I'm trying to create a simple store locator on an ASP.NET page. I have the user enter their zipcode, then C# creates a variable with it and appends it to the end of a url to search for that store on Google maps near them. I then need it to dynamically add an iframe tag with it's source as that url to the page.
Something like:
<asp:TextBox ID="TextBox1" placeholder="Zip code" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Find locations" onclick="Button1_Click" />
And:
protected void Button1_Click(object sender, EventArgs e)
{
var zipCode = TextBox1.Text;
HtmlGenericControl iframe = new HtmlGenericControl();
iframe.ID = "iframe";
iframe.TagName = "iframe";
iframe.Attributes["class"] = "container";
iframe.Attributes["src"] = "https://www.google.com/maps/preview#!q=gnc+near%3A+" + zipCode;
this.Add(iframe);
}
I believe it's correct until the last line, any thoughts?
You can actually add runat="server"
to any standard HTML tag on the page in ASP.NET webforms. Try this on your page:
<iframe id="MyIframe" runat="server"></iframe>
This will give you access to your iframe by name in code behind. You'll then be able to manipulate things by writing statements like:
MyIframe.Visible = true;
and
MyIframe.Attributes.Add("src", "https://www.google.com/maps/preview#!q=gnc+near%3A+" + zipcode);
