RadGrid Filtering and display of Enum properties

Has anything improved with Q1 2011 on filtering of Enums ?

Unfortunately it's quite common to use eNums in C# and to need to bind objects containing enum properties to the Telerik grid.

Whilst the values display ok in the grid the filters offer integer choices only rather than a selection list of the string equivalents. Also when editing values in cells it is the integer values that are requested (unfamiliar to the users of a system).

Error 296 Metadata file '<<Project Path>>\bin\Telerik.Web.UI.dll' could not be opened -- 'Not enough storage is available to process this command. '

But I have enough memory and other process were running fine and the CPU usage is also less.

My system configuration is:
OS - Windows 2003 Server
RAM - 4 GB
Free Space in C drive - 3.09 GB

Can any one tell me why this happens and how to get rid of this?

Thanks a lot in advance.

Accessing Parent DataKeyValues from Nested Grid Insert

I have a Grid named gvModules with a nested grid called gvFields. The gvModules uses the DataKey ItemTypeID that I need when a new record is added to gvFields. I am trying to access that DataKey from the insert statement in the gvFields ItemCommand method. I've tried the examples given on the forums and in the documentation without avail. I would welcome any additional direction.

ASPX

<telerik:RadGrid ID="gvModules" runat="server" AutoGenerateColumns="False"

DataSourceID="dsModules" GridLines="None" AutoGenerateEditColumn="True"

OnItemDataBound="gvModules_OnItemDataBoundHandler"

Skin="Windows7" AllowFilteringByColumn="True" AllowSorting="True">

<MasterTableView DataKeyNames="ItemTypeID" DataSourceID="dsModules">

----

<NestedViewSettings DataSourceID="dsFields">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="ItemTypeID" MasterKeyField="ItemTypeID" />

</ParentTableRelation>

</NestedViewSettings>

<NestedViewTemplate>

<telerik:RadGrid ID="gvFields" runat="server" DataSourceID="dsFields"

AutoGenerateEditColumn="True" GridLines="None" Skin="Windows7"

OnItemDataBound="gvFields_OnItemDataBoundHandler"

OnItemCommand="gvFields_ItemCommand" OnItemUpdated="gvFields_ItemUpdated"

AllowSorting="True">

<MasterTableView CommandItemDisplay="TopAndBottom" AutoGenerateColumns="False" DataSourceID="dsFields" DataKeyNames="FieldID">

-----

</MasterTableView>

</telerik:RadGrid>

</NestedViewTemplate>

</MasterTableView>

</telerik:RadGrid>

C#

protected void gvFields_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.PerformInsertCommandName)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

//PARAM ITEM TYPE ID

GridDataItem parentItem = (GridDataItem)(e.Item.OwnerTableView.ParentItem);

if (parentItem != null)

{

string itemType = "";

itemType = parentItem.OwnerTableView.DataKeyValues[parentItem.ItemIndex]["ItemTypeID"].ToString();

lblTmp.Text += "Item Type ID = " + itemType;

//dsFields.InsertParameters["ItemTypeID"].DefaultValue = parentItem.OwnerTableView.DataKeyValues[parentItem.ItemIndex]["ItemTypeID"].ToString();

}

else

{

lblError.Text += "Cannot find parent item";

}

What I always get is 'Cannot find parent item'.

[Solved] AllowdFileExtensions ignore when RadAsyncUpload moved in DOM

Hi,

I have a situation where I need to move a RadAsyncUpload control in the DOM. After I move it the AllowedFileExtensions seems to be reset to allow all extensions. I have not been able to work out how to set the AllowedFileExtensions via javascript.

Here is the problem isolated in a simple example. Initially only jpg and wmv files can be selected. But once I click the bt_MoveDiv button and move the control in the DOM, all file types can be selected.

<body>

<form id="form1" runat="server">

<script language="javascript" type="text/javascript">

function buttonClick() {

var container = document.getElementById('container');

var ph = document.getElementById('holder');

ph.appendChild(container);

}

</script>

<div>

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

</telerik:RadScriptManager>

<div id="container">

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="jpg,wmv">

</telerik:RadAsyncUpload>

<telerik:RadProgressArea ID="RadProgressArea1" runat="server">

</telerik:RadProgressArea>

<asp:Button ID="bt_Submit" runat="server" Text="Submit" onclick="bt_Submit_Click" />

</div>

<div id="holder">

</div>

<asp:Button ID="bt_MoveDiv" runat="server" Text="Move div" OnClientClick="buttonClick();return false;" />

</div>

</form>

</body>

I had similar problems some time ago with RadEditor being moved in the DOM. This problem was fixed with the onParentNodeChanged() function. Is there something similar I can do for RadAsyncUpload?

Thanks
Andrew
