Web Forms :: Deleting A Control From A Dynamic Table?
Apr 1, 2010
the problem i that I'm filling a static table with dynamic rows, cells and controls. Add control to cell, add cell to row, loop, add cell to row, loop, add cell to row, loop, add row to table, loop etc etc. After a user makes a selection, the table should clear and repopulate with new data. The thing is, when the next set of data loads it seems the first text box in the first cell retains old data... I've checked the procedure and stepped through where the box is loaded into the cell... all appears fine. 'm doing a table.rows.clear() before re-population and I'm guessing I'm not dropping the controls?

This script is throwing errorMicrosoft JScript runtime error: Object doesn't support this property or method How can i solve this? Is there any other way to remove the row when "delete" is clicked.
I am trying to generate a dynamic table andd add rows to a ASP.Net table control on my UI. My problem is as I add a new row from MyTable, in to another table the table I am copying from, will loose one row. Here is the code:
Table myTable = new Table ();
[Code]....
am just reading one row in every loop and add that row in to another table object, why is 'myTable' loosing loosing one row in each loop?

I´m looking for some advice on how to create an table showing bookings, a table containing mon-sun on the horizontal axis and times at the vertical. The admin is able to edit each days bookable times (first bookable time, last bookable time) - The slottime is constant.
What I want is let the admin click on eacha cell to remove it/add it when removed. And other features as well, like create an booking for a customer.
What would be the easiest way to achive this, at the moment I use dynamic links since I cant get asp:buttons to work and the code to create an dynamic asp:table row by row and this produces some ugly code.
So any advice on how to achive such an "schedule".
I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1 2 Record2 3 Record3 4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1 3 Record3 4 Record4
...if I then hit refresh...
1 Record1 4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server"> <asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" /> </asp:LinkButton> protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) { if (e.CommandName == "Delete") { int ID = e.CommandArgument.ToString().Numeric(); db.SPs.SpDeleteAccount(ID).Execute(); UI.Confirm(uiBroadcast, "Account has been deleted", "300px"); BindAccounts(); } }
I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet.
I'm trying to create a list (customized table) with data pulled from the database and display it to the user in a format that looks very much like a forum thread and replies or posts.Which each of these "posts" I require to have buttons specific to that particular column to edit, delete etc.How do I create buttons on the fly and associate an event handler (button clicked) method with it?
I want to remove parent control (which is span in this case) without deleting its children controls from container. how can I accomplish this in asp.net c#?
you can see the code here: http://pastebin.com/9NiriWXN
Note: I can easily find the "newsright" control and return its parent (which is span in this case)
