Hi,

I have the following code in the RadGrid of my UserControl:

                    <telerik:GridTemplateColumn UniqueName="MyColumnName" HeaderText="MyColumnName" Visible='<%# (Mode == SearchAndSelectMode.DataMode) ? true : false %>'>         
                <ItemTemplate>         
                    <asp:ImageButton ID="MyButton" runat="server" ImageUrl="../App_Themes/eventIS/Grid/MyButton.gif" CommandName="DoSomething" />         
                </ItemTemplate>         
            </telerik:GridTemplateColumn>         

The "Mode" property is a public property of my UserControl, and I want to display this column depending on the value of that property. But when I run it, the following error appears:

Databinding expressions are only supported on objects that have a DataBinding event. Telerik.Web.UI.GridTemplateColumn does not have a DataBinding event.

I know it is also possible to hide the columns in code behind, but I want to do it in the ascx because then it is more clear what happens in my opinion. Is there any way to achieve what I want with the RadGrid?

Automatic Update with Ajax doesn't work

Hello,

I have a RadGrid with a simple definition, automaticinsert and update allowed:

    
            <telerik:RadGrid ID="MainGrid" runat="server" SkinID="Admin" AllowPaging="True" AllowAutomaticInserts="True" 
        
              AllowAutomaticUpdates="True" DataSourceID="ObjectDataSourceMain"> 
        
              <MasterTableView DataKeyNames="Id"> 
        
                <Columns> 
        
                  <telerik:GridBoundColumn HeaderText="Název katalogu" DataField="Name"> 
        
                  </telerik:GridBoundColumn> 
        
                  <telerik:GridBoundColumn HeaderText="Rok" DataField="Year"> 
        
                  </telerik:GridBoundColumn> 
        
                  <telerik:GridCheckBoxColumn HeaderText="Aktivní" DataField="IsActive"> 
        
                  </telerik:GridCheckBoxColumn> 
        
                </Columns> 
        
              </MasterTableView> 
        
            </telerik:RadGrid> 
        
            <asp:ObjectDataSource ID="ObjectDataSourceMain" runat="server" OldValuesParameterFormatString="Original_{0}" 
        
              SelectMethod="GetCatalogs" UpdateMethod="UpdateCatalog" InsertMethod="CreateCatalog" 
        
              TypeName="Kooperativa.KoopObchod.Facade.ProductFacade"> 
        
              <UpdateParameters> 
        
              </UpdateParameters> 
        
              <InsertParameters> 
        
              </InsertParameters> 
        
            </asp:ObjectDataSource>

Everything works fine till RadAjaxManager is added:

    
            <telerik:RadScriptManager ID="RadScriptManager" runat="server" />
        
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
              <AjaxSettings> 
        
                <telerik:AjaxSetting AjaxControlID="MainGrid"> 
        
                  <UpdatedControls> 
        
                    <telerik:AjaxUpdatedControl ControlID="MainGrid" /> 
        
                  </UpdatedControls> 
        
                </telerik:AjaxSetting> 
        
              </AjaxSettings> 
        
            </telerik:RadAjaxManager>

Then I get client error:

"Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: Exception has been thrown by the target of an invocation."

Insert works fine. This problem occured on all my grids.

How to find the problem? Thank you

Displaying a one-dimensional list of objects with a collapsble items

Hi - I have a list of domain object called D with properties Name and Id as well as others.

Now, I want to have the RadPanelBar display this list of Items as follows:

[d1.Name ^]

showing detailed information about d1.

</TemplateItem>

[d2.Name ^]

showing detailed information about d2.

</TemplateItem>

etc.

I cannot get RadPanelBar to give me this list with the collapse option.

The list D's is dynamic and I currently set it directly on the DataSource property of RadPanelBar.

Can anyone point me to a solution or offer any help?

Regards

Thomas

How to load the treeview using JSON

Hi All,

I really need to know how to load the treeview on the client using JSON. All I've seen is using an XML file and this will not fit the bill for my needs. It would seem rather wastefull to take a JSON string and create an XML file out of it just to load the treeview on the client side. Any assistnace, code, snips or links to other articles would be terrific as I need to figure this out asap.

With regards and advance thanks

Edit Appointment Subject on the Button Click

Hi All,

I am implementing the Rad Scheduler Control by creating the Appointments through Drag and Drop feature.I implemented a Advance Edit Form where i took two comboboxes with tasks and the BreakTime...
and on the top of the scheduler i took 3 buttons TaskView,BreakView and Shift(appointment)View.
so when ever i click on the button the subject of the appointement should be updated based on the selected one.(say if i clicked on the task view ,the subject field should contain the tasks assigned for that appointment).I tried it writting the code inside the appointment -created event but i am getting the error as "Collection was modified; enumeration may not execute " I dont know the reason why i am gettiing this..
Here is the code i implemented..

protected

void RSchedulerTemplate_OnAppointmentCreated(object sender, AppointmentCreatedEventArgs e)
{

ViewScheduler(

string ViewType);
}
privatevoid ViewScheduler(string ViewType)
{

for (int i = 0; i < DRMSession.DTScheduler.Rows.Count; i++)

TimeSpan startOffSet = new TimeSpan(startTime.Hours, startTime.Minutes, 0);

DateTime startOffSetDate = new DateTime(startOffSet.Ticks);

// assign duration hours and minutes

TimeSpan duration = new TimeSpan(endTime.Hours, endTime.Minutes, 0);

DateTime durationDate = new DateTime(duration.Ticks);

// startOffSet and duration formatting result

string startOffSetResult = startOffSetDate.ToString("hh:mm tt");

string durationResult = durationDate.ToString("hh:mm tt");

string jobGroupName = string.Empty;
