int rowNumber = 3;<br />
int cellNumber = 2;<br />
<br />
bool b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;
But one tricky thing is here: if a value you are getting was not set (nobody checks or unchecks this checkbox) the value of it is null. We need handle this case.
int rowNumber = 3;<br />
int cellNumber = 2;<br />
<br />
bool b = false;<br />
if (dataGridView1.Rows[rowNumber].Cells[cellNumber].Value != null)<br />
{<br />
b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;<br />
}<br />

You want to see if the user has a file on the local machine from an ASP web page? Can't do it, you don't have file access rights to the local machine from a web page.

ActiveX has file rights I think. Not sure, why do you need to do this from a web application.

I wouldn't thank me yet, make sure it does what you need it to. I still don't understand why you are doing that check.

iTextSharp is a library that allows you to generate PDF files on the fly.
SharpPDF is a C# library that implements different objects for the creation of PDF documents.
Are all were the inbuilt library in C#

They all are external references.
.NET itself doesn't have any support for PDF.

Thank you all i got the logic and it helped me to create the file.
if i have any further clarifications i will ask you.
Once again Thank you so much

ItexrSharp and SharpPDf are all external references only. As for us there is not inbuilt references for PDF in .Net

Hi, I am using Interop to gain access and make editions to an excel file and I am able to make it to individual cells. However I cannot seem to figure out how to make changes to an object like a textbox and checkbox programmatically using C# in the Excel file.
|
|
|
|

I assume here that you can get the Excel, Workbook and Worksheet objects...
String sFileName = <full path to file>;
Microsoft.Office.Interop.Excel.Application oApp =
new Microsoft.Office.Interop.Excel.Application();
Workbook wkb = oApp.Workbooks.Open(sFileName, .....);
Worksheet sheet1 = wkb.Worksheets["Sheet 1"] as Worksheet;
Microsoft.Office.Interop.Excel.CheckBox cb = sheet1.CheckBoxes("Check Box 101");
...the rest should be obvious. For example, cb.Value = true;
That's the code. The non-obvious part to me was the name - in this case "Check Box 101". In the upper left corner of Excel, as you click from cell to cell, it shows the name of the cell. For example, A1, A2, etc... If you RMB on the CheckBox it will show the name of the CheckBox in this very same location. You can change the name to whatever you want. That's the name you use in code to access the CheckBox from the list. Excel will auto-name them so there is some predictability. But I've received spreadsheets where the names are all over the map.
Good luck!

Wow.
You named a member variable 'i', and you incremented it. How would this get any item ?
Where is the data set ? Are you showing it's contents on screen ? where do you hope to get this data from, and to ?
