Hi,
When the page loads the WebDropDown is populated with a dataset which is then set to nothing.
When I select a value in the table in the dropdown I populate other textfields based on the values read from the selection in the table in the dropdown.
After that page is posted back, the values in the table in the webdropdown are no longer visible but when selected the values from the selected item do populate the textfields correctly.
It seems that the data is not visible but is there to select from.
Does anyone have any suggestions, I have pretty much exhausted my options?
Thanks!
Hello raghumuvvala,
I've reproduced the described behavior. The resolution for it is if you bind the control on each postback not only at the first time.
Best regards,
Hi
I am using webdropdown with itemtemplate and on the postback i cannot see the dataitems but can select them i am doing a databind on every postback too can you please let me know if we need to do anything else.
<ig:WebDropDown runat="server" ID="ddlCSModel" Width="200px"
loadingItemsMessageText ="loading..."
AutoPostBack="true"
DropDownContainerHeight="150px"
DropDownContainerWidth="500px"
OnSelectionChanged="ddlCSModel_SelectionChanged"
>
<HeaderTemplate>
<table style="width: 100%; height: 40px; background-color:DarkBlue;color: White; font-size: 20px; font-weight: bold;" cellspacing="0" cellpadding="4">
<tr>
<td style="width: 350px;">
Model Name
</td>
<td style="width: 150px;">
As of Date
</tr>
</table>
</HeaderTemplate>
<ItemTemplate>
<table style="width: 100%;" cellspacing="0" cellpadding="4">
<tr style="border-bottom: solid 1px #ff0000;">
<%# DataBinder.Eval(Container.DataItem, "MODEL_NAME")%>
<td style="width: 150px; padding-left: 10px;">
<%# DataBinder.Eval(Container.DataItem, "AsOfDate")%>
</ItemTemplate>
</ig:WebDropDown>
I made all the same changes and am definitely using version 10.2 only.
Now when I hover over the dropdown arrows on the webdropdown, they flicker.
It seems like the size is getting slightly larger and smaller very rapidly giving it the flickering effect.
I can however eventually get a click event to trigger and when I do it a second time again the data does not appear. So I still have the same problem in addition to the new problem of the flickering.
I am not doing a databind of the webdropdown except for on every postback in the page_load event.
Hi John,
Great! It's nice to hear that the issue is resolved. In my previous post I addressed Jay's issue which is similar to yours. If you do not experience any issues with this version my advice is to keep it running. If you find out any is good to know that there are hot fixes available.
Thanks.
Excellent, that made the trick. I also had changed the AutoPostBackFlags already.
It seems that I'm using version 10.2 see this:
Register
="Infragistics35.Web.v10.2, Version=10.2.20102.1011,
Do I still need to install the service pack?
Thank you so much for your help.
John
