How To Refresh Combo Box In Vb 2005

Jun 16, 2009

I have some text boxes in my form that takes data and saves the data to the database. There is a combo box at the bottom of the page that loads data from a specific field of a database. when I enter and save the new data (using the textboxes), the combobox doesn't show the newly entered data. I tried to refresh the combobox using code like combobox.refresh, me.refresh etc, to refresh the form but nothing is working the combobox only display the new data when I close the form and reload the form again. anyway, the data loading in the combobox is done using datasource, displaymember, valuemember in the properties. So, how can I make the combobox show the just added record (field)?

Word 2007 Adding Adding Values To Combo List Box

Jun 7, 2011

I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?

Then the listview will updated with reference '10661'. After that click on another link, maybe leather sofas. The listview will re-update table with new reference '10662'

VS 2005 "refresh" The Sql Update Commands After Every Tableadapter.update?

Jun 15, 2012

Environment = VB.NET 2005 & Pervasive SQL 9.5 ADO.NET In a simplified example, I have single database table (customers) with the columns "customer_code_PK" and "customer_name" This table is presented in VB.NET 2005 as a single form datagrid (bindingsource/dataset). In this example, the database table is populated with the following data

customer_code_PK customer_name
SHELLShell Oil
BPBritish Petrolium
MOBMobile

In very simplified terms, code does the following;

sub on form load
fill dataset with database records (select * from customers)

[code]....

The datagridview loads the records correctly.Here is the sequence of operations that produces the bizzar behaviour.In the editable datagrid;

1.remove the row with PK = MOB -> save_button -> Database correctly updates

2.add a new row with PK = KFC -> save_button -> Database correctly updates

3.remove row with PK = SHELL -> save_button -> Database exception occurs

On this last command, the row SHELL is INSERTED!!, not removed.However, If I change ths save_button routine to this

save_button
call generate_custom_updateinsertdeletecommands
bindingsource endedit

[code]....

It works correctly !Is it correct that you would need to "refresh" the sql update commands after every tableadapter.update?

May 17, 2007

I have 2 drop down lists and 1 submit button. It works such that after the user has selected values from BOTH the drop down lists, then the user will click a "Search" button. My problem is, after the user click the "Search" button, the second drop down list is no longer displayed with the selected value, instead it displayed a default value. May I know how can I make sure the selected value remain selected even after the user clicks the "Search" button on the page?

Mar 10, 2012

I have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"

Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....

Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"

List Getting Cleared Every Button Click Inside Update Panel?

Apr 22, 2010

url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.

I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

If you have a form with two datagridviews that were dragged on to the form from a datasource that have a parent/child relationship with foreign key constraints. Is there any difference between using the binding navigator Delete button or adding a button to the form and in the Click event put "somebindingsource. RemoveCurrent". Basically what I'm trying to find out is if clicking the navigator Delete button causes "Removecurrent" or does it do something else or something additional.

Refresh A Databound Combo Box?

Nov 9, 2011

I have a program where a user can select something from a combo box in a data grid view control. I have it so that they can add something to the combo box via input box. The new item would automatically show up in the combo box at the bottom.

Now the problem is with deletion. I have it so that a user will click delete and a dialog box will pop up with the combo box. There a user will select an item and click delete. The item deletes just fine from the db but it doesn't update the combo box on either the delete dialog box or the datagridview. The only time it shows deleted is when I exit the program and reload.

Here is my load event that populates everything.

Dim cmTasks As New SqlClient.SqlCommand("Select * from Tasks where Department_ID =

C# - Refresh A Combo Box Item In-place?

Sep 17, 2009

The ComboBox Items collection is an ObjectCollection, so of course you can store anything you want in there, but that means you don't get a Text property like you would with, say, a ListViewItem. The ComboBox displays the items by calling ToString() on each item, or using reflection if the DisplayMember property is set.

My ComboBox is in DropDownList mode. I have a situation where I want to refresh the item text of a single item in the list when it gets selected by the user. The problem is that the ComboBox doesn't re-query for the text at any time besides when it loads up, and I can't figure out how else to do what I want besides removing and re-adding the selected item like so:

PlantComboBoxItem selectedItem = cboPlants.SelectedItem as PlantComboBoxItem;
// ...
cboPlants.BeginUpdate();
int selectedIndex = cboPlants.SelectedIndex;

[Code]....

This code works fine, except for the fact that my SelectedIndex event ends up getting fired twice (once on the original user event, and then again when I re-set the property in this code). In this case, it's not a big deal that the event is fired twice, but it's inefficient, and I hate that. I could rig up a flag so it exits the event the second time, but that's hacking.

DatagridView Containg Combo-boxes Can't Refresh

I have a datagridview bound to a bindingsource. This datagridview contains one column which is a combo-box.

Upon a click on a button,I change the underlying datasource. The selected values of the combo-boxes change.

But the change doesn't appear on the screen ! To make the changes visible (refresh each combo-box), I have to hover on the datagridview with the mouse or use the scrollbar !

Question 1 : why do I see this ?

Question 2 : what should I do to make the changes immediately visible ?
