View 6 Repliesyou can see the page under development at http://job1data.com:8098/admin.aspx
it looks like its setup right, the page source has the correct message for each button for the javascript:return invoked with onclick, all that was setup in the onItemDataBound routine and the delete code behind is getting invoked, i just have a message there for now for testing, so it all seems to be there, but no confirm dialog box?

View 5 RepliesHow 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?
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 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'.
I want to insert a return confirm confirmation messagebox in the gridview which fires when a row is selected. Is there a way to bring out the confirmation messagebox when the a gridview row is clicked without post back. When the user click yes, then the post back will occur. When users click cancel in the messagebox it will do nothing.

View 1 RepliesI'm using ASP.NET 4.0. Having hard times figuring out how to get confirmation from user before deleting in a DetailsView. I'm using buttons.
I did google and found Javascript code to get confirmation OnClientClick event. But it displays 'Record Successfulley deleted' no matter what you choose. Here is the code-

General Info:Aspx page holds an Ascx User control. Inside the User control, the Repeater is contained inside a View, contained inside a Multiview.
Asp.Net 2.0 framework / C#
Details:I have a repeater(inside an ascx user control) that shows records, and the first column is a checkbox. If checked, that row will be deleted.OUtside the repeater, I have a button that will deleted all rows that are checked.Everything works fine, but have been asked to add a pop up "confirm delete" message that includes the number of records that will be deleted if the user clicks "Ok" on the pop up.
Something like: "You are about to delete 8 records".
Currently my button looks like this:
<asp:Button ID="btnDeleteAllRecords" runat="server" Text="Delete all Checked Records" Onclick="btnDeleteAllRecords_Click" OnClientClick="javascript:GetCbCount();" />
I have this javascript code block:<script type="text/javascript">
function GetCbCount()
{
var cb = document.getElementById("rptrVoicemail").getElementsByTageName("input"); [code]....
I have a table with records that has delete links. Basically I followed the NerdDinner tutorial for that part in MVC. But I don't want to have the confirm view, I'd rather have a confirm dialog, and then if confirmed let the HttPost action method delete the record directly.
I have something working, but being new to both MVC and jQuery, I'm not sure if I'm doing it right.
Here's the jQuery:
I found the function for making the link POST instead of GET on the internet: `$.post(this.href); return false; And I'm not sure what the "return false" part does. I tried to modify it for my needs with a callback and so on, and kept the return part without knowing what it's for.
Secondly, the action method has the HttpPost attribute, but I have also read somewhere that you can use a delete verb. Should you? And what about the RedirectToAction? The purpose of that was originally to refresh the page, but that didn't work, so I added the window.location.reload instead in a callback in the jQuery. Any thoughts?
The Delete action method calls a couple of helper methods because it seems with the Entity Framework that I use for data, I can't just delete an record if it has relationship dependencies. I had to first delete the relationships and then the "User" record itself. That works fine, but I would have thought it would be possible to just delete a record and all the relationships would be automatically deleted...?
I know you're not supposed to just delete with links directly because crawlers etc could accidentally be deleting records. But with the jQuery, are there any security issues with this? Crawlers couldn't do that when there is a jQuery check in between, right?
How can I pop up a message box to confirm a delete, from inside a method?
Normally i would just use the following line in my button:
OnClientClick="return confirm('Are you sure you want to delete this comment?');"
However this delete method can also be called by a querystring, so I need the confirm message box functionality in the method?
[code]....
I can't click the button through code, because it doesn't fire the OnClientClick event btnDelete_Click(null, null);
I have been trying find a way, where whan a basic user wants to reset a record due to a typo.

I have a gridview control on my page that lists records and sorts them according to the most recent to the oldest record.

I'd like there to be the word 'Delete' next to the first record only.
