Hi,

I am working on a rather large web app that has separate instances of the same web user control used on multiple steps of an ASP.NET Wizard control.

I am triggering an ajax postback via javascript:

 

var manager = $find("<%=RadAjaxManager.GetCurrent(Page).ClientID %>");

var textBoxId = "<%= txtSearchFilter.UniqueID %>";

if (manager && textBoxId) {

    manager.ajaxRequestWithTarget(textBoxId, searchText);

}

 

 

 

The web user control's markup contains the following:

 

The problem I'm experiencing is that the loading panel shows up correctly in the first step of the wizard, but on subsequent steps that utilize the same web user control, the loading panel does not show up.

All data posts correctly on the subsequent steps, but the loading panels do not display. My first thought was that the code was getting confused with the control clientIDs, but it appears as if the rendering for each step is putting the right id values into my javascript server blocks. I'm not sure how to verify that the loading panel is targeted to the correct clientID values though when looking at the source for the rendered page.

I am removing the loading panels for now to keep the look and feel uniform for each step, but I would really like to solve this problem as the loading panels definitely add something to the user experience.

Thanks,

Charlie

I am having an Ajax Loading Panel display on sorting a RadGrid and put a MinDisplayTime on the Loading Panel. When I sort, the loading image starts to animates, stops briefly when the request is finished then restarts to complete the MinDisplayTime. Is there anyway to prevent the slight shutter from occurring when the request is complete?

• Problem:

in index.aspx file, when html, body, form { height:100% }, and Radeditor1's ContentAreaCssFile: EditorContentAreaStyles.css, its height will be inherited as default value from index.aspx.
so in iframe, body's height is less than length of the text in editor.
when i remove height:100% from index.aspx, it work fine.
thanks.

I have a Javascript function that opens a radwindow and then tries to call a function in that window.  It seems liek this should be pretty easy, but I can't get it to call that function.  Here's the calling function:

function openNewWindow(agentID, contractID, company)
            {
                var tabs = tabStrip.get_tabs();
                var tabval = 0;
                var tabFound = false;
                // loop through the tabs looking for existing agent
                for (var i = 0; i < tabs.get_count(); i++) {
                    tabval = tabs.getTab(i).get_value();
                    if (tabval == agentID) {
                        tabFound = true;
                        var oWnd = tabs.getTab(i).correspondingWnd;
                        break;
                    }
                }
                // if agent is already open, alert user and don't open again
                if (tabFound == false) {
                    var oWnd = radopen("AgentWin.aspx?HeaderID=" + agentID, null);
                    oWnd.set_title(agentID);
                    oWnd.maximize();
                    tabStrip.trackChanges();
                    //create a new tab
                    var tab = new Telerik.Web.UI.RadTab();
                    //set the text of the tab
                    tab.set_text(agentID);
                    oWnd.correspondingTab = tab;
                    //add the tab to the tabstrip
                    tabStrip.get_tabs().add(tab);
                    tabStrip.repaint();
                    tab.correspondingWnd = oWnd;
                    tabStrip.commitChanges();
                    //Select this tab
                    tab.select();
                    
                    oWnd.get_contentFrame().contentWindow.CallContractsWindow(agentID, contractID, company);
                }
            }


Since I open the radwindow in this function, I already have have the reference to it (oWnd), so I thought I could just use that last line to call a function in the opened window.  But that last line gives me - "Error: Object doesn't support this property or method"

Can anyone tell me what I'm doing wrong?  Thanks!

Hi,

We have a RadGrid with Groupable columns, when the user group all the GroupHeaders has a white background with more height of usual like the first picture (CorrectLayout.jpg). When i Turn off the "AllowScroll=False" the GroupHeader layout behavior is correct for all the groups.

RadGrid aspx code:


Hope you can help me with this.

Best Regards,

I am using Visual Studio 2008.  I have several projects using Telerik TabStrips with multipage controls.  I always work on designing the page in "Split" mode where the source is at the top of the screen and the design view is at the bottom.

One thing I find annoying is when I am working on a project, and I want to select a particular button, label, table row, or whatever within one of the PageViews.  Instead of the Source jumping me to that element and highlighting it as expected, instead I am jumped to the top of the PageView that element is contained within and the entire PageView is highlighted.  I then have to manually scroll down and find the element I was trying to access by sight.

Is there a setting or something I can do so Visual Studio will select the element contained within the PageView and not the entire PageView itself?

