How to set focus on first textbox of the page

Below I have given the complete sample code where the cursor will be placed on first textbox when the page loads.

Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title>Ashish's Blog</title>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            $('form input:text:enabled:first').focus();
        }); 
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server" />
 
    <asp:TextBox ID="TextBox2" runat="server" />
 
    <asp:TextBox ID="TextBox3" runat="server" />
 
    <asp:TextBox ID="TextBox4" runat="server" />
 
    </form>
</body>
</html>

UPDATE:

If you first textbox is disabled

$(document).ready(function() {
    $('input[type=text]:enabled:first').focus();
});

If you first textbox is not visible

$(document).ready(function() {
    $('input[type=text]:visible:first').focus();
});

Thanks.

Read Excel file using c#.Net

In this article, I am going to show how to read Excel file using c#. To achieve that we are going to use
Excel Data Reader (http://exceldatareader.codeplex.com/) DLL.
To get Excel Data Reader DLL to your project use NuGet
readexcel
Code:

public void BtnUploadClick(object sender, EventArgs e)
        {
            string filePath = string.Empty;
            uploadPath = Server.MapPath("~/Excel/");            
                if (FileUpload1.HasFile)
                {
                    String fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();
                    String validExt = sAllowedExt;
                    if (validExt.IndexOf("," + fileExtension + ",") != -1)
                    { 
                        if (FileUpload1.FileBytes.Length <= maxsize)
                        {
                            filePath = uploadPath + FileUpload1.FileName; 
                            FileUpload1.PostedFile.SaveAs(filePath); 
                            Response.Write("File uploaded successfully.");
 
                            FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
                            IExcelDataReader excelReader;
                            if (filePath.Contains(".xlsx"))
                            {
                                //2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
                                excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
 
                            }  //...
                            else

                                //1. Reading from a binary Excel file ('97-2003 format; *.xls)
                                excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
                            } //...
                            //3. DataSet - The result of each spreadsheet will be created in the result.Tables
                            //DataSet result = excelReader.AsDataSet();
                            //...
                            //4. DataSet - Create column names from first row
                            excelReader.IsFirstRowAsColumnNames = true;
                            DataSet result = excelReader.AsDataSet();
                            //5. Data Reader methods
                            //foreach (DataRow item in result.Tables[0].Rows)

                            GridView1.DataSource = result;
                            GridView1.DataBind();
                        }

Import XML file to Database Table

In this article, I talked about how to parse XML or import XML to SQL Server Database Table.
XML File:

<br />
<?xml version="1.0"?><br />
<Orders><br />
<Order OrderNumber="99503" OrderDate="2013-10-20"><br />
  <Address Type="Shipping"><br />
    <Name>Ellen Adams</Name><br />
    <Street>123 Maple Street</Street><br />
    <City>Mill Valley</City><br />
    <State>CA</State><br />
    <Zip>10999</Zip><br />
    <Country>USA</Country><br />
  </Address><br />
  <Address Type="Billing"><br />
    <Name>Tai Yee</Name><br />
    <Street>8 Oak Avenue</Street><br />
    <City>Old Town</City><br />
    <State>PA</State><br />
    <Zip>95819</Zip><br />
    <Country>USA</Country><br />
  </Address><br />
  <DeliveryNotes>Please leave packages in shed by driveway.</DeliveryNotes><br />
  <Items><br />
    <Item PartNumber="872-AA"><br />
      <ProductName>Lawnmower</ProductName><br />
      <Quantity>1</Quantity><br />
      <USPrice>148.95</USPrice><br />
      <Comment>Confirm this is electric</Comment><br />
    </Item><br />
    <Item PartNumber="926-AA"><br />
      <ProductName>Baby Monitor</ProductName><br />
      <Quantity>2</Quantity><br />
      <USPrice>39.98</USPrice><br />
      <ShipDate>2013-05-21</ShipDate><br />
    </Item><br />
  </Items><br />
</Order><br />
</Orders><br />

To Query XML File we need to store in to xml variable @MyXML:

<br />
DECLARE @MyXML XML<br />
SET @MyXML = '<?xml version="1.0"?><br />
<Orders><br />
<Order OrderNumber="99503" OrderDate="2013-10-20"><br />
  <Address Type="Shipping"><br />
    <Name>Ellen Adams</Name><br />
    <Street>123 Maple Street</Street><br />
    <City>Mill Valley</City><br />
    <State>CA</State><br />
    <Zip>10999</Zip><br />
    <Country>USA</Country><br />
  </Address><br />
  <Address Type="Billing"><br />
    <Name>Tai Yee</Name><br />
    <Street>8 Oak Avenue</Street><br />
    <City>Old Town</City><br />
    <State>PA</State><br />
    <Zip>95819</Zip><br />
    <Country>USA</Country><br />
  </Address><br />
  <DeliveryNotes>Please leave packages in shed by driveway.</DeliveryNotes><br />
  <Items><br />
    <Item PartNumber="872-AA"><br />
      <ProductName>Lawnmower</ProductName><br />
      <Quantity>1</Quantity><br />
      <USPrice>148.95</USPrice><br />
      <Comment>Confirm this is electric</Comment><br />
    </Item><br />
    <Item PartNumber="926-AA"><br />
      <ProductName>Baby Monitor</ProductName><br />
      <Quantity>2</Quantity><br />
      <USPrice>39.98</USPrice><br />
      <ShipDate>2013-05-21</ShipDate><br />
    </Item><br />
  </Items><br />
</Order><br />
</Orders>'<br />

