我有一个gridview，当按下2个按钮时就会填充它。
https://www.easyallies.com/api/review/get使用import requests
from bs4 import BeautifulSoup
data = { 'method': 'review','action': 'get','data[start]': 0,'data[limit]': 10 }
reviews = requests.post("https://www.easyallies.com/api/review/get",data=data)
print (reviews.text)
函数，用新行创建 <asp:GridView ID="GridView1" runat="server"
ShowFooter="True" AutoGenerateColumns="False" Width="100%" Height="100%" HeaderStyle-BackColor="#3F51B5" HeaderStyle-ForeColor="White" BorderWidth="1px">
<Columns>
<asp:BoundField DataField="RowNumber" HeaderText="Nr.">
<ControlStyle BorderStyle="None" />
</asp:BoundField>
<asp:BoundField DataField="Message" HeaderText="Message">
<ControlStyle BorderStyle="None" />
</asp:BoundField>
<asp:BoundField DataField="Data" HeaderText="Data">
<ControlStyle BorderStyle="None" />
</asp:BoundField>
<asp:BoundField DataField="ClasaMesaj" HeaderText="ClasaMesaj">
<ControlStyle BorderStyle="None" />
</asp:BoundField>
</Columns>
</asp:GridView>
。 FirstGridViewRow()在GridView1
FirstGridViewRow()单击两个按钮之一，每次都添加新行。
PageLoad因此，在加载页面时， protected void Page_Load(object sender,EventArgs e)
{
if (this.IsPostBack)
return;
FirstGridViewRow();
}
private void FirstGridViewRow()
{
DataTable dt = new DataTable();
DataRow dr = null;
dt.Columns.Add(new DataColumn("RowNumber",typeof(string)));
dt.Columns.Add(new DataColumn("Message",typeof(string)));
dt.Columns.Add(new DataColumn("Data",typeof(string)));
dt.Columns.Add(new DataColumn("ClasaMesaj",typeof(string)));
dr = dt.NewRow();
dr["RowNumber"] = 1;
dr["Message"] = "";// string.Empty;
dr["Data"] = "";// string.Empty;
dr["ClasaMesaj"] = 0;
dt.Rows.Add(dr);
// dt.Rows.Remove(dt.Rows[0]); //I have tried like this,but no row would be added
ViewState["CurrentTable"] = dt;
GridView1.DataSource = dt;
GridView1.DataBind();
}
有1行（在 private void AddNewRow(string s,string s1,int ClasaMesaj)
{
int rowIndex = 1;
DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
DataRow drCurrentRow = dtCurrentTable.NewRow(); // null;// dtCurrentTable.NewRow();
for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
{
drCurrentRow["RowNumber"] = i+1;
drCurrentRow[1] = s;// "s";
drCurrentRow[2] = s1;// "s1";
drCurrentRow[3] = ClasaMesaj;
rowIndex++;
}
dtCurrentTable.Rows.Add(drCurrentRow);
ViewState["CurrentTable"] = dtCurrentTable;
GridView1.DataSource = dtCurrentTable;
GridView1.DataBind();
}
protected void Button1_Click(object sender,EventArgs e)
{
clsMsg = 1;
DateTime data = DateTime.Now;
string dt = data.ToString();
AddNewRow("Start",dt,clsMsg);
}
protected void Button2_Click(object sender,EventArgs e)
{
clsMsg = 2;
DateTime data = DateTime.Now;
string dt = data.ToString();
AddNewRow("Stop",clsMsg);
}
中初始化的行）。当我按下其中一个按钮时，将创建第2行。我想删除初始化的行，或者在按下按钮时用信息填充它。我该怎么办？我试图摆脱GridView1并仅使用FirstGridViewRow()，但没有成功。
