Forms Data Controls :: OnItemCommand And OnItemInserting Events Of ListView Is Not Firing?
Oct 4, 2010
I have a nested listview (orders with products)I want to add functions to update products and option to add new products update func works fine. wheni try to insert new record, itemcommand and iteminserting events are not firing. Im registering dynamic script using the below code
imgPicker.Attributes.Add("onclick", "LoadLookupScreen(" + clientIDs + ")");without the above code, itemcommand event works fine. when i add this script register itemcommand event was not firing
I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.
I'm having some real problems trying to do this. In simple, a table shows a list of rooms with details of the room in each column, extracted from a database. The there is a button in the repeater, which is supposed to tell me what I clicked on in a new label. However the OnItemCommand just doesn't seem to be working.
[Code]....
Right now I'm just trying to get it to work, so that when I press the button, it causes the label to say "It works". But it just doesn't want to work.
I have a templated user control with single instance template attribute. It works great for everything except the following scenario:
[Code]....
The folder selector uses a tree view that allows people to select a folder, its FolderSelected event works perfectly and the file selector updates with the files. The file selector has a repeater that lists the files in the selected directory. It has a linkbutton for each of the files so that the user can select a file. The problem is that the ItemCommand event of the repeater doesn't fire when the file name is clicked on. The page performs the async postback like it should, but in debug, the method to handle the itemcommand event is never hit. On the same user control to select files there is a button that the user can add files to the folder. When it is clicked, the event DOES fire and the file is added and the control refreshes in the update panel, everything perfect. It seems that because the linkbutton is already in a templated control (which is in a user control, in a templated control), the event isn't firing correctly. I am confused as to why this should be a problem, especially since all the other events (even the custom ones) fire as long as they aren't in another templated control. Since the code is complicated, I didn't want to post it all here.
I am having a DataGrid in one usercontrol which is getting filled with some data when I press some button(ouside it). This Datagrid is filled by one linkbutton also. When I click this LinkButton then OnItemCommand or SelectedIndexChanged should fire, but both the events are not firng. While the control's PageLoad event is firing.
I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event.. [Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box
controls.Once the datagrid binds then the events in the aspx page not firing.Issue occured when the number of rows greater than 500.The number of rows less then its works fine.
I am using ListView Control to show multiple images and my requirement is when i click on any image then it should go to the correcspoding page. For this purpose i am using onItemCommand event But i am unable to create the corresponding page link so that i can use them for redirection.
protected void listViewParentService_ItemCommand(object sender, ListViewCommandEventArgs e) { int id = Convert.ToInt32(e.CommandArgument); if (e.CommandName == "LnkViewService") { // i dont know how to create } }
i have following corresponding pages on that i have to redirect on the click of image
I've got a listview and I've put a button control in one of the columns, I'm trying to figure out how I have listen to the button click within a certain row, but can't see the button in the dropdown for the IDs I can generate events for.I'd like to get the primary key of the row that's been clicked on and then run a sql statement against it.
I have a problem with listview and I can't find any useful solution.
Here is my situation:
I have a listview with insert row and i need to do some calculations as user types in. Some fields are not filled by user but computed by javascript function (they are not inserted into db, they are shown for informational purposes only). These fields are just textboxes - computed ones are disabled. So i want to add some javascript functions to handle the computation, but i need this functions to have proper IDs. So i add them dynamically on listview.itemcreated with attributes.add. And that's where the problem begins.
If I use textbox.attributes.add("onblur", "some code"), suddenly all row commands of insert row stop working. They seem to cause a postback (all filled fields are blank after) but they are not firing any event. ItemCommand, ItemInserted, ItemInserting... Nothing. I have a masterpage and updatepanel in my website but i don't think that is the source of all problems. If I clear all javascript events from all textboxes and dropdownlists, row commands are working again. But I really need some client side computation and validation and I don't know how to make it work and still can insert rows.
