Hi i'm working with Visual C# and i've a method that exports a DataGridView to an Excel File, my question is how can I give format to the Excel file so it looks better, like making the headers look bold, and coloured with blue, etc.
The method that i'm using is this:
public static void Excel(DataGridView datagridview, bool captions = true)
{
object objApp_Late;
object objBook_Late;
object objBooks_Late;
object objSheets_Late;
object objSheet_Late;
object objRange_Late;
object[] Parameters;
string[] headers = new string[datagridview.ColumnCount];
string[] columns = new string[datagridview.ColumnCount];
int i = 0;
int c = 0;
for (c = 0; c < datagridview.ColumnCount; c++)
{
headers[c] = datagridview.Rows[0].Cells[c].OwningColumn.Name.ToString();
i = c + 65;
columns[c] = Convert.ToString((char)i);
}
try
{
Type objClassType;
objClassType = Type.GetTypeFromProgID("Excel.Application");
objApp_Late = Activator.CreateInstance(objClassType);
objBooks_Late = objApp_Late.GetType().InvokeMember("Workbooks",
BindingFlags.GetProperty, null, objApp_Late, null);
objBook_Late = objBooks_Late.GetType().InvokeMember("Add",
BindingFlags.InvokeMethod, null, objBooks_Late, null);
objSheets_Late = objBook_Late.GetType().InvokeMember("Worksheets",
BindingFlags.GetProperty, null, objBook_Late, null);
Parameters = new Object[1];
Parameters[0] = 1;
objSheet_Late = objSheets_Late.GetType().InvokeMember("Item",
BindingFlags.GetProperty, null, objSheets_Late, Parameters);
if (captions)
{
for (c = 0; c < datagridview.ColumnCount; c++)
{
Parameters = new Object[2];
Parameters[0] = columns[c] + "1";
Parameters[1] = Missing.Value;
objRange_Late = objSheet_Late.GetType().InvokeMember("Range",
BindingFlags.GetProperty, null, objSheet_Late, Parameters);
Parameters = new Object[1];
Parameters[0] = headers[c];
objRange_Late.GetType().InvokeMember("Value", BindingFlags.SetProperty,
null, objRange_Late, Parameters);
}
}
for (i = 0; i < datagridview.RowCount; i++)
{
for (c = 0; c < datagridview.ColumnCount; c++)
{
Parameters = new Object[2];
Parameters[0] = columns[c] + Convert.ToString(i + 2);
Parameters[1] = Missing.Value;
objRange_Late = objSheet_Late.GetType().InvokeMember("Range",
BindingFlags.GetProperty, null, objSheet_Late, Parameters);
Parameters = new Object[1];
Parameters[0] = datagridview.Rows[i].Cells[headers[c]].Value.ToString();
objRange_Late.GetType().InvokeMember("Value", BindingFlags.SetProperty,
null, objRange_Late, Parameters);
}
}
Parameters = new Object[1];
Parameters[0] = true;
objApp_Late.GetType().InvokeMember("Visible", BindingFlags.SetProperty,
null, objApp_Late, Parameters);
objApp_Late.GetType().InvokeMember("UserControl", BindingFlags.SetProperty,
null, objApp_Late, Parameters);
}
catch (Exception theException)
{
String errorMessage;
errorMessage = "Error: ";
String.Format("{0} {1} {2}", theException.Message, "Line:", theException.Source);
MessageBox.Show(errorMessage, "Error");
}
}
Thanks in advance.
Best Regards.
