C# - HowTo Create Buttons In Code-Behind?
Feb 14, 2011
My Code works perfectly with normal Buttons. But i need to add some Code-Behind to those dynamically added Buttons. Thus i'd need ASP:Buttons instead of Standard-Buttons.
How do i do this?
At the moment my working Code looks like this (only the important parts):
AjaxControlToolkit.AccordionPane nrX = new AjaxControlToolkit.AccordionPane();
Button b = new Button();
b.OnClick += Eventhandler(my_function);
nrX.ContentContainer.Controls.Add(b);
Currently the Eventhandler is not called. When i look at the produced source in the Browser, there is noch onclick Event or anything like that which is (i think) the problem.
So how can i change my "Button b" to an "ASPButton" b? Adding an attribute "runat="server"" doesn't do the trick, as this code is (of course) executed after the page_load..Or am i getting something wrong?

I've received a website that uses sql server on the live environment. In the code at many places sql is created, say: However, locally on my dev machine, I use sql server express edition. It looks like select * from mytable doesn't work there, but instead I should use: How can I get my local site to work? Is there a setting I can change or am I missing something else?

is it possible to dynamically create radio button options that are dependent on a value within a database? For example 'b' is stored in a field so then 'a' will also be a radio button option, 'd' is stored in a database field so then the other radio button options will be 'a', 'b', 'c'....the radio button list will change depending on the value stored in the database field.

I am trying to create different search methods using radio buttons. This is a web app. using asp.net and vb.net
1)Radio Button 1 - search by Account Number - txtAccountNumber
2)Radio Button 2 - search by Customer Last and First Name - txtLastName, txtFirstName
3) Radio Button 3 - search by Customer ZipCode - txtZipcode
One search button - btnSearch
By default, the search button is aligned to the txtAccountNumber (next to txtAccountNumber)
If option 2 is selected, the search has to align to txtLastName, and other txtboxes are visibly disabled
If option 3 is selected, the search has to align to txtZipcode. and txtboxes are visibly disabled
I tried the followings, but it did not work.
Protected Sub rbSearchZipcode_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs) Handles rbSearchZipcode.CheckedChanged
txtAccountNumber.visible = false
txtLastName.visible = false
txtFirstName.visible = false
btnSearch.visible= true
txtZipcode.top = btnSearch.top
This worked for windows form, but not for web form.

I have asp.net page on which I have placeholder and a button. After the button is clicked I want several LinkButtons to appear on my placeholder, and I want specyfic handler to be connected to click_event of my LinkButtons. Here is the code:
protected void Button_Click(object sender, EventArgs e)
{
for(...)
{
LinkButton l = new LinkButton();
l.ID = "link" + i;
l.Command += new CommandEventHandler(link_Command);
PlaceHolder1.Controls.Add(l);
}
}
void link_Command(object sender, CommandEventArgs e)
{
PlaceHolder1.Controls.Clear();
Label l = new Label();
l.Text = e.CommandArgument.ToString();
PlaceHolder1.Controls.Add(l);
}
The LinkButtons will be visible but their event won't fire. How should I solve this? I need to generate LinkButtons inside the Button_Click event, because only then I will know how many buttons to create.

I have a modalPopupExtender in my aspx web page pointing to a Panel and in Code-Behind I create buttons which I want them to show the modalPopup, so I have:
buttonX.OnClientClick = "javascript:$get(" + modalPopup.ClientID + ").show();";
but instead it just does a PostBack, even if I put "return false;" at the end of the past code.

I'd like for where there is a 1 for it to display a checked radio button, and where there is a 0 for it to be unchecked. This can then be edited by clicking the radio in another column where necessary.

I'm trying to create a list of image buttons dynamically, but I'm having trouble displaying the images. I'm using the Directory.GetFullPath method, but I don't think its the right thing to do.I've viewed the page, and the image path is showing as
'd:Hosting6238630htmlPropertiesCedarsext%20front.jpg'. I know this isn'r right and that it needs to be something like www.annereevelettings.co.uk/property/images..., but the question is, how do I do it?The page can be seen at the following address

Is is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.

How are C# and ASP.NET related? Is it true that I don't have full control over the output, unlike in PHP and Python?How easy is it to create code that is compatible with .NET 2.0, 3.5 and 4.0?
Added questions:I've heard ASP.NET pages are compiled. Is that why it makes no difference whether I use C# or VB.NET? I only need something that can compile targetting the .NET platform? Can I intermingle VB.NET and C# in my pages?
