Select List - Set the selected value

Posted By:      Posted Date: October 05, 2010    Points: 0   Category :ASP.Net

I am attempting to set the sletected value of a selectlist

ViewData["CompanyLocationID"] = new SelectList(
                , "CompanyLocationID"
                , "LocationName"
                , Convert.ToInt32(localCompanyLocationsContact.CompanyLocationID));

I have tried to set the value to an integer and to a string and just pass it in regular, but no matter what it never sets the selected value.  Is there something i am doing wrong?

Dropdown list in ASP.NET - How to get value selected

am sure this must be very simple, but unforunately I can't figure it out.
I have the following code which populates the dropdown lists from the database. This works fine. Now, when the user selects a particular employee name from the list, I want to get the Employee Id of the selected employee. i.e. I need to get the "Eid" value. I can do this if the EId is loaded in the dropdown list, but in this case only the employee name is displayed. Please let me know howI can get the Eid value even though it is not loaded in the dropdown list.
I would really appreciate your help

Treeview: Select all children if Parent is selected etc...



I'm using a Treeview with  ShowCheckBoxes="All" , so basically I have a tree with all CheckBox Nodes. I'm using the TreeView inside an update panel, and populate the Tree code behind dynamically.

My requrements are the following:

1) Select all the children if parent is selected,

2) When parent is selected, and if we de-select a child, set parent unselected

3) Track if new nodes were selected and previously selected nodes were de-selected (becasue I need to update the database according to the selections in the Tree)

For above 1, I do the following:

protected void TreeView1_TreeNodeCheckChanged(object sender, TreeNodeEventArgs e)
        foreach (TreeNode node in TreeView1.Nodes)
            TreeNodeCollection col = node.ChildNodes;
            //select all children when the parent is checked
            if (col != null && node.Checked)

Use BDC data in list as multi-select column

I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?

External List - Access Selected Items

Hello, The situation;- An external list in SP 2010 from SQL A custom ribbon/button that calls via JS a Dialog box(Application page) and passes the selected items IDs Some code behind to process items after confirmation from user. Question is how to access the selected items in the code behind. As far as I can tell the JS 'getselecteditems' only returns the list ID, which in the case of a standard list is fine, but with an External list returns something like '_B00234' - how do I use this or how to return a more meaningfull ID? (I would rather work in my confort zone VB/C# than JS to process items) casey

Hello All,   We are facing an error in our MOSS 2007 internet site.   We are unable to access the root site ,however all other site collections created using manged path under the root site are accessible.   The home page of the root site i.e http://servername/pages/default.aspx  navigates to custom error page , where as application pages like settings.aspx ,viewlsts.aspx throw below mentioned error   "List does not exist  The page you selected contains a list that does not exist.  It may have been deleted by another user" As a workaround , we tried restoring the rootsite from back up file (.dat) ,but we get the same error (mentioned above).   Content database is very much present and database server has good enough memory.   Any suggestions for this would be of great help.  

How to get selected text of a drop down list in MVC?

I aggressively googled around, but could not find the information I am looking for.  I know how to populate a dropdownlist using my view model and Html.DropDownListFor helper method.Suppose the drop down list contains U.S. stateId and stateName key value pairs.  Suppose my ViewModel looks likepublic class MyViewModel{      public IList<State> States {get; set;}      public int SelectedStateId {get; set; }}public class State{     public int StateId {get; set; }     public string StateName {get; set; }}Now, in my controller's action method:[HttpPost]public ViewResult Index(MyViewModel  myViewModel){     // This following line seems to work fine, myViewModel automatically      // picks up the selected item of the drop down list.  How does this work?      // Is this the so-called model binding?      int selectedStateId = myViewModel.SelectedStateId;      // But, then, how do I get the selected state name?     string stateName = ??????????????     ... ... }Do I have to change my implementation of my view model?  In any case, how to get the selected item text of the drop down list?  Any hint?  Thanks a lot.

How to update selected item state in the list box by clicking a button?

