Good day, newbie here asking for help.
I've been creating a comparison chart by using Visual Studio 2012 and C#.
The function required is to able to compare two megabytes size csv-based source files, display information within in table form which I'd make use of two datagridview, namely datagridview1 and datagridview2.
As the tool is dealing with time-related source, the user request had been updated to include the capability to re-select first row from both tables, in order to re-align the first signals captured which might, and most of the time, occurred on different time.
Test code 1
private void realigndataGridView1_MouseDown(object sender, MouseEventArgs e)
{
int count = 0;
if (dataGridView1.Rows.Count > 1)
{
if (dataGridView1.Rows[dataGridView1.CurrentRow.Index].IsNewRow != true)
{
do
{
dataGridView1.Rows.Remove(dataGridView1.Rows[count]);
count ++;
} while (dataGridView1.Rows[count].Index < dataGridView1.Rows[dataGridView1.CurrentRow.Index].Index);
}
}
}
Test code 2
private void btnDelete_Click(object sender, EventArgs e)
{
delete_DGV1_selectedrows();
delete_DGV2_selectedrows();
}
private void delete_DGV1_selectedrows()
{
List<DataGridViewRow> selectedRows = new List<DataGridViewRow>();
foreach (DataGridViewRow row_i1 in dataGridView1.SelectedRows)
selectedRows.Add(row_i1);
//now delete rows:
foreach (DataGridViewRow row_i1 in selectedRows)
dataGridView1.Rows.Remove(row_i1);
}
private void delete_DGV2_selectedrows()
{
List<DataGridViewRow> selectedRows = new List<DataGridViewRow>();
foreach (DataGridViewRow row_i2 in dataGridView2.SelectedRows)
selectedRows.Add(row_i2);
foreach (DataGridViewRow row_i2 in selectedRows)
dataGridView2.Rows.Remove(row_i2);
}
I'd tried to utilize the idea to delete previous rows before selected row, as shown above. But to avoid deleting useful rows accidentally, an undo function is currently under development.
//=======================================================================//
I need some advice on changing the displays solely on datagridview charts but the modification shall not involved the BindingSource.datasource(s) engaged with.
I took Beyond Compare as benchmark but it's very hard for me to create such feature now.
