I new in ASP.NET. I try to print selected string in select option drop down but Compilation error.
Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement
Here is my cshtml code.
@{ string FromAMPM = "AM"; }
<select id="FromAMPM" name="FromAMPM" class="form-control js-select">
<option value=""></option>
<option value="AM" @if (FromAMPM == "AM") { "selected"; } else { ""; }>AM</option>
<option value="PM" @if (FromAMPM == "PM") { "selected"; } else { ""; }>PM</option>
</select>
What wrong? Thanks
You can use ternary conditional operator in your case:
@{ string FromAMPM = "AM"; }
<select id="FromAMPM" name="FromAMPM" class="form-control js-select">
<option value=""></option>
<option value="AM" @(FromAMPM == "AM" ? "selected='selected'" : "")>AM<</option>
<option value="PM" @(FromAMPM == "PM" ? "selected='selected'" : "")>PM<</option>
</select>
The best way would be separate logic and html
@{
var FromAMPM = "PM";
var items = new List<SelectListItem>
{
new SelectListItem { Value= "", Text="Select" },
new SelectListItem { Value= "AM", Text="AM" },
new SelectListItem { Value="PM", Text="PM"}
};
}
you don't neeed selected code, it will automatically select asp-for value
<select id="fromAMPM" asp-for="@FromAMPM" class="form-control js-select" asp-items="@items"></select>
