[Solved] Sorting/Filtering on Child Classes

I have a RadGrid that's binding to a list of abstract classes. However, some properties of some of the child classes have to be exposed in the grid (and left blank if they don't exist):

<telerik:RadGrid runat="server" ID="rgStuff" AllowSorting="true" AllowFilteringByColumn="true" OnNeedDataSource="rgStuff_NeedDataSource" AutoGenerateColumns="False">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="Generic1" DataField="Generic1"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Generic2" DataField="Generic2"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Bob1" DataField="Bob1"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Bob2" DataField="Bob2"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Steve1" DataField="Steve1"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Steve2" DataField="Steve2"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Class definitions and binding code:

class Generic

{

public string Generic1 { get; set; }

public string Generic2 { get; set; }

}

class Bob : Generic

{

public string Bob1 { get; set; }

public string Bob2 { get; set; }

}

class Steve : Generic

{

public string Steve1 { get; set; }

public string Steve2 { get; set; }

}

public partial class InheritanceTest : System.Web.UI.Page

{

protected void rgStuff_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

rgStuff.DataSource = new List<Generic>() {

new Bob() { Generic1 = "First", Generic2 = "Bob", Bob1 = "Bob1-1", Bob2 = "Bob1-2" },

new Bob() { Generic1 = "Second", Generic2 = "Bob", Bob1 = "Bob2-1", Bob2 = "Bob2-2" },

new Steve() { Generic1 = "First", Generic2 = "Steve", Steve1 = "Steve1-1", Steve2 = "Steve1-2" },

new Steve() { Generic1 = "Second", Generic2 = "Steve", Steve1 = "Steve2-1", Steve2 = "Steve2-2" }

};

}

Display of the grid works great. However, when I attempt to filter or sort on a column that exists in one of the child classes, I get an error:

No property or field 'Bob1' exists in type 'Generic'

Is there a simple way to go about fixing this? I have a few workarounds in mind (creating a view of the data and binding to that, or adding virtual properties to the Generic class), but I'd rather do this as cleanly and with as little overhead as possible.

Thanks!

Linking to anchor in radwin scrolls parent page

Can anyone tell me how to stop the behavior of the parent page scrolling down until the radwindow is at the top of the page when linking to an anchor tag within the radwindow content? I originally thought it was due to my href being "#", but I changed it to "javscript:void(0);" and the same thing happens.

Selection out of range Parameter name: value

Hi

I am going round in circles trying to beat this problem which I fairly sure is a result trying bind the value of the combos box item to a column which may contain null value. The error occurs as soon as the the grid's 'Edit' button is clicked with some database items/

The relevant grid declaration is like this

<telerik:GridTemplateColumn DataField="Marshals" HeaderText="Marshal"

SortExpression="Marshals" UniqueName="Marshals" Visible="False">

<EditItemTemplate>

<telerik:RadComboBox ID="RadComboBox1" Runat="server"

AppendDataBoundItems="True" SelectedValue='<%# bind("Marshals") %>'

Width="225px">

</telerik:RadComboBox>

</EditItemTemplate>

<ItemTemplate>

<asp:Label ID="MarshalsLabel" runat="server" Text='<%# Eval("Marshals") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

And the code behind builds a dataset and binds to the combo

Protected Sub RadGrid1_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then

Dim editform As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

Dim combo As RadComboBox = DirectCast(editform.FindControl("RadComboBox1"), RadComboBox)

Bind(combo)

Dim combo2 As RadComboBox = DirectCast(editform.FindControl("RadComboBox2"), RadComboBox)

Bind(combo2)

End If

End Sub

Private Sub Bind(combo As RadComboBox)

Dim strMemberID As String = ""

Dim sb As New StringBuilder

Dim Ds As New DataSet

Dim UserTable As New DataTable("UserTable")

UserTable.Columns.Add("Text", GetType(String))

UserTable.Columns.Add("Value", GetType(String))

UserTable.Rows.Add("Pick one", "0")

Dim rdr As SqlDataReader = ConstClass.getCurrentMembers()

If rdr.HasRows Then

While rdr.Read()

' build a row of the combo

' Text

If Not IsDBNull(rdr("FirstName")) Then

sb.Append(rdr("FirstName"))

Else

sb.Append("")

End If

sb.Append(" ")

If Not IsDBNull(rdr("LastName")) Then

sb.Append(rdr("LastName"))

Else

sb.Append("")

End If

sb.Append(" & ")

If Not IsDBNull(rdr("PartnerFirstName")) Then

sb.Append(rdr("PartnerFirstName"))

Else

sb.Append("")

End If

sb.Append(" ")

If Not IsDBNull(rdr("PartnerLastName")) Then

sb.Append(rdr("PartnerLastName"))

Else

sb.Append("")

End If

If Not IsDBNull("MemberID") Then

strMemberID = rdr("MemberID")

Else

strMemberID = "0"

End If

UserTable.Rows.Add(sb.ToString, strMemberID)

sb.Clear()

End While

UserTable.AcceptChanges()

Ds.Tables.Add(UserTable)

Ds.AcceptChanges()

rdr.Close()

LiteralTest.Text = sb.ToString

Else

UserTable.Rows.Add(sb.ToString, strMemberID)

UserTable.AcceptChanges()

Ds.Tables.Add(UserTable)

Ds.AcceptChanges()

rdr.Close()

End If

combo.DataTextField = "Text"

combo.DataValueField = "Value"

combo.DataSource = Ds

End Sub

This all works just fine until when you try to edit an item that has a Null value for 'Marshals' (which is an integer) in the record.
How do I escape? I have tried several of the solutions in this forum that seem as if they might be my case but to no avail so far.

BTW I am using Q2 2010 on this website.

Thanks

Use a column to open email

What I have is a radgrid with one column we are binding a persons email to it so that someone can click on the column and open outlook and then email someone. But what happens is that it actually forwards the page and errors out, it still opens outlook but errors out the page. Tired with a hyperlink and then tried seperately with a a href, both act the same way in forwarding the page to the persons email which errors it out.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"

OnUpdateCommand="RadGrid1_UpdateCommand">

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:HyperLink NavigateUrl='<%# Bind("Name", "mailto:{0}") %>' Text='<%# Bind("Name") %>'

runat="server" ID="hlEmail"></asp:HyperLink>

<br />

<a href='<%# "mailto:" + Eval("Name") %>'><%# Eval("Name") %></a>

</ItemTemplate>

</telerik:GridTemplateColumn>
