Cannot unregister UpdatePanel in Radgrid

I am creating a RadGrid as follows:

protected override void OnInit(EventArgs e)

{

this.Controls.Clear();

this._RadLoadingPanel.ID = "_RadLoadingPanel";

this._RadLoadingPanel.Transparency = 30;

this._RadLoadingPanel.Skin = "WebBlue";

this._RadLoadingPanel.BackgroundPosition = AjaxLoadingPanelBackgroundPosition.Center;

this.Controls.Add(this._RadLoadingPanel);

this._RadGrid1.Skin = "WebBlue";

this._RadGrid1.Width = Unit.Percentage(98);

this._RadGrid1.GridLines = GridLines.None;

this._RadGrid1.AutoGenerateColumns = false;

this._RadGrid1.AllowSorting = true;

this._RadGrid1.GridLines = GridLines.None;

this._RadGrid1.PageSize = 100;

this._RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;

this._RadGrid1.ShowGroupPanel = true;

this._RadGrid1.AllowPaging = true;

this._RadGrid1.AllowSorting = true;

this._RadGrid1.EnableLinqExpressions = false;

this._RadGrid1.MasterTableView.NoMasterRecordsText = string.Format("There are no documents associated with this order / quote / proposal.");

this._RadGrid1.MasterTableView.Width = Unit.Percentage(100);

this._RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

// Setup Columns

GridBoundColumn boundColumn = new GridBoundColumn();

this._RadGrid1.MasterTableView.Columns.Add(boundColumn);

boundColumn.DataField = this._DocList.DescriptionColumn.ColumnName;

boundColumn.HeaderText = "Document Type";

boundColumn.UniqueName = "DocumentType";

boundColumn.AllowSorting = true;

this._UpdatePanel.Unload += new EventHandler(UpdatePanel_Unload);

this._UpdatePanel.ID = "ajaxPanel";

this._UpdatePanel.UpdateMode = UpdatePanelUpdateMode.Always;

this._UpdatePanel.ContentTemplateContainer.Controls.Add(this._RadGrid1);

this.Controls.Add(this._UpdatePanel);

base.OnInit(e);

}

protected override void OnPreRender(EventArgs e)

{

_RadGrid1.MasterTableView.Rebind();

base.OnPreRender(e);

var ajaxManager = RadAjaxManager.GetCurrent(Page);

if (ajaxManager != null)

ajaxManager.AjaxSettings.AddAjaxSetting(this._UpdatePanel, this._RadGrid1, this._RadLoadingPanel);

}

It gives the following error:
Cannot unregister UpdatePanel with ID 'ajaxPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: updatePanel

After reading in forums I added the following:

void UpdatePanel_Unload(object sender, EventArgs e)

{

MethodInfo methodInfo = typeof(ScriptManager).GetMethods(BindingFlags.NonPublic | BindingFlags.Instance)

.Where(i => i.Name.Equals("System.Web.UI.IScriptManagerInternal.RegisterUpdatePanel")).First();

methodInfo.Invoke(ScriptManager.GetCurrent(Page),

new object[] { sender as UpdatePanel });

}

This did not resolve it. I even added this.COntrols.clear, but did not work. When I comment out the boundColumn.DataField = this._DocList.DescriptionColumn.ColumnName; statement, it displays a grid.
Please help me resolve this.

Date Picker Issue with Chrome

We are using telerik version 2011.2.915.40.

With Date Picker I am facing issue where I am getting auto populated 0nan/nan/0nan date in date picker and I have not used any Max/Min/Selected date for picker. I am getting this error only for chrome version 34.0.1847.116. It does work for other versions of Chrome and also for Safari/IE/Mozilla.

When I looked into chrome developer tools, I found error stating Invalid YEAR.

Could you please assist on this as we are end up with solutions and clients are insisting on using Chrome only.

Regards,
Dhaval Shukla

RadGrid Scrollbars Header issue

Telerik ASP.Net AJAX

Version – 2012.1.215.40

Following is the issue that we are facing while using “telerik
radgrid” control. Using scrollbars feature for the radgrid we can see the white
space highlighted in RED (image "GridViewScroll issue 1")

However we would want this white space should be equivalent to
the other column headers background. Is there any solutions with the above mentioned version of teleriks.

