I have a ComboBox. I want it to allow select only listed Items. How can I have it display an initial legend?
[Code]...
With this code the ComboBox displays with no text. If I remove the ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList sentence then the text in ComboBox1.SelectedText = "Select Item"is displayed, but the user can input other values in the combobox that not match the listItems.

i have an app that has many suggest append comboboxes in the style of just straight dropdown.
I also clear the text in all of these draopdowns via resettext() in a loop when my user clicks a 'New' button
is there any way to either A:
make the combobox read only (without selecting dropdownlist)
or B:
allow suggest append to fire on all keystrokes instead of only when it sees a match in the combobox....
example: combobox1 contains the following items:
- apples
- oranges
- bananas
as of right now, if my user types in "pears" it won't see any 'P' and won't suggest anything else or even drop down the combobox and allow "Pears" to be entered and because my app does processing only on the items in the list, "pears" then throws an exception....I'm trying to force them to choose only the items in the list and not be allowed to enter anything else while still enjoying the clean look of a resettext() on a combobox

I have a combo box on my application (working with VB.net) called CmbAttendantstatus. I have sent the dropdownstyle = dropdownlist at the Properties level of the combobox.
There are 200 field types e.g;
Current Attendant
Ever Attendant
Never Attendant etc
The issue is I can only select one from the list, fine, but I want to be able to type the first letter on the combobox and it takes me to the nearest field type rather than looking through the entire drop list. For example I want Never Attendant, I just need to type N and the drop list takes me to anything starting from N and if I add E for example any field starting with NE shows up for selection. Presently, when the dropdownlist is selected you are not allowed to type anything...
Im using Visual Studio 2008 (ASP.net) to build some web pages..
I have a DropDownList linked to a DataSource from data base to fill it automaticly, and it works perfect, but I want to modify the items before its displayed ?
I am using VB.Net 2010, and when I run the following code, I get System.Data.DataViewManagerListItemTypeDescriptor displaying in the dropdownlist box
cmbProdType.DataSource = ds
cmbProdType.DisplayMember = "ProductType"
cmbProdType.ValueMember = "ProductCode"
When I hover over the datasource, I can see the correct records. But its not displaying in the dropdownlist control.
I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")
[CODE]...
When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.
How to query a record in vb.net using combo or textbox via linq to sql like the search engine? Just like when you search in google or youtube, once you typed in the initial string on the textbox or combo box it will show a drop-down list. I tried to use it in my application using linq method but the problem is it would duplicate on the first string that you entered on the dropdownlist if that record exist on your database after you press the space key. I used the code below which duplicates the records on the drop-down list when you type in your string after the space key.
I just want it to be like in any search engine that when you type in the string or your initial string, it will display on the drop-down list all the records from the database that contains the string you entered without duplication. In my case, I'm trying to query a name from my database. This is how it should work, For example, if you type an initial string in the textbox or combo box a named 'Mark', it should display all the names from the database containing 'Mark' into the drop-down list before it changes into its final string that you entered.
Here is the codes I used:
Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles
ComboBox1.TextChanged
Dim db As New MultipleDatabaseOperationDataContext
Dim search As String
search = ComboBox1.Text

View 5 RepliesI have a drop-down ComboBox, where the values are a range of indexes, followed by a key value. So one line looks like:01 : 01010101010101010202020202020202
I have set the ComboBox up so that on the form, only "01 :" is displayed, but the DropDownWidth allows the entire string to be seen when the dropdown arrow is clicked.However, once that is done, I am left with "0202" (the last four characters) showing in the ComboBox, rather than "01 :" until the control loses focus. How can I force "01 :" to display?
