SourceDragItems empty when Listbox dynamically binded.

Hi Telerik Team,

I use this link and found that this is a very good example of showing something into my product.
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/draganddrop/defaultcs.aspx

I open the code and implement the things as discussed in this particular page and found the things proper.

Now the problem is this that I bind the ListBox with the database and try to drag the listbox item from there into the textbox. but now it is giving me that in the function RadListBox_Dropped, e.SourceDragItems.Count become 0 every time.

I am writing my code here.

protected void RadListBox_Dropped(object sender, RadListBoxDroppedEventArgs e)
    {
        if (txtNoteArea.ClientID == e.HtmlElementID)
        {
            txtNoteArea.Text = String.Empty;
            foreach (RadListBoxItem item in e.SourceDragItems)
            {
                txtNoteArea.Text += item.Text + ", \n";
            }
            if (txtNoteArea.Text.Length > 0)
                txtNoteArea.Text = txtNoteArea.Text.TrimEnd(new char[] { ',', ' ', '\n' });
        }
    }
    public void BindStandardNotes()
    {
        DataSet dsMC = new DataSet();
        SqlConnection con = new SqlConnection(System.Web.Configuration.WebConfigurationManager.AppSettings["con"]);
        SqlDataAdapter adp = new SqlDataAdapter("SPNAME", con);
        adp.SelectCommand.CommandType = CommandType.StoredProcedure;
        adp.Fill(dsMC);
        lstStandardNotes.DataSource = dsMC;
        lstStandardNotes.DataValueField = "ID";
        lstStandardNotes.DataTextField = "TEXT";
        lstStandardNotes.DataBind();
    }

<telerik:RadListBox ID="lstStandardNotes" runat="server" Width="90%" Height="200px" SelectionMode="Multiple"
                                                                        AutoPostBackOnReorder="false" EnableDragAndDrop="true" OnDropped="RadListBox_Dropped" />
<asp:TextBox ID="txtNoteArea" runat="server" Wrap="true" Rows="8" TextMode="MultiLine" Width="90%" Height="200px" ValidationGroup="QAN" />

This code is working fine if I put some static items into the ListBox, but when I bind with the Database, the SourceDragItem count become 0.

Please assist me ASAP.

Regards,
Steve Austin

[Solved] RadGrid Set Column Navigation Property

Hello people...

I'm having a problem with my RadGrid...Can you show me how can i on my asp.cs file(code behind) set the column value of my grid with a navigation property field?

RadGrid1.DataSource = this.SapDocuments;

RadGrid1.

RadGrid1.UniqueID.Equals("Process") =

public List<SapDocuments> GetSapDocumentsByUser(string userName)

{

var documentsQuery = from sd in spDocs.SapDocuments

join ua in spDocs.UsersAssign

on new { sd.Staging.Process, sd.Priorities.Priority }

equals

new { ua.Process, ua.Priority }

where ua.UserName == userName

//ALterar User

select sd;

return documentsQuery.ToList();

}

I'm using Entity, and I have the a table SapDocuments with a foreign Key of the field Process to another Table "Staging",

At this moment my grid comes with Priority and Stagin values at null and the others are fine...

<MasterTableView GridLines="None" Width="100%" ViewStateMode="Disabled" CommandItemSettings-ShowExportToCsvButton="True"

CommandItemSettings-ShowAddNewRecordButton="false" CommandItemDisplay="Top">

<Columns>

<telerik:GridBoundColumn DataField="SequencialNumber" HeaderText="SequencialNumber"

UniqueName="SequencialNumber" SortExpression="SequencialNumber">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Priority" HeaderText="Priority" UniqueName="Priority"

FilterControlAltText="Filter Priority column" SortExpression="Priority" DataType="System.Int32">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Process" HeaderText="Staging" UniqueName="Process"

SortExpression="Process" FilterControlAltText="Filter Process column">

</telerik:GridBoundColumn>

I need to set those two column values with the value of my navigation property....I can access to it like that:

SapDocuments.Staging.Process;
SapDocuments.Priorities.Priority;

I needed to change my datamodel and know i have the exception for Priority and Process :

{"The ObjectContext instance has been disposed and can no longer be used for operations that require a connection."}

I have already set LazyLoad enabled...

RadPageView not getting 100% height

Hi,

I have below code structure. and also note that all my parent elements including body has 100% height defined as you mentioned in http://demos.telerik.com/aspnet-ajax/splitter/examples/resizewithwindow/defaultcs.aspx.

But RadPageView doesn't take the 100% height it only takes fixed heights.

<RadSplitter height="100%" width="100%" orientation="vertical">
<RadPane width="22%" height="100%">
Some contents goes here
</RadPane>
<RadPane width="76%" height="100%">
<telerik:RadMultiPage height="100%">
<telerik:RadPageView height="100%">
Some contents goes here
</telerik:RadPageView>
</telerik:RadMultiPage>
</RadPane>
</RadSplitter>

any special ways that I should use height attribute for the RadPageView ?

Thanks
Malinda

GridClientSelectColumn limitation

I found GridClientSelectColumn very limited if grid has pages. There are several problems with it.

1. Keeping selected checkboxes while paging. This doesn't work out of the box and I know there are workarounds posted. By the way, I believe Telerik documentation http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-client-sorting-paging-grouping-filtering.html should be updated, since the code simply doesn't work since the array of selected keys needs to be stored in a hidden field.
2. Selecting all checkboxes doesn't affect checkbox at the header. Again the workaround is posted, but I am wondering why isn't it part of the control? Having hundred lines of JavaScript in order to circumvent the limitations of the control, defeats the purpose of even using one.
3. And finaly the biggest roadblock is that checking the box at the header does not check items on all pages and I don't see a way around it since I couldn't find events for the header checkbox.

Maybe it is all by design since the name of the control is GridClientSelectColumn, but it sounds that if grid has pages, I will better off by doing checkboxes manually...