While going through the demo on telerik website, I have
found that this issue is not there in current version(ref below figure), can
you please ensure that this issue is resolved in latest version of telerik.
(image "GridViewScroll issue 2")

[Solved] MarkFirstMatch and what is displayed to user

I have a multi-column combobox that the user wants an ID to show in the box but be able to search on a name using the MarkFirstMatch. What I have noticed is the MarkFirstMatch works on the item.text when the databound event fires. If I set the ID to the text property then you can't search by name. If I set the name to the text property you can search by name but it will not display the ID. Is there anyway to get around this. I have tried the OnItemsRequested but the users don't like the list to get shortned, they just want the hi-light to go to the rows as they type.

telerik:RadComboBox ID="radCBTaxonomy" runat="server" AllowCustomText="true" HighlightTemplatedItems="true"

DropDownWidth="350px" Width="125px" MaxHeight="200px" OnClientKeyPressing="ChangeToUpperCase" MarkFirstMatch="true"

OnClientLoad="ChangeToUpperCase" AutoPostBack="true">

<HeaderTemplate>

<table style="width: 300px; text-align: left; font-size: 8pt">

<tr>

<td style="width: 100px;">

Taxonomy Code

</td>

<td style="width: 200px;">

Name

</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 300px; text-align: left; font-size: 8pt">

<tr>

<td style="width: 100px; text-transform: uppercase;">

<%#DataBinder.Eval(Container.DataItem, "Taxonomy")%>

</td>

<td style="width: 200px; text-transform: uppercase;">

<%# DataBinder.Eval(Container.DataItem, "ProvName")%>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

ItemDatabound event

e.Item.Text = (DirectCast(e.Item.DataItem, DataRowView))("ProvName").ToString.ToUpper()

e.Item.Value = (DirectCast(e.Item.DataItem, DataRowView))("Taxonomy").ToString.ToUpper()

Cascading dropdown with Ajax

I am implementing cascading dropdownlist . The dropdown are in the radgrid Inline Edit Mode.

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem item = e.Item as GridEditableItem;

GridEditManager manager = item.EditManager;

HyperLink hyperLink = (HyperLink)item["OrderTask"].Controls[0];

hyperLink.Visible = false;

DropDownList droplist = new DropDownList();

droplist.ID = "DropDownListOrderTask";

droplist.AutoPostBack = true;

item["OrderTask"].Controls.Add(droplist);

CascadingDropDown ccdOrderTask = new CascadingDropDown();

ccdOrderTask.ID = "ccdOrderTask";

ccdOrderTask.Category = "OrderTask";

ccdOrderTask.TargetControlID = "DropDownListOrderTask";

ccdOrderTask.PromptText = "Select Order Task";

ccdOrderTask.LoadingText = "Loading OrderTask";

ccdOrderTask.ServiceMethod = "BindOrderTask";

ccdOrderTask.ServicePath = "ajaxservice.asmx";

TextBox txt = (TextBox)item["TaskOwner"].Controls[0];

txt.Visible = false;

droplist = new DropDownList();

droplist.ID = "DropDownListTaskOwner";

item["TaskOwner"].Controls.Add(droplist);

CascadingDropDown ccdTaskOwner = new CascadingDropDown();

ccdTaskOwner.ID = "ccdTaskOwner";

ccdTaskOwner.Category = "TaskOwner";

ccdTaskOwner.ParentControlID = "DropDownListOrderTask";

ccdTaskOwner.TargetControlID = "DropDownListTaskOwner";

ccdTaskOwner.PromptText = "Select Task Owner";

ccdTaskOwner.LoadingText = "Loading Task Owner";

ccdTaskOwner.ServiceMethod = "BindTaskOwner";

ccdTaskOwner.ServicePath = "ajaxservice.asmx";

}

OnPrerender I have the following:

protected override void OnPreRender(EventArgs e)

{

base.OnPreRender(e);

var ajaxManager = RadAjaxManager.GetCurrent(Page);

if(ajaxManager != null)

ajaxManager.AjaxSettings.AddAjaxSetting(this._UpdatePanel, this._RadGrid1, this._RadLoadingPanel);

}

In the ajaxservice.asmx I have the following:

[WebMethod]

public CascadingDropDownNameValue[] BindOrderTask(string knownCategoryValues, string category)

{

OrderRequestTaskTypeTable _orderRequestTaskTypeTable = new OrderRequestTaskType_List().ExecuteTypedDataTable();

List<CascadingDropDownNameValue> orderTaskDetails = new List<CascadingDropDownNameValue>();

foreach(DataRow dtRow in _orderRequestTaskTypeTable.Rows)

{

String orderTaskId = dtRow["OrderRequestTaskTypeId"].ToString();

String orderTaskName = dtRow["DescriptionTaskType"].ToString();

//orderTaskDetails.Add(new CascadingDropDownNameValue(orderTaskId, orderTaskName));

orderTaskDetails.Add(new CascadingDropDownNameValue("orderTaskId", "orderTaskName"));

}

return orderTaskDetails.ToArray();

}

The 1st dropdown which calls BindOrderTask is empty! Am I missing something?
