Questions on UI for ASP.NET AJAX Forum

Hi,

I'm not sure if this is the right place to ask but maybe some of you might have any hints for me. I have an ajax enabled web page with a telerik RadComboBox and a VE map control on it. When I use the combo box to update the map an ajax request is performed. This request is quite slow (about 3s). First, I thought it might be a slow database connection but I found out (using System.Diagnostics.StopWatch) that the execution of the codebehind event handlers takes only 100ms while the whole ajax request takes 3s.

What could be the reason for that difference? Are there any means of improving the performance of an ajax request?

Best regards,

Robert

[Solved] set default values in web.config?

is it possible to set default values within the web.config file for specific controls?
Perhaps the direction I am headed is incorrect, but I don't see another way to deal with this other than stepping very very deep into the skin files themselves, which I don't really want to do.
for eg. It is possible to set the skin using

    
            <appSettings> 
        
                    <add key="Telerik.Skin" value="Vista" /> 
        
                 </appSettings>

but is is also possible the to default settings like AllowRowSelect for the R.A.D. grid?
ie
<add key="Telerik.Radgrid.ClientSettings.Selecting.AllowRowSelect" value="True"/>

Wondering if I am perhaps going about this wrong. I tried using a standard .skin file in my theme folder, but kept getting Unknown server Tag 'telerik:RadGrid'.

This was the skin I was attempting to use.

    
             <telerik:RadGrid Width="100%" SkinId="Postings"   runat="server"   
        
                GridLines="None"  BackColor="gold" AllowPaging="True">  
        
                    <MasterTableView  AutoGenerateColumns="False">  
        
                          <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                        <RowIndicatorColumn Visible="False">  
        
                            <HeaderStyle Width="20px" /> 
        
                        </RowIndicatorColumn> 
        
                        <ExpandCollapseColumn Resizable="False" Visible="False">  
        
                            <HeaderStyle Width="20px" /> 
        
                        </ExpandCollapseColumn> 
        
                        <EditFormSettings> 
        
                            <PopUpSettings ScrollBars="None" /> 
        
                        </EditFormSettings> 
        
                    </MasterTableView> 
        
                    <ClientSettings Selecting-AllowRowSelect="true">  
        
                    </ClientSettings> 
        
                </telerik:RadGrid>

thanks for your time and effort. the controls are really quite fantastic.

using the smart tag clutters the markup code

Hi, I have found a small (but annoying) problem with the latest version of RadGrid (2008/Q3/1125) in VS2008:

I manually added a grid to my page (in the source/markup view):

    
            <telerik:RadGrid ID="grid" runat="server" OnNeedDataSource="grid_NeedDataSource"> 
        
                <MasterTableView AutoGenerateColumns="true"> 
        
                    <ItemStyle CssClass="tr0" /> 
        
                    <AlternatingItemStyle CssClass="tr1" /> 
        
                </MasterTableView> 
        
            </telerik:RadGrid>

As soon as I switch to the design view use the smart tag (e.g. to set the AutoGenerateColums option), my markup code is changed and looks totally cluttered:

    
                    <telerik:RadGrid ID="grid" runat="server" OnNeedDataSource="grid_NeedDataSource" AutoGenerateColumns="False"  
        
                            GridLines="None">  
        
            <HeaderContextMenu EnableTheming="True"> 
        
            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
            </HeaderContextMenu> 
        
                        <MasterTableView AutoGenerateColumns="True" ShowHeader="false"> 
        
            <RowIndicatorColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </RowIndicatorColumn> 
        
            <ExpandCollapseColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </ExpandCollapseColumn> 
        
                            <ItemStyle CssClass="tr0" /> 
        
                            <AlternatingItemStyle CssClass="tr1" /> 
        
                        </MasterTableView> 
        
            <FilterMenu EnableTheming="True"> 
        
            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
            </FilterMenu> 
        
                    </telerik:RadGrid>

Can this be prevented?

Regards,
Martin

Missing client side api documentation: get_popupElement

Hi,

Seems like the get_popupElement is missing in the api documentation.
The get_element function returnes an input element which is not so obvious.
Since the get_element function doesn't return what I was expected the get_popupElement comes handy.
Hope this can help other developers too.

RadComboBox in EditFormSettings - how to find it ?

Hi

I have code :

    
            <telerik:RadGrid ID="GridAdvert" runat="server" > 
        
                     <MasterTableView DataKeyNames="id" >                        
        
                       <EditFormSettings EditFormType="Template"  > 
        
                        <EditColumn UniqueName="EditCommandColumn1">   
        
                        </EditColumn>        
        
                         <FormTemplate> 
        
                              <telerik:RadComboBox ID="findCompanyBox" runat="server" Skin="Inox"               
        
                                AllowCustomText="True" ShowToggleImage="True" ShowMoreResultsBox="true" 
        
                                EnableLoadOnDemand="True" EnableVirtualScrolling="true"   
        
                                Width="200px" Height="200px"   
        
                                ZIndex="10000" OnItemsRequested="findCompanyBox_ItemsRequested" > 
        
                                <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                              </telerik:RadComboBox>                    
        
                         <asp:Button ID="UpdateButton" OnClientClick="Save(this, event);" Text="Save"   
        
                                runat="server" /> 
        
                        </FormTemplate>                                                  
        
                       </EditFormSettings>                    
        
                      </MasterTableView> 
        
                     </telerik:RadGrid>

in code behind I have :

    
            protected void findCompanyBox_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)  
        
            {  
        
               RadComboBox findCompanyBox = new RadComboBox();  
        
               findCompanyBox = (RadComboBox)GridAdvert.FindControl("findCompanyBox");  
        
            }

After I call :
findCompanyBox = (RadComboBox)GridAdvert.FindControl("findCompanyBox");
... I get > findCompanyBox = null

My question is . How can I find RadComboBox control in Girid FormTemplate ???

Regards
Krzysztof

RadGrid popups up wrong RadWindow data.

Hello All,

I am working on a RadGrid to pull data from the database, then added a select button to popup a RadWindow to show more details of that file, it works OK. But when I filter the grid, then click on the select button it will display the wrong data for a different row like it wasn't filtered here is the aspx:

[Solved] RadComboBox paging

Hi Telerik Team,

I've use telerik for couple of weeks. My radcombobox's data is huge it's like 2000-3000 rows so when I use the arrow up and down for change the selecting item is too slow.

So I need the paging feature like gridview. Is there any way to modify Load On Demand feature to support the shown data on the number that I want.

The example is I want to show first 100 rows after user click More Result Box to load next 100 rows I need to show only next 100 rows not include first 100 rows. I need this feature because when data is bound on less number of items can be use the arrow up and down in faster than huge rows.

Thanks in advance,
-Toi
