Increase size of checkbox in asp.net?_问答_开发者

I really tried a lot to increase a size of checkbox in asp.net. using css style sheet but it doesn't work.

Might be I have done something wrong. I am try to increase the width, size and height of checkbox, but it doesnt happen yet.

开发者_JS百科

Can anyone provide C# code or css code that can do this?

In asp.net a checkbox will become a span with an input of type "checkbox"

In order to resize it, just apply a css class to the asp.net checkbox and add this to your style sheet. the style must be applied to the the embeded input of the checkbox like this :

<asp:CheckBox ID="chkBoxName" runat="server" CssClass="ChkBoxClass"/>

.ChkBoxClass input {width:25px; height:25px;}

Having a html checkbox.

<input type="checkbox" id="fatty">
<label for="checkbox-1">Checkbox 1</label>

fatty { /* Change width and height */
   width:4em;
   height:4em;
}

I got this from here.

A little late to the party but I'll leave this here for anyone else that needs help making check boxes bigger.

input[type=checkbox] {
    -ms-transform: scale(3); /* IE */
    -moz-transform: scale(3); /* FF */
    -webkit-transform: scale(3); /* Safari and Chrome */
    -o-transform: scale(3); /* Opera */
}

Example provided in the code snippet.

.scale1 {
    margin: 15px;
    -ms-transform: scale(1); /* IE */
    -moz-transform: scale(1); /* FF */
    -webkit-transform: scale(1); /* Safari and Chrome */
    -o-transform: scale(1); /* Opera */
}

.scale2 {
    margin: 15px;
    -ms-transform: scale(2); /* IE */
    -moz-transform: scale(2); /* FF */
    -webkit-transform: scale(2); /* Safari and Chrome */
    -o-transform: scale(2); /* Opera */
}

.scale3 {
    margin: 15px;
    -ms-transform: scale(3); /* IE */
    -moz-transform: scale(3); /* FF */
    -webkit-transform: scale(3); /* Safari and Chrome */
    -o-transform: scale(3); /* Opera */
}

<input id="cb1" type="checkbox" class="scale1">
<label for="cb1">scale1 </label>

<input id="cb2" type="checkbox" class="scale2">
<label for="cb2">scale2 </label>

<input id="cb3" type="checkbox" class="scale3">
<label for="cb3">scale3 </label>

for some reason, this doesn't worked for me:

   <asp:CheckBox id="requestAccountCB" style="width: 20px; height: 20px;" runat="server"/>

but this worked:

    <style>
        #requestAccountCB { width: 20px; height: 20px }
    </style>

...

    <body>
       <form runat="server">
           <asp:CheckBox id="requestAccountCB" runat="server"/>
       </form>
    </body>

As mentioned above, this can't be done.

What you can do is add a tag inside the checkbox and set a background image to that tag. It's all done with css and it works perfectly.

input[type=checkbox] {
display:none;
}

input[type=checkbox] + label
{
background-image: url('images/off.gif');
height: 16px;
width: 16px;
display:inline-block;
padding: 0 0 0 0px;
}

input[type=checkbox]:checked + label
{
background-image: url('images/on.gif');
height: 16px;
width: 16px;
display:inline-block;
padding: 0 0 0 0px;
}

And HTML code:

<input type='checkbox' name='thing' value='valuable' id="thing"/><label for="thing"></label>

The code can be found in this fiddle.

I found this solution here.

BTW: if you're using ASP.NET like me, you can add the label tag as so:

 <asp:CheckBox runat="server" ID="chkEmailForUnpluggedService" Text="<label for='thing'>" />

This solution works perfect for me:

Html Rendered looks like this:

<span class="15465503">
    <input id="ctl00_ctl00_ctl00_BB_SB_ScB_ucSR_rptR_ctl01_chkShortlist" 
     type="checkbox" name="ctl00$ctl00$ctl00$BB$SB$ScB$ucSR$rptR$ctl01$chkShortlist");">
</span>

CSS to change the check box size is:

input[id$="chkShortlist"] {
width: 18px;
height: 18px;
}

In 2021, if anybody still needs help with this - the multitude of answers above did not help me resize an ASP checkbox in an old WebForms application. Instead, adding the checkbox as a standard HTML Input element (as type="checkbox"), as opposed to an ASP:CheckBox, and then setting runat="server", helped me to be able to control this with inline styles, whilst still being able to control this in the code behind. E.g.

<input type="checkbox" id="cbInputDamagedStatus" style="width:1.5em; height:1.5em; display: inline-block;" runat="server" />

and

cbInputDamagedStatus.Checked = true;

You can't do it. A Checkbox is a windowed browser component. The best you can do is to make your own control that LOOKS like a checkbox, but is actually made up of an image for each state.

Here are some examples of controls that use images instead of checkboxes:
