I pass a string value (1,2,3,etc) via public method called "DataTypeId". The problem is that all the events in the control are fired first so dataTypeId is always null:
[Code]....
I am sure there are many ways to achieve my goal but since I am a beginner I dont know what they are. All I am trying to do is to have a user control TextBox which will work with a Listbox in a host page. The listbox will pass the data(1 - String; 2 - Xml) and so on. Then I change the regular expression in the user control and return that to the form. If there is an easier way to do that or a sample control out there which achieves the same goal.
Why is it that the aspx.net system fires all the TextChanged event (for a slider) to a value of 0, when you did not originally set any values?
What I notice happening is, if you do not declare a Slider1.Text = "0" value initially, then when the page_load fires, the control protected void Slider1_TextChanged is fired automatically.
I want to raise an checkbox check-changed event but its not firing :( . It Dosent raise even an command event.

I am creating web site that reads Excel file. For certain excel files the events are not getting fired instead a PAge not found message is displayed while for some files the events are getting fired.
I have a browse btton user brwses the files and click on button. But the click event is not getting fired
I have an update panel in my ASP.NET web form with a trigger that will fire a click event when the contents within my update panel is updated (it's a grid view with fields). The event that is fired when then take the changes user made and do some calculation and then update another update panel with that information. This is all fine and dandy when the user tabs along the form and fill out the form in a orderly fashion before hitting any buttons on the page.
If a user accidentally hits another button on the page while changing the content in my grid within the update panel, for example, the user enter a value in my grid view control, without tabbing, the user click the save button. Logically, i believe that the trigger should fire the click event first (event A), and then the save button event (event B). But, consistently I haven't seen event A gets fire correctly while event B gets fire all the time. is there a way to ensure event A always gets fired before event B? also if event A update another update panel without the page will event B fire after the update is complete?
I have recently published my website, it worked fine but the only issue is that the error handling code in the global.asax never works. It works when I tested the website on my localhost but not when it is deployed onto my hosting provider.
I tried moving my global.asax file onto my root directory (not the bin) on the hosting folder, then my whole website wouldn't even start. I get the error message "System.Web.HttpException: This server variable cannot be modified during request execution."
But if I remove the global.asax, then it is running fine again.
Note: I didn't use the publish function in Visual Studio to publish my website, I sent the files over one by one via cPanel. Note: I googled about this, a lot of them are saying about global.asax being precompiled into a dll, but I can't find that dll in my local computer.
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.
I have created some dynamic controls, at the runtime from server-side and I want to write the event-handler for those controls. All I did is :
// Defined the control as
[Code]....
// And I wrote the even handler as :
Private Sub addobjective(ByVal sender As Object, ByVal e As System.EventArgs) End Sub
My problem is the event-handler function addobjective() is never being called and not getting fired, So the program is not doing what it is supposed to do at the click event of the server side commandbutton add.
a problem with firing click event when asp:button control is click on IE8. Its properly postedback but when i click button in IE8, it does'nt do any thing. After review on mouseover on button the the following type link showing on button pagename.aspx?vid=18 on next click it incremented pagename.aspx?vid=18&vid=18 and so on. How can i fix button problem in IE8.
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.
I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a gridview that includes dynamically created dropdownlist. When changing the dropdown values and doing a mass update on the grid (btnUpdate.click), I have to create the controls in the page init so they will be available to the viewstate. However, I have several other buttons that also cause a postback and I don't want to create the controls in the page init, but rather later in the button click events.
How can I tell which control fired the postback while in page_init? __EVENTTARGET = "" and request.params("btnUpdate") is nothing
I've added AddHandler to dynamic controls in code behind but when I (for example) select an item from the ajax combobox (selectedIndedChanged) nothing happens.
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
