Forms Data Controls :: Dynamic Delete LinkButton In ListView Error "Delete Can Only Be Called On A Valid Data Item"

Feb 22, 2010

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:

1- footer
2- Toolbar Control
3- Scrolling Data Grid with Header

ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:

ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"

Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:

Forms Data Controls :: Use LinkButton Inside Gridview To Delete Selected Username

Mar 25, 2011

I have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+"IsAdmin"(within the UserDetail table)

What I need is that by clicking this "delete_linkButton",it will ONLY delete the entire User Entity on the same row (link by the corresponding "UserName") from the "UserDetail" table,as well as delete all information from the AspNetDB.mdf (User,Membership,UserInRole,etc). I would like to fireup a user confirm,but not mandatory. At least I am trying to make it functional in the correct way.


When I click "delete" on the first row, I need all the record about "ken" inside the "UserDetail" table to be removed. Meanwhile, all the record about "ken" in the AspNetDB.mdf will be gone, including UserinRole table. I am new to, so I don't know how to pass the commandargument of the "Delete_LinkButton" to the code-behind file LinkButton1_Click(object sender, EventArgs e), because I need one extra parameter "UserName". My partial code is listed below:

Forms Data Controls :: Delete Row From ListView With No DataSource?

Apr 28, 2010

First time using a ListView control, I have it inside an UpdatePanel:





When the UpdatePanel Loads, it feeds the data to the ListView. Whenever the user clicks on a row in the ListView, a new window displaying a "note" pops up, the ItemDataBound event ties it all together. What I'm trying to do is add a button to each row so that the user can delete the row. This would call a Sql statement and then the row should disappear. I followed a couple of articles I found on ListView on how to do this, so I added a button called imgBtnDeleteNote (see markup above) and set the CommandName = "Delete", hoping that it would trigger the ItemCommand and ItemDeleting event (I have some bogus code in them, first I wanted to see if they would trigger).

The problem is that they don't seem to get triggered when I click on the delete button. All the rows in the listview disappear, and when I manually refresh the page they come back. My guess is that the events are not firing because I'm not using a DataSource object in the aspx code, but I'm not sure.

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?

Nov 18, 2010

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";

But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.

Specified argument was out of the range of valid values. Parameter name: index

How do I reference the delete button so the edit button is not affected in this case?

Forms Data Controls :: Have A Grid Contol That Allows Delete What Would Like To Have Is Someway To Say Are You Sure You Want To Delete?

Feb 8, 2010

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.

runat="server" CausesValidation="False"
OnClientClick="return confirm('Are you sure you want to delete this record?');"

Here is my code: You can see where I added the code from above.

ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />

Forms Data Controls :: How To Insert Delete Confirmation Dialog To Gridview Delete Button

and I added this as a Gridview column:


and this is the error I get:

Forms Data Controls :: ListView Delete And Object Reference Not Set

Feb 18, 2011

I keep getting Object Reference not set to an instance of an object errors when I try to use the ListView delete function. It is a fairly freshly created listview and is very close to the original template so not sure what is going wrong. Some possibly relevant code:


I also put in a breakpoint in the deleting event (only reason I added the deleting event) to look at the status of everything. When I do: Contact delContact = (Contact)e.Entity; and look at the values, the values for almost everything are set to null. It does have the correct value for the ID of the contact object that needs to be deleted. When I continue to step, it jumps to my designer.cs file and appears to break here:


likely because _Case_ID is null. The exact exception I'm encountering is: System.NullReferenceException: Object reference not set to an instance of an object. While I could probably re populate the object with correct values, that doesn't seem likely to address the real cause of the problem.

I'd like to write somethingthat would get the selected index from a different control, like a listview, and then delete from the sortedlist. I've read up on a few examples on how to bind data from a sortedlist to a listview, but I've not seen an example of how to get the index once the data is displayed! Can this be done?

Forms Data Controls :: Delete Selected Item From DataTable Using LINQ?

Feb 1, 2010

I have a ListView which I populate using DataTable.

In each row I have a delete button. When the user clicks on the delete, that particular row is deleted in the DataTable Table.

After I perform the delete, I want to avoid page reload just to populate the ListView with the new set of records without showing the deleted row.

I suppose LINQ is the best choice for this. But I am unable to implement it.

Databinding - How To Delete An Item In .NET Listview And Persist The Datasource

Apr 27, 2010

I have a collection of objects I bind to a Listview like this:

if (!IsPostBack)
List<Equipment> persons = new List<Equipment>
{new Equipment{ItemName = "Sworn", ItemCount = 7, ItemCost = 255}, [code]....

I want to Add/update/delete from this object collection and submit the final data object collection to the BL when the user saves... Rather than just delete/add/update everytime a row is changed.So my question is how do I maintain state for that datasource? I have tried this (delete example)

protected void lvMain_ItemCommand(object sender, ListViewCommandEventArgs e)
switch (e.CommandName)
case "Delete":

But it does nothing. I can't rebind it to the datasrouce because at this point the datasource is null.. I assume the listview keeps its own view state which contains the data?... I guess worse case I can always hold the Object Collection in a Session object.. ..
