Hello, Ajith,
Thank you for writing back.
Here is demonstrated a sample approach how to store the initial cell values and restore them when you click the "
Reject" button:
public RadForm1()
{
InitializeComponent();
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Name", typeof(string));
for (int i = 0; i < 10; i++)
{
dt.Rows.Add(i, "Item" + i);
}
this.radGridView1.DataSource = dt;
GridViewCommandColumn commandColumn = new GridViewCommandColumn("Reject");
commandColumn.UseDefaultText = true;
commandColumn.DefaultText = "Reject";
radGridView1.MasterTemplate.Columns.Add(commandColumn);
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
this.radGridView1.CellValidating += radGridView1_CellValidating;
this.radGridView1.CommandCellClick += radGridView1_CommandCellClick;
}
private void radGridView1_CommandCellClick(object sender, GridViewCellEventArgs e)
{
foreach (GridViewCellInfo cell in e.Row.Cells)
{
if (cell.Tag!=null)
{
cell.Value = cell.Tag;
cell.Tag = null;
}
}
}
private void radGridView1_CellValidating(object sender, CellValidatingEventArgs e)
{
if (e.ActiveEditor != null && e.Row.Cells[e.Column.Name].Tag == null)
{
//store the initial value
e.Row.Cells[e.Column.Name].Tag = e.Row.Cells[e.Column.Name].Value;
}
}
The attached gif file illustrates the implemented behavior. Note that this is just a sample approach and it may not cover all possible cases. Feel free to modify it in a way which suits your requirement best.
I hope this information helps. If you have any additional questions, please let me know.
Regards,
