hi i got a question related to the datagridview cellvalue and celleditedformatedvalue. What i want to do is
i try key in the product code to my first column by keyboard at first - this works fine cos is in edit mode and the value is null. However when i change the product code again by using F2, what trouble me is the EditedFormattedValue which i key in at first by keyboard is still there. As such, it enters into the both" if statement" below:
How can i prevent it by clearing the editedformattedvalue?
private void Form1_Load(object sender, EventArgs e)
{
this.dataGridView1.Columns.Add("c1", "c1");
this.dataGridView1.Columns.Add("c2", "c2");
this.dataGridView1.Rows.Add();
this.dataGridView1.CellValidating +=
new DataGridViewCellValidatingEventHandler(dataGridView1_CellValidating);
}
void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
if (e.ColumnIndex == 0)
{
if(this.dataGridView1.CurrentCell.EditedFormattedValue!=null)
{
Console.WriteLine("CurrentCell.EditedFormattedValue" + this.dataGridView1.CurrentCell.EditedFormattedValue.ToString());
}
if (this.dataGridView1.CurrentCell.Value != null)
{
Console.WriteLine("CurrentCell.Value " + this.dataGridView1.CurrentCell.Value.ToString());
}
Console.WriteLine("");
}
}
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.F2)
{
Form2 f = new Form2();
f.ShowDialog();
this.dataGridView1.CurrentCell.Value = f.Code;
}
return base.ProcessCmdKey(ref msg, keyData);
}
