Custom Task Field is Not Showing up in the TreeView

Hello,

I have added One Custom Task Field 'SrNo' as object datatype with respect to demo project given here. I have not used EntityFramework. I am Binding RadGantt's Datasource and DependenciesDataSource simply on Page_Load Event.

To add new Task Field below is the code I have written

public class CustomGanttTaskFactory : ITaskFactory

{

Task ITaskFactory.CreateTask()

{

return new CustomTask();

}

public class CustomTask : Task

{

public CustomTask()

: base()

{

}

public object SrNo

{

get { return (object)(ViewState["SrNo"] ?? ""); }

set { ViewState["SrNo"] = value; }

}

protected override IDictionary<string, object> GetSerializationData()

{

var dict = base.GetSerializationData();

dict["SrNo"] = SrNo;

return dict;

}

public override void LoadFromDictionary(System.Collections.IDictionary values)

{

base.LoadFromDictionary(values);

SrNo = values["SrNo"];

}

Page_Load Event:

protected void Page_Load(object sender, EventArgs e)

{

List<ITask> newFinalTask = new List<ITask>();

List<IDependency> FinalDependency = new List<IDependency>();

newFinalTask.Add(new CustomTask { ID = 1, SrNo = "1", OrderID = 1, ParentID = null, Title = "A", Start = new DateTime(2015, 01, 10, 0, 0, 0), End = new DateTime(2015, 01, 19, 23, 59, 59), PercentComplete = 0.60M, Expanded = false, Summary = true });

newFinalTask.Add(new CustomTask { ID = 2, SrNo = "", OrderID = 2, ParentID = 1, Title = "A1", Start = new DateTime(2015, 01, 10, 0, 0, 0), End = new DateTime(2015, 01, 15, 23, 59, 59), PercentComplete = 0.60M, Expanded = false });

newFinalTask.Add(new CustomTask { ID = 3, SrNo = "", OrderID = 3, ParentID = 1, Title = "A2", Start = new DateTime(2015, 01, 16, 0, 0, 0), End = new DateTime(2015, 01, 19, 23, 59, 59), PercentComplete = 0.60M, Expanded = false });

newFinalTask.Add(new CustomTask { ID = 4, SrNo = "2", OrderID = 4, ParentID = null, Title = "B", Start = new DateTime(2015, 01, 20, 0, 0, 0), End = new DateTime(2015, 01, 31, 23, 59, 59), PercentComplete = 0.60M, Expanded = false, Summary = true });

newFinalTask.Add(new CustomTask { ID = 5, SrNo = "", OrderID = 5, ParentID = 4, Title = "B1", Start = new DateTime(2015, 01, 20, 0, 0, 0), End = new DateTime(2015, 01, 31, 23, 59, 59), PercentComplete = 0.60M, Expanded = false });

FinalDependency.Add(new Dependency { ID = 1, PredecessorID = 1 ,SuccessorID = 4, Type = DependencyType.FinishStart });

RadGantt1.DataSource = newFinalTask;

RadGantt1.DependenciesDataSource = FinalDependency;

}

Design Page:

<telerik:RadGantt runat="server" ID="RadGantt1"

Enabled="true"

ReadOnly="True"

AllowSorting="False">

<DataBindings>

<TasksDataBindings IdField="ID" TitleField="Title" StartField="Start" EndField="End"

<telerik:GanttBoundColumn DataField="Start" HeaderText="START" DataFormatString="dd/MM/yyyy" AllowEdit="false" AllowSorting="false" Width="80px"></telerik:GanttBoundColumn>

<telerik:GanttBoundColumn DataField="End" HeaderText="END" DataFormatString="dd/MM/yyyy" AllowEdit="false" AllowSorting="false" Width="80px"></telerik:GanttBoundColumn>

<telerik:GanttBoundColumn DataField="PercentComplete" HeaderText="% COMPLETED" AllowEdit="false" AllowSorting="false"></telerik:GanttBoundColumn>

</Columns>

</telerik:RadGantt>

But it is not Displaying Data in Sr.No. Field. Below Attached is the output Image.

Please help me with what is wrong with my code.

RadGrid Paging

Hi,

I am trying to implement paging on a RadGrid in a web forms application.

The problem I am having is that when the user selects a page the correct information displays, but then the text '22057|updatePanel|ctl00_MainContent_ctl00_MainContent_grdResultsPanel|'

erroneously appears above the control after which the paging no longer functions. I have attached part of a screenshot so you can see what I'm talking about.

Why is this happening?

ASPX:

<telerik:RadGrid ID="grdResults" runat="server" Width="100%" Height="430px" PageSize="10"

ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left"

OnItemCommand="grdResults_ItemCommand" OnItemDataBound="grdResults_ItemDataBound"

AllowPaging="True"

AlternatingItemStyle-HorizontalAlign="Left" ItemStyle-BackColor="#ffffff"

AlternatingItemStyle-BackColor="#eeeeee" Visible="true"

AutoGenerateColumns="false"

OnNeedDataSource="grdResults_NeedDataSource">

<MasterTableView TableLayout="Auto">

<NoRecordsTemplate>

<div style="padding: 8px 0 5px 5px; height: 20px; width: 110%;">

There are currently no candidates that match the selection.

</div>

</NoRecordsTemplate>

<Columns>

<telerik:GridTemplateColumn HeaderText="Candidate ID" UniqueName="CandidateID" Visible="false">

<ItemTemplate>

<%#Eval("CandidateID")%>

</ItemTemplate>
