Databound ComboBox Need To Force Update In Datasource When Selection Changes

Apr 5, 2010

I have a combobox where the SelectedValue on the combo is bound to a property on a business object.Everything works fine, but the property that's bound to the SelectedValue on the combo only gets updated when the focus leaves the control. I understand that the property doesn't get updated until the control is validated (loses focus), but I need it to update the datasource as soon as the dropdown is closed.I know I could probably leave focus from the control on the DropDownClosed event but I'd prefer something a little less kludgy.What's the best way to immediately update my datasource when the dropdown is closed?

Combobox - When Select A Value From The Combobox The Selection Won't Validate?

Feb 22, 2012

I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

Populate Combobox From Selection Of Another Combobox?

Jan 1, 2012

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.

Dim proj_num, rng As Range
Dim data, i As Long, j As Long
With Sheet1

Feb 6, 2012

I have a vb application sitting on an sql server with 4 different tables. I want a scenario where when I select any table from the combobox, every query I will run should use that table as a reference.

E.g. ComboBox values(tables)=A,B,C,D

If A is selected then
SQLQuery="Select * from A "

If B is selected then
SQLQuery="Select * from B " etc

Databound Combobox Selection Retention

Apr 20, 2009

On my form I have three fields and a datagrid view.One field is a combo box.All fields are databound.The datagridview is a detail grid, bound in the "normal" way. Scrolling through records, etc., all work fine.What doesn't work is when a selection is made using the combo box.The underlying table has a self-join of one-to-many: ParentID, ChildID. ChildID is the main ID for the underlying table.Children may have a parent This is just by way of example.So, the combo box's Value is bound to ChildID, and the SelectedValue is bound to the ParentID.On the form one chooses the Parent with this combo box.When I test this arrangement, I select a Parent, then click Save (using the default toolbar actions). However, the combobox seems to "reset" the selection to the first in the list.

Outputting ComboBox User Selection?

Feb 3, 2009

I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:

At the moment I am using:

lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()

Saving New Selection From Combobox To SQL Database?

Jun 17, 2010

I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.

Here is the code for the Save button:
'Save changes to Locations db
Private Sub btnSaveClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

CellClick Event - Selection From ComboBox Not Smooth

May 28, 2012

I have a DataGridView with two columns. One is DataGridViewComboBoxColumn and other is DataGridViewButtonColumn. To capture the button click from the DataGridViewButtonColumn, i have written the CellClick event and it is working fine. However, this is not making my selection from the DataGridViewComboBoxColumn 'smooth'. What i mean is that i have to click on the combo-box twice for it to show the drop-down list. I have noticed that at every click, CellClick is fired. But only after the second click the drop-down pops out. What is the work-around for this?
