use css style for table Cell.
this can be added from server side while rendering the grid cell.
style.textOverflow = 'ellipsis'
Or you can iterate the grid cells as TD , set the below attribute to the TD.
TDCell.style.textOverflow = 'ellipsis'

Means you want to use AJAX but not updatepanels.
If it is right then you've the option of using XMLHTTPRequest and XMLHTTPReponse object using XML.By this send the data to server and get the response.
Cheers!!

To run an .exe file on client side without informing the user / os is similar to any virus activity.
Normally the client browsers + OS sense the .exe files trying to execute and blocks it asking user either to go ahead or not.
Programmers who have tried infecting client computers may help you but this is not good.

Hi,
This is my first question posted here so please go easy on me 
I've been searching around and trying all sorts of things to solve this problem but still no luck...
after I bind the data to the wanted GridView, I can not address a specific column that I want to set to visible = false.
I keep getting this error: "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index". Debugging shows that Grid has data and it is not empty, so I do not see a reason for this to happen.
here is an example code and the stack trace:
private void GetUpdated()
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
dt = myData.RetrieveData("db_GetCaseLastUpdate").Tables[0];
dt.Columns.Remove("IncidentId");
dt.Columns[1].ColumnName = "Last Modified";
grid_Update.DataSource = dt;
grid_Update.DataBind();
grid_Update.Columns[0].Visible = false; <-- sorce error
}
Stack Trace:
[ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index]
System.Collections.ArrayList.get_Item(Int32 index) +2880797

System.Web.UI.Control.LoadRecursive() +47
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1436
Also, I can't seem to find a way to change a column's width.
I hope this is the right forum for this question...
TIA for your help!!!

follow the below:
1.
for (int index = 0; index < this.grid_Update.Columns.Count; index++)
{
if (this.grid_Update.Columns[index].HeaderText == "SomeHeader")
this.grid_Update.Columns[index].Visible = false;
}
2. "SomeHeader" is nothing but the column header.

Is there any page unload event in asp. I need to remove some session information when i closing the page. Please help me how to do this.

Dushan:
No events are fired when browser is closed. Handle the JS event when browser closes and send AJAX call to server which should call a method and clears the necessary sessions.

I am new to asp. I want to ask very simple question. If i declare page level non static private variable the data in that variable is unique to that session(user).

if you create a page level variable then it won't be accessible from other pages.It will for that user for that page only
Cheers!!

It's unique for that instance of the page class, i.e. you get a new variable every time there is a request for the page. You can't use the variable to keep data from one page request to another.
Despite everything, the person most likely to be fooling you next is yourself.

VB CODE:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim tr As New TableRow
Dim tc As New TableCell
tc.Controls.Add(New TextBox())
tr.Cells.Add(tc)
Table1.Rows.Add(tr)
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tr As New TableRow
Dim tc As New TableCell
tc.Controls.Add(New TextBox())
tr.Cells.Add(tc)
Table1.Rows.Add(tr)
ListBox1.Items.Add("makarena")
End Sub
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Label1.Text = Table1.Rows.Count
Label2.Text = ListBox1.Items.Count
End Sub
HTML CODE:
<body>
<form id="form1" runat="server">
<div>
<asp:Table ID="Table1" runat="server">
</asp:Table><br>
<asp:ListBox ID="ListBox1" runat="server"></asp:ListBox><br>
<asp:Button ID="Button1" runat="server" Text="Button1" /><br>
<asp:Button ID="Button2" runat="server" Text="Button2" /><br>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br>
<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></div>
</form>
</body>
I made a test page-code - please help to understand why it is working the way it is working....if I click on button1 table1 will get 1 extra textbox, no matter how many times I click after that it will be still 2 textboxes and once I click button2 table1 one will appear with only one textbox again, but with listbox items everything working as I wanted (button1 add items and button2 count them)

ASP.NET won't maintain viewstate for dynamically created controls. Dynamic controls has to be created on each request. Best place to create dynamic controls is OnInit method.
Alternatively, you can put the textbox in a template column in a gridview/datagrid. When the button is clicked, add a new row to the gridview's datasource and rebind the grid. So the newly added row will have the texbox and it's details will be kept in viewstate by ASP.NET along with the parent control (gridview).

Please elaborate a bit more clearly. Do you mean session variables and that type of thing?

Using session is trivial.
Session["Key"] = YourObject;
YourObject = (YourObject)Session["Key"]; Session will have a unique id called SessionId which will be sent along with the request to determine where to look for session data.
bsse wrote: i have to transfer a huge data from one page to another in my site
Keeping huge data in sessions should be avoided. Session variables are kept on server and your server will die when huge data is set on session. You can update the data to a database table and access it from the other page instead.

hi all,
i am not able to update the database using gridview.
the code which i written is mentioned below
protected void Row_Updating(object sender, GridViewUpdateEventArgs e)
{
// Label lblId = (Label)CustomerGrid.Rows[e.RowIndex].FindControl("lblContactName");
TextBox txtName = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtContactName");
TextBox CompanyName = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtCompanyName");
TextBox Designation = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtDesignation");
//CustomerGrid.EditIndex = -1;
string myQuery = "UPDATE [customer] SET [Contactname]=@Contactname ,[CompanyName]= @companyName,[Designation] = @Desgination where [CompanyName]= @companyName";
string dataBaseConnection = "Data Source=DAYAKAR\\sqlexpress; Initial Catalog=hospital;Integrated Security=true";
SqlConnection updateCon = new SqlConnection(dataBaseConnection);
SqlCommand updateCommand = new SqlCommand(myQuery, updateCon);
//updateCommand.Parameters.Add(new SqlParameter("@Contactname", SqlDbType.VarChar, 50));
//updateCommand.Parameters["@Contactname"].Value = txtName.Text;
updateCommand.Parameters.AddWithValue("Contactname", txtName.Text);
updateCommand.Parameters.AddWithValue("CompanyName", CompanyName.Text);
updateCommand.Parameters.AddWithValue("Designation", Designation.Text);
SqlDataAdapter updateDA = new SqlDataAdapter(updateCommand);

string sqlStatement = "Select * from customer";
SqlConnection con = new SqlConnection(dataBaseConnection);
SqlCommand myCommand = new SqlCommand(sqlStatement, con);
SqlDataAdapter da = new SqlDataAdapter(myCommand);
DataSet ds = new DataSet();
