Hello,

I have a textbox that is linked to a custom source. The textbox autocomplete features is working just fine. I just have a question on some events that I can use to know when the user has selected the suggested text from the autocomplete dropdown box. I am able to check for user hitting Tab or Enter just fine, now I need to be able to know when the user is clicking on a specific item in the suggestions dropdown box. Where is this event stored? Or how can I monitor this click.

Anyone ran into this before? Any help is appreciated. Thanks!

double click on your dropdown box this will create a comboBox1_SelectedIndexChanged method so when ever the user select the dropdown box and selects an item you can store that value

csharp

string dropdownboxtext= string.Empty;
private void comboBox1_SelectedIndexChanged (object sender, EventArgs e)
{
     dropdownboxtext= comboBox1.SelectedItem.ToString();
}


dropdownboxtextwill contain the value of the selected item in the drop down

I'm not following for some reason, I don't have a combo box control that I am using, I am using a TextBox control for my autocomplete.
I have created a custom auto complete source through a database loop. AutoSoureMode is set to SuggestAppend. Doesn't this mode of Suggest tell the textbox somehow to add that dropdown box with the suggested items. It is that magical dropdown box there that I am trying to access the events of. Does that make any sense? Sorry if I'm being vague here.

I appreciate the help.

zakary,

No Problem. My fault in my original explanation.

I figured this is hiding somewhere, but I have no clue where to look for that. My end result was just when the user does one of the following to add the suggested text by the autocomplete to a listbox. So Tab & Enter, and then when the user Clicks on the suggested text, I.E. if the item they need is two or three suggestions down in the dropdown list.

Thanks for your help!

Hi had the same problem... here is how i got it working. Add a key down event to your textbox. in the keydown check if the enter key was pressed - clicking on a suggested text line is same as pressing enter -- in the if statement you can then get the text with textbox.text. cheers ewald
