Can't use CTRL+F to find/highlight words (Internet Explorer)

This seems to work fine in Chrome, but not Internet Explorer 7. Any idea what might be causing this? Are there any workarounds?

Thanks!

Access values from EditItemTemplate column

Hi,

I am having issues accessing values from a Template Column that I created. Here is what I have.

....
....
  <telerik:GridTemplateColumn UniqueName="ItemDiscount" HeaderText="Discount">
   <EditItemTemplate>
   <asp:RadioButtonList ID="rdListItemDiscount" runat="server">
   <asp:ListItem Selected="True">Discount in %</asp:ListItem>
   <asp:ListItem>Discount in $</asp:ListItem>
   </asp:RadioButtonList>
    
   <telerik:RadNumericTextBox ID="txtItemDiscountVal" runat="server" Width="20px">
   </telerik:RadNumericTextBox>
   </EditItemTemplate>
   <ItemTemplate>
   <asp:Label ID="lblLineDiscountVal" runat="server" Text="No Discount Applied"></asp:Label>
   </ItemTemplate>
   </telerik:GridTemplateColumn>
   <telerik:GridEditCommandColumn UniqueName="EditCommandColumn" EditText="Add Discount"
   UpdateText="Update Discount">
   <ItemStyle CssClass="MyImageButton" />
   </telerik:GridEditCommandColumn>
.....
.....
Code Behind:

Protected Sub rgLineItems_ItemUpdated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridUpdatedEventArgs) Handles rgLineItems.ItemUpdated
   Try
   Dim i As Integer = 1
   Dim CellValue As String
   Dim txtVal As String
   CellValue = CType(rgLineItems.Items(i).FindControl("rdListItemDiscount"), RadioButtonList).SelectedItem.Value
   txtVal = CType(rgLineItems.Items(i).FindControl("txtItemDiscountVal"), TextBox).Text
   Catch ex As Exception
   End Try
   End Sub

I would like to get the selected value from the radiobuttonlist and the text value upon clicking on Update Discount. Once this is done, I would like to change the EditItemTemplate column to a value entered by the user in the textbox. Let me know where I am going wrong and is this really possible?

Thanks in advance!

Default Group Express doesn't ungroup

I'm using a RadGrid with a relatively straightforward setup of DataBound columns, and a single Grid Expression that I set on page load like this:

if (!Page.IsPostBack)

{

//set up an initial group by base

var baseExpression = new GridGroupByExpression();

var selectField = new GridGroupByField {FieldAlias = "Base", FieldName = "Dest_Name", HeaderValueSeparator = " "};

baseExpression.SelectFields.Add(selectField);

var groupField = new GridGroupByField() {FieldName = "Dest_Name"};

baseExpression.GroupByFields.Add(groupField);

Grid.MasterTableView.GroupByExpressions.Add(baseExpression);

}

I then load the data via DataSource = foo and DataBind();

The problem comes when I right click on the column header and select ungroup form the menu, it doesn't get ungrouped. I can group and ungroup with other columns, but the initial column does not ungroup, unless I use the menu to group by the column, and then ungroup it.

Is there a way around this behaviour?

Problem with grouping when applied virtual scroll paging

I have created a web page in which I placed a rad grid and set the virtual scroll paging property to true,so when I group a grid by a column in which group consumes more than 1 page so instead of showing records list in collapse manner, it shows space of records consumed by that group which should not be happened instead of this it should show records list in the collapse manner and not the space of records consumed by that group. The code for aspx page is as follows:-

<telerik:RadGrid ID="rgFITList" runat="server" AllowSorting="True"

TabIndex="3" EnableTheming="False" ShowGroupPanel="True" OnItemCommand="rgFITList_ItemCommand"

OnSortCommand="rgFITList_SortCommand" OnGroupsChanging="rgFITList_GroupsChanging"

EnableHeaderContextMenu="True" onitemdatabound="rgFITList_ItemDataBound"

GridLines="None" DataSourceID="ODS_FITList"

AllowPaging="true" PageSize="40" AllowCustomPaging="true">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="FITID"

GroupsDefaultExpanded="False" GroupLoadMode="Client" Name="Master"

DataSourceID="ODS_FITList">

<telerik:GridBoundColumn DataField="FITID" HeaderText="Task ID" SortExpression="FITID"

