I have multiple items in a checklistbox. In the page load, I'm trying to check specific items in the list (2,4,8)
I've tried cbl1.items.Item(2).checked, and different combinations of this and I can't get anything to work.

I have a CheckListBoxthat is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a CheckListBoxthat before so I'm not really sure how to go about this. Here is what I have tried so far:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
Dim TempNameList As New ArrayList
If cmbRemove.SelectedIndex = 0 Then
TempNameList.AddRange(NameList)
Array.Clear(NameList, 0, NameList.Length)
When I re-display the array into the CheckListBoxthat it shows that nothing was removed from the array.
I've searched the forums and have only found similar things for ASP but not this exact function in VB.

When one is clicked, would like to be able to have it checked, and uncheck all the restCheckOnClick will not uncheck the rest (I want an effect similar to radio buttons).My first plan was to loop through each item in the ToolStrip Items() array, however these are ToolStripItems (which are a base class) and thus do not have the Checked property. So then I thought about using CType to convert them to ToolStripButtons, which do have the Checked property, except what should I do about the ToolStripSplitButtons?I basically want to say, "if this ToolStripItem is as ToolStripButton, then uncheck it"

View 4 RepliesI have a grid of RadioButtons, and need some help in Check / Uncheck acording to data collected from a .txt file.
The .txt file contains a list like this:
A01,a
B01,b
C01,c
A02,a
B02,b
C02,c
I have set up in a grid formation RadioButtons, and named them A01,B01,C01,A02,B02,C02. I have loaded the .txt file in an array, and want to use the first 3 letters in the array to point to the RadioButton.
Problem: How do I get the string "A01" from the array to point to the RadioButton control?
I use a SqlDataAdapter to fill a DataTable and then set that DataTable as the DataSource for a DataGridView. All works well. Then I add a column at the beginning of the DataGridView that will allow a user to check/uncheck a row for further processing. All works well. Then I display this to the user. All works well.
Since there are many times when the DataGridView could be displaying hundreds or maybe thousands of records, I have a button that will "Check All" records and another that will "Clear All" records. These work fine, but I've noticed a serious performance lag. Other test code that I've got shows that in an unbound DataGridView, even a large one with 50+ columns and 5000 rows, checking or unchecking all of these fields takes mere fractions of a second. (One test with 50 columns and 50,000 rows still only takes 0.334 seconds to check all of the rows.)
In my testing (with my current code), checking/unchecking 500 rows takes 15 seconds. Is this because the DataGridView is databound? If so, is there a way to UNbind it (making it simply a stand-alone set of data)? I don't need to push updates back to the server, so there's no danger in removing any databinding. I've even toyed around with this (to make the DGV unbound):
