AllowSelection based on Col

[Philip Bishop]

I have a grid control with 2 cols. The first col is full of drop downs. The second col is original text boxes. I want the user to be able to select multiple rows/col header in col2. In Col1 I only want the user to be able to select one cell at a time. I know how to change the allowselection property for the whole grid but I can't seem to figure how to set that for just one col. So how can I set col2 to allow basically any selection and col1 to only click one cell at a time.

Thanks.

Phil

Hi Philip,

Thank you for your interest in Syncfusion products.

To customize the selection of a GridControl based on columns, you can make use of Selections.Add() method under the SelectionChanged event to handle it.

        public Form1()
        {
            InitializeComponent();

            // other codes ...

            this.gridControl1.SelectionChanged += new Syncfusion.Windows.Forms.Grid.GridSelectionChangedEventHandler(gridControl1_SelectionChanged);
        }

        void gridControl1_SelectionChanged(object sender, Syncfusion.Windows.Forms.Grid.GridSelectionChangedEventArgs e)
        {
                if (e.Range.Top > 0 && e.Range.Left == 0) // condition for row wise selection
                {
                    this.gridControl1.Selections.Clear();
   //code to make our custom selection
                    this.gridControl1.Selections.Add(GridRangeInfo.Cells(e.Range.Top, 2, e.Range.Bottom, 2));
                }
                if (e.Range.Left == 1) // check if the selection made in first column
                {
                    this.gridControl1.Selections.Clear(); // clear all the selections.
                }
        }

Please refer the following sample which illustrates the above.
