Hello,
I'm trying to databind RadGrid control using method provided on this page:

http://www.telerik.com/help/aspnet-ajax/mvc-radgrid-databinding.html

    
            <% 
        
               RadGrid1.DataSource = ViewData["Customers"]; 
        
               RadGrid1.DataBind(); 
        
            %> 
        
            <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="false"> 
        
            ....

but when I try to run it I'm getting this error:

    
            Script controls may not be registered after PreRender. 
        
            Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
        
            Exception Details: System.InvalidOperationException: Script controls may not be registered after PreRender.

on the line with .....DataBind();

[Solved] Setting TimeView of RadDateTimePicker in RadGrid

I would like to set the TimeView's StartTime and EndTime once the control has it's value. The RadDateTimePicker exists within the EditTemplate of a RadGrid. I tried handling the ItemDataBoundEvent of the RadGrid, finding the RadDateTimePicker and then setting it's TimeView values. This does not seem to work. I'm guessing that it's too late in the process. I need to be able to access the server side (run a query) to know what values to set based on the date selected in the RadDateTimePicker. Ideas?

Programmatically set scroll position on Master/Child grid?

I found the articles posted on how to set scroll position client-side for a grid, but it doesn't work for my purpose. I have a master/child grid where I am expanding the selected child, then selecting the row with the data from code. I've implemented a search form on a tab that switches to the main master/child tab with the data, expands the correct child entry, selects it, then fires two more grids that are related.

All of my code works except that I can't move the child grid positions. This is annoying since I'm using it for a medical provider directory. A single expansion can span about 4 screens. If I could pull the scroll into position it would really help the interface and user experience.

A text example of what I'm discussing:

MASTER GRID
CHILD-A
CHILD-B
CHILD-C
ETC.

Figure the child records go to ZZZZ. I have the key to my desired row, how do I move the scroll bar to this record?

Thanks!

RadEditor1.Content

Hi,
I am trying to get the length of the text that I have entered in the RAD Editor. While the character count box at the bottom of the editor gives the correct count(which uses js: editor.get_html), the function in which I use "RadEditor1.Content" to return the count, seems to be adding the enter characters in the text and hence there seems to be a mismatch between the actual character count shown at the bottom and the one the code is checking against -for validation. Am I missing something here. Your input is highly appreciated. Thanks.

[Solved] Export Excel with Updated Column Value

Hi,
I'm trying to export a grouped grid to excel. Only one issue left...

In RadGrid1_ItemDataBound I change the value of a column "totalseconds" from a number (92) to a string (1:32). Basically I'm converting seconds to a minute string. When I export to Excel, the column "totalseconds" spits out a bunch of zeros, instead of the updated value. The zeroes are not even the correct "original" values.

I think the question is... how do I maintain the updated value, from ItemDataBound, when exporting to Excel? I tried changing the value in ItemCreated and PreRender, but that didn't seem to work either. I have also tried everything in "Exporting Tips and Tricks" to no avail.

Here's the relevant code:

    
            <telerik:radgrid AllowSorting="true" AutoGenerateColumns="false" AllowFilteringByColumn="False" 
        
                        AllowPaging="true" PageSize="20" id="RadGrid1" Skin="Gray" runat="server" OnExcelExportCellFormatting="RadGrid1_ExcelExportCellFormatting">  
        
                        <MasterTableView> 
        
                           <GroupByExpressions> 
        
                             <telerik:GridGroupByExpression> 
        
                               <SelectFields> 
        
                                   <telerik:GridGroupByField FieldAlias="Activity" FieldName="daterounded" FormatString="{0:D}" HeaderValueSeparator=" from date: "></telerik:GridGroupByField> 
        
                               </SelectFields> 
        
                               <GroupByFields> 
        
                                   <telerik:GridGroupByField FieldName="daterounded" SortOrder="Descending"></telerik:GridGroupByField> 
        
                               </GroupByFields> 
        
                             </telerik:GridGroupByExpression>

                                <telerik:GridBoundColumn DataField="status" UniqueName="status" HeaderText="Lesson Status" /> 
        
                                <telerik:GridBoundColumn DataField="totalseconds" UniqueName="totalseconds" HeaderText="Total Time" /> 
        
                            </Columns> 
        
                        </MasterTableView> 
        
            </telerik:radgrid>

    
            Private Sub RadGrid1_NeedDataSource(ByVal [source] As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs)_ Handles RadGrid1.NeedDataSource

                    RadGrid1.ExportSettings.OpenInNewWindow = True 
        
                    RadGrid1.MasterTableView.ExportToExcel()  
        
            End Sub

Any ideas?
Thanks,
Joe

Possible Bug with MonthView-AdaptiveRowHeight="True"

Telerik - you rock. I've been digging Telerik for about 5 years now and must say "thank you" for the quality controls!

When using the RadScheduler, I've noticed a small bug. If I set MonthView-AdaptiveRowHeight="True", and have a row on the calendar with now events, I am unable to drag & drop events from other rows to that row. I can drag them to rows that contain events, but cannot drag them to rows without events.

Make sense?

For now, I'm just not using AdaptiveRowHeight, but wanted to report this to see if anyone else can replicate the behavior.

Take care,

MJ

Map OnServerClick Bug

Hi,

I have a <ve:Map....> control on my page and it works fine. I am using its, onserverclick, onserverfind, and onclientclick handlers. Here is the code for the control.

ve:Map ID="vemapDealerLocator" runat="server" Height="491px" Width="491px" ZoomLevel="2"
OnServerClick="vemapDealerLocator_ServerClick" OnServerFind="vemapDealerLocator_ServerFind"
OnClientClick="ClientClick" Center-Longitude="0" Center-Latitude="0" DashboardSize="Small" />

Now when I click on the map the onserverclick goes back to the server and calls the appropriate function in both the IE and Google Chrome browsers, but for some reason when I try it in Firefox the following exception is thrown:

[Exception... "'Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: 281.79998779296875 is not a valid value for Int32.' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "JS frame :: chrome://firebug/content/spy.js :: onHTTPSpyReadyStateChange :: line 497" data: no]

mapcontrol.ashx?v=6.1()()mapcontr...shx?v=6.1 (line 126)

;this.CreditsFor=function(a,i,j,h){var e...efined")closeDependency("mapcontrol.js")

Can you please tell me the reason for this error?

Thanks,
Monzer