Now we use SQL query to get Order header from @MyXML:

<br />
SELECT Col.value('@OrderNumber', 'int') AS 'Order',<br />
Col.value('@OrderDate', 'date') AS 'OrderDate',<br />
Col.value('(Address[@Type=''Shipping'']/Name/text())[1]', 'nvarchar(50)') AS 'Shipping_Name',<br />
Col.value('(Address[@Type=''Shipping'']/Street/text())[1]', 'nvarchar(50)') AS 'Shipping_Street',<br />
Col.value('(Address[@Type=''Shipping'']/City/text())[1]', 'nvarchar(50)') AS 'Shipping_City',<br />
Col.value('(Address[@Type=''Shipping'']/State/text())[1]', 'nvarchar(50)') AS 'Shipping_State',<br />
Col.value('(Address[@Type=''Shipping'']/Zip/text())[1]', 'nvarchar(50)') AS 'Shipping_Zip',<br />
Col.value('(Address[@Type=''Shipping'']/Country/text())[1]', 'nvarchar(50)') AS 'Shipping_Country',<br />
Col.value('(Address[@Type=''Billing'']/Name/text())[1]', 'nvarchar(50)') AS 'Billing_Name',<br />
Col.value('(Address[@Type=''Billing'']/Street/text())[1]', 'nvarchar(50)') AS 'Billing_Street',<br />
Col.value('(Address[@Type=''Billing'']/City/text())[1]', 'nvarchar(50)') AS 'Billing_City',<br />
Col.value('(Address[@Type=''Billing'']/State/text())[1]', 'nvarchar(50)') AS 'Billing_State',<br />
Col.value('(Address[@Type=''Billing'']/Zip/text())[1]', 'nvarchar(50)') AS 'Billing_Zip',<br />
Col.value('(Address[@Type=''Billing'']/Country/text())[1]', 'nvarchar(50)') AS 'Billing_Country',<br />
Col.value('(DeliveryNotes/text())[1]', 'nvarchar(250)') AS 'DeliveryNotes'<br />
FROM @MyXML.nodes('/Orders/Order') AS T(Col)<br />

Now we use SQL query to get Order Items from @MyXML:

<br />
SELECT<br />
Col.value('(../../../Order/@OrderNumber)[1]', 'int') AS 'Order',<br />
Col.value('(@PartNumber)[1]', 'nvarchar(50)') AS 'PartNumber' ,<br />
Col.value('(ProductName/text())[1]', 'nvarchar(250)') AS 'ProductName' ,<br />
Col.value('(Quantity/text())[1]', 'int') AS 'Quantity',<br />
Col.value('(USPrice/text())[1]', 'float') AS 'USPrice',<br />
Col.value('(Comment/text())[1]', 'nvarchar(250)') AS 'Comment',<br />
Col.value('(ShipDate/text())[1]', 'date') AS 'ShipDate'<br />
FROM @MyXML.nodes('/Orders/Order/Items/Item') AS T(Col)<br />

Full Code:

<br />
DECLARE @MyXML XML<br />
SET @MyXML = '<?xml version="1.0"?><br />
<Orders><br />

Assign datepicker to runtime/dynamic textboxes in ASP.NET using jQuery

In this short and simple article, we will see how to assign datepicker to runtime textboxes or dynamic textboxes using jQuery in ASP.NET.
Here is code to create three textboxes dynamically (programmatically)
Code behind:

protected void Page_Load(object sender, EventArgs e)
    {
        for (int b = 0; b < 3; b++)
        {
                TextBox txtdate = new TextBox();
                txtdate.ID = "dpicker" + b.ToString();
                txtdate.CssClass = "date";   // class date
                 PlaceHolder1.Controls.Add(txtdate);
            }
    }
&#91;/code&#93;
Here we created three textbox programmatically and assigned <strong>date</strong> to CssClass property of textbox. Now we going to use jQuery UI datepicker plugin to this created textbox class. 

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
   <link type="text/css" rel="Stylesheet" href="http://ajax.microsoft.com/ajax/jquery.ui/1.8.6/themes/smoothness/jquery-ui.css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" >
</script>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.ui/1.8.6/jquery-ui.min.js" >
</script>
<script type="text/javascript">
    $(function () {
        $(".date").datepicker();
    });
</script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
               <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
    </div>
    </form>
</body>
</html>

For more information about Datepicker, have a look my this article.
Thanks.
