ToolStrip ComboBox Using Data Bound Item?
May 4, 2009I have created a search/query facility after watching one of Beth Messi's videos. I notice that we can convert the textboxes on the auto generated search toolstrip to buttons, comboxes, etc. So, when we wanna search for a data in the datagridview, we enter a keyword. I wonder if it is possible to change the textboxes to comboboxes and make it bind to the datasources, so that users can use the drop down, instead of typing?

View 5 RepliesVS 2008 Changing Bound Data When Entering Text In ComboBox?
Aug 9, 2009I have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.
What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.
Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.
I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?

ComboBox Set To OwnerDrawVariable Causes Item Text Mis-encoding End Displaying Blocks?
Apr 30, 2012I have a problem with combobox. I set the DrawMode into OwnerDrawVariable so I can draw items seperately with styles, but the characters of the items are now displaying blocks. The block characters are none ASCII. It used to display well but not now and I don't know what caused it to happen. I didn't change my system locale. At the same time, other combobox that have Normal DrawMode displays nicely fine.
My custom drawing code:

Asp.net - Add New Item To Already Bound ListView In ASP Net?
Dec 19, 2011My overall goal is to add fake/unbound items to a listview control (for final HTML Table output reasons). This is a code behind solution. Users will not be adding items as it will be outputted in a rigid table.
I have looked at several examples and while this is easy for a dropdown it is not for listview.
The code below works without error, but my item is not shown on runtime. I think the class is not setting the item fieldname correctly, but I can't figure out the right syntax to fix it.

View 1 RepliesDeleting Bound Item From DataGridView?
Oct 18, 2010I have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..
So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?
EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..
C# - Can A DataGrid Column Be Two-way Bound To A Dictionary Item
Mar 14, 2012I am working on a bound DataGrid that displays data from a database. I'm using Silverlight 5 if that helps. Currently all the data is stored in a Dictionary within the my entity object. Using the Property[Key] syntax for the binding path binds properly for display purposes. But the column acts like it is readonly when trying to change a column value in runtime.
Public Class Entity
Public Property Attributes As New Dictionary(Of String, Object)

My only thought right now is to store the column values in ordered lists and display them using an index rather than key. But I would really like to know why the key isn't working.

Bound ListBox Item Count Changed Event
Feb 22, 2011I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?
