grid selecting multiple rows

[Smitha]

Hi,

I want to be able to do a delete on multiple rows for the grid control. I am using windows forms, C#

I have a grid with a context menu
On right click, the user can choose to add, delete.

He could select some rows and choose to delete all at once.

How do I enable selection of multiple rows. and then delete
What events should I use.

Thanks
Smitha

Hi Smitha,

Thanks for your interest in Syncfusion products.

To select multiple rows, set the "ListBoxselectionMode" to "MultiExtended".

this.gridControl1.ListBoxSelectionMode = SelectionMode.MultiExtended;

You can handle "contextMenuStrip1.ItemClicked" to check if the menu option selected is "Delete" to delete the rows from the grid.

 void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
        {
            if (e.ClickedItem.Text == "Delete")
            {
                if (this.gridControl1.Selections.Count > 0)
                {
                    GridRangeInfoList ranges = this.gridControl1.Selections.Ranges;
                    foreach (GridRangeInfo r in ranges)
                    {
                        this.gridControl1.Rows.RemoveRange(r.Top, r.Bottom);
                    }
                }
            }
        }

Hi Mercy,

What is the difference between
theGrid.Model.Options.SelectCellsMouseButtonsMask = MouseButtons.Left;
this.theGrid.AllowSelection = Syncfusion.Windows.Forms.Grid.GridSelectionFlags.Any;

and

theGrid.ListBoxSelectionMode = SelectionMode.MultiExtended;

Thanks

You can have context menu on right click on column headers by using ‘TableControlCellClick’ event along with the following code. Please refer the following code to achieve the behavior.
