I can't figure out how to get the WebDropdown to autopostback ONLY when I have actually selected an item.
Using your own example shows the problem that I'm having. Please go to this page:
http://samples.infragistics.com/2009.1/WebFeatureBrowser/contents.aspx?showCode=True&t=WebDropDown/WebDropDownServerEvents.aspx~srcview.aspx?path=~srcview.aspx?path=WebDropDown/WebDropDownServerEvents.src
Now, click in the webDropDown, delete the text, and type just a 'B'. An autopostback happens, and says that I have selected "Berglunds snabbköp". Which is not the case - the webdropdown only has a 'B' in it.
I don't want a postback to happen until I either hit <enter> or click on a item. To further clarify my need, lets say that you actually wanted to select the second "B" item, which is "Blauer See Delikatessen". I want to be able to type "Bl" and not have a postback happen after the "B".
In my case, I'm setting EnableAutoFiltering="Client", which will filter the results. So, I want to be able to type a "B", and the result is filtered, BUT no postback happens yet, because I haven't selected anything yet. Then I type"L" (which filters, so "Blauer See Delikatessen", is now the first item - the item that I really want, so I now hit <enter>. This is when I want the autopostback to happen - because only now have I actually selected something. Up until now, I've only been typing.
Thanks,Jim
Hi everybody,
I found a solution for this:
To cancel the postback when you 'unselect' an item, set the clientside selectionchanging event of the webdropdown to the following javascript to solve this:
function selectionchanging(sender, args) {if (!sender._activeItem) {args._cancel = true;}}

I think that setting Autopostback=false gives the desired behavior; Does anyone know how to trigger a postback after a selection is made?
hi,
try this: function selectionChanged(sender, args) { if (sender._activeItem != undefined) { __doPostBack('<%=YourWebDropDown.ClientID%>',''); } }
