Insert data on column editing

[Jagan k]

hi ,

i am using RadGridView and GridViewDataColumn. i need to insert some data in to the cell while the cell is in editing mode.
for example i am having a com port which read data from the weighing machine and it has to be displayed in the cell when the user press a key (say F4) on edit mode.
i diaplying the weighing scale value in label control but not in the RadGridView.

Hello Jagan k,

If you want to change the value of the cell in edit mode once a particular key is pressed, you may handle the PreviewKeyDownEvent for example and make sure that the pressed key is the one you want. Afterwards you may change the value of the item using the corresponding property of that column:

this.playersGrid.PreviewKeyDown += new KeyEventHandler(playersGrid_PreviewKeyDown);

void playersGrid_PreviewKeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.F4)
    {
        var currentCell = this.playersGrid.CurrentCell as GridViewCell;
        if (currentCell.IsInEditMode)
        {
            var property = currentCell.DataColumn.DataMemberBinding.Path.Path;
            var editedItem = currentCell.ParentRow.Item as Player;
            var objectType = typeof(Player);
          objectType.GetProperty(property).SetValue(editedItem, "NewValue", null);
        }
    }
}

In this case the "NewValue" is the value you want to insert in that particular cell.
