Hi,
For the GridViews RowDeleting event, access the ID and remove it.
Here is the steps to follow. After successful deletion re-bind the list to the GridView control.
1. For the delete button, set CommandArgument as the ID.
<asp:Button ID="btnDelete" runat="server" CommandName="delete" CommandArgument='<%#Eval("product_id")%'> />
2. For the RowDeleting event.
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete");
if (btnDelete != null)
{
int iProductID = Int32.Parse(btnDelete.CommandArgument);
if (Session["lstProduct"] != null)
{
List<Products> lstProducts = (List<Products> )Session["lstProduct"];
Products oProducts = lstProducts.Find(delegate(Products p) { return p.product_id == iProductID; });
if (oProducts != null)
{
//Give a message : record deleted successfully.
lstProducts.Remove(oProducts);
Session["lstProduct"] = lstProducts;
GridView1.DataSource = lstProducts;
GridView1.DataBind();
}
}
}
}
Hope it helps,
Thx,
Gayani

Products oProducts = lstProducts.Find(delegate(Products p)
what is delegate?I did't use product class.here is my code:
if (Session["basket"] == null)
{
List<string> pid = new List<string>();
pid.Add(productid.Trim());
Session["basket"] = pid;
}
else
{
((List<string>)Session["basket"]).Add(productid.Trim());
}
</string></string></string>
Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete");
I don't have RowIndex in my smart list.

Hi Gurus,
I have a tab container and under a tab panel I have datagrid .
When I dynamically populate the datagrid I find its height is more than the height of the tab panel / container. I do not get scrollbars for the tab panel. It gives me effect that my datagrid is overlapping my tab container.
How should I make datagrid remain inside the tab panel but still let it grow and in turn have scrollbars.
My code is
<ajaxToolkit:TabPanel ID="TabPanelResult" runat="server" HeaderText="TabPanel1" >
<HeaderTemplate>Result</HeaderTemplate>
<ContentTemplate>
<div align=center
<asp:datagrid id=dg_SearchResults runat="server" Width="262px" Font-Names="Verdana" Font-Size="7pt" PageSize="5" HorizontalAlign="Left" AutoGenerateColumns="False" AllowSorting="True" AllowCustomPaging="True" ForeColor="Black" CellPadding="2" BackColor="White" BorderWidth="1px" BorderStyle="Solid" BorderColor="#999999">
<FooterStyle Wrap="False" BackColor="#CCCCCC">
..
..
..
..
</TABLE>
<%--</asp:Panel>--%>
</div>
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
Please give me some feedback.
regards
vijay

Dear .netman,
first of all you can not use aggregate functions (like sum, avg) without using Group by clause.
and another thing also you can not use aggregate functions in where clause. you have to use Having clause with group by clause.
select * from table where field1 not in (select field2 from table2 where field3 like '%05/09/2008%' gruop by field2 having sum (field3) < 1)

Use an asp.net button. After you run your code on the server use registerClientScriptBlock or whatever it to send the javascript to the client to close the window.
If you want to run a server side function from javasript you can use ajax to do that. The best method for that would depend on what version of asp.net you are working with.
I didn't get any requirements for the signature

pls help restricting multiple logon to an application with single user account.
Here wht m doing is ,
m checking login details against a database.
if is a valid user then allowing to browse throuth the application.
my requirement is if one user is loged in and if someother user tries to login with same user account i need to restrict the second user saying "this login is already in use".
I can maintain a temp table for this , whenever a login is success i can update "isloged" field as true and we can set it false when user logs out. but how can we handle situations like
if a user logs in and closes bowser close button instead of log out.
if a user logs in and leaves doing nothing.
pls help in resolving this, if possible write a sample code for me.
thanks in advance.

Create a template column in the gridview. Add a label to that column lblSessionDate.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblSessionDate = (Label)e.Row.FidnControl("lblSessionDate");
lblSessionDate = currentDate.toString(SessionItemClass.DateFormat)
//It is always a good idea to create a class to access session items.
}
}
in your aspx markup add the property to the gridview OnRowDataBound="GridView1_RowDataBound"
I didn't get any requirements for the signature

try this
<%# Bind("date",session("date_format"))%>
if you are using c#, chage session("date_format") to session["date_format"]
Let me know if it works
