Hi

What is the WiseJ equivalent of:

For a DataGridView

objDGV.ItemsPerPage

objDGV.TotalPages

objDGV.CurrentPage

For Custom Combo Box

GetCustomDropDown()

IsCustomDropDown

IsDelayedDrawing

this.ShowPopup(objParent, Forms.DialogAlignment.Below);

Gizmox.WebGUI.Forms.KeyPressEventHandler

Thanks

Hi

Noticed you have added a popup control. Can this be used as a custom drop down or has this yet to be implemented?

How do you use the Alignment property?

Thanks for your help

Hi Ewan,

See answers below:

  • There is no paging in Wisej. The grid uses a virtual scroller/renderer – only the visible cells are rendered to the dom. The same for the listview. Since paging is a combination of prev/next navigation and scrolling, it’s relatively easy to add a pager and populate only the page rows. ¬†You can drop a panel inside a grid and dock to bottom. We could also create a pager extension component that can be used in several contexts.
  • There is no custom dropdown control yet. It’s on the todo list.
  • IsDelayedDrawing is not relevant in Wisej.
  • There is a UserPopup or PopupPanel on the todo list that would allow you to attach an automatic popup to any control and to show/hide it programmatically.
  • The KeyDown, KeyUp, and KeyPress are all available.

Best,

Luca

Hi

Is there a custom combo box drop down option?

So you can create such things as a multicolumn combo box or a combo box with a drop down tree view both of which I use extensively?

With a multicolumn combo box you need a way of resizing the drop down height to reflect the number of searched for items together with a maximum height before the grid starts paging or scrolling if paging is not an option
