i passed something like this. it works now.

$.ajax({

type: "POST",
url: "../WebService5.asmx/getseonval",
data: JSON.stringify(theValue),
dataType: "json",
contentType: "application/json; charset=utf-8",

success: function (data) {
OnSuccess(data.d);
},
error: function (xhr, status, error) {
OnFailure(error);
}

thanks pradeep. your code worked for me.

Thanks a lot.. i will check

Thanks Mr.Kumarbs it works now..

like this

if @view="xxx" then i need to show heading1 else need to show heading2

i understood by your explaining params is not a optional paramter. i asked what else way to give optional paramter in web method..

I am sorry.. but if you use params keyworkd in noraml application. it did not show any error see below,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication4
{
class Program
{
public int test(int i,params string [] s)
{
return i;
}
}
class t : Program
{
static void Main(string[] args)
{
t obj = new t();
int li = obj.test(4);
Console.WriteLine();
Console.ReadLine();
}
}
}

can you help me how it works? and i want to use optinal parameter in my .net xml webservice method. how to use optional paramter. kindly suggest me

I tried like this too

his.Master.Bind_Master_ProductsGrid();

It calls master's funtion and also has records in Gridview1.DataSource but Gridview1.DataBind() is not binding i guess as still i am getting nothing in gridview

Yes You are correct. But i am calling master's function from inside the button click envnt of child page not page load event handler.

for ex:

product.aspx:

consider update_cart_click button click event.
protected void update_cart_click(object sender , EventArgs e)
{
..//binding gridview cart and inserted into data base which is in child page.

when you click update_cart_click compiler will call page load then will go to master page then will go update_cart_click event.

Now i need to update same thing to master page function from here i need to call master page function. Normally from here will not go master page right?
how to do that?

That is why i added this to access master page function in product.aspx
<%@ MasterType VirtualPath="~/Site.master" %>
then i called inside the click event like below.
Site myMasterPage = Page.Master as Site;
myMasterpage.Bind_Master_ProductsGrid();

ya now that function calls successfully and i have the records Gridview1.DataSource = dt; but Gridview1.DataBind() is not binding so girdview shows empty.
}

okay pls take a look

You are right. I will try myself.

hi Naz, your code worked for me thanks a lot.

byte[] imgData = (byte[])reader["icon"];

File.WriteAllBytes("your apps local folder path", buffer);

but small correction i made in your coding. i used imgData instead of buffer ..

hello Ajith.. ofcourse to add folder . we have to right click in solution explorer. can you read my question clearly.. the question is how to save image once writted from byte.

Hi Syed, as you said. i worked on that. now it binds for child node only. but the issues the image shows only for child node. parent node is showing empty image.

hi. i used for each only.. i posted full coding. you can see what is the problem

private void bindingroodrecord()

{

sql = "EXEC [sp_parent_record]"; //stored procedur to get parent records

SqlCommand cmd = new SqlCommand(sql, objConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt1 = new DataTable();
da.Fill(dt1);
Session["parentnode"] = dt1;

PopulateNodes(dt1, TreeView1.Nodes); ///////// for parent node

}

private void PopulateNodes(DataTable dt, TreeNodeCollection nodes)
{
foreach (DataRow dr in dt.Rows)
{
TreeNode tn = new TreeNode();

tn.Text = dr["columnfield"].ToString().Trim();

tn.Value = dr["code_webcategory_id"].ToString().Trim();
tn.ImageUrl = string.Format("image.aspx?category={0}&width=50", tn.Value);
nodes.Add(tn);


tn.PopulateOnDemand = (Convert.ToInt32(dr["childnodecount"]) > 0);

}


}
The above coding works fine.

NOTE: image.aspx, image comes from database(which comes as byte) and then writting as image using System.Drawing.Image bitmap = System.Drawing.Image.FromStream(stream),......the image comes from database and binds in tn.imageurl correctly.

so, right now as i have 100 records it binds image 100 time which is ok.

now the below coding to bind child notes

protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e)
{


PopulateSubLevel(Convert.ToInt32(e.Node.Value), e.Node); // i am getting parent node when user click (populate)on treeview to form a child node for parent node.


