SetFocus to Control From Code Behind with JavaScript

I am trying to set focus to a page control (Textbox) by using the registerStartupScript method. However, I have been unsuccessful. Here is what I have tried:
ClientScript.RegisterStartupScript(this.GetType(), "SetFocus", "<script>document.getElementById('" + this.tbAdjust.ClientID + "').focus();</script>");
And:
ClientScript.RegisterStartupScript(GetType(), "focus", "<script>$('" + this.tbAdjust.ClientID + "');</script>");
Can't seem to get it. Seems like a pretty straight forward question, if you all need anymore code, let me know. Thanks in advance for any help!

Normally tbAdjust.Focus(); at code behind should work. Here are the scripts.
Without Ajax
ClientScript.RegisterStartupScript(this.GetType(), "focus",
"document.getElementById('" + this.tbAdjust.ClientID + "').focus();", true);
With Ajax
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "focus",
"document.getElementById('" + this.tbAdjust.ClientID + "').focus();", true);
If you want to use jQuery, you need # at the front.
For example, "$('#" + this.tbAdjust.ClientID + "').focus();"

Wouldn't jQuery's .ready() method work?
$(document).ready(function() {
$('#target').focus();
});

Try Page.RegisterClientScriptBlock instead:
Page.RegisterClientScriptBlock("SetFocus", "<script>document.getElementById('" + this.tbAdjust.ClientID + "').focus();</script>");

how to preview a html file from database to a browser using C#

I have HTML code stored in a database and would like to display (render) it onto a view.
I wanted to show it as a normal text page.
eg: **HTML:** <h3 style="font-weight: bold">Usage:</h3>
<p style="text-decoration: underline">Viewing of Form -</p>
Should be shown as: Usage:
Viewing of Form -
I have a button as view and when clicked, it should show me the page.
I am using entity frame work so i have written,
string url = ("view.aspx?id = " + page.ID + "&Text=" + page.Text);
ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "window.open( '" + url + "', null, 'height=500,width=800,status=yes,toolbar=yes,menubar=no,location=no,scrollbars=yes,resizable=no,titlebar=yes' );", true);
and i have created a new page view.aspx and tried to use System.Web.HttpUtility.HtmlDecode(Request.QueryString["Text"]) to render the file.
But i am getting a blank page.
Please help me.
Thanks,

Can you confirm that page.Text has a value when it's being rendered?
If you are certain that the value page.Text is populated correctly (I'm assuming something like "view.aspx?id=1&Text=<h3>example post<h3>") then you may want to try encoding the string for the URL before returning it to the client.
string url = ("view.aspx?id = " + page.ID + "&Text=" + System.Web.HttpUtility.UrlEncode(page.Text));
ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "window.open( '" + url + "', null, 'height=500,width=800,status=yes,toolbar=yes,menubar=no,location=no,scrollbars=yes,resizable=no,titlebar=yes' );", true);
Then make sure that you are getting encoded characters in your links on the client.

ScriptManager.RegisterClientScriptBlock problem in updatepanel

Error: missing } in XML expression

line: 0, column: 188
code:
<script language='javascript'>$(document).ready(function() {Sexy.alert( "Can not copy files." );});</script>
CODE:
public static void ShowAsync(string sMessage, MessageBoxTypes sType, Control control, Page pPage)
{
StringBuilder sb = new StringBuilder();
sb.Append("<script language='javascript'>");
string sMsg = sMessage;
sMsg = sMsg.Replace("\n", "\\n");
sMsg = sMsg.Replace("\"", "'");
sb.Append(#"$(document).ready(function() {");

sb.Append(#"});");
sb.Append(#"</" + "script>");
ScriptManager.RegisterClientScriptBlock(pPage, typeof(Page), control.ClientID, sb.ToString(), true);
}
if i change true to false in RegisterClientScriptBlock then i get
error: $ is not defined

i call this popup like:
MessageBox.ShowAsync("Can not copy files.", MessageBoxTypes.alert, this, Page);
What can be wrong. If i copy this (JQUERY)
<script language='javascript'>$(document).ready(function() {Sexy.alert( "Can not copy files." );});</script>
into some .aspx page popup works. But if i call it from code behind and daypilot pro in this updatepanel form then i get this error.
Can be problem that two ajax framewroks mixed themself? How to prevent this?
i try with jquery.noConflict but it is the same
$.noConflict();
jQuery(document).ready(function() { Sexy.alert("Can not copy files."); });
Thx

If you change the last parameter in RegisterClientScriptBlock from true to false it will not add the script tag anymore. Currently with the setting to true, you have the script tag twice. Not sure what happens, but can't be good :-)
$ sounds like jquery? You don't mention what you are using? I mix ASP.NET Ajax with jquery and that works fine. What Version are you on?

Creating a customized "Yes / No" alert box in asp.net (javascript) - Part 2

I am trying to create a customized messagebox using javascript but not getting too far.
string txtConfirmMessage = "On " + DateTime.Now + ", ";
txtConfirmMessage = txtConfirmMessage + sUserID;
txtConfirmMessage = txtConfirmMessage + " added this record. Do you want to continue? ";
btnSubmit.OnClientClick = #"return confirm('" + txtConfirmMessage + "' Do you want to continue);";
I need to display a custom message involving the UserID, the date, and the value that the user has enetered. When I click the Submit button, the messagebox does not pop up.
Update:
I know this code is executed at the Page_Load event. However, is it possible to display in this alert box, a value that the user has selected (that action occurs after the page load event) ?
Any ideas to resolve this issue?

The javascript that you have is not valid, as the "confirm" method taks a single parameter, but you are giving it two bits.
Try this modified version.
string messageFormat = "On {0}, {1} added this record. Do you want to continue?";
string formattedMessage = string.format(messageFormat, DateTime.Now, sUserID);
btnSubmit.OnClientClick = "return confirm('" + formattedMessage + "');";

You just have an extra string after the one you're passing to confirm(), change it to this:
btnSubmit.OnClientClick = #"return confirm('" + txtConfirmMessage + "');";

About the update of the question, you could assign an OnClientClick event handler to the button as late as PreRender and the value will be persisted in the ViewState.

Using javascript to open a popup window

I would like to open a popup window using javascript in my c#.net app. This is the code in the body tag in my webform
<script language=javascript>
function openWindow(strEmail)
{
window.open('CheckEmail.aspx?email=' + strEmail + , 'Check Email','left=100,top=100,toolbar=no,scrollbars=yes,width=680,height=350');
return false;
}
</script>
this is my code in the Page_Load section
this.btnCheck.Attributes.Add("onclick", "return openWindow(" + txtEmail.Text + ");");
right now I'm trying to pass the string from my textbox "txtEmail" so in my popup window i can get the request.querystring but Im a little unsure of how the syntax is.

No need of the last +
window.open('CheckEmail.aspx?email=' + strEmail,'Check Email','left=100,top=100,toolbar=no,scrollbars=yes,width=680,height=350');
and in CheckEmail.aspx page you can get the query string as
Request.QueryString["email"]
Use a ' in the CS side inside the function around the textEmail.Text
this.btnCheck.Attributes.Add("onclick", "return openWindow('" + txtEmail.Text + "');");

Why don't you get the email in the client code if the txtEmail control is visible.
function openWindow()
{
var email = document.getElementById('<%=txtEmail.ClientID%>').value;
window.open('CheckEmail.aspx?email=' + email + , 'Check Email','left=100,top=100,toolbar=no,scrollbars=yes,width=680,height=350');
return false;
}
