How to use a Twitter Bootstrap icon inside an ASP.

问题:

How can I use a:

<i class="icon-etc"></i> 

with an asp.net button?

回答1:

LinkButton, like this...

<asp:LinkButton ID="SelectButton" runat="server" CssClass="btn btn-info"><i class="icon-ok icon-white"></i>&nbsp;Select</asp:LinkButton>

回答2:

You may add the <i> tag as a value to the LinkButton Text attribute.

e.g.

<asp:LinkButton ID="btnExcluir" runat="server" Text="<i aria-hidden='true' class='icon-remove-3'></i>" CssClass="btn btn-danger" />

You can even use it with a side text.

e.g.

<asp:LinkButton ID="btnExcluir" runat="server" Text="Link Name&nbsp;<i aria-hidden='true' class='icon-remove-3'></i>" CssClass="btn btn-danger" />

回答3:

try this

<asp:LinkButton ID="btnExample" runat="server" Text="<span class='glyphicon glyphicon-repeat'></span> Button" CssClass="btn btn-primary btn-xs" OnClick="btn_Click"></asp:LinkButton>

or

<asp:LinkButton ID="btnExample" runat="server" Text="<i class='glyphicon glyphicon-flash'></i> Button" CssClass="btn btn-primary btn-xs" OnClick="btn_Click"></asp:LinkButton>

I have done like this.

Markup:

<asp:PlaceHolder ID="phButtonToLabelsAdminBox" runat="server"></asp:PlaceHolder>
<asp:Button ID="btnSave" runat="server" CssClass="btn" Text="Spara" />
<asp:Button ID="btnClear" runat="server" CssClass="btn" Text="Töm/Ny" />

CodeBehind Page_Load()

FixGlyph(phButtonToLabelsAdminBox, btnSave, "icon-ok")
FixGlyph(phButtonToLabelsAdminBox, btnClear, "icon-refresh")

And the Sub:

Private Sub FixGlyph(ph As PlaceHolder, btn As Button, IconClass As String, Optional CustomLabelStyle As String = "")

If btn.Visible = False Then Exit Sub
Dim g As New HtmlGenericControl
g.ID = "labelFor_" + btn.ID
g.TagName = "label"
g.Attributes.Add("for", btn.ClientID)
g.Attributes.Add("class", "" + btn.CssClass + "")
If Not CustomLabelStyle = "" Then g.Attributes.Add("style", CustomLabelStyle)
g.InnerHtml = "<i class=""" + IconClass + """></i> " + btn.Text
ph.Controls.Add(g)
btn.Attributes.Add("style", "display:none;")

End Sub

I use ordinary asp:Button in my Markup and the only things are that to run the FixGlyph after other code that might set visible true/false for the buttons and to add the FixGlyph in the order you want the buttons to appear. Other than that, it works for me.

Thanks Anders Smedman, your code sure did the job. here is the C# code if anyone needs it.

 private void FixGlyph(PlaceHolder ph, Button btn, string iconClass, string customLabelStye = "")
    {
        if (btn.Visible)
        {
            var g = new HtmlGenericControl();
            g.ID = "labelFor_" + btn.ID;
            g.TagName = "label";
            g.Attributes.Add("for",btn.ClientID);
            g.Attributes.Add("class","" + btn.CssClass +"");
            if (customLabelStye != "")
            {
                g.Attributes.Add("style",customLabelStye);
            }
            g.InnerHtml = "<i class='" + iconClass + "'></i> " + btn.Text;
            ph.Controls.Add(g);
            btn.Attributes.Add("style","display:none;");
        }

    }
