In ListView, SubItems
- Thread starter patrick
- Start date
A Windows Forms
ListView and a Web Forms ListView are different controls. Code that works for one will not necessarily work for the other. If you're creating an ASP.NET Web Forms app then you need to learn how the ASP.NET Web Forms ListView control works, rather than basically just copying code written for the Windows Forms ListView.I using ASP.NET Web form.
I am converting From the code of the winform ListView To the code of the webform ListView.
I'm working on a code migration.
How do I convert ListViewItem SubItems to ASP.NET?
There aren't many examples of ListView in ASP.NET on the Internet.
There is no time to self-study on asp.net listview from the basics.

I know you are. That's why writing code for a WinForms control is useless. It's like you didn't even read the words I wrote. I didn't provide a link to the Web Forms
ListView control documentation for my health.Obviously not. There will be similarities but they are not the same. You need to learn how the Web Forms control works and then try to write appropriate code. If what you write doesn't work, we can help you fix it.
I don't know which function to migrate from asp.net to the functions ( SubItems, Color, Add, SelectedItems, SelectedItems[].SubItems[], Clone)
in the code below.
Please teach me the function ASP.NET that can replace ( [ In WinForm] SubItems, Color, Add, SelectedItems, SelectedItems[].SubItems[], Clone ).
C#:
ListView listAssign; // Declaration
// Initialization ListView
((ListView)listAssign).View = View.Details;
((ListView)listAssign).FullRowSelect = true;
((ListView)listAssign).GridLines = true;
ListViewItem item;
item = new ListViewItem("Apple"));
item.SubItems.Add("Banana"); //========= SubItems
item.SubItems.Add("Strawberry");
item.BackColor = Color.DarkOrange; //========= Color
listAssign.Items.Add(item); // ========== Add
// Function
private void btnDetach_Click(object sender, EventArgs e)
{
for(int i=0; i< listAssign.SelectedItems.Count; i++) // =============== SelectedItems
{
if(!listAssign.SelectedItems[i].SubItems[1].Text.Equals("Apple")) //============ SelectedItems[].SubItems[]
{
return;
}
}
ListView lvOriginal = new ListView();
foreach (ListViewItem item in listAssign.Items)
{
ListViewItem it = (ListViewItem)item.Clone(); //=================== Clone
lvOriginal.Items.Add(it); //================= Add
}
}The HTML source below is for reference.
C#:
<asp:ListView ID="listAssign" runat="server" Visible ="true">
<LayoutTemplate>
<table border="0px" cellpadding="1">
<tr style="background-color: #E5E5FE">
<th>firstname</th>
<th>lastname</th>
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label ID="txtFName" Text='<%#Eval("FName") %>' runat="server"></asp:Label></td>
<td>
<asp:Label ID="txtLName" Text='<%#Eval("FName") %>' runat="server"></asp:Label></td>
</tr>
</ItemTemplate>
</asp:ListView>

If you are doing this as a contract job, you shouldn't have accepted the contract, or built in time to learn.
If this is not a contract job, talk to your manager and tell them that you need time to learn, or need training.
Anyway, the link below should give you a crash course that is a little bit friendlier than the MSDN documentation. After going through the crash course below, I would recommend still taking time to read the documentation because there are other things worth learning in the documentation that is not in the link below.
ListView Control in ASP.NET
The ListView control displays columns and rows of data and allows sorting and paging. It is by far the most popular data display control, and is ideal for understanding how data display controls interact with data retrieval controls and code.

thank you for your teaching
I do not use data from DB.If you are doing this as a contract job, you shouldn't have accepted the contract, or built in time to learn.

The way you taught me is to DataBind() the DB.
I add each string data individually to the listview. So SubItem, Add concept is used.
I don't know SubItems, Add in Listview ASP.NET WebForm.
No matter how much I search on the internet, I can't find any ASP.NET Webform listview example data.
So use an
ObjectDataSource instead of a SqlDataSource. You're allowed to put your own thought into it rather than just copying whatever you see on the web.It seems like you haven't got the message yet so I'll just say it outright. We're not here to do your work for you. Sites like this are to get help with the stuff you can't work out for yourself, not stuff you can't be bothered to work out for yourself. If you're prepared to make an effort and run into an issue then we'll be happy to help. If you want us to write your code for you, you'll be disappointed.
