Web Forms :: OnMenuItemClick Event Not Firing, Databindings Defined?
Mar 12, 2010
I've searched the forums and pretty much exhausted it on what I can find regarding the onmenuitemclick event not firing issue. The following is the code for my menu:
[Code]....
I've tried every combination of no url's defined in the sitemap, defining some of them, defining different databindings, all of which have not produce the result I want:I have 2 sitemapdatasources reading from the same sitemap. The only difference between the two is the starting node offset (which should have no effect on the rendering of the two menus). I want one menu to read only from the level 1 nodes of the sitemap and not postback (i.e., explicitly define the navigateurl field). I want my second menu to read only from the level 2 nodes of the sitemap and postback (i.e., not defining the navigateurl field). I have no problems getting the level1 nodes to redirect based on the urls. I can't seem to get SubMenu_MenuItemClick to fire. The page will postback, but the event isn't caught in the method.

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)

I've stepped through the code and verified this action. It gets to the end sub and just loops again. Also does it on the production server in IE and Chome (that's all I've tried). Here is the button definition on the actual ASP page:
[Code]....
It goes through the code, sends me an email, gets to End Sub, then loops right back to the top of the sub and goes through the whole thing again, sending me a duplicate email, then exiting normally and sending them to the About page. This is the only code in the aspx.vb besides the class def and inherits statement.

I have a two web forms with griviews that are bound to SQL through the same query in a class. Both have the same columns and footers. Both have a checkbox control in each grid row. The checkboxes on each form have OnCheckChanged event handlers that I put in the code behind. In fact, the html code is almost the same on both forms, and the OnCheckChanged code is exactly the same except for the fact that I have named them differently. AutoPostBack is true for both checkbox controls in the gridviews. One works, the other doesn't. The difference between the two is that the gridview row checkboxes that don't work are burried in a MultiView. Could that be why the codebehind event handler doesn't fire? Here is the html for the column:

Here is the html for the header of the gridview:

Here is the codebehind:

I have an asp.net 2.0 c# site.
In that site, I have a drop down list which allows the user to select from a number of forms with AutoPostBack set to true. I have a OnSelectedIndexChanged event on the dropdown which loads the correct control depending on which option is selected. See below:
[Code]....
Now, that works correctly and loads the form as expected, but the server side onclick event within each ascx control now doesn't work. Is there some problem with button events when controls are added this way? When I add the control in manually to the page it works fine.

i'm creating and adding checkbox in my code behind to a parent control.
autopost back is true, it's posting back on being checked, but i'm not sure how to capture the fact that it's checked before I recreate/add it to the parent control again.
i can search all controls and find it prior to re adding it to the parent, but it never shows checked...
i have a checkchanged event on it that never fires, thing it's a flow/view state issue, but not sure how to reslove...

I added some code to Global.asax on app start and I had to copy same project on a different machine and suddenly Global.asax file's event didn't fire. After doing lot of googling and trying many things I deleted the existing Global.asax and added a new one and then tested it. And I was surprised that it started to work again. so I would like to know what caused that previous Global.asax not to work?

I am losing User.Identity.Name unexpectedly, resulting in "out of the blue" redirects to Login.aspx.
This seems to happen randomly, often in the first few minutes after a user login.
To track this down I setup a Trace text file and append an entry to it when any page loads. I also write an entry from Session_OnStart event and Session_OnEnd event in Global.aspx. When user logs out, I call Session.Abandon, which should fire the Session_OnEnd event, and cause a log entry. However, this is not happening. It seems that Session.Abandon is not firing Session_OnEnd, inconsistent with info inhttp://msdn.microsoft.com/en-us/library/ms178583.aspx
Session_OnStart does seem to be firing as expected.

I am generating UserName based on FirstName.LastName after that I am hitting the database and checking if this username (Like AAA.BBB) exists or not if not then I am generating email address, if yes then it is thorowing error which is correct. And after this when I changed the username (Like AAA.BBBC) and hit enter or tab then again it should check the database and generate the email but it is not doing any thing means I think I am missing the cursor control or Second time TextBox_TextChanged event is not firing.

