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: document.getElementById('ctl00_ContentPlaceHolder1_Button1').click();
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
Thanks & Best Regards

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()

orsini wrote: myReader.Read()
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.
orsini wrote: cmd = New SqlCommand(cmdString, conn)
conn.Open()
Dim myReader As SqlDataReader
myReader = cmd.ExecuteReader()
myReader.Read()
GridView1.DataSource = myReader
<br />
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.

I'm not sure what you are trying to do.
You have repeater and that contains a button atleast. say button1
You have an another button thats outside the repeater. say button2
So on button2 click you want to disable the button1.
If this is the requirement....
1.You can use the FindControl function of repeater to get controls inside therepeater, and pass the ID of button1 to the JS function.
2.You can store the ID inside a hidden field and get it in the JS.
Hop this Helps you...

Hi
I have the following code which should count the number of rows in the gridview ands then I want it to assign a number to it, so if there three rows it would assing 1, 2, 3 to each row but its not working it shows error Cannot implicitly convert type 'int' to 'string'
any help would be great!
for (int x = 0; x < GridView1.Rows.Count; x++)
{
GridViewRow row = GridView1.Rows[x];
dropdown = ((DropDownList)row.FindControl("ddorder"));
int count =+ 1;
dropdown.DataValueField = count;
}

Your Code
for (int x = 0; x < GridView1.Rows.Count; x++)
{
GridViewRow row = GridView1.Rows[x];
dropdown = ((DropDownList)row.FindControl("ddorder"));
int count =+ 1;
dropdown.DataValueField = count;
}
Tip:
Or the control does not exist
or it should be count.ToString();
Int32 count = 0;
DropDownList dropdown = new DropDownList();
foreach (GridViewRow row in GridView1.Rows)
{
try
{
dropdown = ((DropDownList)row.FindControl("ddorder"));
count++;
dropdown.DataValueField = count.ToString();
}
catch (Exception err)
{
}
}
Good Luck
