I have solved this query.The working code is as follows IIF((First(Fields!ShippingCase.Value DS_Invoice)).ToString().Equals(true) false true)

priyanka · Answer

it's nothing like that =IIF((Fields!ShippingCase.Value&Fields! DS_Invoice) ==true false true) since we are using Fields!ShippingCase.Value&Fields it throws this errorwhen we will use Fields!ShippingCase.Value it will remove this overloading error

Krishna Kumar · Answer

The error specifies that you are not reading the value of textbox properly. check on that and insert into that condition the it will work

priyanka · Answer

The Visibility.Hidden expression for the text box ‘SHIPPING_CHG’ contains an error: [BC30516] Overload resolution failed because no accessible 'IIf' accepts this number of arguments. here textbox '' SHIPPING_CHG is where i am putting expression

=IIF((Fields!ShippingCase.Value&Fields! DS_Invoice) ==true false true) Not Yet Workingafter using this

Krishna Kumar · Answer

Try this IIF((Fields!ShippingCase.Value&Fields! DS_Invoice) ==true false true)

Krishna Kumar · Answer

You can use terinary operator rather than IIF bool result=shippingcase.value=ds_invoice ? 1 : 0 It will give the result as 1 if the values are equal and result as 0 if the values are not equal.

priyanka · Answer

The Visibility.Hidden expression contains a colon or a line terminator. Colons and line terminators are not valid in expression. Please help me to resolve this.

Good Work. Need to change the textbox value to .Tostring.

Krishna Kumar · Answer

Try this =IIF((Fields!ShippingCase.Value DS_Invoice) ==true ? false : true)
