Questions on UI for ASP.NET AJAX Forum

I have a grid and in the grid I have a template column which is an asp checkbox called "Purchase". I have a client side event handler for the onclick of the checkbox. I need to find the row of the check box just checked. I do not want to use a gridclientselectcolumn because I don't want the user to be able to click anywhere in the row to select the row - I only want them to be able to select the row by clicking in the checkbox. What is the code needed on the javascript side to find what row was just clicked?

Thanks,
Laura

Improving Ajax request performance

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

Keep current menu item selected

Hi,

Can anyone tell me if there is a simple solution to this problem?
When I click a menu item (horizontal menu) or one of it's children, I must have the current menu item highlighted like when I hover over the item, but then fixed. If I click another item this item must get highlighted.

How can this be done?

Thanks in advance,

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 ???

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:
