GGC: Edit the CurrentCell

[Administrator]

Hi!
In a GGC I''d like to have the following behavior:

A single click selects the hole row. A DoubleClick Starts the Editing of the doubleclicked Cell.

How can this behavior be implemented?

Hi Falk,

This can be achieved by setting the following properties.

++++++++++++++
gridGroupingControl1.TableModel.Options.ActivateCurrentCellBehavior = GridCellActivateAction.DblClickOnCell;
gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;
++++++++++++++

Ok, this works.

But now the CurrentCell (if not in EditMode) has a white Backcolor and a black Forecolor.

But as long as the CurrentCell is not in EditMode, I want it to look like the other Cells of the selected row (black BackColor and White ForeColor)

Hi Falk,

The property named ListBoxSelectionCurrentCellOptions in TableOptions, using which you can set the current cell behaviour or to have currentcell’s color to be of selection color and while editing to be white color. Please follow the code snippet.

++++++++++++++++++++
private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
if(e.TableCellIdentity.RowIndex == cc.RowIndex && e.TableCellIdentity.ColIndex == cc.ColIndex)
{
if(cc.IsEditing )
e.Style.BackColor = Color.White;
else
{
e.Style.BackColor = this.gridGroupingControl1.TableOptions.SelectionBackColor;
this.gridGroupingControl1.TableControl.RefreshRange(GridRangeInfo.Cell(cc.RowIndex,cc.ColIndex));
}
}
}
++++++++++++++++++++

Thanks,

This works fine, except for one Column: A Column with the CellType Currency.
If I set the CellType to TextBox -> it works. If I set it to Currency ->

(in Not-EditMode): Backcolor keeps in the SelectionBackColor-State and the TextColor is Black.

(in EditMode): Backcolor keeps in the SelectionBackColor-State and the TextColor is White.

Can you solve this problem?

Hi Falk,

Please try the following code snippet and let us know if this helps.

+++++++++++++++++++++++++++++
private void gridGroupingControl1_TableControlPrepareViewStyleInfo(object sender, GridTableControlPrepareViewStyleInfoEventArgs e)
{
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
if(e.Inner.RowIndex == cc.RowIndex && e.Inner.ColIndex == cc.ColIndex )
{
if(e.Inner.Style.CellType == GridCellTypeName.Currency && !cc.IsEditing)
{
e.Inner.Style.BackColor = this.gridGroupingControl1.TableOptions.SelectionBackColor;
this.gridGroupingControl1.TableControl.InvalidateRange(GridRangeInfo.Cell(cc.RowIndex,cc.ColIndex));
}
else if(cc.IsEditing )
{
e.Inner.Style.BackColor = Color.White;
}
else
{
e.Inner.Style.BackColor = this.gridGroupingControl1.TableOptions.SelectionBackColor;
this.gridGroupingControl1.TableControl.RefreshRange(GridRangeInfo.Cell(cc.RowIndex,cc.ColIndex));
}
}
}

private void TableControl_CurrentCellStartEditing(object sender, CancelEventArgs e)
{
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
if(cc.Renderer.StyleInfo.CellType == GridCellTypeName.Currency)
{
GridCurrencyTextBoxCellRenderer cr = cc.Renderer as GridCurrencyTextBoxCellRenderer;
GridCurrencyTextBox tb = cr.Control as GridCurrencyTextBox;
tb.BackColor = Color.White;
this.gridGroupingControl1.TableControl.InvalidateRange(GridRangeInfo.Cell(cc.RowIndex,cc.ColIndex));
}
}

Thanks for your patience.
