Hierarchial Radgrid Export Issue, When Radgrid is Grouped by A particular Column

Hi,

I came accross this issue with the Hierarchial Radgrid, that when the grid data is grouped by a particular column and exported to the Excel sheet, the Child table rows are not exported properly. For all the subesquent parent rows, only the child table rows of the first parent row is repeated.

Do anyone have a solution to this issue. I am using ChildLoadMode.ServerBind before exporting.

Thanks,
Manish

radgrid bind anonymoustype

I have a rad grid that I am using the needdatasource event to populate.
I have a linq query that returns a set of information.
I refered to this link for aid: http://www.telerik.com/help/openaccess-orm/openaccess-tasks-howto-execute-query-anonimous-type.html
When I run my code I get an ugly error:
"

DataBinding: 'System.Data.Linq.SqlClient.ObjectReaderCompiler+Group`2[[<>f__AnonymousType1`4[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], TIPWebIT, Version=2010.1.415.0, Culture=neutral, PublicKeyToken=null],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' does not contain a property with the name 'ItemNumber'.

"

Here is the grid:

<telerik:RadGrid ID="RadGridInventory" runat="server" AllowPaging="True" AllowSorting="True"

GridLines="None" OnNeedDataSource="RadGridInventory_NeedDataSource"

AutoGenerateColumns="False">

<MasterTableView CommandItemDisplay="None">

<CommandItemSettings ExportToPdfText="Export to Pdf" />

<Columns>

<telerik:GridTemplateColumn DataField="ItemNumber" HeaderText="Product Number" SortExpression="ItemNumber"

UniqueName="ItemNumber">

<ItemTemplate>

<asp:Label ID="ItemNumberLabel" runat="server" SkinID="EditForms" Text='<%# Eval("ItemNumber") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="ItemName" HeaderText="Product" SortExpression="ItemName"

UniqueName="ItemName">

<ItemTemplate>

<asp:Label ID="ItemNameLabel" runat="server" SkinID="EditForms" Text='<%# Eval("ItemName") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Here is the linq to sql statement that is used to populate the grid:

protected void RadGridInventory_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{

TIPWebITLibrary.DAL.TIPWebITDataContext DC = new TIPWebITLibrary.DAL.TIPWebITDataContext();

var RoomInventory = (from items in DC.tblTechItems

join inventory in DC.tblTechInventories on items.ItemUID equals inventory.ItemUID

where inventory.EntityTypeUID == 2 && inventory.EntityUID == Convert.ToInt32(HiddenFieldEntity.Value)

group items.ItemNumber by

new { items.ItemNumber, items.ItemName, inventory.EntityTypeUID, inventory.EntityUID } into g

select g);

this.RadGridInventory.DataSource = RoomInventory.ToList();

}

Any ideas on what I am doing wrong here?

Here is the result set when I run my linq statement in LinqPAD:

Key=

{ ItemNumber = 1251341, ItemName = C510 Webcam, EntityTypeUID = 2, EntityUID = 1 }
ItemNumber	1251341
ItemName	C510 Webcam
EntityTypeUID	2
EntityUID	1

1251341

Key=

{ ItemNumber = 1251343, ItemName = MacBook, EntityTypeUID = 2, EntityUID = 1 }
ItemNumber	1251343
ItemName	MacBook
EntityTypeUID	2
EntityUID	1

1251343

Define custom format option behaviour?

Hi!
Is there any way to make custom configurations of formatting options in the toolbar?
For example, I would like the existing "Heading 2" (or a completely custom item) cause "Selected text" to be replaced with "<h2><span>Selected text</span></h2>" instead of just "<h2>Selected text</h2>".

Any input on this is appreciated.

/Dan

Ajax not working after upgrade 2010.2.929.35

I upgraded a project to the latest version 2010.2.929.35 and I had Radcombobox that when changed updated a grid with a Linqdatasource but now changing the combobox won't refresh the grid. any thoughts on what may have happened?

this is in my masterpage

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

<asp:ScriptReference Path="Scripts/SessionKeepalive.js" />

</Scripts>

</telerik:RadScriptManager>

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

</telerik:RadAjaxManager>

this is the combobox

<telerik:RadComboBox ID="_Stage" runat="server" AutoPostBack="True"

onselectedindexchanged="_Stage_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem runat="server" Text="Pre-Proposal" Value="Pre-Proposal" />

<telerik:RadComboBoxItem runat="server" Text="Proposal" Value="Proposal" />

<telerik:RadComboBoxItem runat="server" Text="Active" Value="Active" />

</Items>

</telerik:RadComboBox>

grid header

<telerik:RadGrid ID="_opps" runat="server" DataSourceID="LinqDataSource1"

GridLines="None" AllowFilteringByColumn="True" AllowSorting="True"

