To validate checkbox list use the CustomValidator  control and set the ClientValidationFunction to the
javascript function. Following is the javascript code.
function ValidateCheckboxList(source, args)
{
var chkcbl_repeat_future= document.getElementById (‘Id of the checkbox list’);
var chkList= chkcbl_repeat_future.getElementsByTagName(“input”);
for(var i=0;i
{
if(chkList[i].checked)
{
args.IsValid = true;
return;
}
}
args.IsValid = false;
}
Here you can download example code

I found the following code is good for doing or resting the validation controls. Now our reset button will be

server control not html input type control.

Dim val As IValidator

For Each val In Validators

val.IsValid = True

Next

This code will reset the all validation controls in the form. Now we will reset our other fields too.

Here is code.

Protected Sub btn_Reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_Reset.Click

Dim val As IValidator

For Each val In Validators

val.IsValid = True

Next

ResetFormControlValues(Me)

End Sub

Private Sub ResetFormControlValues(ByVal parent As Control)

Me.txt_ConfirmTag.Text = “”

Me.txt_Description.Text = “”

Me.txt_RewardAmount.Text = “”

‘For Each c As Control In parent.Controls

If c.Controls.Count > 0 Then

ResetFormControlValues(c)

Else

Select Case (c.GetType().ToString())

Case “System.Web.UI.WebControls.TextBox”

CType(c, TextBox).Text = “”

Case “System.Web.UI.WebControls.CheckBox”

CType(c, CheckBox).Checked = False

Case “System.Web.UI.WebControls.RadioButton”

CType(c, RadioButton).Checked = False

Case “System.Web.UI.WebControls.DropDownList”

CType(c, DropDownList).SelectedIndex = 0

End Select

End If

Next c

End Sub

This script will generate script to insert/update from a source table in one database to an  identical destination table in another database or server.  It can be run for inserts or updates,  and can be run for a single row in insert and update mode, or all rows in a table for insert mode.

Instructions:

1) open script and connect to the source database

2) Change the  variable values to change the output options for the script below (@tab, @statementtype etc)

3) execute the script (best to use text output)

4) copy the script output into a script window, and run on the destination table.

Interview is very important event for any person. A good interview leads to good career if candidate is willing to learn. I always enjoy interview questions and answers series. This is my very humble attempt to write SQL Server 2008 interview questions and answers. SQL Server is very large subject and not everything is usually asked in interview. In interview what matters the most is conceptual knowledge and learning attitude.
