It still doesn't work correctly.  Here's my code:

 <form id="form1" runat="server">
    <div>
      <asp:ScriptManager ID="ScriptManager1" runat="server">
      </asp:ScriptManager>
      <ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px"  TextField="Prod_Code" ValueField="Prod_ID"
        AutoSelectOnMatch="false"  EnableAutoFiltering="Client"
        OnSelectionChanged="WebDropDown1_SelectionChanged"
        DataSourceID="SqlDataSource1">
        <AutoPostBackFlags SelectionChanged="On" ValueChanged="Off" />
      </ig:WebDropDown>
   
      <asp:SqlDataSource ID="SqlDataSource1" runat="server"
        ConnectionString="<%$ ConnectionStrings:TravelerMakerGUIConnectionStringXXXX %>"
        SelectCommand="SELECT [Prod_Code], [Prod_ID] FROM [ProductCodes]">
      </asp:SqlDataSource>
   
    </div>
    </form>


The desired behavior is: A postback should only happen when:
1) an item is selected with the mouse (this works)
2) Only when the <enter> key is hit (not working) - postpacks also happen at other times.

If the list is a bunch of part numbers like:
abc-123
abc-124
abc-125
def-123
def-124

Now, using my code and part numbers from above, select abc-124 with the mouse.  a postback happens - this is correct.

Now, pretend that you made a mistake, and you really wanted one of the def-123 parts.  So, rather than use the mouse, you highlight the abc-123 item, and start typing 'D'.....     A postback happens.   I did not select a full partnumber, I just typed a 'D', and a postback happened.  This postback should not happen, I did not select a part number.   

A postback should only happen if an item is selected with the mouse, or if I hit the <enter> key. 

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>

Went back and re-read every post in this thread in detail to make sure I wasn't missing something.  Can't find what I am doing wrong.

I am using 10.3.  I have a current subscription... just haven't upgraded to 11.1 yet.

Hello All,

Thank you for your valuable input on this matter. I would like to share with you that I’m able to reproduce this behavior and it  doesn’t seem to be correct. I am bringing it up to our UX and Development teams  for further investigation.

I will keep you informed.

Thank you very much!   Think we might see a solution in the next SR?

We've been using 11.1 which has this issue. I waited until Mid-November for ver 11.2. Downloaded the trial and setup a quick test site. Exact same problem still exists. My client was going to renew their subscription if it was fixed and get 11.2. Now they aren't going to.What a disappointment.

Unless a team member can tell me otherwise. Maybe there's a new property in 11.2 that I need to set to suppress the postbacks on every typed key?

Hello, I'm Using Infragistics Latest Version, I have the same issue With Web DropDown on Value Changed with IE 8 ,

Kindly Let me what is Causing the issue

Perhaps you can release a HotFix before the next Service-Release is released...

Thank you very much Konstantin!  Sitting on pins and needles waiting for the next SR.  Is there an ETA?
