Hello,
I need to extend the ComboBox control so that while the user types text, it automatically displays its drop-down containing only those of its items that contain the text being typed by the user. This is almost similar to using AutoCompleteMode = Suggest and AutoCompleteSource = ListItems but It must show not only items that start with the text being typed but all that have it as substring. How can I achieve this?
Thanks
Silvia Terzi

Yes, it's good. But how much is this?

Hello,
You can visit our website www.componentone.com for details to
purchase the control.

It will be better if you use the Text_Changed Event of the combobox to fill out the details as items
by selecting from the database
In the database we can use some query for filtration as like '%datahere%'
before filling the data in the combo box we can clear all the previous items there.

Your seriously going to consider doing a database fetch on every keystroke in the control?? 
Think about the number of records you could possibly return, possible network speeds involved, how long to fetch and transfer those records, wipe out and repopulate the combo's list, yada, yada, yada, ... and you'll see how bad of a solution this is.

There is no event name "Text_Changed" under combo box of wpf.

Here we set the ComboBox Property
DropDownStyle=DropDownList
after setting the combobox property user only select a value from this list ,user can't write any in this combobox.
If user want to add more values in this list, user set the combobox property "Items", Here user can write our values

You might want to shorten up your name a bit. It's 3 lines long and wastes a bunch of screen real estate.

I'm developing a piece of software too (not web based). On monday I was doing some research into how to send email. First thing I thought was "I need to send email using visual basic .net". So I went to google and typed in strings such as (by 'no luck' i mean that the answer wasnt on the first page)
"send mail .net" - no luck (only comes up with asp.net solutions)
"send email visual basic" - no luck (only comes up with vb6 solutions)
"send email .net" - no luck (only comes up with asp.net solutions)
"send email .net msdn" - THE ANSWER
how hard was that?
I dont want to put you off posting questions, I've found a lot of answers here in the past, but in future use GOOGLE before you ask.
and if you're still stuck heres the page that gave me all my answers

Hi Friends,
I am using DateTimePicker in my page.
But I want that datetimepicker control should be enabled for only current month and when we select previous or next month it should be disabled.
Please help me for this.
Regards,
|
|
|
|
|
What you will need to do is to write some code within the selecteddate changed event.
you should check the datetiempicker selecteddate vs system date...do a month comparison and then set the dtp.enabled to true/false.
hope this helps
|
|

|

Try this code
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
If Not (DateTimePicker1.Value.Month = Now.Month AndAlso DateTimePicker1.Value.Year = Now.Year) Then
DateTimePicker1.Enabled = False
Else
DateTimePicker1.Enabled = True
End If
End Sub
|
|
|
|
|
For displaying current month in vb.net
we use Month(ToDay)
It display current month only 
|
|
|
|
|
If you're talking about the ASP.NET (Web Forms) version of the control, you can set the MinDate and MaxDate properties to limit the range the user can select from.

I have created database driven menu in which against each menu item some function name is stored. I want to call function each menu item in vb.net as this function is defined in VB.net.
Thanx

You might want to have a look in the Reflection namespace. Specifically the MethodInfo class.

You can create a database table storing something like:
menuname functionname
open openfunction
new newfunction
We can easily retrieved the function name from the database for the menu clicked.
After the function name is received by us, we have to use Reflection.
I am giving a code sample like this:
Sopposing I have a class where the functions are available
<b>Public Class Class1
Public Sub openfunction()
MsgBox("This is open function")
End Sub
End Class</b>
Then I have a button on the form, I want to call the function using reflection.
You have to import System.Reflection namespace
the code goes like this:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim t As Type = GetType(Class1)
Dim o As Object = Activator.CreateInstance(t)
Dim mi As MethodInfo = t.GetMethod("openfunction")
' U can write the variable which store the methor name in place of openfunction
mi.Invoke(o, Nothing)
End Sub
The code will slightly change when we will be using any reference assembly or resolving the assemblies at runtime.
Hope the solution is OK for you.

First create a function
like fun1()
use this funtion
[private\public\sub] fun1
............
....... .....
end sub
