RadUpload - upgrade from older version questions

Hi,

I am upgrading VS2003 project created in 2007 with much older version of RadUpload control. New will be VS2010/Latest Telerik controls. It use to have CSS I could make control apperance changes. Now with latest upload control I can't find anything. I searched help for how to change control width in run time and help suggested to use MinWidth=.... I applied this in source but control remained same width in run time. How can I do this and why help suggestion doesn't work? Also clicking on any part of control poping up file select dialog, how to change it to popup file selection dialog only on button click?

Thanks!

Space between RadRibbonBar and acutal border

Hello,

I'm using a RadRibbonBar, which is placed inside of a Rad Pane. I've set the width of the RibbonBar to 100% because I want it to cover up the whole page, but unfortunately there still are a few pixels of blank space between the end of the RibbonBar and the border of the page. Setting padding, margin, BorderWidth or BorderStyle of any of the controls didn't change anything.
Do you have any suggestions on how to fix this?

Thanks in advance,
Robin

NodeExpand event is providing the wrong node value when using NodeTemplate

Hello!

I am using Telerik version: 2009.3.1208.0

My task is to add an arrow to the node (on the right side of the node) so people can left-click on it and access context menu. See picture attached.

I was able to to do that through creating a nodetemplate (subscribing to an interface) and then assigning my class to NodeTemplate property (on Page Init)

Here is the code:

Imports System.Web.UI

Imports System.Web.UI.WebControls

Imports Telerik.Web.UI

Public Class MyNodeTemplate

Implements ITemplate

Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

Dim newLabel As New Label()

newLabel.CssClass = "nodeLabel"

newLabel.Text = DirectCast(container, RadTreeNode).Text

Dim arrowDiv As New System.Web.UI.HtmlControls.HtmlGenericControl("DIV")

arrowDiv.Attributes.Add("class", "nodeRightClickArrow")

arrowDiv.Attributes.Add("onclick", "LeftClickContextMenuClick(event, this);")

container.Controls.Add(newLabel)

container.Controls.Add(arrowDiv)

End Sub

End Class

Everything seems fine EXCEPT:

When expanding one of the nodes, the NodeExpand Event sends the wrong value for the node that is being expanded. For example, if I expand Node 3, it gives me value (e.Node.Value) for Node 1. See attached picture for more explanation. As a result wrong child nodes are loaded.

Questions:

1) Why NodeExpand is broken when NodeTemplate is being added ?
2) Any way to achieve adding an arrow to the node so people can left-click on it without overwriting NodeTemplate?

radGrid problem after upgading to 2012.2.607.40

Hello, after upgrading from q1 2011 to the latest version, some grids began to have problems. The message is "Error en tiempo de ejecución de Microsoft JScript: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element". Debugger breaks in scriptresource.axd.

Problem appears in grids having column header titles with blank spaces as "the title", and with column filters enabled. If I remove the blanks, or disable the filters, problem dissappears.

Thanks for any help

Rad Calender Mouse Over Problem ?

Hi all,

In my project i used Rad Calender Control for display a specific dates in a different formats, eg: i want to display a national holidays in a calender with LightSkyBlue color.

For the above example i used the following code in a Webpart.

using System;

using System.ComponentModel;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using Microsoft.SharePoint;

using Microsoft.SharePoint.WebControls;

using System.Collections;

using System.Data;

using System.Drawing;

using Telerik.Web.UI;

namespace MyCalendar.MyLeaveCalender

{

[ToolboxItemAttribute(false)]

public class MyLeaveCalender : WebPart

{

private IWebPartTable _provider;

private ICollection _tableData;

private ICollection _tableData1;

protected RadCalendar CusCalender = null;

int count = 1;

//[ConnectionConsumer("Holidays")]

[ConnectionConsumer("MyLeave", AllowsMultipleConnections = true)]

//[ConnectionConsumer("Filter", "UniqueFilterName", AllowsMultipleConnections = true)]

//public void GetConnectionInterface(IWebPartParameters pProvider) { }

public void GetConnectionInterface(IWebPartTable provider)

{

TableCallback callback = new TableCallback(ReceiveTable);

_provider = provider;

provider.GetTableData(callback);

}

public MyLeaveCalender()

{

}

public void ReceiveTable(object providerTable)

{

_tableData = providerTable as ICollection;

}

protected override void CreateChildControls()

{

base.CreateChildControls();

CusCalender = new RadCalendar();

CusCalender.Width = 400;

CusCalender.Height = 200;

CusCalender.SelectedDate = DateTime.Now;

CusCalender.DayRender += new Telerik.Web.UI.Calendar.DayRenderEventHandler(CusCalender_DayRender);

Controls.Add(CusCalender);

}

protected void CusCalender_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)

{

#region Holiday Calender

if (e.Day.IsToday)

{

e.Cell.ToolTip = "ToDay";

e.Cell.BorderWidth = 2;

}

try

{

if (_tableData != null)

{

foreach (DataRowView rowView in _tableData)

{

// string widgetCode = rowView.Row[2].ToString();

string status = rowView.Row[6].ToString();

DateTime startdate = Convert.ToDateTime(rowView.Row[3].ToString());

if ((startdate.Date == e.Day.Date.Date) && (status.ToString() == "Accept"))

{

// e.Cell.BackColor = Color.LightSkyBlue;

//e.Cell.ToolTip = widgetCode;

//String url = e.SelectUrl;

e.Cell.Controls.Clear();

HyperLink link = new HyperLink();

link.Text = e.Day.Date.Day.ToString();

int j = 1;

link.ToolTip = "Leave Accepted List";

foreach (DataRowView rowView1 in _tableData)

{

DateTime startdates = Convert.ToDateTime(rowView1.Row[3].ToString());

DateTime enddate = Convert.ToDateTime(rowView1.Row[4].ToString());

string statuss = rowView1.Row[6].ToString();

if ((startdates.Date == e.Day.Date.Date) && (statuss.ToString() == "Accept"))

{

CusCalender.SelectedDates.SelectRange(startdates, enddate);

CusCalender.SelectedDayStyle.BackColor = Color.LightSkyBlue;

e.Cell.BackColor = Color.LightSkyBlue;

statuss = "";

link.ToolTip = link.ToolTip + "\n" + j + ". " + System.Text.RegularExpressions.Regex.Replace(rowView1.Row[5].ToString(), @"<(.|\n)*?>", string.Empty) + " By " + rowView1.Row[2].ToString();

j++;

}

//link.NavigateUrl = url;

e.Cell.Controls.Add(link);

Default RadGrid Images not showing even with "EnableTheming=false"

All,

I'm having a GUI issue with the RadGrid, a problem that I thought I had resolved by setting the EnableTheming to false on the RadGrid itself.

The problem is that I get blanks instead of images for any of the controls on the RadGrid that are supposed to be imaged. Originally, I got around this problem by setting 'EnableTheming=false', but as soon as I attached a Master page to the screen, the problem came back.

I tried setting the EnableTheming to false for the page and the Master Page and it still doesn't alleviate the problem. If I remove the Master Page, the images come back.

I'm wondering what else might be causing this conflict. Based on the behavior, I'm thinking it's something that might be coded on the Master page itself.

Any hints or tips would be greatly appreciated

RadFilter - Clear/Remove Filter Items programmatically

Hi,

How can I clear the filter items in the RadFilter programmatically? I want to be able to do programmatically that we can do by clicking "X" to remove a filter item from the RadFilter. Is this possible? If so, can you provide me an example to do this?

I want to remove all filter items and not just one item. (reset to the default RadFilter view with no filter expressions)

Thanks
