Please past your code, and mention line when you getting error.
Your are converting string in Boolean, but the value of string is not (true,false), thats y this error occor

Anaya Upadhyay 8-Oct-13 7:03am

The error is on the line 1089 and the code goes like this:

1089: bool myValue;
1090: if(Boolean.TryParse(drow["IsTrue"].ToString(), out myValue))
1010: this.genderCheckBox.Checked = true;
1011: else
1012: this.genderCheckBox.Checked = false;

The error is on the line 1089 and the code goes like this:

1089: bool myValue;
1090: if(Boolean.TryParse(drow["IsTrue"].ToString(), out myValue))
1010: this.genderCheckBox.Checked = true;
1011: else
1012: this.genderCheckBox.Checked = false;

Do one thing
First You have to ensure that what type of value is coming inside drow["IsTrue"]

For this put a breakpoint there select the drow["IsTrue"] statement and put Quick Watch and see is the value is boolean type ?
If not then check your database and your query to send a boolean value

I am telling beacause Your error is string is not valid boolean.

Finally you can do it in a plain way
genderCheckBox.Checked=Convert.ToBoolean(drow["IsTrue"]);

Solution 2

Check this code,

C#

//The error is on the line 
//1089 and the code goes like this: 

//assign myValue you can't use unassinged variables
1089: bool myValue=false;

1090: if(Boolean.TryParse(drow["IsTrue"].ToString(), out myValue)) 
1010: this.genderCheckBox.Checked = true; 
1011: else 
1012: this.genderCheckBox.Checked = false;

// you can use following code also
bool myValue=false;

Boolean.TryParse(drow["IsTrue"].ToString(), out myValue);
this.genderCheckBox.Checked = myValue;

i've tried this. But the issue is, the same code runs in localhost but not in server (i mean when it is online).

MuhammadUSman1 9-Oct-13 0:38am

Are you sure that the error occurring on this code?
after initializing myValue = false,
?

Anaya Upadhyay 9-Oct-13 5:49am

100% sure

And i need to solve this within 12 hours. Please help.
As I said earlier, it runs well in localhost. But after hosting it on the Server the same line doesnot work.

MuhammadUSman1 9-Oct-13 23:51pm

Sorry Anaya i am too late,
but i don't think so that there is any issue in code.
Please declare myValue as static and try,
