创建动态div标签， [英] creating dynamic div tag,

问题描述

我创建了动态超链接并从数据库中获取了数据。现在我需要将这些数据放在特定的div标签中。请帮助我。

 <   div       runat   =  server    id   =  bdy < span class =code-keyword>>  
 <   / div  >  

  protected   void  Page_Load（ object  sender，EventArgs e） 
 {
 
 
 MySqlCommand inscmd =  new  MySqlCommand（  select * from category，con）; 
 MySqlDataAdapter a =  new  MySqlDataAdapter（inscmd）; 
 DataTable t =  new  DataTable（）; 
 
  foreach （DataRow row  in  t.Rows）
 { 
 bdy.InnerHtml.Equals（ < a href = \category.aspx？refid =  + row [  cid] +    \> + row [  catname] +  < / a>< br />）; 
 
  //   bdy是div name  
 Response.Write（  < a href = \category.aspx？refid = + row [  cid] +   \> + row [  catname] +  < / a>< br />）; 
 
} 
} 

解决方案

我们可以在数据行的循环中构建超链接内容然后将它分配给div的innerHTML。

 SqlDataAdapter适配器; 
 DataTable dt; 
 string mystr; 
 
 adapter = new SqlDataAdapter（选择catid，catname from category，myconnstring）; 
 adapter.Fill（dt）; 
 mystr =; 
 
 foreach（dt.Rows中的DataRow dr）
 {
 mystr = mystr +< a href ='category.aspx？refid =+ dr（catid ）+'> + dr（catname）+< / a>< / br>; 
} 
 
 mydiv.InnerHtml = mystr; 
 

 HtmlGenericControl bdy =  new  HtmlGenericControl（   div）; 
 
 HtmlGenericControl aTag =  new  HtmlGenericControl（ 一个）; 
 aTag.Attributes.Add（  href， 您的网址）; 
 
 bdy.Controls.Add（aTag）; 
 
你也应该在 html页面中使用Panel 然后使用
 
 panel.Controls.Add（bdy） ; 

I have created dynamic hyperlink and fetched data from database. now i need to put those data in particular div tag. Please help me.

<div  runat="server" id="bdy">
</div>

protected void Page_Load(object sender, EventArgs e)
{


    MySqlCommand inscmd = new MySqlCommand("select * from category", con);
    MySqlDataAdapter a = new MySqlDataAdapter(inscmd);
        DataTable t = new DataTable();

    foreach (DataRow row in t.Rows) 
            {
                bdy.InnerHtml.Equals("<a href=\"category.aspx?refid=" + row["cid"] + "\">" + row["catname"] + "</a><br />"); 

        // bdy is div name 
                 Response.Write("<a href=\"category.aspx?refid="+row["cid"]+"\">"+row["catname"]+"</a><br />");               

           }
}

解决方案

We can build the hyperlink content in the loop of datarows and then assign it to the innerHTML of div.

SqlDataAdapter adapter;
DataTable dt;
string mystr;

adapter = new SqlDataAdapter("Select catid, catname from category", myconnstring);
adapter.Fill(dt);
mystr = "";

foreach (DataRow dr in dt.Rows)
{
    mystr = mystr + "<a href='category.aspx?refid=" + dr("catid") + "'>" + dr("catname") + "</a></br>";
}

mydiv.InnerHtml = mystr;

HtmlGenericControl bdy = new HtmlGenericControl("div");

HtmlGenericControl aTag = new HtmlGenericControl("a");
aTag.Attributes.Add("href","your url");

bdy.Controls.Add(aTag);

also you should use a Panel in the html page and then  

panel.Controls.Add(bdy);
