I have the reorderlist and a DELETE as link button. So far so good as far as I can tell that when I clicked on the delete link button, it deletes photo value from the database per the ID PK. However, I want to be able to delete the right photo file on the server/disk (jpg, gif..) but I could not figure out the logic to do so.

Is there a better way to write this sql statement? or convert the UserId to int32 before executing? Not sure how to do that.
I have tried several examples of reorder list with several types of data sources and can't get the list to reorder. I have copied Joe Stagner's code from his Video on Reorder Control with the same result. Here is the Video
http://www.asp.net/ajax/videos/how-do-i-the-ajax-toolkit-reorder-control. Page loads, but I can't drag items to reorder. I have tried this with explorer 8 and firefox 3.6, with and without security. Here is the markup, no code behind.
[Code]....
Some of the events don't seem to fire. DataBinding, DataBound, Load, and InsertCommand work ItemReorder does not, (not good for a reorder control). This control should work, but doesn't. I am able to insert data so it seems that the reorder or dragItem templates maybe causing problems. I have commented out but that doesn't help. Here is my only clue, I had to use the script manager from the .net4 Ajax Control Kit for my events to not complain about definitions. I was only using these events with debugger just to see if they are being called, no code in methods. But I am using the toolkit.dll that came with Joe's example. I tried it with .net4 only first, but that didn't work either that's when I installed the dll from Joe's example.
I'm working on a GridView that has around 75 columns. I'm looking for a way the end user can set the order of columns in which he would like to view so that each time he logs in the order is retained.

I need to create a display grid of picture cells 5 columns by rows determined by database select. Each cell to contain picture, title, name, phone number pulled from database. How do I create a table like structure and populate it? Can a DetailsView control be called into each table cell with the table row count being determined by the same select statement?
View 2 RepliesHow do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

how to retrieve this file information in ASP.NET? I am building an upload page and want to retrieve more information than just the basic file-name, file extension etc info. I am coding in VB. It is written into the file itself so it must be possible to access this information somehow. However, my search efforts so far have not got me very far...
I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