UniqueName="FITID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DateSubmitted" HeaderText="Submitted" SortExpression="DateSubmitted"

UniqueName="DateSubmitted" DataFormatString="{0:MM/dd/yyyy}">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ProjectName" HeaderText="Project" SortExpression="ProjectName" UniqueName="ProjectName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FITType" HeaderText="Task Type" SortExpression="FITType"

UniqueName="FITType">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FITTitle" HeaderText="Title" SortExpression="FITTitle"

UniqueName="FITTitle">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FITDescription" HeaderText="FITDescription"

UniqueName="FITDescription" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserName" HeaderText="Assigned To" SortExpression="UserName"

UniqueName="UserName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Status" HeaderText="Status" SortExpression="Status"

UniqueName="Status">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DateDue" HeaderText="Due" SortExpression="DateDue"

UniqueName="DateDue" DataFormatString="{0:MM/dd/yyyy}">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="RankID" HeaderText="RankID"

UniqueName="RankID" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Priority" UniqueName="Priority" Groupable="false">

<asp:ImageButton ID="imgMoveOrder" runat="server" CommandName="MoveOrder" ImageUrl="Images/MoveUp.gif"

ToolTip="Move Up" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn" Groupable="false">

<asp:ImageButton ID="btnRadEdit" CommandName="EditFIT" TabIndex="5" ImageUrl="~/Images/Edit.gif"

runat="server" AlternateText="Edit" />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</EditFormSettings>

</MasterTableView>

</ClientSettings>

</FilterMenu>

</telerik:RadGrid>

In order to make my problem clear, I am attaching the screenshot of the grid when grouping by a column.So please tell me solution for my problem.

Reminder Pop Up

Hi. I am using the 2009.3.1401.35 version of telerik controls and I am trying to add a reminder to the scheduler which appears that it's not supported in this version. Is there any turn around for this issue?

Thank you very much for your help.

Full class path as ASPX element tag

v2010.3.1215.35

I drop a RadAjaxManager on a form. Then I use Configure Ajax Manager to set updated controls. The result looks like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik.web.ui.ajaxsetting ajaxcontrolid="RadAjaxPanel1">

<updatedcontrols>

<telerik.web.ui.ajaxupdatedcontrol controlid="RadAjaxPanel1">

</telerik.web.ui.ajaxupdatedcontrol>

</updatedcontrols>

</telerik.web.ui.ajaxsetting>

</AjaxSettings>

</telerik:RadAjaxManager>

The expected resulting error is:

Warning Generation of designer file failed: Telerik.Web.UI.AjaxSettingsCollection must have items of type 'Telerik.Web.UI.AjaxSetting'. 'telerik.web.ui.ajaxsetting' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.

If I manually enter the markup, IntelliSense properly guides the creation of the tags to create the following:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxPanel1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

So what causes that?

I'm thinking this is just another variant on errors related to control references. With every release of RadControls and every new project I find myself frustrated with questions like the following:

Do I need a reference in web.config like this? :

<pages>

<controls>

<add tagPrefix="telerik" namespace="Telerik.Web.UI"
assembly="Telerik.Web.UI" />

</controls>

</pages>

Does that need to have the version ID?

Is it better to GAC for development or deployment?

Why is it that if I don't include a registration like the following in every user control I get errors on nested controls?

<%@ Register TagPrefix="telerik" 

             Assembly="Telerik.Web.UI, Version=2010.3.1215.35"

Namespace="Telerik.Web.UI" %>

And how do I avoid issues if I'm working on a client project that's a year old but my current system has the latest RadControls in the toolbox?

These kinds of questions and related problems have apparently affected the developer experience for many people over the years.

I'm hoping Telerik can publish a comprehensive new doc that describes the known issues and resolutions related to assembly references, page control references, nested user controls, master pages with RadAjaxManagerProxy, etc.

Thanks for your time.

foreach (CallCenterStatistics callCenterStatObj in lstCallCenterStats)

{

chartSeriesObj =

new ChartSeries();

chartSeriesObj.Type =

ChartSeriesType.Bar;

chartSeriesObj.Name = lstChars[count] +

"-" + callCenterStatObj.Description;
