Web service binding issue with the "id" attribute

Hi,
I'm trying to implement drag & drop from ListView to TreeView. I need to assign a custom value on the "id" attribute so it can be used in ListView's DestinationHtmlElement in RadListViewItemDragDropEvent. If I bind the tree nodes on the Server-Side with RadTreeNode type, everything works fine. But if I use Web Service with RadTreeNodeData type, the DestinationHtmlElement is empty. Do I need to do something different with the web service?

// Server Side with RadTreeNode type works fine

var node = new RadTreeNode();

node.Attributes.Add("id", "folder_" + dtrReader["folderID"]);

// Web Service with RadTreeNodeData type and the DestinationHtmlElement is empty

var node = new RadTreeNodeData();

node.Attributes.Add("id", "folder_" + dtrReader["folderID"]);

Problem with IE and CSS

Hi
I have a problem with the FileExplorer. In I use a template for my webapplication. When I look the site on firefox or chrome the fileexplorer works without problems. But in ie8 or 9 it doesn't work. I have attached some screenshots. My code looks so:

<telerik:RadFileExplorer Skin="Vista" ID="radfileexplorer" VisibleControls="AddressBox,ContextMenus,Grid,Treeview,Toolbar" Height="500px" Width="800px" runat="server">

<Configuration

ViewPaths="~/Uploads/Linkdaten"

UploadPaths="~/Uploads/Linkdaten"

DeletePaths="~/Uploads/Linkdaten"

/>

</telerik:RadFileExplorer>

I have found out, that the fileexplorer has a problem with my css-style. When I put the code in a new webform, it works fine.

Is there a possbility to define, that the fileexplorer should ignore all css from my page?

Thank you for the help!

Set Dock Title bar height using JavaScript

Hi,

I am having one request.
I need to set / change Rad Dock Title Bar height using javascript in both Collapsed or expanded position.
I can do this using CSS but my requirement is little different. I need to show and hide some of the title bar elements on click of a button using Javascript.

I tried this using div element and height do get chagned but the elements after dock are getting under it.
I want it as when the title bar height gets changed it should be relative as all other elements down page should move down by that height.

So here is the summary of the req.
1. Need to set / change Rad Dock Title Bar height using javascript in both Collapsed or expanded position.
2. When height gets set, the elements in line or below should get moved down by that height.

Expected early reply,
Thanks,
Avi

RadGrid CheckBox ia always false

This one is driving me insane and is probably a simple fix. All i'm trying to do is foreach(griditem) and if that control is checked process it on a button click, but all the checkboxes are false.

The GridView is created using AutoGenerateColumns, however in the aspx I push a checkbox column in before hand. Everything looks great just this always false is kiling me.

foreach (GridDataItem gdItem in RoleNamePageNameAddGrid.MasterTableView.Items)
            {
                CheckBox chk = (CheckBox)gdItem.FindControl("CheckBoxAdd") as CheckBox;
                if(chk.Checked == true)
                {
                }

            }

<telerik:RadGrid ID="RoleNamePageNameAddGrid" runat="server">
        <MasterTableView DataKeyNames="PageDefn">
            <Columns>
                <telerik:GridTemplateColumn HeaderText="Update">
                    <ItemTemplate>
                        <asp:CheckBox ID="CheckBoxAdd" runat="server" AutoPostBack="false" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>
    <telerik:RadButton ID="AddPageRoleAttachmentButton" runat="server" Text="Add" OnClick="AddPageRoleAttachmentButton_Click">
    </telerik:RadButton>

I can display Total Item Count on footer. But I can't export that number to Excel.

Hi,

I used following code to get the total item count to display on the footer:



int RowCount; 
protected void RadGrid1_ItemEvent(object sender, GridItemEventArgs e) 
{ 
    if (e.EventInfo is GridInitializePagerItem) 
    { 
         RowCount = (e.EventInfo as GridInitializePagerItem).PagingManager.DataSourceCount; 
    }  
} 
  
  
protected void grd_ItemDataBound(object sender, GridItemEventArgs e) 

{  
    if (e.Item is GridFooterItem) //Set footer text  
    { 
        RadGrid grd = (RadGrid)sender; 
        GridFooterItem footerItem = e.Item as GridFooterItem; 
        footerItem["LastCol"].Text = "Count: " + RowCount.ToString(); 

    }
} 





However, when I export the grid to the Excel, the count is show as 0 in excel file (Count: 0).

Is there any workaround on this issue?



Thanks

Pinned windows and CPU usage

Have a major problem with RadWindows that are pinned.

When opening a RadWindow (either clientside or serverside) and pinning it caused the clients CPU usage for iexplore.exe to go up. When the window is not pinned the CPU usage will generally be 0, but as soon as we pin the windows the CPU can increase by as much as 8% and stay there until we unpin it.

