For some reason my RadComboBox "EmptyMessage" is not showing on the initial load of the page but it does after I focus and blur out of the control. How can I force my "EmptyMessage" to show by default?
My .aspx is as follows:
<telerik:RadComboBox
ID="SomeFilter" runat="server"
EmptyMessage="Choose..."
OnClientSelectedIndexChanging="OnClientSelectedIndexChanging"
[Code].....
My combobox defaults to "Test1" by default instead of "Choose...". Once I open and close the combobox, however, the default changes to "Choose...".

I found this really cool page that allows you to hook up facebook into your site: See here
<iframe id="MyIframe" src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fwww.EXAMPLE.com%2F&layout=button_count&show_faces=true&width=100&action=recommend&colorscheme=light&height=21" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:100px; height:21px;" allowTransparency="true"></iframe>
I want to be able to call this iframe in my page (I am using ASP.NET) and I want to be able to set the visibilty based on a variable and most important I want to be able to change the src of the iframe based on a string that is build up by variables to change the [URL] to another URL based on the location of the page.

I was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

I have been reading up on a few atricles, and am now vey confused on which is the best option and how to go about it.
I have an aspx page that has a gridview with x amount of records. Each record has a checkbox to selet that record for processing. When a user clicks a button it runs some vb.code behind which generates a file for all the records selected in the gridview. This works fine, however, I also want to display a report at the end.I created a rdlc report ("ItemListing") which I can display in a reportviewer. What I want to do is show this report as a popup / new window infront of he current aspx page , to allow the user to print or save . I also want the user to be able t close this window.

I have an application that initially display 4 grid views at page load. This process takes 50-60 seconds and I would like to change the process to display the web page, show message like "Data being loaded, please wait..." and then spin off a thread that fills the various grid view. When this is done I would programatically like to do a post back to show the result. Not sure if this is possible? I tried something like this:

I'm having a hard time with the page cycles when using masterpages and contentpages. My masterpage has two linkbuttons that are used to select a language (using resources). When these buttons are clicked I create Session["language"]. The goal I have is to 'translate' my masterpage after the buttons are clicked AND to translate the content page.I've been trying all kinds of different methods (Page_Load etc) based on this url: http://msdn.microsoft.com/en-us/library/dct97kc3.aspx but it never works like it should. Usually the content page only gets translated after two clicks. I can't figure out the cycle problem between the masterpage and the content page combined with the click-events.

What I have is button that should open another page only if textbox length is 8. Javascript must be added from code because it does not simply calls the bla.aspx, it's more like bla.aspx?id=4&code=234 etc etc...
I have this code on server side
button.Attributes.Add("onclick","javascript:window.open(bla.aspx)");
on client side i have
<asp:TextBox ID="policyNumberTxt" runat="server" MaxLength="8" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="policyNumberTxtRev" runat="server"
ControlToValidate="policyNumberTxt" ErrorMessage="Length must be 8."
ValidationExpression="{.{8}.}" ValidationGroup="bla" Display="Dynamic"></asp:RegularExpressionValidator>
<asp:Button ID="printBtn" CssClass="button" Text="Print" runat="server" CausesValidation="true" ValidationGroup="bla" />
What happens is that when I click the button page bla.aspx opens, and even postback is trigered. Validator is showing the message, but page is opened and postback trigered.
How to handle this? Validation is broken...

I have some static (pure html) pages in my MVC application that I need to authenticate, so that not just anybody can look at them. Is there an way to do this without moving all the code to asp files and adding a controller and from there use the Authorize attribute? I would really prefer to not need to do this!

I'm writing a simple web site using codebehind for each page, however using the "codefile" directive, not "codebehind" as such, because I'm not precompiling. I'm just using a text editor to edit the aspx and codebehind files. Problem is, every time I make a change to the code or the aspx file, and refresh the page in the browser, it takes a 2 or 3 seconds to come up the first time, like it's doing an on-demand initial compile. I assume that's what it's doing, as after the initial load, the page refreshes without any delay at all.
This behaviour is quite frustrating when making small changes to the html or code. I'm coming from classic ASP, where you could edit-refresh-edit-refresh etc. all day without your "stride" being broken by waiting for a "compile", you know? So I'd love to know if there's a setting which prevents this initial delay. When I want to deploy, I can do a compile or something, but while making lots of small edits, I just need the page to run without that initial delay.

