MudDataGrid: TemplateColumn identifier about mudblazor HOT 9 OPEN

Template collumn has a property called SortBy. This should work.

look at the unit tests:
https://github.com/MudBlazor/MudBlazor/blob/dev/src/MudBlazor.UnitTests.Viewer/TestComponents/DataGrid/DataGridSortableTemplateColumnTest.razor

from mudblazor.

ok but the sortBy will only give me in the ServerReload the identifier of the column, but the way i added the column doesn't allow me to recognise the column because the identifier given to the column is a random GUID

from mudblazor.

doesnt it work if you do:
<TemplateColumn Title="@(columnName)" Class="multiline-text" SortBy="x => (string)prop.GetValue(x)">

from mudblazor.

or
<TemplateColumn Title="@(columnName)" Class="multiline-text" SortBy="@(_ => columnName)">

from mudblazor.

I need to do the order by on server side because on client side i only have part of the data due to pagination. so i need to understand on the method ServerReload what column the user selected and pass that information to the server that will do the OrderBy

from mudblazor.

you should be able to use the DataGrid MudDataGrid<TItem> object to get the SortDefinitions.

in these objects you should be able to get all the information to build a request to your server and repopulate the itmes collection

Normally yes, but because i've created the columns using projection in foreach cycle there seems to be no way to know programmatically wich column the user want to order

Hi,

It would be nice if you attached a TryMudBlazor example to play with.

As a workaround, you can set the Title for the TemplateColumn, then get a ref of your MudDataGrid, iterate through RenderedColumns, find the TemplateColumn by that GUID, and extract the title.

from mudblazor.

Another option is to create your own TemplateColumn by inheriting Column<T> and override how the PropertyName behaves and use own logic instead of the random guid. I think all the needed tools are available.
