I want to have a column as row number
in MVC WebGrid. How can I do it?
@{
int i=0;
foreach (var item in Model) {
<tr>
<td>
@i
</td>
<td>
@Html.DisplayFor(modelItem => item.Expense)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=item.Id }) |
@Html.ActionLink("Delete", "Delete", new { id = item.Id }, new { onclick = "return confirm('Are you sure you wish to delete this record?');" })
</td>
</tr>
i++;
}
}
Try this
You could use a view model that will contain a property indicating the row number.
Let's suppose that you have the following domain model:
public class DomainModel
{
public string Foo { get; set; }
}
Now you build a view model that will correspond to the requirements of your view:
public class MyViewModel
{
public int RowNumber { get; set; }
public string Foo { get; set; }
}
and then:
public ActionResult Index()
{
// fetch the domain model from somewhere
var domain = Enumerable.Range(1, 5).Select(x => new DomainModel
{
Foo = "foo " + x
});
// now build the view model
// TODO: use AutoMapper to perform this mapping
var model = domain.Select((element, index) => new MyViewModel
{
RowNumber = index + 1,
Foo = element.Foo
});
return View(model);
}
Now your view becomes strongly typed to the view model of course:
@model IEnumerable<MyViewModel>
@{
var grid = new WebGrid(Model);
}
@grid.GetHtml(
columns: grid.Columns(
grid.Column("RowNumber"),
grid.Column("Foo")
)
)
Now let's suppose that for some foolish reason you don't want to use view models. In this case you could turn your view into spaghetti code if you prefer:
@model IEnumerable<DomainModel>
@{
var grid = new WebGrid(Model.Select((element, index) => new { element, index }));
}
@grid.GetHtml(
columns: grid.Columns(
grid.Column("RowNumber", format: item => item.index + 1),
grid.Column("Foo", format: item => item.element.Foo)
)
)
simply add the following code
grid.Column(header: "No."
,format: item => item.WebGrid.Rows.IndexOf(item) + 1
+ Math.Round(Convert.ToDouble(grid.TotalRowCount / grid.PageCount) / grid.RowsPerPage)
* grid.RowsPerPage * grid.PageIndex)

hope this will be helpful to someone
Add this:
grid.Column(header: "No.",
format: item => item.WebGrid.Rows.IndexOf(item) + 1 + Math.Round(Convert.ToDouble(grid.TotalRowCount / grid.PageCount) / grid.RowsPerPage) * grid.RowsPerPage * grid.PageIndex)
That's a really nice approach, but when you use sorting or paging your RowNumber
values won't start from 1 on the page.
In my project I had a case where I needed to know an index of the row independently of WebGrid's paging / sorting and I came across the following solution:
grid.Column(
Header: "RowNumber",
Format: item => item.WebGrid.Rows.IndexOf(item) + 1
)
