I have a RadComboBox control inside RadGrid in which Items are loaded using LoadOnDemandmechanism i.e., _ItemRequested() event
All working fine except the 2 issues:
1) There is a significant lag between the time the end-user begins typing and when the filtered items show up. What I observed that the searching in RadcomboBox is done character wise not Word wise.
2) Also, takes time to load data regardless of what value is set in ItemPerRequest property in RadComboBox when using LoadOnDemand.
The maximum items in this RadComboBox can be 20,000+ as well.
User is complaining again and again for the performance issue. Please someone let me know the simplest way of resolving the 2 issues.
I followed below Link (Server Side method), to achieve LoadOnDemand functionality:http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
If there is no solution to solve the 2 preformance issue then please let me know how to do the searching in RadComboBox, which is inside RadGrid, using LoadOnDemand approach on BUTTON click ?? Will this resolve the 1st Issue ??
Please note that I am new in Telerik. Thanks in advance.
