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（ 一个跨度>）; 
 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 />");               

           }
}

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);