Completely baffled by this behaviour. Just to test it wasn't something I introduced I created a very basic new web application, added simply the scriptmanager, radwindowmanager and 1 radwindow to the page. We added a simple page to load in the radwindow.

I then pinned the window and the CPU usage went up and stayed up, unpinned it and the CPU usage went down.

Heres the example we used...

    
            <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="TestRad._Default" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server"> 
        
                <title></title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                    <telerik:RadScriptManager ID="RadScriptManager1" runat="server"  
        
                        OutputCompression="AutoDetect"> 
        
                    </telerik:RadScriptManager> 
        
                    <telerik:RadWindowManager ID="RadWindowManager1" runat="server"> 
        
                        <Windows> 
        
                            <telerik:RadWindow runat="server" VisibleOnPageLoad="true" Visible="true" Behavior="Maximize, Minimize, Pin" InitialBehavior="Pin" NavigateUrl="WebForm1.aspx"></telerik:RadWindow> 
        
                        </Windows> 
        
                    </telerik:RadWindowManager> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

...and the window to load...

    
            <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="TestRad.WebForm1" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server"> 
        
                <title></title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                hello world 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

No code behind is on either form. Absolutely annoying.

We did some snooping and located a possible area where the issue is happening. Seems to be getting stuck in one of the telerik script resource files. We notice ValidateParameter was being called constantly after the pinning though we didn't have the time to debug fully.

Additional fields for comments etc...

I am following the example for resource availability but I can't figure out how to store additional text fields (Phone, BookedBy) for the appointments. I don't need them as drop down selectable resources, I need simple text entry. Is there a way to do this?

Here is my sql data:
<asp:SqlDataSource ID="AppointmentsDataSource" runat="server" ProviderName="System.Data.SqlClient"
ConnectionString="<%$ ConnectionStrings:MCHPEVENTS %>" SelectCommand="SELECT [SchedulingID], [Start], [End], [Subject], [BookedBy], [Phone], [RoomID] FROM [RS_Scheduling]"
InsertCommand="INSERT INTO [RS_Scheduling] ([Start], [End], [Subject], [RoomID], [BookedBy], [Phone]) VALUES (@Start, @End, @Subject, @RoomID, @BookedBy, @Phone)"
UpdateCommand="UPDATE [RS_Scheduling] SET [Start] = @Start, [End] = @End, [Subject] = @Subject, [RoomID] = @RoomID, [BookedBy] = @BookedBy, [Phone] = @Phone WHERE (SchedulingID = @SchedulingID)"
DeleteCommand="DELETE FROM [RS_Scheduling] WHERE [SchedulingID] = @SchedulingID">
<DeleteParameters>
<asp:Parameter Name="SchedulingID" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="SchedulingID" Type="Int32" />
<asp:Parameter Name="Start" Type="DateTime" />
<asp:Parameter Name="End" Type="DateTime" />
<asp:Parameter Name="Subject" Type="String" />
<asp:Parameter Name="RoomID" Type="Int32" />
<asp:Parameter Name="BookedBy" Type="String" />
<asp:Parameter Name="Phone" Type="String" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="Start" Type="DateTime" />
<asp:Parameter Name="End" Type="DateTime" />
<asp:Parameter Name="Subject" Type="String" />
<asp:Parameter Name="RoomID" Type="Int32" />
<asp:Parameter Name="BookedBy" Type="String" />
<asp:Parameter Name="Phone" Type="String" />
</InsertParameters>
</asp:SqlDataSource>

floating data issue

Hello everyone,

I want to partially generate an HTMLchart in codebehind.
Here is what i got :

ASPX :

<telerik:RadHtmlChart ID="CHT_samples" runat="server">

</telerik:RadHtmlChart>

in my .CS file :

AxisItem o_xItem = new AxisItem();

i_gridLines =9;

for (i_incrementA = 0; i_incrementA < i_gridLines; i_incrementA++)

{

// Add the mold number as the X label

o_xItem = new AxisItem();

o_xItem.LabelText = "#" + o_sampling.LST_MOLDS[i_incrementA].NUM;

CHT_SAMPLESCHART.PlotArea.XAxis.Items.Add(o_xItem);

}

This is working perfectly, i get the labels on my chart.
But when i create a serie and decide to add data ...

LineSeries o_xMax = new LineSeries();

o_xMax.Name = "Max";

CHT_SAMPLESCHART.PlotArea.Series.Add(o_xMax);

CHT_SAMPLESCHART.PlotArea.Series[0].Items.Add(16.85m);

I get 2 points on my chart : one for "16" and the other for "85".
Is this a bug or am i doing it wrong ? Or both ? :p

Many thanks.

This is the same when i try to reproduce your static example :(
