Data Controls :: Delete With Confirmation Using Details View Delete Command Button
Nov 7, 2011
I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

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?

I have a confirmation button that appears when an end user highlights a Customer Name and clicks the link to delete. The confirmation prompts: "Are you sure you want to delete this record?"
Here's the code from the .aspx:
<asp:LinkButton ID="LnkBtn_Delete" runat="server" Width="100%" CommandArgument='<%# Eval("CustID") %>'
CommandName="Delete" Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this record') "></asp:LinkButton>
What I'm attempting to do is replace the portion of the confirmation question "this record" with the actual Customer Name.

I have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
[code]....
However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.

I found ways to add a delete confirmation box with a delete buttons, however, I'm using a delete command field to delete my rows, Is there a way to add a delete confirmation within the GridView_RowDeleting method, or should I just use a regular button in a templateField?

I have both a details view and gridview with deleting enabled. I'm concerned about users accidentally clicking delete, and poof, the record is gone. Is there a setting to get a confirmation message before the delete is actually done?

I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.

I'm a novice programmer and I have this situation: I have a nested Gridview, and I want to be able to DELETE the records in the nested Gridview. I have no problem inserting new records with the nested gridview, but it does not execute the DELETE Command on the SQL Datasource. I checked that the DATAKEYNAME on the nested gridview includes the the parameter that is used in the DELETE SQL Command on the SQL Datasource for that Gridview. But it seems to me that the parameter value is not being passed to the SQL Datasource by the nested gridview. Maybe I need to use a difference approach to execute this on a nested gridview compared to a regular gridview.

Within my ItemTemplate on a listview i have a link button carrying out a delete command. As it's a custom command i use the ItemCommand to do the deleting and have a stub itemdeleting.
It works fine set out like this however i only want the delete button to be available to logged in users. If i wrap the linkbutton in a loginview and then click on it the ItemCommand and ItemDeleting never get called the page just refreshes.

Here we have a function The 'ConfirmDelete()' which is executed each time a click event occurs on the page.
2. Then we use a logic that to find which element was clicked on i.s we append a word 'DELETE' to the ID of the control.
3.And finally check if the clicked element having ID is 'DELETED' , then the javascript function will be execute to ask the user about his/her confirmation.

I'm using the asp.net membership on my website. On the User Administration page i've got a GridView to show the details of the users on the site. As a datasource rather than just using the Membership.GetAllUsers function i've got a SQLDataSource as i need to display user information from 3 different tables. I'm trying to add a delete button to the GridView. I'm setting the Membership's UserName as a DataKey and then using the RowDeleting event to call Membership.DeleteUser for the appropriate UserName. This works fine and the user is deleted however i then get an error showing up that "Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified."
I don't want to use the SqlDataSource for deleting as i've already done it using the Membership. How can i stop it from trying to do this? Here is the cut-down that i have if you're interested. The selectcommand in the sqldatasource was auto-generated by it.

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"

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.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />
<asp:linkbutton id="NewButton" runat="server" CausesValidation="False" CommandName="New" Text="New" />
