View 2 RepliesDataGridView ComboBox Will Not Dropdown
Oct 27, 2011I am using VB.net 2005. I have a DataGridView with several columns. One of the columns is a ComboBox. What I want to happen is when I populate the DataGridView by binding it with the DataTable I want the ComboBox item that is in the DataTable field to be the one that is shown as selected in the drop down. Then if the user wants to change the value they select a different one from the DropDown (and I will perform some update action). My code displays the correct DataTable item in the ComboBox, but the ComboBox will not drop down so a different item can be selected.
This is the code where I set up the ComboBox in the Form_Load and add all the possible items that can be in the DataTable Destination field.
c10 = New DataGridViewComboBoxColumn
c10.Name = "Destination"
c10.DataPropertyName = "Destination"
c10.MaxDropDownItems = 5
c10.Items.Add(" ")

Get More Out Of A Dropdown DataGridView ComboBox?
May 24, 2012For this project I am using Visual Basic in Visual Studio Professional 2008 and SQL 2005 Express.
I have a table in SQL 2005 Express with 4 columns. These are ID, ProductCode,ProductDescription and Price all included in a dataset called ProductsDateSet. The ID column is obviously an integer and the primary key. The ProductCode and Description are both nvarchar(50) and the price is a money column.The table is called Products.

This code produces a ComboBox that contains a DataGrid with two columns and seems to look fine. Although when you click on the ComboBox and select one of the rows in the DataGrid the selection in the ComboBox doesn't work properly. (It just shows the colum headers.) I want the value in the first column of the selected row to appear as the ComboBox selection.

View 3 Replies.net - Intercepting Combobox Dropdown?
Aug 15, 2009Urgh, I have spent the last couple of hours on this now. I normally end up finding the answer from a bit of Googling, but not with this one. Bit of a headache.
My questions:How can I catch when a user clicks the dropdown arrow on a combobox and prevent the dropdown list from being displayed.How can I then clear and populate the dropdown list and display it programmatically?
I have one agent program remotely connected to a server over the internet. When you click the dropdown arrow on the agent, it queries the server to determine what needs to be in the dropdown list. It then displays the dropdown list. The comboboxes act as filters for the subsequent comboboxes on the GUI. A delay in displaying the dropdown list is perfectly acceptable while retrieving the data. Initially querying all the possibly entries in the dropdown list is not an option because there are so many! Needs to be comboboxes compared to listboxes as the user may also type an entry that is not in the list.

View 1 RepliesDropdown ComboBox With Predictive Text Option
Jul 21, 2010I have a combobox and have 10 items in it (Name of countries). I want to make the users life easy so that when they click inside the combobox and start writing then the text box will start predicting the rest of the text in the combo box. i.e. if i start writing "U" then the textbox will start predicting "UK" as "UK" is already a pre-populated item in the combobox.
How can I restrict the user from selecting only values within the pre-populated items of the combobox. Bearing in mind the combobox allows the user to write inside it (for the benefit of predictive text). But lets say there are values of UK, USA then I dont want the combobox to accept the value of "Ukraine" when the user clicks away from the combobox.
