Question

您好我有一个数据网格控件（不是datagridview控件）放在一个Windows窗体（Vb）它有10列。我试图在其中一个列中输入十进制值，但它正在重置其值。例如：

我在一个单元格中有31个并且在我更改单元格时尝试将其编辑为20.5，它会重置为31.如果我输入任何整数值，如21，则接受该值。

_da = New OleDbDataAdapter("SELECT EMPDETAILPERSONAL.EMPCODE, EMPDETAILPERSONAL.EMPNAME, EMPDETAILPERSONAL.EMPDEPT, EMPDETAILPERSONAL.EMPDOB, 0 AS AGE, " & _
    " EMPDETAILPERSONAL.EMPDOJ, EMPDETAILPERSONAL.EMPPANNP, " & Date.DaysInMonth(selYear, selMonth) & " AS NOD, " & Date.DaysInMonth(selYear, selMonth) & " AS LD, CSDEPT.CSDEPTNAME, EMPDETAILPERSONAL.EMPDESG, " & _
    " EMPDETAILPERSONAL.EMPSALACC, EMPDETAILPERSONAL.EMPPFACC, EMPDETAILPERSONAL.EMPPPFACC, EMPDETAILPAYROLL.EMPBASIC, EMPDETAILPAYROLL.EMPGPA, CDbl(0) AS CONS, " & _
    " EMPDETAILPAYROLL.EMPDA, EMPDETAILPAYROLL.EMPHRA, EMPDETAILPAYROLL.EMPTA, EMPDETAILPAYROLL.EMPMISCADD, EMPDETAILPAYROLL.EMPGRSAL, " & _

    " FROM EMPLOAN RIGHT JOIN (((EMPDETAILPERSONAL INNER JOIN CSDEPT ON EMPDETAILPERSONAL.EMPDEPT = CSDEPT.CSDEPTID) " & _
    " INNER JOIN EMPDETAILPAYROLL ON (EMPDETAILPERSONAL.EMPDESG = EMPDETAILPAYROLL.EMPDESG) AND (EMPDETAILPERSONAL.EMPDEPT = EMPDETAILPAYROLL.EMPDEPT) " & _
    " AND (EMPDETAILPERSONAL.EMPCODE = EMPDETAILPAYROLL.EMPCODE)) INNER JOIN CSDESIGNATION ON EMPDETAILPERSONAL.EMPDESG = CSDESIGNATION.CSDESGID) " & _
    " ON EMPLOAN.EMPCODE = EMPDETAILPERSONAL.EMPCODE " & _
    " WHERE EMPDETAILPERSONAL.EMPDOL Is Null ORDER BY IIF(EMPDETAILPERSONAL.EMPDESG = 1, '10','20') + EMPDETAILPERSONAL.EMPCODE", _con)
    _da.Fill(_dtEmp)

    dgEmp.DataSource = _dtEmp

在cellchanged事件中没有任何内容。甚至在触发cellchanged事件之前重置值。请帮忙。感谢

您应该确保datatable的相应列不是整数类型。如果给定列是某种integer，则此条件会反映在datagrid列中，当您输入带小数的值时，它们会被转换回integer。

允许数据网格控件接受小数值vb.net
