Hi All,
     We can create a data table dynamically. That is we can get particular columns from the dataset where as the dataset having all columns/many columns. From that dataset we can get our necessary columns.

private DataTable GetInitalTable(DataSet ds)


{
//Instatiate the data table
DataTable dt = new DataTable();

//Initialise the column names
dt.Columns.Add("Id");
dt.Columns.Add("firstname");

//loop
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)

{
//Assign/Adding the Rows from dataset
dt.Rows.Add(ds.Tables[0].Rows[i]["Id"], ds.Tables[0].Rows[i]["firstname"]);

}
// Return the data table!
return dt;

}
 
 
The input is the whole dataset records. But the we can get out put only with two columns as per the above example...
 
 
Happy Coding!!!!!!!

Hi All,

 we are all know how to connect the SQL Database from our C#. I am just given the syntax of Connection String which is used to connect the SQL.

Herewith I have explained and given the code for multiple file upload using jquery.
We know all the normal upload functionality. But someone of us wants the multiple file upload in .NET. Here jquery makes that very easy.
We just use the same asp:fileupload control. If you want to accept only jpg,png only you no need to go for a customvalidator tocheck the file extension. You just add the accept="jpg|png". Thats it. It allows only files which has the extension of above.
Ok let us see the code below,

HEAD SECTION:
<script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script>
<script src="Scripts/jquery.MultiFile.js" type="text/javascript"></script>
 
BODY TAG:
<div>

<asp:FileUpload ID="fupImage" runat="server" class="multi" accept="" />
<br />
<asp:Button ID="btnUpload" runat="server" Text="Upload All" OnClick="btnUpload_Click" />
</div>

Thats it about in the UI page(aspx).
Let us see the code behind page,

the following code should be inside in the upload button event,

try

{
// Get the HttpFileCollection
HttpFileCollection hfc = Request.Files;
Guid newid = new Guid();
newid = System.Guid.NewGuid();
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
hpf.SaveAs(Server.MapPath("Files") + "\\" +
System.IO.Path.GetFileName(newid + hpf.FileName));
Response.Write("Uploaded Successfully <br/>");
}
}
}
catch (Exception ex)
{
// ERROR OCCURED
}

Hi All,

     Here you can get the idea about the expanding of div inside an master page or any other pages. This has some animation. That is if you click on the Login Link then the below login tab will be open with some animation.
    Here you may find the style used for this sample in style tag. Please have a look at the following coding,

This should be inside the head tag.

<script src="js/jquery-1.2.6.min.js" type="text/javascript"></script>
<style type="text/css" media="screen">
#expand
{
display: none;
background-color: Transparent;
position: absolute;
z-index: 100; /* padding: 16px;
background-color: Blue;
z-index: 1000;
width:350px; */
}

.expandInfo
{
background-color: Transparent;
margin: 0;
padding: 0px;
}
</style>
 

<script type="text/javascript">
<!--
$(function () {
$('.expandInfo a').click(function () {
$('#expand').slideToggle(1500);
return false;
});
})
//-->
</script>

<script type="text/javascript">
<!--
$(function () {
$('.expandInfoClose a').click(function () {
$('#expand').slideToggle(1500);
return false;
});
})
//-->
</script>
 
Then the body content may be as follows,
 
<div class="bg">
<p class="expandInfo">
<a href="#home" title="Login" class="login" style="width: 100px; height: 100px;">Login</a>
</p><br />
<br />
<div id="expand"><table cellpadding="0" cellspacing="0" class="loginbg">
<tr>
<td valign="top" style="padding-left: 30px">
<div style="float: right; padding-right: 10px">
<p class="expandInfoClose">
<a href="#home" title="Close">
<asp:Image runat="server" ID="imgcloselog" SkinID="imgLoginBoxClose" />
</a>
</p>
</div>
<asp:Panel runat="server" ID="pnlLoginMaster" DefaultButton="btnLogin">
<table cellpadding="4" cellspacing="4" align="left" style="margin-top: 60px;">
<tr>
<td align="left" valign="top">
<%--// CONTENTS--%>

</table>
</asp:Panel>

Hi Guys,

     Many of them in need of getting the Top 1 or Top 10 records from a Dataset without going to SQL query. It is possible to do from Code Behind. I have given the code below,
     The below code is to get single record from a Dataset. Also I have given for getting 8 records at Green Color.

  public DataSet GetTopTen(DataSet ds)
{
try
{
DataView dv = ds.Tables[0].DefaultView;
dv.Sort = "ModifiedDatetime DESC";
DataSet dss = new DataSet();
DataTable dt = dv.Table.Clone();
dss.Tables.Add(dt);

// This is To get 8 records
//int counter = 0;
//if (dv.Count > 8)
// counter = 8;
//else
// counter = dv.Count;
//for (int i = 0; i < counter; i++)
//{
// DataRow dv = dv[i].Row;
// dss.Tables[0].ImportRow(dv);
//}

// This is for Getting only one Record
DataRow dv = dv[0].Row;
dss.Tables[0].ImportRow(dv);
dss.AcceptChanges();
return (dss);
}

catch (Exception e)
{
throw e;
}
}

Hope this will help you Guys.... Please touch with this blog... I will update regularly....
