How can I do on click event in order to load images using an Id.?
I've constructed a simple horizontal DataList that will contain 'N' number of items. I'm now trying to wire it up so that when the user clicks on any item a server-side event is fired. To accomplish this I'm following this article: [URL]
Here's the critical code I have so far:

i have datalist and on button click event i check the checkbox is checked or notfor this my code is
<asp:DataList runat="server" ID="dlstproductsize">
<ItemTemplate>
<input type="checkbox" value="<%#eval("size_id")%>" id="chksize" runat="server" /> Â Â <%#Eval("name")%>

I have a detailsview control, which I use to enter data and save to the database. I am using object datasource to connect to the db. The detailsview control has autogenerateinsert = "true". When the insert is successfull, I want to set some variables and and to redirect the page to a different one. I don't know how to access the insert button click event of the detailsview to do it. If there is different solution like using <insertItemTemplate> and using custom linkbuttons.

I'm trying to do something what I thought was simple: Attach a local click event to a DataList item. Yet I can't get it to work.
To make things simplest for everyone to understand I've created this sample little project.
I created a datalist which contains hyperlinks that when clicked will redraw the page and update my another datalist in the same page. How do I hide this datalist after click any of its hyperlinks?

How to change css when I click on some of the links in Datalist and active link to have some another css with background color blue?
We have a Datalist in which we have some data. Out of the 6 columns present in the datalist one of them is the primary key. Each row in the datalist has a "plus" button that will expand in the same window and display other data related to the primary key(in the same row)other than the 6 columns data that is displayed.
What I want to achieve is that on the button click, the primary key related to that particular row of Datalist should be fetched into a variable(whose button control is clicked). How to accomplish this? I am not able to find a solution as to when I click one of the buttons in a row, the particular primary key for that specific row should be attained so that I can call another function and hence retrieve the other data needed.
I am using datalist control on Default.aspx. In that datalist control I have ASP Link Button and the data is fetched from the Database while loading the control. Now, When my user clicks on that particular Link Button, the data associated with it should be shown on the next page. Which event shall I use? How do i select the values that I would show on the next page?

This is just one thing i want to do with my controls in my datalist, so i don't want to in my aspx file like this:
<asp:CheckBox ID="CheckBox1" runat="server" Visible='<%# if(Eval("isFolder")="1","false","true") %>' />
Because i have quite a lot of things i would like to do in the code behind when i'm getting my files..
Is it possible somehow to achieve this without having to put servercode in my aspx file?
I am writing a system that is input intensive, and the used need to be able to use without touching the mouse. I am trapping the enter key and defaulting to click an "Enter" button that I have on the screen. In the EnterButton_Click event, I am using a "menu option" to determine which DataList item they want.
All of that is working great, except reading back the URL from the DataList Item, which I need for my repsonse.redirect to call the next screen.

I am inches away from pulling this off.Entire code is below. The actual datatable/datasource will come from a file later, I just mocked up some links for this example.

I have a datalist control that is querying a accessdatasource for information that populates the results based on w/e is typed in a textbox. I can't figure out how to pass the information that is populated in the datalist to another page when a button is clicked (inside the datalist item template).
I was able to peform this in Detailsview with a hyperlink using the following arguments:
DataNavigateUrlFieldsDataNavigateUrlFormatStringBut this seems not to exist in Detailsview. Could someone point me in a direction on how to acomplish this?
I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?
