Using if in a label

Radzen Studio Blazor Server
1

Just a quick question on divide by zero instances. I have a few columns on a dashboard that divide one variable by another. Other than using set property for each and every one, I thought maybe I could just use an if statement in the label, but I just keep getting errors. Following is one statement, would love a little feedback on how to use an if statement in this case or let me know a different way to handle this.

${String.Format("{0:F0}", (TotalNew/DaysWorked)*DaysInMonth)}

Tried

if (${TotalNew} >0);
${String.Format("{0:F0}", (TotalNew/DaysWorked)*DaysInMonth)};

You should use the C# ternary operator.

${TotalNew > 0 ? String.Format("{0:F0}", (TotalNew/DaysWorked)*DaysInMonth) : ""}

Thank you soooo much...I knew I was missing something, just looking at it too long and couldn't see the solution!!!

I might need more guidance on that. I am using
<RadzenLabel Text="@(${data.LastDocumentDate == null : "" : data.LastDocumentDate.ToString()})">
and it doesn't work.

Should be:

(data.LastDocumentDate == null : "" : data.LastDocumentDate.ToString())

7

So <RadzenLabel Text="@(${(data.LastDocumentDate == null : "" : data.LastDocumentDate.ToString())})">?
Unfortunately this still doesn't work.

This is how you define string interpolation in C# while in your case after this symbol there is no string.

For future post readers, this is what finally worked:
@{
string documentDate = data.LastDocumentDate != null ? data.LastDocumentDate.ToString() : "";
}
RadzenLabel Text=@documentDate

This will work as well:

<RadzenLabel Text="@($"{(data.LastDocumentDate == null ? "" : data.LastDocumentDate.ToString())}")" />

or simply:

<RadzenLabel Text="@($"{data.LastDocumentDate}")" />

since null will become empty string.

You can simplify it even more like this:

<RadzenLabel Text=@($"{data.LastDocumentDate}") />
