For example – inserting value in the empty gridview:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
 if (e.CommandName == "Insert") {
  TextBox txt  =
    (((Control)e.CommandSource).NamingContainer).FindControl("txtTest") as TextBox;

    //do insert action
 }
}

Another way to do this is by getting EmptyDataTemplate table and its controls:

if (e.CommandName == "Insert")

{
   Table table = (Table)GridView1.Controls[0];
   TextBox txtTest= (TextBox)table.Rows[0].FindControl("txtTest");

   //do insert actions
}

public void dgBoundItems(object sender, DataGridItemEventArgs e) 
{ 
    foreach(TableCell cell in e.Item.Cells) 
    { 
        ///e.Item.DataSetIndex = row 
        ///e.Item.Cells.GetCellIndex(cell) = column
        if (e.Item.Cells.GetCellIndex(cell) == 2 && e.Item.DataSetIndex > 0) 
        {
            ///If the salary is less than 5000 the color must be red. 
            if (Convert.ToInt32(cell.Text.Trim()) < 5000) 
            { 
                cell.ForeColor = Color.Red; 
            } 
        } 
    } 
}

I added what is below to my web.config file:

<httpModules>
<add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax"/>
<add name="ScriptModule" type="Microsoft.Web.Services.ScriptModule"/>
</httpModules>

And I got:

Could not load file or assembly ‘MagicAjax’ or one of its dependencies.
The system cannot find the file specified. (C:\Inetpub\wwwroot\TheTracker\web.config line 48)

The solution I found that worked was adding the MagicAjax assembly to your /bin folder. And that fixed the problem.

Console Applications are command-line oriented applications that allow us to read characters from the console, write characters to the console and are executed in the DOS version. Console Applications are written in code and are supported by the System.Console namespace.

The Try word means “Try to execute this code”. The Catch word means “Catch any errors here”. The ex is a variable, and the type of variable it is an Exception object.

Example

Public Function Delete(ByVal fileName As String) As Boolean
	Try
		File.Delete(String.Format("{0}\{1}", ConfigurationManager.AppSettings("ImageDirectory"), fileName))
		Return True
	Catch ex As Exception
		Return False
	End Try
End Function