I posted a similar question previously, but none of the answers worked and I've been scouring all over the web trying to find a solution. My situation, I have a Edit Window webform with a dropdownlist (Note: to avoid confusion, I'm using Telerik extensions only to decorate the webform):
<%@ Page Language="VB" CodeFile="EditFormVB.aspx.vb" Inherits="EditFormVB" %>
<%@ Register Namespace="CustomBoundField" TagPrefix="custom" %>

}

if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz as well)
return oWindow;
}

And in the code behind, I'm setting the datasource for the dropdownlist and using a function to query the DB for the name of the value I want to set as the selected value when the page loads initially: Partial Class EditFormVB Inherits System.Web.UI.Page
Public Shared category_Name As String = ""
Dim ddlDataSource As New SqlDataSource
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
DetailsView1.DefaultMode = DetailsViewMode.Edit
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Page.Title = "Editing record"
''Setup DropDownList SqlDataSource
ddlDataSource.ID = "ReqCategoryData"
Page.Controls.Add(ddlDataSource)
ddlDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("TTPRODReportsQuery").ConnectionString
ddlDataSource.SelectCommand = "SELECT TS_NAME AS ReqCategory FROM dbo.TS_SELECTIONS WHERE (TS_FLDID = 5299 AND TS_STATUS = 0) ORDER BY TS_NAME"
Dim args As New DataSourceSelectArguments
ddlDataSource.Select(args)
''Set max length of Title field to 70 characters
Dim dvrTest As DetailsViewRowCollection = DetailsView1.Rows
Dim TitleTB As TextBox = dvrTest.Item(0).Cells(1).Controls(0)
TitleTB.Attributes.Add("onkeydown", "isMaxLen(this)")
TitleTB.Attributes.Add("maxlength", "70")
Dim myDDL As DropDownList = DetailsView1.FindControl("reqCategoryDropDown")
''Perform dropdown list population operations
If Page.IsPostBack = False Then
Dim ticket_ID As String = getDataKey(DetailsView1)
''Fetch Category ID
Dim sqlText As String = "SELECT TS_REQCATEGORY FROM USR_ITFAC WHERE (TS_ID = " + ticket_ID + ") "
Dim reqDataReader As SqlDataReader = GetDataReader(sqlText)
reqDataReader.Read()
Dim category_ID As String = reqDataReader(0)
''Fetch Category name using the categoryID and set as selected value in dropdown list
sqlText = "SELECT TS_NAME FROM TS_SELECTIONS WHERE (TS_ID = " + category_ID + ") "
reqDataReader = GetDataReader(sqlText)
reqDataReader.Read()
category_Name = reqDataReader(0)
myDDL.DataBind()
myDDL.Selectedvalue = category_Name //<--this value gets set only when debugging,
End If
End Sub
Private Function GetDataReader(ByVal sqlText As String) As SqlDataReader
Dim dr As SqlDataReader
Dim sqlConn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("TTPRODReportsQuery").ConnectionString)
sqlConn.Open()
Dim sqlCmd As SqlCommand = New SqlCommand(sqlText, sqlConn)
dr = sqlCmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)
Return dr
End Function
End Class
The dropdownlist does get populated appropriately, however when I attempt to set the value, it doesn't reflect when the page loads; the dropdownlist just gets populated and no value is set to selected in the markup, so the first value is shown by default. The odd thing is that when I'm debugging, the value appears to get set when I step through the function, it's as if the selectedvalue is getting reset as soon as the function exits and proceeds to load the page.
SOLUTION: Had to add a separate function that is called onLoad from the DropDownList after the after Page_Load is done executing. Still unresolved is why the the DropDownList rebinds after the Page_Load.
IN HTML:
<asp:DropDownList DataSourceID="ReqCategoryData" DataTextField="ReqCategory" DataValueField="ReqCategory"
ID="reqCategoryDropDown" runat="server" AutoPostBack="true" OnLoad="DDL_DataBound">
IN CODE-BEHIND
Public Shared category_Name As String = ""
