数据未显示在网格控件Asp.net C#中，但显示在DataTable中

我有5个文本框和两个下拉列表。我将在文本框中输入数据，单击“添加”按钮后，所有数据在VS2017的数据表中显示。我可以看到Datatable中的数据，但无法看到aspx页面中的数据。 如何将数据表中的数据绑定到网格控件，以便用户可以看到数据

以下是CS页面的代码：

            Griddt.Columns.Add("SrlNo", typeof(string));
            Griddt.Columns.Add("GrnNo", typeof(string));

有人能给我一些建议吗？如何将数据表中的数据绑定到网格控件。

问题可能出在aspx页面上。你能把网格定义放在asp中吗？我已经把网格定义上传到了aspmmm中。奇怪。在数据源的DtAll不工作之前，可能尝试获取dgv visible=true。。。网格上没有显示任何数据。。。

function fnCheckValidation()
{
    var Item= document.getElementById("ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1_ddlItem");
    var ItemName=document.getElementById("ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1_txtItemName");
    var ChallanQty=document.getElementById("ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1_txtChallanQty");
    var ActuallQty =document.getElementById("ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1_txtActuallQty");
    var TotChalan=document.getElementById("ctl00_ContentPlaceHolder1_txtTotChallanQty");
    var TotRecvd= document.getElementById("ctl00_ContentPlaceHolder1_txtTotRecvdQty");

if(Item.value=="")
    { 
        alert("Please Select Item!");
        Item.focus();
        return false; 

    }

    if(ChallanQty.value=="")
    {
        alert("Please Enter Challan Qty!");
        return false; 
    }

    if(ActuallQty.value=="")
    {
        alert("Please Enter Actuall Qty!");
        return false; 
    }

    TotChalan.readOnly= true;
    TotRecvd.readOnly= true;


    return true;