Width="1600px" onitemdatabound="_opps_ItemDataBound"

onexcelmlexportrowcreated="RadGrid1_ExcelMLExportRowCreated"

onexcelmlexportstylescreated="RadGrid1_ExcelMLExportStylesCreated"

onitemcommand="_opps_ItemCommand"

onitemcreated="_opps_ItemCreated" >

<ExportSettings ExportOnlyData="True" IgnorePaging="True"

OpenInNewWindow="True">

<Excel Format="ExcelML" />

</ExportSettings>

<MasterTableView AutoGenerateColumns="False" DataSourceID="LinqDataSource1"

DataKeyNames="OPPORTUNITYID" UseAllDataFields="True">

LinqDatasource where parameters

<WhereParameters>

<asp:ControlParameter ControlID="_Stage" Name="STAGE"

PropertyName="SelectedValue" Type="String" />

<asp:ControlParameter ControlID="_Type" Name="TYPE"

PropertyName="SelectedValue" Type="String" />

</WhereParameters>

I setup the ajax using

private object Content(string id)

{

return Page.Master.FindControl(id);

}

protected void Page_Load(object sender, EventArgs e)

{

AjaxManager.AjaxSettings.AddAjaxSetting(_opps, _opps);

AjaxManager.AjaxSettings.AddAjaxSetting(_opps, _number);

}

radfilter fieldname error

I am trying to get RadFilter to work.

I am building a DNN module with OpenAccess.

I have a basic RadGrid already on the page. I added RadFilter and set the FilterContainer to point to my grid. I also defined 2 simple fields to filter.

I keep getting this error though at runtime:

Disable Hover Highlight On RadToolBarButton

Hi

I have a radToolbar using the Office2007 skin. When hovering over the buttons a orange highlight appears. For 1 of the buttons in my toolbar I dont want the orange background.

My button is as follows :

<telerik:RadToolBarButton commandName="status" HoveredCssClass="noHover" tooltip="Initial page state" PostBack="false" ImageUrl="/status_alert.png" />

I have CSS as follows :
<style>
.noHover {
background-image:none !important;
}
</style>

When viewed in browser the .noHover style is applied to my button but the orange background still appears. How do i stop the orange hightlight appearing ?

Thanks in advance

RadGrid and RadAjaxManager issue

I have a web application that uses a master page and content pages. On several of the pages I am using the RadGrid Control and the RadAjaxManagerProxy control (the RadAjaxManager is on the master page). On one page in particular when the user clicks the form (html form tag) it triggers an event handler that causes a javascript error - "Microsoft JScript runtime error: Object doesn't support this property or method" - and calls the javascript function

Sys$WebForms$PageRequestManager$_matchesParentIDInList.

function

Sys$WebForms$PageRequestManager$_matchesParentIDInList(clientID, parentIDList) {

for (var i = 0, l = parentIDList.length; i < l; i++) {

if (clientID.startsWith(parentIDList[i] + "_")) {

return true;

}

return false;

}

On this page I have 3 RadGrids and if I remove the one with the following code evrything works fine.

<

telerik:RadGrid ID="gvExpenseAssignments" runat="server" AutoGenerateColumns="false" Height="570">

<MasterTableView DataKeyNames="GL_Account_Template_Id" EditMode="InPlace" AllowMultiColumnSorting="false"

TableLayout="Fixed" AllowNaturalSort="false" Width="99%">

<telerik:GridBoundColumn DataField="ItemsString" Visible="false" UniqueName="strHintItems"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="GL_Account_Name" HeaderText="Account Name" ReadOnly="true" AllowSorting="true" HeaderStyle-Width="260"></telerik:GridBoundColumn>

<telerik:GridButtonColumn Text="Hint" runat="server" CommandName="cmdHint" HeaderText="Account Items" ShowInEditForm="true" HeaderStyle-Width="65px" ItemStyle-Width="65px"></telerik:GridButtonColumn>

<telerik:GridButtonColumn Text="Suggest" runat="server" CommandName="cmdSuggest" HeaderText="Mapping Assistant" ShowInEditForm="true" HeaderStyle-Width="65px" ItemStyle-Width="65px"></telerik:GridButtonColumn>

<telerik:GridBoundColumn DataField="GL_Account_No" HeaderText="Linked Account No" UniqueName="lblAcctNo" ReadOnly="true" AllowSorting="true"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Cust_GL_Account_Name" HeaderText="Linked Account Name" UniqueName="lblAcctName" ReadOnly="true" AllowSorting="true"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

The whole aspx file is attached as an image file. I get the same behavior wether I data bind the grid or not. The issue that I have found is that clientID in the javascript function is a function and not a string so it contains no method startsWith. I have found a workaround that creates an anonomous function for startsWith -

Function.prototype.startsWith = function(){return false;};

but I would like to be able to find a mor permanent fix or what I am doing that is causing the error to begin with.

Thank you.
