I am using SQLite to store the data for my application. The application has a UI that loads the data from the SQLite database to display it table by table to the user. Basically the user can click left or right and view the other tables one by one.
The user can also click a button that will show a print preview of the data and let them print it. I have this working, but I am having some issues devising a dynamic way to display ANY table on the print preview screen perfectly. My concerns are if some column titles are too long etc, basically how to calculate the size of each column etc. Should I loop through and find the max character size of any text in the entire column and then set the column width to just wider than that or is there an easier way to do this?
I also write the data-table to a comma separated csv file so it might be a better alternative to use an existing solution to print from a csv file if any of you know such a solution then please suggest it!
Anyway here is the currently existing code:
// ------------------------ code that gets called when the print button is clicked ----------------------------
// holds the row data
List<string[]> myList = new List<string[]>();
if(ReportPage == 1)
{
int rowCount = MyTestTable.RowCount;
for(int i = 0; i <rowCount; i++)
{
MyTestTable.SelectedRowIndex = i;
var row1 = MyTestTable.GetSelectedRow();
var cols1 = row1.ItemArray;
string Col1 = cols1[row1.FindIndexOfColumn("Col1")].ToString();
string Col2 = cols1[row1.FindIndexOfColumn("Col2")].ToString();
string Col3 = cols1[row1.FindIndexOfColumn("Col3")].ToString();
string Col4 = cols1[row1.FindIndexOfColumn("Col4")].ToString();
string Col5 = cols1[row1.FindIndexOfColumn("Col5")].ToString();
string Col6 = cols1[row1.FindIndexOfColumn("Col6")].ToString();
string Col7 = cols1[row1.FindIndexOfColumn("Col7")].ToString();
myList.Add(new string[] { Col1, Col2, Col3, Col4, Col5, Col6, Col7 });
}
string[] cols = new string[7];
cols[0] = "Col1";
cols[1] = "Col2";
cols[2] = "Col3";
cols[3] = "Col4";
cols[4] = "Col5";
cols[5] = "Col6";
cols[6] = "Col7";
