Selecting Rows and Cells Programmatically
Selecting a single row
You can select a single row programmatically by setting its IsSelected property to true:
radGridView1.Rows[2].IsSelected = true;
RadGridView1.Rows(2).IsSelected = True
You can also select a single row by making it current:
radGridView1.Rows[2].IsCurrent = true;
RadGridView1.Rows(2).IsCurrent = True
Both ways of selecting a single row will result in adding this row into the RadGridView.SelectedRows collection.
Selecting multiple rows
You can select multiple rows programmatically by setting their IsSelected property to true:
radGridView1.ClearSelection();
radGridView1.MultiSelect = true;
radGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.FullRowSelect;
radGridView1.Rows[0].IsSelected = true;
radGridView1.Rows[4].IsSelected = true;
radGridView1.Rows[6].IsSelected = true;
radGridView1.Rows[9].IsSelected = true;
RadGridView1.ClearSelection()
RadGridView1.MultiSelect = True
RadGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.FullRowSelect
RadGridView1.Rows(0).IsSelected = True
RadGridView1.Rows(4).IsSelected = True
RadGridView1.Rows(6).IsSelected = True
RadGridView1.Rows(9).IsSelected = True
In this scenario all four rows are added to the SelectedRows collection of RadGridView. You can access the instances of the selected rows in the SelectedRows collection by index:
GridViewRowInfo selectedRow = radGridView1.SelectedRows[0];
Dim selectedRow As GridViewRowInfo = RadGridView1.SelectedRows(0)
The rows are added to the SelectedRows collection in the same order as the order in which you have set the selected rows.
Selecting a single cell
You can select cells the same way you select rows – by setting their IsSelected property to true:
radGridView1.ClearSelection();
radGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect;
//here instead of a cell index you can specify the Name of the column as a string
//i.e. radGridView1.Rows[1].Cells[“Column 1”].IsSelected = true;
radGridView1.Rows[1].Cells[3].IsSelected = true;
RadGridView1.ClearSelection()
RadGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect
'here instead of a cell index you can specify the Name of the column as a string
'i.e. radGridView1.Rows(1).Cells(“Column 1”).IsSelected = true
RadGridView1.Rows(1).Cells(3).IsSelected = True
Selecting a single cell will result in adding this cell into the RadGridView.SelectedCells collection.
Selecting multiple cells
Selecting multiple cells programmatically is achieved by setting the IsSelected property of the desired cells to true.
radGridView1.MultiSelect = true;
radGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect;
radGridView1.Rows[0].Cells[0].IsSelected = true;
radGridView1.Rows[3].Cells[1].IsSelected = true;
radGridView1.Rows[5].Cells[2].IsSelected = true;
radGridView1.Rows[6].Cells[3].IsSelected = true;
RadGridView1.MultiSelect = True
RadGridView1.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect
RadGridView1.Rows(0).Cells(0).IsSelected = True
RadGridView1.Rows(3).Cells(1).IsSelected = True
RadGridView1.Rows(5).Cells(2).IsSelected = True
RadGridView1.Rows(6).Cells(3).IsSelected = True
In this scenario all four cells will be added to the SelectedCells collection of RadGridView. You can access the instances of the selected cells in the SelectedCells collection by index:
GridViewCellInfo selectedCell = radGridView1.SelectedCells[0];
Dim selectedCell As GridViewCellInfo = RadGridView1.SelectedCells(0)
Note that the cells are added to the collection in the same order as the order in which you have set the selected cells.
BaseGridNavigator's Selection API
BaseGridNavigator provides a suitable API for selecting rows and columns programmatically. It can be accessed by the RadGridView.GridNavigator property. The following table lists the available public methods:
| Method | Description |
|---|---|
| SelectAll | Select all rows and cells. |
| ClearSelection | Clears the selection. |
| BeginSelection | Begins grid selection. |
| EndSelection | Ends selection. |
| Select(GridViewRowInfo row, GridViewColumn column) | Selects the sepcified row as current and specified column as current. |
| SelectFirstRow | Selects the first row as current column in grid. The method returns true if the operation is successful. |
| SelectLastRow | Selects the last row as current row in grid. The method returns true if the operation is successful. |
| SelectRow(GridViewRowInfo row) | Selects the specified row as current row in grid. The method returns true if the operation is successful. |
| SelectNextRow(int step) | Selects the row at specified distance after the current position as current row in grid. The method returns true if the operation is successful. |
| SelectPreviousRow(int step) | Selects the row at specified distance before the current position as current row in grid. The method returns true if the operation is successful. |
