Disable A Button If The Required Page Has No Data?
Oct 19, 2010
I have the following scenario and I'm not sure how to go about in resolving it. Any ideas would gratefully recieved.I have a page(A) with a button that when selected opens a new page(B) with a populated gridView.However if the gridview hasn't got any data to display, rather than use the <EmptyDataTemplate> within the gridview, I'd rather use disable/lock the button on page(A) thus preventing access to page(B)Is this possible? How on earth would I go about such a task ?
I built a simple application that is used to manage photos for an image gallery on my employer's website. A user can add, edit, or delete items which are stored in an XML file. I've set up Up/Down buttons so that I can move pictures up and down in the order.On the first page, I've disabled the Up button of the first item on the RowDataBound event... since it's already first
[Code]....
I'm trying to do the same for the Down button on the last item of the last
I 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.
IÂ thing using Enabled property we can do. How to proceed. Is there any other way to do it.
<asp:LinkButton ID="LinkButtonExport" Text="Export to Excel" runat="server" OnClick="LinkButtonExport_Click" />
am creating a web application in using c# with asp.net.
in that am using login page only as normal aspx page. other pages are using masterpage.
when i click logout button in masterpage. page will redirect to login page. after that if i click browser back button it was moving to previous page. how can i prevent this.
am using this following code in master page aspx page. And My log out button code is below.
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.
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"
doesn´t work for me because the button does not postback. Is there an easy way to prevent a second click while still keeping the functionality of the button?
I have read that you can not disable the back button on page load but I can clear the cashe on page load so the back button would then be greyed out. I have read a few articles on this and I am unable to get it working. I am using MS visual web developer 2010.
I have a webform where I have validators and submit buttons.WhatI am looking for one of my button is1. When its clicked, if all the validators are satisfied, 2. If all the validators are ok, It should disable the button for postback so that user cannot click it again during its process ( means during postback )3. it should enable back after postback if possible otherwise I can do it from code behind at the end of my process,
my question is very simple. I had read through many post include this: http://blog.anasghanem.com/post/How-to-get-the-readonly-textbox-value-on-the-server-.aspxI have a calender extender and the date was target to a texbox. This textbox, i had set it to readonly and it is validate by a required field validator. so mean this texbox must have a value inside. my prob is, i bind the textbox to database and if data is NULL or empty i can't save it because the required field validator was validate textbox as empty value at cllient side. If i remove the required field validator everthing fine. But this is not i want. I have try to set the textbox to javascript onCopy,onPaste,onkeyup. but user also can delete and paste into the textbox.i have think to disable the requried field validtor at server side when data is inserted.
In my web page I have a Checkbox (datatype = tinyint/boolean) and 2 Required field validator (whose visibility is false). I want that when I check(tick) the checkbox, then required field validator visible = true, else not.For this I tried this code on Page_Load as well as on save button click, but it is not working:
I have a pager template in a formview which shows the Prev, Next button and the number of pages. I want to make the Prev or the Next button disable when there are no more pages to go. Like, if it is the first page, then the Prev button will be disabled.
i ve a grid which shows a large no of records, wen i press save button before loading all data then it through exception.... i want to disable my save button util all data is successfully loaded in grid. after that i want to enable save button
I want a solution for checkbox Check changed.in my gridview when i check on any row it hits check changed event and i have made a button visible if atleast one checkbox is checked.(But when i uncheck i want the button to get hidden if no row is selected).
I have been trying to get a Gridview of a list of usernames and passwords for site login that the Edit button would be disabled if one of the columns had a certain word in it?
For now, I need the Edit button to be disabled if the Username for a record is "admin". Is there a way to do this? My current code is here:
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.
