C# - Have A User Control With A Button Named Upload In It?
Feb 22, 2010
I have a user control with a button named upload in it. The button click event looks like this:
protected void btnUpload_Click(object sender, EventArgs e)
{
// Upload the files to the server
}
On the page where the user control is present, after the user clicks on the upload button I want to perform some operation right after the button click event code is executed in the user control. How do I tap into the click event after it has completed its work?

I have a file upload control on my page with a regular expression validator that handles the file format.
Users can upload files but I want the maximum WIDTH size to be 500px.
If any bigger I need to show a message advising the width is to great and stops them.

how can I know that the user already selected a file in the upload control, basically I need something like an event when the uploadfile control already have the filename, since I want to upload inmediately without having a second button that the user would need to click so the program can do the SavAs, I want to do it automatially after the user selected the file with the upload control.

My application allows a user to upload a file using the FileUpload control. The data contained in the uploaded file is then displayed to the user in a Grid for review if certain field validation criteria is met otherwise, a message is displayed stating that invalid data was encountered. If the data displayed is satisfactory, they have a 'Process Data' button to add the data to the system.
Initially, I used a simple If/Else block to determine if there was a file selected or not and if not, display a message to the user. As the coding got more complicated, this stopped working and I was told to use the RequiredFieldValidator control instead to get around the issues that arose.Now, I have a new issue: after the uploaded file data passes field criteria validation, the FileUpload box is cleared automatically and so when the user clicks the 'Process Data' button, the VC throws a message stating that the file name is missing from the FileUpload box.

I have a project where I'm rebuilding a legacy app and need to combine multiple similar web pages onto one ASP.Net web form. I thought I could easily do this with MultiView / View groupings. The problem I'm encountering is that each View control doesn't isolate controls of the same name.For example, I wanted to do this:
<asp:View ID="view1" runat="server">
<asp:Label ID="TEXT01" runat="server" />
</asp:View>

I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')

I have several regular expression validators in my site. Some validate postal codes, others validate phone numbers and still others email addresses or something else. What I would like to do is be able to specify a SkinID for regex validators that have a more specific purpose (e.g. postal code validation), but also have the default definition for regex validators apply as well.
So, I could specify some properties that apply to ALL regex validators and then some properties that are specific to certain regex validators (which I would specify by SkinID). Is this possible, or does only 1 .skin file definition apply?

I have a dynamically created page (read from database values) with grouped information. I wanted to add named anchors as each group is created. (Regular anchors will appear on the page also.)
I was hoping to find a jQuery plug or codeset example that could automatically generate and populate a drop down control for the page that provides the navigation to the named anchors.

I have a checkboxlist control and a button control in a popup forum. The button is diabled initially. I want to enable the button as soon as the user checks or unchecks any of the items for the first time in the checkboxlist.
<asp:CheckBoxList ID="CheckBox1" runat="server"></asp:CheckBoxList>
<asp:Button ID="SaveButton" runat="server" Test="Save" Enabled="false" OnClick="SaveButton_Click"/>
How to achieve this functionality ?

I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.

I have a problem with button event in web user control
First i have an aspx like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AddTest.aspx.cs" Inherits="AddTest" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="divContent" runat="server">
</div>
</form>
</body>
</html>
As you see i have a ScriptManager to do with ASP.NET AJAX, a div with ID divContent to load controls, then in code behind:
protected void Page_Load(object sender, EventArgs e)
{
divContent.Controls.Add(LoadControl("~/thitai/addtest.ascx"));
}
I add addtest.ascx to divContent as you see, and this is the code of addtest.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="addtest.ascx.cs" Inherits="thitai.addtest" %>
<asp:UpdatePanel ID="updatePanel" runat="server" ClientIDMode="Static">
<ContentTemplate>
<input type="button" value="Load text" onclick="updPanel('text');return false;" />
<input type="button" value="Load image" onclick="updPanel('image');return false;" />
<asp:HiddenField ID="hftype" runat="server" ClientIDMode="Static" />
<div>
<asp:PlaceHolder ID="plhControl" runat="server"></asp:PlaceHolder>
</div>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<script type="text/javascript">
function updPanel(type) {
$("#hftype").val(type);
__doPostBack("updatePanel", "");
}
</script>
Each time i click on Load text button, i change the value of hfType (hidden field) then do postback to server using UpdatePanel, then this is code behind
protected override void OnPreRender(EventArgs e)
{
string type = hftype.Value;
switch (type)
{
case "text":
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
case "image":
plhControl.Controls.Add(LoadControl("~/thitai/test/image.ascx"));
break;
default:
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
}
base.OnPreRender(e);
}
This is the code of text.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="text.ascx.cs" Inherits="thitai.test.text" %>
<%@ Register Assembly="Support" Namespace="Support.CustomEditor" TagPrefix="Editor" %>
<Editor:CustomEditor ID="edNoidung" runat="server" NoScript="True" Content=""
Height="500" ActiveMode="Design" NoUnicode="True" InitialCleanUp="False" />
<div>
<asp:Button ID="Button1" runat="server" Text="Show HTML"
onclick="Button1_Click" />
</div>
<div id="showHtml" runat="server"></div>
And code behind of text.ascx
protected void Button1_Click(object sender, EventArgs e)
{
showHtml.InnerHtml = edNoidung.Content;
}
The problem is: when i click to button1, the page do a postback using AJAX but event Button1_Click DOES NOT FIRE!
