Hi,
I have a html table in my view. I have checkboxes to select record and insert them into my table. here is my code :

<table id="dtsResult" class="table table-striped table-bordered" cellspacing="0" width="100%">
       <thead>
           <tr>
               <th>SelectAll<input type="checkbox" id="CheckAllRes" /></th>
               <th>Unit</th>
            </tr>
       </thead>
       <tbody>
           @foreach (var item in ViewBag.Result)
           {
               <tr>
                   <td><input type="checkbox" id=@item.RecordID name="res" class="chkres" /></td>
                   <td> @item.UnitNo</td>
               </tr>
           }
       </tbody>
   </table>

It's an old question, but as far as I can see, the accepted solutions don't work. If the checked attribute is present, the checkbox is checked. The attribute has to be omitted entirely - as you have done here - for the checkbox to be unchecked.

It might be simpler to use the Html.CheckBox helper method though. :)

The schema or task is unclear, as you have not explained how would you find the records that are added to the database. I would assume that your item object holds a property "IsSaved".

That said, the checkbox input can be altered for its state like this,

@foreach (var item in ViewBag.Result)
{
   <tr>
       <td>
            <input type="checkbox" checked="@item.IsSaved" 
            id="@item.RecordID" name="res" class="chkres" /></td>
       <td>@item.UnitNo</td>
   </tr>
}

This would now check for a value, either true or false. Then it would either check it, or leave it unchecked. That depends on your object. Implement it in a way that it represents your system.

Solution 1

HTML

@foreach (var item in ViewBag.Result)
          {
              <tr>
                  <td><input type="checkbox" id="@item.RecordID" name="res" class="chkres" checked="@item.IsChecked" /></td>
                  <td> @item.UnitNo</td>
              </tr>
          }

item.IsChecked has to be bool, and your ViewBag.Result must contain it.
