WebDropDown AutoPostBack Problem

Jim posted over 13 years ago

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

This issue is driving me absolutely bananas.

I have added all of the properties recommended by Infragistics team members. The problem persists.

Here is my tag:

        <ig:WebDropDown ID="wddRouteBookID" runat="server" Width="240px" StyleSetName="Harvest"
            DropDownContainerHeight="300px" DropDownContainerWidth="400px"
            EnableAutoFiltering="Client" AutoFilterQueryType="Contains" AutoSelectOnMatch="False"
            EnableMarkingMatchedText="True"
            EnableCustomValueSelection="false" EnableCustomValues="false"
            EnableClosingDropDownOnSelect="false" EnableAutoCompleteFirstMatch="false"
            KeepFocusOnSelection="false">
            <AutoPostBackFlags ValueChanged="Off" SelectionChanged="On" />
            <ClientEvents Focus="wddRouteBookID_Focus"  />
        </ig:WebDropDown>

Hi all,

Try also setting the following properties:
EnableCustomValueSelection="false"

EnableCustomValues="false"

Once you do so the control shouldn't postback anymore. I hope this helps!
