Using RadWordsProcessing in ASP.NET Application

Hi There,

I learned from the following documentation page that there is a RadWordsProcessing feature that can be used to manipulate docx files.

http://www.telerik.com/help/aspnet-ajax/radwordsprocessing-getting-started.html

However, it is also mentioned that reference to the following dlls is required.

• Telerik.Windows.Documents.Core.dll
• Telerik.Windows.Documents.Flow.dll
• Telerik.Windows.Zip.dll

Can I check with you whether it is recommended to reference dll under the namespace 'Telerik.Windows' in ASP.NET projects?

Regards,
Ryan

RadTreeView with Context Menu

Hi,
I have RadTreeView with context menu. The code looks like this.

    
            <telerik:RadTreeView ID="RadTreeView1" runat="server" Style="border: 1px solid #CBE7F5;" 
        
                             OnNodeExpand="RadTreeView1_NodeExpand"  
        
                             OnNodeClick="RadTreeView1_NodeClick"  
        
                             OnClientNodeClicking="OnClientNodeClicking"   
        
                             OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick" 
        
                             OnClientContextMenuItemClicking="onClientContextMenuItemClicking" 
        
                             OnClientContextMenuShowing="onClientContextMenuShowing" 
        
                             > 
        
                             <ContextMenus> 
        
                               <telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server"> 
        
                                    <Items> 
        
                                        <telerik:RadMenuItem Value="CR" Text="Create Change Request" ></telerik:RadMenuItem>                             
        
                                    </Items> 
        
                                    <CollapseAnimation Type="none" /> 
        
                                </telerik:RadTreeViewContextMenu> 
        
                             </ContextMenus>                  
        
                    </telerik:RadTreeView>

in the contextmenuitemclick event I am accessing the node like this

    
             protected void RadTreeView1_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e) 
        
                { 
        
                    RadTreeNode clickedNode = e.Node; 
        
            }

most of the times the returns a valid RadTreeNode, but after a few clicks or the page is left untouched for a while the e.Node returns null. I suspected Session timeout but it is not. Any ideas on how to resolve this or am I doing some thing wrong? please help.

How to use custom images

Can you please explain or provide an example of how to use custom images?

I am not referring to custom shapes, I would like to use an image such as a PNG as the shape, is this possible? I understand its possible with silverlight and wpf versions of the diagram but I'm using asp.net ajax

I can probably provide my images in the SVG format if that helps

Thanks

Refreshing Sessions to Avoid Timeout

I realize you can just go into IIS and extend the session, or you use javascript to keep the session alive, but I have been requested to find out if there is something within the telerik library specifically that can help with this - ideally something that works well with usergroups. Again I am aware that it can be done without telerik.

If there is, we would like to know about it.

Thanks.

Hi,

the default of GroupingDirection in AgendaView is Horizontal, which is fine.
But in this case it ignores the ResourceHeaderTemplate.
Is there a way to change the look of it?

Export to Excel (BIFF) from RadGrid

My data is exporting to Excel but the problem is the appearance of the Excel column widths. Currently, the result is the columns are very narrow and concealing some of the data. I have looked at the RadGrid documentation and demo and tried to follow it but I haven't seen, or comprehended, what would format the Excel column widths to fit the header column titles. I have tried scrolling through all the properties for MasterTableView, RowIndicatorColumn, and a few others but didn't seem to see anything that offered help with this issue. Is there a setting that would 'autosize' the width of the exported columns based on the content of the data in the HeaderText so that the user doesn't have to manually expand the columns before being able to view the contents? Thanks for any suggestions.

GridDropDownColumn: Pull a list not included in DataSource

So I have a RadGrid:

<telerik:RadGrid ID="RadGridPageDetails" runat="server" DataSourceID="dsReportPageDetail" AllowAutomaticUpdates="True" Width="100%" OnItemCommand="RadGridPageDetails_ItemCommand" OnItemDataBound="RadGridPageDetails_ItemDataBound"><br

>

    <

MasterTableView AutoGenerateColumns="False" DataKeyNames="ReportPageID" DataSourceID="dsReportPageDetail">

A bunch of Gridbound columns like so:

<telerik:GridBoundColumn DataField="PageName" FilterControlAltText="Filter PageName column" HeaderText="Section Name" SortExpression="PageName" UniqueName="PageName"

<ColumnValidationSettings

<ModelErrorMessage Text=""

/>

</ColumnValidationSettings>

</

telerik:GridBoundColumn

<telerik:GridBoundColumn DataField="PageTitle" FilterControlAltText="Filter PageTitle column" HeaderText="Section Title" SortExpression="PageTitle" UniqueName="PageTitle"

<ColumnValidationSettings

<ModelErrorMessage Text=""

/>

</ColumnValidationSettings

</telerik:GridBoundColumn>

Here I Created a GripDropDownColumn inside that RadGrid:

<telerik:GridDropDownColumn DataField="PageOrientation" EnableEmptyListItem="true" EmptyListItemText="--Select--" EmptyListItemValue="" ListTextField="Value" ListValueField="Value" FilterControlAltText="Filter PageOrientation column" HeaderText="Page Orientation" UniqueName="PageOrientation">

<ColumnValidationSettings>

<ModelErrorMessage Text="" />

</ColumnValidationSettings

</telerik:GridDropDownColumn>

And here I attempt to use codebehind to populate this griddropdowncolumn with the following values: Select, Landscape, Portrait.

protected void RadGridPageDetails_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

GridEditManager editMan = editedItem.EditManager;

GridDropDownListColumnEditor editor = editMan.GetColumnEditor("PageOrientation") as GridDropDownListColumnEditor;

DataTable dt = new DataTable();

dt.Load(SQLCalls.GetDropdownListValues("Page Orientation")); //This pulls "Landscape" and "Portrait"

editor.DataSource = dt;

editor.DataSource = new string[] { "Landscape", "Portrait" };

}

Both of the datasources I've tried don't work, and I believe it's because I'm not setting ListText and ListValue correctly. Can someone help me fix this so it will work?

Also, when I am in edit mode, I want it to start off selecting the current value, instead of defaulting to "Select".
