I tried binding a ListBox to an Object Data Source, but I can’t get the field to show up in the Data Source Configuration Wizzard for the ListBox. I got it working programatically populating the listbox using the DataReader but I’d like to be able to use the Object Data Source (Unless there are compelling reasons not to that I haven’t heard of yet.)

View 2 RepliesI am having 3 ListBoxs(LB1,LB2,LB3).In LB1 I am binding the names of Courses through database.The code is shon below...
da1 = new SqlDataAdapter("SELECT COURSE_ID,COURSE_NAME FROM Course_Mst", con);
DataTable dt1 = new DataTable();
da1.Fill(dt1);
lstCourse.DataSource = dt1;
lstCourse.DataValueField = "COURSE_ID";
lstCourse.DataTextField = "COURSE_NAME";
lstCourse.DataBind();
Whenever I select particular course in LB1 all the content related to that course will be binded in LB2.The code is shown below.....
protected void LB1_SelectedIndexChanged(object sender, EventArgs e)
{
da2 = new SqlDataAdapter("SELECT SPEC_ID,SPEC_NAME FROM SPEC_TRANS WHERE COURSE_ID="+Convert.ToInt32(lstCourse.SelectedValue)+"", con);
DataTable dt = new DataTable();
da2.Fill(dt);
lstSpecilization.DataSource = dt;
lstSpecilization.DataValueField = "SPEC_ID";
lstSpecilization.DataTextField = "SPEC_NAME";
lstSpecilization.DataBind();
lstSpecilization.Focus();

{
ListItem li = new ListItem(lstSpecilization.Items[intLoopIndex].Text, lstSpecilization.Items[intLoopIndex].Value);
LB3.Items.Add(li);
}

how to get the text...
When adding list item the Value field is being set to the Text field. Initially I though the problem was related to the input parameter for the primary key ( group_type_id ) as it is configured as OUTPUT variable.
Interesting enough, when I Watch all of the values, everything is correct.
So for example, I'll watch these:
ddr["group_type_name"] comes out as "Dept"
ddr["grouptypeid"] comes out as 4
When the item is created however,
itms.TEXT = "Dept"
itms.Value = "Dept" <-- THIS IS THE PROBLEM
I'm at a loss why the listbox values are being set to the text values when I can clearly see the data reader values are correct. ?
Code sample here:

I'm using a ListBox to display fairly long text items (500 characters). If an item is too long it will go out the side of the ListBox and not be fully displayed. How can I get items in the ListBox to wrap? Also, is it possible to put some sort of separator between each item?

View 3 RepliesI am using AntiXss library 4.0 for encoding text before displaying on the asp page.

I need to display the contents of a file selected from a ListBox into a text box. When I populate the ListBoxItems, I set the Text property to the name of the file and its full path to the Value property.
When I click the item, the page refreshes because AutoPostBack is on, but nothing happens. I then tried this:
VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged   Me.txtServiceTag.Text = Me.lbLogs.SelectedItem.TextEnd Sub
But it still didn't work.

View 1 RepliesI 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.

Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged

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?
