I don't know where we can use import keyword in C#. Might be you are developing your application VB rather than C# then you are at wrong place. Place correct forum for this.
Again verify those dll should present in your application.
Add these dll to your project then import where you want to use them
Thanks and Regards

Imports statement is used to import namespaces in VB.NET. I think Using is the equivalent in C#.NET.

protected void Menus_MenuItemClick(object sender, EventArgs e)
{
//string x=(string) e.Item.Value;
MenuItemCollection m = new MenuItemCollection();
//System.Web.UI.WebControls.MenuEventArgs x = e.ToString();
}
i want to know which item of the menu is click .
please let me know .

The 2nd argument for the event handler should be of type MenuEventArgs. You can reference the selected item from the information exposed by this type.

Hi i have doubt regarding interfaces...
Suppose in my project i have one interface with 30 methods...
I used this interface in many classes through out the application..
if i suddenly added another method in this interface... i need to change all the files through out the application...
Is there any alternative for this? If i change any modification in interface...shall i need to change in all files..?
Please give reply if any body knows the result..
Thanking you

Yes. When a class implements an interface, it should contain all the methods written inside interface. That says a change in interface will affect all it's implemented classes.

But if interface contains 100 methods means, we used this in many of the classes in the big application, we didn't remember where we implemented this. At that time, any changes to interface...what to do?
any alternative method for this?
G. Satish

That's the reason why interface should not have many methods instead you can break up these methods in many interfaces depending on the similar functionality this could be the one of the reasons why you can implement more than one interface in C#,
Creating one more interface could be alternative solution now as you made really big mistake while designing your application.
It's my view comments are accepted 
Thanks and Regards

 100 methods in an interface ? It doesn't sound like a good design.
|
|
|
|

As others have already said, 100 methods in an interface = design problems.
Having said that, the way around having to implement the method in every derived class is to start with an abstract class rather than an interface. This can provide default behaviour for a newly added method which only needs to be overriden in classes where you want to vary this default behaviour.

|
|
|

My searches yield a myriad of mash-ups that provide my required behaviour of a three column, server control, drop-down. Could anyone please recommend a tried and trusted solution for me?

i am having an image button and i need the click event of the image button to fire but postback should be prevented,is it possible.I tried several methods but didn't worked for me.I even replaced the image button with a image control and used javascript,but still it didn't worked for me.
My requirement is that on the image button click i want to make another web control visible but i need to prevent postback once the click event is fired.
Can any one help?
Thanks in advance

why don't you use image html instead of asp:imagebutton ?
on image html you can create onclick or onclientclick eventhandler to fire your method that will show your control.
hope it helps

i have tried with html control too but didn't worked for me.

Nope. As it is a server-side control, it would Postback.

You can do it using JavaScript. But do not set the Visible Property of the Web Control to false. If you set it, the page would not render that control. So, you will not able to find the control using JavaScript. Use Style property to set the visibility/block. Then write your code to make it visible/hidden

i want to hide an asp:menu,how can that be done using style property?
|
|
|
|
|
ASP.NET render menu control as HTML table. So you can find this element and change visibility using JS.
|
|
|
|

Call this function on event ONClienClick of image button.Menu1 is the ID of menu.
function MakeVisible()<br />
{<br />
var menu=document.getElementById('Menu1');<br />
menu.style.display='none';<br />
return false;<br />
}
html view for image button as below.
<asp:ImageButton ID="ImageButton1" runat="server" OnClientClick="return MakeVisible()" />
For making visible,then give,
menu.style.display=block;

Hi all,
I have developed a web application where there exists some data input pages. In those pages there exists a grid view below some text, drop down and other web controls. I need to display a msg if the user changes some thing in the page or worte in a textbox etc.. Any change made. I need to alert the user that changes has been made and give him the choice to save or not by display yes/no msg.
Any ideas how to do that?
thanks

You can do it by JavaScript itself.
var isDirty = false;
function SetControlChanged(){
isDirty = true;
}
function IsControlChanged(){
if (isDirty){
alert('You have changed some values');
}
return (!isDirty)
}
Call the SetControlChanged() function in all the control's onchange events.
Finally call the IsControlChanged() function to check the status.
