I am having nearly 20-25 textboxes on the form. I had already given tab index to those textboxes. So when i press enter, the textbox tab index must be navigated instead of tab. After entering text in TextBox1, when i press enter, it must goes to the TextBox2.How to do this?

View 10 RepliesI have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.

View 3 Replies1. I type the first letter of the username i want in the combobox text area, the combobox drops down and shows me all the usernames starting with that letter. I scroll down to the name i want (as i scroll down, the text area holds each name but the SelectedIndexChanged event does not fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
2. I do the same as above, but instead of hitting Tab key, i hit the Enter key. The same thing happens and i get the result i want.
3. This time, i first click on the dropdown arrow of the combobox such that it shows all usernames starting from the first name. I then type the first letter of the name i want. I saw that another drop down appeared in front of the first one and it was a smaller subset of names starting with the typed letter. I scroll down this smaller dropdown to the name i want (here also, as i scroll down, the text area holds each name, and the SIC event doesnt fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
4. I do the same as #3, but this time i hit the Enter key instead of Tab key. But this time, the combobox text blanks out and the SIC event is not fired (although the name showed up just before i hit the Enter key). So i do not get any results back.
I keep getting the error message "Index out of range exception" when I run the following code.
XX
GN3 = (Loops * 5)
For a = 1 To Loops
For b = 1 To GN3
R1 = Seeds1(Counter1)
Randomize()
R2 = CInt(Int((56 * Rnd(R1)) + 1))
Counter1 += 1
MessageBox.Show(R1 & " " & Counter1 & " " & b & " " & GN3)
Next b
Next a
The message box conforms that the last entry in the array has been reached. And that Counter1 and b both start at 1 and go to 2845. And that GN3 is also 2845 all of the time.

View 3 RepliesHow I can find the index for the listview on a listview click event to something like this:
Private Sub listView1_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs)
MessageBox.Show(listView1.Items(e.Index).SubItems(1).Text)
End Sub
I don't want to use for each integer in the listview as i would keep getting the loops which I would hate to use it. I only want to use something like e.Index.
I know that the index is not a member in e, but I don't want to use listview item check event due to loops.
how I can find the index for the listview items without using for each integer as only using e.index?
