How to handle the itemcommand event for the inner listview, here is my code:
I try to datbind a listview which is inside another listview InsertItemTemplate.
I'm binding the listivew in the parent listview onitemcreated events. I receive the error Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
I am loading the autocomplete extender properly but I need the PK from the selectedValue. I have looked at other examples and they do NOT show how to drill into the tabcontainer, then drill into the listview, and then locate the extender value. Here is what I have so far. My "TABCONTAINER" value shows the extender correctly but I am unable to locate it.
I have a listview that is showing its result by using a linq query. The linq query goes like this.
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
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?View 8 Replies
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.View 1 Replies
Is there any way to enable alternative ListView (LV2) or any other control in case when ListView (LV1) returns no records from DB? I already have emptydatatamplate designed for this case, but I need to enable a new ListView below in this particular case and I don't know how to achieve this!View 2 Replies
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 :
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:
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.View 6 Replies

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?View 3 Replies

I'm trying to do a validation for checkboxlist on a server side as all java approaches didn't work. However, probably due to the checklistbox is inside a listview the FindControl is empty. how to find a control inside a listview on a button click event when the button is outside of the listview.
ErrorMessage="* Please, select at least a one checkbox."
Sub cblCustomValidator(ByVal objSource
ByVal objArgs As ServerValidateEventArgs)
Dim chblAnswers As CheckBoxList = _
If CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
Then 'it's not working here as it cannot find the control inside a listview
Dim boolFlag As
Boolean = False
For Each li
As ListItem In chblAnswers.Items
If li.Selected Then
boolFlag = True
If boolFlag Then

I have a listview and inside the listview I have a gridview. I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button. I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works. But if I rebind this gridview, nothing happens.
I can trace through the rowediting and everything is working. It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening? Why isn't my rebound edit mode gridview showing up?
I have a ListView with a checkbox field inside that gets the id set dynamically.
I also have a button that when pressed needs to check if any of the checboxes have been checked but I'm not sure how to get this done.
This is my code:
see the following code. How do I access the imageButton (or any other control I may happen to have) within the listView? In this case, I'd like to change the image of the imagebutton based on certain conditions in the code behind file while the listview is being populated.
I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.
A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing
A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)
