Using PagerStyle NextPrevAndNumeric, when there is only one page of data displayed, the page information shows something like
"3 items in 1 pages". Since there is only one page, the text should read "3 items in 1 page". Nit-picking point, but our users would
like this to display correctly. I didn't see a way to modify this using the PagerTextFormat property - is there any way to fix this without
writing a custom pager?

Thanks.

Programmatically remove Parent Table Relations from grid

Hi

I would like to have a page where the user fills in a form which populates the grid with data. One of the options on the form would be 'show details' If this option is not ticked i would then chose not to populate the details table and not to show the expand/collapse column.

I am thinking i might be able to achieve this by programmatically removing the parent table relations from the grid in the page load event when the page is posted back but I don't know how to do this.

thanks

Need to sort a date column so that empty values appear at the bottom

Hi,

I am using a RadGrid in which I have a date column. At the moment when I sort by the column in ascending order the empty records appear at the top and then the rest of the dates are shown in ascending order.

However what I need to do is to apply a sorting algorithm so that the empty columns always appear at the bottom whether the user selects to sort in desc or asc order.

Is this possible? If so please advise the best approach in your opinion.

Thanks

Viewstate size

I have a simple RadGrid (Q2 2009) instance that does its databinding on the client side using a web service. My problem is with the amount of viewstate that the grid generates.

My grid has 8 columns. Of those, 5 are data bound columns, 2 button columns and 1 is a template column. I have tried removing these columns in various combinations but to no avail.

The grid looks to be creating about 40-50KB of viewstate on page load (before the grid calls the web service to get its data). I do not need to persist viewstate data in my current scenario.

I have tried to disable viewstate with EnableViewState=false on 1) the page 2) the user control 3) the radgrid itself. None of these seem to impact the volume of viewstate that the control generates.

RadGrid Aggregate Issue

Hey. I'm having an issue with a grid which uses a hierarchical structure along with aggregates on a column. The front end code looks like this:

                    <MasterTableView>         
               <DetailTables>         
                  <telerik:GridTableView ShowFooter="true">         
                     <ParentTableRelation>etc...</ParentTableRelation>         
                        <Columns>         
                           <telerik:GridBoundColumn HeaderText="Affiliate" DataField="affiliate"/>         
                           <telerik:GridBoundColumn HeaderText="Records Received" DataField = "RecordCount" Aggregate="Sum" UniqueName="RecordCount" DataFormatString="{0:N0}"/>         
                        </Columns>         
                        <DetailTables>         
                           <telerik:GridTableView ShowFooter="true" GridLines="None" runat="server" Name="Data" FooterStyle-ForeColor="White">         
                                   <ParentTableRelation>etc...</ParentTableRelation>         
                              <Columns>         
                                <telerik:GridBoundColumn DataField="SubID" HeaderText="SubID" UniqueName="SubID" />         
                                 <telerik:GridBoundColumn HeaderText="Record Count" DataField="Record Count" ="Record Count" DataFormatString="{0:N0}" />         
                              </Columns>         
                            </telerik:GridTableView>         
                          </DetailTables>         
                      </telerik:GridTableView>                                 
                    </DetailTables>         
                   <Columns>         
                      etc...         
                   </Columns>          
            </MasterTableView>         

The data is related properly between the nested tables. I am attempting to aggregate the Topmost "recordcount" column such that each child table displays the total count for that child in the footer. The problem is that... the footer is displaying the total count for the entire table. For example, the first child table might have 1000 records, the second 2000, and the third 3000. Each footer displays "6000" instead of 1000, 2000, and 3000. Am I doing something wrong?

Can related RadComboBoxes update more than 1 child?

I have a form I'm working on where I would like to update 2 RadComboboxes when 1 is changed.

What I'm finding is when I call requestItems() that it does it for the first child box, but not the second.

Has anyone figured out a way to do this?

Sample code is below:

    
            <%@ Page Language="VB" Trace="false" %>

Multiple Grid Client Side Paging with one Event

I have 2 grids on 1 page and I am trying to change the page of each grid in one client side event. What is happening is the last call is the only one that is performed. I have tried multiple ways of changing the page. And still get the same result. Is this a known issue and is there a workaround.

    
            TableView1 = $find("<%= TableView1.ClientID %>").get_masterTableView();  
        
            TableView2 = $find("<%= TableView2.ClientID %>").get_masterTableView();  
        
            function ChangePages(argument) {  
        
            //Method 1  
        
            TableView1.page(argument);  
        
            TableView2.page(argument);  
        
            //Method 2  
        
            TableView1.set_currentPageIndex(page);  
        
            TableView2.set_currentPageIndex(page);  
        
            }

The Controls collection cannot be modified because the control contains code blocks

Hi,

I am using Prometheus v2007.3.1314.35, and have come across this error when using the RadAjaxManager and text from our ASP.NET App_GlobalResources\Resource.resx file.

Within the Resource.resx file I have a key btnSubmit with text value "Submit".
The text is displayed within the submit button correctly, & within the UpdatePanel, but if I try to use any Resource text on the page before or after the RadAjaxManager an error is thrown.

Here is the code to replicate the error.

For the page to work remove:
(Some Text outside asp:UpdatePanel "<%= Resources.Resource.btnSubmit %>")

<

asp:ScriptManager ID=ScriptManager1 runat=server />

<p />

Some Text outside asp:UpdatePanel "<%= Resources.Resource.btnSubmit %>"

<p />

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="updPanel1">

<telerik:AjaxUpdatedControl ControlID="updPanel1" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Transparency="30" BackColor="#E0E0E0" InitialDelayTime="500">

<asp:Image ID="Image1" runat="server" ImageUrl="~/images/icons/loading.gif" BorderWidth="0px" AlternateText="Loading" ></asp:Image>

</telerik:RadAjaxLoadingPanel>

<asp:UpdatePanel ID="updPanel1" runat="server" UpdateMode=Conditional ChildrenAsTriggers=true >

<p />

<asp:Label ID=Label1 runat=server Text="Button Clicked at " />

<p />

<asp:Button ID=Button1 runat=server OnClick="Button1_Click" Text="<%$ Resources:Resource,btnSubmit %>" />

<p />

Same Text within asp:UpdatePanel "<%= Resources.Resource.btnSubmit %>"

</ContentTemplate>

</asp:UpdatePanel>

Any Ideas?
Thanks

Spacing Issue in Chrome for WCF Load On Demand Nodes

Chrome is adding extra space below nodes when loading on demand via WCF. This issue can be seen on your own demo:

http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/performance/defaultcs.aspx

Your other demos do not cause this issue, but I can't pinpoint what is causing this issue on my own version of the tree on my site using 2009.2.713.35.
