FIXED HEADER AND FOOTER IN MASTER PAGE-WITHOUT REFRESH ON MENU CLICK

Hi,
On each menu or sub-menu-item click,the full page ie header,content placeholder and footer are refreshing.Need help.....

Suggest some url.or sample .net website where i can refer the code.

I had tried placing header and footer as seperate user control.But it failed on each menu item click or sub-menu item click.

Using Iframe makes peformance slower.

Thanks

That sounds like the proper behavior to me. Every button / hyperlink click regardless of being on a master page, or within a webform placeholder is going to generate a postback to the server.

If you want to use a button or hyperlink and not generate a complete postback, then you have to use Javascript, to SHOW / HIDE a control or object.

So you add onClientClick to the control object, and that will fire before a postback is generated.

onClientlick="return false;" will return false and cancel the next action.

return true will proceed to the next action.

HI,

1) you need to create one class library project for VB.
2) add your VBClass in that project.
3) build VB project and add DLL file into CSProject.
4) Add reference in your CSClass.
5) use VB functions Smile | :)

Thanks

I tried that years ago and it didn't work. Can't mix vb and csharp together in the same project. When you publish or run the project, the app_code folder gets compiled into a single or multiple dll's, not sure which but they don't mix.

It's kind of like having webforms with a mixture of cs and vb code behind pages.

You need to rewrite one of them if you want to keep them in the App_Code.

Sounds like your not finished.

Did you setup your database and table, and enter a user and password in it.

I remember seeing a complete MS kit, in which you can download a starter program that already has all that going, and it sets up your sql server as well, so you get instant gratification within about an half hour.

I wasn't able to find it, looks like it was replaced with something even easier to use and setup.

[^]

I don't recommend that you install it, but take a look around. I think you should fix your issue first. But figuring out whats wrong is a 3 step approach.

1. Create a user and password in your table.

2. Write a program to create users and passwords.

3. Write a program for the users to login to.

4. Program your pre-made control to login and test it.

if it's the second file, you need to release the first file.

fileInfo = NULL;

Always wrap your code in "Pre" tag, because it will give better readability and accessibility.
