Code:
<telerik:RadAsyncUpload ID="FileUpload1" runat="server" Skin="Forest" Width="272px">
</telerik:RadAsyncUpload>
And I have a asp.net button defined like this
Code:
<asp:Button ID="btnUpload" Width="180px" Height="30px" runat="server" Text="Upload"
onclick="btnUpload_Click" />
Now it works and it uploads the file , but now i want to have a Progress Bar , so like other controls i did the following
Code:
<telerik:AjaxSetting AjaxControlID="btnUpload">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="btnUpload" LoadingPanelID="RadAjaxLoadingPanel1"></telerik:AjaxUpdatedControl>
[Code] ....
If I add this Ajax code , my Upload does not work , it give me the Following Error
Code:

C# - Windows.event Is Undefined -Javascript Error In Firefox
Jan 22, 2010I'm using javascript to change some settings of asp button on mouseover. It is working in IE. But not working in Firefox. Is there any other javascript code that will support almost all browsers? My code is as follows
<script type="text/javascript">
var previousColor;
function Changecolor() {
previousColor = window.event.srcElement.style.backgroundColor;
window.event.srcElement.style.backgroundColor = "Blue";
window.event.srcElement.style.cursor = "hand";
}
function RestoreColor() {
window.event.srcElement.style.backgroundColor = previousColor;
}
</script>
<asp:Button ID="btnSearch" runat="server" BackColor="#800000" Font-Bold="True" Font-Names="Arial" onmouseover="Changecolor();" onmouseout="RestoreColor();" ForeColor="White" Height="28px" OnClick="btnSearch_Click2" Text="Search Jobz" Width="117px" />
C# - Javascript Undefined Attribute - Why Source.full Is Always Undefined On The First Click
Nov 22, 2010I have a GridView with the following event:
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
foreach (TableCell c in e.Row.Cells)
{
c.Attributes.Add("full","false");
}
}
And in my javascript I have an onClick event for every cell:
if(source.full="false")
{
...
source.full="true";
}
else
{
...
source.full="false";
}
Why is it that source.full is always undefined on the first click?

View 2 RepliesC# - Is There Equivalent Of WPF OriginalSource Event Property In Winform?
Jan 23, 2011From:
[URL]
The OriginalSource property of the object identifies the original object that received/initiated the event. Consider a custom control (called CustomControl1 in this example) that is composed of a TextBlock. When a MouseDown event is raised on the TextBlock, the OriginalSource property will be the TextBlock, but in CustomControl1's handler, the Source will be changed to the CustomControl1 object so that other elements along the event's route will know that CustomControl1 received a MouseDown.
Is there equivalent of WPF OriginalSource event property in Winform and ASP.NET ? If not how to emulate this ?
C# - Adding Delegate Or Event Property To Class?
Oct 4, 2010I created a control where other developers can create an instance and use. There is a button click in the control. How do I allow developers to plug in their own code in a certain part of my control? I am not sure if or how exactly to use a delegate or event in this scenario.

Web Forms :: CheckedChanged Event Not Firing When Checked Property Set On Page_Load
Jul 21, 2010I have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.
Get Total Row Count And Why Is The GridView's DataSource Property Null In The DataBound Event Handler
Jul 22, 2010I wanted to get the total row count in a GridView's databound event handler, so I tried the following:
protected void grid_DataBound(object sender, EventArgs e)
{
GridView grid = (GridView)sender;
DataSet data = grid.DataSource as DataSet;
if (data == null)
return;
int totalRows = data.Tables[0].Rows.Count;
}
The problem is that the grid.DataSource property is null. The DataSourceID property is not null, so does that mean that I can't access the DataSource object in the DataBound event handler unless I assign the DataSource property directly?
Edit1: Here is the code in my GridHelper class for adding rowcount to the BottomPagerRow. I would like to get rid of the requirement to pass in the ObjectDataSource, but can't because I need to use the Selected event to get total row count. Hence the reason for the question. I also think this might be better in a custom control where I can access ViewState, and/or create child controls during the Init event (I still have a problem to resolve with the way the pager renders with an extra cell), but then I'd still have the problem of how to get to the total row count when the DataSource itself doesn't appear to be available in any GridView events.
Edit 2: Not really relevant to the specific problem, but I resolved the problem I was having with the pager rendering so i've updated the code posted. I found the trick here: [URL]

Resolve Code Blocks At Runtime (C#)?

myLink.Text = "The link";
myControl.Controls.Add(myLink);
I want to be able to resolve the myLink.NavigateUrl at run-time according to the context that myControl puts the control into in the end (this is not a WebControl and therefore adding to the collection of controls doesn't output to page).

Can Use HTML Base Tag To Resolve A Virtual Directory
Jun 16, 2010I have an ASP.NET MVC web application running in IIS as a subweb; let's say its path is something like http://mysite.com/subweb.
I have a view which serves content obtained from a CMS. The CMS editor has entered some content containing a relative image path <img src="/images/imga.png" />.
This works fine on the production server where the site is the root website, but not on the staging server where the site is a virtual directory under the root website
The path should be <img src="/images/imga.png" /> on the production server
and <img src="/subweb/images/imga.png" /> on the staging server.
Is it possible to use the <base> tag to resolve this image path?
<head>
<base href="http://mysite.com/subweb/" />
</head>
<html>
<body>
<img src="/images/imga.png" />
</body>
</html>
It doesn't seem to work. Can anyone explain why or if this is a workable approach? I don't want to require the content editor to have knowledge of the website deployment option (which changes between UAT and production).

View 4 RepliesC# - Error - Cannot Resolve Symbol 'symbolname' In ReSharper
Apr 4, 2011Using VS2008 and R# 5 I'm running into an odd situation, where on an aspx page I keep getting
Cannot resolve symbol 'symbolname'
But the code compiles and runs fine. While having a fix for this would be great, I'm just trying to figure out if I'm losing my mind.
The CodeFile directive and Inherits directives are fine. If I compile the app or just let devenv sit for a bit it'll go away, but as soon as I save the aspx [via ctrl+s] R# suddenly has trouble with the Inherits attribute and flips out on every method in the page (OnClick etc).
// Anonymized of course but otherwise intact
<%@ Page AutoEventWireup="true" CodeFile="TestPage.aspx.cs" Inherits="TestPage" Language="C#" MasterPageFile="~/MasterPage.master" Title="Test Page Title" %>
This is mostly just a grievance, because since the code compiles it doesn't stop me from doing what I need.
I would post a bug report to the JetBrains site but first I would like to know I'm not alone. It could be my machine. Maybe when I roll to VS2010 in a couple weeks this will go away?