}

private void PopulateSubLevel(int parentid, TreeNode parentNode)
{

SqlCommand cmd = new SqlCommand("sp_getchildrecords", objConn);/// this is the stored procedure to get child node using parent id.
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@parentID", SqlDbType.Int).Value = parentid;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
Session["childnode"] = dt;
Session["childnodess"] = parentNode;
TreeNode childrecords = (TreeNode)Session["childnodess"];

PopulateNodes(dt, childrecords.ChildNodes); // to form child nodes


}
this also works fine. but,

Now, consider the child node has 10 records. once the populateNodes function gets over , it calls image.aspx to get an image. Now it binds 110 time again instead of binding 10 times.

thanks for reply. i made the mistake. I fixed that one. if we do not declare AllowPaging="true", it will not work. so, for gridview,listview , we have to declare paging stuff whenever we are accessing id of gridview and listview in Javscript.

Hi thank you. which option is good?

the first option i understood. i will try.

what is the second option. how to do that? can you give an example?

Okay Thanks a lot for good clarification Mr. RyanDev.

Thank you Mr.RyanDev, but few of them suggested me that you can generate own self-signed certificate if i have own IIS(web hosting provider). i have own web hosting provider.

hi JoCodes, i have used ajax frameworks using update panels only..let me try with your other suggession. Thanks a lot.

okay.

hi Richard, Sampath,

I am sorry for not clear..i mean my javascript function is not invoking when i click on click button"see price in cart"

okay thank you for suggesting me.

Hi phil . Thank you. i got solution by you.

hi Karthik, Thanks a lot. Excellent..your coding works for me. i rated 5 for you. Thank you so much.

Thank you. i understood what you example story imparts. i am not binding two tables from database. i can take row number from database using this query below:

SELECT ROW_NUMBER() OVER (ORDER BY ColumnA DESC) AS RowNo,
ColumnA,
ColumnB,
ColumnC
FROM YourTable
but, when you do first iteration. it comes correctly. the first time result would be like,
rowno name
1 chris
2 Ram
when it finishes second iteration , the result will be below as i am merging into one table:
rowno name
1 chris
2 Ram
1 avanash //see again it starts from 1. it is supposed to start 3.
2 karthick.

few people suggest use key for two table. that is not possible. becuase for example i mentioned two table. like that i am merging morethan 10 table' records in one datatable. that is why i made that Rowno is not coming from database. because i need to build rowno from front end like adding column as rowno.

Thanks a lot Dineshshp!.

can you give example?

can you give example.

hi thatraja,Rohan Leuva and King_fisher,
yes i am taking row number from the database and i did not show anywhere. i am showing records in datalist over the site. for paging concept i need row number. in datalist, there is no option for paging. we have to make paging using row number. That is why i need row number for paging.

okay i will try.

Thank you. i saw you link. that was paging concept. but my requirement is different. kindly read my question again. please give any example.

Hi prabakar, i did not see that link which was my mistake. i can try now. i like your quotes - no pain no gain.

hi prabakar, Can you give example please

Thank you

Yes you are correct. that is what i need.

hi i have brand for tools for example consider bosch is a brand. so, this bosch contains many categories so, bosch is 'B' serial in alphabetical right? like that there are several brand which some start with A or B or C or D .......or Z serial. so, now i want to seperate A-B brand, C-D brand......Y-Z brand so that user choose which they need. how to do in asp.net c#. i think we have to use datalist concept. please guide me in correct way.

I got it. Thanks a lot!.

<asp:GridView Width="100%" runat="server" ID="sh" AllowPaging="true"
ShowFooter="true" Showheader="true" GridLines="None" ondatabound="GridView1_DataBound">

hi we are allocating contact to context which is object. we can only retrun context not contact. if i do above you said, i

hi thank you for reply. i did what you said follows
context.ContactDetails.AddObject(contact);
context.SaveChanges();
return context;

but in return statemetn shows error like : cannnot implicitly converttype'winwebapi.chdbentities to winwebapi.contactdetail'

hi i think the .net 4.5 does not work on XP, while .net 4.0 works on every OS from XP till win8. right?

hi you are correct. so what i need, when you click node it will expand it's child , second time you will click some other node to expand it's child right? that time first time expanded node should collapse automatically.

Am i cleared. pls help me.

hi, simple solution.


if we remove var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;

now works fine...

hi i did with prerender. but it is not working

thank you.
