C# - Accessing Labels In Another Webcontrol On The Same Page?
Aug 17, 2010
I'm using one Sublayout (Sitecore) and have a placeHolder that currently holds 2 webcontrols. I want to access the Label from one Webcontrol to the other Webcontrol.Do i have to find the Label recursively or can i just access the Label on another way? I tried different methods like:
I am trying to access a webcontrol (a Textbox) from the EditItemTemplate of a DataList, so I can change it. When I try to do DataList.FindControl("TextboxID") it comes back with null because it doesn't recognize the textbox has rendered. I've tried looking in the DataBinding, DataBound events and those don't work either.
To be more specific, I need to change the value of a textbox when the user uses a Calendar control, so I need to access the control from EditItemTemplate in the Calendar_SelectionChanged event.
I have a page with a datalist on it, with an image button and some labels in the datalist item(1,2)..
I have some more labels on the page which get their values from querystrings(17,18)..
I have more labels which are empty (34,35)
On image click in the datalist item, i want the labels from that item to add with the labels outside of the datalist, and the last lot of labels to show this number..
I have a normal Wizard WebControl. On the first page of the Wizard, in the StartNavigationTemplate, I've added a button. When clicked, the button will generate a PDF (using iTextSharp) and post it back through Response.OutputStream. All this works just fine.
Now I want to wrap my Wizard in an AJAX UpdatePanel, to make it switch through the steps smoothly. However, this means that the Response from my PDF button is intercepted and does not do a post back. My solution to this was to add a PostBackTrigger for the PDF button, but since the button is in a template I ended up adding it dynamically. Here is how my final code looks like:
[Code]....
[Code]....
- if I load the page and the first thing I do is to click on the PDF button, then the PDF file is returned as a normal post back
- if I load the page, navigate to step 2, return to step 1 and then click on the PDF file, then the Response is intercepted by the UpdatePanel and not displayed.
<MyUserControl id="myusercontrol" runat="server" MyUrlProperty="http://myurl.com/" /> which can't be casted from System.String to System.Uri EDIT The control is a sealed class and I don't want to modify it or write an own control. The goal is to set the url-property which is of the type System.Uri and not System.String.
I have some labels on my Page (e.g. Label1...Label100).
I don't want to loop through all Labels to check if Text property is = "" (or string.Empty, whatever), so this's my question - is it possible to use LINQ or Lambda Expression to get all "empty" labels ?
What I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page.
And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image.
So how can I make these labels stick to the Panel and not the Page? How do I do it?
how can i access the labels from a list view when i submit the page? for example i have a ListView with 5 items and each item contains a label calles Label1 and i want to read out each of this labels when i push the submit button
I have a form with a combination of dropdownlists and textboxes that I want to be able to show a user as a summary in another page before submitting to a sql server. Page 1 will have a verify button which will then pass the dropdown and text box info to page 2 where end users will be able to either submit the page or cancel the action. What's the best way to pass the values from page 1 to page 2?
we are able to export GridView, Chart, Panel to PDF but by doing this we can only export 1 control. We ahve requirement of having multiple chart controls on one page (like Report dashboard) with some data in gridview etc. How can we export full page to PDF?
I am using Master page and Content page combination.But how can i access <body> tag and it's event (onload, onunload) of Master page in .aspx page that is not a content page.
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
I have a problem i am trying to work out the best method with my limited skills. Im using vb.net(VS 2010) I am using a dll for an IFrame , which is call from code behind. On my site I havea masterpage which has two gridviews. ( GrdViewWebBureau is the one i am using for this query) GrdViewWebBureau is contained within an update panel and updated on a timer control trigger. GrdViewWebBureau updates the page with file counts and status from our clients. I can click on any one of the cells and the code behind is fired. What I am trying to do is put an IFrame on the master page and every time a user clicks on the grid, the Iframe is fired up.
I have tested the iframe and vb code behind from a dummy page and it works, however when the Iframe is on the master page it doeant work. What I am tryingh to achieve is that no matter what page a user is on the site, they will be able to click on the GrdViewWebBureau and the iframe will fire with the correct childpage. Each webPage may also have an Iframe as well, so i dont know if it is possible to make the IFrame global and just call that control ?? I have no idea if 1 this is possible with the code i have and 2, if i have the brains to understand the who what why and when.
I have a master page that contains the main site navigation and a child master page that contains a secondary menu. I want to set the starting node on the secondary menu based on the selection on the main menu.
I can get the code to work when the menus are on the same page, but when I separate them into their respective master pages, I get an error saying "The name 'SiteMapDataSource2' does not exist in the current context".
I have tried playing around with the FindControl() method, but either it won't work or I'm not getting the syntax right. Most of the information I find is for a child page referencing the master page, but not the other way around.
How can I access the SiteMapDataSource2 control from the master page? If possible, can you include the exact syntax as I am still trying to get the hang of this.
Here is a basic representation of my code, with all of the uncessary stuff stripped out:
I have a custom basepage and a master page in my web application. In my master page, there are events that I run from each page in my web application. Instead of putting the code in each of my pages, I decided to create a base page that each web page will inherit from. Trouble is, I cannot get the base page to invoke the events on the master page.
I'm using the DataList WebControl for the first time. What I am wanting to do is dynamically load a datalist bound to a datasource with radiobuttons. This datalist control resides within a <div>. In design mode, everything looks great, however, when I run my web app...nothing appears. Do I need to associate the datalist control to the div by chance?
I have a WebControl that I'm creating and when I'm in the designer...you really can't tell what it is...see Attachment 1 below. See Attachment 2 for what it looks like rendered in the Browser (IE & Firefox). What would cause this. I really can't even throw controls onto the UC looking like this. I have to go into the markup and do the drag and dropping.
I have a ListView control in Asp.Net WebForms which display a set of elements, I have at the end a "More" button like Facebook for example. During the postback I want to get from database another 10 elements (I have already displayed 10 and I don't want to retrieve them again)
Something like this.
foreach (var item in New10Items) ListView.Items.Add(index,DataItem)
the problem is with DataItem, how to Bind it before add it? what is the best way of solving this?
1st) Server retrieve an image from Database, in the Database i've only the path, then i encapsulate the image in a XML and i send this XML to the client.
2nd) The client decapsulation the img, so the client has an array of bits with the image. it's not allow send the path for security.
Now i need associate this image with my webcontrol img.
i do something like
ImgUrl = "Handler.ashx?num_doc=13"
and it works, but really i need do something like:
ImgUrl = "Handler.ashx?num_doc=" + num_doc;
where num_doc it's a http parameter recieved from a page. I'll try to put the ImgUrl from code but it doesnt work, just show a path.
