I'm wondering if anybody has run across something similar to this before. Some quick pseudo-code to get started:
[code]....
The main thing to take away from the above is that I have an update panel which contains a listview; and then each of the listview items is contained in its own update panel.
What I'm trying to do is when one of the ListView update panels triggers a postback, I'd want to also update one of the other ListView item update panels.
A practical implementation would be a quick survey, that has 3 questions. We'd only ask Question #3 if the user answered "Yes" to Question #1. When the page loads; it hides Q3 because it doesn't see "Yes" for Q1. When the user clicks "Yes" to Q1, I want to refresh the Q3 update panel so it now displays.
I've got it working now by refreshing the outer UpdatePanel on postback, but this seems inefficient because I don't need to re-evaluate every item; just the ones that would be affected by the prerequisite i detailed out above.
I've been grappling with setting up triggers, but i keep coming up empty mainly because I can't figure out a way to set up a trigger for the updatepanel for Q3 based off of the postback triggered by Q1.
I have a two usercontrols sales and salessearch. they are inside two tabs. I want to refresh the contents inside the tabs when i click in the tab headings, which are basicaly <a> tags. Right now when i switch between tabs I have no way of updating them.
How do i make the tabcontents refresh when i click on tab headings.
Following is the code...
I use a javascript function selecttab() to switch between tabs.
I'm trying to implement Google Interactive chart inside an updatepanel.
The regular Google Charts do work (I think because there I'm just calling an URL).
But now I want the interactive chart inside an updatepanel within a tabcontainer etc. But now the request to Google is made, resulting in an infinitely loading white page to Google.
I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.
I try to datbind a listview which is inside another listview InsertItemTemplate.
[Code]....
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 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?
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 need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.

I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.
I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* 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.
[Code]....
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):
[Code]....
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 div with id="myDiv" and runat="server" inside a listview with id="lvItem".I need to access the div in code behind to add width of the div at runtime.How can I access the div from codebehid using C#?
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 the OnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)
I'm trying to get paging working on the listview. I thought that it would display the paging controls, and just page through them normally.
It does display the controls, and limits the result set shown to the appropriate number of records (pageSize) but when I click on the paging controls the grid refreshes and nothing changes with the nested listview (it's still on the first page).
I've tried nesting the listview inside an updatepanel, but the behavior remains. The gridview itself is already in an updatepanel.
I have a page with a listview that shows something like posts. On each post there should be a "rate box" which works similar to the "Like" button in facebook. The rate box is a User Control, that has an update panel inside it.
If I put the control with some random values in the page it works great - but when I put it inside the ListView, where it should be located, it won't work. The method is being called, but nothing happens.
I simplified the code a bit to make it easier to understand:
[Code]....
While debugging I noticed the controls in the method "OnRateClick" are empty and don't contain the right values.
Does anybody have a working example of a cascading dropdown inside the insertitem and edititem templates of a listview? I have been working on this for a couple of days now with only marginal success, and I fear I will have to abandon work on this due to time constraints.
The areas where I'm having difficulty are:
I just have two dropdowns(dds). In the insertitem row, I am able to have the user choose from dd1 and set a value in dd2. This works fine, but the user must be able to go back and change dd1 and have the proper value set as a selected default item in dd2. I can't get this to work.
In the edititem rows, I'm having difficulty setting the selected value of the dropdowns when displaying the row to be edited, and am running into the same problem as above when the user changes a dd1 value - the dd2 value does not reset to the proper selected default item.
My strategy for the edit items has been to try to get elements from the dataset bound to the listview to flow to the web service routines as contextkeys. I then iterate through the data values to be displayed in the dd and if the value = contextkey value, then set its isDefaultValue to true when adding it to the list of CascadingDropdownNameValue items.
The solution needs to work in the real world. That means Master Pages, so any fancy javascript workarounds need to take this into account.
i have list view and inside lisetview i have another list vie like nested listview lv1 --> lv2 and inside lv2 i have button when i'll click buttion than insert template show but how can fine control lv2 ....? there is my code Lv1 is working but lv2 is creating problem..?
I have a page that has a TabContainer to present and edit various pieces of information. On one of the tabs, there is a ListView control that allows in-place editing. The ListView works great when it is not contained in the tab. When it is in the tab, the Edit button works, but once it is in edit mode, none of the buttons will fire (update or cancel). Does anyone know of a conflict between the TabContainer and the ListView controls? I am thinking that I might try out jQuery UI to see if the tabs work any better.
