I am using a asp.net website and using vb to query my sql database although i need to use check boxes but have no clue how to code them in vb, any example i want to use 4 checkboxes to show the information of which ever is picked.
I am trying to use a check box within a repeater in an asp.net vb application. Basically, i am have an application that allows users to create blog posts and then other users can comment on them. I am using a check box to provide the user with functionality to like the posts comments.
When the user clicks on like, it is supposed to fire the event which will insert or update the users like record. However, this even does not seem to be firing.
I set up the check box within a table within the repeater as follows:
Code: Protected Sub chkLikeComment_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) MsgBox("like clicked") Dim CommentItem As RepeaterItem = sender.NamingContainer Dim HiddenID As HiddenField = CType(CommentItem.FindControl("HiddenCommentID"), HiddenField) Dim CommentID As Integer = Convert.ToInt32(HiddenID.Value)
[Code] ....
I included a Msgbox in the event to see if i would at least get that and then the problem might be something else, but i don't even get the msgbox to pop up which is why i'm thinking the check changed event is not even firing.
I've been searching the net for solutions on how to get it to fire, but what i've found so far either does not work or i am not using it properly. I saw something about re-subscribing to the event in repeater's on item data bound, and tried to set up that the way they had, but i am not sure if i did it right, as i get an error that says the checked changed cannot be called directly and to use raise event instead...
Code: Protected Sub rptComments_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptComments.ItemDataBound Dim CheckLike As CheckBox = CType(e.Item.FindControl("chkLikeComment"), CheckBox) CheckLike.AutoPostBack = True CheckLike.CheckedChanged += New EventHandler(chkLikeComment_CheckedChanged) End Sub
I have been trying to get this to work for about a week now with no luck
I got a gridview in place after nutting it out (new to Asp.net WebForms) after asking here. Remember my gridview are being bound to an IList<>. Works fine (code below)
I want to add a checkbox next to each row so users can select those records that they want (not relevant..yet)
However I could not find a way to set the id of the checkbox to the Id of the instance of my class (IList<MyClass> for instance where MyClass got an EntryId member).
This is what I got so far (working fine..just that id's)
Another question (related, so figured I'd ask here) is how do I get the checked items in my code behind (got a link button and want to go over the selected items in it's click event).
I have a page that im using javascript to do a select all / unselect all for my checkboxes on the page. Now i need to determine in the code behind if all of them are checked, im wondering if it would be easier to just set a session or something whenthe select all is checked, but that wouldnt be accurate, because after you select all, you still can uncheck some..
So i need it to check at the time the button is clicked.. there are currectly 30 checkboxes, NOT a checkboxlist.
I tried using the site search but getting an error has occured when i click to search..
I have a gridview which has bound fields and a template field for checkbox.I wrote a code for deletion of records as per checking checkboxes.My problem is
HtmlInputCheckBox chk; foreach(GridViewRow dr in dgvdetails.Rows) { chk = (HtmlInputCheckBox)dr.FindControl("ch"); [code]...
I'm trying to create checkboxes inside Listview from code behind, but I'm having problem creating them.
What am I missing here?
Checkbox's ID comes from Datareader.
Here is my code.
If reader2.HasRows Then While reader2.Read Dim jobid As String = Convert.ToString(reader2("JobTicketID")) Dim jobtitle As String = Convert.ToString(reader2("JobNickName")) Dim item As ListViewDataItem For Each item In ListView1.Items Dim jobtd As HtmlTableCell = CType(item.FindControl("jobtd"), HtmlTableCell) Dim jobtr As HtmlTableRow = CType(item.FindControl("jobtr"), HtmlTableRow) Dim cb2 As CheckBox = New CheckBox cb2.ID = jobid + "cb2" cb2.Text = jobid + IIf(jobtitle <> "", " (" + jobtitle + ")", "") jobtd.Controls.Add(cb2) jobtr.Visible = True Next End While End If
I´m developing a database driven asp.net 4.0 application and are currently stuck with the following issue.
I need to dynamically add checkboxes using code behind. These checkboxes represent activities that the user may chose from by ticking the ones that they are interested in. I do not know the number or which activities that should be presented until runtime so hard coding checkboxes is not an option.
On the client side I need to keep track of which checkboxes/activities the user have chosen as I need to calculate the cost for these without doing a postback. I would like to use javascript to find out what activities that are chosen and also calculate the total cost using javascript.
To implement this I tried to use Page.ClientScript.RegisterExpandoAttribute (server side) and javascript (client side, but I do not manage as ticking any of the checkboxes will not fire a client side event. I´m also using Telerik RadPanelBar controler.
I´ve been stuck with this for some time now and have a nice deadline coming up :) I would be most thankfull if anyone could point me in the correct direction as I feel a bit clueless. Perhaps there is a much easier way of solving this? Perhaps my code is all wrong?
i want to paste some code behind a button so as to cause the execution of a query specified by a sqldatasource.the sql datatable is made within the project in visualstudio 2010.
How I get the left and top of a div control in code behind. The reason being is I have a div with a background image and I drag some images on to it. On clicking on the save button I want to save the position of the image relative to the div so I can load the image next time and place it on the same location as before.
I have recently been dropped into the ocean known as ASP.NET. Here are my questions:
1.) I am trying to deploy my code to a server. I read there are a few different ways to do this but I will stick with the simple way for now. The way I am deploying is to remote into the server and copy my files(with a copy paste) and placing them on the server. My question is do I put the files on the server in the virtual directory or on the real directory that it points to?
2.) When I deploy my files are the changes recognized automatically or do I need to issue a command to IIS?
