Hi. I'm relatively new to wpf and I quite don't understand binding yet. I want to have several combo boxes in my application with the same items. The basic solution would be to copy paste but that just isn't good practice. So I thought to put a static resource with the content I want and bind all combo boxes to it. It compiles and runs ...
It seems nobody has yet found a way to set the comboboxitem as selected with a SelectedItem="Binding Property". Is the solution to use a IsSelected Property in the ViewModel object within the combobox itemssource ? ...
I have a "populate combobox", and I'm so happy with it that I've even started using more comboboxes. It takes the combobox object by reference with the ID of the "value set" (or whatever you want to call it) from a table and adds the items and their respective values (which differ) and does the job. I've recently had the brilliant ide...

I'm a reasonably-experienced Flash developer, now needing to use Captivate. In order to emulate some software functionality in an exercise, I need to create a combobox control (what Captivate calls a "widget" and Flash calls a "component"). The combobox that ships with Captivate is very different in appearance from the one I need to im...

Everything works well, except that when selection change happens on the combobox, the selectedvaluebinding source is not updated immediately. This happens only when the combobox loses focus. Has anyone run into this issue and any suggestions solutions ? Here's the xaml for the ...
hi, I'm using GWT-EXT combobox. My problem is when I render the combobox, it's having as many rows as it has values but all the rows are empty means text is not shown. Here's my code. Combobox cb = new Combobox(); cb.setForceSelection(true); cb.setMinChars(1); cb.setWidth(200); cb.setStore(store); // Store is perfectly loaded in co...
Hello. I have this code that adjusts the width of a comboBox drop-down: private void comboBox_DropDown(object sender, EventArgs e) { ComboBox senderComboBox = (ComboBox)sender; int width = senderComboBox.DropDownWidth; Graphics g = senderComboBox.CreateGraphics(); Font font = senderComboBox.Font; int vertSc...
The following code works as you’d expect — MyProperty on the model is updated when the user picks a new item in the dropdown. comboBox1.DataBindings.Add("SelectedValue", myModel, "MyProperty", true, DataSourceUpdateMode.OnPropertyChanged); The following, however, doesn’t work the same way and the model update isn’t triggered until the...
I'm working on a custom ComboBox for a project, and have the basic painting working. One of the remaining things to do is make it look like the default ComboBox in Vista and 7, when the DropDownStyle is set to DropDownList (looks like a button instead of a regular ComboBox). I read much about VisualStyleRenderer, read ComboBox.cs and Co...

I'm hoping to use an attached property to assign a command to the selection changed event of a combobox that is embedded inside a treeview. I'm attempting to set the attached property inside the hierchical data template for the tree but the command is not set and does not fire when the item in the combobox is changed. I've found that ...
In my application a ComboBox gets resized, so that it is smaller. How do I re-calculate the DropDownWidth property? I know how to set it, but I'd prefer to calculate the proper width because its contents changes. Preferabley, I was thinking of something along these lines: int iMaxLen = 0; foreach item in comboBoxList { iMaxLen = (...
G'day! I want my WPF ComboBox to display some alternative text when its data-bound selection is null.

hi Suppose that you have a win form with 5 combo boxes on it. Some one told me that you must have 5 data table in order to fill them one by one. It does not seem very logical and I think this will create ugly code. How do you fill them with data stored in Database? ...