I'm using a listview control to do a survey stuff. Everything is working perfect to present the data questions, to be answered text with the different type of controls radiobuttonlists, checkboxlists, dropdownlists, etc. The admin can modify, create, change questions, answers, etc. on the survey.When it's select, edit, or insert it's easy to find the control inside a listview.However, I'm wondering how to post user's answers back to DB. How to find controls inside the listview to grab the entered data/responses from there using let's say the submit button that is outside of the listview.I believe there should be a way to do it as otherwise why we put radiobuttonlist on a listview that somebody could click it and then we should be able to get that entries. Or I'm too optimistic on this control?
I am building a query tool which displays the results in a dataGrid. when the results are displayed (buttonColumn) it should allow the user to click a row and execute another function. the columns selected in my query are not always the same name but it is user defined, therefore i am not able to define the columns in the ASP page, but insted am doing it in the C# class behind. When the table is generated it does have the button columns but when clicked it does a postback and it does not execute the function defined in the OnItemCommand tag.
I have a DataList in an UpdatePanel. I'm using a PopupControlExtender for the UpdatePanel. On the DataList I have an OnItemCommand wich doesn't fire and I cann't figure out why.
I have a gridview that's inside a .ascx control that's dynamically embedded into another .ascx control, which is then called by a web form. The gridview will initially bind, but when any paging/sorting/command events are then triggered, I can't get any breakpoints inside the events to kick off. Additionally, when I look at the code-behind in the now-blank page, I see the old data sitting there.
what on earth is going on here? For edification, the .ascx page with the control is excerpted.
I will go into the background of why i am wanting to do this if necessary but in short. I want to create a WebControl which has a button on it. I provide the most simple of examples to understand why it is not working.
No matter what i try my button event doesnt seem to fire. the code for it is here:
I'm facing a weird issue...My button events are not firing :(I'm using the 3.5 .net framework and I've already tried to run aspnet_regiis -c, clear the browser temp files, use windows integrated authentication, but nothing works...this is the cenario:
- windows server 2003 - app migrated from .net framework 1.1 (which was working fine) to .net framework 3.5 - IE8
I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
I have a user control which I load dynamically using LoadControl. In this UserControl I have a button with assigned OnClick event, but when I click that button, the event is not fired. I'm populating the user control in UpdatePanel's Load event (I invoke __dopostback from JS).
I have a button that adds a product to my shopping basket. it has a postbackurl="../shoppingbasket.aspx?productID=1" when the page is loaded I get the querystring (ProductID) and add it to my database. Well I have been watching the database and I can see that in 1 day the whole of my product range has been added to the shopping basket, not only that but every time it fires the event it creates a NEW basket thus messing up my shopping basket ID's.
So my question is, I want the search engines to index my product pages, BUT I do not want then to add to my basket ( i.e. firing the postbackurl ) I have tried may things like rel="nofollow" adding the URL to my robot.txt. I don't really want to use recaptha as I have do before and have many complaits about it.
I am in a deep deep trouble because I am trying to use web parts in my project,I have implemnented custom provider for personalization(coz, I am using MYSql as a database).I am using three web part zones and each zone hve more than three controls and whenever I try to drag and drop the parts from one zone to other zone, for the first time the droped element successfuly runs but after then if we again try to drop another element from other zone to this then the already dropped element goes to its original place from where it is dropped,The 2nd problem is that close and minimize verbs are not firing well, e.g if there,My provider personlaization class is as,
I've dynamically created 3 checkboxes as you can see in the code below. I also wrote an event handler below. When I run the code, the 3 checkboxes show up, but the event handling does not work right. Whenever there is postback from any of the 3 checkboxes, Label1 reflects the state of checkbox #3, no matter if I toggle checkbox #1 or #2. I put the code I have under Page_Init into Page_Load instead, but makes no difference either way.
The bottom line is, I want the event handler to know exactly which of the 3 checkboxes is firing the event so that Label1 can reflect that.
I have a table control that I am building dynamically and inside one cell I am placing a LinkButton inside it and wiring up an event. Although the event for the LInkButton never fires.
