I have a ASPX page that loads a custom control. This first custom
control is made up of 2 textboxes and a Submit button. The user enters
data into the form, presses the Submit button and the ASPX page should
either load a new custom control during the postback or (if validation
fails) reload the first custom control. I've attached some validation
controls without a problem but the client-side validation doesn't seem
to be working...even in IE with Javascript enabled.
Does anyone have any suggestions? Thanks! 4 2030
ASP.NET pages expect you to create the same list of controls on post back
that you sent to the browser originally. This allows the post back code
distribute the data to those controls and fire their events (including
Click, TextChanged, and validation). It sounds like you aren't setting
things up the same on each pass.
I recommend this:
Load both UserControls. Change their Visibility. On the first pass,
UserControl 2 should be invisible. On the second pass, during the Click even
method, first test that validation was OK (Page.IsValid=t rue), then change
the visibility of these Usercontrols.

I don't think that'd work out too well in this case as the first page
(or control view, really) displays a form that prompts the user for
input parameters (i.e., "Select a year", etc.). After postback and
validation, I'd like to use a second control to create a user-specific
report based on the input parameters.
I don't know...maybe I need to rethink the site architecture.
I'd check the span tag or whatever html is created for the validators
and make sure their controltovalida te ID values match the textbox ID
values. If you are adding controls too late or and setting IDs on them
manually it could screw this up.
Bascially you can debug the validation javascript yourself and see
where its stopping. Its not that hard. Put a breakpoint in
Page_ClientVali date (in WebUIValidation .js in c:\Inetpub\...) and
follow it urself. Also make sure that the call to Page_ClientVali datie
is being executed in the submit button onclick handler or wherever it
is in the html page.
Sorry I don't have exact details but its kindof late :). You can debug
this yourself i've done it many times.

Hi,
I have the need to use dynamically loaded user controls in a webform page.
I have the controls loading dynamically, and that part works fine. this is
the code used in a webform to dynamically load one of several controls:
private void btnCategory_Click(object sender, System.EventArgs e)
{
Control myControl = LoadControl(DropDownList1.SelectedItem.Text +
".ascx");
PlaceHolder1.Controls.Add(myControl);

PROBLEM:
When a user control is loaded into a PlaceHolder control more than once, the
events do not fire on the first click of a control on the dynamically loaded
user control. In other words, the first time the control is dynamically
loaded, everything works fine. After that, if the control is loaded again
from the page button event handler, the user controls events fail to fire on
the first click

Hi Everybody,
i want to load dynamically content from some user controls (with forms,

the user control into a placeholder.
Using buttons for loading new content works fine. But i still want to
use a function which is callable per javascript. I think this way is
more flexable than using the Buttons, becaus every button needs it's
own Sub-Routine. But i want to have...
