ComboBox field not opening in one click

[DavidBS]

Hi !

I'm using SFDatagGrid with a ComboBox field and everything runs 100%.

But, to get all options open when user clicks on the field, I set the same code as mentioned in documentation, as shown below:

Me.sfDataGrid.CellRenderers.Remove("ComboBox")
Me.sfDataGrid.CellRenderers.Add("ComboBox", New GridComboBoxCellRendererExt())

Public Class GridComboBoxCellRendererExt
	Inherits GridComboBoxCellRenderer
	Protected Overrides Sub OnInitializeEditElement(ByVal column As DataColumnBase, ByVal rowColumnIndex As RowColumnIndex, ByVal uiElement As SfComboBox)
		MyBase.OnInitializeEditElement(column, rowColumnIndex, uiElement)
		uiElement.ShowDropDown()
	End Sub
End Class

But, unfortunately, the combo does not open in 1-click mode...  If I do a double-click on it, ok, the options open.

Do you know what am I doing wrong?

I appreciate in advance for any help.

Hi DavidBS,

Thank you for contacting Syncfusion support.

Your requirement can be achieved by set the SingleClick value as EditMode property in SfDataGrid. Please refer the below code snippet, 

orderInfo = new OrderInfoCollection(); 

            

this.sfDataGrid1.EditMode = EditMode.SingleClick; 

this.sfDataGrid1.DataSource = orderInfo.OrdersListDetails; 

this.sfDataGrid1.AutoSizeColumnsMode = AutoSizeColumnsMode.Fill; 

this.sfDataGrid1.Columns.Add(new GridNumericColumn() { MappingName = "OrderID", HeaderText = "Order ID"});           

 this.sfDataGrid1.Columns.Add(new GridCheckBoxColumn() { MappingName = "IsClosed", HeaderText = "Closed", AllowCheckBoxOnHeader = true, CheckBoxSize = new Size(13, 13), Width = 100 }); 

this.sfDataGrid1.Columns.Add(new GridComboBoxColumn() { MappingName = "ShipCityID", HeaderText = "Ship City", DisplayMember = "ShipCityName", ValueMember = "ShipCityID", DropDownStyle = DropDownStyle.DropDownList, DataSource = orderInfo.ShipCityDetails }); 

this.sfDataGrid1.Columns.Add(new GridMultiSelectComboBoxColumn() { MappingName = "Products", HeaderText = "Products", DisplayMember = "ProductName", ValueMember = "ProductName", DataSource = orderInfo.ProductDetails }); 

 

this.sfDataGrid1.CellRenderers.Remove("ComboBox"); 

this.sfDataGrid1.CellRenderers.Add("ComboBox", new GridComboBoxCellRendererExt());
