Adding Checkboxes Inside Listview Dynamically From Code Behind?
Mar 16, 2011
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 trying to check dynamically generated "checkbox" value inside Listview.
I can reference non-dynamic checkboxes exact in same location (index) inside Listview using "e.Item.FindControl", however I can't reference dynamic checkboxes.
i want to know how to add checkboxes in listview (e.g: Approve / Dissapprove) and save it to database. i need to submit today
here is my code: Â For Each item In ListView2.Items Dim chk1 As CheckBox = item.FindControl("CheckBox1") Dim chk2 As CheckBox = item.FindControl("CheckBox2")
I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
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 have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
how to do this when the checkbox in listview layout template check select all checkboxes in listview itemtemplate.I dont give 'Eval 'field to checkbox present in itemtemplate.
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.
i was reading this post about adding the meta tags dynamically by code in asp.net 4 - but i need to ask what is the good for SEO , adding it static or no problem with adding it in code behind http://weblogs.asp.net/scottgu/archive/2010/01/05/asp-net-4-seo-improvements-vs-2010-and-net-4-0-series.aspx
I want to create a Dynamic aspx Page in current solution through code-behind..forexample i have a 2 text-boxes one for page-Title another another for page-Content and a button.. whenever that button is pressed, An aspx Page should be created in current solution and should be included in the current solution
Now there are five items in the ItemTemplate of this repeater..what i want is to set class of each of the anchor tags as "mySprite id1,mySprite id2 , mySprite id3 and so on.."
for that I did this in code behind...
for (int i = 1; i < 6; i++) { Name.Attributes.Add("class", "sprite id" + i); }
Now when I view page source, ALL my anchor tags have got class set as class="sprite id5"
i'm currently learning .Net and i can get data out of a database and display in a listview. But how can i access data items in the code behind and format, change, concatenate...do whatever i want to them then display in the list view? Is it even possible?
[Code]....
Maybe an example of what i'm trying to do would be to concatenate a address from the dataset and in a variable sAddress and then attach sAddress to a label in the list view, or add to colums of the dataset together and then show in a label in the listview.
I have checkboxes in one column of listview and outside the listview I have one dropdown and one button.
when I dont check any checkboxes in listview fire a validation "Select any one checkbox" on button click.
simirarly when I check Checkboxes in listview and I'm leaving to select dropdown fire a validation"Select any item in the dropdownlist" on button click.
how to validate both controls(checkboxes in listview and dropdown) when those are not selecting.
I have a listview with paging.Every paging has 10 rows with with a username, an email and a checkbox.
I need to be able to check a couple of checkboxes, in different "pagings", press a button and send an email every to ever user that has been checked.
Trouble is I don't really know how to remember the selected checkboxes between each paging-press.
Deos anyone have a similar solution or a few tips on how to do this? I'd prefer to solv this without jQuery, but ordinare javascript or a C# solution works fine.
Does anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.
I try to datbind a listview which is inside another listview InsertItemTemplate.
[Code]....
I'm binding the listivew in the parent listview onitemcreated events. I receive the error Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have checkboxes in listview item template and one checkbox outside the listview.when I check checkbox(outside listview) that should be validate all checkboxes in Listview.
I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?
I know this not the right place to ask javascript related questions.
But I dont understand how else to get the answer.
I have built an application using asp.net 4.0 and entity framework. I have implemented the routing feature introduced with the .Net 4.0 version.
Now, I have a page which will fetch products from the database and display them in a listview. For the paging purpose I have used the DataPager.
I had a really hard time making the paging feature work with DataPager as it is not fully compatible with the Routing feature(asp.net 4.0).
Now I want to give the user the option to select multiple products to compare. For this purpose I have placed a checkbox with everyproduct.
Now the problem:
I dont know how to find which checkbox was selected. i want to find the checked checkbox using javascript.
I have binded the list of products to the listview at two occasions; once directlly to the listview in page load and second time during the pre_render event of the dataPager. (As I said I had a really hard time to get this combination to work; Listview+DataPager)
I have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.
Example:
chkbox State Name donation new donation chkbox CA Sam 10 15 chkbox AK Sam 15 20
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET? Do I have to write the table in .aspx with 50 <tr> tags, and then have VB.NET code populate it? Can I otherwise dynamically write these checkboxes from VB.NET code?
