Hi All,

I want to lock some of excel cells (not all) using C#.
When someone opens the excel file, they will be able to edit any cell except those cells. And if someone wishes to delete all editable data then read-only cells will retain their value and other editable cells will lose their value. Also the workbook should not have password.

I tried to lock cells like this:

C#

wsht.Cells[rowcnt, colcnt].Locked = true;

Tried locking range in similar way. But they won't work. Protecting sheet after locking cells or range makes all cells read-only.

Anyone??

What I have tried:

Locking cells:

C#

wsht.Cells[rowcnt, colcnt].Locked = true;

Locking range:

C#

wsht.Range[wsht.Cells[rowcnt, 1], wsht.Cells[rowcnt, wordString.Length - 1]].Locked = true;

They won't work and protecting sheet after these codes makes all cells uneditable.

Protect the sheet first,

C#

wsht.Protect()

Then unprotect the cells you want to edit.

C#

wsht.Range[wsht.Cells[rowcnt, 1], wsht.Cells[rowcnt, wordString.Length - 1]].Locked = false;
