i have following issue: I am creating a new user register form manually without CreateUserWizard control, and all works perfectly unitil I intentionaly (for test purposes) enter existing username (for example BLABLABLA) into username.textbox. After that i get my error message as expected that says "username BLABLABLA allready exist", now when I tray (as a future user who could be in the same situation) to correct the username and enter another one (for example TRATRATRA), it still gives me this error "username BLABLABLA allready exist!" This is the second day that I'm traying to solve this!

I have to access the parent form's controls inside an event handler method on my user control's code behind.
View 4 RepliesI have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?
I've created a multiple uploadfile user control - upload_multiple_files.ascx:
[Code]....
which has an update panel ID = up_upload_multiple_files this user control will be placed inside a modalpopupextender. My question is when I click in any button AddFile, RemvFile, Upload there's a postback so the page is reloaded and the modalpopupextender disapears Is there a way to to troubleshoot this?
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->
I tried this but no luck!

I have created a Templated User Control (see:

I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.
how to find Textbox Control inside DetailsView Control Using Javascript, I tried below but gives an error OBject reference not found
document.getElementById('<%=DetailsView1.FindControl("TextBox1").ClientID%>');
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?
I am working on Social Networking Website. My problem is that
when new user will register he/she will get Pre-designed Profile page from where user can update profile.
This is what I have in the RegisterUser.aspx and yet when the admin registers a new user, then on clickiing the register button, the site logs in as the user who was just created.

I'm trying to use this [URL] methods to localize web user controls, but it doesn't work. Is there some trick for web user controls?
I am using a usercontrol which has two textboxes named txtUserName,txtPassword and a button named btnSubmit.I am using this usercontrol in my webpage.I want to show alert message in the webpage if the user didnot enter the username or password .
View 1 RepliesNow the weird thing is I have a user control UserControl1 in which I put some JavaScrdipt logic there, and I have another user control UserControl2 and I registered both in the page called Page1.aspx.I would like to call the JavaScript function resided in UserControl1 from UserControl2, however, I got an error saying the function is not defined. I think both user controls are loaded before I use them then I think the JavaScript function can been seen anyway in that page.
View 1 RepliesI think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs.
As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup. The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using...
ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False)
... which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
I have a UserControl, ASPX page, a Class file and a JS file. In Class file, I have a method for building and registering textbox controls:
ScriptManager.RegisterClientScriptBlock(this,
typeof(Page),
"onfocus", jsText.ToString(),
true);
jsText is nothing but Name and Value pair strings. Example : "KEY1:txtName, KEY2:txtDOB" In UserControl, I am calling the above Class method to pass all the textboxes and calling the JS file to validate the registered controls. Then, I am calling that Usercontrol in ASPX page. Here I am unable to validate the controls as it is saying "KEY is undefined".
I have a treeview in a user control. I need to run a javascript function with every asynch postback to scroll the div it's in to the right position. I've got it working, but I think there has to be a "cleaner" way to do it. In the Page_Load function of the control, I have the following code. Is there a better way to do it?
ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "key" + DateTime.Now.Ticks, "RestorePosition();", true);
For the benefit of anyone searching for this answer, here is what I finally did that worked. At the top of the ascx page, I have the following code:
<script type="text/javascript">
function pageLoad(sender, args) {
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(SavePosition);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RestorePosition);
}
function SavePosition(sender, args) {
document.getElementById('hdnScrollSaver').value = document.getElementById('reportTreeViewdiv').scrollTop;
}
function RestorePosition(sender, args) {
document.getElementById('reportTreeViewdiv').scrollTop = document.getElementById('hdnScrollSaver').value;
}
</script>
And then I wrapped the treeview in a div tag as follows:
<div class="reportTreeView" id="reportTreeViewdiv">
<asp:TreeView ID="TreeView1" runat="server" OnTreeNodePopulate="TreeView1_TreeNodePopulate"
OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" PathSeparator="|" SkinID="ReportTreeView" />
</div>
