hi all
I am developing a web application.
And I have problem with event in UserControl.
i have userControl is search.ascx
With usercontrol search.ascx have three Control is : two DropDownList (ddlCategory and ddlProduct) and Button(search).
in Function Page_Load of search.ascx have function "LoadCategory load all category" for ("ddlCategory"). When user choose category it will Load All Product of category ("ddlProduct") with event ddlCategory_SelectedIndexChanged(). after that user choose product(“ddlProduct”) and finally click button "search".
note: ddlCategory is postback = "true" and event ddlCategory_SelectedIndexChanged()
ddlProduct is postback = "false" and event SelectedIndexChanged = “”
I have a page Default.aspx and in Page_Load
UserControl ucl = new UserControl();
divControlLeft.Controls.Clear();
ucl = (UserControl)LoadControl("search.ascx ");
divControlLeft.Controls.Add(ucl);
but have problem:
so it don't get SelectedValue "ddlProduct".and into usercontrol it run to Load_page() function then to ddlCategory_SelectedIndexChanged() finally btlSearch_ServerClick().
"i dont understand why it run to ddlCategory_SelectedIndexChanged() ?????" when i click button search . And the ddlCategory and ddlProduct dont store value when i click search button ???
How can I get value in ddlProduct and don’t run event ddlCategory_SelectedIndexChanged() in search.ascx UserControl ????
Could u show me ???
If i drag usercontrol to “desgin” default.aspx page it run ok !!! it dont run to ddlCategory_SelectedIndexChanged() function when i click to search button and it get value ddlProduct is successful.

Hi,
Here u r creating an instance of ur usercontrol in page_load of default.aspx page so it will be created everytime your aspx is loaded. Process of creation of new instance of usercontrol causes page_load of usercontrol to execute hence your ddlcategory will load data again in itself hence it wont preserve its value and so ddlproduct doesnt.
The better way it to drang and drop your usercontrol in page then use it.
of the second way is use if(!ispostback) block arount your code in page_load.
I am not sure the second way will work perfectly but the first option will 100% work.
I hope this will help you.
Thanks and Regards,

hi Chetan Ranpariya
Thank reply to me
But i have three usercontrol and search is one of three usercontrol therefore i have to use dynamic usercontrol with code behind
So when i use if(!ispostback) with usercontrol search isn't feasible
Because When u choose every usercontrol if u user if(!ispostback) it dont run the function on page_load() ex: function loadallcategory on the usercontrol search.ascx
Could u show me any way solve this problem.

Hi,
I am using (((Login)LoginView1.FindControl("Login1")).FindControl("rememberCheckBox")) but I don't know which is exact place to check whether checkbox is checked or not? In other words under which even I should place this? I don't have Page_Load as it is in Masterpage
|

Ya I know I am using following code.
((CheckBox)((Login)LoginView1.FindControl("Login1")).FindControl("rememberCheckBox")).Checked
I have a checkbox named "RememberMe" what I need is that when user press button to get login system should check checkbox. If checkbox is checked then write a cookie with username and passwod otherwise do nothing so what could be its solution?
Waiting for reply.
Kind Regards,

Hi,
Very simple before signing out check which type of user is selected then based on that redirect to appropriate page.
If usertype = admin then
response.redirect("adminlogin.aspx")
else
response.redirect("userlogin.aspx")
end if
Hope that would do for you.

Why do you need two logins ? An admin should be an admin by virtue of their privileges, based on their username/password. Also, putting the message on the URL is a bad idea.

I can't see any way to get past the first page. The error has nothing to do with the details you enter, its a problem with the SQL Server connection your application is trying to open (as is evident from the error message)

|
|
|
now try again to enter the site www.jobsfreejobs.com

No-one can tell you the problem by looking at the site, we need to look at code. If you want to advertise your job site, talk to the site admin about buying advertising. If you need help with your code, post it here and we can help you.
