this is implementation of WxButton1click, and its work fine

void maydialogDlg::WxButton1Click(wxCommandEvent& event)
{
    int SellectedRow;
    wxString Message;
    SellectedRow = MyTable->GetGridCursorRow();
    Message = "Selected Row : ";Message<<SellectedRow;
    wxMessageBox(Message);
    MyTable->SetCellValue(SellectedRow,0,WxEdit1->GetLineText(1));
    MyTable->SetCellValue(SellectedRow,1,WxEdit2->GetLineText(1));
    MyTable->SelectRow(SellectedRow++);
    MyTable->SetGridCursor(SellectedRow++,1);
    WxEdit1->Clear(); WxEdit2->Clear();
	WxEdit1->SetFocus();
}

im stuck with this

void maydialogDlg::MyTableSelectCell(wxGridEvent& event)
{
   int selected = MyTable->GetSelectedRows()[0];
   wxString data; data<<selected;

}

it says that GetSelectedRows is wxArrayInt, but int selected = MyTable->GetSelectedRows()[0]; cause an Error;

As you say GetSelectedRows returns a wxArrayInt - so you should not be using a plain int.
Given that we will get an array of integers of which rows are selected then I think you should
loop through the rows and get the cell values for each rows into the data string ( I dont see a wx function to get the whole row data in one go)

So your function might look something like this.

void maydialogDlg::MyTableSelectCell(wxGridEvent& event)
{
   wxString data;
   
   wxArrayInt rowsSelected = MyTable->GetSelectedRows();
   for (size_t rowCount =0; rowCount < rowsSelected.getCount(); rowCount++)
   {
        for (int colCount =0; colCount < myTable->GetNumberCols(); colCount++)
        {
            //get the data for each cell in the row
            data << myTable->GetCellValue(rowCount, colCount) << "  ";
        }
        data << "\n"; //add a new line to end of each row data.
    }
            
    //Do what you want with the data string
}



I'm not an expert on wxwidgets though.

You took a long time.

And your answer is not very helpful.
What doesn't work??
What's your code now??

Come on - if you want help make yourself useful.

I only use wxWidgets to make dialog boxes but since I don't like the coding style, I just design the dialog box and rob/steal (^_^) the co-ordinates of the controls and implement it in my own code, lol.
