OK.I've already done all Session variable checking for authentication to all of every .aspx pages(I don't use <authentication> of Web.config).

The point is that it works fine until i clicked log out link and cleared all Session i used and redirect to LogIn.aspx and then i type the url directly "http://localhost/default.aspx" to browser .The result is I still can acces this page althrough i've logged it out.

Next i try to check why Page_Load of default.aspx don't check authentication
So i beaked this line in Page_load

... Page_Load(....)
{
if(Session["Authen"]=="0"||Session["Authen"]==null)
   Response.Redirect("LogIn.aspx");
else
   //...

}

Then I test it, I log in then log out.Now the current page was redirect to LogIn.aspx.After that i type url of default.aspx to browser.I can access default.aspx as i still log in.It's not even enter the Page_Load function that i've breaked.Why? Is it about Session cache?

what datatype you are using in DB.
Use Datatype as 'Nvarchar'
And while sending that data through any procedure, there also use datatype as Nvarchar.

Nvarchar datatype has length -- 4000.

Hope it will help you.

In gridview you can do it following manner:

On Rowdatabound:

protected void ParentGridView_RowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
  if (e.Row.RowType == DataControlRowType.DataRow)<br />
     {<br />
      GridView ChildGridView = (GridView)e.Row.FindControl("NestedGridView");<br />
     }<br />
}

Here "NestedGridView" is the gridview Control have created in aspx file.
And "ChildGridView" object which you have created to play in .cs file.

Hope This will help you.

Encrypting and Decrypting Configuration Sections

In this article: "Encrypting and Decrypting Configuration Sections [^]" we discover how to use Aspnet_regiis.exe to Encrypting and Decrypting web.config sections.

My problem is that it works using a machine-specific key, so I cannot encrypt the web.config and then send to a remote server (like in shared hosts, when the website is hosted in a shared ISP).

I remember some time ago that I saw a good tool where I inform the password in a Windows Forms GUI, that returns the base64 encrypted password. So, I can use a simple function to decrypt from web.config im my Asp.net code.

I can't find that tool anymore. I don't remember neither the site or the name.. Can someone help me?

I need to display a Treeview control with nodes representing values that can be outdated. I want to display the outdated nodes in red, and the rest of the nodes in light green. I guess the object TreeNode must have a Style property or so, but I can't find it. Please, I would greatly appreciate any suggestions!

How many items are there in your drop downlist ?
Even you have 100 or 200 it should not give any problem

Its waste by loading 16,000 items in the Dropdown list just laod all the contents in the DB abd activate it using the Ajax or atlas to the front end.

Newbie: How do I get Record Count from paged GridView with SqlDataSource data source?

Hello All,

I am a newbie to .NET and SQL...have been hiding under the rock of Ph.D. studies...

I have a ASP.NET web page with a GridView control on it and I want to display the total number of records in the whole table. I am a newbie to .NET, Databases, SQL, and ASP.NET.

I've seen this posted elsewhere, however I can't make sense of the answers because they assume familiarity with databases. I don't know my DataSet from my DataView from my elbow. If anyone would be willing to give me a hint, I would be greatly appreciative.

Thanks so much.

Sincerely Yours,

Crystal reports toolbar button not working

Richard Jones15-Oct-07 8:40

My crystal report viewer control has the toolbar enabled, and I fixed it so the images now display.

When I click the Export or Print buttons, nothing happens. I don't see anywhere to override their function either.
I notice many sample report pages contain a separate Print button which handles this. I'd avoid this if possible.
