We are using a wrapper to set certain default behavior for the RadGridView.

While debugging a feature we disabled that was not working it appears that the grid.MasterTemplate.EndInit() method is resetting some properties back to their default.

We have also overriden the MasterGridViewTemplate per this article: (http://www.telerik.com/forums/question-about-mastergridviewtemplate-and-mastertemplate).

Current Issue and solution we have implemented:

Some properties (namely EnableHotTracking) that we set in the MasterTemplateGridViewElement override, or the GridView wrapper are getting reset to their defaults.  (Even some properties that are set from the designer are getting reset back to their defaults)

Our work around now is to override the EndInit() method and inside, after base.EndInit(), we re-set the properties there were not holding their value.

Is there a different way to do this?  Are we missing something?

Hi,

does the ChartView support huge amounts of data? I found using ~220k datapoints as a source for various barseries' takes a really long time. In essence the chart uses a linear vertical axis and a datetimecategorial axis to sort the data and all datapoints are visualized by barseries' which may be stacked. Is there a way to optimize performance and setup time of charts? Please note I am using RadChartElements, so I cannot access the full functionality of RadChartViews.

This issue can be seen in the Telerik Demo Application - UI for WinForms.  In the list at the left, select "DropDown & List".  From the DropDownList group of demos, select "Auto complete" (the one with the list of countries and their flags).  When the list is first displayed the dropdown list is opened and focus is in the keyin field.  Key in the letter 'C'.  You will see the list of countries that begin with 'C' over the original list of all countries.  See the attached image.

Is this a defect?  Is there a way to work around the issue?
