throwing error:
Invalid column name '#Results'.
how to solve it?

Answer 1

If i understand your problem correctly you should first exec dynamic sql before select from temporary table
Alter PROCEDURE sp_Get_CustInfoSerach2
(
#PageIndex INT = 1 ,
#PageSize INT = 10 ,
#RecordCount INT OUTPUT ,
#ColumnName VARCHAR(50)=null ,
#Value VARCHAR(50)=null ,
#ddlValue VARCHAR(50)=null ,
#txtValue VARCHAR(50)=null ,
#status varchar(30)
)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #cmd AS NVARCHAR(max)
If #txtValue IS NULL
Begin
SET #Value = ''''+#ddlValue+ ''''
End
Else
if #ddlValue IS NULL
Begin
SET #Value = ''''+#txtValue+ ''''
End
SET #cmd = 'SELECT ROW_NUMBER() OVER ( ORDER BY C_Register.UserId desc )AS RowNumber,
C_Register.UserId, C_Register.Name, C_Register.UserName, C_Register.Status,
Packages.PackagePeriod, Packages.PackageName, C_Register.ActivationDate,
Receive_Payment.OldExpiryDate, Receive_Payment.Balance, Receive_Payment.PyingAmount,
Receive_Payment.LastPaidDate, C_Register.LastUpdateTime,
Area.AreaName, C_Register.MobNo, Employee.EmpName, C_Register.Address,C_Register.CreatedDate
INTO #Results
FROM C_Register INNER JOIN Receive_Payment ON C_Register.UserId = Receive_Payment.UserId
INNER JOIN Area ON C_Register.AreaId = Area.AreaId
INNER JOIN Employee ON Receive_Payment.EmpId = Employee.EmpId
INNER JOIN Packages ON Receive_Payment.PackageId = Packages.PackageId
where C_Register.AccountExpiry= Receive_Payment.OldExpiryDate And C_Register.Status = '+#status+'And
' + #ColumnName + ' = ' + #Value
/*First Execute above dynamic Sql query */
EXEC(#cmd)
/* From the above execute statemnet the query will executed and temporary table will created on the fly */
SELECT #RecordCount = COUNT(*)
FROM #Results
SELECT * FROM #Results
WHERE RowNumber BETWEEN(#PageIndex -1) * #PageSize + 1 AND(((#PageIndex -1) * #PageSize + 1) + #PageSize) - 1
DROP TABLE #Results

Problem in your query is creation of temp table thats not right way to create temp table inside dynamic query.
But even if you create temp table inside a dynamic query it can be accessed only inside the session of dynamic query. If you try to select the temp outside of dynamic query which is created inside the dynamic query you will get a error saying object doesnot exist.
Since you know the number of columns present in the result of dynamic query you can create the temp table outside of dynamic query and insert the records through dynamic query.
Try changing your procedure like this.
ALTER PROCEDURE Sp_get_custinfoserach2 (#PageIndex INT = 1,
#PageSize INT = 10,
#RecordCount INT output,
#ColumnName VARCHAR(50)=NULL,
#Value VARCHAR(50)=NULL,
#ddlValue VARCHAR(50)=NULL,
#txtValue VARCHAR(50)=NULL,
#status VARCHAR(30))
AS
BEGIN
SET nocount ON;
DECLARE #cmd AS NVARCHAR(max)
IF #txtValue IS NULL
BEGIN
SET #Value = '''' + #ddlValue + ''''
END
ELSE IF #ddlValue IS NULL
BEGIN
SET #Value = '''' + #txtValue + ''''
END
/*create a temp as same structure of your dynamic query select statement*/
CREATE TABLE #result
(
rownum INT,
userid INT,
NAME VARCHAR(100),
username VARCHAR(100),
status VARCHAR(15),
packageperiod VARCHAR(15),
packagename VARCHAR(100),
activationdate DATETIME,
oldexpirydate DATETIME,
balance NUMERIC(22, 4),
pyingamount NUMERIC(22, 4),
lastpaiddate DATETIME,
lastupdatetime DATETIME,
areaname VARCHAR(100),
mobno INT,

createddate DATETIME
)
SET #cmd =
' Insert into #result
SELECT ROW_NUMBER() OVER (ORDER BY C_Register.UserId desc )AS RowNumber,
C_Register.UserId, C_Register.Name, C_Register.UserName,
C_Register.Status, Packages.PackagePeriod, Packages.PackageName,
C_Register.ActivationDate,Receive_Payment.OldExpiryDate,
Receive_Payment.Balance, Receive_Payment.PyingAmount,
Receive_Payment.LastPaidDate, C_Register.LastUpdateTime,
Area.AreaName, C_Register.MobNo, Employee.EmpName,
C_Register.Address,C_Register.CreatedDate
FROM C_Register
INNER JOIN Receive_Payment
ON C_Register.UserId = Receive_Payment.UserId
INNER JOIN Area
ON C_Register.AreaId = Area.AreaId
INNER JOIN Employee
ON Receive_Payment.EmpId = Employee.EmpId
INNER JOIN Packages
ON Receive_Payment.PackageId = Packages.PackageId
where C_Register.AccountExpiry= Receive_Payment.OldExpiryDate And C_Register.Status = ' + #status + ' And ' + #ColumnName + ' = ' + #Value
SELECT #RecordCount = Count(*)
FROM #results
SELECT *
FROM #results
WHERE rownumber BETWEEN( #PageIndex - 1 ) * #PageSize + 1 AND( (
( #PageIndex - 1 ) * #PageSize + 1 ) +
#PageSize ) - 1
DROP TABLE #results
EXEC(#cmd)
END
Note : I have given generic datatypes to temp table columns please change the datetypes according to your schema.
