ComboBox Cell selection issue

[Basavaraj Angadi]

Hi ,

  I have a grid , in that I have a column of type Combobox.

            e.Style.CellType = "ComboBox";

            e.Style.DropDownStyle = GridDropDownStyle.AutoComplete;

            e.Style.DropdownEdit.ShowButton = false;

            e.Style.ItemsSource = items;

            grid.Model.Options.ActivateCurrentCellBehavior = GridCellActivateAction.ClickOnCell;

My requirement : If I Click (single click) On the cell , i should be able to see the ComboBox Icon In that Cell and Cursor should  not be visible.

Only the cell should be selected. , on subsequent clicks cursor can behave as normal.

I have attached the snapshot, which shows my requirement.

Please do the needful.

Hi Basavaraj,

Thank you for using Syncfusion products.
We have analyzed your requirement and you can achieve this by using PreviewMouseLeftButtonEvent and CurrentCellStartEditing Event as shown in the below code snippet.
Here we have disabled the cursor at first click in combobox column(CustomerID).

Code Snippet:

private MouseButtonEventArgs clickArgs = null;

void dataGrid_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)

{

if (e.ClickCount == 1)

clickArgs = e;

else

clickArgs = null;

}

void dataGrid_CurrentCellStartEditing(object sender, Syncfusion.Windows.ComponentModel.SyncfusionCancelRoutedEventArgs args)

{

if (clickArgs != null)

{

this.Dispatcher.BeginInvoke(new Action(SetCursor), System.Windows.Threading.DispatcherPriority.ApplicationIdle);

}

}

private void SetCursor()

{

GridCurrentCell cc = this.dataGrid.Model.CurrencyManager.CurrentCell;

if (cc.Renderer.CurrentCellUIElement is GridCellComboBoxDropDown)

{

GridCellComboBoxDropDown combo = cc.Renderer.CurrentCellUIElement as GridCellComboBoxDropDown;

combo.IsEnabled = false;

clickArgs = null;

}
}

We have prepared a sample to achieve your requirement and please find the sample from the below location,
