Aug 19, 2011I have a combobox on a form with the dropdownstyle set to drop down. Users can either salect a value from the list, or type in any value they wish. This all works fine.

Disable Some Items In A Combobox?
Jan 27, 2009Is it possible to disable some items in a combobox?Depending on the current mode that my application is in, certain items need to be enabled or disabled.I know that I could remove the items and rebuild the combobox but in this case I think that by showing the items greyed out it gives the user feedback as to what mode they are in and what options would be available to them if they decided to switch modes.
View 17 RepliesGet The Handle Of A ComboBox's Edit Control
May 29, 2009I'm inheriting a couple of the common WinForms controls and then manually repainting them so that they will correctly render over a WinForm with the Aero Glass effect enabled. I have this working well with the TextBox. I ran into a snag with the ComboBox though in that it would only repaint some of the control. I fired up MS Spy++ and saw that the ComboBox has an Edit control in it (that's not in it's control collection). I can repaint that Edit box, but I need to get the handle of it and a couple of my attempts have flopped. I found some code that used the FindWindowEx API passing the Comboboxes handle but for me it returns 0.
hwndEdit = FindWindowEx(Combo1.hwnd, 0&, vbNullString, vbNullString)
Basically, I need the handle of the edit control inside the combobox (once I understand how to correct get that then I can get the additional controls in other ones I want like the ListView). Here's the Spy++ screen shots to illustrate (from Spy++ I can see the individual handles).

VS 2010 - Using ComboBox To Update / Edit And View Saved Data
Apr 5, 2012I am trying to use the combobox to update/edit/view the saved data (in contact form) from sql server.
My Load_Combobox (in contact form):
Private Sub Load_Combobox()
'Type
cboType.Items.Add("Director")
cboType.Items.Add("Principal")
cboType.Items.Add("Project Manager")
cboType.Items.Add("Technical Manager")
[Code] .....
The problem now is when I saved a record into sql server (EG Technical Manager) and try to view back the saved data, it always show the first item (Director) in combobox. But, my sql server has saved is "Technical Manager" for that saved record.
C# - Populate ComboBox Edit Field With ValueMember But Show DisplayMember In The List?
Oct 12, 2011I have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
(DisplayMember, ValueMember)
"Foo - 1ab2" , "1ab2"
"Bar - 3cd4" , "3cd4"
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
void FillMyCombo
{
KeyValuePair<string, string> listValue1 = new KeyValuePair<string, string>("Foo - 1ab2" , "1ab2")
KeyValuePair<string, string> listValue2 = new KeyValuePair<string, string>("Bar - 3cd4" , "3cd4")
[code].....
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.
Extend A DataGridView ComboBox Column's Edit Control By A Second Tiny Button?
Jul 12, 2011I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
