After Selecting An Item To Edit In A Listview, What Happens Between Each Cycle Of OnItemDataBase

Mar 14, 2011

For some reason, I get an error half way through cycling through my items in a listview right before a record that has a null value for one of its items. It doesnt' haappen any other time. It happens after completing one cycle of the onItemDatabound eventfor a record in a row that is immediately before a particular null value in record immediatley following.My code is written to look for the proper edititemindex, and if it sees it, then it checks for null values for all the items. I can't even get that far, it errors just before the onItemDatabound even runs for the correc edit index

Forms Data Controls :: Validating Page With Listview Edit Item And Insert Item Templates Are Both Present

Aug 9, 2010

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.

The InsertItem Template is in the first position, making it easy to insert a new record.

And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.

I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:

Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If

which works fine also.

The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:

Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub

This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.

Here is the code for a typical entry of the InsertItem Template:

[code]....

All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"

How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

Forms Data Controls :: Multi Selecting Items In A Listview?

Jul 18, 2010

i have the following problem. i'd like to use a listview with paging for mulitple selection of items in a list. The selection is no problem. I do have f.i. a list which holds the key values.

List<Int64> selectedList =
new
List<Int64>();

Forms Data Controls :: Datagrid Item.ItemIndex Keep Selecting The Wrong Row Number?

Sep 1, 2010

I apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work.The error:

Dim ddl As DropDownList = CType(sender, DropDownList)
Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)
Dim rowID As Integer = dgi.ItemIndex

The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)

Forms Data Controls :: ListView Does Not Insert Item?

Mar 13, 2010

What I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.

Forms Data Controls :: Scrolling One Item At A Time With The ListView?

Apr 30, 2010

Suppose I have a horizontally oriented ListView that always shows 4 items and also has a left & a right button: < A B C D >

Now, let's say I have a DataTable containing 20 entries, with indices ranging from 0 to 19.

When the page first loads, this is what'll be displayed: < 0 1 2 3 >

Assuming those buttons are regularly configured DataPage buttons then if I press the right one we'll get this: < 4 5 6 7 >

And if I press the right one again we'll get this: < 8 9 10 11 >

But suppose I'd like the left & right buttons to only scroll one at a time, so that pressing the right one at the start results in this: < 1 2 3 4 >

In such a case, is there a way to configure the DataPager to do this or should I instead introduce regular buttons and perhaps have them call a hidden DataPager?

Forms Data Controls :: Nested Listview As Selected Item?

Mar 16, 2011

have a nested listviews:

Listview1-Item1

<if Listview1.selected index = 0>
Item1NestedListView - item1
Item1NestedListView - item2

When a user selects an item in the parent listview, the nested listiview displays as part of the selected item template - when a user selects an item in a nested listview it correctly populates a third, separate listview. To make sure I'm being clear, I have a parent listview with many rows and each of those rows has a nested listview, that is only populated and displayed when the row is selected. The parameters for the nested listview are set in the ItemDatabound event of the parent.

I had this working fine when both objectdatasources were on the aspx page. However, requirements have changed and we would like to pass a class to the BLL. I cannot figure out how to do this using a datasource on the aspx page. I can pass a class doing a databind in the code behind. However, if I do the databind in the code behind, the SelectedItem template does not get displayed as I would like. I need to find the the selectedIndex for the parent listview in SelectedIndexChanging. however, when I click or 'select' an item in the parent listview, the page refreshes, the ItemDatabound of the parent of the parent fires NOT knowing the selectedindex, then the SelectedIndexChanging event fires changing the SelectedIndex. By this time the Listview is already on the screen without the selectedItemTemplate containing the nested listview. If I click on another item, the when the page refreshes it knows the selectedItemIndex chosen before and displays that SelectedItemTemplate containing the selected index.

Forms Data Controls :: Nested Listview Has Incorrect Item Count?

Mar 8, 2011

I am trying to export a Nested Listview to Excel, but I am having issues with the code recognizing the records in the ListView. When I do a FindControl, that code works fine.The Issue arises when I try to loop through the Items of the Nested Listview. The Count always comes back as 0 (zero). However, if I do a watch on the nested listview variable and navigate to the Items collection, then the count is updated with the correct content. I've tried forcing a Databind() on the 2nd Listview, but that really shouldn't be necessary as I know the records are there. As a result, I am having issues Exporting the Data to Excel since only data from the Parent ListView is returned.
