Selecting a program in a DataGridView programmatically

Question

How can I select a specific range of rows in a DataGridView programmatically at runtime?

Answer 1

Not tested, but I think you can do the following:

 dataGrid.Rows[index].Selected = true; 

or you can do the following (but again: not verified):

 dataGrid.SelectedRows.Clear(); foreach(DataGridViewRow row in dataGrid.Rows) { if(YOUR CONDITION) row.Selected = true; } 

Answer 2

In Visual Basic, do this to select a row in a DataGridView ; the selected line will appear with highlighted color, but note that the cursor position does not change:

 Grid.Rows(0).Selected = True 

Change the cursor position:

 Grid.CurrentCell = Grid.Rows(0).Cells(0) 

The concatenation of the lines above will position the cursor and select the line. This is the standard procedure for focusing and selecting a row in a DataGridView :

 Grid.CurrentCell = Grid.Rows(0).Cells(0) Grid.Rows(0).Selected = True 

Answer 3

 DataGridView.Rows .OfType<DataGridViewRow>() .Where(x => (int)x.Cells["Id"].Value == pId) .ToArray<DataGridViewRow>()[0] .Selected = true; 

Answer 4

Try the following:

 datagridview.Rows[currentRow].Cells[0]; 

Answer 5

You can use the selection method if you have a data source: http://msdn.microsoft.com/en-us/library/b51xae2y%28v=vs.71%29.aspx

Or use linq if you have objects in your data source

Answer 6

  <GridViewName>.ClearSelection(); ----------------------------------------------------1 foreach(var item in itemList) -------------------------------------------------------2 { rowHandle =<GridViewName>.LocateByValue("UniqueProperty_Name", item.unique_id );--3 if (rowHandle != GridControl.InvalidRowHandle)------------------------------------4 { <GridViewName>.SelectRow(rowHandle);------------------------------------ -----5 } } 

• Clear all previous selection.
• Scrolling lines should be selected in your grid.
• Get your row handles from the grid (note that the grid is already updated with new rows)
• Validation of the string descriptor.
• When a valid line descriptor then select it.

If itemList is a list of rows that should be selected as a grid.
