Can't Populate Update Parameters From A ListView's ItemTemplate
Mar 1, 2011
I am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side
I am trying to do this by something like:
[Code]....
switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.
Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem? Could I use a Repeater instead to accomplish this?
I am trying to enable server side code to check my session varible but my itemcommand is not being executed because my modalpopup is client click.Each template is loading the iframe which is horible performance killer. How do I get it to load the iframe on LinkButton click only once?
I have a ListView where I am trying to implement Updating. My update parameters are not sent to update command correctly. The value sent is the original value and ignores what I type into the EditItemTemplate. Running a trace on my SQL Server verifies this. In this example, I am only trying to modify [dedamt]. What is wrong?
I am trying to pass the value of a dropdownlist to the Update section of a listview. The dropdownlist is bound to one datasource which needs to then pass its selected value to the UpdateCommand sql for another datasource. Here is my code:
how to do this when the checkbox in listview layout template check select all checkboxes in listview itemtemplate.I dont give 'Eval 'field to checkbox present in itemtemplate.
I have a page with a gridview in which I currently populate with a stored procedure. There is an additional column I want to add to the gridview and populate (either dynamically or with a sqldatasource). Though I'm not sure how? If I create it dynamically, I don't know which gridview event to use (I would guess the rowcreated event)? Which is better or is there a better alternative to what I've proposed?
I have various difficulties handling dropdownlist in listview itemtemplate.Hopefully, resolving this example will help me understand how to make things work.I need to do several things upon DropDownList1_SelectedIndexChanged.(1) Fetch row index of listview then set the row as listview selected, or vice versa, in which dropdownlist was changed.(2) Fetch text of namelabel in that selected listview row.(3) Fetch selected text of dropdownlist in that selected listview row.
[Code]....
At the moment...(1) Label1.Text = ListView1.SelectedIndex always shows '-1' regardless in which row dropdownlist is selected/changed.(2) Label2.Text = NL.Text pops 'Object reference not set to an instance of an object'.(3) Label3.Text = DDL1.SelectedItem.Text pops 'Object reference not set to an instance of an object'.
I want to be able to get the current bound object in the ItemTemplate of a ListView control.
Here's an example of what I want to do:
<asp:ListView ID="UserList" runat="server"> <LayoutTemplate> <asp:PlaceHolder ID="itemPlaceHolder" runat="server" /> </LayoutTemplate> <ItemTemplate> //How can I get the current bound object in here? </ItemTemplate> </asp:ListView>
I was wondering if there is a way to hide the ItemTemplate. I am using listview and would like to hide the itemtemplate when i am inserting a new record. Im not sure how to or if it is possible to do.
The following code represents an EditItemTemplate in my ListView. My problem is that when I click the Update button, everything updates but then the display doesn't go to the ItemTemplate. According to Microsoft: "By default, theListView control returns to read-only mode after an update operation."
I have listview where every item has a textbox and next to it a button if you want to update the item. I want that every textbox default button(pressing enter) is the one right next to it. So i have a panel(pnlInput) surrounding the textbox(txtQuantity) and the button (btnCart). If i do nothing in code behind the default button for every textbox is the button of the item that was first rendered.
But then i tried in codebehind lstArticles_ItemDataBound //Set default button right Panel tmpPanel = (Panel)e.Item.FindControl("pnlInput"); Button tmpButton = (Button)e.Item.FindControl("btnCart"); tmpPanel.DefaultButton = tmpButton.ClientID;
But when i tried that i get the execption when the page is rendered that the default button for a panel needs to be of type ibuttoncontrol. I also tried UniqueID, but the same happens.
on SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member? When I do not put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, BC30456 does not pop up, but nothing happens when dropdownlist selected item is changed.
I want to pass the checked checkboxes value of my listview control to a second page so I can display the listview in this second page with only those selected records
this is what I am have so far , but dont really know how to get it to work the desire way.. Code is working but I am afraid that chekcbox and listview values for my loop are not correct
I have to flip or rotate images in listview itemtemplateI will catch the image id by commandargument and get imageid, and rotate it and save it back in original placei tested roate image coding , it worked perfectly. but when i combine with listview and doesnt work.
This is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton
I'm trying to do a relatively simple thing, but just cannot get it to work. I'm trying to find a dropdownlist within a ListView ItemTemplate within Page_Load.
What I want is to be able to click on the button: btnAddCart and then in the code behind retrieve the value of product name (Eval("Prouct")) and price (%#Eval("Price","{0:#}")%) for that particular row/itemtemplate.
Based on the selection of SchoolID in listviewSchools, the ListviewStudents will be filled with the data.
SchoolIDLabel is in the ItemTemplate of the ListviewSchools. The following works for insertitemtemplate
Dim txtTitle As TextBox = CType(ListView1.InsertItem.FindControl("txtTitle"), TextBox), but i can not Access a control inside the ItemTemplate of a listview.
i have a checkboxlist with a controlparameter. the flow of my page is

lblcode = MD lbldesignation = "Managing director'
3) based on the value filled in label am populating checkboxlisteps in text

i have write all the above 3 steps in textbox_textchange event.Now i wanted to know after which event, checkboxlist will populate.coz iniside the textbox_text change event when i count the checkboxitems it always says 0.but it got items.so when it will populate checknboxlist?
I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.
