Empty GridViewDataColumn cause major lag while scrolling/filtering?

[Joachim Karlsson]

Hey,

Was labbing some this morning and i come over this.

   <telerik:GridViewDataColumn Header="LogistikID" DataMemberBinding="{Binding nOrderID}" />
   <telerik:GridViewDataColumn Header="Namn" DataMemberBinding="{Binding strDisplayName}"/>
   <telerik:GridViewDataColumn Header="CareOf" DataMemberBinding="{Binding strCareOf}"/>
   <telerik:GridViewDataColumn Header="Gata" DataMemberBinding="{Binding strAddress}"/>
   <telerik:GridViewDataColumn Header="" />


If i leave one column not binded the Gridview lags like hell.

Im pretty sure i have to bind them all because i use GridViewDataColumn, but is it realy gonna lag so bad?

If i leave it empty, Shouldn't it just be ignored?

If i bind the last GridViewDataColumn it's lag free while scrolling/filtering.

Bug or Feature?

Hello,

What is business scenario of having an unbound GridViewDataColumn? Can you provide an example?

Theres no reason to have it,
I added an empty column for future use, I just left it empty while testing something
and i couldn't figure out while it was lagging so much while filtering/scrolling, So im just saying.

But why is it lagging with an empty column and not with a binded one?

Hi,

We will investigate this lagging.

Meanwhile, you can workaround the lag by not having an unbound column.

Thank you for your understanding.
