How do I need to configure my RadGrid and EntityDataSource to get them to work with hierarchy? I got this to work with LinqToSql but it doesn't seem to work for me with EntityDataSource. I currently have:

<telerik:GridTableView Name="ListItems" DataKeyNames="Id, Parent.Id" DataSourceID="ListItemsDataSource" ... runat="server">
<ParentTableRelation><telerik:GridRelationFields DetailKeyField="Parent.Id" MasterKeyField="Id" /></ParentTableRelation>

<asp:EntityDataSource ID="ListItemsDataSource" ContextTypeName="Blah.Bah" EntitySetName="ListItem" Include="Parent" Where="it.Parent.Id == @ParentId" OrderBy="it.SortOrder" ... runat="server">
<WhereParameters>
<asp:Parameter Name="ParentId" Type="Int32" />
</WhereParameters>
</asp:EntityDataSource>

I'm pretty sure my problem is with the where parameter. It's not hooking into the Grid to fiter the results right. With LinqToSql the DataKeyNames and where paramenters could be identical and it worked, but with entities the DataKeys need to have a dot in them referencing the next object, and you can't put a dot in the parameter name of the where parameter used to filter the datasource. I've tried a bunch of different combinations of ParentId / Parent.Id but I can't seem to get my hierarchy to select with results filtered by the parent record.

If y'all would be kind enough to tell me what time it is or post an example of a grid with hierarchy using two EntityDataSource controls I'd be mighty appreciative. I am also using Automatic CRUD operations on these EntityDataSource controls so I don't think using a fully custom select is going to work, with LINQ I had to use Where.

Change Text Color When Button is Clicked

I'm in the process of converting all my <asp:radiobutton> and <asp:Checkbox> controls over to <telerik:radbutton> setting ButtonType="ToggleButton" and ToggleType="CheckBox" || ToggleType="Radio". We're making these updates so that the controls can be custom-styled using CSS. This is working well but we're running into just one issue. What we're struggling with is figuring out how to change the color of the checkbox text based on whether the checkbox is checked or not checked. I've turned on every optional CssClass attribute to see what's rendered in the output, but i don't see any class name changes to the <span> around the text element.

Regardless of whether the checkbox is checked or not-checked, the output HTML looks like:

<span class="rbText rbSecondary">
This is my checkbox text.
</span>

I can see that the <span> tag that contains the primary icon has a class that changes from rbToggleCheckbox to rbToggleCheckboxChecked when the checkbox is checked. How can we accomplish the samething with the text portion of the checkbox? I was really kind of expecting to see something like a SelectedCss attribute or something like some of your other controls have. I experimented with the PressedCssClass attribute but that only seems to be active for a split second while the item is being pressed. if the page loads and the checkbox is initially checked that class isn't referenced.

Any advice you have for us is greatly appreciated.
Thanks!

Load Settings with missing fields

I am building a filter string based on a list of dynamic fields and saving the filter using the SaveSettings() encoded string. I need to be able to restore this as well, however, it is possible that some of the fields in the filter are no longer available. When this is the case, LoadSettings() throws an Object reference exception at RadFilterDataFieldEditor. I would like to be able to simply invalidate the expressions that are no longer able to be part of the filter, but the exception doesn't give me any detail to work with.

Is there an alternate way of loading the expressions from the encoded string that would give me this detail?

Clientside - Find radcombo control in Header

I have been looking for a means to find a radcombo control where I know the name of the control (for example RadCombo ID =" RadComboColumn1" ) in a radGrid header... CLIENT SIDE JAVASCRIPT

Any suggestions?

function confirmCallBackFn(arg) {

if (arg == false) {

$.unblockUI();

return false;

}

$.unblockUI();

var grid = $find("<%=RadGridImport.ClientID %>");

var masterTableView = grid.get_masterTableView();

var columns = masterTableView.get_columns();

var columnCount = masterTableView.get_columns().length;

//TODO: Loop and get collection of radcombo's in headers and selected value.

var selectedColumnFields = new Array();

for (var i = 0; i < columnCount; i++) {

//TODO: Find control in radgrid hearder.

var col = columns[i]????????; var RadCombo = ????

//.get_item().findControl("columm1");

}

__doPostBack("<%= FinishButton.UniqueID %>", "");

return true;

}

While this code works on the serverside, I am needing to convert this to the clientside: var columnComboBox = headers[0].FindControl(columnName) as RadComboBox;

private List<ValueName> GetUserSelectedColumnMapping()

{

//Get the number of columns in the dynamic grid -2 hidden columns

int radGridColumnCount = RadGridImport.MasterTableView.RenderColumns.Count() - 2;

//Selected Column Type Mapping translates a dynamic column to a valid database table field.

var selectedColumnTypeMapping = new List<ValueName>();

GridItem[] headers = RadGridImport.MasterTableView.GetItems(GridItemType.Header);

for (int i = 0; i < radGridColumnCount; i++)

{

string columnName = String.Format("Column{0}", i); //Column{value} is set in the radgrid item created event.

var columnComboBox = headers[0].FindControl(columnName) as RadComboBox;

string selectedText = string.Empty;

if (columnComboBox != null)

{

var selected = columnComboBox.SelectedValue;

if (columnComboBox.SelectedItem != null)

{

selectedText = columnComboBox.SelectedItem.Text;

}

//Add the users selection to the mapping list.

selectedColumnTypeMapping.Add(new ValueName() { Name = selectedText, Value = selected, ColumnIndex = i });

}

return selectedColumnTypeMapping;

}
