Hi,

I have an error when clicking on any of the buttons in a pop up.

Here is the scenario:

I have a pop up (JQuery pop up) wuich contains a Repeater.
The Repeater has a column which contains Edit buttons.
When click on Edit button, another pop up opens.

In this pop up we have some buttons and a RadComboobx.

When we click on any of the buttons or change the combo value. I am getting the bellow error:

******************************************

Any one have any Ideas why this is happening.

Telerik.WebControls namespace

I'm getting a compiler error (cannot resolve symbol) when I try to reference the Telerik.WebControls namespace. I'm using Telerik.Web.UI file version 2011.3.115.35.

Was this code recently introduced in a newer version?

Template Columns DataBinding not hooking up

I have a grid with a number of columns. The data seems to be coming back fine from my datasource, as I have an accurate row count when paging is enabled. However, all columns are blank. When I view source, I see the markup generated by the InstantiateIn, but no data. It seems either the DataBinding event handler is not hooked up OR the grid is being defined (along with the event handlers) AFTER the data comes back and binds. I have followed the demos to the "T" and can't seem to get this to work. This is all embedded in a SharePoint visual web part. Thanks for any ideas/tips/solutions.

public class Name : ITemplate

{

#region ITemplate Members

public void InstantiateIn(Control container)

{

// open main container

container.Controls.Add(new LiteralControl("<div class=\"related-rm-eb-results-gridview-name\">"));

using (var nameLiteral = new Literal())

{

nameLiteral.ID = "Name";

nameLiteral.DataBinding += NameDataBinding;

container.Controls.Add(nameLiteral);

}

// close main container

container.Controls.Add(new LiteralControl("</div>"));

}

#endregion

public void NameDataBinding(object sender, EventArgs e)

{

using (var nameLiteral = sender as Literal)

{

if (nameLiteral != null)

{

var item = nameLiteral.NamingContainer as GridDataItem;

if (item != null)

{

var entity = item.DataItem as DataContracts.Entity;

if (entity != null)

nameLiteral.Text = entity.Name;

}

Rotated Label Alignment

Hi,

I have a Chart set up to use rotated labels on the X axis:

      chartAxis.Appearance.LabelAppearance.RotationAngle = 45;
      chartAxis.Appearance.LabelAppearance.Position.Auto = false;
      chartAxis.Appearance.LabelAppearance.Position.AlignedPosition = AlignedPositions.Top;
      chartAxis.AutoScale = false;

The result is very much like the demo that can be seen here:
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/chartandtooltip/defaultcs.aspx?product=chart

The actual x-axis labels don't line up with their corresponding points. Is there a way to shift or align the labels so the top of the text is level with the point marker for the correct point.

Regards
Liz

DateTimeColumn Null Exception

Hi I urgantly need some help
I have a RadGrid with myltiple Fields of which 2 is DateTimeColumns
I use the NeedDataSource to get data from a DataTable in the Database.
I need the EndDate Column to be able to Take nulls and Display Nulls When Returned from Database.
I can Insert Send Null Values To the Database When Inserting. But When I Need to Get The Null Date Back From The Database
I keep getting the Error: Specified cast is not valid. regarding the DateTime of EndDate.

This is my Form Code:

<telerik:RadGrid ID="rgParameters" runat="server"

AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True"

AlternatingItemStyle-BackColor="white" GridLines="None"

GroupingEnabled="False" Width="100%" Height="500px"

AutoGenerateColumns="False"

ondeletecommand="rgParameters_DeleteCommand"

oninsertcommand="rgParameters_InsertCommand"

onneeddatasource="rgParameters_NeedDataSource"

onupdatecommand="rgParameters_UpdateCommand"

oniteminserted="rgParameters_ItemInserted">

<AlternatingItemStyle BackColor="White" />

<MasterTableView Caption="Parameters"

CommandItemDisplay="TopAndBottom"

DataKeyNames="ScheduleParaID,StartDate,EndDate,WeekScheduled,WEPHScheduled"

ShowFooter="true">

<Columns>

<telerik:GridBoundColumn AllowFiltering="False" AllowSorting="False"

DataField="ScheduleParaID" HeaderText="ScheduleParaID"

