GridView_RowCommand Event Fired Again On Page Refresh?
Jan 28, 2011
I have implement GridView Row Editing feature in my .net application using <asp:CommandField.
I clicked on Update button to save the record after editing the row.Now if i refresh the page or press F5 GridView_RowCommand fired again. How can we avoid this.Is there any mechanism to identify when user press F5 OR refresh the page.Is there any method in client side or in server side.
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
I have to fire a method in my asp.net page. Condition is that this method has to fire when page is loaded in client's browser and client can see it. What I can do in server side and what I can do in client side ?
I have a page with simply a heading with logo image that is sensetive to click and redirects page to other page. in the middle page I have two text boxes to enter login information, whenever I push enter after filling each textbox it fires the event of logo and redirects to other page.

On Button click(postback), my dropdownlist of gridview is getting blank, so i m getting error of "Object Reference...." on the line "ddl.selecteditem.value"Also, dropdownlist's selectedindexchanged event is fired on Button Click(Page Postback), which is making the dropdownlist to go blank. AutoPostBack of dropdownlist is set as False,
So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event. The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.
I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
In our application we need to handle browser close event. When a user directly closes the browser, we should give him an alert message and stop him by directly closing the window based on some conditions. This we have handled through body onunload event. The problem is we are getting the alert message but after showing the alert message the window gets closed.
Is there any way to stop closing the window on click of browser close event?
And also when the page is refreshed, the last performed action is getting fired again.
public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) if (!IsPostBack) // If page loads for first time Session["update"] = Server.UrlEncode(System.DateTime.Now.ToString()); // Assign the Session["update"] with unique value [code]...

I have problem with user control: MyCollection : UserControl
MyCollection contains:
[code]....
Works fine unless I register event for some button:
button1.Click += ...
When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.
Button in this collection MyCollection has odd ClientID - itemsAddresses$button1
I have an implementation for my website to have facebook single sign on, using their javascript sdk.The javascript adds the cookie and I deal with it fine.The question is related to when an user logs out of facebook, I would expect the auth.sessionChange or auth.logout events to fire, but that only occurs when the page is refreshed.As my implementation is done server-side, this means that after the user logs out of facebook they can access one secure page one more time before being properly logged out.Is this the normal case or do these events usually fire up straight away and I'm maybe doing something incorrect in configuration of the facebook app?
I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
