Page Refresh And Bind Not Working?

Jan 3, 2010

I've got a .aspx and in it an .ascx. In the .ascx I have a server control.

The .aspx has a list of items in a cart The .ascx has a list of some cross-sell items (fed from a custom server control) that the customer can add to the cart if desired both the list of items in cart and list of cross sell items are driven by a repeater and bound on page load. So the .aspx calls a method that rebinds the cart items on page load. And the .ascx calls a method in its page load that rebinds the cross sell items in that custom control (.cs) that is in my .ascx.

The problem I have is, when the user clicks a "add to cart" button in the repeater inside my custom control, the page refreshes and what should happen is the cart items in the .aspx AND the list of cross sells should refrsh showing that the cross sell item was moved to the cart. But even though when I debug and I see the list being rebound with the corret # of items after the move, the page still shows the old state. I have to refresh the page manually again to get it to work.

I guess I need to check for Page.IsPostback? but even if I don't check that..at the least both lists should be refreshing regardless cause I have it in my page load. So even if it's a postback, and I'm not checking for that the lists should show the new state because I'm not even checking for postback anyway. So checking for postaback I don't think is the issue here cause i want the lists to rebind and re-update on any page load....initial or if it's a postback...it doesn't matter. Reload every time. But it doesn't seem to be doing this even though I clearly see the revbind of the lists having the right count (one less on the cross sell and one additional to the cart as it was added after the user clicked the button).

Here's the sequence of events:

User is on their cart page User sees a list of cart items that they have added to their cart already (this list is bound in the Cart.aspx and rebound on every page load)User sees a list of possible cross sell items they can add to their cart somewhere on the page. This list is a custom control found in my .ascx and that .ascx is obviously in my .aspx.

The custom control is just a repeater that lists out the cross sell itemsUser clicks one of the "Add to cart" buttons on one of the cross sells Page refreshes. In the page load of the .aspx AND the .ascx, I am going out to the DB and rebinding both those lists based on the new state...that is, the new lists after the item was added to the cart which means that now the cart items should have one more added to the list and it does...I clearly see that the new list has one more.

The page comes back after the refresh but I don't see the lists reflecting the new state...I don't see the new item in the cart items list and the added cross sell removed from the cross sell list even though again both lists when I debug are showing correct set of records reflecting the new state.

Web Forms :: Declarative #Bind Doesn't Bind In Update Command

I'm curious to know why the database won't update on the click of the Update button:

According to all I've read, the above code should be sufficient. Since CommandName is set to Update, it would seem that no code-behind is necessary.

Forms Data Controls :: Bind A Multidimensional Arry (or List) To A Data Conntrol?

Dec 8, 2010

I would like to bind a multi domensional arry to a data control (at the moment any data control will do - I just want to present the data).

suppose I have the following array:

string[,] strArr = new string[5,3];

strArr[0,0] = "0,0";
strArr[0, 1] = "0,1";
strArr[0, 2] = "0,2";
strArr[1, 0] = "1,0";
strArr[1, 1] = "1,1";
strArr[1, 2] = "1,2";
strArr[2, 0] = "2,0";
strArr[2, 1] = "2,1";
strArr[2, 2] = "2,2";
strArr[3, 0] = "3,0";
strArr[3, 1] = "3,1";
strArr[3, 2] = "3,2";
strArr[4, 0] = "4,0";
strArr[4, 1] = "4,1";
strArr[4, 2] = "4,2";

Forms Data Controls :: Sqldatasoruce Data Type Convesion Error During BInd?

Jul 23, 2010

I have a mySQL datasource pulling back data from a query and populating a formview in edit item mode ( I only use this mode ). All is good. Business logic is such that some dates can be null. When I was putting the null or "" dates into a text box there was no problem, some users had problems with dates so I used the datepicker lite control, now the null or "" dates cause a data type conversion error stating that an empty sitrng "" cannot be cast to type date. It basically barfs here

<%# Bind("OrderDate", "{0:dddd d MMMM}") %>

This is obviously in the asp source portion of the code and there is no code in the classic VB section fo the page, it is all done by drag and drop controls and databinding.How can I fix this error and yet still allow users to put in a date, when applicable, and save the update with the new date added. eg I dont want to take out the databind if I can no longer save that field back to the db.
