Html ASP NET SQL-为每行创建一个新div_Html_Asp.net_Sql Server_Vb.net_Foreach - Fatal编程技术网

Html ASP NET SQL-为每行创建一个新div

Html ASP NET SQL-为每行创建一个新div,html,asp.net,sql-server,vb.net,foreach,Html,Asp.net,Sql Server,Vb.net,Foreach,正在寻找一种解决方案,以便为SQL Server数据库表中的每一行创建一个包含其内容的新div: Dim com As SqlCommand = New SqlCommand("select Date,Title,Content from Log where Author = @Author", con) com.Parameters.Add("@Author", SqlDbType.Char) com.Parameters("@Author").Value = User.Identity.Na

正在寻找一种解决方案,以便为SQL Server数据库表中的每一行创建一个包含其内容的新div:

Dim com As SqlCommand = New SqlCommand("select Date,Title,Content from Log where Author = @Author", con)
com.Parameters.Add("@Author", SqlDbType.Char)
com.Parameters("@Author").Value = User.Identity.Name

Dim dt As DataTable = New DataTable()

For Each Datarow In dt.Rows
       //create New div with its content
Next
这一个正在工作,但是还不能让它创建一个包含其内容的新div/表

谢谢你的帮助

DataSet ds = new DataSet();
SqlDataAdapter da1 = new SqlDataAdapter("select Date,Title,Content from Log where Author = @Author", ConfigurationManager.ConnectionStrings["sasa"].ConnectionString);
 da1.Fill(ds);
 string makehtml = string.Empty;
//however when you have DataSet then you can iterate easily and cerate whatever you want
    for(int i = 0; i < ds.Tables[0].Rows.Count; i++)
    {
        makehtml += "<div><span>Date:</span> " + ds.Tables[0].Rows[i]["Date"] + " <span>Title:</span> " + ds.Tables[0].Rows[i]["Title"] + "< span > Content:</ span > " + ds.Tables[0].Rows[i]["Content"] + " </div>";
    }
您还可以使用repeater代替Listview。 另一种方法可以完成相同的操作:

 <%-- statrt here --%>
            <% if (ds.Tables[0].Rows.Count > 0){
                    for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                    {%>
            <div class="col-md-12">
                <div class="col-md-12"><span>Date:</span><%=ds.Tables[0].Rows[i]["Date"].ToString()%>
                <span>Title:</span><%=ds.Tables[0].Rows[i]["Title"].ToString()%><span> Content:</span><%=ds.Tables[0].Rows[i]["Content"].ToString()%></div>
            </div>
            <%}} %>
            <%-- Ends here --%>

…希望这段代码有帮助

在Web表单中,通常的做法是将数据表绑定到某种控件,如转发器。您知道如何将css样式应用于div吗?如下面的
makehtml+=“css将正常工作。您可以使用style属性,也可以使用css类。例如:@Luke发送一个示例,然后我将完全理解您的css问题。如果css类不工作,请尝试使用内联css。在Web表单中向网页添加重复内容,这确实是一种可怕的方式。”。
