madhavi21.3966038613070422E12 I want to assign the string str as a expression value to checkbox.
public Component.Apex.InputCheckbox createchkbox()
{
Component.Apex.InputCheckbox chk=new Component.Apex.InputCheckbox();
Component.Apex.InputCheckbox test=new Component.Apex.InputCheckbox();
String str=NULL;
String type= 'FieldObject__c'; // Say,this is my object
Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();
Schema.SObjectType leadSchema = schemaMap.get(type);
Map<String, Schema.SObjectField> fieldMap = leadSchema.getDescribe().fields.getMap();
for (String fieldName: fieldMap.keySet())
{
String mylabel;
//It provides to get the object fields label.
mylabel = fieldMap.get(fieldName).getDescribe().getLabel();
Schema.DisplayType myType=fieldMap.get(fieldName).getDescribe().getType();
if (myType == Schema.DisplayType.BOOLEAN)
{
if(fieldName.endsWith('__c'))
{
str='\'{!'+type+'.'+fieldName+'}\'';
}
}
}
chk.expressions.value=str;
return chk;
}
Above is my code in which I am trying to the string str as a expression value to checkbox. As I am trying to do this, I am getting the error
"System.VisualforceException: Value assigned to expression field is not valid for <apex:inputCheckbox value>"
Kindly help me out.

Only Boolean values(true/false) can be assigned to fields with ckeckbox type. You need to decide when to set true/false value or you can chane the field type to text.
I want to assign the string as an expression value to checkbox like
chk.expressions.value =str '{!FieldObject__c.Chkbox__c}'; where str contains the value of '{!FieldObject__c.Chkbox__c}'.And for this, I am trying to assign by writing below code:-chk.expressions.value=str; ,but its giving me an error.
how should I assign?
In the code we had assign some value to a string like str='\'{!'+type+'.'+fieldName+'}\'';
Now in "str" we would have the following value: '{!FieldObject__c.Chkbox__c}'. As this is to dynamically set a field name that would be displayed in a VF page. So till here its fine, but when I assign it to
Component.Apex.InputCheckbox chk.expression.value= str;
This is where we experience an error.

You are getting error because of field type mismatch. I can suggest you two things:
1) Convert str to boolean if it is true or false.
2) If str is not true or false the by using IF condition set the value of input checkbox:
if(str="abc")
{
Component.Apex.InputCheckbox chk.expression.value= true;
}
else
Component.Apex.InputCheckbox chk.expression.value= false;
