我已成功将数据从xls导入dataGridView。 dataGridView中的date列显示DateTime格式。我希望这个日期列显示在＆＃34; dd MMM yyyy＆＃34;格式。我尝试过如下所示：
connExcel.Open()
Dim dtExcelSchema As DataTable
dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, Nothing)
Dim SheetName As String = dtExcelSchema.Rows(0)("TABLE_NAME").ToString()
connExcel.Close()
'Read Data from First Sheet
connExcel.Open()
cmdExcel.CommandText = "SELECT * From [" & SheetName & "]"
oda.SelectCommand = cmdExcel
oda.Fill(dt)
connExcel.Close()
dt.Columns(1).ToString("dd MMM yyyy")
'Bind Data to GridView
InvestorGridView.Caption = Path.GetFileName(FilePath)
InvestorGridView.DataSource = dt
InvestorGridView.DataBind()
但它给了我一个错误：
错误1重载解析失败，因为无法访问＆＃39; ToString＆＃39;接受这个数量的论点。 D：\ TMV \ TMV \ Project \ Investor \ Investor \ Investor.aspx.vb 68 9投资者

答案 0 :(得分：0)
您的方法不起作用，因为您在ToString上使用DataColumn，而DateTime没有像DataTable这样的重载。这无论如何都不起作用。 DataGridViewColumn的唯一方法是，如果您在每行中添加另一个具有适当格式的字符串列。
您应该使用InvestorGridView.Columns(1).DefaultCellStyle.Format = "dd MMM yyyy"
＆＃39; DefaultCellStyle：
BoundField 更新如果它是网络形式并且<asp:BoundField DataField="DateColumn"
HeaderText="DateColumn-Name"
SortExpression="DateColumn"
DataFormatString="{0:dd MMM yyyy}" />
您可以使用DataFormatString-property：
$scope.printBillDetailsOfCaseTreatment = function (billPaymentDetails, receiptNo) {
$scope.showBillDetailsOfCaseTreatment=true;
var url = urllist['printSetting']+$location.search().clinicId+"/Receipt" //ClinicId
$http.get(url,{cache:false}).success(function(data) {
var amountHeader = "";
var amount=0;
if(billPaymentDetails.waveOffFlag==false) {
amountHeader = "Payment Amount";
amount = billPaymentDetails.paymentAmount;
}
else {
amountHeader = "Waive Off Amount";
amount = billPaymentDetails.waveOffAmount;
