VS 2010 - Adding Linkbuttons To A Page Dynamically On Page Load
Jun 1, 2012
Ok, so I'm adding linkbuttons to a page dynamically on page_load.I had it to where the link buttons were redirecting to a page with a query string attached. I was attempting to use the AjaxToolKit's AjaxFileUploader and ran into issues with existing query strings.
So what I'm trying to do now is handle the click event of the linkbutton server side, set 2 session variables and then redirect the page to the same page, but with out appending a querystring so the ajaxfileuploader will work correctly.Here is my linkbutton code:
vb Code:
Dim Lin As New LinkButton         Â
Lin.Text = dr("DeptDesc").ToString         Â
Lin.CssClass = "deptlink"Â Â Â Â Â Â Â Â Â Â
Lin.ToolTip = CDate(dr("MeetingDate").ToString).ToFileTime.ToString         Â
'Lin.OnClientClick         Â
[code]....
I know I have Lin.PostBackURL and Lin.setAttribute(...). It didn't work with just setAttribute and I saw a post online about someone setting the PostBackURL and it working...
I have read in so many articles that all controls get their values from viewstate before load event. Then how my dynamically added controls get their values when i am adding them in OnLoad event ie after LoadPostData event.
I have the following code which adds a label and a gridview to an asp.net page:
GridView grd = CreateGridView(kvp.Key.Text); Label l = new Label(); l.Text = "some text"; l.CssClass = "this has no effect"; placeHolderResults.Controls.Add(l); placeHolderResults.Controls.Add(grd);
Two questions really:As the page will have a multiple and unknow quantity of Label + Grid pairs I'm looping through the above code, is this the best way to add the controls to the page?I cannot style the label? How do you do it? Looking at the HTML which is created, the label turns out to be a SPAN.
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?
I have a very strange problem with my website... I created a rather large page, consisting of a few tables with some labels and textboxes where the user can enter a mechanical car setup (it's for a racing game).
I was working with simple textboxes previously, but I recently switched over to a NumericBox control which should allow only numeric input using some client-side javascript. The NumericBox control is simply a UserControl with a single TextBox on it, and some client side events are added to this textbox which call methods from a single javascript file ("Scripts/numericValidator.js")
When I put a couple of these boxes on a page it works just fine, I can only enter numbers. For it to work though I need to add the script to the page and I do that using this line, either in the head content or in the body content controls:
(the path is chosen with the 'Pick URL' dialog so it should be alright, and it does indeed need to go up two directories first as the page is in the '~/Pages/RequireLogon" directory) However, after replacing most of the textboxes on my large page with NumericBoxes, and adding this script line to my aspx code, the design view is 'broken'. I cannot see any of my controls anymore, and I cannot even put any new controls on there. It seems like the Content control is missing, even though it's still there just fine without errors in the aspx code.
When I remove the script line, the problem is fixed again, the controls re-appear. So it's definitely the script line causing the problem, but I cannot see how it could...I tried it with a new blank page and the problem appears there too. If I use this simple page with just a button:
Basically I have images details which are stored in a database and would need to dynamically added hence, why i need to write within a div container. Any ideas how I could achieve this?
I am using jquery ajax method to get data from a web method and present data using DOM(similar to that of google search results).B'coz the data returned from the web method is huge I want to paginate the results.For that I need to create buttons corresponding to the page numbers based on the no. of records the web method retrieves from the database.So I have taken a div on the page.In the web method ,as soon as I can find the number of records obtained from the database,I want to create the buttons and add to this div and display 10 records per page.As far as I know, it is not possible to access anything that is placed on the asp.net page from Web method.In that case how do I paginate the results?
My C# web app requires the user to enter automobile information. The user can add information for one auto, or more (max 20).
My page has these text fields: Car Number, Car Make, Car Year, Mileage, VIN I have a button that allows the user to "Add More Cars" is to allow the user to add more than one car.
When the user clicks "Add More Cars", how can I dynamically display the text boxes, and keep track of how many cars the user has added (in order to load them to an array and write to database)
I have a set of links that exist in the master page. I have a css class i would like to assign to a particular one of them depending on if that is the page you are at during page load. ex: Home will have the current_page_item class if you are at the index page
This is what I have:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load DirectCast(Me.Master.FindControl("ctl00_homeLi"), HtmlGenericControl).Attributes.Add("class", "'current_page_item'") End Sub
I have a webpage that I'd like to display a different shortcut icon depending on whatever the status is of the app. I have the page pin'd in Firefox so I can always see the icon. How to accomplish this?
I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?
need to open an aspx page (called editItem.aspx in code below) loaded dynamically inside a jQuery UI dialog from a parent aspx page. the child page has a button server control and should go back to parent page after postback. with the following code I get the error"The state information is invalid for this page and might be corrupted"
I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.
I am trying to dynamically add a queryextender expression to the page. something like, when the user clicks a button, we need to add a OrderbyExpression. The following is the code used. It works when added in Page_Load but doesn't when added on a button click event. Upon button click the page just reloads and ignores the filter condition.
I am using VS2010, .Net 4. I am trying to add a ScriptManager to my page, so I can reference an AJAX Enabled WCF Service. When I add the ScriptManager control to my page and view it - I get the error shown below. I have no clue how to resolve it. I get the error by simply putting the control on my page (not reference the WCF Service).
(script type="text/javascript") //(![CDATA[ if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.'); //]]) (/script)
Actually, my problem is that I am not able to access the service. I am referencing it inside the ScriptManager and have the javascript code in place, but Firefox is reporting that it cannot find it. Says it is not defined. I do not know how to test this or determine where it is failing.
In this repeater linkbuttons are generetaed with an onclick event.This onclick event sets a multiview to the corresponding view.The multiview is in an update panel as well.When a linkbutton in the repeater is clicked the corresponding view is shown, but a complete refresh of the page is done.How can this be prevented, because when I have just linkbuttons on the page (so not in a repeater) that set the multiview to the corresponding view, only the multiview is refreshed instead of the complete page
I am working on an app where i am having some linkbuttons in master page. I want to display them depending upon the authorization given to them once they logs in. I have initially made all of them visible false and then i am checking the authorisation in the aspx.cs class of master page. I make the link button visible depending upon the right granted to the user. But it is making all the link buttons visible. Instead it should only make two of them visible and rest should be hidden. Following is my code from MasterPage.aspx.cs:
