Using list of Dictionary as datasource for DetailTableViews?

In a telerik:RadGrid, I specify that every line will have a detail table:

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

OnDetailTableDataBind="grd_OnDetailTableDataBind" AllowMultiRowSelection="True">

<MasterTableView DataKeyNames="id1,id2">

<Columns>

<telerik:GridClientSelectColumn UniqueName="DetailCheckColumn"/>

<telerik:GridBoundColumn HeaderText="Date" DataField="foo"/>

<telerik:GridBoundColumn HeaderText="Time" DataField="bar"/>

<telerik:GridBoundColumn HeaderText="Activity" DataField="xod"/>

</Columns>

<DetailTables>

<telerik:GridTableView ShowHeadersWhenNoRecords="True"

DataKeyNames="id" Name="Child"/>

</DetailTables>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

In the handler for the OnDetailTableDataBind event, I specify the data source for the DetailTableView. The handler is called when a line is expanded. Setting a list of anonymous objects as data source works fine, but a list of Dictionary will not.

I get a yellow page, It seems like the grid table view tries to find a property id of Dictionary

DataBinding: System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] does not have a property with the name id.

If I remove the DataKeyNames attribute in the detail table, I will get a detail table with the correct number of lines, but the fields will be all blank (screenshot is attached).

The event handler where I create the detail table for each expanded line. Observe that I name columns c1, c2 etc. I create the columns in the first loop round.

protected void grd_OnDetailTableDataBind(object sender,

GridDetailTableDataBindEventArgs e)

{

var tv = e.DetailTableView;

var parentItem = e.DetailTableView.ParentItem;

var bis = dal.get_booking_informations();

tv.Columns.Add(new GridClientSelectColumn());

var columnNameDict = new Dictionary<string,string>();

var firstDict = true;

var dicts = bis.GroupBy(bi=>bi.platsBokadID).Select(group =>

{

var dict = new Dictionary<string, string>();

dict["id"] = "" + group.Key;

var list = group.ToList();

if (firstDict)

{

firstDict = false;

var num = 0;

var columns = list.Select(header=>

{

var shortName = "c" + ++num;

columnNameDict[header.HeaderName] = shortName;

return new GridBoundColumn

{

DataField = shortName,

HeaderText = header.HeaderName

};

});

foreach(var column in columns)

tv.Columns.Add(column);

}

foreach(var header in list)

{

var shortName = columnNameDict[header.HeaderName];

dict[shortName] = header.Value;

}

return dict;

});

tv.DataSource = dicts;

}

I have also tried to use dynamic objects instead of Dictionaries (with the same result):

protected void grdActivitiesToCopy_OnDetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

var tv = e.DetailTableView;

var parentItem = e.DetailTableView.ParentItem;

var bis = dal.get_booking_informations();

tv.Columns.Add(new GridClientSelectColumn());

var columnNameDict = new Dictionary<string,string>();

var firstDict = true;

var dicts = bis.GroupBy(bi=>bi.platsBokadID).Select(group =>

{

var dict = new Dictionary<string, object>();

dict["id"] = "" + group.Key;

var list = group.ToList();

if (firstDict)

{

firstDict = false;

var num = 0;

var columns = list.Select(header=>

{

var shortName = "c" + ++num;

columnNameDict[header.HeaderName] = shortName;

return new GridBoundColumn

{

DataField = shortName,

HeaderText = header.HeaderName

};

});

foreach(var column in columns)

tv.Columns.Add(column);

}

var eo = new ExpandoObject();

var eoColl = (ICollection<KeyValuePair<string, object>>)eo;

foreach(var header in list)

{

var shortName = columnNameDict[header.HeaderName];

dict[shortName] = header.Value;

}

foreach (var kvp in dict)

{

eoColl.Add(kvp);

}

dynamic eoDynamic = eo;

return eoDynamic;

}).ToList();

tv.DataSource = dicts;

}

Hide expand-collapse column under images

Hi,

I've read as many of the posts on this topic as I can but just can't get it to work for me.

Please the attached image - I want to get rid of the grey area and move the details rows left, underneath the expand-collapse icons.

Thanks in advance,

Jack

WAI-ARIA: Suggestion: Add property to change role

Currently, the RadPanelBar can only act as a tab strip (role="tabstrip"). (Actually, the current implementation is missing the role="tabstrip" attribute, so it's basically invalid and only a collection of incoherent tabs.)

The RadPanelBar, however, is rather a menu. It may, semantically, even rather be a tree view, too.

It depends on the usage on a web page what the RadPanelBar is actually supposed to represent.

So I suggest to add an enumeration property to the RadPanelBar enabling developers to designate it either

as a tabstrip (containing tabs)
as a menu (containing menu items)
as a tree view (containing tree items)

Regards,
Axel
