I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?

let said my gridview have 3 records with checkbox features. If i want to delete the checked record, i will retrieve
the these records and store into a temporary datatable.After that , it will deleted the record if checked is true.However, it;s only
work when u delete one by one or whole record as once. This is because if u deleted the second record at position 1, then the third record
at position 2 will moved up.

I have a GridView. One of its columns contains monetary amounts. Underneath the GridView, I have a SqlDataSource which calculates the sum of this column and displays it in a label which is in a DIV called totalsbox (that I have added runat="server" to).
Obviously, if the GridView is empty, I don't want this label to be visible.
In the Page_Load, I have placed the following code:
[Code]....
[Code]....
This works fine. When the Page first loads, if the GridView is empty, the entire DIV is hidden; if not, the DIV is visible and the label displays the column SUM. imagine now the GridView DOES have rows, the DIV is visible and the total is displayed properly in the DIV ("£10.00", say).
I have a RowDeleted event handler in the code behind which contains exactly the same code as I put in the Page_Load. As I delete rows, one by one, the sum is recalculated and displayed properly. But, when I delete the final row, I would expect this code to hide the DIV as the GridView is now empty.
This doesn't happen, however, the DIV remains visible and I have, in the label, something like "£ ".
Why is it that the code works in the Page_Load but not in the RowDeleted event handler?
I have a Drop Down List, a GridView and a DetailsView. The Gridview is the master, the details is the records detail view. When we edit a record and click the update button, I want the page to refresh the gridview and detailsview. Right now after clicking the update, nothing happens, it just updates the current details record.
View 3 RepliesI have wired an event to handle delete command for my GridView. But I cannot determine which the record's unique key, in my case stored in DOCIDNO field. All I get is a row index, such as 0, 1, 2 which obviously cannot be used to accurately delete a record from database.

I am trying to delete a row in the GridView with an ImageButton Link. By clicking the button, the GridView row is set with a backColor = "Red" and with delete confirmation window.

<asp:TemplateField HeaderText="Delete?">
<ItemTemplate>
<asp:ImageButton ID="deleteImageLink" runat="Server" ImageUrl="~/images/Delete.gif" CommandName="Delete">

deleteButton.OnClientClick = "if (confirm('Are you sure you want to delete this user account?') == false) return false;";

I have a gridview in a web page that shows some data from a table; in the same page I have a button that onClick executes a SQL Server job (the job has 9 steps and it takes around 20 seconds to execute).
How do I modify my code so that the page is smart enough to wait until the job is executed and refresh the gridview with the new data? Currently this is what I have:

The last method (GridView1_RowDataBound ...) is for having the background to red if some condition occurs.

Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...

I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?

I have a Gridview connected to an Access database using a Datasource and a query SELECT * FROM [Staff]. In order to update the grid view I have to do it in the IDE and click Refresh Schema. I have tried:
StaffList.SelectCommand = "SELECT * FROM [Staff]"
StaffList.UpdateCommand = "SELECT * FROM [Staff]"
StaffList.DataBind()
Staff.DataBind()
At runtime I want it to update the Gridview.
StaffList.SelectCommand = "SELECT * FROM [Staff]"
I have a gridview that has allowPaging and AllowSorting set to true. It is bound to a sqldatasource with the selectCommand firing a sql query. The sqldatasource has EnableCaching = true, and caching duration = "60". The idea is to run the paging, sorting, etc from the cache.
A separate dataUpdate event updates the data that is being loaded in the grid view, but I am not able to see the change in the gridview data till 30 seconds (caching duration) .
What is the best way to force refresh the gridview data by the dataUpdate event?
I came across this artice that tells to use CacheKeyDependency, but when I implemented it, the gridview gets refreshed at every dataUpdate event, but also the paging and sorting fires the sqldatasource Selectcommand sql query. I want this query to be fired only on dataUpdate.
Is there a good way to add a new gridview row so that it appears at the top of the gridview in edit mode? I've researched a lot of methods but they're mostly adding blank data rows. I'd like to add the new gridview row and then use an insert to add the new record to my linq datasource.
