C# - Add Controls Dynamically To A Listview?
Jan 19, 2010
I have an asp.net listview. The data that populates it is sorted into groups, and i'm using some code in the listview item template, that essentially checks if the grouping field has changed in the data, and if so it prints a new row, with the heading, so it looks a bit like this:
<ItemTemplate>
<%# AddGroupingRowIfWPHasChanged() %>
<tr id="row" class="GridViewRow" runat="server" >
<td valign="top" align="left" ><%# Eval("item1") %></td>
</itemTemplate>
This works great. However now I need to add a button the the group heading field, and I can't seem to get this to work. Obvioulsy this button only needs adding if the heading has changed, but the AddGroupingRowIfWPHasChanged() method does not seem to have access to the current ListviewItem, so I can't add a control.
how I can add a control to a list view dynamically, depandant on whether its a group heading or not?

Does anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.

I am having trouble getting the input values of dynamically created controls in a ListView.
Here is my ListView:
[code]....
The textbox is found, but there is no value. It's like I just wrote over the textboxes with new ones in the previous block. If I remove the previous block of code no textboxes are ever found.

I have a listview that displays a list of textboxes that get created on a button click. I would also like a label to be created next to each txtbox that would increment what is says from step x: to step x+1:
Do I need to create another listview control for this, or is there a much easier way (which I hope)?
Here is the current web code for my listview:
<tr align="center" valign="middle">
<td>
<asp:ListView ID="lvDynamicTextboxes" runat="server" ItemPlaceholderID="itemPlaceholder" onitemdatabound="lvDynamicTextboxes_ItemDataBound">[code]....
And here is the code-behind
protected void btnAddNewStep_Click( object sender, EventArgs e )
{
this.UpdateDataSource();
this.IncrementTextboxCount(); [code]....
EDIT::Since there seems to be a bit of confusion, I'll try to clarify:As of now, I have a textbox in a listview with a button underneath.
________
| txtbox |
|________|
_____
|_btn_|
When you click a button, it generates another text box, so clicking it twice results in this:
________
| txtbox |
|________|
________
| txtbox |
|________|
________
| txtbox |
|________|
_____
|_btn_|
These textboxes are to create steps in a process, so all I would like to do is add a generated label next to each generated textbox to say which step it is. So I want it to look like this:
________
["Step 1"] | txtbox |
|________|
________
["Step 2"] | txtbox |
|________|
________
["Step 3"] | txtbox |
|________|
_____
|_btn_|
And if they click the button again, then another label is generated with the text "Step 4"

I have a listview control which is created dynamically, it is nested inside a repeater's itemtemplate. I'm trying to attach a datapager to it, which is also created dynamically but the datapager will not display and the listview will just display all its records in its entirety.

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.

I'm trying to check dynamically generated "checkbox" value inside Listview.
I can reference non-dynamic checkboxes exact in same location (index) inside Listview using "e.Item.FindControl", however I can't reference dynamic checkboxes.
Here is my code.

I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

I want to hide show some columns based on criteria, so I have ItemDataBound event, but I don't know how to get the actual listview row so I can do things to do it.

A have a ListView that is rendered with multiple items. Now I want to toggle some HTML attributes with JQuery. Therefore it would be best to have access to these elements via an unique ID.
But trying to create a "dynamic" and therefore unique ID by
<tr runat="server" ID='<%# this.GetUniqueID() %>'>
</tr>
results in an error that tells me that the ID needs to be simple and cannot be set by a call to a method.
I know that I can dynamically create controls in the code-behind and set the ID there. But in this case, I'd rather like to let the content be rendered by the ListView itself.
That brings me to the conclusion that the idea of setting a dynically ID in the Template is totally wrong. How can I achieve the desired behaviour?
Edit: Ok I just found out, that I can set the ID with a BindingExpression, like
ID='<%# Eval("MyColumnWithUniqueID") %>'
Still, is there another, or even better solution to this?

I'm trying to create checkboxes inside Listview from code behind, but I'm having problem creating them.
What am I missing here?
Checkbox's ID comes from Datareader.
Here is my code.
If reader2.HasRows Then
While reader2.Read
Dim jobid As String = Convert.ToString(reader2("JobTicketID"))
Dim jobtitle As String = Convert.ToString(reader2("JobNickName"))
Dim item As ListViewDataItem
For Each item In ListView1.Items
Dim jobtd As HtmlTableCell = CType(item.FindControl("jobtd"), HtmlTableCell)
Dim jobtr As HtmlTableRow = CType(item.FindControl("jobtr"), HtmlTableRow)
Dim cb2 As CheckBox = New CheckBox
cb2.ID = jobid + "cb2"
cb2.Text = jobid + IIf(jobtitle <> "", " (" + jobtitle + ")", "")
jobtd.Controls.Add(cb2)
jobtr.Visible = True
Next
End While
End If

I 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?

I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :
[Code]....
C# Behind Code :

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.
