When I type a long paragraph until the vertical scroll bar appears and then press enter key the scroll bar jumps up and I need to scroll it down to continue typing. It happens when the NewLineMode is set "P". It works fine NewLineMode is set to "Br".

hide/show column client-side by uniquename or datafield

I know you can hide columns client-side using masterTableView.hideColumn(columnIndex). However, this leads to very difficult to maintain code since column ordinals can change frequently. Is there a way to find a column by UniqueName or DataField client side and then call .hide() or show() functions, or set_visible() , or something to that effect?

Accessing the items of a ClientItemTemplate

I have the following Combobox setup on my page:

<telerik:RadComboBox ID="cbxDup" runat="server" Width="350px" DropDownWidth="375px" Height="340px"

Skin="Default" HighlightTemplatedItems="True" MarkFirstMatch="true"

AutoPostBack="True" EnableLoadOnDemand="True" EnableVirtualScrolling="True">

<HeaderTemplate>

<h2>Codes</h2>

</HeaderTemplate>

<ClientItemTemplate>

<ul class="Main">

<li><span> #= Text # </span></li>

<span> #= Attributes.Description # </span>

</ul>

</ClientItemTemplate>

<WebServiceSettings Method="LoadComboBox" Path="SysProf-Add.aspx" />

</telerik:RadComboBox>

With the following server code:

<WebMethod()>

Public Shared Function LoadComboBox(ByVal context As RadComboBoxContext) As RadComboBoxData

Dim data As DataTable = Nothing

Dim comboData As New RadComboBoxData()

Try

data = GetData()

Dim itemOffset As Integer = context.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + 100, data.Rows.Count)

comboData.EndOfItems = endOffset = data.Rows.Count

Dim result As New List(Of RadComboBoxItemData)(endOffset - itemOffset)

For Each dr As DataRow In data.Rows

Dim itemData As New RadComboBoxItemData()

itemData.Value = dr.Item(0)

itemData.Text = dr.Item(1)

itemData.Attributes.Add("Description", dr.Item(2))

result.Add(itemData)

Next

comboData.Message = GetStatusMessage(endOffset, data.Rows.Count)

comboData.Items = result.ToArray()

Return comboData

Catch ex As Exception

Return Nothing

End Try

End Function

What I would like to do is access the Description attribute in the cbxDup.SelectedIndexChanged event?

Thanks in advance

Passing parameters after calling code behind function

Hi everybody, I hope someone of you can give a hand. I will post some sample code however they are pretty much what I am trying to do.

I have a button which executes both client side (OnClientClicking) and server side (OnClick) events. The point is that from the client side I execute a PageMethod in order to get the result of a calculation. Up to this point everything is OK but here comes the tricky part.

I need to check for the result in order to determine if it is greater than some value. If this condition is true then I ask the user to confirm if he wishes to continue, so if the user says YES then the code continues executing OnClick event but if user says NO then OnClick must not be executed.

I have tried passing teleriks args as a parameter but it is not working (OnSuccess function receives it as null). I do this in order to call args.set_cancel() method.

Here is the code at client side

01.function btnCallback_Clicking(sender,args)

02.{

03. var num = parseInt( prompt("Enter an integer number", "1") );

04.

05. PageMethods.multiply(num, function (response, args){ TheSuccess(response, args); });

06.}

07.

08.function TheSuccess(response, args)

09.{

10. //alert(' TheSuccess: \nResult obtained was: ' + response);

11. if (response > 70) {

12. var cancel = !confirm("Result obtained was greater than 70 ¿Continue?");

13. args.set_cancel(cancel);

14. }

15.}

Here is the code at server side

01.[System.Web.Services.WebMethod]

02.public static int multiply(int num)

03.{

04. int res = num * num;

05. return res;

06.}

07.

08.protected void btnCallback_Click(object sender, EventArgs e)

09.{

10. string extra = "User agreed to do this";

11. btnCallback.Text = extra;

12.}

Any ideas about how to achieve this.

Thanks in advance.

RadEditor.ImageEditor CSS issue.

Hi, I have implemented a custom FileBrowserContentProvider for Azure and customized the file bowser by following the steps on the “Editor - Customize Built-in Dialogs” article (http://demos.telerik.com/aspnet-ajax/editor/examples/externaldialogspath/defaultcs.aspx).

Everything is working well but the image editor is not rendered properly (check the attached files).

