Headerless Grid?

Is there a simple way to remove the header entirely from a grid?

I had assumed a simple Visible="false" or perhaps Height="0px" would do the trick, but the header seems quite persistent in displaying itself, and I am at a loss. Anything simple I am missing?

Thanks!

RadGrid checkbox printscreen issue

Hi. I am using a RadGrid on a page that allows users to select multiple options from checkboxes in the grid. The problem arises when users try to do a printscreen of the page after making their selections (but before submitting the page): the grid prints correctly, but in the printout all checkboxes are unchecked, which is their initial state.

Is there a way to capture the checked state of the checkboxes inside a RadGrid for a printscreen? Note that all other functionality is fine; the only issue is with the printscreen.

Thank you!

A potentially dangerous Request.Form value was detected from the client when updating node text from editor

Hi Telerik Support staff,
I have the following issue,
I have a Treeview populating perfectly with server side code, and changing the node text using the editor.content client side.
I set up a web service to handle load on demand and I end up with the following error:

A potentially dangerous Request.Form value was detected from the client (RadTreeView1_ClientState="...:{"text":"<span style=\"color:...").

I load the root nodes from server side, however I add nodes clientside and change the node text client side:

string connectstr = SqlConnect;

SqlConnection Sqlconnect = new SqlConnection(connectstr);

string sql = "Select TemplateID, TemplateLineID, TemplateNodeOrder, SectionID, ParentTemplateLineID, NodeLevel, NodeText "+

"From TemplateNode " +

"Where ParentTemplateLineID is null "+

"Order By SectionID ";

SqlDataAdapter adapter = new SqlDataAdapter(sql, connectstr);

DataTable dataTable = new DataTable();

adapter.Fill(dataTable);

RadTreeView1.WebServiceSettings.Method =

"LoadNodes";

RadTreeView1.WebServiceSettings.Path =

"TemplateLoadOnDemand.asmx";

foreach (DataRow row in dataTable.Rows)

{

RadTreeNode node = new RadTreeNode();

node.Text = row[

"NodeText"].ToString();

node.Value = row[

"TemplateLineID"].ToString();

node.ExpandMode =

TreeNodeExpandMode.WebService;

RadTreeView1.Nodes.Add(node);

}

My settings for the treeview are :

<

telerik:RadTreeView ID="RadTreeView1" Runat="server" EnableDragAndDrop="true"

onnodedrop="RadTreeView1_NodeDrop" EnableDragAndDropBetweenNodes="True"

onclientnodedropping="nodeDropping" OnClientContextMenuItemClicking="OnClientContextMenuItemClicking"

MultipleSelect="True" OnClientNodeEdited="OnClientNodeEditedHandler"

Skin="Outlook" OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick"

CheckChildNodes="True" onnodeedit="RadTreeView1_NodeEdit"

style="white-space: normal;" PersistLoadOnDemandNodes="true" OnNodeDataBound="RadTreeView1_NodeDataBound"

OnClientNodeClicked="OnClientNodeClicked" >

I did the following to resolve the error but continue to get it....

In Script Manager I set

EnablePartialRendering="False"

Everything works when I don't use the webservice, client side calls and server side calls are perfect.... Its when I load the webservice that I start throwing errors. The web service loads the child nodes fine... Editing or adding is a big issue when using the web service.

Thank you in advance for your help.

[Solved] Problem with OnClientKeyPressing with EnableLoadOnDemand

I have a RadComboBox that I'm using to allow users to perform assisted searches. As they type in the combo box field, "search assist" values are populated in the drop down section. The user can either hit enter (or click a search button) or select one of the values in the drop down to perform a search. Let me rephrase and emphasize that the user can either use their freely entered text or select one of the suggested search terms.

If the user hits the enter key, I am capturing this with the OnClientKeyPressing event. Most of the time this works fine but the event fails to fire if I hit enter at the exact moment I see the "Loading..." text in the drop down. If I hit enter a fraction of a second before or after the loading text, it works normally.

