Nested table display settings

[Administrator]

Hi all,

Could anyone indicate how to do the following please?

1) Hide the asterisk row in the nested grids
2) Autoexpand all grids (m_historic.NestedTableGroupOptions.IsExpandedInitialValue = true doesn't seem sufficient)
3) Prevent the collapse of the nested grids (i.e they are always visible - we should probably hide the plus/minus button too in the parent grid under the primary key)

Thanks in advance,

Henry

By the way, this is a GridGroupingControl.

4) I also need to change the background colour in the area of the control that is NOT occupied by the Grid.

I have solved problem 1, using:

m_historic.NestedTableGroupOptions.ShowAddNewRecordBeforeDetails = false;

Can anyone think how to solve the other issues, please?

Hi Henry ,

2)Autoexpand all grids (m_historic.NestedTableGroupOptions.IsExpandedInitialValue = true doesn't seem sufficient)

To turn off the autosizing of the columns when the grid is first displayed, you set this property:

gridGroupingControl1.TableOptions.ColumnsMaxLengthStrategy = GridColumnsMaxLengthStrategy.None;

The other 2 enumeration values for this property tell the grid to either size the column by inspecting all values(MaxLengthSummary) or only the first N values(FirstNRecords).

If you set the first N values enumeration, you also should set:

gridGroupingControl1.TableOptions.ColumnsMaxLengthFirstNRecords = 50;//the number of records you want checked

3)Prevent the collapse of the nested grids (i.e they are always visible - we should probably hide the plus/minus button too in the parent grid under the primary key)

There is a built-in support for hide the a single cell in a grid. If you want to hide the GroupCaption row in a grid, you need to set the ShowCaption property to false.

//For MainTable GroupCaption..
this.gridGroupingControl1.TopLevelGroupOptions.ShowCaption = false;

//For nested GroupCaption..
this.gridGroupingControl1.NestedTableGroupOptions.ShowCaption = false;

//For ChildGroupCaption.
this.gridGroupingControl1.ChildGroupOptions.ShowCaption = false;

4)I also need to change the background colour in the area of the control that is NOT occupied by the Grid.

To set the background colour for the grid, please add the code below. This resolves the problem.
Here is a code snippet.

 this.gridControl1.Properties.BackgroundColor = SystemColors.Window;
