Scroll +Static Headers + GridEditMode.EditForms

[Lasly]

HI,
I have a  RadGrid , the RadGrid has  scrolling enabled and UseStaticHeaders=True.
When UseStaticHeaders is True, the header row is still visible, even when the grid is scrolled. (perfect)

But  When I generated ItemCommand "initinsert"  with GridEditMode.EditForms  don't works (image 1) [problem]
       When I generated ItemCommand "edit"  with GridEditMode.EditForms  it works (image 2)

grdANAAGG.MasterTableView.EditMode = GridEditMode.EditForms;
grdANAAGG.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top;
grdANAAGG.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = true;
grdANAAGG.MasterTableView.PagerStyle.Mode = GridPagerMode.NumericPages;
grdANAAGG.ClientSettings.Scrolling.AllowScroll = true;
grdANAAGG.ClientSettings.Scrolling.EnableVirtualScrollPaging = true;
grdANAAGG.ClientSettings.Scrolling.UseStaticHeaders = true;
grdANAAGG.ClientSettings.Scrolling.SaveScrollPosition = true;

thank you very much

P.S.
without  "ClientSettings.Scrolling.UseStaticHeaders = true;" always works.

Hello,

Indeed the described behaviour can be observed, because when static headers are enabled for the grid ClientSettings.Scrolling.ScrollHeight property is set to 300px by default for the MasterTableView. Therefore, when you open EditForm vertical scrollbar appear. Other than this when you open InsertForm the grid is automatically resized to fit the content. This is so, because grid InsertForm is positioned outside the mastertableview( inside header or pager).

However,  one possible solution for your case is to set Height property of the grid to some fixed value as demonstrated in the attached project. Give it a try and see if its useful for you. Another option is to set EditMode property to InPlace or disable static headers(set UseStaticHeaders to false).

For more information about height vs ScrollHeight you can refer to the help article below.

Thanks for the reply.
The  solution for our case is  disable static headers when the ItemCommand  is initinsert.

Hello,
I thought I had solved the problems with static columns. disable static headers when the ItemCommand  is initinsert.
But if I disable the static columns in a form where are  firing the required file validator  I get the Ajax exception:
"Sys.WebForms.PageRequestManagerServerErrorException: Exception thrown by the target of a call."
(I add the required file validator all'item_created.)

thanks
