我有一个gridview,它有列(Id,Task,Reward,Time Allotted,Uploader)..我可以成功地将数据插入gridview,直到第13页的taskId 118,但之后数据开始显示在在TaskId 7之后的第1页。
所以序列就像.... 5,6,7,119,120,121,122,8,9,10 ..... 所以所有的新数据都插在7到8之间。为什么?我怎么能纠正这个?
我不认为这是代码错误,但仍然是我的:
protected void btnPost_Click(object sender, EventArgs e)
{
string CS = ConfigurationManager.ConnectionStrings["EasyRozMoney_ConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
SqlCommand cmd = new SqlCommand("spTasks", con);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@Title", txtTitle.Text);
cmd.Parameters.AddWithValue("@Body", txtBody.Text);
cmd.Parameters.AddWithValue("@Reward", txtRewards.Text);
cmd.Parameters.AddWithValue("@TimeAllotted", txtTime.Text);
cmd.Parameters.AddWithValue("@PosterName", txtPoster.Text);
con.Open();
cmd.ExecuteNonQuery();
lblStatus.Text = "Task Posted Successfully.";
}
这是gridview:
<asp:GridView ID="GridView1" runat="server" Width="936px" AllowPaging="True" AutoGenerateColumns="False" CellPadding="3" DataSourceID="SqlDataSource1" OnRowCommand="GridView1_RowCommand" style="text-align: center" BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px" CellSpacing="2" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:BoundField DataField="TaskId" HeaderText="TaskId" InsertVisible="False" ReadOnly="True" SortExpression="TaskId" />
<asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" />

</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:EasyRozMoney_ConnectionString %>" SelectCommand="SELECT * FROM [Task]"></asp:SqlDataSource>
我在sql中的表格如下:
Create table Task
(
TaskId int Identity(1,1),
Title varchar(100),
Body varchar(500),
Reward decimal(4,2),
TimeAllotted int,
PosterName varchar(100)
)
我的存储过程:
Create proc spTasks
@Title varchar(100),
@Body varchar(500),
@Reward decimal(4,2),
@TimeAllotted int,
@PosterName varchar(100)
as
begin
Insert into Task values(@Title,@Body,@Reward,@TimeAllotted,@PosterName)
end

您可以更改数据源的select语句的默认排序。如果您希望最近的记录显示在最后:默认排序,如果您希望它们首先显示在您的网格中:按降序排序。
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:EasyRozMoney_ConnectionString %>"
SelectCommand="SELECT * FROM [Task] ORDER BY TASKID"></asp:SqlDataSource>
在备注中,您应该使用select&#39; *&#39;仅在测试用例中。在现实世界的场景中,这将导致执行表扫描的性能下降。在select语句中,只选择在UI中显示所需的列。
正如其他人指出的那样,请检查数据库列中int或varchar类型,如果以后可以将列转换为int,或者更好地将其创建为int。