I have a user control that has an event that checks if a textbox is empty and does other processing...this event would also set a publ;ic property on the user control to a boolean value.
1) On the host page/parent, I want to click a button that will set off the event explained above.
2) Also, how do I reference the user control on the host page?

On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).
I here's the client-sdie code for the page (at least what pertains to this):

And here is the server-side:

I have a form that contains a Table control. The columns and rows are created dynamically, so there needs to be a way to maintain the state of the table. The table ALSO has textboxes within it that will fire a postback and update a database entry when the text has changed. Kind of like an excel-type configuration.
Anyways, I figured the best way to do this was to create a class object to create a standardized way of creating the Table, and then storing it in the Session. Every page reload I then readd the table to the form, so it looks like it is maintaining state.
Now, everything works fine and dandy, but my textboxes have an event handler which is stored in the class file. I can type in the textboxes and the form reposts, but the TextChanged event never fires.
Here's my code for the file:

And here is the page that utilizes it:

I'm using SelectedIndexChanged on a gridview row to trigger an event which is working fine in a normal webform. But, when I included "master page", it's not triggering the same event.
everything is same except, I added MasterPageFile location & removed FORM tag.
ASP code
<%@ page title="" language="C" masterpagefile="~/site.master codebehind="test.aspx.cs" inherits="Main.test" enableEventValidation="false"

I have a base user control (inherited from System.Web.UI.UserControl)
public delegate void MyEventHandler(object sender, MyEventArgs e);
public event MyEventHandler ControlLoaded;
//Fire the event from here
protected override void OnLoad(EventArgs e)
{
MyEventArgs cmdEventArgs = new MyEventArgs("somearg");
ControlLoaded(this, cmdEventArgs);
}
I have several controls that are derived from this base user control.
On the host ASPX page, I need to subscribe to the ControlLoaded event.
protected void Page_Load(object sender, EventArgs e)
{
//subscribe to the event
//This line DOES NOT WORK as I cannot attach event to a base control - It needs an instance of the user control which I don't have
BaseUserControl.ControlLoaded += new MyEventHandler(ControlLoaded);
}
private void ControlLoaded(object sender, MyEventArgs e)
{
// some control has been loaded
}
How do I subscribe to the ControlLoaded event?

Getting an unexpected event firing dropdownlist's selectedIndex event. When I try to redirect from another page by a linkButton. I just changing dropdownlist selectedIndex.Its okay.But after that When I attempt to redirect to another page,DropDownList's selectedIndex event firing (before linkButton Onclick event).But I am not changing any thing in dropdownlist.Somehow its event firing.
also any page viewstates is default (not off).But loading webcontrols into masterpage Page_Load like this :
[Code]....
if this dropdownlist selectedIndexchanged event firing. Because of I am loading webcontrols each masterpage's PageLoadEvent.
What do you prefer this may the reason of this unexpected event firing ? if so. Do you have a better technic to load controls Just for one time and not each pageLoad.maaybe a caching technic I am missing or shoult I use substution.
I couldnt find the main reason why a dropdownlist selectedIndexchanged event firing without I changed anything on that dropdownlist.
what reasons may cause this problem ? if you say viewstate its turned on defaultly. any other reason you know why ?

i am using VWD(visual web developer 2008) and DOTNET 3.5
i have a page on which i dynamically add multiple datalist controls on the oninit event of my page , on postabck i again add all these datalist controls to the page on oninit event
the template for all the datalist controls is defined using the ITemplate interface, the template defined for each datalist control contains a button which has a event handler attached to onclick event.
the problem is first time i click the button on postback i add the multiple datalist controls , the event gets fired which modifies the datatable i am using to generate my datalist controls and the datalist controls with the modified data show on the page but the second time a user clicks the button inside datalist the event does not get fired.