Hey everyone

I am using a radgrid and some GridDropDownColumns for displaying possible values when the user selects the edit command button. The problem is that the grid is displaying some values as it is supposed and others not, I am binding the grid programmatically at the code behind and sending a dataset with the values for the Master Table and for the drop down columns. The problem is only in the display, in edit mode the grid is working fine, I'm able to show the possible values in the columns as wondered.

here is the code...

aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"

        GridLines="None" MasterTableView-NoMasterRecordsText="No hay registros que mostrar">

        <MasterTableView DataKeyNames="ProductoId" Name="Productos" EditMode="InPlace">

        <Columns>

        <telerik:GridNumericColumn UniqueName="columnProductoId" HeaderText="ProductoId" DataField="ProductoId" Visible="false"></telerik:GridNumericColumn>

       

        <telerik:GridDropDownColumn UniqueName="columnTipoProducto"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnPaisMoneda"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnEstado"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnOperador"></telerik:GridDropDownColumn>

       

        <telerik:GridBoundColumn UniqueName="columnDescripcion" HeaderText="Descripcion" DataField="Descripcion">

        </telerik:GridBoundColumn>

        <telerik:GridNumericColumn  UniqueName="columnValor" HeaderText="Valor" DataField="Valor">

        </telerik:GridNumericColumn>

       

        <telerik:GridDateTimeColumn UniqueName="columnFechaRegistro" HeaderText="Fecha de Registro" DataField="FechaRegistro">

        </telerik:GridDateTimeColumn>

        <telerik:GridEditCommandColumn UniqueName="EditCommandColumn" EditText="Editar">

        </telerik:GridEditCommandColumn>

        <telerik:GridButtonColumn CommandName="Delete" ConfirmDialogType="RadWindow" ConfirmText="Está seguro de que desea eliminar este producto?" Text="Eliminar" UniqueName="DeleteColumn">

        </telerik:GridButtonColumn>

        </Columns>

            <RowIndicatorColumn>

                <HeaderStyle Width="20px" />

            </RowIndicatorColumn>

            <ExpandCollapseColumn>

                <HeaderStyle Width="20px" />

            </ExpandCollapseColumn>

        </MasterTableView>

    </telerik:RadGrid>

vb code behind:

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

        Try

            Me.RadGrid1.DataSource = Me.FuenteDatosGrillaPinesProducto

            'here is where i send the dataset with all the DataTable               needed

            Me.RadGrid1.DataMember = "Tabla Pines Producto"

            Dim columna As GridDropDownColumn

 

            columna = Me.RadGrid1.Columns(1)

            With columna

                .DataSourceID = Me.RadGrid1.DataSourceID

                .HeaderText = "Tipo de producto"

                .DataField = "TipoProductoId"

                .ListTextField = "Descripcion"

                .ListValueField = "TipoProductoId"

                .DataSourceID = "Pines Productos"

                .ListDataMember = "Tabla Tipos Producto"

            End With

 

            columna = Me.RadGrid1.Columns(2)

            With columna

                .DataSourceID = Me.RadGrid1.DataSourceID

                .HeaderText = "Pais"

                .DataField = "PaisMonedaId"

                .ListTextField = "Descripcion"

                .ListValueField = "PaisId"

                .DataSourceID = "Pines Productos"

                .ListDataMember = "Tabla Paises"

            End With

 

            columna = Me.RadGrid1.Columns(3)

            With columna

                .DataSourceID = Me.RadGrid1.DataSourceID

                .HeaderText = "Estado"

                .DataField = "EstadoId"

                .ListTextField = "Descripcion"

                .ListValueField = "EstadoId"

                .DataSourceID = "Pines Productos"

                .ListDataMember = "Estados"

            End With

 

            columna = Me.RadGrid1.Columns(4)

            With columna

                .DataSourceID = Me.RadGrid1.DataSourceID

                .HeaderText = "Operador"

                .DataField = "OperadorId"

                .ListTextField = "Descripcion"

                .ListValueField = "OperadorID"

                .DataSourceID = "Pines Productos"

                .ListDataMember = "Tabla Operadores"

            End With

 

        Catch ex As Exception

 

        End Try

    End Sub

the result is something like this:
Tipo de producto   Pais            Estado                 Operador     Descripcion   Valor   Fecha Registro
PINEs                     Colombia    Producto Activo   Operador1   Pin de 500     500     13/03/2009
                                                                                                 Pin de 1000  1000    13/03/2009
PINEs                     Venezuela   Producto Activo   Operador1  Pin de 500     500     13/03/2009

as you can see the second row doesn't show anything on the columns that are grid drop down columns.

I don't know if you got the idea of my problem so far, thanks for your time

Hi,

From the example on this page http://demos.telerik.com/aspnet-ajax/scheduler/examples/optimizedqueries/defaultcs.aspx# 

SELECT * FROM [Appointments] WHERE ([Start] < @RangeEnd AND [End] > @RangeStart) OR ([RecurrenceRule] <> '') OR ([RecurrenceParentID] IS NOT NULL) 

I see that the select statement retrieved recurring events events using [RecurrenceRule] <> '' which is good. My question is why do you need the "OR ([RecurrenceParentID] IS NOT NULL)" ? From what I understand, an appointment has RecurrenceParentID only when it's modified from a recurring series and then a new row in Appointments table will be created. The first where clause (start < @rangeEnd...) should already retrieve those in the visible start/end. If you include the RecurrenceParentID IS NOT NULL wouldn't that unnecessary retrieve more appointments than needed?

Thanks
