I have the following code:
<table>
<asp:ListView ID="ltvOrderDetails"
runat="server"
[Code]....
My problem is that the db item is updated with NULL values instead of values from controls.
Data entered in textboxes is not getting updated in database. In debug mode I see that textbox1 and textbox2 in ItemUpdating event contain the same values as they had before calling ItemUpdating.
Here's my listview control:
[Code]....
What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it?

I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...
<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?
I have a listview showing the data, and that i will use to Show, Edit, Delete, and Insert data.
I added a ASP.NET Ajax HTML Editor to the EditItem Template.
I click on EDIT button and it turns into the EditItem Template, i modify the data and when i click UPDATE it does nothing.
Neither updating data or turning back to ItemTemplate.
Here is its code:

And the Code behind:

i need to get data-bound items from outer listview to display in inner Listview, in this scenario:
[code]....
Where the higlighted text mean the title for outer datasource.
Data entered in textboxes is not getting updated in database. In debug mode I see that text1 and text2 in ItemUpdating event contain the same values as they had before calling ItemUpdating.
Here's my listview control:
<asp:ListView ID="ListView1" runat="server"
onitemediting="ListView1_ItemEditing"
onitemupdating="ListView1_ItemUpdating"[code]....
Codebehind file:protected void ListView1_ItemEditing(object sender, ListViewEditEventArgs e)
{
ListView1.EditIndex = e.NewEditIndex;
BindList();[code]....
What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it?

View 6 RepliesI have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my
ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?
I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
View 8 RepliesDoes anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)?

I am using nested listviews to display Sales and Sales details.

If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.
Ok, background first:
The form allows a user to create and edit one estimate.
Each estimate can contain multiple Jobs, which are represented in a ListView.
Each Job can contain multiple Parts, which are contained in a ListView that sits in each item of the Jobs ListView.
A user can add and remove as many Jobs as they want.
A user can add and remove as many Parts to/from each Job as they want.
I have no issues adding to each of these, but I do have a problem removing a single part from a single job.
For a reference, here is one Job in the Jobs ListView on the form:
I want to make sure that no matter what a user does, the part of the form they are working on saves what they have. Removing a row from that Parts ListView is no exception. What I want it to do is save the values in each of those textboxes and then delete the necessary row.
Here's what I have in the codebehind:
[Code]....
The EstimateRow variable I create does not get a value from theListView)HFERID.Parent.FindControl("LVEstimateRow") bit of code. There must be another level of nesting that I'm not accessing correctly, because it can't seem to find that nested ListView.
I have a datakey defined on my outermost ListView. When I click on a linkbutton in a row in this listview, the second listview is displayed. This inner listview has several controls and also a linkbutton. When I click this linkbutton, it gets handled by its own event; linkbutton_click. In this event all the data is collected from the innermost listviews' controls, and sends it to the database. The only thing I need within this event is the datakey from the outermost listview.

How to handle the itemcommand event for the inner listview, here is my code:

I have a listview and a dropdownlist that is pulling from an SQLTable that I am using to insert data into the ListView, which is associated with the SQLTable. For the life of me I cannot figure out how to get this thing to not allow duplicate entries into the listview.
If I could get at the data that is inside the ListView I think my problem would be solved. At the moment all the code I have is to simply find if I can at least get the data down to something I can compare, from that step I will have no problem writing something functional, at least functional for my needs. I really could use a hand with this:

I don't personally have access to the SQLTable, but I can have somebody make changes if this should/needs to be done from that end, but I would rather do it from this end in VB. I've been digging through the MSDN Libraries
I have an asp.net page with a gridview control on it but I want to allow the user to also be able to update the selected row from a series of textboxes. I simply need the code for a button click event to do this.
button is called button1
textbox is called textbox1
gridview control is named gridview1
record to be modified is in 3rd column called PlayerName
The row to be edited will always be the only record shown and will always be selected by code I've already written. I will also need to know if the record must be set to edit mode to make the button click code work.
I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
View 1 RepliesDuplicate Data in Gridview and Updating textbox in DetailsView
View 2 RepliesI am making a message module in asp.net with database of sql. i have made a gridview and enabled selecting. and a form view is synchorised with grid view on selecting. i am writing update sql but could not get a way to take data on Gridview or Formview to compare the record in sql database.

I have a gridview based on a sqldatasource that has some colums from which two colums showing the data of two fields: field1 and field2. field1 is an ID which should not be updated and therefore it is readonly=true. The sql-query from the sqldatasource is:
SelectCommand="SELECT field1, field2 from anyView"
What I want is, that when a row is updated, then the value from field1 should be copied to field2 The update-query is:
UpdateCommand="UPDATE myTable SET field2=@field2 WHERE field1=@field1"
My idea was, that the @field2 paramter gets the value from the query string out of field1:
<UpdateParameters>
<asp:QueryStringParameter Name="field2" QueryStringField="field1" Type="Int32" />
</UpdateParameters>
But this does not work. Is there an easy way to copy the data from field1 to field2 when updating the row? In addition, is this possible, even if field2 ist not shown in the gridview (i.e. field2 is selected in the query but is not a field in the gridview but should be updated with value of field1).
