View 4 RepliesDynamically Make Visible Certain Panels?
Jan 11, 2010How do I capture other events in an asp.net textbox on a webpage in more of a way in which a windows app does? For example, if I want to handle when someone just presses a key (keydown) on a textbox in a webpage?
The functionality that we want to create breaks down like this:
We want to create a "smart" search box at the top of our page. When the user starts typing, a little panel or some element should become visible and it will have some check boxes on it. They can search for one or many different types of searches: First Name, Last Name, Business Name, ZIP, Customer Number, and Contact Info. As they begin typing their search, we need it to execute some code that attempts to figure out exactly what they are searching. So if it can tell they are typing in alphabetic characters and not numbers, then we know to NOT check the Customer Number box, but we will want to check the First Name, Last Name, and Business Name boxes. If they start typing a number, we know that we can check the Customer Number box and leave the First Name and Last Name, etc boxes unchecked. If they type a number that is 5 digits, then we know to check the ZIP and Customer Numbers both. Any other length number characters and the ZIP will be unchecked. And any other rules like these that we might want to implement in the future. The idea here is we will almost always be able to tell what someone is searching, but the user can always check any box that they want to search for if they so choose. For example, if a business is named "123 Plumbing Company" and they just want to search the Business Name field for a number, they can over ride it and do that. Otherwise, they just can blindly type their search and hit enter and the program will usually know what kind of search they are trying to do.
I come from a strong windows app development background and have just recently tried to do some web development professionally. A quick few sentences on what philosophy I am missing out on as far as a more robust and "Windows App-like" webpage would be appreciated if anyone wants to coach me on that area and point me in the right direction!
Also, in my example we are using master pages. So if you can imagine a typical master page that has a logo top left and a search box and button top right, then you can picture what we have. Its simple looking. But with the content page being a separate aspx page, we are having trouble referencing it after a search is performed anyway. So what I mean by all this is The masterpage.master has a search textbox. They type something, hit enter. We then want a gridview that is on our default.aspx page to update with the results of the event that was fired from the masterpage.master.
My windows app background tells me to just point to it like I would from two different forms. Like if I had a form1 with a search box on it and I wanted it to show up the results on form2, I would just say Form2.Show: Form2.GridView = whatever.
Of course, with my confusion of what the scope of these asp.net pages is, I am having a difficult time just visualizing everything and how they are inter-related.
So I guess to recap here:
1) How do I tap into more events with textboxes or any other asp.net control. Is the answer AJAX? If so, can you elaborate just a little bit?
2) How would I use the keypress or keydown type of event to make a panel or some kind of content holder to become visible when the textbox gets focus from the cursor and go back to being invisible if it loses focus.
3) What about the scope in which asp.net pages behave?

Handle Button Click Event From User Control Loaded Dynamically
Jul 31, 2010I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.
I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?
Child code:

If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().

View 3 RepliesState Management :: How To Make An Image Control (dynamically Added To A GridView Column In It's RowDataBound Event)
Mar 28, 2010I have a gridview that on it's RowDataBound event I dynamically add Image Controls to some columns.
The problem is that I lose these images on the next PostBack.
OBS: The GridView's EnableViewState propertie is already set to true
I know about the page lifecycle, but how can I persist these images if I have to add them on the RowDataBound event?
In addittion, if I add a static TemplateColumn with an Image Control and I set it's ImageUrl propertie inside the RowDataBound event it will obviously persist between postbacks. The problem is that I don't know how many columns with images I'll have, it's defined on the datasource.

Web Forms :: Load A User Control On Link Click Event Of A Link Button During Postback Of Aspx Page?
Mar 2, 2011Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.

View 4 RepliesC# - Button Event Handlers Do Not Fire On The First Click But On The Second Click After A PostBack
May 4, 2010Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

Force JQuery Click Event To Proceed Any Control Click Event On Page?

View 1 RepliesWeb Forms :: Hide Divs On The Initial Load And Make Them Appear On A Postback Event?
Dec 1, 2010I have several divs on an asp page. All of my divs are runat="server". On the initial load of my page I set all the divs visible property to false because I dont want them to appear on the first show. Then, I have a drop down list raising postback events.
On the selected index changed event I am setting the visible property of my divs to true to make them appear on the page. However this does not work.
I discovered that, on the initial load non of my divs are added to the page's html content. So, on a postback event non existing divs can not be made to appear. If all the divs would set to visible = true on the initial load, postback event would work just expected.
Could any one tell me a way to hide divs on the initial load and make them appear on a postback event?

Web Forms :: No LinkButton Or Button Click Event Fires (no Postback)
Mar 24, 2010I dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
View 5 RepliesWeb Forms :: Button Onclick Event Only Triggers Postback On The First Click?
Nov 11, 2010I have created a user control which has a form and 2 buttons; Save and Submit. Both buttons are created at design time. Users can enter details in the form (e.g. title and description of an item) and click Save which does some server-side processing to create an 'Item' then clears the form.
The buttons:
[Code]....
[Code]....
And a placeholder to add dynamically created controls:
[Code]....
I am saving the Items in ViewState and dynamically creating a LinkButton control for each Item which allows the user to edit the item:
[Code]....
[Code]....
Now, when I test this in Visual Studio 2010, it works fine;
1. Enter Item title and description in form
2. Click Save
3. Save button triggers postback and onClick event code is run
4. ViewState list is displayed below the form
When I create a local IIS web site for testing, the postback on the Save button only works the first time I click it. Postback is false on the second click and the page reloads without running the onClick event code.
