May 28, 2010I have just received an interesting feedback from a VB.NET customer using our product - for some reason intellisense hidden a certain enumeration value.After a small testing I have found that this is likely a bug in IntelliSense: [URL]..To be honest, I did not expect this problem with such a basic stuff like this. Have you seen this in the past? For me, it doesn't work in all VS versions...

View 1 RepliesHow To Retrieve ComboBox Value
May 9, 2010I have a combobox (dropdownstyle=dropdownlist) with 4 items in it (defined in design time). The items are the following:
1;0,1;0,01;0,001
I read a row from a database (which contains a field with one of the 4 items) and I want to display this value in the combobox.
I use this method:
cmbtizedesh.SelectedIndex = cmbtizedesh.FindStringExact(pgreader(4))
But it works only, when the field value is 0,001. In any other cases the combobox value remains empty (the result of the FindStringExact function is -1). The pgreader is a NpgsqlDataReader object and retrieves the right values.

View 1 RepliesRetrieve MemberValue From ComboBox?
Dec 20, 2011I have been working on this for three days now and just can't find a simple answer. (It really can't be that hard to do surly). but now I can't see the trees for the forest anymore.
I populate a Combobox from an SQL database, this works fine and the data shows up fine in the Dataset Visualizer.
ComboList is called cmbStateList
Two Database fields
DisplayMember "State"
ValueMember "ID"
What I want to do is simply return the ValueMember of when an item is selected from the combobox. When I use "cmbStateList.SelectedValue" in the cmbStateList_SelectedIndexChanged what is returned is the index or position of the item in the list, not the ValueMember ("ID") field of the data.

Using Enumeration Across Projects?
Dec 4, 2009I have a Windows Forms UI, a Class Library, and a WebService. I need to be able to pass an Enumerated type through each of these layers (SystemType). For instance, the UI passes the type to the class library, which then passes the type to the Web Service.My question is, where do I define this enumeration type so they all know about it.
Options so far:
- Each project contains the exact same enumeration.
- Put the enumeration in its own project and reference this assembly from each of the other projects.

View 2 RepliesThe Given Key Was Not Present In The Dictionary. - Enumeration?
Aug 15, 2011I've been getting the following error from time to time and have been unable to determine the cause of it:"The given key was not present in the dictionary."The line that this is occurring on is:If CType(ViewState("FieldType"), MYClass.FieldType) = MYClass.FieldType.ShowOnDirectory ThenI have no idea as to why it is throwing this exception on this line. I thought that perhaps an invalid value was being placed in the ViewState so I tried while debugging setting the value to Nothing and setting it to a value that wasn't in the enumeration and it still works. I was originally storing the enumeration in ViewState and then went to storing just the Integer equivalent in there
