Multiple Listbox Selection not working :(

Posted By:      Posted Date: September 17, 2010    Points: 0   Category :WPF
I'm loading a ListBox this way, which works and shows the selected items: lstCollectionsType.SelectedValuePath = "ClientCollectionTypeID"; lstCollectionsType.DisplayMemberPath = "ClientCollectionType1"; lstCollectionsType.ItemsSource = MyClient.ClientCollectionTypes; foreach (ClientCollectionType item in MyClient.ClientCollectionTypes) { if ((bool)item.Selected) lstCollectionsType.SelectedItems.Add(item); } And when trying to save the data, I do it as shown below. But it's not getting the current selected data. It's showing the data of how it was loaded. Make sense? It's not changing what is selected. foreach (ClientCollectionType i in lstCollectionsType.Items) { if (i != null) { ClientCollectionType boo = MyClient.ClientCollectionTypes.SingleOrDefault(c => c.ClientCollectionTypeID == i.ClientCollectionTypeID); if ((bool)i.Selected) boo.Selected = true; else boo.Selected = false; } } Please help! Thank you so much for your time!

This web user control consists of an ASP.NET AJAX HoverMenuExtender, JavaScript, StyleSheet and CheckBoxListExCtrl .

working with multiple data sets

i am new to ssrs and looking for guidance : i need to develop a report based on multiple tables: general ledger, customer ledger and customer master... the purpose of report is to have customer segment wise sales and expense information.... for given month and YTD. customer segments are defined in customer master, sales is in customer ledger and expenses are in general ledger.. the problem i am facing are: 1.

How to implement Bounding Box(Multiple selection of objects) and grouping as implemented in Photosho

ListBox/ListView Selection

We are implementing drag/drop on ListBox/ListView items with the extended selection mode. The extended selection mode allows multiple items to be selection simultaneously by holding the shift or control key while selecting additional items.   In Windows Explorer, when an individual item among a group of selected items is clicked, all of the other items are not deselected until the up-click event. This allows an individual to select the desired group and then click and drag this group as a whole to the desired destination.   In WPF, the group appears to be deselected and the individual item selected on the down-click event. This means that in order to drag a group of items, you must hold shift, click and hold the mouse on the desired range of items and then drag the group. If the group is selected first and then the mouse released, the individually clicked item is selected when a drag attempt is made on the group.   We are using WPF, but would like to see the Windows Explorer selection functionality. Any thoughts on how to reconcile these two implementations? The most straight forward fix would be a custom control, possibly derived from ListBox/ListView, but this seems like it might be reinventing the wheel. Seems like the WPF controls are not designed properly here.   Thanks.

WPF Datagrid with multiple row selection/checkbox column template

Hello, I am using the WPF Toolkit Datagrid with a checkbox defined in a template column/template cell. We are using the checkbox template so that selecting the checkbox will also highlight the row in the datagrid. Here is the template definition: <dg:DataGridTemplateColumn MinWidth="50" Width="Auto" Header="" CanUserReorder="False"> <dg:DataGridTemplateColumn.CellTemplate> <DataTemplate> <CheckBox IsChecked="{Binding Path=IsCheckedm, Mode=TwoWay}" /> </DataTemplate> </dg:DataGridTemplateColumn.CellTemplate> </dg:DataGridTemplateColumn> We are allowing multiple row selection in the datagrid and using MVVM (using MVVM Light). We would like to keep a list in the View Model of selected rows as they are selected/unselected. Any suggestions on how we can leverage MVVM to keep the list of selected/unselected elements current. Many Thanks --Sam

Multiple selection in connected list view webpart

Hi all, I have a webpart page with 2 listview webparts connected via  ("Send Row of Data"/"Get filter values from"). This connection permits me to select one row on the first listview (parent) and the second (child) gets filtered by the defined filter column. My question is how can I choose multiple rows on the parent so I can filter the rows of the child with multiple filter values? It seems on can only select one row via the "Select" column... Is there a workaround... Many thanks,  

Drop Down Listbox SelectedIndexChanged Event not firing when I programmatically change selection

I have two drop down listboxes (DDL1 and DDL2).  When DDL1 has an index change, DDL2 then has a refresh of list items based off SQL Server SELECT from a table.  The database isn't the problem.  Everything works perfectly when the user selects a new item manually from DDL1.But in my code, I save the user data from the selection of DDL1 in a separate table.  And then upon rendering of the page (Page_PreRenderComplete), I do a SelectedIndex assignment of the value of what's saved in the db table.  That works just fine, it selects the DDL1 item, but DDL2 is unaffected, as if DDL1's SelectedIndexChanged event isn't called like it would be if manually changed.  How can I get around this?Thanks in advance. :)

Adding Multiple Selected Values to ListBox Dynamically


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.


Multiple issues with dropdown list controls not working correctly


I am using WSS 3.0 and SharePoint Designer.  I have modified one of the items in my NewForm page so that I have a filtered lookup using a spdatasource. The filter works great, but my issue is that I can't seem to save the users selection back to the list itself.

Issue when using an ASP.NET dropdown list
I am able to bind the filtered spdatasource to an ASP.NET dropdown list control, however the item that is selected in the dropdown list is not being saved back to the list.  I am guessing that this is because the dropdown list itself is not tied directly to the appropriate list item, but... I can't seem to figure out how or where to do this.  I don't see anything in the data properties box in SharePoint Designer that allows me to tie the data back to the list itself.  Maybe I am just overlooking it somewhere?

Issue when using the native SharePoint Data View DropDownList with a filtered spdatasource
When I select "Data Fields..." on the dropdown control I get the Change Data Bindings dialog box.  From here I can select a data field to save the value back to (which resolves the issue noted for the asp.net control) and I can select my spdatasource, but... the display text and value fields below that never populate.  Thus, the dropdown list is empty when the user is filling ou

Multiple selection of items

I've pretty much created a custom itemscontrol and put in there some of my custom objects which are set up to look like rectangles which can vary in size. At this point, I am stuck on understanding how I would select multiple of these items within my collection of items or if this even possible. I keep on searching but I get no results. Btw, my rectangles are setup in a grid fashion which would span the size of a picture in the background.

Having multiple UpdateProgress controls working


I have an application that is using TabContainers and TabPanels. Within each TabPanel I have a DropDownList and a GridView. The GridView is filled on "SelectedIndexChanged" event.

I have managed to get UpdatePanel and UpdateProgress working for one on the instances but I do not seem to have luck implementing additional UpdateProgress controls for the rest on the application.

I have tried to use "AssociatedUpdatePanelId" but read that external trigger will not work. I've also tried to assign each UpdateProgress value of UpdatePanel in code behind (

UpdateProgress1.AssociatedUpdatePanelID = UpdatePanel1.UniqueID)

 , not working for me either:

I have created a Java SCript that hides GridView when UpdateProgress is being shown (works fine too)

This is what I have (and working):



<script type="text/javascript">
      window.onload = function() {
          var prm = Sys.WebForms.PageRequestManager.getInstance();
          if (prm != null) {
              prm.add_beginRequest(function(sender, e) {
                  var gridView = document.getElementById("<%=GridView2.ClientID %>");
                  if (gridVi

Multiple Approval Not Working using Site Content and Structure


Hi all

I have two dummy users. I have given one user contribute permissions and the other as approve permissions. I have enabled content approval on my document libraries, pages library etc. I have created a few pages,documents etc  using the dummy user having contribute permissions. Now using Site Content and Structure's pending approval section i am unable to approve these docs using the second dummy user having Approve permissons.

When logged in as dummy user 2 (having approve permissons) I am able to see all the documents requiring my approval in the pending approval section of Site Content and Structure. But when i check all the check boxes and click on approve its not getting approved. The page refreshes but the items still remain in the pending approval section without any change.

Please Help...

'Add Service Reference' not working for multiple include statements


I'm using VS 2010 (.NET 4.0) and I cannot use 'Add Service Reference' to generate my .NET proxy client since looks like using 'Add Service Reference' (svcutil.exe) option doesn’t work if there are multiple include statements for the schemas in the wsdl. Using "Add Web Reference" (wsdl.exe) option does work to consume this kind of wsdl but having issues passing UsernameToken.

My understanding is it generates WCF client only if 'Add Service Reference' option is used and not 'Add Web Reference'.

The web service is from the 3rd party, so I cannot modify it and they expect UsernameToken in the SOAP header.
