesI am using a user control that I created (just a .cs file not an .ascx file), that does some magic and depending on a value generated by the control, I need it to do something on the parent page that is 'hosting' the control. It needs to call a method under certain circumstances (method is on the parent control).the control is placed on the parent page like so:
<customtag:MyControl ID="something" runat="server" />
I'm dynamically creating buttons etc on the control itself but when a button is clicked, let's say for example that there's a text box on the control and if the value of the textbox is "bob" it needs to call a method on the page that's housing the control...how can I accomplish this?
when press back button the previous page control value erased..but I want the control value should be visible.