<telerik:RadEditor
    ID="RadEditor1"
    RenderMode="Classic"
    LocalizationPath="~/App_GlobalResources/Controls_Editor"
    ContentFilters="MakeUrlsAbsolute"
    DocumentManager-MaxUploadFileSize="11000000"
    OnFileUpload="RadEditor1_FileUpload"
    OnFileDelete="RadEditor1_FileDelete"
    ExternalDialogsPath="~/Controls/TelerikEditorDialogs/"
    runat="server">
    <Tools>
        <telerik:EditorToolGroup Tag="FileManagers">
            <telerik:EditorTool Name="ImageManager"></telerik:EditorTool>

[Solved] RadListBoxItem not rendering HTML

hello,
I just recently upgraded Rad Controls for ASP.NET AJAX from the Jan 14, 2010 (2009.3.1314) version to the Apr 15, 2010 (2010.1.415) version. I am using a RadListBox that I was adding items to wrapped in a <span> tag for formatting purposes. After the upgrade the span is rendered as text. I looked briefly through the version history and didn't see anything mentioning this change specifically. Is there something I can do in the latest version to pull this off?

Here's the listbox definition:

    
            <telerik:RadListBox runat="server" ID="rlbOrderList" Width="495px" Height="320px" 
        
                                                            AllowDelete="False" AllowReorder="False" Skin="Default" CssClass="cert" AutoPostBack="True" 
        
                                                            OnSelectedIndexChanged="rlbOrderList_SelectedIndexChanged">  
        
                                                        </telerik:RadListBox>

Here is what I am adding to it:

    
            foreach (eSolutions.HomeHealth.Core.ReadOnly.Order ord in ol)  
        
                        {  
        
                            rlbOrderList.Items.Add(new RadListBoxItem("<span class='" + ord.OrdersDisciplineCode + "'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</span><b>" + ord.OrdersDisciplineCode + ":</b>&nbsp;" + ord.OrderDescription.Trim(), rd.OrderID));  
        
                        }

I've attached screenshots of before and after the upgrade.

Thanks in advance for your response,
Bryan Smouse

[Solved] FilterCheckListEnableLoadOnDemand property

Hi everyone,

I'm trying to create a grid with filterchecklist .... I tried to enable the "FilterCheckListEnableLoadOnDemand" property for GridBoundColumn so i can use "OnFilterCheckListItemsRequested" event handler to load the items of the checklist.
However, "FilterCheckListEnableLoadOnDemand" is not supported by the trial version of telerik.web.ui that I downloaded from your site, so I can not use this property until i purchase the latest version of the library or is there some other reason why it does not work?

Thanks in advance.

[Solved] Telerik Treelist NeedDataSource doesn't load data

I'm trying to load treelist, everything works well but i always see "No Records To Display".

Here is the control:


<telerik:RadTreeList ID="trlProductGroups" runat="server" AllowPaging="true" PageSize="5"
        DataKeyNames="ID" ParentDataKeyNames="PARENT_ID" AutoGenerateColumns="false"
        OnInsertCommand="trlProductGroups_InsertCommand" OnNeedDataSource="trlProductGroups_NeedDataSource"
        OnUpdateCommand="trlProductGroups_UpdateCommand" OnDeleteCommand="trlProductGroups_DeleteCommand">
        <Columns>
            <telerik:TreeListEditCommandColumn UniqueName="InsertCommandColumn" ButtonType="ImageButton"
                HeaderStyle-Width="60px" ItemStyle-HorizontalAlign="Center" />
            <telerik:TreeListEditCommandColumn UniqueName="EditCommandColumn" ButtonType="ImageButton">
                <ItemStyle CssClass="MyImageButton" />
            </telerik:TreeListEditCommandColumn>
            <telerik:TreeListButtonColumn UniqueName="DeleteCommandColumn" Text="Delete" CommandName="Delete"
                ButtonType="ImageButton" />
            <telerik:TreeListBoundColumn DataField="ID" UniqueName="ID" HeaderText="Grup ID"
                ReadOnly="true" />
           <%-- <telerik:TreeListTemplateColumn DataField="GROUP_NAME" UniqueName="GROUP_NAME" HeaderText="Grup Adı">
                <EditItemTemplate>
                    <asp:TextBox ID="txtGroupName" runat="server"></asp:TextBox>
                </EditItemTemplate>
            </telerik:TreeListTemplateColumn>--%>
            <telerik:TreeListBoundColumn DataField="GROUP_NAME" UniqueName="GROUP_NAME" HeaderText="Grup Adı" />
            <telerik:TreeListBoundColumn DataField="PARENT_ID" UniqueName="PARENT_ID" HeaderText="Ana Grup ID"
                ReadOnly="true" />
        </Columns>
    </telerik:RadTreeList>


And here is the NeedDataSource Code:

 protected void trlProductGroups_NeedDataSource(object sender, TreeListNeedDataSourceEventArgs e)
        {

            WebAppTest.Objects.ProductGroups pGroups = new WebAppTest.Objects.ProductGroups();
            DataTable dt = pGroups.SelectData(null, string.Empty);
            trlProductGroups.DataSource = dt;
        }


I can see the data in DataTable, but treelist wont load data. Is there any mistake i make?


Thanks

TreeList
