Adding Multiple Selected Values to ListBox Dynamically

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :ASP.Net

I have a ListBox control that gets populated from a database like this:

For Each gvr As GridViewRow In GridView1.Rows
                Dim lb As ListBox = CType(gvr.FindControl("SectionsListBox"), ListBox)
                For Each sect As String In sectionlist


Then the selected values also get populated like this:

For Each gvr As GridViewRow In GridView1.Rows
                Dim lb As ListBox = CType(gvr.FindControl("SectionsListBox"), ListBox)
                Dim faqid As Integer = gvr.Cells(0).Text
                selectedlist = oCMS.getFAQSections(faqid)
                For Each sect As String In selectedlist
                    lb.SelectedValue += sect


I need to have multiple selections, but I cannot get it to select multiple values with this line "lb.SelectedValue += sect".  The listbox has been set in aspx to allow multiple selections.

Adding multiple usercontrols dynamically


Hi all,

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.

I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?

I've looked high and low but can't find anyone with a similar problem/solution. 

Any help is much appreciated,

Pass Checkboxlist control multiple selected values to SQL table



I wanted to know if it is possible to pass multiple selected values from Checkboxlist to SQL table so each selections goes into separate row in the table.

I tried it using the following code (to pass ShowDate value) but it enters value only if I make one selection. It gives me an error message if I make two selections and try to pass it to SQL.


string showdate = string.Empty;

foreach (ListItem li in BirmShowDates.Items)
            if (li.Selected)
                showdate += li.Value;


            string sql = "INSERT INTO [BShow] ([Single], [UserId], [ShowDate], [Half]) VALUES (@Single, @UserId, @ShowDate, @Half) SELECT [Single], [UserId],  [ShowDate], [Half] FROM [BShow] WHERE [BShow].[ShowDate] = [BShow].[ShowDate]";

            SqlCommand cmd = new SqlCommand(sql, conn);

cmd.Parameters.AddWithValue("@ShowDate", showdate.ToString());


Thank you.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Persist data in a dynamically populated ListBox in a user control


Hi All,

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details

I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.

My Click Function

Adding carriage returns between 2 dynamically created controls in an HtmlTableCell


The title pretty much explains it. Here is what i'm trying to do...

 Private Sub LoadGrid_CommentsField(ByVal Row As HtmlTableRow, ByVal BookingNumber As String, ByVal CommentsText As String)
  Dim Txt As TextBox
  Dim Cmd As ClickOnceButton.ClickOnceButton

  Txt = New TextBox
  Txt.ID = "txtComment_" & BookingNumber
  Txt.CssClass = "TFAppControls"
  Txt.TextMode = TextBoxMode.MultiLine
  Txt.MaxLength = 500
  Txt.Width = New Unit(95, UnitType.Percentage)
  Txt.Text = CommentsText

  Row.Cells(cComments).InnerHtml &= "<br/>"

  Cmd = New ClickOnceButton.ClickOnceButton
  Cmd.DisableAfterClick = True
  Cmd.Text = "Save Comments"
  Cmd.ID = "cmdSaveComments_" & BookingNumber
  Cmd.CssClass = "TFAppButtons"
  Cmd.EnableViewState = False
 End Sub

On the line where i try and update the InnerHtml, i get the following error; "Cannot get inner content of  because the contents are not literal."

BDC Column with Ability to Select Multiple Values


Use Case:

We are creating a storage location for technical product articles. These will be SharePoint publishing pages. Each page will have metadata assigned to it to make it searchable by properties. The possible values for one of the columns (Part Number) could potentially be sourced by our ERP system. I'd like to do this to eliminate the possibility of free-text entry errors, but there are probably over 10,000 parts so a drop-down list isn't feasible.


Ideal Situation:

The end user enters the part number and clicks a button to verify it against a BDC entry from our ERP system. If they weren't sure on the part number they needed, they could do a lookup from that metadata entry screen. They'd need to have the option to add multiple part numbers as one technical product article could reference multiple part numbers.



Is BDC an option for all of this or am I looking at a custom metadata solution? I thought I heard along the way that BDC only supported one value choice, but I couldn't find a verification for that in the forums.

Retain DropDown,TextBox's previously selected values after redirected from another page.


 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   



 Update: I've come up with this code. But the problem is The values are being retained but the Button_Click event is not being handled properly. When i Check the code even after this "DropDownList1.SelectedValue = Session["Name"].ToString();" DownList1.SelectedValue is EMPTY"" samw with DropDownList2 . please Suggest something


    protected void Page_Load(object sender, EventArgs e)
        if (IsControlsEmpty())
            if (SessionExist())
                DropDownList1.SelectedValue = Session["Name"].ToString()

jQuery modified ListBox not posting back modified values


Hi everyone,

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:

        $("#MyList_btnAddAll").click(function(e) {
        $('#MyList_lstAll option').appendTo('#MyList_lstSelected');

The code has two ListBoxes in fact, one a "source" and the other a "destination".  As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected.  These are rendered in the browser as <select> elements, as you'd expect.

The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback. 

I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data?  But in the codebehind after postback the ListBox contents haven't changed.  Does anyone know what might be going on and what I can do about it?  Many thanks.

How to create a dynamically populated items in a listbox and use it as a navigation?

Hello, I am trying to create navigation inside a listbox menu. I load data from xml to populate a list. Each item in the list box should be a link or button.
