Web Forms :: Master.FindControl Removes UserControl?
May 19, 2010
I face this weird problem when I was trying to add multilanguage support to my website.The main login page contains user control and I am also using Master page. I added a linkbutton to master page so I can switch to other language from any page. So, whenever I want to switch langauage, I check this linkbutton text value. so I use this code
I have a UserControl that has some controls inside. I want to refer those controls after, in another postback. But when I try to get them the Controls property of my controls returns null. I'm working on vs2008.
So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.
MasterPage.aspx
[Code]....
MasterPage.cs
protected void goToSelectedPage(object sender, System.EventArgs e) { temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1; ct.ID = "TestMe"; this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ct); } //This is where I CANNOT SEEM TO FIND THE CONTROL //////////////////////////////////////// protected void lnkSave_Click(object sender, System.EventArgs e) { UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel; Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control; temp1 test3 = test2.FindControl("TestMe") as temp1; string maybe = test3.Col1TopTitle; }
Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs
how to refresh particular usercontrol in the master page?after clicking some event on particular usercontrol i just need particular section on the page to be refresh instead on whole master page.explain me now to work in ajax to do reflesh as i am new in ajax i would be thankfull if explain me in detail.
I tried to do some think like following in usercontrol page but doesn't work.
i have one method in master page and a label in same master page, and their is one method which changes text in label, and i want to call the same method in Master page from my Usercontrol.
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes
when I have <form> </form> tag on my .aspx page. then it cause some problem in page, for instance: I have header, which has one vertical line in it, but when I use form tage in page then all data is correct, but from the header it remove one verticle line.page with form tag in local environment (development environment) works fine, but when I move it to live then it creats problme.
im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
There are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
I have an AJAX NumericUpDown Control that takes a decimal. If I put in 1.30, it removes the zero. I do not want to remove the zero, it must remain at 1.30.
A demo of this can be found here: [URL]
For example, enter 1.30 in the text box then tab out or click somewhere else. The zero is removed.
I have an ASHX handler or an ASPX page (the problem happens in both cases).
The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.
The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)
I have some weird problem. We're using Windows Server 2008 R2 x64 (8 Cores and 8 GB RAM) with IIS 7.5 and ASP.NET MVC 2.
I always cache (simple) stuff via the context cache and it seems like 9 out of 10 immediate page refreshs the Cache["MyKey"] is always null, even though there's no memory limit set on the pool and the server has lots of free memory.
I add expiring data via:
[Code]....
When just doing: Cache.Insert("MyKey", myObject); or Cache["MyKey"] = myObject; I get the same result (cache is almost always null for that key).
As you can see I added a callback, which writes the CacheItemRemovedReason to a text file, and the text file says CacheItemRemovedReason.Removed for MyKey. The doc for CacheItemRemovedReason.Removed says, that I call Remove/Insert on it, even though in my whole project there's no "Remove"-calls, just simple if(Cache["MyKey"] == null) {Cache["MyKey"] = ...} stuff.
I have a ShoppingCart UserControl on MasterPage. I have a following functionality: User adds item to the cart. after clicking the button "Complete Sale" in UserControl the page is redirected to "CustomerInfo.aspx" and after filling the Customer information and clicking on submit which is on CustomerInfo.aspx page i want to call the "Complete Sale" click event of UserControl from "Customerinfo.aspx" page.
Here I have gridview control with checkbox for selection of one or two records. Have one button and when clicking this , i need to get the selected records values and assign this values to the textbox which is in usercontrol1.
I haven't been able to find relevant information through searches. I'm very green when it comes to sever side scripting. I have an ASPX page with a standard form. In the head I have meta tags, the title tag, and a link tag neatly ordered on their own lines. However, when viewing the source code after publishing to the server, the spacing between the tags is removed and it looks quite messy. (There are also <style> and <script> tags that follow, but they remain unaffected.)
I realize this has no practical effect on the site itself (in an SEO sense or otherwise). My project manager shows the source code to our clients to educate them on meta tags and page titles. It would help if it wouldn't become jumbled like this. I wonder if this is a common issue and if it's possible to prevent through better coding practices. HTML as authored, with tags separated on their own lines:
HTML Code:
<head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." /> <meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" /> <title>Lawn Care Waukesha — Cut My Lawn, Lawn Care Service</title> <link rel="shortcut icon" type="image/x-icon" href="favicon.ico" /> HTML after being processed by the sever, with all the tags running together:
HTML Code: <head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002!

I'm not sure it's relevant, but here's the script used to send the form (which I didn't write, by the way). It's the final tag inside the page head:
HTML Code: <script type="" runat="server"> Protected Sub SubmitForm_Click(ByVal sender As Object, ByVal e As System.EventArgs) If Not Page.IsValid Then Exit Sub Dim SendResultsTo As String = "email" Dim smtpMailServer As String = "smtp" Dim smtpUsername As String = "email" Dim MailSubject As String = "subject" Try Dim txtQ As TextBox = Me.FormContent.FindControl("TextBoxQ") If txtQ IsNot Nothing Then Dim ans As String = ViewState("hf1") If ans.ToLower <> txtQ.Text.ToLower Or ans.ToUpper <> txtQ.Text.ToUpper Then Me.CutMyLawnForm.ActiveViewIndex = 3.......................
How to make a build in VS 2010 within an ASP.NET MVC application that would remove all of the source code (CS and VB) files? When I build a website or web app I usually copy the contents of the entire solution to the hosting server. Mostly clients get the source but sometimes I do not want to expose the source to the hosting server thus only the Public (or Content) folder, views, masters and the built DLL should be copied.
Manual solutions are not applicable. What do you guys use?
What I'm interested in is a regular expression that will accept HTML input and remove all attributes inside the tag while leaving the tag intact. For example I want this...
<p class="test" id="TestParagraph">This is some test text right here.</p>
EmptyDataTemplate and EmptyDataText not working in GridView
using CSS-Friendly Control Adapters removes the data that would would be populated by EmptyDataTemplate or specified in EmptyDataText in GridView. One of the solutions is to disable the addapters for GridView components as specified in this answer Is there a solution, that would allow to keep the use of CSS-Friendly Control Adapters for GridView and still take advantage of EmptyDataTemplate functionality?
I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument() doc.Load(Server.MapPath("Template.htm")) Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title") title.InnerHtml = title.InnerHtml & "CEU Classes" Dim topContent As HtmlAgilityPack.HtmlNode = doc.GetElementbyId("topContent") topContent.InnerHtml = html.ToString doc.OptionWriteEmptyNodes = True doc.Save(outputFileName, Encoding.UTF8)
More info:
It was removing my closing image tags, after I added doc.OptionWriteEmptyNodes = True, it quite doing that.
I have an updatepanel in my content page with a timer which re-renders the updatepanel every 5 seconds.I also have a textbox outside of this updatepanel in my masterpage.Whenever the timer ticks, focus is lost from my textbox. What possible reasons are there for this happening?
