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.

I have dropdownlist which items are generated using SQLDataSource. And there is a "Delete Button" next to it. When user selects item from dropdownlist and presses that button I want the item to be removed from DB. Here is the question "How can I achieve this using sqldatasource Delete Command?" I do can remove Item From Code Behind. But i believe it's more efficient to use sqldatasource delete command.

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:

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

I am trying to delete row(s) from the DataTable conditionally but I cant.
Actually I have DataList with CheckBox (default value checked=false). I am bindind DataList at run time using DataView (Dataview is created fromDataTable).
I also have <asp:Button ID="btnDelete" ....> which I am using to delete checked items in the DataList (But this functionality is not working).
The user first "checked" items in the DataList and click the the button "btnDelete". Here nothing is being deleted (?) and the DataList appears with all the items"unchecked" (even those which the the "checked" by the user). protected void btnDelete_Click(object sender, EventArgs e) . In this function I am checking state of the checkbox before deleting the row in the DataTable.
On PostBack generated by the "btnDelete", DataList appears with checkboxes unchecked therefore nothing is being deleted
Here is the DataList

Following is the .cs file

I have a gridview with linq and in the itemtemplate I have a column like this :
Bind("SUPERFICIE","{0:N00}")
If I display my gridview, I have this kind of value : 6'555
When I delete this row I have this error :
Failed to define one or more properties of type DS.MY_TABLE 6'555 is not a valid value for Decimal.
Apparently, when I use a format on bind, it change my values in my ds and I cannot delete my row!
I don't understand, because in my logic with the bind format I don't need to correct some formats for delete a row !

I have a link button that I want to function as delete. I have to do it this way because I want confirmation before allowing deletes. In my debugger, I flagged this block of code and run it line by line. For some odd reason, it thinks my selected row. Maybe I'm overlooking something? Here's my code behind source:

I have a DropDownList on my aspx page and wanted to add ListItem programatically. The item will start from 2 years ago to 1 year later (e.g. from 2009 to 2012) so if the year change, it will be automatic. I also want the current year to be selected by default.
In the code behind, I did this:
For i As Integer = (DateTime.Now.Year - 3) To (DateTime.Now.Year + 1)
DropDownList1.Items.Add(i.ToString())
Next
DropDownList1.SelectedItem.Text = DateTime.Now.Year
As result, I'm having the items in this order: 2011 (selected), 2009, 2010, 2011, 2012. The 2011 is duplicated (I wonder why). When I view the source page on Internet Explorer, I have this:
<option selected="selected" value="2011">2011</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>

have a nested listviews:
Listview1-Item1
<if Listview1.selected index = 0>
Item1NestedListView - item1
Item1NestedListView - item2
When a user selects an item in the parent listview, the nested listiview displays as part of the selected item template - when a user selects an item in a nested listview it correctly populates a third, separate listview. To make sure I'm being clear, I have a parent listview with many rows and each of those rows has a nested listview, that is only populated and displayed when the row is selected. The parameters for the nested listview are set in the ItemDatabound event of the parent.
I had this working fine when both objectdatasources were on the aspx page. However, requirements have changed and we would like to pass a class to the BLL. I cannot figure out how to do this using a datasource on the aspx page. I can pass a class doing a databind in the code behind. However, if I do the databind in the code behind, the SelectedItem template does not get displayed as I would like. I need to find the the selectedIndex for the parent listview in SelectedIndexChanging. however, when I click or 'select' an item in the parent listview, the page refreshes, the ItemDatabound of the parent of the parent fires NOT knowing the selectedindex, then the SelectedIndexChanging event fires changing the SelectedIndex. By this time the Listview is already on the screen without the selectedItemTemplate containing the nested listview. If I click on another item, the when the page refreshes it knows the selectedItemIndex chosen before and displays that SelectedItemTemplate containing the selected index.

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.
[Code]....
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 asp.net, 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:
