I have an ASP.Net page with VB.net code-behind.

I have a number of telerik controls on the page like the RadMenu, RadButtons, RadTextBox, RadLabel, etc.

The page has a dark near black background.

I have just added the telerik RadioButtonList.  My default skin for all my ASP.Net pages is Office2007.

With the Office2007 skin, the text of the items in the RadioButtonList is Black.  I need the text of the items to be White.

How to override the forecolor of the text of the items without affecting the other telerik controls on the page?

 

Sincerely,

Keith Jackson

Im creating a treeview on client side and there is a requirement of adding multiple radio buttons columns dynamically.

How can I achieve adding multiple columns client side with proper alignment. I couldnt find any article showing how to add radio button columns.

 

 node = new Telerik.Web.UI.RadTreeNode();
                    node.set_text(msg.d[i].Text);
                    node.set_value(msg.d[i].ID);
                    var dataItem = msg.d[i];
                    node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.WebService);
                   objTree.get_nodes().add(node);

Hi Team,

In RadTreeView, I want to add an image at right side of the node text for all the nodes in Client- Side.

Description:
1. Dynamically, I am adding nodes in the client side and here I wanted to place an image at right side of the node text(find attached for how I wanted) and I tried with "farimage" property, Image index property as the value of "1" and tried with many ways. But, all are not working out.

In one way, I am able to achieve this, If I append an image with the text. But, I am getting an error ("A potentially dangerous Request.Form value was detected from the client ") while post occurs.

I would be helpful if you send me an example.

I have a radgrid defined which contains a GridCheckBoxColumn.  Our accessibility evaluation tool is complaining because the input (checkbox) does not have a label associated with it.  I have EnableAriaSupport set to true on the radgrid.  I currently have a work around, which applies an "aria-label" attribute to the input in the idem created event.  But I'm hoping you can provide a better solution.  I'm including the column definition and my work around code below.

                            <telerik:GridCheckBoxColumn 
                                UniqueName="Active"
                                DataField="Active" 
                                HeaderText="Active" 
                                AllowFiltering="false"
                                >
                            </telerik:GridCheckBoxColumn>

 

    Protected Sub grid_ItemCreated(sender As Object, e As GridItemEventArgs)
        If TypeOf e.Item Is GridDataItem Then
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

            If TypeOf item("Active").Controls(0) Is CheckBox Then
                Dim Ctrl As CheckBox = DirectCast(item("Active").Controls(0), CheckBox)

                Ctrl.InputAttributes.Add("aria-label", "Active")
            End If

        End If
    End Sub

I am using RadPanelBar throughout my site and it works fine.  But suddenly when I try to add another one on a user control, I get some weird behavior.  The expandmode I'm using on the site is MultipleExpandedItems and that's what I would like to use in this user control.  I've spent hours on this and have tried to approach it from different directions.  I'm finally at the point where I copied the demo from Telerik and still getting the weird results.  Here's my current test user control.

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestUserControl.ascx.cs" Inherits="UserControls.TestUserControl" %>
     <div>
        <telerik:RadPanelBar runat="server" ID="RadPanelBar1" ExpandMode="MultipleExpandedItems">
            <Items>
                <telerik:RadPanelItem Text="Panel 1">
                    <Items>
                        <telerik:RadPanelItem Text="Item 1" />
                        <telerik:RadPanelItem Text="Item 2" />
                        <telerik:RadPanelItem Text="Item 3" />
                    </Items>
                </telerik:RadPanelItem>
                <telerik:RadPanelItem Text="Panel 2">
                    <Items>
                        <telerik:RadPanelItem Text="Item 4" />
                        <telerik:RadPanelItem Text="Item 5" />
                        <telerik:RadPanelItem Text="Item 6" />
                    </Items>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>
    </div>

The panels render as collapsed and when you click on them nothing happens.  However, when I change the ExpandMode to SingleExpandedItem then suddenly it works.  Why does it only work on SingleExpandedItem mode in my user control but not in MultipleExpandedItems mode?  And why does MultipleExpandedItems work everywhere else on my site?

I am looking to print a TreeList without having the dependency of Excel or PDF. Is there a method other than exporting the innerHTML onto a page and printing the new page?

We have a radScheduler and we want the users to right-click to bring-up a context menu in order to edit.  This allows us to present a set of choices specific to the day or the appointment they are editing.  It gives us greater control.

We do not want them to be able to double-click the day or appointment.  We want double-clicking to do absolutely nothing.

How can this be accomplished?

I have a radGrid with EnablePostBackOnRowClick="True".

it includes an OnSelectedIndexChanged event: OnSelectedIndexChanged="grdSpecialtyMedTasks_OnSelectedIndexChanged"

It includes a column :<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" ItemStyle-Width="20px"/>

My codebehind includes :

protected void grdSpecialtyMedTasks_OnSelectedIndexChanged(object sender, EventArgs e)
{                                                       // when I click a row, I hit this code every time
GridDataItem selectedItem = (GridDataItem)grdSpecialtyMedTasks.SelectedItems[0];
DropDownList ddlDest = (DropDownList)selectedItem.FindControl("ddlDest");
if (ddlDest.SelectedValue != "Default")
    {
    btnProcessTask.Enabled = true;
    }
...

protected void btnProcessTask_Click(object sender, EventArgs e)
{
if (grdSpecialtyMedTasks.SelectedItems[0] != null) // occasional index out of range error hits here
     {       
    processTask(sender, e);
     }
}

---------------------------

When user selects anywhere in the row, the client select checkbox is checked and vices-versa, so that seems to work nicely.

Also when either of the above happens I can see that the OnSelectedIndexChanged fires as I hit a breakpoint each time. (double click hits breakpoint twice.)

Problem is that the row does not APPEAR to have been selected / does not get highlighted until the user double-clicks the row. WHY?

In case it matters, both times when I hit breakpoint in the OnSelectedIndexChanged method, IsPostBack is set to True.

The potential is that the user thinks they are processing Row X when in fact they are processing Row Y.

Also, occasionally I am getting am index out of range error in the btnProcessTask_Click method.

--------------------------

Any assistance greatly appreciated :)

hi

How do I do a foreach loop in the RadScheduler ItemDataBound event?

I have a code here would like to have a lightGray background color if the class end time is lesser than current time and i would like to loop through each item so that gray out the correct items. Thanks

 

 protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)
    {
        DataRowView row = (DataRowView)e.Appointment.DataItem;
        DateTime endtime = DateTime.Parse(row["ClassEndTime"].ToString());
        if (endtime <= DateTime.Now)
        {
            e.Appointment.BackColor = System.Drawing.Color.LightGray;
        }
              


    }

I have set up a page using <telerik:RadAjaxManager> and <asp:Panel>. The <asp:Panel> is ajaxified.

Within the <asp:Panel> I have a button. This button is supposed to "escape" the AJAX mechanism and reload the whole page via PostBack when being pushed.

What do I need to do to have the button reload the whole page, not just the <asp:Panel> area?
