嘿那里，



假设您想从存储在ViewState中的DataTable中获取 BatchNo ：

Hey there,

Let's suppose you want to get BatchNo from the DataTable that you stored in the ViewState:

if(ViewState["BatchTable"] != null)
{
    DataTable dt= (DataTable)ViewState["BatchTable"];
 
    for(int i = 0; i < dt.Rows.Count; i++)
    {
        string batchNo = dt.Rows[i]["BatchNo"].ToString();
        if(batchNo.Equals("Your Value to Compare"))
        {
            //Do Something
        }
    }
}

希望这会有所帮助，请告诉我这是不是'你想要的是什么。

首先你将你的viewstate转换为像datatable这样的特定类型，List< clasobject>

然后你可以过滤它。

Ex。

DataTable myDt =（DataTable）ViewState [viewstatename];



来自myDt，您可以通过if条件过滤您的数据库

请参阅我没有给出任何代码它是一种理解概念的格式

First you have convert your viewstate to a specific type like datatable, List<clasobject>
Then you can filter it.
Ex.
DataTable myDt=(DataTable)ViewState["viewstatename"];

From myDt you can filter your datab by the if condition
See I have not given any code it's a format to understand the concept

首先要将此视图状态转换为数据表

例如



datattable abc =（datatable）viewstate（ temp）;

之后



你将输入abc.Rows [0] [sNO]。tostring（）



试试这个

first of All you have to convert this viewstate into datatable
For Example

datattable abc=(datatable)viewstate("temp");
after this

you will type abc.Rows[0]["sNO"].tostring()

try this
