Can't add using Telerik.WebControls namespace

Hi,
I'm trying to follow a simple example using a RadGrid. Example is from RadControlsAJAXCourseWare.pdf (ch. 18), shorten the column header and provide a tooltip with the full "column header" description. Problem is that I got error message "The type or namespace name 'WebControls' does not exist in the namespace 'Telerik' (are you missing an assembly reference?)". I can't add namespace WebControls with directive 'using Telerik.WebControls;' so I must have missed something? I have added references 'Telerik.Web.UI' and 'Telerik.Web.Design'. Any kind of advice/help is highly appreciated!

Error Creating Control - Failure creating Designer

I just downloaded the latest version of your ASP.NET Controls and I am trying to use them in an existing ASP.NET Project. I get a "Error Creating Control" message for every one of the Telerik ASP.NET Controls. I have done everything listed in your help pages including registering the Telerik.Web.Design.dll in the GAC and copying it to the projects BIN directory and referencing it directly from there. Nothing is working. Please help. See attached screenshot.

Weird behave when RadDockZone exceed its height

I noticed some unspected behaviour using chrome browser when the radDockZone exceeds its fixed height, pretty much same issue same scenario found in this thread 2009 raddock issue in this same forum.

I also prepared a couple of videos demonstrating the case scenario using several browsers

IE8 working good
Chrome - not working good
Firefox working good

is this a known issue? any idea how to approach a fix for it?

BTW this issue occurs only when there's a fixed height in the raddockzone in CHROME.

thx- in advanced

Localization of RadListBox through App_LocalResource file

Hi,

I am trying to localize a RadListBox.

Here is the aspx markup:

<telerik:RadListBox ID="rlbReadOnlyGroups" runat="server" meta:resourcekey="rlbReadOnlyGroups">

</telerik:RadListBox>

Here is my resource file:

rlbReadOnlyGroups.EmptyMessage              Aucun groupe assigné

rlbReadOnlyGroups.AllToLeft                 Tous à gauche

rlbReadOnlyGroups.Localization.AllToLeft Tous à gauche

rlbReadOnlyGroups.Localization-AllToLeft Tous à gauche

As you can see, I tried to set the property "AllToLeft" by different means, but in all cases it fails to show the French translation "Tous à gauche". The EmptyMessage property is shown correctly, but all the property linked to the buttons does not work.

Anyone had this issue?

Grid dynamic column width

Hi,

I have a skeleton RadGrid on my page.

<telerik:RadGrid ID="rg" runat="server" CellPadding="2" CellSpacing="2" AutoGenerateColumns="false" EnableViewState="true"

AllowPaging="true" PageSize="25" AllowSorting="true" AllowMultiRowSelection="true" AllowCustomPaging="true"

OnNeedDataSource="rg_NeedDataSource" OnSortCommand="rg_SortCommand"

OnItemDataBound="rg_ItemDataBound">

<PagerStyle Mode="NextPrevNumericAndAdvanced" Position="Bottom" AlwaysVisible="True" />

<ClientSettings EnableRowHoverStyle="true">

<Selecting AllowRowSelect="true"></Selecting>

<ClientEvents OnRowSelected="RowSelected" OnRowDeselected="RowDeselected" />

</ClientSettings>

</telerik:RadGrid>

On the page, when user selects the columns to see then it creates the columns dynamically.

private void DesignRadGrid()

{

rg.MasterTableView.AllowMultiColumnSorting = true;

var lPropertyInfo = typeof(MyObject).GetProperties(BindingFlags.Public | BindingFlags.Instance).ToList();

var vColumns = from col in GetUserSelectedColumns() // return type is GridColumns

join pi in lPropertyInfo on col.ColumnName equals pi.Name

select new

{

col.ColumnId,

col.ColumnName,

col.DataType,

col.DisplayColumn,

col.ParentTable,

col.ParentColumn

};

var width = 0;

foreach (var oColumn in vColumns)

{

var boundColumn = new GridBoundColumn();

GridTemplateColumn templateColumn = null;

switch (oColumn.DataType)

{

case "Number":

var isUnitized = UnitSystem.CheckIfUnitized(oColumn.ParentTable, oColumn.ParentColumn);

// if isUnitized then we need template column

if (isUnitized)

{

boundColumn = null;

var unitLabel = UnitSystem.GetUnitLabel(oColumn.ParentTable, oColumn.ParentColumn, UserId);

templateColumn = new GridTemplateColumn

{

HeaderText = String.Format("{0} ({1})", oColumn.ColumnName, unitLabel)

};

hdnColumnId.Value += "," + oColumn.ColumnId;

}

break;

case "Date":

boundColumn.DtaFormatString = "{0:dd-MMM-yyyy}";

width = 75;

break;

case "Boolean"

boundColumn = null;

templateColumn = new GridTemplateColumn();

hdnColumnId.Value += "," + oColumn.ColumnId;

break;

case "Text":

if (oColumn.ColumnName.EndsWith("Remarks") || oColumn.ColumnName.EndsWith("Summary"))

width = 650;

break;

