Web Forms :: Rearrange Dynamically Visible Controls On A Page?
Sep 8, 2010
Here is what I am trying to do.I have a drop down list along with a 'Add' button (which are always visible). There are some other 'Label', 'TextBox', 'Button' in the page (which is not visible on load). Depending on the user selection from the first dropdown (and when click on 'Add' button), I would like to dynamically set some of the Controls visible.
For example (as per below code): When User selects 'Email' ... Label3, TextBox3 and Button3 will be visible. Again when user will click Button3, all controls will be invisible. I was able to Show and Hide those controls as per user selection and button click.
What I would like to do is, rearrange the controls. For example, If user selects 'Email' and click 'Add' button (Button5), It would display 'Label3', 'TextBox3', 'Button3'. Then if user selects 'Name' from the dropdown and click 'Add' button again, it would display 'Label1', 'TextBox1', 'Button1' below the Email controls. As of now it is apperaing on sequence as listed in html (Name controls always come first when visible, then 'Phone', then 'Email'). I would like to display the controls as sequesnce as user selects.
And next is when we will click the Button3 (which will hide the email controls), All other controls below email controls should rearrange and come up.
I hope I was able to explain what I want to do. There might be a very easy way (may be there is already a toolkit I don't know about).
The controls show up fine on the page, but they don't show up when I view source, nor can I access them from the code behind.If I add the controls in the on_init method, they work. But I have some business rules driving changes to the list of controls itself that require I fire the add method elsewhere. Has anyone seen this before? I'm away from work so I can't copy the exact code.
I have two terrible ideas for how to get it working. One involves some jQuery and a set of hidden controls holding a big array of integers; the other is run the method on_init AND on my other events so the controls at least show up. Both smell like ugly hacks.
I have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.
Dim DST As New DataSet DST = dataObject.RunSPReturnDataSet("uspUserProfile '" & Session("UserID").ToString & "'", "mytbl") 'Dim US As New DataSet [Code]....
I want program test for student exam. One Question with five answer. For example.

I have many question with answers. When I define correct answer. Program generation always correct answer. In this question correct answer letter C. I want every time program automatic change.
I have an Outer gridview (called grdvOUTERGRIDVIEW) and an Inner Gridview (called grdvOUTERGRIDVIEW) and I am able to see and use the outer gridview in my codep-behind vb page however when I try to handle an event for the Inner gridview then I get the warning: "handles clause requires a withevents variable defined in the containing type or one of its base types".
After creating the inner gridview I closed the page out and re-opened it however still getting that error and not able to create the grdvINNERGRIDVIEW.RowDataBound event function like I am trying to do.
I have set the Datasource of my gridview in code behind and created no columns (All columns in gridview are created automatically). Then I added a template column in gridview. Now I want to change the order of my Templated column in gridview at runtime. I want to show the templatedcolumn at column 20 but it is shown as first column. My Grdiview looks like this:
how can I set the template column at specified place(in my case it is column no. 20) and I've set Datasource and Databind the gridview in code behind at page load.
I have a datapager connected to ListView1, and after 10 records have been added to the ListView any further input of records gets added to the next page, but this now current page is not displayed, so how do I get it to change to the current changed page automatically ?
(with a gridview control you could just use this below:-)
How 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?
I have a masterpage (which we will call 'default'). This contains a second page (web user control) -'second'. And finally a third 'print' page. The 'print' page is also a web user control, however, it merely has a placeholder that contains the 'second' page.Is there a way I can add a control to the 'second' page - such as a literal, and only have it visible on the 'print' page?
Master pages wrap (with images) is not visible for some pages in the website. All pages in a members only folder are not inheriting the master page lay out. It looks like I need to specify the path somewhere due to the folder structure. What am I doing wrong? Thanks for your help. I have Images folder in the root, few pages that work as expected in the root and then couple pages in the Members only folder.Problem is with these members only webpages.
I have a loginview nested on a masterpage. Problem is that on local machine I see the loginviewy, but when I load it on server it does not show. Here is my masterpage html:
look at this sample link address: (weather.gov) [URL] if you view page source in browser, you can see that it shows data in XML format (usng xsl.?). I need to implement a simple web page like that. I think that web site uses XML XSL I'm going to implement a web application in asp.net which will use data stored in sql database (or xml database or web service) and show these information like other normal web sites but in xml format in nice UI (using xsl?).That Weather website is only a sample to show what i want to do (i will not use any data from that site, my application is different).My requirement is being able to view page source only in XML format.Now I'm clear that xsl is the solution for that, but considering to use this method in asp.net.(use xml/xsl in dynamic asp.net pages) My Question? It is important for me to make the web page output in xml format(visible in xml format in page view source) but looks user friendly for users. 1.how can i do it in asp.net ?
The code does not give any error. I can see it set the visible property to true/false. But actual control on page remain same (always visible on every page).
I've a page main.aspx. This page has a button 'Settings'. When it is clicked, I load another aspx page settigns.aspx in a popup. Now in the settings.aspx i allow the users to add controls dynamically. For example the user can create 5 textboxes. When he saves it there, I need to get that controls to main.aspx.
So i need to move all the controls from one page to another page. I'm not able to think of a solution with user controls.
