Programatically Select Item In DataGridViewComboBoxColumn?
Jan 11, 2012
I have one question, which is bugging me for a while.Let say, that i have a datagridview with one comboboxcolumn and few texboxcolumns.Comboboxcolumn has multiple values, etc, GR10, GR20, GR30, GR40, GR50...... (comboboxcolumn is bind to datasource).User has option to manualy select values in comboboxcolumn, but if they select some autocalculation in setting page of my program, i'd like to automaticaly select and show value in combobox.I searched tons of pages, but nothing useful.
How can i do that ? Is this even possible, becouse comboboxcolumn doesn't have selectedIndex property or something like that ?
I had a DataGridView, and already able to add DataGridViewComboBoxColumn to it. It read data from database StoredProcedure using custom ValueDescriptor class, this is the code for it:
Shared Sub fillComboBoxCellUsingSP(ByVal comboBox As DataGridViewComboBoxColumn, ByVal proc_name As String, ByVal param As Object(), ByVal firstitem As String) Dim dt As New DataTable
[Code]....
Actually, the line that read comboBox.Value = o is okay. But still, the combo box cell didn't display the value. Just empty. And sometimes, DataError event raised.
In my application I have a listbox and SelectionMode should be MultiSimple because users need to see which items they selected. In another tab we have another listbox this one should show all the selection users had done in first tab. Private Sub
I'm trying to programmatically select the first node loaded into a treeview.
There are 4 main branches - that each node is added to
'If ndeSelect Is Nothing Then ndeSelect = nde Select Case cdr(1).ToString Case "Translation"
[Code]....
I tried creating an NDESELECT object to "remember" the node - then tried the old boolean first/loop trick - but it's not remembering that SELECTEDNODE. Seems that the NDE object is just a node object - maybe not "smart" enough to know where it got loaded??
How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1 Const dcmPRICE_STRESS As Decimal = CDec(595.0) Const dcmPRICE_TIME_MANAGMENT As Decimal = 695
i have a treeview with 8 Root items, my program needs to add items to the treeview without me selecting the proper root or item, the root items have been coded so they cannot be deleted, but i'm not sure how to get the software to place data in a particular root by what its name is. when you add children the indexs change so im not sure where to begin. heres an example
how whould I go about deleteing an item from a listbox and it will select the next available item.you know like the treeview control selects the next node if you delete one.
Is it possible to always select the first item in a listbox?I prefer not to use listbox1.selectedindex = 0 or something like that because i have loads of listbox1.items.add etc. and that would just make the code bigger.so is there an option in a listbox or something..?
I have a listbox with items in it. And the top item is selected, how can I make it so when a button is clicked it goes to the next one in the list? I used this but UseClick(Listbox1.SelectedItem + 1) The selected item needs to be an string, and not an object.
what I want to do is make it so when i select the first item in Listbox1 it will also select the first item in listbox2 and if i select the second one it selects the second one on listbox2 as well. Is there a way to do this? i honestly have no clue and i know my code is wrong cus i do not know how to select the item # on listboxes but this is what i have:[code]

I have a combo box with a list of book conditions. When a book is loaded into the form, the condition the book has needs to be selected. How can I do this? Here's what i have: Excellent Very Good Good Fair Poor just for example, how would i select "Good" WITHOUT USING THE INDEX? The database knows the condition text, and condition id. I need to select the condition in the combo box with either. However, I don't know how to add the condition id to the items in the combo box. How would I do this in Visual Basic 2008? **EDIT** I forgot to mention, although i am using a database, i am NOT using SQL Server. I just need a way to select it with a variable containing either the id or condition.

I made my listview, and it's delete and edit events are working properly, now I want to implement a possibility for user to mark an element as "default". D, E and Def are buttons
so that would be a row from a table, I made delete and edit work by handling events from listview,
Private Sub lvMain_ItemDelete(ByVal sender As Object, ByVal e As ListViewDeleteEventArgs) Handles lvMain.ItemDeleting Dim refFac As new ReferenceFactory refFac.Delete(e.Keys(0)) EndSub
similar for Editing. But now when I try to get values from Default button, the button wont even do anything...This is the code:
Public Sub ibtDefault_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs ) SelectedRef.Name = "Test" End Sub
I just wanted to test it whether it will run or not by changing the value of my global string that will show which Reference is made default. But it wont even do that...Then I tried with Commands.
Private Sub lvMain_ItemCommand(ByVal sender As Object, ByVal e As ListViewCommandEventArgs) Handles lvMain.ItemCommand If e.CommandName = "Default" Then 'Dim refID As New Integer

I have a form (form5) with 1 combobox and 1 datagrid.The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname" The collumn "firm" will have some double firms with people in the other collumns ID Firm Fname Mname Lname1 AA John N West2 AA Jim L East3 BB Harry Sick Long4 CC Barry N Klote etc.I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles. I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i choose and doesn't filter. Is there anyone that can give me a clue on how to solve this.
