Disable Hottrack for ValueList columns
posted

Hi,

I use UltraGrid in virtual mode. I wanted to disable hottrack feature on cells, so I set CellHottrackInvalidationStyle to CellHottrackInvalidationStyle.Never.

_grid.DisplayLayout.CellHottrackInvalidationStyle = CellHottrackInvalidationStyle.Never;

Everything worked as I expected.

However, when I loaded an isl file (Office2010Black.isl or Office2010Silver.isl) by using StyleManager.Load, hottracking was unexpectedly enabled for ValueList columns. Here is the code I setup a value list to a column:

private void SetDropdownValueList(IFieldInfo fieldInfo, UltraGridColumn column)
{
    var valueList = new BindableValueList
    {
        BindingContextControl = GridControl,
        DataSource = fieldInfo.DropdownValueList.ValueList
    };
    if (!string.IsNullOrEmpty(fieldInfo.DropdownValueList.ValueMember))
        valueList.ValueMember = fieldInfo.DropdownValueList.ValueMember;
    if (!string.IsNullOrEmpty(fieldInfo.DropdownValueList.DisplayMember))
        valueList.DisplayMember = fieldInfo.DropdownValueList.DisplayMember;
    column.ValueList = valueList;
    column.Style = ColumnStyle.DropDownList;
}

Could someone help me to solve this issue please?

Thanks,
Shaolin
