Hello Derek, Hello unforgettable

StrToInt64 converts the string S to a Int64 value, and returns this value.
The string can only contain numerical characters, and optionally a minus sign as the first character. Whitespace is not allowed.

Hexadecimal values (starting with the $ character) are supported.
For example, IntegerString such as '123' into an Int64 return value.

It supports +ve and -ve numbers, and hexadecimal numbers, as prefixed by $ or 0x.

Thank you derek. That is what I want but you can explain strtoint64 in this statement?

procedure Form1_Edit1_OnChange (Sender: TObject);
begin
if form1.edit1.Value > 0 then form1.tablegrid1.FixedCols := strtoint64(form1.edit1.text) else form1.tablegrid1.FixedCols := 0;
end;

Hi,
You can fix columns from the left of the tablegrid if that's what you mean.
Have a look at the example where you can choose the number of columns you want to fix.
Derek.

Hi every one,
On tablegrid if we move horizontal scroll bar then columns move also. Is there a way where any selected column does not move while moving horizontal scroll bar.