}

// For sorting to work, the columns must be added to the rg collection before defining the properties

// Telerik: Can you answer why?

if (templateColumn == null)

{

rg.MasterTableView.Columns.Add(boundColumn);

boundColumn.HeaderText = oColumn.ColumnName;

boundColumn.SortExpression = oColumn.Name;

boundColumn.DataField = oColumn.Name;

if (width > 0)

boundColumn.HeaderStyle.Width = width;

//if (width > 0)

//boundColumn.HeaderStyle.Width = Unit.Pixex(width);

}

else

{

rg.MasterTableView.Columns.Add(templateColumn);

templateColumn.HeaderText = String.IsNullOrEmpty(templateColumn.HeaderText)

? oColumn.ColumnName

: templateColumn.HeaderText;

templateColumn.SortExpression = oColumn.Name;

templateColumn.ItemTemplate = new MyTemplate(MyControlType.LiteralControl, "lit" + oColumn.ColumnId.ToString);

if (width > 0)

templateColumn.HeaderStyle.Width = width;

//if (width > 0)

//templateColumn.HeaderStyle.Width = Unit.Pixex(width);

}

var gridCheckBoxColumn = new GridClientSelectColumn { HeaderText = String.Empty, UniqueName = "Select" };

gridCheckBoxColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center;

rg.MasterTableView.Columns.Add(gridCheckBoxColumn);

var editTemplateColumn = new GridTemplateColumn();

editTemplateColumn.ItemTemplate = new MyTemplate(MyControlType.ImageButton, "ibEdit");

editTemplateColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center;

editTemplateColumn.UniqueName = "Edit";

rg.MasterTableView.Columns.Insert(0, editTemplateColumn);

}

// Class for Custom Template

public enum MyControlType

{

Button = 0,

ImageButton = 1,

LiteralControl = 2

}

public class MyTemplate : ITemplate

{

protected Control _ctrl;

private MyControlType _ctrlType;

private string _ctrlName;

public MyTemplate (MyControlType ctrlType, string ctrlName)

{

_ctrlType = ctrlType;

_ctrlName = ctrlName;

}

public void InstantiateIn(Control container)

{

switch (_ctrlType)

{

case MyControlType.Button:

_ctrl = new Button {ID = _ctrlName};

break;

case MyControlType.ImageButton:

_ctrl = new ImageButton {ID = _ctrlName};

break;

case MyControlType.LiteralControl:

_ctrl = new LiteralControl {ID = _ctrlName};

break;

}

_ctrl.EnableViewState = true;

container.Controls.Add(_ctrl);

}

I copied the above code from my VS to show only what I am trying to achieve. There might be typos or class name mistype because it is not clean copy/paste. Please ignore if any.

Anyway, my concern is that even if I define the width manually, it doesn't reflect in grid. I've tried setting width as Unit.Pixel and directly with value but both doesn't work.

Thanks.

RadComboBoxItem hide() on client-side not persisting

Hi There,

I'm busy implementing filtering of RadComboBox items from the client-side by calling the .hide() method of the combobox-item.
This results in the items I specify to be hidden from view for the user.

The problem I find is that once I click the Combo that was filtered and I click anywhere else on the html page, the items that I had set to be hidden become visible again.

Right now I think:

RadCombo is executing an event once the RadCombo is focused on (selected) and then looses focus. This event makes all the items visible again.
or I am not using the .hide() method correctly and require instructions for proper use,

Here is an extract of the relevant parts of the ASPX control and JS client-side method:

<telerik:RadComboBox ID="rcboProject" runat="server" AppendDataBoundItems="True"

DataTextField="Name" DataValueField="ClientNameProjectID" DataSourceID="objProject" MarkFirstMatch="true" AllowCustomText="true" Filter="Contains"

NoWrap="true">

<Items>

<telerik:RadComboBoxItem runat="server" Text="Non Project" Value="-1" />

</Items>

</telerik:RadComboBox>

// this function is called from client side event such as a button click or perhaps even by the

// OnClientSelectedIndexChanged event of another combo box(obviously it would need event params in that case).

function FilterProjects() {

// GetProjectCombo(index)

var projectCombo = GetProjectCombo();

// Get project combo items.

var projectItems = projectCombo.get_items();

projectCombo.trackChanges();

// loop through, hide * projects except the top 10

for (i = 0; i < projectItems._array.length; i++)

{

if (i < 10)

continue;

// Get Item, load its data.

var item = projectItems.getItem(i);

var itemValue = item.get_value();

if (true) // simplified for Telerik support.

{

item.hide(); // works temporarily until clicking on html body then it reverts back to original state.

//item.removeAt(i); // works and persists.

//item.disable(); // works and persists.

}

projectCombo.commitChanges();

}

function GetProjectCombo(index) {

return $find("<%= rcboProject.ClientID %>");

}

Additional Information:
Telerik Controls Version: 2010.1.415.40

Your help would be greatly appreciated.

Best,
Llewellyn