I created a listbox menu to browse through content by clicking items in the listbox. I also created ‘back’ and ‘forward’ type of navigation to browse through the same content based on the browsing history. I load content into frame and accessing the browsing history with NavigationCommands.BrowseBack and BrowseForward Properties. It is working great. However, I need to indicate a selected state of the listbox item related to the content shown in the frame while browsing with Back/Forward buttons. I have a hard time binding that property. What is the correct way to bind selected state of the listitem in this case? Thank you in advance. XAML: Button <Button x:Name="NavBack" Content="" HorizontalAlignment="Left" Margin="20,0,0,0" Style="{DynamicResource BackButtonStyle}" VerticalAlignment="Top" CommandTarget="{Binding ElementName=ContentFrame}" Command="{x:Static NavigationCommands.BrowseBack}" SnapsToDevicePixels="True" IsEnabled="{Binding CanGoBack, ElementName=ContentFrame, Mode=OneWay}" > XAML: Listsbox <ListBox x:Name="Nav_ListBox" Margin="0,18,0,0" ScrollViewer.HorizontalScrollBarVisibility="Hidden" Background="#FFF2F2F2" ItemsSource="

Insert a "Select User" row in Linq for a dropdown list

I'm new to Linq. I have searched and searched the web for a soluion, and can't find anything. I have a Linq query and I want to insert a row ("Select User") to the top before I pass it to the drop down list. I've been trying to use the Union but to now avail (it keeps telling me that my object doesn't support the Union method). My code, prior to attempting to inser a row, is very simple.public SelectList DropDown_Users()        {            var context = new VivarianDataContext();            var query = from t in context.AspnetUsers                        select new { t.UserId, t.LastName };            list = new SelectList(query.AsEnumerable(), "UserId", "LastName");            return list;        }Now I try to insert a row and I found this on the internet and it seems to say that his solution will work. But it is filled with syntax errors. http://magicode.wordpress.com/2009/08/20/inserting-an-item-in-iqueryable-object-using-union-met

Multivalue parameters - Changing label if (Select All) is selected

I'm using SSRS 2005.  I have a report which has a multi value parameter.  When you click (Select All) the text in the parameter combobox shows all the names of the possible values.  Since this is my default it really looks tacky and hard to read. Is there a way I can have the text in the multi value parameter combobox say "ALL" or something else when (Select All) is checked?

Troubleshooting an XSL Select to another List in a Dataview.

I've done this before to join in some column from another List into a dataview.    I've looked over the two list and  this line of code for a few hours now. It's producing no output, when I know there are matches. <TD class="{$IDASV40H}">    <xsl:value-of select="/dsQueryResponse/Applicant/Rows/Row[@ID = current()/@ApplicantID]/@AName"/></TD> None of the colums or lists have been renamed. None of the columns have spaces in the names. I want to make sure I'm reading this right.  do I need to define current()? Any bood way to troubleshoot this in Designer? any issue with trying to compare @ID? Thanks.

XSL Lookup to another List in a View. Joining in data from another List. xsl:value-of select=

I've been able to create a DataView with data joined from two SP Lists. I did this using SPD, a linked Source, and doing joined subviews.  The technique works nicely, but I have to create my DataView from scratch.As an alternative, I took an existing AllItems View in SPD, converted it to XSL, and was able to add a column from another List as follows:   <TD Class="{$IDA1VDGH}" style="width: 62px; height: 23px"><xsl:value-of select="/dsQueryResponse/Master/Rows/Row/@Lastname" />The problem is, it reports the column for the first row everytime. I'm new to XSL and was wondering..    using XSL, and preserving all the original columns already in the View, is there anyway to make the added column smarter, maybe with a filter?I noticed in my working example, I have this filter (I guess where the subview join magic is)            [@Title = $dvt_ParentRow/@Key] which does not resolve syntax:I tried this, but it does not work, only finding one match, and it also seems to get set for the entire Dataview and not just the column.     [../../../Master/Rows/Row/@Title = @Key] I guess I'm looking either for the SPD steps, or XSL code for adding a single column from another list, joined in by a column in both lists.Thanks for any help or information.
