I am adding items like this:[code]I can't figure out how to set the combobox column. And to top it off, since I changed the column from a text column to a combobox column, the grid is throwing exceptions, although it doesn't tell me what's wrong, it just tells me to handle the dataerror event, and all that I can get from that is e.Context = 3 and I can't find out what that means. Probably a type mis-match, but I can't find the proper way do select from the combobox. The rows add OK, but when I scroll the combobox column into view the first item is selected then the errors get thrown.

View 5 RepliesI have a drop-down ComboBox, where the values are a range of indexes, followed by a key value. So one line looks like:01 : 01010101010101010202020202020202
I have set the ComboBox up so that on the form, only "01 :" is displayed, but the DropDownWidth allows the entire string to be seen when the dropdown arrow is clicked.However, once that is done, I am left with "0202" (the last four characters) showing in the ComboBox, rather than "01 :" until the control loses focus. How can I force "01 :" to display?

I have a Combobox in a Windows form that has a DateTime value as the Display Member and the Room Number as the Value member. When the user makes a selection in the combobox, a textbox is populated with the corresponding room number. There are some instances in the combobox where there are identical Display Member values. When a user selects one of the duplicate values and moves the mouse cursor away from the combobox, the combobox always defaults to the first of the duplicate items.
Example:
Here are the values that are currently populated in the combobox:
Display Member Value Member
02/25/2010 9:00AM 1
02/25/2010 9:00AM 2
If the second listing in the combobox is selected (the item with the value member of 2), and then the user clicks away from the combobox, the value default to Value Member 1.
Is there anyway to keep duplicate display members in a combobox while keeping the proper value member selected?
