Is there a way to take the Text of an specific cell from a TString?

How do I take the text of an specific cell on a TStringGrid to store it in a variable?

Cells [ x,y ]

MyString := Cells [ Column, Row ];

Note:

 Fixed cells are part of the indexing..

Oh Wait, you want to take that from a Tstring... Hmmm.
I think that is comma delimited but I would need to check that..

The same way you set them, but contrarywise:
Code: Pascal  [Select][+][-]
  1. MyString := MyGrid.Cells[Column, Row];

ETA: Well, Jamie beat me to it  :P

BTW, Happy new year! :D

ah that's it, Rows returns a TstringList so you could just index them as lines.


MyStringList := Grid1.Rows;

MyStringList.Strings[?] = a string of a cell.

Huh? shouldn't it be:
Code: Pascal  [Select][+][-]
  1. RowStrings := Grid1.Rows[Row];
  2. MyString := RowStrings[Column];
?

But knowing the (row,column) coordinates, I would use Grid.Cells[] directy; more intuitive.

@AfootDesert41

Here has a simple demo showing how to load data from TDbf and show it to TStringGrid, change the cells' color and doing searching by reading and comparing the cell content with a search keyword provided by user:
