I am having issues with a combobox set to:
AutoCompleteMode = Append, AutoCompleteSource = ListItems.
Example: Items in the combo are: "Average", "Good", "Poor". If "Average" is selected in the combo, then I type "G", "Good" will autocomplete. But if "Average" is selected, tab out of the control, then tab back into the control, then I type "A" nothing is autocompleted. It just shows "A" in the combo.
I have problem with my combobox and suggest list poping up. Im taking data from datatable then i start to type and list is poping up if i select item form that list by moving arrows up and down and then press TAB than all is working ok but if I select item by clicking mouse then the item I choose doesn't show text but empty field.

View 1 RepliesI'm struggling to meet a demand from my supervisors.Basically there are places in our project where there is a big selection of options. The most concrete example is choosing a city in the world. The items are hundreds of thousands.Using standard winforms controls and properties, one can search through a list fast.The problem is that we're using a concatenation of city&district name for all the items. Essentially PREFIX autotomplete works but does not work as needed. The task is to filter and show items by any given string in any part of the item. Essentially a FULL TEXT search in the combobox.Does anyone have an idea about switching autocomplete sources in runtime relatively qiuckly and handling the suggest/suggestappend event?

I have a combox that is run-time bound to a table that is run-time built and populated from a text file. I have set the combobox autocomplete mode to suggest and the source to list items, but only the 1st item will work. Ok so here's the code:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
The file is a text file with a list of the 50 states and their abbreviations in the format : stateName - abbr.Now what happens is the data is displayed correctly, but when I begin to type a letter for the autocomplete the only letter that shows anything is the "a" and it will only show the very first item in the text file.Everything else does not display with the autocomplete, but does show in the list. I have tried variations such as adding the data as items like this:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
This way does not allow any autocomplete when I begin typing but everything is in the list. I've also tried converting the table to a customautocompletestring and still the same results.The only way that I have been able to get it to work is be entering each state as an item: state_cmbx.items.add("Michigan - MI"), then it works correctly.Also the combobox dropdownstyle is set to dropdown, and I'm using visual studio 2010 ultimate and coding using VB.
How to make a combobox autocomplete?
View 9 RepliesI am having a problem to get the results of a combobox when the user uses the tab key to exit the combobox. The combobox uses a database as the datasource. When the user uses the mouse to click on the selection the selectedindex is set proprerly, however when the user will enter some text and presses the tab key, selectedindex is set to -1.
I have attached some test code to duplicate the issue.

I have tried searching on if it is capable to do autocomplete in a combobox in the datagridview control. I was planning to use the combobox in the grid itself. There is a property to set autocomplete true/false but I cannot get the cb to let me enter text to find. It only selects on the first character of items in the list.
View 4 RepliesI have a ComboBox which is bound with a DataSource from (obviously) a Database. However, there are 659 different entries inside this Database and I was hoping to tack on AutoComplete.
I tried setting the Source to the ListItems since, after initialization and the data is bound, all the items necessary are in fact inside the ComboBox so I had assumed that it would pick that up. I was wrong. I tried using a Custom source but VS errored out saying that I couldn't do that since the ComboBox was bound.
My question is, how can I utilize AutoComplete's "Suggest" mode with a bound ComboBox?
What is the real mode , protected mode , supervisor mode and the hypervisor mode ?

View 6 RepliesIn my word processor I have an 'Open' option on a menu strip. Here is the code for it:
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
With ofdFile

For some reason when I press the 'Open' item and open the ofdFile dialog box .txt files do not appear even when I have the 'Text Files' filter selected However, when I use the 'All Files' filter they appear. And the 'HTML Files filter is also working properly.Why are the .txt files not appearing when I use the Text Files filter?
I don't even know where to begin describing this. I have a project, that uses settings, for some paths, settings that I retrieve with the My.Settings. function.In my laptop, when I change the .exe.config file, the settings are updated accordingly, but when I try that on the production server, it just shows the default value used while compiling.
I tried changing the solution configurations to debug and other custom configs with no effect.Tried to use the same folder copied and pasted without version control, still the same result.Tried a co-workers laptop, by using the last svn revision, it works there too. But on neither of the servers works.
I cannot figure out why my calculation is not working. I am doing for 1 to 12 and it gives me 12 inputs but counts my entries as 13? What am I missing. If I change it to 0 to 11 same thing. I am not sure what the issue is, but I cannot see it, and am not sure where to look.I need to end up with 12 cycles through and intEntries to be 12.

I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.

View 4 Repliesi have a windows forms app which displays a bunch of records from my sql database. when i modify records in the grid and click on save, all changes are saved EXCEPT the changes made to the currently highlighted row. they aren't written out the database until i exit the actual program, despite clicking on my save button.so for example, if i change 5 different records in the grid, and click on save, and then click on refresh to reload the data from the database, 4 out of the 5 are saved correctly, but the row that is currently highlighted (meaning, the last row i changed) still has the old data.My code for the save button look like:
