Variable Hides A Variable In An Enclosing Block Error

May 14, 2010

have a look at this simple code snippet

[Code]....

Here second declaration of x gives error that "variable 'x' hides a variable in an enclosing block. I wonder why this error is not given for second 'i' variable declared in second for loop?

Since i am declaring second x in a separate for block, why this error is given for variable second x ?

To Reach A Variable From A Different Code-block Expression Than The Block Where The Variable Was Declared ?

Oct 25, 2010

I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.

So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?
<p>
<%for (int i = 0; i < 30; i++)
{

Forms Data Controls :: Nested GridView Control Returns "Object Variable Or With Block Variable Not Set" ?

Oct 20, 2010

Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.

The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....

Object variable or With block variable not set.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object variable or With block variable not set.

Source Error:

Line 118: If e.Row.RowType = DataControlRowType.DataRow Then
Line 119: Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)
Line 120: If Not e.Row.DataItem("Status_ID") Is Nothing Then
Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
Line 122: End If

I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:

*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)

*If Not localLblItemReference Is Nothing Then

******************************************************************************************

To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.

In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:

Exception Details: System.NullReferenceException: Object variable or With block variable not set.

C# - Declare And Create Variable In Code Behind?

Jul 27, 2010

Here are 3 scenarios:

namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
if (!Page.IsPostBack) v= new Variable();
....
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v = new Variable();
protected void Page_Load(object sender, EventArgs e){
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
v = new Variable();
}
}

When does the variable "v" gets created every time for the 2nd scenario? Is the 2st scenario is equivalent to the 3rd one?

Web Forms :: How To Declare A Global Variable That Can Be Used Within A User

May 15, 2010

I would like know how to declare a global variable that can be used within a user after the user login and before the user logout across all the possible pages.

I need to develop a web application that will connect to 5 different servers depends on the selection of user on what server they wish to connect and after they select a server and login...I will need to keep track the server name in a variable last until the user logout (user may visit various pages but the server name MUST NOT be changed due to other user login into different server). So how can I do it so that other users may select different servers and will keep the server name for each different users.

Let says:-

User A selects Server A and login and User B selects Server B and login at the same time, so how the global variable can handle the needs for each user (User A & B) with different server select?

Is "Session" the only way to fulfill the above? I think of using Application State but it seems that the value stored will be shared by all users and not for a particular user.

State Management :: Looking For A Way to Declare A Global Variable?

May 14, 2010

I'm looking for a way to declare a global variable (so all pages could see) but personal (so if one user puts some value in it, it won't matter to another user or change his value).Sessions and hidden fields won't do. I've tried working with declaring keys in Web.config but unfortunely, the keys values aren't personal, and all users share the same key value.Another way I was thinking was maybe classes, but perhaps there might be an easier solution?

SQL Server :: Using SQL INSERT Command With DataGrid - Must Declare The Scalar Variable Error

Mar 28, 2011

OK, this may be a little difficult to explain, so I will try my best and post the code I currently have.

I have a table with a list of usernames. I have the list of usernames displayed on a page through a GridView. What I am attempting to do is for each username in the column "adminUsernames", I need to insert a set of values in another database table for EACH "adminUsernames" that exists. Example: There are 2 adminUsernames vales in 2 seperate rows. These are "Admin 1" and "Admin 2". For each adminUsername values (Admin 1, Admin 2), I need a row interted in another database table. Maybe the code that I have (that does not work) will help you see what is happening:
