How can I update the database with more than one item selected from the List Box. What I am currently doing updates only one item
objprp1.plugin_id = Convert.ToInt32(ListBox1.SelectedItem.Value);//passing the value(id) of the plugin thru the listbox property
I have a asp:ListBox wrapped inside an asp:UpdatePanel. The list box contains Bus Codes. If I select AH, for example, and then scroll down to select XY, the listbox jumps back up to the top of the list instead of staying on XY. Listbox's autopost back is set to True. As I need to get selected values and then pass it to another web page to display a crystal report. The report web page is opened using JavaScript Window.Open and on page load of the web page that contains the listbox this JavaScript is added to a button. Is there a way I can stop my list box jumping back to the 1st item?
View 13 RepliesI 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.
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?
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've a list box which may contain 300000 or more records. I've another listbox . The user basically selects from the first listbox and adds to second lbx. There is button which when clicked will move the selected records from first listbox to second listbox.
Now if I select around 45000 records and try to move to second listbox .. it moves fine . If I select more than 45000 or so...it takes very long and eventually i get the "Action Cancelled". When I put a break point in page_init ..it does not hit. Is there a way I can restrict the user by selecting more than 40000 items. ie they should not be able to highlight more than 45000 records.
I have a dataTable that contains a specific column from a database. A listbox contains 100 list items in it. When page loads, I need those listbox items to be selected, whose value matches the value in the datacolumn of the datatable.
Following is the code i tried, but is not working. For some reason, it selects only the last item in the datacolumn.
if (datTableRelatedSchool.Rows.Count == 0)
{
}
else
{
foreach (DataRow row in datTableRelatedSchool.Rows)
{
foreach (DataColumn myCol in datTableRelatedSchool.Columns)
{
lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString();
}
}
}
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)

I have a listBox that is bounds its content from the database. This control is inside an itemTemplate. When the item template is boudned, I want to select the corresponding value.
I have this ugly single line of code:
[Code]....
What it does is to select the right value to a ListBox that is databinded with values inside a DetailsView
here is the rest of the code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource4"
EnableModelValidation="True" ondatabound="DetailsView1_DataBound">
<Fields><asp:TemplateField><ItemTemplate>
<asp:ListBox ID="lbATechAuthCheck" runat="server" Width="100%" DataSourceID="SqlDataSource2" DataTextField="status" DataValueField="id"></asp:ListBox><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString
%>"SelectCommand="SELECT * FROM [Status]"></asp:SqlDataSource>
</ItemTemplate></asp:TemplateField></Fields></asp:DetailsView>
Is there an easier way to achieve the same thing perhaps without any code behind?

View 1 RepliesI have a drop down box with values that shows on loadUnited States Canada Now I have a function that is checking the users value from the database which is fired on a button click. What I plan on doing is comparing the string like if United States(db value) == United States (dropdown value) then go ahead and select United States in the drop down. When I do this I am getting the right value selected but it is making all the values the same for all records.

View 3 RepliesIn my project requirement user wants to enter a manual entry if they can not find an item in the drop down list.
Right now what I am doing is:
I set the dropdown list autopost back true and on selectedchanged event I am hiding the drop down list and showing a text box to enter a manual entry...
This is working perfect and no problems..
but the drop down list needs to change to a text box on only selecting a "unknown" option in the list...all other list items are doing unnecessary post back to the server with no use...
I'm trying to figure out some alternate ways of dealing with a smaller subsets of records from a larger set of records. This would be to increase performance and make it easier for the user to navigate, as opposed to trying to navigate a really large unwieldy record set. I know of a few ways a user can select a record from a record set. Selecting from a Grid View, drop down list, list box are some the first ones that come to mind. Another way I've seen, I think it was done with a repeater or User Control, is to list all of the letters in the alphabet as links and then only return the records that correspond to the letter that was selected.
It could also be done to allow the user to search by last name, first letter of the last name or some other similar method. I'm curious if there are any other ways of doing this. Does anyone know any other techniques that would create a better user experience when selecting a record or subset of records from a large record set?
I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.

I've been searching the web and no luck. Can someone tell me how to assign values to my listbbox? I used the ValueMember property but when i have more than 1 item it is only set to one value member instead of each of its own.

I apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work.The error:
Dim ddl As DropDownList = CType(sender, DropDownList)
Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)
Dim rowID As Integer = dgi.ItemIndex
The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)
if any body select listbox then
item=item1
if nobody select list box
item=no
how to do it
I 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.
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?
