StringCollection vs ArrayList

ArrayList is Obsolete.

ArrayList of strings, better or StringCollection .

Cost of Casting occurs in both cases when accessing item from both collections.

ArrayList we need to implement toString(), StringCollection Wrapper implements this method internally.

Client-side Paging for DataGrids

http://msdn.microsoft.com/en-us/magazine/cc164022.aspx

Example to use js array to bind a GridView

Using Ajax Data Controls we can do this.

here is the sample

"<" AjaxData:Gridview ID="ImagesList" runat="server" Visible=True ">"

"<"/AjaxData:GridViewBoundColumn>
""<"/AjaxData:GridViewBoundColumn">"

"<"/AjaxData:Gridview">"


function pageLoad(sender, e)
{
var data = new Array();
data[0] = { Id: 1, Name: "Scott" };
data[1] = { Id: 2, Name: "Tiger" };
data[2] = { Id: 3, Name: "Zeke" };
data[3] = { Id: 3, Name: "Joe" };
adc.set_dataSource(data);
adc.dataBind();
}

AJAX GridView paging Cutting Edge

C# Code copy and paste....


protected void bindGridView()
{
string connectionString = ConfigurationManager.ConnectionStrings["SqlConnectionString"].ToString();
SqlConnection sqlCon = new SqlConnection(connectionString);


try
{
SqlCommand sqlCmd = new SqlCommand("select * from products", sqlCon);
sqlCmd.CommandType = CommandType.Text;
SqlDataAdapter sqlAdp = new SqlDataAdapter(sqlCmd);
DataSet myDataSet = new DataSet();
sqlAdp.Fill(myDataSet);


// Delay the current Thread to display
// the UpdateProgress status
// Not required in real projects
System.Threading.Thread.Sleep(4000);


GridView1.DataSource = myDataSet;
GridView1.DataBind();
}
catch (Exception ex)
{
lblErrorMsg.Text = ex.Message;
}
}


protected void btnLoadData_Click(object sender, EventArgs e)
{
bindGridView();
}


protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bindGridView();
}


Note: i was trying to execute this using PageIndex Changed . instead use PageIndexChanging.. paging works fine.

ajax for beginners

I dont know why some one has named it ajax. but in 2003 i have written an application using xmlhttp object . which was used to communicate with xml webservice to get a resultset. and display the results in excel.

i will show the example what i have done in my next post.

motivation is share mere yaar " share the knowledge" .

ajax is asynchronous call made using javascript either to the .net web application or webservice.

we need following minumum javascript methods to make a call.

/*---- Get xml http object ---*/

function GetXmlHttpObject() {
var xmlHttp = null;
try {
// Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest();
}
catch (e) {
// Internet Explorer
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}

/*---------------------*/



function stateChanged() {
if (xmlHttp.readyState == 4) {
....Write your code to assign response to the html dom element.
}
}


here is the java script funtino can be called on each key up on text box
following function gets the employee details from getEmployee.aspx page.

function showEmployee(str) {
xmlHttp = GetXmlHttpObject();
if (xmlHttp == null) {
alert("Your browser does not support AJAX!");
return;
}
var url = "getEmployee.aspx";
url = url + "?q=" + str;
url = url + "&sid=" + Math.random();
xmlHttp.onreadystatechange = stateChanged;
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}

any questions please drop a question.

thanks
