Hi Nigam,
In the Datagrid try with this Code.
//set the action to handle the contextmenu
function oncontextmenu(event)
{
event.cancelBubble = true;
event.returnValue = false;
this.action("contextmenu");
}
// assign the event handler to the cell template prototype
Active.Templates.Text.prototype.setEvent("oncontextmenu", oncontextmenu);
// create action handler for the right click context menu
grid.setAction("contextmenu", function(src){ showmenu(event,getMenuHeader()+menu);return false;});
I hope this will works.
Happy Coding

Hi,
Why dont you use ItemDataBound event ? You can validate each and every cell in there and that too without help of javascript.
I hope i got your point !

hello thanx for replying me.
when i download the zip of anthem example then its not openning it into the dotnet 2003.
is it done by ajax in this example.
thanx

hi again;
The zip file is the whole anthem project,after you have unzipped the file you got to open it's .net 2003 solution or project file in .net and then compile the project. From there you end up with a .dll file which you should use in your own project.
You have to import the .dll file as reference and in your toolbox as Anthem Tab.
Now you could use the timer control and solve your problem.
Hope the guide would be helpfull

can any one give me the code for the following process
We have to insert Wave files in to sqlserver and then develop a webpage with a search option.
When we enter a word and do a search on that, we should get all the sound files containing that word.
Thanks in advance,
Suri.

Store the words as text along with the sound data, so that you can search that.

Hi,
Here's some code to get you started:
CREATE TABLE MyMp3s<br />
(<br />
Mp3Image image<br />
)<br />
GO<br />
<br />
CREATE PROC InsertMp3Image<br />
@Mp3Image image<br />
AS<br />
INSERT INTO MyMp3s VALUES(@Mp3Image)<br />
GO<br />
<br />
<br />
Int32 m_MaxFileSize = 10240000;<br />
<br />
SqlCommand storedProcedure =<br />
new SqlCommand("InsertMp3Image" , SqlConnection);<br />
storedProcedure.CommandTimeout = 30;<br />
storedProcedure.CommandType = CommandType.StoredProcedure;<br />
<br />
System.IO.BinaryReader binaryReader =<br />
new BinaryReader(<br />
new FileStream (@"C:\Mp3\MyMp3.mp3",<br />
FileMode.Open,<br />
FileAccess.Read));<br />
<br />
byte[] buffer = binaryReader.ReadBytes(m_MaxFileSize);<br />
<br />
binaryReader.Close();<br />
<br />
storedProcedure.Parameters.Add( "@Mp3Image", buffer );<br />
<br />
storedProcedure.ExecuteNonQuery();
I copied it from -

As the other person told just store some unique information relating to the sound files in the database and search the db for this unique key!

After converting my first ASP.NET 1.1 project to 2.0, I discovered that one of my button's onclick handler wasn't working. I then proceeded to inspect the InitializeComponent code to find that it was empty. Also there was no declartion of the button control -- or any other control present. Where does ASP.NET v2.0 put this code? Also, is there any way of fixing my problem in code or do I have to delete the button and re-create it so that ASP.NET v2.0 can do it's "under the hood" stuff right?

The reason this works has to do with the partial keyword applied to your codebehind class. In addition to turning your .aspx file into a class definition with methods for rendering the page, as it has always done, ASP.NET now also generates a sibling partial class for your codebehind class that contains protected control member variable declarations. Your class is then compiled together with this generated class definition and used as the base class for the class generated for the .aspx file. The end result is that you essentially write codebehind classes the way you always have, but you no longer have to declare (or let the designer declare for you) member variable declarations of server-side controls.

My basic problem is that one of my buttons, that used to work in the 1.1 version no longer works after the application was converted to 2.0. By that I mean that that the OnClick event doesn't fire. In 1.1 the probable culprit would be a missing "wireup" in InitializeComponent. Now the only reference to the button control that I control appears to be the one in the "html" in the aspx page. Would it help to delete this reference and re-create it? According to what you say it wouldn't appear to matter whether I used an editor or the designer to do this.

Are you using the CodeFile keyword in your @Page directive?
What about runat="server" in the button? (Just making sure)

How do I go about letting my client adjust which columns they do and do not want to see in a gridview? I would like to have a separate page that holds all of the columns in the database and they can check or uncheck the ones they want.

One way I've done this is by using code to construct the SQL SELECT statement (using only checked columns), then binding that to a gridView with AutoGenerateColumns set to true.

I actually did it with a btn and a checkBoxList with the event as follows:
Protected Sub btnUpdate_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim li As ListItem
For Each li In CheckBoxList2.Items
Select Case li.Value
Case 0
If li.Selected Then
GridView1.Columns(0).Visible = False
Else : GridView1.Columns(0).Visible = True
End If
Case 1
If li.Selected Then
GridView1.Columns(1).Visible = False
Else : GridView1.Columns(1).Visible = True
End If
Case 2
If li.Selected Then
GridView1.Columns(2).Visible = False
Else : GridView1.Columns(2).Visible = True
End If
End Select
Next
End Sub
I am going to update this soon to use a loop to cycle through list items of and columns of unknown amount

I am working on a project where I would like to be able to search a gridview dataset and return only the results back to the same gridview. I am relatively new to this so your help would be greatly appreciated. This site has already been so much help.

It's the same as loading all the data into it. All you have to do is create a search form on the page with a button. In the button click event, pass the info the user enters in the search form into a function in your data layer which contains a select query/ stored procedure that returns only the results that match. Then bind the returned dataset to your gridview. Something like this:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then BindIt()
End Sub
Sub BindIt()
Dim ds As New DataSet
ds = data.GetEverything
If ds.Tables.Count > 0 AndAlso ds.Tables(0).Rows.Count > 0 Then
gdv.DataSource = ds
gdv.DataBind()
End If
End Sub
Protected Sub btnSearchSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearchSubmit.Click
Dim ds As New DataSet
ds = data.GetData(parmaterfromsearchform, another, another)
If ds.Tables.Count > 0 AndAlso ds.Tables(0).Rows.Count > 0 Then
gdv.DataSource = Nothing
gdv.DataSource = ds
gdv.DataBind()
Else
gdv.DataSource = Nothing
gdv.DataBind()
End If
End Sub
