When I was trying to access my connection string from class file using below code string con = ConfigurationSettings.ConnectionStrings["Conn"].ConnectionString;

Avoid re-post on refresh
When a user presses the Browser's Refresh button (Or F5/Ctrl+R etc.) the browser resends the last request data to the server.This action causes an Unexpected Re-Post action (if there was one).In some cases, it can be very problematic (For example, in shopping website when the user clicks on "Add to Cart" button and then presses the Refresh button - the item will be added twice !!!)
SolutionWe will store a unique code (in my case Guid) on both client and server and compare them on every request action. If the two codes are not equal, the action will be canceled and the page will reload ('GET' method).

?? Operator
Starting with how to assign null value type to non-nullable type.Nullable types are declared in one of two ways:System.Nullable<T> variable
-or-T? variable
Where T can be any value type including struct; it cannot be a reference type.
Examples of Nullable Typesint? i = 10;
double? d1 = 3.14;
bool? flag = null;
char? letter = 'a';
int?[] arr = new int?[10];
Now coming to the main point, ?? operator
One of the best features of C# is the ?? "null coalescing" operator. This provides a nice way to check whether a value is null, and if so return an alternate value.The ?? operator defines the default value to be returned when a nullable type is assigned to a non-nullable type. If you try to assign a nullable type to a non-nullable type without using the ?? operator, you will generate...

Difference between Trigger and Stored Procedure
Stored procedures cannot run automatically, they have to be called explicitly by the user.But triggers are executed automatically when particular event (like insert, update, delete) associated within the database object (like table) gets fired.
Stored procedures can be scheduled through a job to execute on a predefined time, but we can't schedule a trigger.
Stored procedure can accept the parameters from users whereas trigger cannot accept parameters from users.
We can use the transaction statements like begin transaction, commit transaction and rollback inside a stored procedure but we can't use the transaction statements inside a trigger.
A Trigger can call the specific Stored Procedures in it, but the reverse is not tru...
Convert Gridview to Datatable
To copy your Gridview datasource directly into a datatable, without using any loop, one can use BindingSource Class.Below is the example:BindingSource bs = (BindingSource)GridView1.DataSource;
DataTable dt = (DataTable)bs.DataSource;
OR
if (GridView1.HeaderRow != null)
{
for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
{
dt.Columns.Add(GridView1.HeaderRow.Cells[i].Text);
}
}
// add each of the data rows to the table
foreach (GridViewRow row in GridView1.Rows)
{
DataRow dr;
dr = dt.NewRow();
for (int i = 0; i < row.Cells.Count; i++)
{
dr[i] = row.Cells[i].Text.Replace(" ","");
}
dt.Rows.Add(dr);
}
// add the footer row to the table
if (GridView1.FooterRow...
Get selected value in Checkboxlist
Hello Everybody,
Yesterday I was facing a problem getting the current value of the checkboxlist.
I have tried using the selected value, as I thought that would give me the current value of the checkbox, but it appears to be giving me the first value that is selected all the time.
I have also tried to use the selectedItem property, but that does the same as I would expect, because the property says it get the item with the lowest value.
After searching i came up with the solution which is below...protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
{
string value = string.Empty;
string result = Request.Form["__EVENTTARGET"];
string[] checkedBox = result.Split('$');
int index = int.Parse(checkedBox[checkedBox.Length - 1]);
if (CheckBoxList1.Items[index].Selected)
