Forms :: DatagridView ComboBox ?
Dec 13, 2009
Here's my scenario...I have 2 datagridviews in my Windows Application.When I click on a row in the parentgrid, a child grid shows up with data regarding to which I have clicked.both grids are from the Database (SQL2005) only. In the child grid am using a combobox and that is my headache...this part is working fine and the problem is in the child grid.
When I try to add a new data (at the sametime into the Parent and Child) its working fine and am able to insert data into the tables...
But when I want to edit a data in the child grid, the combobox is making problem.I selected a value from the combobox and go to the next cell OMG the combobox value changed to the corresponding ID of that instead of showing the text.But I neglected this as I was getting the correct value tat has to be inserted into the DB.
Now while editing the main data am tryn to add a new child data ( assume that there are few child data already and am adding a new one).When I click save the values in the combobox are retreived as string and am not able to update the database.This happens to the rows that were already there.the reason is because of the strange behaviour of Combobox in the grid..
Am after this for 2 days and still after this..
Also am populating the combobox from the DB only.
Find the code below, how I did the combobox population

So am back again with dattagridview and comboboxes...sorry for the troubless.. Now let me come to my scenario aka problem..I have 2 dataviewgrids in my WINDOWS APPLICATION FORM (VB.net).The first grid populates some data from the SQLSERVER 2005 DB.When I click on any cell of the first grid, my second grid shows up and populates with the data corresponding to the cell which I have clicked in the grid 1.This is working perfect and so far so good.In the second grid I have 3 combobox columns and some textbox columns..The three combobox columns in this grid are also populated from the DB only usng datasets and datasource.In the first Combobox Column if I select one value, then the corresponding values are filled into the other textboxcolumns.This is also working good.The other 2 comboboxcolumns are also populated from database using different datasets..
Am about to add a master data ( i.e data into the first grid).it got added and after that a msgbox pops up sayn u must add data into the second grid as well.so the user is adding the data in the second grid.(all works except the new requirement).he added something into the first row by selecting the comboboxcolumns and also editing the other columns in the first row.(he havent saved this row.This will happen when he clicks the save button in the form not in the grid)he goes into the second row .Now here he should not see the item from the combobox1 which he has selected in row1.

DataGridView TIPs has TextBoxes and ComboBoxes in it and the data comes from an SQL table. I see how to get or set the cell values that come from the ComboBoxes using Item, but how do I access the actual ComboBox events and properties?

I have a combo box having multiple items and I want by typing the item should select automatically and combo box style should be "DropdownList" type.Let�s say I am typing "I" then country like "India", "Indonesia�,� Italy" should sort automatically. It is happening by default in VB.NET for one character.But I want If I type "India" this should select "India" instead of "a...." because my last character is a. in VB.Net it is selecting country like starts with "a�. But I want the full typing option should be present for the combo box.

This seems to be the toughest thing I've had to search for. It seems there's not a good thread that clearly explains how to add items to a combo box that's bound to a SQL Server table (of course, I'm a newbie so I'd like a step-by-step on how to get it done).

I started a Windows app using all code for database connection and validation. However, it was always losing the formatting that I had set at run time. So I thought I would use the long tedious process of using all of the studios objects with minimum code.
I am now at the position where I am mostly happy with the layout and how this operates. However, I want to be able to add a non-databound value to a databound combo box. I have set the properties for the combo box in the combo box tasks.
Also, I want to add the ability for the user to update that table that is bound to this control, when a value is not in the list. I know that there is a NotInList event in Access, but I can not find it in VB.Net. I did get so far with updating from the combo box using the Leave event. However, when the database was updated the control could not find the ID in the Clients table to save to the Quotes table.

I am totally new to VB.NET and Visual Studio. I am creating a new form, which includes a combobox. I have figured out how to add the items to the combobox using the properties box, but I would rather code them. I tried the below code, but no luck. Any ideas what I am doing wrong? Me.cboSTATUS.Items.Add("A")

On my first form, I have a combobox that is bound to the Locations table and displays all the different locations. Once a location is selected, a 2nd form is loaded which has textboxes which are also bound to the Locations table and are populated with the corresponding data.
Here's my issue: on the 2nd form, I have combobox that is bound to the Offices table. Currently, when this form loads all the available offices, displaying with the first office in the list. I need it to populate with the correct office based on the selection made on the combobox on the first form. I guess what I'm asking is, how does one bind a combobox to a foreign key b/c it is the foreign key, office_refnbr, from the Locations table that needs to display in the Office combobox.
I've tried a variety of bindings, including:[code...]

I am successfully hiding a combobox, based on the selection of another combobox. However, I can not get the label of the combobox to hide as well. The code I am using, which is basically the same code for hiding the combobox itself returns the following error:
Error 1 'DOCUMENT_EVALLabel' is not a member of 'WindowsApplication1.Form1'
Here is the code I am using for the label:
Me.DOCUMENT_EVALLabel.Visible = (EVALUATIONComboBox.Text = "Text")

Basically, I want the Items property to get its items from the AllSystemSources.
But I don't know how to do this.

I have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.

I am having a problem to get the results of a combobox when the user uses the tab key to exit the combobox. The combobox uses a database as the datasource. When the user uses the mouse to click on the selection the selectedindex is set proprerly, however when the user will enter some text and presses the tab key, selectedindex is set to -1.
I have attached some test code to duplicate the issue.

I have a combobox on a datagridview on my form. The problem I encounter is I have to click the button twice to see the items at the dropdownlist rather than once at runtime. Is there any change I can make probably in properties of the datagridview / combobox to show the dropdown list by clicking once rather than twice..

I though the problem was resolved but unfortunately is not.. I added this code to my form; Me.DgvReturns.Item(6, 0).Value = Me.DgvReturns.Item(5, 0).ValueThis Only affects the first line of the datagridview.. The second, third, fourth etc etc records are not reflected. Therefore, the vale of the textbox is not shown on the combobox.
