How to dynamically change meta tags when using MasterPage in ASP.NET and C# Samples and examples

Someone asked me yesterday about - how to dynamically change meta tags when using MasterPage in ASP.NET and C#. Lots of beginners are searching for a solution all over the internet but some articles are difficult to understand for them. So this one is intended for beginners.

When you have lots of dynamic pages instead of static, you may want to change the Meta Keywords dynamically which is helpful in SEO (Search Engine Optimization).

The solution to this is to first provide an id to your Head Tag in Master Page :


<head runat="server" id="mainHead">

Now in the page where you want to change the Meta tags dynamically add the following code sample on the page load event :


//Find the Head Tag in Master Page
        HtmlHead hdMain = (HtmlHead)Page.Master.FindControl("mainHead");
        HtmlMeta htmMeta = new HtmlMeta();
        htmMeta.Attributes.Add("name","description");
        htmMeta.Attributes.Add("content", "This is content");
        //Add Meta Tag to Head 
        
        hdMain.Controls.Add(htmMeta);

        //Adding keyword Meta Tag to Head Section
        HtmlMeta hm2 = new HtmlMeta();
        hm2.Attributes.Add("name", "keywords");
        hm2.Attributes.Add("content", "Here you can pass your keywords");
        hdMain.Controls.Add(hm2);

And that’s it! Now view the page source and you will find the description and keyword tags there.
