combobox

问题 I have a WPF ComboBox that binds to a set of data. I do not have permissions to modify the control directly, nor can I change the data. I'm returned 1 item in my ComboBox, but there are actually 2 rows; the blank row and my expected value. Both appear to have an index value of 0. I don't want to see this blank row, just my expected data in the ComboBox auto-selected. I have looked through everyone's related posts in here, but none of the solutions have worked for my case.

问题 This is in continuation of a previously resolved query related to Access Database values in Combo box. The code below is working fine. i.e. it gets the data from an Access table column into the dropdown of a combo-box. What I want is how to assign those values against the Combobox.SelectedIndex? I added TagComboBox1.SelectedIndex = 0 but I want something that will automatically assign Index to the values populated in the combo-box dropdown. The source table is tag_data ' Key Column is tag

问题 Have a look at this screenshot first to see what happens: What you can see on this screenshot is what I have done already.. But I want to add a few things more.

问题 I have a datagridview with lots of data, and when I add a new line, the first column's last row creates a new ComboBoxCell which contain four items. But I can't set the default value ("DropDown") for the combobox. Every time I must manually select "DropDown". What is the solution? DataGridViewComboBoxCell dgvCell = new DataGridViewComboBoxCell(); dgv[1, dgv.Rows.Count - 1] = dgvCell; string[] controltype = {"DropDown", "CheckBoxList", "ListControl", "Tree" }; dgvCell.DataSource = controltype;

问题 I'm sorry the title is badly worded and change it if you must, but this is what I am trying to achieve. I have styled a combobox and added some items: When an item is selected I wish only the title to be displayed, at the moment the whole content is displayed: I have been playing around with using Tags to define the textblock with text "Title" as a header and display that however it's not working :(. Here is the XAML Styling within app.xaml, I haven’t placed in a resource dictionary yet as I

问题 I need to open a specific form by a click on a subform record name. The name in the subform is showed as a combobox with ID and Name as columns. I did like this: Private Sub ID_Prodotto_DblClick(Cancel As Integer) Dim Id As Integer Id = Me.ID_Prodotto.Column.Value DoCmd.OpenForm "Prodotto", , , "ID_Prodotto = " & Id End Sub But Access requires me to manually insert the ID Field Value as I click on the record.
