I have a grid with a formtemplate. The formtemplate has 4 buttons: Save (CommandName="Update"), Cancel (CommandName="Cancel"), GoToStart (OnClick="btnGoToStart_Click"), PrintToPdf (OnClick="btnPrintToPdf_Click"). As you can see 2 of the buttons perform a grid command, and 2 of the buttons has their own click events. After clicking the Save button or Cancel button, the grid does exactly what's expected. But, if I click on Save, and then click on GoToStart or PrintToPdf buttons, they do not enter theis events, but acts like the Cancel button. What am I missing here?

[Solved] Postbacks alternate between partial and full with RenderInPageRoot=true

Hello,

I have a page where I am using tooltips to change items like this:

Contact E-mail: me@somewhere.com change <--clicking change brings up a tooltip with the textbox to change the e-mail address.

I have a conundrum. Using the tooltip with RenderInPageRoot set to false, my tooltip will appear in the incorrect position, then "jump" up next to the element. This is due to the way my styles are defined, and unfortunately I cannot change them. However, ajax postbacks work great in this scenario.

However, if I use RenderInPageRoot=true, the tooltip shows up perfectly next to the element, but then I get the behavior where Ajax will work on the first postback, not on the next, then again on the next. So it alternates between partial and full postbacks.

Here is a snippet of the code:

    
            <div class="block append-bottom-sm"> 
        
                        <div class="span-6"> 
        
                            <asp:Label ID="lblContactEmailTitle" runat="server" Text="Contact E-mail:" AssociatedControlID="lContactEmail" /> 
        
                        </div>
        
                        <div class="span-5"> 
        
                            <asp:Label ID="lContactEmail" runat="server"></asp:Label> 
        
                            <telerik:RadToolTip runat="server" ID="radttContactEmail" HideEvent="FromCode" Position="MiddleLeft" 
        
                                Width="250px" Height="70px" Animation="Slide" ShowEvent="OnClick"  ShowDelay="0"  RenderInPageRoot="true" 
        
                                RelativeTo="Element" TargetControlID="lbContactEmail"> 
        
                                <asp:Label ID="Label5" runat="server">Please enter your Contact Email:</asp:Label> 
        
                                <br /> 
        
                                <asp:TextBox ID="tbContactEmail" runat="server" ValidationGroup="ContactEmailValidationGroup"></asp:TextBox> 
        
                               <br /> 
        
                                <asp:RegularExpressionValidator  ID="revContactEmail" runat="server" ValidationGroup="ContactEmailValidationGroup" Display="Dynamic" 
        
                                ValidationExpression="^[\w\.\-]+@[a-zA-Z0-9\-]+(\.[a-zA-Z0-9\-]{1,})*(\.[a-zA-Z]{2,3}){1,2}$" 
        
                                ControlToValidate="tbContactEmail">The Contact Email must have a valid format.</asp:RegularExpressionValidator>                   
        
                                <asp:LinkButton ID="lbContactEmailSave" runat="server" ValidationGroup="ContactEmailValidationGroup">Save</asp:LinkButton> 
        
                                <asp:LinkButton ID="lbContactEmailCancel" runat="server" ValidationGroup="" CausesValidation="false" OnClientClick="HideTooltip(); return false;">Cancel</asp:LinkButton> 
        
                            </telerik:RadToolTip> 
        
                        </div> 
        
                        <div class="span-3"> 
        
                            <asp:LinkButton ID="lbContactEmail" runat="server" OnClientClick="SetContactEmail();">Change</asp:LinkButton> 
        
                        </div> 
        
                    </div>

Here is the AjaxManager setup (pnlContactInfo surrounds all the code that you see in the snippet above):

    
            <telerik:RadAjaxLoadingPanel ID="radalp" runat="server" BackgroundPosition="Center" Skin="Default" /> 
        
                    <telerik:RadAjaxManager ID="radam" runat="server" EnablePageHeadUpdate="false" DefaultLoadingPanelID="radalp" > 
        
                        <AjaxSettings>                 
        
                            <telerik:AjaxSetting AjaxControlID="lbContactEmailSave"> 
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="pnlContactInfo" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
                    </telerik:RadAjaxManager>

Here is the javascript function that is called when the user clicks the "Change" button:

    
             function SetContactEmail() { 
        
                    document.getElementById('<%=tbContactEmail.ClientID%>').value = document.getElementById('<%=lContactEmail.ClientID%>').innerHTML; 
        
                    Page_ClientValidate('ContactEmailValidationGroup'); // Erase any message which may have been displayed the last time after a Cancel was clicked. 
        
                }

And here is the code-behind that is happening on save:

    
             Private Sub lbContactEmailSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbContactEmailSave.Click 
        
                    Dim VZID As String = hidVZID.Value 
        
                    Dim newEmail As String = tbContactEmail.Text 
        
                    Dim SQL As String = 'some sql here... 
        
