ComboBox customization
To show the
ComboBox dropdown on entering the text in cell, TableControlCurrentCellKeyPress event
can be used and CurrentCell.ShowDropDown property can be used
in that event. The Autocomplete option can be enabled by using AutoCompleteInEditMode property.
C#
//Assigning the column cell types as GridListControl
this.gridGroupingControl1.TableDescriptor.Columns["Description"].Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.GridListControl;
//Enables Autocomplete
this.gridGroupingControl1.TableDescriptor.Columns["Description"].Appearance.AnyRecordFieldCell.AutoCompleteInEditMode = GridComboSelectionOptions.AutoSuggest;
//Triggering Event
this.gridGroupingControl1.TableControlCurrentCellKeyPress += gridGroupingControl1_TableControlCurrentCellKeyPress;
//Handling Event
void gridGroupingControl1_TableControlCurrentCellKeyPress(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlKeyPressEventArgs e)
{
if (!e.TableControl.CurrentCell.IsDroppedDown)
{
e.TableControl.CurrentCell.ShowDropDown();
}
}VB
'Assigning the column cell types as GridListControl.
Private Me.gridGroupingControl1.TableDescriptor.Columns("Description").Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.GridListControl
'Enables Autocomplete
Private Me.gridGroupingControl1.TableDescriptor.Columns("Description").Appearance.AnyRecordFieldCell.AutoCompleteInEditMode = GridComboSelectionOptions.AutoSuggest
