Do you want to get selected Datalist rows values on SelectedChanged event of dropDownList?

Where is selectedChanged Event of dropDownlist?

FInd dropdownlist control on ItemCreated event of datalist and Create EventHandler event to fire SelectedChanged Event

May be possible that you are binding Datalist on Every postback.
Check out

<br />
if(!Ispostback)<br />
{<br />
//BindDataList<br />
}

Hi All,
How to disable all controls of the aspx page, when some condition occus?

I have done this thing manually. Like taking each and every control of page and setting it's propery as true.

<br />
if(status>=1)<br />
				{<br />
						txt_apply_for.Enabled = false;<br />
						input_type_repayment.Enabled = false;<br />
						input_loan_package.Enabled = false;<br />
						input_first_home_buyer.Enabled = false;<br />
						input_company_application.Enabled = false;<br />
						input_interest_rate.Enabled = false;<br />
}<br />
else<br />
{<br />
txt_apply_for.Enabled = true;<br />
					input_type_repayment.Enabled = true;<br />
					input_loan_package.Enabled = true;<br />
					input_first_home_buyer.Enabled = true;<br />
					input_company_application.Enabled = true;<br />
					input_interest_rate.Enabled = true;<br />
}<br />

But it is very tough when controls are more. Is there any other way or solution for this? Thank You

Keep Smiling........... Smile | :)

Read my reply, his code won't really work. You need a recursive function, and you definately do not need to do all that ugly casting.

Wow.

You're on the right track, and yet so far from it. The base class, Control, has the enabled property. The casting you're doing is totally superfluous, and makes the code messy.

Also, don't use 'is' and then cast. Use 'as' and use the result.

finally, the method needs to be recursive for it to work across the page.

Something Like this...

Private Sub DisableControls(ByVal c As Control)
   If TypeOf c Is WebControl Then
      CType(c, WebControl).Enabled = False
   End If
   For Each child As Control In c.Controls
      DisableControls(child)
   Next
End Sub

Put all the controls inside a container control(panel) and pass the Container Control as a parameter to this function. This will Disable all the server controls that is inside the Container Control.

Private Sub DisableControls(ByVal c As Control, ByVal status As Boolean)
    For Each child As Control In c.Controls
        If TypeOf c Is WebControl Then
           CType(c, WebControl).Enabled = status
        End If
    Next
End Sub

What on earth is your problem ? You've asked this four times now, and you have got more than four answers. If you're incapable of understanding the answers, reply to the people who have answered you. What you're doing is plain rude. The answers will not change, no matter how often you ask.

Tell me one thing paren1 and parent2 are predefine node or it create dynamically

When you add any node then check parent node of the node: if it is Root node then allow to add other deny.
Like:

Root
parent1
child1
parent2

suppose if user want to add node in child1 then check parent node of the child1 that is parent1 not it Root. so it will deny it.

if user want to add node in parent1 then check parent node of parent1 is Root that is Root so it will be allow.
