Normally when I populate a combobox I do so by binding it to a datatable and assigning a display member and value member. I would like to do the same thing by adding pairs of items in code.I tried using a key-value pair, but that didn't work. The combobox displayed both the key and the value. I would like to have it just display one of the values and leave the other one invisible to the user, but available to me as a key.I thought about creating a custom class with two properties - one to use as the display member and the other to use as the value member. But before I re-invent the wheel I thought I'd check to see if there's already something there in the framework that I'm missing.

I have an application which consists of labels, textbox, combobox and buttons. The combobox and buttons loads after the contents of an Excel file is loaded into the application.However if the form is resized before the loading, the position of the combobox and the buttons changes even though all the controls are locked. The position of the labels and textboxs remains the same. Can anyone figure out any reason for this anomaly?
View 4 RepliesI have been searching for a while and not able to find anything useful on how to approach this issue.I have a ComboBox on a form and what I am looking to do is when the ComboBox has the cursor focus, it automatically opens up and displays the options. Just as if you clicked on the ComboBox. I was considering PerformClick but the only problem is, I believe PerformClick is only available for the Button and no other control.

1. I type the first letter of the username i want in the combobox text area, the combobox drops down and shows me all the usernames starting with that letter. I scroll down to the name i want (as i scroll down, the text area holds each name but the SelectedIndexChanged event does not fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
2. I do the same as above, but instead of hitting Tab key, i hit the Enter key. The same thing happens and i get the result i want.
3. This time, i first click on the dropdown arrow of the combobox such that it shows all usernames starting from the first name. I then type the first letter of the name i want. I saw that another drop down appeared in front of the first one and it was a smaller subset of names starting with the typed letter. I scroll down this smaller dropdown to the name i want (here also, as i scroll down, the text area holds each name, and the SIC event doesnt fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
4. I do the same as #3, but this time i hit the Enter key instead of Tab key. But this time, the combobox text blanks out and the SIC event is not fired (although the name showed up just before i hit the Enter key). So i do not get any results back.

View 3 RepliesI have a DGV bound to a bindingsource with a column that uses a DataGridViewCombobox, that has a DataTable for it's datasource.

Now when I try to load the form that contain the DGV, I get an error "DataGridViewComboboxCell value is not valid" for each row that contains the value I removed from the DataTable.It seems the value of the column must be a member of the combobox Listitems. Is there a way to allow values not in the combobox ListItems. I don't want the combobox listitems to be locked in for the life of the application.

I have 2 forms. The first form has a label on it. The second form has a combo box, a text box, and a button on it. In the second form, when I select the label name that I want to edit, I type in what I want to change the label name to in the textbox and I click the button. Now this goes through flawlessly except I want the combobox item to change to the NEW label name. I've been able to do that but when I close the form in run-time and open it up again, the previous label name appears once again. Is it possible to make the combobox add the new label name and KEEP it in its collection?
