Question

I have implemented a TcxGrid with some columns. The cells in the last column in this grid contains buttons of type TcxEditButton.

电网的内容要么由用户输入,要么在创建母体时从文字档案中填入。

I would like to hide some of these buttons based on a value in the grid. The value that determines the visibility of the buttons can either be read from the grids memory data set, or directly from a hidden column in the grid.

My problem is that I have not been able to find the correct event to do the check on the value, and set the buttons visibility property. I ve tried to use all sort of events both on the grids table and the column that contains the buttons.

关于如何获取纽芬兰语项目的任何建议,同时在电网被抽出时能够确定这一点?

Solution: Ended up using a modified version if the accepted solution.

procedure TFrame_cx_Element_Inntasting_Kriterier.cxGrid_InntastingDBTVPropertiesGetProperties(
  Sender: TcxCustomGridTableItem; ARecord: TcxCustomGridRecord;
  var AProperties: TcxCustomEditProperties);
begin
  if ARecord.Values[cxGrid_ColumnWithValidatedValue.Index] = true then
    AProperties := cxEditRepository1ButtonItem1.Properties
  else
    AProperties := cxEditRepository1Label1.Properties;
end;

Answer 1

使用TcxEditButton的“OnGetProperties”栏。

凭记录,可以按照一栏索引获得同一行的另一栏数值。

确定这些财产的最容易的方法是,在TcxEdit 保存地使用两个预先确定的TcxEditButtons,例如,名称为ButtonsVisible和ButtonsInvisible。

本次活动要看这样的情况:

procedure TForm1.cxGrid1TableView1EditButtonColumnGetProperties(
  Sender: TcxCustomGridTableItem; ARecord: TcxCustomGridRecord;
  var AProperties: TcxCustomEditProperties);
var
  Value: Variant;
  Buttons: TcxEditButtons;
  ButtonEnabled : Boolean;
begin
  if VarIsNull(ARecord.Values[cxGrid1TableView1ColumnToCheck.Index]) then
    AProperties := ButtonsInvisible.Properties; 
    // or AProperties := ButtonsVisible.Properties depending on what you want/need

  Value := ARecord.Values[cxGrid1TableView1ColumnToCheck.Index];
   if (Value = ValueWhenVisible) then
     AProperties := ButtonsVisible.Properties
   else
     AProperties := ButtonsInvisible.Properties;
end;

希望能让你们走上正轨。
