How will I drag and drop GroupViewItem into any other control (ListView control) ?

Platform: WinForms |
Control: GroupView |

You can handle the GroupView's DragOver Event to get the selected groupviewitem and then to handle the ListView control's Drag Enter and Drag Drop events to drop the selected groupviewitem as a listviewitem in listview control

Here is the code snippet

C#

private String str = String.Empty;

private int imageIndex = -1;

private void groupView1_DragOver(object sender, System.Windows.Forms.DragEventArgs e)

{

if(e.Data.GetDataPresent(Syncfusion.Windows.Forms.Tools.GroupView.GroupViewFormatName))

{

if(this.radioButton1.Checked)

e.Effect = DragDropEffects.Move;

else

e.Effect = DragDropEffects.Copy;

GroupViewItem gbItem = e.Data.GetData(Syncfusion.Windows.Forms.Tools.GroupView.GroupViewFormatName) as GroupViewItem; str = gbItem.Text; imageIndex = gbItem.ImageIndex;

}

else

e.Effect = DragDropEffects.None;

}

private void listView1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)

{

if(e.Data.GetDataPresent(Syncfusion.Windows.Forms.Tools.GroupView.GroupViewFormatName))

{

if(this.radioButton1.Checked)

e.Effect = DragDropEffects.Move;

else

e.Effect = DragDropEffects.Copy;

}

else

e.Effect = DragDropEffects.None;

}

private void listView1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)

{

ListViewItem item = new ListViewItem(str);

item.ImageIndex = imageIndex;

this.listView1.Items.Add(item);

}
