View 1 RepliesUsing "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.

How can one disable a Link Button in gridview. In gridview, I had defined linkbutton as :
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkbtndownload" runat="server" CssClass="Links" CommandName="DownloadPdf" CommandArgument='<%#Eval("Client_ID")%>'>Download</asp:LinkButton></td>
</ItemTemplate>
</asp:TemplateField>
The delete link on my gridview deletes the previous row instead of selected row....Also, it doesnot delete the already existing rows. When I add new rows and try to delete them then my delete works that too incorrectly.
View 5 RepliesI have Link Button to Export to excel in Master page. Since I have placed it in master page I can see Export link button in every page. I need to disable link button where gridview is not present in a page.

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:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
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"

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.

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?

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!
I have a site where I use a User Table. I want to be able to add users but not delete them - I need to update a filed in the database that said Is Deleted

I have a gridview control on my page that lists records and sorts them according to the most recent to the oldest record. The most recent record is first record at index 0, and I want the users to be able to only delete the first record in Gridview. Is this at all possible?

View 5 RepliesI 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.