ReadOnly="true" UniqueName="ScheduleParaID" Visible="False">

</telerik:GridBoundColumn>

<telerik:GridDateTimeColumn AllowFiltering="False" DataField="StartDate"

HeaderText="Start Date" UniqueName="StartDate" DataFormatString="{0:dd/MM/yyyy}">

</telerik:GridDateTimeColumn>

</telerik:GridNumericColumn>

</Columns>

<EditFormSettings EditFormType="AutoGenerated"></EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

This is my Code Behind part one.

protected void rgParameters_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

TrainOperationParameters tparam = new TrainOperationParameters();

rgParameters.DataSource = tparam.Select();

tparam = null;

}

This is my Code Behind For My DataEntity

[DataObjectMethod(DataObjectMethodType.Select, true)]

public List<TrainOperationParameters> Select()

{

List<TrainOperationParameters> list = new List<TrainOperationParameters>();

DataTable dt;

try

{

dt = DataMethods.ReturnMultipleRowResultSet("[IM].[GetTrainOpParameters]", String.Empty);

if (dt.Rows.Count > 0)

{

foreach (DataRow dr in dt.Rows)

{

TrainOperationParameters param = new TrainOperationParameters();

param.ScheduleParaID = Convert.ToInt32(dr["TrainOpParaID"]);

param.StartDate = (DateTime)dr["StartDate"];

param.EndDate = ((DateTime)dr["EndDate"]);

param.WeekScheduled = Convert.ToInt32(dr["WeekScheduled"]);

param.WEPHScheduled = Convert.ToInt32(dr["WEPHScheduled"]);

list.Add(param);

}

catch (Exception)

{

throw;

}

finally

{

dt = null;

}

return list;

}

Any Advice on why I keep Getting the Error and how I might be able to Fix it.

telerik:GridDateTimeColumn

Hello,

I have a little problem with RadGrid and 2 columns of type GridDateTimeColumn.

Extract data from the database server and bind it to the RadGrid.

There are two GridDateTimeColumn columns. I set both to have PickerType="DateTimePicker" as property. Also set EditMode="InPlace" for the RadGrid.
I put this RadGrid in aspx page which uses MasterPage. When the page loaded and I put the RadGrid into edit mode the columns look like ( before.png). When I press on the horisontal scroll in the RadGrid these two columns change there position. Please see the attached photo ( after.png). It looks like these two columns have absolute position? Any ideas how to fix that?

If I change RadGrid's property EdidMode to "PopUp" and after that change I press on RadGris's vertical scroll this problem does not exists. But I have many columns so this edit mode does not works for me.

Thanks in advance.

No Data from OData

I've got a WCF Data Service which is correctly publishing data (checked in the browser), yet when I hook it up to a RadTreeView or a RadMenu, nothing is rendered in the Browser...

My markup looks like this (generated by smart tags):

<telerik:RadODataDataSource ID="RadODataSource1" runat="server">

<Transport>

<Read Url="http://localhost:8989/ODService.svc/" DataType="XML" />

</Transport>

<Schema>

<telerik:DataModel ModelID="Thing" Set="Things">

<telerik:DataModelField FieldName="Id" />

<telerik:DataModelField FieldName="Name" />

<telerik:DataModelField FieldName="Value" />

</telerik:DataModel>

</Schema>

</telerik:RadODataDataSource>

<telerik:RadTreeView ID="RadTreeView1" Runat="server" DataFieldID="Id" DataModelID="Thing" ODataDataSourceID="RadODataSource1"></telerik:RadTreeView>

The output in the browser when directed to http://localhost:8989/ODService.svc/Things looks like this:

      </m:properties>
    </content>
  </entry>
</feed>

and finally, the source from the rendered web page where the control should be, looks like this:

<div id="RadTreeView1" class="RadTreeView RadTreeView_Clear">

<input id="RadTreeView1_ClientState" name="RadTreeView1_ClientState" type="hidden" autocomplete="off" value="{"expandedNodes":[],"collapsedNodes":[],"logEntries":[],"selectedNodes":[],"checkedNodes":[],"scrollPosition":0}">

</div>

Is there something I'm doing wrong?

I can post up the code from the data classes or the context, but the fact that the service is outputting into the browser (as above) without problems, allowing me to correctly query it, would suggest that the problem isn't in the service itself.
