I have a listbox which populated from using a datatable. I have a Add button in my page. On clicking the add button I want to insert a blank row in the listbox. This can be done easily by
ListBox_Admin.Items.Add("");
after this is done I want to select this item as in setfocus on this item.How do I do this.
Ok so I have two listboxes on my page one for users and another for cases. For some reason the users listbox preserves state, but the cases listbox doesn't.
They're both set EnableViewState= true
Code:
<asp:ListBox ID="ExistingUsers" runat="server" Width="45%" Height="189px"
CssClass="createdusers" ></asp:ListBox>
<asp:ListBox ID="ExistingCases" runat="server" Width="45%" Height="190px"
></asp:ListBox>
I tried setting them both to autopostback, but that didn't work. The users listbox would preserve the selected item, but make it the first viewable item in the list. The cases listbox still reset the selected item to the first.
My page load:
Code:
'....
If Not Page.IsPostBack Then
''Sort later.
Dim i As Integer = 10
For Each usr As String In AttRoleProvider.GetUsersInRole("Role1")
Me.ExistingUsers.Items.Add(usr)
[Code]......
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?
I 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();
}
I am having a ADD button.In LB2 I can select multiple items.When I select multiple items in LB2 and click on ADD all the selected items will be binded into LB3.The code is shown below...
protected void btnAddCourseDetaisl_Click(object sender, EventArgs e)
{
for (int intLoopIndex = 0; intLoopIndex <lstSpecilization.Items.Count ; intLoopIndex++)
{
if (lstSpecilization.Items[intLoopIndex].Selected)
{
ListItem li = new ListItem(lstSpecilization.Items[intLoopIndex].Text, lstSpecilization.Items[intLoopIndex].Value);
LB3.Items.Add(li);
}
}
}
My problem is when I select a item from LB2 and click on ADD the selecteditem is added to LB3 but if I select the same item and click on ADD the items are again added to the LB3.I want to prevent this.Pls respond me ASAP.
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

There are quite a few questions around this topic,but I can't seem to get it figured out.I'm trying to bind a listbox to an ObservableCollection and keep the listbox updated when items are added to the collection.
[code]...
Beyond this, I have a simple textbox and button on a page.When a name is entered into the textbox,and the button is clickedI call the addBlog(passing in name from textbox) sub routine in the ITRSBlogs Class (back up the page a bit) to add the item to the collection.Problem is,when I add an item to the collection,the listbox is not updated.I'm new to Observable Collections (and many other things : ),so maybe I'm just really off here.
how can i change the text of last moved item from one listbox to another
View 2 RepliesI have up and down arrows next to a listbox and i need to switch the actual index of the item.
It is very similar to this thread: [URL]
But what actually I want is, if the listbox is like
item1
item2 (selected)
item3
So after clicking on down button it should display the listbox in following way
item1
item3
item2(selected)
The selected item should move downwards.
regarding this scenario..
I have a listbox, i am binding it to a datatable with DataTextField and DataValueField. This is in WebForm (not windows).And the first item in ListBox is "Select All" and the rest are from DataTable.SelectAll is selected by default.1) If i select any other item...(as it is multiselect) the "select all" item should be unselected.2) If i select 5 items in ListBox and after that i select "Select All" items then all the other items except "Select All" item should be unselected.
I have a textbox that searches the listbox below it and selects the text that I types in the textbox. Now although the item is selected in the listbox I have to scroll to the end to see if the item is selected ornot
IS there a way that I can make the list box scroll to the selected item?
how can i check with jquery that an item is selected or not in listbox?
View 2 Repliesis there an easy way to scroll an ASP.Net ListBox automatically to the first selected Item? The ListBox has SelectioMode="Multiple".
<asp:ListBox ID="LbSymptomCodesEdit" CausesValidation="true" ValidationGroup="VG_SAVE" Height="100%" Width="100%" runat="server" SelectionMode="Multiple"></asp:ListBox>
The ListBox is in the EditItemTemplate of a FormView inside of an UpdatePanel. jQuery is possible but it would be great if there would be an asp.net serverside(or Ajax) way to achieve this because i don't want to use more client scripts than really needed(and this is only a nice to have).
In ASP.NET I have a dropdown with some items in it, I have a button and a textbox. I am subscribed to the SelectedIndexChanged event of the dropdown where I pass the new selected index of the dropdown to a struct that converts it's index (via enum) to a string. That string is then gotten through a property in a class to put into the textbox.
[Code]....
Now the problem I have is that, when you click it (the button) the first time, the action get's updated with the current action selected in the listbox, but then when you click the button again WITHOUT changing anything in the listbox, the textbox shows the zero'th item in the textbox, (seems to reset), although it actually hasn't changed at all.
I'm guessing this might have something to do with the postback caused by the button click, which resets the state of the global or something, but I'm not sure. Why is it being reset while the dropdown box is still as I set it the first time?
How can I pre-select a drop down list box item in a listbox? I experimented using Asp.net and C#, but was not able to pre-select a drop down listbox item.
I am not on my coding box right now, but basically as an example of what I am talking about, if I have the following drop down listbox items.
--Select--
New York Jets
New England Patriots
Green Bay Packers
Atlanta Falcons
SF 49'ers
Oakland Raiders
How would I pre select the team name of "Atlanta Falcons" using C# and Asp.net? Spefically based on the string of the team name "Atlanta Falcons" instead of an alternate way like using the Selected Index function?

View 1 RepliesI am trying to find the most efficient way to prefix listbox item text with their current index.I have two listboxes on a page, the first holds a list of states, the second holds the selection of states. When the user selects a state into the destination listbox, the state should be prefixed with the current index position. The destination box is sorted, and also has buttons to change the item positionsIs there a way to get the index of the item after insertion, instead of looping through the entire collection to add the index?
