We could able to understand your scenario and created the simple sample as per your requirement. You can add the custom controls as you want in ComboBox DropDown by adding the controls in the GridComboBoxCellRenderer.DropDownContainer and also you can customize the dropdown width and height by using e.Inner.Size property in TableControlCurrentCellShowingDropDown event.      Code example:  void gridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellShowingDropDownEventArgs e)  {      GridComboBoxCellRenderer renderer = e.TableControl.CurrentCell.Renderer as GridComboBoxCellRenderer;           ComboBox combo = new ComboBox();      combo.DataSource = dt;      combo.DisplayMember = "Value";      combo.ValueMember = "ID";        //Remove the default control      renderer.DropDownContainer.Controls.RemoveAt(0);             //Add the GridControl in DropDown.      renderer.DropDownContainer.Controls.Add(combo);        //Change the DropDown width and Height.      e.Inner.Size = new Size(200, e.Inner.Size.Height);  }

If you want to add the custom controls (i.e GridControl,Calculator, etc.) ,please refer to the dash boards samples from below location,  

<InstalledLocation\Syncfusion\EssentialStudio\VersionNumber\Windows\Grid.Windows\Samples\Custom Cell Types\Drop Down Cell Demo\CS> 

If you want to add the GridListControl directly into ComboBox, please refer to the dash board sample from below location,

I tried to add GridlistControl but it is not woriking:

 GridComboBoxCellRenderer renderer = e.TableControl.CurrentCell.Renderer as GridComboBoxCellRenderer;

            //Remove the default control 

            renderer.DropDownContainer.Controls.RemoveAt(0);

            //Add the GridControl in DropDown. 

            renderer.DropDownContainer.Controls.Add(gridNguyenLieu);

            //Change the DropDown width and Height. 

            e.Inner.Size = new Size(200, e.Inner.Size.Height); 

I want to add this grid as same as add grid to popupcontrol of combodropdown:

           cbo_HangHoaCha.PopupControl = gridHangHoaCha;

Hi Truong, 

 

Thanks for your update. 

 

We can reproduce your scenario. By default, GridListControl size as 0 when initialize the grid. So, the size should be defined before the GridListControl initialization then only which can visible in drop down container. Please refer to the below code example and the attached sample, 

 

Code example 

GridComboBoxCellRendererrenderer = e.TableControl.CurrentCell.Renderer as GridComboBoxCellRenderer; 

             

GridListControl list = new GridListControl(); 

list.DataSource = dt; 

list.DisplayMember = "Value"; 

list.ValueMember = "ID"; 

list.Dock = DockStyle.Fill; 

//(Or) 

//list.Size = new System.Drawing.Size(100, 60); 

//Remove the default control 

renderer.DropDownContainer.Controls.RemoveAt(0); 

//Add the GridControl in DropDown. 

renderer.DropDownContainer.Controls.Add(list); 

             

e.Inner.Size = new Size(200, e.Inner.Size.Height);

Note: 

By default, GridGroupingControl having the support for GridListCotrol cell type so you can directly use this CellType for grid cells. Please refer to the below code example, 

 

Code example 

this.gridGroupingControl1.TableDescriptor.Columns["Description"].Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.GridListControl;
