Help adding Tbutton to DBGrid please

[BuilderSpec]

Hi

Hoping someone can help.

Using C++ builder 6

New Project , add a TButton called Button1 , a DBGrid and associate some data to it. Mine has at least 3 columns of data.

Want the end result to be that in the 3rd column I want a button to display.

I have got this so far :

void __fastcall TForm1:BGrid1DrawColumnCell(TObject *Sender,
const TRect &Rect, int DataCol, TColumn *Column,
TGridDrawState State)
{


if ( Button1->Parent != DBGrid1 )
Button1->Parent = DBGrid1;

if ( Column->Index == 2 )
{
if ( State.Contains(gdFocused) )
{
if ( Button1->Left != (Rect.Right - Button1->Width ) )
Button1->Left = Rect.Right - Button1->Width ;
if ( Button1->Top != Rect.Top )
Button1->Top = Rect.Top;
if ( Button1->Height != ( Rect.Bottom - Rect.Top ) )
Button1->Height = Rect.Bottom - Rect.Top ;
Button1->Visible = true;
}
}
}


Only issue is that it only shows the button if I am on that record and would like it to show the button on all records. The above only shows the button per line if i click into column 3. Would like the button to show regardless if possible for all rows. But at the least to show button when i enter the record regardless of column.

Any ideas please ?

Graham

Hope this helps!

Good day, Graham

I didn't fully understand your question. Do you want to show this button in all your records in column 3 simultaneously? Or do you simply want this button to be shown in column 3 regardless of the column you chose?

The first variant seems to me impossible, because I can't understand, how one object can be placed in many cells simultaneously. And if you want the second variant, you simply can change your code of DBGrid1DrawColumnCell() function to this one:

if ( Button1->Parent != DBGrid1 )
Button1->Parent = DBGrid1;
if ( State.Contains(gdFocused) ) {
int leftB = DBGrid1->Columns->Items[0]->Width + DBGrid1->Columns->Items[1]->Width + DBGrid1->Columns->Items[2]->Width + 15;
if ( Button1->Left != leftB - Button1->Width )
Button1->Left = leftB - Button1->Width ;
if ( Button1->Top != Rect.Top )
Button1->Top = Rect.Top;
if ( Button1->Height != ( Rect.Bottom - Rect.Top ) )
Button1->Height = Rect.Bottom - Rect.Top ;
Button1->Visible = true;
}

Or maybe I just didn't understand you correctly

Hope, it will help you
