The easiest way to do this is to bind the grid (initially) to a dataTable.

When you want to add a new row Create a clone (or empty) version of the initial table.

On the event where you want the new row, iterate through the grid adding a new row to your empty table for each row in the grid assigning the values based on the cells in the grid.

Then add a new row to the datatable that has blank or default values.

Rebind the grid to your new datatable.

I didn't get any requirements for the signature

Scenario,

I have an Asp.Net page which has 3 panels, with 3 different pages, Left, Middle and Right. I have a user control in Right panel, and am raising an event in that. I want to Handle that event in my Middle panel without including the user control without including the user control in the Middle panel. Is there a way I can do it ?

Hope it is clear !

Thanks in advance !

Place this code on Page_Load()

form1.Attributes.Add("onkeydown", "var btnLeft=document.getElementById('" + <big>btnLeft.ClientID </big>+ "');var btnRight=document.getElementById('" + <big>btnRight.ClientID</big> + "');if(btnLeft && event.keyCode==37){btnLeft.click()};if(btnRight && event.keyCode==39){btnRight.click()};}")

btnLeft and btnRight are the IDs of your left/right buttons.

Bad Idea. Why you cant give visible property to false or Style="display:none;"?

Ajita Kumar Satpathy wrote:

You can call server side function in JS.

fiend,
this is not my question. Please understand the question carefully.

My page inherit master page.I've a update panel. Inside update panel there is an image control, a label, a button (say Button1). There is an anchor tag outside the update panel. My motto is to show image (in image control) & data (in label) on clicking the link(anchor tag). For this I've called the onclick() event of the Button1 in anchor tag ike this :--
document.getElementById('ctl00_ContentPlaceHolder1_Button1').click();
And code is written in Button1_Click event.Actually there is no necessity of Button1 to show to user. So I've made its height & width to zero. (Your suggestion is right i.e. make visible false of the Button1).

When I click the the anchor tag, in IE, both data & image is displayed. But in Firefox Mozilla, only data is displayed. Image is not displayed. This is actual problem.

Thanks in advance

sqldatareader and inner join problem, not getting all records, PLEASE HELP

i have this code, when i run this page, this reader dont bring the first record. i ran this sql(SELECT) on the sql database and runs fine, and if i put the seme SELECT in a Sqldatasource and bind the griview, it works fine too. what is wrong with this reader?
******************
any idea.
THIS WORKS

SqlDataSource1.SelectCommand = "SELECT products.pid, products.pname, flavors.fl_name, product_flavors.flavor_icon FROM product_flavors LEFT JOIN flavors ON product_flavors.flavorsid = flavors.flavorsid LEFT JOIN products ON product_flavors.pid=products.pid WHERE products.pid = 84"
ProductListView.DataSource = SqlDataSource1
ProductListView.DataBind()

**********************
THIS NOT BRING ALL THE RECORDS. ALWAYS LEAVE ONE OUT.I THINK THE FIRST ONE.

Dim conn As SqlConnection
        Dim cmd As SqlCommand
        Dim cmdString As String = "SELECT products.pid, products.pname, flavors.fl_name, product_flavors.flavor_icon FROM product_flavors LEFT JOIN flavors ON product_flavors.flavorsid = flavors.flavorsid LEFT JOIN products ON product_flavors.pid=products.pid WHERE products.pid = 84" 
        conn = New SqlConnection(ConfigurationManager.ConnectionStrings("eConnectionString").ToString)
        cmd = New SqlCommand(cmdString, conn)
        conn.Open()
        Dim myReader As SqlDataReader
        myReader = cmd.ExecuteReader()
        myReader.Read()
GridView1.DataSource = myReader
        GridView1.DataBind()
        conn.Close()

I think the above line is the problem
When you Use Read reader move to next record.

Instead of binding the reader try to bind DataTable.

cmd = New SqlCommand(cmdString, conn)

myReader = cmd.ExecuteReader()

Dim adp as new SqlDataAdpter(cmdString,conn);<br />
Dim dt as new DataTable<br />
adp.Fill(dt);<br />
GridView1.DataSource = dt<br />

Try removing the line
myReader.Read()
before binding it to the GridView

The DatReader is a forward-only cursor and you have moved it one record on by reading from it.

You might want to check that ANY rows are returned first though - use
If myReader.HasRows Then....

When you want to disable?Or In which event?

You need to pass the button id MyButton.ClientID to the JS Function.