I've had this problem for a while now, it seems to come and go (sometimes it happens, sometimes it doesn't) and I can't really figure out what's wrong.Basically my aspx code will sometimes format automatically, except not in the way I want it to. I always structure html and xml-like code as such:
This way I can quickly see which tags belong to which, and I think this is the usual way html is formatted, right? Anyway, suppose that I have this code in my aspx code window (don't mind that it's not aspx code, that's not the point), then sometimes VS will automatically format it to this:
Basically it seems to put all closing tags on the last line, leaving me sometimes (with many nested tags) with an extremely long line at the end, making it completely impossible to see the structure of my code. Here is an actual example. This is how I wrote my code:
I have a few pages in my web application where I would like to be able to use the code-behind of a master file, but not 'inherit' any of the other stuff like asp/html markup etc.
I am using a web application project in visual web developer express 2010 on Windows 7 x64 targeting .net 4.0. I've linq to sql quite a bit with visual studio 2008 and it worked with no issues. I added a dbml file to the root of my web site and dragged over my data model. When I run my project, I get the following error:
Type 'DataClasses1DataContext' is not defined. The line of code it is having a problem on is Dim db As DataClasses1DataContext = New DataClasses1DataContext()
However, intellisense is recognizing dataclasses1datacontext as a valid class. If I view the code on the dbml file, it has essentially an empty class definition. It appears it didn't actually generate any code relating to my data model. I tried adding system.data.linq, etc to my web.config file but it didn't make a difference. I always get the error above. Again, I'm using a web application project which appears to function a little differnetly than a web site project. Any ideas why I can't get this basic functionality that was working in 2008 to work in 2010?
As part of our branding of Sharepoint 2010, we'll be modifying some custom HTML menu's based on database and user permissions.
To do this, we are looking at the use of code-behind in a custom Sharepoint 2010 master page.
The only reference I can find to creating a code-behind file for sharepoint 2010 is this blog post series. The issue I have with this is that it's using the Visual Studio 2010 Sharepoint integration, which has the genius feature of requiring a local instance of an entire Sharepoint site. This isn't something that I can do/get.
This is the MSDN for code-behind master pages in Sharepoint 2007. I'm assuming it's similar but I can't find anywhere that describes it as such.
Is deploying a code-behind for a custom master page the same as in Sharepoint 2007 or does anyone have any experience doing this?
I'm trying to do the equivalent of a "Are you sure you wish to delete?" and then if yes, return to a function in the aspx.vb code. Here is what I have:
And then on the form, the btnCancel does popup the menu, with Yes / No and the text "Are you Sure?"But, even though I have a button called "btnCancelYes", I cannot get the code in there to trigger. Ie:
Code: Protected Sub btnCancelYes_Click(sender As Object, e As EventArgs) Handles btnCancelYes.Click DeleteRecord() End Sub
I have code that needs to run in two deployments. Let's call them deployment H and deployment W.
The code is already running in deployment H, and there's an aspx page and an aspx.cs code-behind file. The code is compiled for framework 2.0 which is the lowest common denominator of the two deployments. Deployment H has its own logos and styling which are coded in its aspx file.
Deployment W now wants to use this same page, but it wants its own logos and styling. There are also additional fields on the page that deployment H doesn't need.
I think it's easier to maintain one code base which is why I want the same code-behind file, but I am having trouble figuring out how to set this up in Visual Studio. Orginally, I was going to have two projects, one for W and one for H, but I'd have to make the same changes to both files when some of the common areas changes.
I created an image button in my header template. When clicked, it calls the Sorting method. When I change the image url in code behind, it does not render. By setting a break point, I can see the property being updated, but I assume it is getting overridden by the default I set in the HTML page.
I am writing a web application and one of the save routines calls another sub routine as passes two parameters byref. the sub routine gets the data required and assigns it to the passed parameters.
When I look at the results in the main sub the passed parameters are not set, why?
Code: Private Sub GetSiteDefaults(ByRef sCleanerCode As String, ByRef sCheckerCode As String) Dim sqlDASites As SqlDataAdapter Dim sqlDTSites As DataTable Dim sqlDCData As New SqlConnection sqlDCData.ConnectionString = conStringHQ.ConnectionString.ToString sqlDCData.Open()
I'm using an Ajax ConfirmButtonExtender to pop up a message box when a button is clicked. But I don't want it to appear only when the button is clicked.
I only want it to appear at specific conditions. But if I add it to the markup during design time, it's going to be automatically assigned to my button. So even if I change the text server side, the default message appears first and I have to click the button a couple of times for it to register the new message.
I also can't create the extender and add it to the markup during runtime, because I'd have to use the button to add it. So the button would need to be pressed twic.
Code: Dim obj1 As New TreeNode obj1.Value = 1 obj1.Text = "Level" & obj1.Value Dim obj2 As New TreeNode obj2.Value = 2 obj2.Text = "Level" & obj2.Value
[Code]...
Can I somehow create a function that creates the nodes instead of I need to make Dim ... each time? If I have 300 nodes this is not a good solution.
I have tried something like this but it doesn't work:
Code: Function CreateObj(ByVal no As Integer, ByVal name As String, ByVal obj As TreeNode) As TreeNode obj.Text = "Level" & no obj.Value = no treeview1.Nodes.Add(obj) Return obj End Function
I'm working on the following aspx file, and for some reason VS2010 is messing with my code. I have no idea why, and was hoping one of you could have a look at it.
What happens is that most of the times when I hit ctrl+s, it add some code to the end of the file.
