Okay, maybe it's a bit pedantic, but do ASP.NET user controls HAVE to have an ascx extension?
My reason for wanting to know this is purely academic. I made the statement to someone that they usually have an ascx extension, but then I had the curious thought of if that was always true or not.
I have a page called main.apsx and on that page I have a multiview with a couple of view panes. In main.aspx I also have an have a buttons.ascx file with a few link buttons. When these buttons are clicked I want them to show the the selected view panels in multiview in main.aspx.
I cant seem to figure out where to put the action code for the link buttons. Do I put it into my buttons.ascx.cs file or into main.aspx.cs? I presume in buttons.ascx.cs, but if I do that, how will the buttons find the multiview control?
This is the code for on of my buttons in buttons.ascx.cs

When I run it like this is gives an error
The name 'MultiView1' does not exist in the current
The name 'View1' does not exist in the current
Here's the source of a blank .acsx file I created called LogOnBox.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="LogOnBox.ascx.cs" Inherits="ECommerce.Views.Shared.LogOnBox" %>
I want to drag some labels, and textboxes etc and give them style using a CSS file. How can I associate a CSS to an acsx file?
I am currently displaying the date via the Eval method in an ASCX file:
Code:
<%#Eval("BirthDate") %>
However this appears as mm/dd/yyyy when I would like it to appear as dd/mm/yyyy. Is there a global setting where I can change the default date format or is there another way to change it directly in the user control ASCX file?
I'm using vs2010, asp.net 4 webform.Is there anyway which i can update a code behind file (ascx.cs) file without compile the whole site.because i just want to debug some ascx.cs file, and compile a big whole site will cost 1 minutes at least.
View 1 RepliesI have a form in aASP User Control (.ascx) file. Maxlength does not work for the multiline textboxe hence it is generated as a textarea, which has no support for this attribute. I could maybe use some asp validation, to prevent submission of too much text, but I want to prevent it to be possible to even enter too many characters, just like is possible for single line textboxes... I don't know if the control has any onload event that I could use to add attributes to the textbox from code behind and and combined with javascript fix this or anything..
View 1 RepliesI have an aspx page with multiple modal popups. These modal popups are trigger in the page behind code using .Show() and .Hide().
This is what I have in the .aspx page for the particular modal popup under discussion:
[Code]....
The example below demonstrates the type of calls I am making to the modal popup extenders. Basically using the Datalist item command, the datalist commands are responsible for triggering my modal popups.
[Code]....
They all work fine after postbacks except the "activityReport" case (the last one). The only difference with this modal popup is that it contains a user control and all the postbacks are happening in the user control. So the problem is that in the last case whenever a postback happens in the user control then the modal popup is close.
1. If I separate the modal popup and place it in a page all by itself and trigger it to .Show() through a button click in the page behind code then the modal popup doesn't close. See below example.

2. The button click event in the test page looks as follow:

I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I wrote a one aspx page that include 4 ascx pages.
Among of them, two ascx pages are have to share a integer value.
A page can count a value, and I want it to be a part of other ascx page.
These pages have no button of link and neither user events.
I have a user control where is a textbox and button with PostBackUrl="two.aspx". This user control I have on a page one.aspx. When I click that button, on two.aspx I want to have access to the textbox from ascx control. PreviousPage.FindControl doesn't work. How to do that?
View 3 RepliesI have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
There is part of my code in .ascx:
public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");
}
I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.
how to get asp.net user controls(ascx) fields in normal asp.net page (aspx)
View 5 RepliesI'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.

View 3 Repliesi have mapped *.xyz extension to my own custom handler in asp.net and can run it on Windows asp.net.
How can I do the same thing on mono (Linux/Apache - ubuntu)?
I have this in my web.config:
<httpHandlers><add path="*.xyz" verb="*" type="MyCustomHandler,...">...
I also added similar things to mod_mono.conf and several other files but still I get http 404 The resource cannot be found.
I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension.
I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension.
First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests?
Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way?
