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 1 RepliesHandling RowDataBound Causes Dynamically-bound GridView To Show Only First Record
Jun 28, 2011I have a GridView control which I am dynamically binding to a DataTable which is populated by a query built based on a set of selected options.What I am trying to do is simply handle the RowDataBound event in order to format specific rows based on the value of a database field. The code in this event handler works fine. My problem is, calling this event causes the GridView to only display the first record in the DataTable, almost as if the Gridview stops after binding to the DataTable after the first row is bound. I have attempted adding the handler dynamically, but I get the same results.I know for a fact that there is sufficient data being returned (the DataTable fills with all of the records, and the GridView shows all the records fine when not touching the RowDataBound event).
I'm adding the handler immediately after generating the query, filling the DataTable, and binding the GridView: [code]I have also determined that, when handling RowDataBound, the GridView's DATABOUND event never gets fired; it seems to stop binding right after binding the first row.
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)
End Class

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.

View 5 RepliesBound 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?
