Forms Data Controls :: Delete Images From Folder Using Gridview Delete Link?

Feb 3, 2010

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.

Data Controls :: GridView Last Row Delete Button Disable Functionality Not Working For Edit Button

May 7, 2015

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.

I used below code for above:


protected void Page_Load(object sender, EventArgs e)
if (!Page.IsPostBack)


problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:

Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"

Forms Data Controls :: Disable A Link Button In Grid View After It Is Clicked?

Sep 9, 2010

I have a grid view with each row as a link button. When I click on the row, some data parsing process takes place (about a 15 sec process). The grid refreshes itself at a regular interval. I want to disable the link when it is clicked once, so that the user gets to know that row has been processed already and does not click it again, until the grid refreshes itself and the row disappears. I am copying my gridview code below. how to disable the link button on that row as soon as it is clicked.

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?

AJAX :: MaskedEditValidator Outside Gridview Disable Delete Command In ItemTemplate Field

Jul 8, 2010

Something "weird" is happening with my ASP.NET application. I have a MasterPage with WebForms, and inside one of them, I have an ASP TextBox which is controlled by the MaskedEditExtender/MaskedEditValidator couple. Underneath, I have a GridView with 2 columns, an Edit ASP Command Field, an ItemTemplate which contains an ASP ImageButton with a Delete CommandName linked to a GridViewDelete Event through the OnRowDeleting attribute. The GridView is binded with SQL Server data while the page is loading.

It appears that once the page is loaded, if I want to delete a row by clicking on the ASP ImageButton, nothing appears. I have first to do something else with the GridView (raise an Edit Event for example), then it's accessible. I try different stuff to catch the source of the problem, and the "weird" part appeared when I deleted the MaskedEditValidator, just keeping the MaskedEditExtender : the Delete ASP ImageButton worked since the page loads!

A very simple question.

I am trying to delete a row from a Gridview but getting error in my Gridview1_Rowdeleting method on the line Gridview1.DataKeys(e.RowIndex).Value;

Error: Method, delegate or event is expected. Here is my Gridview

<asp:GridView ID="GridView1" runat="server" OnRowDeleting="Gridview1_Rowdeleting" DataKeyNames="RecAdvId">
<asp:buttonfield headertext="Delete" commandname="delete" datatextfield="MessageId" />
<asp:BoundField DataField="RecAdvId" HeaderText="RecAdvId" Visible="false" SortExpression="PanelId"
<asp:BoundField DataField="Advert" HeaderText="Advert" HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />

Here is my code behind method which gives error:

protected void Gridview1_Rowdeleting(object sender, GridViewDeleteEventArgs e)
int x = _Gridview1.DataKeys(e.RowIndex).Value; //Error: Method, delegate or event is expected.

Forms Data Controls :: Disable Sorting In Gridview?

Dec 22, 2010

I have a gridview that can be sorted by a few of the columns.

How do I tell the gridview to go back to the unsorted mode. That is, go back to listing rows in the order they appear in the datasource.

It's ok if this will only work the next time a rebind is done on the grid. Currently it's maintaining the sort mode after a rebind. I don't want it to do that.
