Scrolling disables cell edit When our grid has enough data to scroll through, scrolling quickly will cause the grid to disable editing (dhtmlxTreeGrid_pro_v16_80512). Example: I scroll by dragging the scroll bar with my mouse. I see that the data is refreshed (white on grid area, followed by data refresh) I click on a cell (or press F2) but the clicked cell no longer turns color (selected) or opens for editing. Is this an implementation problem or a software bug?

The only way to break row selection functionality ( such as in your case ) - use non-unique IDs in the grid. If loaded data is correct and has unique IDs, but issue still occurs - please provide js snippet of initialization code, used in problematic case.

To set background-color for the cell in the edit mode you can do the following: mygrid.attachEvent("onEditCell",function(stage,rowId,cellIndex){ if (stage==1){// if cell's editor is open this.editor.obj.style.backgroundColor="red"; } return true; }) Or you can implement custom eXcell type.

The only way to break row selection functionality ( such as in your case ) - use non-unique IDs in the grid. Please look at the attached code from my earlier post. If you execute the code and scroll through the large data sample, editing a cell is no longer possible. I am not worried about changing the color of the cell. Why is cell editing "broken" after I have scrolled enough to require a data refresh? |
