Data Controls :: Populate CheckBoxList From ListBox Data And Vice Versa
May 3, 2014
i have been trying to solve this issue for over a month and i tried many different things
i want my shopping cart list box to have items in it then I save all of those items in a session variable. I pull that session out on my checkboxlist page and I want it to autocheck all the items that were in my previous listbox that are now in the session
I also want to to this the other way so I can check a new item in my checkboxlist and I want it to automatically put the item in the listbox The issues I have been getting is a ListItem error or a List<Product> Error it does not work no matter what ways I try it
i have a masterpage and has some linkbuttons in it, i also have a webform which is a content page for the masterpage. i like to access the controls to the webform via the linkbutton residing in the masterpage or access the linkbuttons via the webform controls.
I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
Over here I have created a folder with name Data inside my solution, so the Server.Mappath("Data") as well the statemet for converting assigning the src property of the IFrame I1 is working properly. But I want to use the files from a folder which resides in a network folder like
Lets say I have ListBox1 (1,2,3,4,5,6) and a ListBox2 (A,B,C,D,E,F)..
and a Button and a GridView. Now when I click the Button. I want a GridView Column 0 to be populated by ListBox1 and Column 1 to be populated by ListBox2. . C# / Asp.net.
I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:
I have a listbox which I need to populate with the results from a stored procedure. I have a class Ethics and I can call my stored proc there but I don't know how to populate the listBox from this point on. Here's what I have so far:
i have a checkboxlist with a controlparameter. the flow of my page is
1) enter value into textbox eg: empid - 098765
2) on text box leave event ,im gettin data from db based on value enter in textbox and fill the labels in form
eg: select * from empmaster where empcode = '098765'
lblcode = MD lbldesignation = "Managing director'
3) based on the value filled in label am populating checkboxlisteps in text
select skill from behaviour where jobcode = lblcode.text (MD)
i have write all the above 3 steps in textbox_textchange event.Now i wanted to know after which event, checkboxlist will populate.coz iniside the textbox_text change event when i count the checkboxitems it always says 0.but it got items.so when it will populate checknboxlist?
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.
I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default Inherits System.Web.UI.Page Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged End Sub Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged End Sub Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click Dim SwapValue As String = "Sixty Pounds" Dim Counter As Integer = 8 Dim SwapN0 As Integer lstSwapList.Items.Add(SwapValue) lstSwapList.Items.Add(Counter) lstSwapList.Items.Add(New ListItem("300", "1")) lstSwapList.Items.Add(New ListItem("ASP.Net", "2")) lstSwapList.Items.Add(New ListItem("Programming", "3")) SwapN0 = lstSwapList.SelectedValue For Counter = 0 To -1 SwapN0 = lstContent.Items.Count Next End Sub Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click lstSwapList.Items.Remove(lstSwapList.SelectedValue) End Sub Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click End Sub End Class
======================================= Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)
