Multi-Column ComboBox that binds to it's Value and Display Members for the drop down

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :WPF
I'm looking for a MultiColumn ComboBox solution as well. I've seen a lot of people talking about using Templates and I have to admit I'm not entirely comfortable with using Templates yet in WPF.

What I'm looking for specifically is a ComboBox that simply shows a two column drop down that displays the values resolved from DisplayMemberPath and SelectedValuePath for each item of the bound ItemsSource of the ComboBox. Once one of the items is selected I'm looking for the SelectedValue only to be displayed in the Text area.

Below is a crude diagram to explain what I'm looking for.

|CODE1 | Display value 1 | |
|CODE2 | Display value 1 | |
|CODE3 | Display value 1 | |

I've fumbled around using RelativeSource and a few other things but nothing works so far. If anybody has a clue about different ways to implement this I would love to hear them. A quick example using templates would be wonderful but also note that I'm planning probably to make this a reusable control in our solution since this is a common paradigm in our UI that I wouldn't want to have to repeat on each Window or UserControl in various projects.

ActiveX and Visual Basic: Enhance the Display of Long Text Strings in a Combobox or Listbox


The combobox and listbox controls in Visual Basic have no built-in support for displaying text strings that are too long to fit in the visible area of either control. This article describes several techniques to improve the readability of long strings in each control. The first technique uses tooltips to display a combobox or listbox item. The other techniques, which use various Windows APIs, include adding a horizontal scrollbar for a listbox and determining the necessary width of the longest string given the font attributes of the text. The required steps are described for both comboboxes and listboxes.

Use BDC data in list as multi-select column

I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?

wss2.0 update/delete/hide lookup column that does not display any values


Hi All,

I have a document library that contains a Category column that is a lookup field. This is a default column that is a required field when uploading documents to the document library. The Category column is empty and I am unable to amend, hide, make it not required or delete it.

I have gone to Modify settings and columns -> clicked on the Category field to edit, but there is no option to amend the content or delete it. I am only able to amend the Column name and Description.

Since then, I have amended the column name to eg. Category1 and created a new Category field as a lookup and linked it to the correct list.

The problem I am facing now, is that I cannot hide, delete or make the Category1 (old Category) field NOT required. Either I would like to update the original field to display the correct values or alternately hide, delete or make the column not required.

Please help.

wss2.0 edit drop-down menu does not display


Hi all

I have a user who is unable to view the edit drop-down menu next to documents in a document library.

The user was able to view the drop-down before, but it seems since upgrading to either Office 2007 or IE7 that the problem is occuring. The user is an administrator on the site so it doesn't seem to be permissions issue.

I have had the user run an Office Diagnostics but this did not resolve the problem.

Any ideas please?

ComboBox Display list does not update if a datasource is a boxed string

I have a combo box databound to a BindingSource bound to a List<Holder> it has Holder.Name as its display value. I also have a text box bound to Holder.Name but if I change the text in the text box it will not change what is displayed in the combo box. Changing selected items and changing back will show the updated text in the text box but will still have the old value displayed in the combo box. How do I make the item in the combo box update? namespace Sandbox_Form { public partial class Form1 : Form { public Form1() { InitializeComponent(); lstBroken = new List<Holder>(); lstBroken.Add(new Holder("test1")); lstBroken.Add(new Holder("test2")); bsBroken = new BindingSource(lstBroken, null); cmbBroken.DataSource = bsBroken; cmbBroken.DisplayMember = "Name"; txtBroken.DataBindings.Add("Text", bsBroken, "Name"); lstWorks = new List<string>(); lstWorks.Add("test3"); lstWorks.Add("test4"); bsWorks = new BindingSource(lstWorks, null); cmbWorks.DataSource = bsWorks; txtWorks.DataBindings.Add("Text", bsWorks, null); } } public class Holder { public Holder(string name) { Name = name; } public string Name { get; set; } } }

WPF Datagrid Combobox column

Hi, I am creating a WPF Datagrid with the combobox column in it. All the datagrid binding and combobox column binding works fine without any problem. But, when I select a value in the combobox column and move to the next column or row, the value is reset to the previous empty selection. Am I missing anything here? Please find the code snippet that I have used below. <dg:DataGridComboBoxColumn x:Name="technicianname" Header="Assigned To" ItemsSource="{Binding}"/> technicianname.ItemsSource = dtTechnicianInfo.DefaultView; technicianname.DisplayMemberPath = "TechnicianName"; technicianname.SelectedValuePath = "TechnicianEid"; Thanks in Advance!!!

Best way to display data of a single column from a Sharepoint Custom List

I'm trying to create pages that will automatically populate with data pulled from a sharepoint list (like title, department, contact info, etc.).   I'm using publishing pages. What would be the easiest way to do this, and how would I specify which data to pull from the list? For example, the page would be set up like this: [Title:biology] [Department:biology] [Contact Info:biology]   and when the page loads, it would look like this: Biology Lab Biology Department 123-456-7890   I want it to just pull the data -- I don't want a list view or anything like that.  I need this page to look pretty, and I need the each column's data to show up in a very specific place. How could I make pages that would do that?
