Grouping/GROUP BY With LINQ in MVC - asp.net-mvc

Question

I am new in MVC. In this page; I list the projects belonging to the "unit name" by loop. And what I want to do: I want to group projects belonging to the same "unit name". Each project has a "unit name" to which it belongs. There can be more than one project belonging to one unit. So I want to group it.
My cshtml code is as follows:
#if (Model.Projects.Any())
{
foreach (var item in Model.Projects.ToList())
{
<div class="ProjectPartialBody" data-id="#item.ID">
<div class="portlet box blue">
<div class="portlet-title">
<div class="caption">
<span><i class="glyphicon glyphicon-asterisk"></i> #item.tbl_Unit.Name</span>
</div>
<div class="tools">
</div>
<div class="actions">
Details
</div>
</div>
<div class="portlet-body">
<span><i class="fa fa-file"></i> #item.Name</span>
<span><i class="fa fa-calendar"> Contract Start and End Dates: #(item.ContractStartDate != null ? item.ContractStartDate.Value.ToString("dd.MM.yyyy") : "-") / #(item.ContractEndDate != null ? item.ContractEndDate.Value.ToString("dd.MM.yyyy") : "-")</i></span>
<div class="well">
<div class="form-group">
<label>Cash Completion Rate: %#item.CashCompletionRate</label>
<div class="progress progress-striped active">
<div class="progress-bar progress-bar-info" role="progressbar" style="width: #(item.CashCompletionRate)%;"></div>
</div>
</div>
</div>
<div class="well">
<div class="form-group">
<label>Physical Completion Rate: %#item.PhysicalCompletionRate</label>
<div class="progress progress-striped active">
<div class="progress-bar progress-bar-info" role="progressbar" style="width: #(item.PhysicalCompletionRate)%;"></div>
</div>
</div>
</div>
</div>
</div>
</div>
}
}
And the view of the page is as follows (my view is in Turkish language but you'll understand what I am talking about):

Can you please help me? And if there is any other code block you want to insert, please tell me.

Answer 1

You first need to group by in your for statement:
foreach(var unitGroup in Model.Projects.GroupBy(g => g.tbl_Unit.Name))
{
//...your MVC markup here
}
Now you actualy need to change the markup as you would need to put in another foreach loop that would generate markup for projects.
So something simillar to this.
<div class="ProjectPartialBody" data-id="#item.ID">
<div class="portlet box blue">
<div class="portlet-title">
<div class="caption">
<span><i class="glyphicon glyphicon-asterisk"></i> #item.tbl_Unit.Name</span>
</div>
<div class="tools">
</div>
<div class="actions">
Details
</div>
</div>
#foreach(var project in unitGroup.ToList())
{
<div class="portlet-body">
<span><i class="fa fa-file"></i> #project.Name</span>
<span><i class="fa fa-calendar"> Contract Start and End Dates: #(project.ContractStartDate != null ? project.ContractStartDate.Value.ToString("dd.MM.yyyy") : "-") / #(project.ContractEndDate != null ? project.ContractEndDate.Value.ToString("dd.MM.yyyy") : "-")</i></span>
<div class="well">
<div class="form-group">
<label>Cash Completion Rate: %#project.CashCompletionRate</label>
<div class="progress progress-striped active">
<div class="progress-bar progress-bar-info" role="progressbar" style="width: #(project.CashCompletionRate)%;"></div>
</div>
</div>
</div>
<div class="well">
<div class="form-group">
<label>Physical Completion Rate: %#project.PhysicalCompletionRate</label>
<div class="progress progress-striped active">
<div class="progress-bar progress-bar-info" role="progressbar" style="width: #(project.PhysicalCompletionRate)%;"></div>
</div>
</div>
</div>
</div>
}
</div>
</div>
There should be some errors here as I am not very familliar with your model but this should be the general idea behind it.
