I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?
I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.
I have a modal formview with insertitemtemplate. I have to click the insert button twice to fire the event.
But if I do not insert any values, only one click is required and the validationgroup fires. But if I enter all valid values, I need to click twice and the event does not fire during the first click. But I need CausesValidation = false because to required field validators.
How to avoid two clicks to fire the event if the formview is valid
i am developing an ASP.NET website, i have a datalist that contains an item template with hyperlink in it, i want to access the hyperlink clicked i tried "SelectedIndexChanged" event, i don't know what to do. here is the code <asp:DataList ID="DataList1" runat="server" DataKeyField="album_id"
I've constructed a simple horizontal DataList that will contain 'N' number of items. I'm now trying to wire it up so that when the user clicks on any item a server-side event is fired. To accomplish this I'm following this article: [URL]
i have datalist and on button click event i check the checkbox is checked or notfor this my code is
<asp:DataList runat="server" ID="dlstproductsize"> <ItemTemplate> <input type="checkbox" value="<%#eval("size_id")%>" id="chksize" runat="server" /> Â Â <%#Eval("name")%> </ItemTemplate> </asp:DataList> If chkallowsize.Checked = True Then For Each item In dlstproductsize.Items If (CType(item.FindControl("chksize"), HtmlInputCheckBox)).Checked = True Then ocommon.ProductMapingInsert(uniq_id.Text, CType(item.FindControl("chksize"), HtmlInputCheckBox).Value) End If Next End If
i get the error like object reference not set to the object
Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)
I try to add a new ImageButton to my panel in a dynamic way -when the user click on button in the page.When i create the ImageButton i register to the click event.when the page load - i can to see the ImageButton but when i click on him is not fire the event.

I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I have a datalist in my page that has a LinkButton at the beginning of each row that, when clicked, fires the Itemcommand ("select"). There is no issue with this as it works as it should:
[Code]....
But I also thought it would be good if the user could simply click anywhere in the datalist to expand the item and show based on the SelectedItemTemplate. So, I thought, the cleanest would be to add a function in the code behind that adds a click event to the Panel "panItem" that clicks the above mentioned LinkButton like this (fires in Page_PreRender):

Here is where the problem comes in. This works great in IE but not FF3.6 (havent tested it with older version of FF). In FF, I get a JS error saying "dlMapDB_ctl00_btnItemFigNumber is not defined" for the first row, "...ctl01..." for the second row, etc. So the IDs are correct based on the markup (which makes sense since it works in IE).
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.
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
When i Click Twice in Calendar Cell Date That Make The Event Fire only one time for the first click but the second click not fire the Event CalendarSelectionChanged ... In my Logic i want The Event Fired every Click Even if the clicks happened on the same Cell.