Here is my combo box:

    
            <telerik:RadComboBox ID="ddlTextSearch" runat="server" Width="200px" CssClass="SearchControl" 
        
                        AllowCustomText="True" EnableLoadOnDemand="True"   
        
                        ShowDropDownOnTextboxClick="False" ShowToggleImage="False" 
        
                        onclientitemsrequesting="ddlTextSearch_ItemRequesting" 
        
                        OnClientKeyPressing="ddlTextSearch_HandleKeyPress"   
        
                        OnClientSelectedIndexChanged="ddlTextSearch_SelectionChanged" ZIndex="9900">  
        
                        <WebServiceSettings Method="GetCompletionList" Path="~/TextSearchAutoComplete.aspx" /> 
        
            </telerik:RadComboBox> 
        
            <script type="text/javascript">  
        
                        Telerik.Web.UI.RadComboBox.prototype._onInputCellClick = function(e) {  
        
                            if (this._enabled) {  
        
                                //  if (this.get_text() !== this.get_emptyMessage())  
        
                                //       this.selectText(0, this.get_text().length);  
        
                                if (!this.get_dropDownVisible() && this._showDropDownOnTextboxClick)  
        
                                    this._showDropDown(e);  
        
                                return true;  
        
                            }  
        
                        }  
        
            </script>

Here is my js method:

    
             function ddlTextSearch_HandleKeyPress(sender, eventArgs)  
        
                    {  
        
                        if(eventArgs.get_domEvent().keyCode == 13)  
        
                        {  
        
                            var combo = $find("<%= ddlTextSearch.ClientID %>");  
        
                            var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");  
        
                            if (combo && combo.get_highlightedItem() != null)  
        
                            {  
        
                                ajaxManager.ajaxRequestWithTarget("<%= ddlTextSearch.UniqueID %>","<%= WebUtils.HttpRequestEventArguments.SearchAssist %>");  
        
                            }  
        
                            else 
        
                            {  
        
                                ajaxManager.ajaxRequestWithTarget("<%= ddlTextSearch.UniqueID %>","<%= WebUtils.HttpRequestEventArguments.Search %>");  
        
                            }  
        
                       }  
        
                    }

As you can see, I need to differentiate between selecting an item from the drop down list and the freely entered text.

Again, everything works except when I hit enter while I see the "Loading..." text in the drop down portion of the combo box. When I hit enter at that time, the event is not fired and nothing appears to happen. How do I handle this scenario with your control?

Hebrew view (right to left mode)

We encountered some problems in telerik controls when using it for Hebrew view (right to left.(

1. When adding scroll option to RadGrid, the header row is not shown well, as can be seen in image 'radgrid scroll' attached.

The code in aspx specifying the scroll is:

2. In Scheduler control, the scroll appears as default, and again the header row is not shown well, as can be seen in image 'rad Scheduler' attached.

Extending the last column (IE)

Hi,

Let's suppose that there is a grid (RadGrid, of course) which has all its columns with explicitly, absolutely defined width (e.g. in pixels). Then, we make this grid wider than the total width of all its columns. When using Firefox, Chrome etc. the last column automatically extends to the right to fill all remaining space. But IE doesn't do it - the last column remains as wide as it is defined.
Is there any way to force the last column to fit the remaining space even under IE?

Best regards
Tomasz

[Solved] AjaxLoadingPanel Skin

I would like to set the skin for all of the loading panels in my app to the simple skin. In the web.config I have the following code.

    
            <appSettings> 
        
                <add key="Telerik.AjaxLoadingPanel.Skin" value="Simple"/>  
        
            </appSettings>

Instead of the loading panel appearing with the simple skin, I am just getting a blank space white space where the loading panel should be.

Thanks

EnableCreateNewFolder property doesn't enable option

Hello,
I am trying to setup the RadFileExplorer to allow creating folders. However, when I set EnableCreateNewFolder to true, the create folder option doesn't appear as it should. I am wondering if this could partly be because I am using a custom FileProvider class. Can someone please help me with this? Thanks.