                    Dim myData As New clsData() 
        
                    myData.ExecuteSQL(SQL, CommandType.Text) 
        
                    lContactEmail.Text = newEmail 
        
                End Sub

Any help would be greatly appreciated.

Thanks,

RadScheduler Contol Delete Event gets Fired Twice...

Hello,

I have below RadScheduler control on my page. Code as below:

<asp:Content ID="Content1" ContentPlaceHolderID="main" runat="Server">

<telerik:RadScheduler runat="server" ID="schedular" DataKeyField="ID" DataSubjectField="Subject"

DataStartField="Start" DataEndField="End" StartEditingInAdvancedForm="true" DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentID" OnAppointmentInsert="schedular_AppointmentInsert"

OnAppointmentDelete="schedular_AppointmentDelete" StartInsertingInAdvancedForm="true">

</telerik:RadScheduler>

</asp:Content>

I can insert the appointment easily but when I delete the appointment the Delete event (OnAppointmentDelete = "schedular_AppointmentDelete") gets Fired twice.

If I remove the recurrence properties (i.e.DataRecurrenceField, DataRecurrenceParentKeyField) then it works fine but I need Recurrence functionality.

Please let me know the solution to this problem.

Thanks,
Mayur.

Freeze Header and column for dynamically generated RadGrid

Hi,
I have used a dynamically generated RadGrid for my application.
I would like to use the following functions:
1) Freeze header
2) Freeze columns
3) Resize one of the column
I know there's an article saying that resizing the column does not work with freezing header, so if we are to only use the freeze header and columns there are still some issues

here's the issues and settings I used:
- Freeze header only, no freezing columns
The grid has some alignment issue when scroll to the end, the header and content line is not aligned.
Pls see freezeheaderalignment.jpg
- Freeze header and column (must use layout = auto to make it show)
The last column disappear when using both freeze header and column and somehow the header height become very big and is it because of my fixed height, now i have 3 vertical scroll bars :(
Pls see freezeheaderncolumn.jpg

Also I noticed that I have to specify the width of each column otherwise the column will shrink, is there any auto-size property to automatically resize the column width as per content?

Here's my code:

RadGrid1 = new RadGrid();

RadGrid1.ID = "RadGrid1";

RadGrid1.Height = Unit.Pixel(535);

int intDefaultPercentage = 99;

bool isFixed = false;

if (!ConfigHelper.OPDashboardLayout.Equals(""))

Forcing the tabs to look like they're on the 2nd level.

OK.

This is a bit of a strange one.

I have a page with a tabstrip and multipage control on it.

When one of the tabs is selected, the pageview contains another tab strip with it's own multipage control.

Obviously, when this control shows, the tabs are all 'level one' tabs. Is it possible for me to force the tabs in this inner control to appear like 2nd level tabs?

RadGrid MasterTable CommandItemTemplate is not working

HI,

I have a Radgrid(ASP.NET Ajax) with MasterTable and DetailTables.
I have given CommandItemTemplate in MasterTableView. Below is just the part of my code.

<telerik:RadGrid runat="server" ID="rgSurvey" AutoGenerateColumns="false" ShowStatusBar="true"

AllowAutomaticInserts="false" Skin="Outlook" OnItemCommand="rgSurvey_ItemCommand"

OnPreRender="rgSurvey_PreRender">

<MasterTableView DataKeyNames="SurveyID" SkinID="Outlook" Width="100%" CommandItemDisplay="Top"

Name="Survey">
<DetailTables>

<telerik:GridRelationFields DetailKeyField="SurveyID" MasterKeyField="SurveyID" />

</ParentTableRelation>

<asp:LinkButton ID="lnkAddstaff" runat="server" Text="Add Staff to Survey" CommandName="Popup"></asp:LinkButton>

</CommandItemTemplate>

</telerik:GridTableView>

</DetailTables>

<asp:LinkButton ID="lnkAdd" runat="server" Text="ADD" CommandName="Insert"></asp:LinkButton>

</CommandItemTemplate>

The CommandItemTemplate [CommandName="Insert"] inside the MAsterTableView is not working.. But the CommandItemTemplate inside DetailTables is working. Not sure why this is happening.

We have a asp.net Master page and Content page(Default.aspx). When using the RadGrid without a master page its working fine.
Are they any known issues when using RadGrid and MAsterTableView inside an asp.net Content page?

Regards,
Dayanithy

[Solved] e.Text not clearing out in ItemsRequested event

I am checking the e.Text value (RadComboBoxItemsRequestedEventArgs) in the ItemsRequested handler for a RadComboBox. If I type in one or more characters, it works fine. As I delete them, it works fine. Once I delete the last character, however, the e.Text property retains the last character entered.

For example:
Enter "s" -> e.Text = "s"
Enter "sm" -> e.Text = "sm"
Delete "m" ->e.Text = "s"
Delete "s" (textbox is empty) -> e.Text still = "s"
