How to replace carriage return and line feed in a SQL server varchar field


I have been facing an issue while importing some data from SQL to CSV file. In one of my SQL fields user entered Enter Key or Line feed, because of that my exported CSV file was not in good format. Rows were broken in between. So I started searching for a solution to replace carriage return and line feed and finally accomplished by writing below query.

SELECT replace ( replace(Col1, char(10),''), char(13), '') as [Column 1] FROM  Test

In the above code "col1" is the column name where you have enter key or line feed and "Test" is the table name.

After using this query I was able to export the data to CSV with proper formatting as I required.

I hope this query may help you also.

How to validate RadioButton using C#


Validating radio button in ASP.NET is not very tough but new programmers always get confused about this and ask the questions in forum for the help. So I thought I will write a simple article related to this topic.

Here I am going to use JavaScript to validate the RadioButton.

First we will create the RadioButton.

<asp:Label ID="Label1" text ="Please select one of your favorite fruits" runat="server"></asp:Label>

<asp:RadioButtonList ID="radiobutton1" runat="server">

<asp:ListItem Text="A.Apples">Apple</asp:ListItem>

<asp:ListItem Text="B.Banana">Banana</asp:ListItem>

<asp:ListItem Text="c.cherry">Orange</asp:ListItem>

<asp:ListItem Text="D.Dates">Grapes</asp:ListItem> </asp:RadioButtonList>

<asp:Button ID="btnSubmit" runat="server" onclick="btnSubmit_Click"

Text="Submit" />

If you look at the above code I have created a RadioButtonList with 4 RadioButtons and a Button.

Now we will write the JavaScript to validate the RadioButtonList

<script type="text/javascript">

function rdValidate()


var rd = document.getElementsByName('radiobutton1')

for (var i = 0; i < rd.length; i++)


if (rd[i].checked)


return true;



alert("Please select an option");

return false;



Next we will call the JavaScript function to validate the RadioButtonList on Button Click Event.

protected void btnSubmit_Click(object sender, EventArgs e)


ClientScript.RegisterStartupScript(GetType(), "Alert", "<script>rdValidate();</script>");


That’s it. Now you can run your application and click on the button click event without selecting the RadioButton. You will get the alert message like in below screen print.
