Forms :: Multi Column Combobox (looking For Method)?
May 14, 2010
I'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).
So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.
Regarding multi column search, i want to clear you the situation where one column contains say FirstName and the another column contains LastName for the 'Contacts Combo box', then when user types either FirstName or LastName for the person, combo box should search for the appropriate value into both columns.
for my fifth question consider the same combo box with FirstName, LastName all typed together shows in one column only then, by default combo box searches only for strings that 'Start' with the string typed in the textbox portion, insted of which i need a feature which allows me to let set the behavior of combo box search system tobe able to search for the typed strings within any part of record.i.e. If user types 'Ja' in textbox portion, the the list should show following maches

coding multi column combobox in a DataGridView cell. When I click the combobox cell from datagridview, It shows the multiple column such as Name, address and telephone. When I choose the item, it will return the value.
I could hard-code in the column names ("WO_Number",WO_CustID","CustLastName", etc...), but would prefer to pick this up dynamically (partly because I want to reuse this code later).
I have developed an application using vb.net. This application will run on approximately 15 machines at the main office and also roughly 10 machines spread over 3 different locations. I am using SQL Server Express edition in the backend. I deployed the application on the network using caspol but it is extremely slow. The Company Manager's perception is that because a script will invariably have to be deployed on each client machine to configure CASPOL, that the solution is not viable.
What is the best method to develop and deploy a multi-user desktop application?
First, I don't fully understand why VBA can have a multi column combobox but full VB doesn't? What purpose does it serve to only have a drop down list of text strings? I know there is an index property, but what if the items in the drop down can't logically be associated with an index value?
Anyways, here is my problem. I have an enumeration value that I want to add to a combobox. I have the code to go through and add the text of each enumeration value to a combobox. This is fine for enumerations whose values progress in order from 0-whatever. However, I have some enumerations whose values are, for example[code]...
Is possible to have different values of combobox on the multi same form?
Actually I want to make a multi same form, but with one combobox to set the authority. When different persons to use this same form, I will have different selection limited on this combobox,
I need to add data into a multi-column list, manually, in codes. I am using VB Express 2008. Could someone please hint me on how to do this with the following controls:
The ListBox or the ListView The Grid (I think it is the DataGridView)
Or anyother simple way of doing the stuff. All I want is simplicity.
I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.
The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.
(I have attached a relevant portion of the event sub where a user is adding new rows.)
Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click '... Dim ListBoxItemName As New TextBlock
[Code]....
I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.
My questions are:
1) How can I loop through the second column of percentages to show the running total and remainder?
2) Is there something more suitable than a ListBox that could make this easier?
I've been able to add my own non-bound columns to a DATAGRIDVIEW - such as a check box column.But I'm not seeing how to take a bound column and make that column be a combobox. Doesn't appear to allow that.Do I have to hide the real column and add a "fake" front-end column that I make a combobox?
just wondering if it is possible to add a method to all forms in my project without having to do it on one form and Inherit all my other forms from that one
In VB.Net 2010, is there any way to do multi-select in a drop-down/combobox, preferably with check boxes in the drop down? I've seen various discussions on the 'net about this but no such beast appears to exist within the tool.?
I've been searching and searching, but I haven't been able to find a halfway-decent way of adding multiple columns of data into a WPF VB.NET ListView. The data I'm adding is not from a datasource. [code]...
Means if i have two columns in database namely name & email i wanna search the users or email by entering either name or email on textbox then after clicking the search button record will be displayed in gridview ?can anybody tell me the select query for this ?
I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.
I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.
I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.
When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]
