Check/Unchecked All CheckBoxes in Repeater

Jul 08, 2010 05:05 PM|LINK

Hi All,

I tried some of the example from the web, but all of them will check/uncheck all the checkboxes in the form, NOT only in the repeater. Is there a way to implement this and only apply to repeater.

Thanks.

You can do something like this:
```
foreach (RepeaterItem item in Repeater1.Items)
        {
            CheckBox cb = (CheckBox)item.FindControl("CheckBox1");
            if (cb != null)
            {
                cb.Checked = true;
                //cb.Checked = false;
            }
        }
```
where the ID of the checkbox in your repeater is "CheckBox1".

<div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> foreach (RepeaterItem item in Repeater1.Items)</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> {</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> CheckBox cb = (CheckBox)item.FindControl("CheckBox1");</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> cb.Checked = true;</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> //cb.Checked = false;</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> </div>

you can try this:

<div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste">using System.Linq;</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> repeater.Items.OfType<RepeaterItem>().ToList().ForEach(a=>((CheckBox)a.FindControl("CheckBoxID")).Checked=true);</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> repeater.Items.OfType<RepeaterItem>().ToList().ForEach(a => ((CheckBox)a.FindControl("CheckBoxID")).Checked = false);</div>
```
using System.Linq;
            repeater.Items.OfType<RepeaterItem>().ToList().ForEach(a=>((CheckBox)a.FindControl("CheckBoxID")).Checked=true);
            repeater.Items.OfType<RepeaterItem>().ToList().ForEach(a => ((CheckBox)a.FindControl("CheckBoxID")).Checked = false);
```

if that's where you want to check/uncheck all the checkboxes, yes.

You'll need to set AutoPostBack="true".
