View 5 Repliesin my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

View 1 RepliesThis is my aspx pages button properties:
<asp:Button runat="server" ID="cmdConfirm" Text="Select
Customer"
ValidationGroup="ValidateId" Height="26px" onclick="cmdSave_Click"/
Now on my Page_Load I have:
protected void Page_Load(object sender, System.EventArgs
e)
{
Name = Request.QueryString[0];
LoadCustomer();
cmdConfirm.Attributes.Add("onClick", "update("
+ Name + ");");
Conn.Close();
}
This is my button click for Select Customer button.
protected void cmdSave_Click(object sender, EventArgs
e)
{
RecordChanges();
}
Now I must run cmdSave_Click() before the cmdConfirm.Attributes.Add even though both is for same button anyway. I know that client side script will try to run first but I must run the cmdSave_Click event first to save the data. Aftre that cmdConfirm.Attributes will send the Name to the next page using a Javascript function where the stored values(stored using cmdSave_Click) will be used. I have no other choice. I cannot run the Javascript function first as it will happen before the data is stored. And also I cannot use another page as all has to be performed in one page so that user will not have to click Save twice. Can anyone tell me How I can delay the cmdConfirm.Attributes.Add until the cmdSave_Click is performed.

how to perform Edit/Update & cancel in the grid view .. already the data is there in the gridview
[code]....
I have a webform which uses a gridview control to show result of a search operation.I wanna to take advantage of using pagination in the webform. But as you all know, gridview pagination is a client-side pagination and it transfers all records have been selected to the client. What I mean by client-side pagination is the client (page) shows records page by page but every time the user clicks on a page link to navigate through records, all the records are selected from Data Source.How can I use gridView with datapager in order to have a server side pagination? Or any other solution to get records page by page by configuring our query?

I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?
I've got a function I wrote quite some time ago that works fine, but I'd like to speed up the process and lessen server load by doing the same job in Javascript.I seem to be able to GET textbox values ok, but I can't seem to SET textbox values (I'm'-a JS noob).

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
