Declare event:-
public void ShowTextEvent MyEvent;
/////////////////////////////////////////////////////////////////////
void somemethod()
{
//////////////////////////////// Control is added
Controls.Add(NewControl);

Use XMLDocument to load your XML String or XML File and then iterate on it and when you reached the desired node use InnexText to set the new text.

Try using a WindowsService

I need to use it to show data for products or shops
As I’m making a e-commerce site
So, I want to know how I use the repeater in a dynamic way
To support the rows that was selected
And to target every column in a label and to put the title beside it
Thanks for help!

Wrong forum, it should be in the ASP.NET forum.
But:
in the aspx file:
<br />
...<br />
<asp:Repeater ID="MyRepeater" runat="server"><br />
<ItemTemplate><br />
<br />
<%# ((MyProductClass)DataItem.Container).ProductName %><br />
<br />
</ItemTemplate><br />
</asp:Repeater><br />
<br />
...<br />
in the .cs file
Page_Load()
{
...
List<MyProductClass> products = MyProductClass.GetProductListFromDatabaseOrSomething();
MyRepeater.DataSource = products;
MyRepeater.DataBind();
...
}
it's usual practice to put the above code within a if (!IsPostBack) {... } block so that it only gets loaded on the first page load rather than after every postback.
Hope that helps,

Sorry, the first block should read:
<br />
...<br />
<asp:Repeater ID="MyRepeater" runat="server"><br />
<ItemTemplate><br />
<br />
<%# ((MyProductClass)DataItem.Container).ProductName %><br />
<br />
</ItemTemplate><br />
</asp:Repeater><br />
<br />
...<br />

I put this in m code:
public class Row : System.Windows.Forms.ListViewItem<br />
{<br />
public int id;<br />
public int online;<br />
}
And have this code
ListViewItem item = new ListViewItem(new string[] {reader[NAME].ToString(), reader[GAME].ToString(), reader[BNAME].ToString(), reader[BOARD].ToString()});<br />
Row row = (Row)item; <-- ERROR OCCURS HERE<br />
row.id = Convert.ToInt32(reader[ID].ToString());<br />
row.on1ine = Convert.ToInt32(reader[ONLINE].ToString());<br />
MainForm.listView1.Items.Add(row);
But i get the above error, that it couldn't cast ListViewItem as Row. Ive done this before with TreeNode and it all worked fine, what wrong with this one?
Why did my row.online get replaced with row.removed, it doesn't do it outside the code brackets?

I'm now just storing row in item.Tag, and it works (of course) but i still want to know why this won't work, i just can't see it.
|
|
|
|
|
Because ListViewItem and Row are different classes and don't have
1. an is-a relationship
2. implicit conversion operators.
It obviously won't work with TreeNode also,as that class is not related in any way to the Row class that you wrote. You probably would have used the Tag property, just like you did now.
|
|
|
|

Actually i didn't use the tag.
Whith the tree node i had:
public class Cheat : Windows.Forms.TreeNode
{
public string code;
public string gameid;
lots of other public strings
}
My class inherited from the TreeNode.
So i had
Cheat oNode = new Cheat();
oNode.code = stuff
oNode.gameid = stuff
this.treeview1.nodes.Add(oNode);
and i could go:
foreach(Cheat oNode in treeview1.selectednodes)
and
TreeNode main = new TreeNode();
Cheat gNode = (Cheat) main;
or
Cheat gNode = new Cheat();
TreeNode main = (TreeNode)gNode;
Oh, and yes, when getting the nodes back from the list they still had all the values that where stored in my custom things by just going
Cheat check = (Cheat)this.treeView1.SelectedNode;
MessageBox.Show("The code in the node is... " + check.code);

That code works because your Cheat class inherited from the TreeNode, which is exactly what you were casting it to and from. A TreeNode has no relation to a Row
- Aaron

This works as you create a Cheat object, store its reference using a variable of its base class (TreeNode) and cast back later. Hereby the real object on the heap stays the same (Cheat object) all time long.
The Row example doesn't work as you create an object of the base class (ListViewItem) and afterwards try casting to a sub class. This simply can't be done as the object on the heap is now Row.

If possible could anyone please suggest how to do Forcolor change in disabled mode (Black color) for Drop downn or combo box.
I got color change fine but i am having problem in binding all the items.I cannot see items after color change ,i just see something like System.Data.Datarow in the place of items in combobox.
I am using Window forms with C# (ASP.NET 1.1 framework) ,visual studio 2003.
Thanks
OR
Suggest some other way to do the forecolor change in disable mode for combobox.
|
|
|
|
|
What do you mean by disabled mode? I don't quite get it.
|
|
|
|
|
Hi ,
Disabled mode means when we set Enable property to false.Than it does not allow use to handle the control.Disable means you cannot edit,or nothing you can do.
Is this clarify your doubt?
|
|
|
|
|
Yeah i thought that what you meant, but i can't seem to be able to change any colours when its disabled.
|
|
|
|
|
Hi again,
Yes you can change the forecolor.Just go through this example :
http://www.codeproject.com/cs/miscctrl/disabledcombodisplay.asp
But for me the forecolor is changing but it is giving problem in displaying all the items of the combobox.It just displays one and it gets repeated several times.Just check the code of the above example.
May be you can suggest some more ideas.
Thanks
