如何将 href 分配给代码隐藏中的锚标记 c#

Question

The text I inserted in database is

 You also have to click on is <a href="" target="_blank"> link </a>

This text I am assigning to the label when page loads. My requirement is when I click the "link" I need to redirect to certain page. How can I set the href to the above code in code behind.

Answer 1

Try to use HyperLink.

 <asp:HyperLink id="hyperlink1" 
                  ImageUrl="images/pict.jpg"
                  NavigateUrl="http://www.microsoft.com"
                  Text="Microsoft Official Site"
                  Target="_new"
                  runat="server"/>

Answer 2

You should add runat="server" to your anchor and then give an ID to it. So you can edit href property in codebehind.

in html side:

in code behind: xxxxx.HRef = "bla bla"

Look at this: How do you set href attribute of anchor tag that is within a repeater in code behind?

Assuming you can slightly change the format of what you put in the database then I'd do something along these lines:

string labelFromDatabase="You also have to click on is <a href=\"{0}\" target=\"_blank\"> link </a>";
string url = "mypage.aspx";
myLabel.Text = String.Format(labelFromDatabase, url);

Adding in the {0} placeholder into the database held string means you can easily just use String.Format to put in whatever url you want.

Main things to be aware of are that putting { or } in the DB string will need special care (since they are special characters when you pass it into String.Format . Also you will of course need to make sure that url is appropriately escaped if necessary (but that is the case with all solutions).

Answer 4

Try this

string Myurl="index.aspx";
label1.Text = "You also have to click on is <a href=" + Myurl+ " target="_blank"> link </a>

Answer 5

you need to store your string in database with some formate like this...

 "You also have to click on is <a href='{0}' target='_blank'> link </a>"

and when you assign that text to your lable at that time use string.formate method to add URL to href like this...

//get your database string
string _samplestring ="You also have to click on is <a href='{0}' target='_blank'> link </a>";
string _url ="http://stackoverflow.com/";
lbl.Text = string.Format(_samplestring, _url);

if you also need to assign something to target at run time then store your string like this..

"You also have to click on is <a href='{0}' target='{1}'> link </a>"

and use it like this...

//get your database string
string _samplestring ="You also have to click on is <a href='{0}' target='{1}'> link </a>";
string _url ="http://stackoverflow.com/";
string _target = "_blank";
lbl.Text = string.Format(_samplestring, _url,_target);

Answer 6

Use the following code for assigning string to href in anchor tag which is created in code behind

string strstring = "../master/YourPage.aspx?TransID="+ dr["TransId"];

Assign this string to url

marqueeText += "<a href='"+strstring+"'" + <span style='color:red;font-weight:bold;font-size:16px'>"
+ Convert.ToString(dr["SocietyName"]) + "</span></a>";

Hope this will help you.

simplest workaround is to add 'runat' attribute with 'server' value, and set Target and Href properties.

//in design

<a id="aBack" runat="server">
  <img src="backarrow.png" style="cursor: pointer;" width="32px" height="32px" />
</a>

//in Code behind C#

aBack.Target = "_parent";//to target parent page from iframe

aBack.HRef = url;
