Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?
Nov 18, 2010How 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?

CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"

MVC :: How To Use AntiforgeryToken With Delete Action Link
May 27, 2010i am currently working on an asp.net mvc 2 web app and would like to add some ajax functionality on my delete item actions.Show, on the list items displayed view page, i wrapped the list items inside a partial view and added an ajax delete action link for each item (inside a foreach loop):
[Code]....
On the AjaxDeleteItem ajax controller action, i delete the selected item and redisplay the updated items list (via UpdateTargetId = "divList", where the list items partial view resides).My question is how i could insert Antiforgery token in such a scenario in order to secure delete operations from CSRF and XSRF attacks.
Ajax Update After Delete Action On Index View In ASP.MVC
Jul 14, 2010I'm trying to do an Ajax delete in a fairly standard Index few, i.e. I have a generated Index view with one added filter drop-down, of little relevance here. I have changed the free Delete Html.ActionLink on every row to an Ajax.ActionLink, and the delete and ajax update work, but whichever container div I try and update, I always somehow get some kind of nesting in the updated page, e.g. after a delete and update, I get duplicate Home and About links from the master page inside my content. Here is my current action link that causes what I describe above:
<%: Ajax.ActionLink("Delete", "Delete", new { id = item.InstallationDBNumber }, new AjaxOptions { UpdateTargetId = "jobList" }) %>
... and here is where jobList is located, just outside the table used for the index list:
<div style="clear: both;">
</div>
<div id="jobList" class="index-list">
