Binding 10K + elements to a dropdown list with selection

Hi Geeks,

I am having a dropdown in asp.net like -

"SelectionGrid" Visible="false" runat="server" SelectionMode="Multiple" Width="350px"
MultiTextSeparator=";" EnableFocusedStyle="false" GridViewProperties-Settings-ShowVerticalScrollBar="true"
AllowUserInput="true" GridViewProperties-SettingsPager-Mode="ShowPager" GridViewProperties-SettingsPager-PageSize="50" IncrementalFilteringMode="None"
TextFormatString="{0}" KeyFieldName="Key" IncrementalFilteringDelay="1200" GridViewProperties-Settings-ShowFilterRowMenu="true"
FocusedStyle-ForeColor="Black" GridViewProperties-Settings-ShowFilterRow="true" ClientSideEvents-KeyUp="function (s, e) {return false;}"
AutoPostBack="false" GridViewProperties-EnableCallBacks="true">
"True" Width="60px" HeaderStyle-Cursor="auto"
Caption="Select" />
"Vint" Width="200px" Visible="True" Settings-AllowSort="False"
Settings-ShowFilterRowMenu="True" Settings-ShowInFilterControl="True" Settings-AllowAutoFilterTextInputTimer="True"
Settings-AllowAutoFilter="True" FieldName="Value" Settings-AutoFilterCondition="Contains"
CellStyle-ForeColor="Black" CellStyle-Font-Bold="false" Settings-FilterMode="DisplayText">

My dropdown gets hanged when the items get loaded on the click of dropdown.

Can you please suggest some method/improvements so that the dropdown shows loading on click of dropdown till the items get loaded in the dropdown.

some code will be helpful.

thanks,

Hi Nilesh,

The dropdown has the pagination after 50 elements. User is going to select/unselect all the details based on the requirement.

Thanks,

Will it be user friendly at all if you show 10K + selections in a drop down? How the user is going to find the one of her choice?

Can't you add some more filters on top of this dropdown so that the scope of selection is limited/reduced somewhat?
