Creating a 2 column list of items from 1 list of items
I've used a javascript function before to create checkbox lists inside a table with a certain amount of columns.
function BuildCheckBoxList(array, jqloc, name, limit, startchecked)
{
///<summary>Used to create a generic checkbox list of items.</summar>
///<param name="array" type="List<I_S>">Array that is used to populate the checkboxes</param>
///<param name="jqloc" type="JQuery Object">JQuery object where the checkbox list is to be appended to</param>
///<param name="name" type="string">This is used to give your checkbox list a name/id/classes</param>
///<param name="limit" type="int">The amount of columns you want for each of the checkboxes.</param>
name = name.split(' ').join('_').split('.').join('_');
var html = "";
var limitcounter = 0;
html += "<table class='chktable' id='CheckBoxListTable-" + name + "'><tr>";
var checked = "";
if (startchecked)
{
checked = "checked='checked'";
}
for (var a = 0; a < array.length; a++) {
limitcounter++;
html += "<td class='cell'>";
html += "<div>";
html += "<input id='" + name + "-" + a + "' class='bcbl " + name + "' type='checkbox' " + checked + " value='" + array[a].name + "' /> ";
html += "<div class='bcbltext'>" + array[a].name + "</div>";
html += "</div>";
html += "</td>";
if (limitcounter == limit) {
html += "</tr><tr>";

}
}
html += "</tr></table>";
jqloc.html(html);
}
What I'm trying to do now is create a view that does the same thing. But I'm running into problems. Below is how I imagined it would work, but something is wrong. (@Model.limit is 2)
<table>
@limit = @Model.limit;
@counter = 0;
<tr>
@foreach (var item in Model.data)
{
@counter++;
<td>
@Html.DisplayFor(modelItem => item.Name)
</td>
<td>
<div id="Team-@item.Id-FilterRadio" class="TeamFilterRadio">
<input type="radio" id="Team-@item.Id-ON" name="Team-@item.Id" checked="checked"/><label for="Team-@item.Id-ON"">ON</label>
<input type="radio" id="Team-@item.Id-OFF" name="Team-@item.Id" /><label for="Team-@item.Id-OFF"">OFF</label>
</div>
</td>
@if (counter == limit){
</tr><td>
@counter = 0;
}
}
</tr>
</table>
I get this error : Parser Error Message: The foreach block is missing a closing "}" character. Make sure you have a matching "}" character for all the "{" characters within this block, and that none of the "}" characters are being interpreted as markup.
I removed the code where your checking the limit and it works. I think the problem your having is because your tags aren't closed as expected. I ran into a similar problem trying to nest some data like this. I ended up changing my model to accommodate. I found I couldn't conditionally close tags, because the Razor engine can't figure that out during design.
<table>
@{var limit = @Model.limit;
var counter = 0;
}
<tr>
@foreach (var item in Model.data) {
@{counter++;}
<td>@Html.DisplayFor(modelItem => item.Name)</td>
<td>
<div id="Team-@item.Id-FilterRadio" class="TeamFilterRadio">
<input type="radio" id="Team-@item.Id-ON" name="Team-@item.Id" checked="checked"/><label for="Team-@item.Id-ON"">ON</label>
<input type="radio" id="Team-@item.Id-OFF" name="Team-@item.Id" /><label for="Team-@item.Id-OFF"">OFF</label>
</div>
</td>
}
</tr>
</table>
You could do something like this. I created a class TestData with the properties your using, and my Data property of my model is of type generic list of TestData. I tested using 13 items and both 2 and 3 columns and it worked like a charm.
@{int i = 0;
var item = new MVC3TestSite.Models.TestData();
}
<table>
@while(i < Model.Data.Count){
<tr>
@for(var j = 1; j <= Model.Limit; j++){
item = Model.Data[i];
<td>@item.Name</td>
<td>
<div id="Team-@item.Id-FilterRadio" class="TeamFilterRadio">
<input type="radio" id="Team-@item.Id-ON" name="Team-@item.Id" checked="checked"/><label for="Team-@item.Id-ON"">ON</label>
<input type="radio" id="Team-@item.Id-OFF" name="Team-@item.Id" /><label for="Team-@item.Id-OFF"">OFF</label>
</div>
</td>
if (++i == Model.Data.Count) { break; }
}
</tr>
}
</table>
