Line Break in appointment description Textarea

I'm trying to concatenate strings (table fields) via SQL SELECT statement and use the values in the

DataDescriptionField

of RadSchduler (TEXTAREA). However, I want to create line breaks between the field values.

SELECT 'Field 1: ' + field1 + ' \r\n ' + 'Field 2: ' + field2 AS ConcatString
FROM Table1

I want the appointment description (textarea) to display...

Field 1: Field1 Value
Field 2: Field2 Value

What do I use to create this? The "\r\n" didn't work. It displays as (literal) string.

I am trying to populate the Description textarea on an appointment using Telerik's RadScheduler.

<telerik:RadScheduler runat="server" ID="RadScheduler1" Width="1000px" Height="750px" SelectedDate="2011-08-01"
DayStartTime="00:00:00" DayEndTime="23:59:59" TimeZoneOffset="00:00:00" DataSourceID="SurgeryDataSource2"
DataKeyField="surID" DataDescriptionField="ConcatString" DataSubjectField="specialtyType" DataStartField="start_date" DataEndField="end_date">

Thanks.

Buttons not firing on Template EditForm in Hierarchical grid

I have a hierarchical grid containing the parent and a single child. Both forms use a templated editform. I've added custom buttons to both forms for handling insert/update/Cancel. However, on the child form, none of these seem to be firing the standard RadGrid events.

Any reason why this might be? I've checked the child grid's editform over and compared it to the parent grid's editform and can't see a problem.

Correction: Just looked deeper into it and the cancel button works. Pressing the insert button causes a response but doesn't affect the grid and doesn't store anything in the database.

SPDataSource and Telerik controls cause Visual Studio 2010 to freeze

I start a new Visual Web Part project, add an SPDataSource to any Sharepoint list, and then add a telerik control, and map the control to the datasource and VS freezes. This happens with the radlistbox, radgrid, and radlistview at a minimum. I've used RadMenu and several other controls in my Sharepoint 2010 environment without issues. Also, if I use a regular grid control and bind it to SPDataSource there's no problems.

I'm just simply adding it this way.

<SharePoint:SPDataSource ID="SPDataSource1" runat="server"
    DataSourceMode="List"
    UseInternalName="true" 
    SelectCommand="<View></View>">
    <SelectParameters>
        <asp:Parameter Name="WebUrl" DefaultValue="/subsite/" />
        <asp:Parameter Name="ListName" DefaultValue="Contacts" />
    </SelectParameters>
</SharePoint:SPDataSource>

Any ideas why this would be happening? Can you test it out?

Problem since moving to .Net 4.0

Hi,

I have recently upgraded my project to use .Net 4.0 and all seemed fine until I started trying to run some reports using Crystal which were all fine previously. I get the following error when I try to run the report and print to PDF. The message seems to indicate some issue with the Script Manager or Compression, both of which are enabled.

Any ideas why this is happening?

Page Refresh Makes One More Entry In a Database

Hi,

I am using telerik grid and editfromtemplate, and what happen is that whenever I refresh the page after inserting a record in telerik grid. It makes one more entry in the grid and in the database. I want to prevent this behaviour of grid because it's causing duplicate number of records in my grid.

Imports Telerik.Web.UI

Partial Class SNR_Config

Inherits System.Web.UI.UserControl

Private dbContext As New SNRDentonDBLayerDataContext

Protected Sub rgConfiguration_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rgConfiguration.NeedDataSource

BindGrid()

End Sub

Protected Sub BindGrid()

Dim IConfig = From Config In dbContext.SNR_Configurations Order By Config.ID Descending

Select Config

rgConfiguration.DataSource = IConfig.ToList

End Sub

Protected Sub rgConfiguration_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgConfiguration.ItemCommand

If e.CommandName = RadGrid.PerformInsertCommandName Then

Insert(e)

ElseIf e.CommandName = RadGrid.UpdateCommandName Then

Update(e)

ElseIf e.CommandName = "Delete" Then

Delete(e)

End If

End Sub

Protected Sub Insert(ByVal e As Telerik.Web.UI.GridCommandEventArgs)

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

If e.Item.OwnerTableView.IsItemInserted Then

Dim txtKey As TextBox = e.Item.FindControl("txtKey")

Dim txtValue As TextBox = e.Item.FindControl("txtValue")

Dim chkIsAdmin As CheckBox = e.Item.FindControl("chkIsAdmin")

Dim con As New SNR_Configuration

con.ConfigKey = txtKey.Text.Trim

con.ConfigValue = txtValue.Text.Trim

con.CreatedOn = DateTime.Now

con.CreatedBY = DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo.UserID

con.IsDeleted = False

con.IsAdmin = IIf(chkIsAdmin.Checked, True, False)

dbContext.SNR_Configurations.InsertOnSubmit(con)

dbContext.SubmitChanges()

End If

End Sub

Protected Sub rgConfiguration_ItemDataBound(ByVal source As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgConfiguration.ItemDataBound

If TypeOf e.Item Is GridEditableItem And e.Item.IsInEditMode Then

If TypeOf e.Item Is GridEditableItem And TypeOf e.Item Is GridEditFormInsertItem Then

Dim btnInsert As Button = e.Item.FindControl("btnInsert")

btnInsert.Visible = True

Else

Dim btnUpdate As Button = e.Item.FindControl("btnUpdate")

btnUpdate.Visible = True

End If

End Sub

End Class

Grouping Template and Bound columns

We have a RadGrid that has mostly bound columns but a few template columns. When grouping by any or all of the bound columns and then the template columns, there are no issues. However, when choosing a template column first and then a bound column, we always get the error "An error occured adding a relation to DataRelationCollection. Please, make sure you have configured the expressions properly - both GroupByFields and SelectFields are required".

javascript MasterTableView.SelectedRows = undefined

I am following this forum post:
http://www.telerik.com/community/forums/thread/b311D-mgcch.aspx

I can get the MasterTableView successfully client side, but when I do this:
var rows = $find(this._gridid).MasterTableView.SelectedRows;
rows is undefined

The grid I am using is a custom rad grid that inherits from RadGrid

    
            public class CustomRadGrid : RadGrid  
        
            {  
        
            public CustomRadGrid(){  
        
            ClientSettings.Selecting.EnableDragToSelectRows = false;  
        
            ClientSettings.Resizing.AllowColumnResize = true;  
        
            MasterTableView.AllowFilteringByColumn = false;  
        
            EnableEmbeddedSkins = false;  
        
            AllowMultiRowSelection = true;  
        
            ClientSettings.Selecting.AllowRowSelect = true;  
        
            }  
        
            }

The above snippet is just a portion of my class

Does anyone have any idea why SelectedRows would be undefined?

I originally had this posted in the older (non ajax) forum, so you may see a duplicate of this message there.

Thanks!
Nicole
