Using IF Statements inside webgrid column aspnet mvc c#

Question

User-1453200658 posted

Hi all,

In MVC aspnet C# project I have setting an Webgrid.

In edit web grid the value of the day_gv it's always null and required.

But if the value of bool Truefalse is set to true I need set as "0000-00-00" the day_gv field.

I have tried code below without success.

Can you help me?

webGrid.Column(
header: "day_gv",
style: "day_gv",
format: @<span>
    <span class="label">@item.day_gv</span>
    @item.Truefalse ? 
<input class="text name" type="text" value="@item.day_gv" style="display:none" /> : 
<input class="text name" type="text" value="0000-00-00" style="display:none" />
</span>),

Rather than rendering two different inputs, just set the day_gv variable to 0000-00-00.  This can be done in the model by setting a default value.

thanks fo reply, but I can't set the day_gv variable to 0000-00-00 because this value it may already have been inserted into the database when editing row on webgrid

In this case I need show the value of day_gv variable and not default 0000-00-00 value.

For this I need rendering two different inputs

Your response makes no logical sense.   You're making a very simple programming construct overly complex.  The UI design should have one input which can have a variable value.  That's how inputs work.  

Did you try a default value??? 

public string day_gv {get; set;} = "0000-00-00";

Or setting set the input value using Razor syntax.

value='@(item.Truefalse ? "0000-00-00" : item.day_gv)'

Can you explain what you mean by because this value it may already have been inserted into the database when editing row on webgrid?  Why are you unable to fetch the actual value form the database???  Also is day_gv a string?  DateTime???
