Web Forms :: RegularExpressionValidator To Prevent Numeric Entry Not Working

Jan 9, 2011

I have a 'City' TextBox on one of my web pages but people from many European countries sometimes prefix the city name with the postcode instead of putting it in my dedicated 'Postcode/ZIP' TextBox. I have therefore just added a new RegularExpressionValidator to this TextBox. Its purpose is to prevent the user from entering any numeric characters but allow everything else. After browsing for a suitable regex (I am not a regex expert), I found the following code that was claimed to do what I want.


Unfortunately, the RegularExpressionValidator does not work as expected. Instead of just rejecting numeric characters it appears to reject everything! Where might I be going wrong?

DataSource Controls :: Numeric Fields / Display 4 Digits After The Decimal?

Feb 23, 2010

I currently have a numeric field as numeric(5,2) which has 2 digits after the decimal. Now I need to be able to display 4 digits after the decimal. But if I change the field to (7,4) then it places 2 zeros after the last numbers. For example: 1.32 changes to 1.3200.

But some records will have exactly 4 numbers after the decimal such as : 2.4375.

My issue is I don't want all the data to have 4 numbers after the decimal. I don't think there is another data type that will allow this.

SQL Server :: Relationship Which Allows NULL Entry / Error 'FK_Table_Contracts_Table2_PONo' On Table 'Table_Contracts'?

Nov 29, 2010

I have two tables as below.

I tried to establish a relation between two tables in such a way that Table_Contracts will still accept NULL values for [PO_No], but [PO_No] on TableContract will be automatically updated when [PO_No] on Table2_PONo changed. Moreover, if you want to delete a record on Table2_PONo, it needs to be stopped if there is a related data in Table_Contracts.

I set a relation with these parameters:

Check existing data on creation or re-enabling>

Enforce for replication>

Enforce foreign key constraint>

Delete Rule>
No Action

Update Rule>

I got this error

Introducing FOREIGN KEY constraint 'FK_Table_Contracts_Table2_PONo' on table 'Table_Contracts' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.

(primary key)
(accepts null values)
