I have a form and if the user checks a box or clicks a certain item in the listbox, I need a new form to be generated, with a certain form name in the same format, and the prior form to be locked for editing.

How to get selected value form Listbox
View 6 Repliesthis should be pretty simple but I can't find a solution. I spent a bunch of time, without luck, searching for an answer that makes sense (to me).
Here is the problem. I have an asp form in a frame (I know frames are considered evil, but this part is non-negotiable) This form has an asp:listbox that is tied to a SqlDataSource. A button on this form opens a second form that allows the user to add records to the SQL table that is bound to the SqlDataSource object (the source of the listbox in the first form) The thing is, that when the user closes the second form and returns to the first, the list box needs to be refreshed and I have no idea how to do that.
My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
The user has to select from the ListBox to populate the DataGrid control. However, the Default value in the ListBox does not cause the DataGrid to be populated. Why is this?

i am develope one webpage in that user can select multipule checkboxs inside the listbox? any examples?

im having difficulty with a project I'm working on. The project has many data tables however it's three that im concerned with. The tables are applicants, position applied for and positions. In one part of the project I have created a formview which inserts users to our applicants table. This is working fine however now I want the option within the formview for users to be able to select from a checkbox list the positions that they are applying for. I want to pull data from the positions table and the current formview and insert that information to the position applied for table. The primary key for "Applicants" is CSVC, PK for "Positions" Table is PositionID, Key for "Position applied for" is CSVC and PositionID.
View 5 RepliesIs it possible to populate a listbox from a textbox on another form? Ive tried searching google but have had no luck.
View 6 RepliesI am trying to allow for multiple selection check boxes that are created dynamically.
The Following code is written for each row in the dataTable (I print it as HTML code)
<input type='checkbox' name='multiCheck' id='chk{1}' value='{1}' runat='server'/>
however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?
protected void DeleteSelection_Click(object sender, ImageClickEventArgs e)
{
int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected.
}
New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1:
userID
fname
lname
etc...
Table2
userID
categoryID
subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?

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

I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?
<div class="subHead">Stock Options</div>
<table class="settingTable">
<tr>
<td colspan="2"><b>Limited Stock</b></td>
</tr>
[Code]....
How do I make it so that the validator for the stock count wont run unless the limited stock checkbox is checked?
I have a GridView displaying names from a DB and I have added a checkbox to each row to select certain candidates (code below). This data then gets posted to another page which is where my problem is...What I'd ideally like is to have the CandID value stored against chkSelect in the form so I can then work out which candidates are selected. However, what I actually get in my form is 'gvCands$ctl159$chkSelect=on' for instance. It's not particularly easy
to figure out which candidate is #159 so I'm guessing that's the wrong route to go.
I own a business that has locations in multiple cities around the US. I want to create a system that generates each business dynamically from the database.
Example: www.mybusiness.com/california-location
My goal though - is to map the california-location to it's own domain --- i.e. www.californiabusiness.com
Is this possible? and how do i go about setting it up?
I have a view with a form..this form has a textbox and a checkbox in it.
i also have a submit button in the form which points to an action in a controller.
my question is..how can i pass the values in the textboxes and the checked state of the checkboxes to the controller action? the textboxes and checkboxes are not tied to a model.
I have the following code, i add code for required validator, but when you make selection from dropdown to create the table, the page generates an error. Should the logic be somewhere else to add it to the table? i mean, dont they have to be there so when you submit the form, it fires the validation?
