Pagging problem

When I push the pagging button, I got this error message:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

What causes this problem ?

Related Comboboxes in Repeater

Using related combo boxes Continent, Country, City as an example. If I were to implement the related combo boxes inside a .NET repeater control, what is the best approach to do this? Let's say, I have two rows in a repeater, each row has its own related combo boxes. Do I need to create new javascript set for every row? Any suggest is greatly appreciated.

Specifying skin for dropdown column

I have a grid and a skin specified for that and it works fine. However, on the contained GridDropDownColumn columns, when it shifts to edit mode, the combo box is created nicely, but does NOT inherit the skin of the grid as the text boxes do. This results is a mixture of font sizes in the edit row (inline edit).

How can I tell the created ComboBox which skin to use?

Thanks!

[Solved] InvalidStyleDuration

In all current examples on RadNumericTextBox with spinbuttons I see InvalidStyleDuration="100". Without this setting, my control with spinbuttons doesn't format properly. The help doesn't say anything.

What is the meaning of this property, how and when is it supposed to be used?

Adding Alert message for specific nodes at runtime

Hi,

I want to add an alert message to some nodes in my RadTreeView.
Following is my code.

    
            int temp = 0;  
        
                    foreach (RadTreeNode node in rdtreeTeamBrand.Nodes)  
        
                    {  
        
                        if (node.Nodes.Count > 0)  
        
                        {  
        
                            for (int i = 0; i < node.Nodes.Count; i++)  
        
                            {  
        
                                RadTreeNode brandNode = node.Nodes[i];  
        
                                foreach (DataRow row in tblTeamBrandDetails.Rows)  
        
                                {  
        
                                    if (node.Value == row["TeamID"].ToString() && brandNode.Value == row["BrandID"].ToString())  
        
                                    {  
        
                                        node.Checked = true;  
        
                                        brandNode.Checked = true;  
        
                                        temp = Convert.ToInt32(objconfig.CheckBrandSwotForPlanPeriod(Convert.ToInt32(node.Value), Convert.ToInt32(brandNode.Value), PlanningPeriodID));  
        
                                        if (temp != 0)  
        
                                        {   //this is where im adding the radalert at..  
        
                                            brandNode.Attributes.Add("onclick",   
        
                                                string.Format(@"    
        
                                            function _showAlert() {{Sys.Application.remove_load(_showAlert);       
        
                                            radalert('{0}', null, 100, '{1}');}};       
        
                                            Sys.Application.add_load(_showAlert);", "Brand will be excluded from the PlanningPeriod.", "Novartis iPlan"));  
        
                                            brandNode.ForeColor = System.Drawing.Color.Navy;  
        
                                        }  
        
                                    }  
        
                                }  
        
                            }  
        
                        }  
        
                    }

This is how a part of the Treeview looks in html

    
            <div class="rtTop">  
        
                                                    <span class="rtSp"></span><input type="checkbox" class="rtChk" /><span class="rtIn">AFIN</span> 
        
                                                </div></li><li class="rtLI"><div class="rtMid">  
        
                                                    <span class="rtSp"></span><input type="checkbox" class="rtChk" /><span class="rtIn">FEM</span> 
        
                                                </div></li><li class="rtLI"><div class="rtMid">  
        
                                                    <span class="rtSp"></span><input type="checkbox" class="rtChk" checked="checked" /><span class="rtIn" onclick="     
        
                                            function _showAlert() {Sys.Application.remove_load(_showAlert);        
        
                                            radalert('Brand will be excluded from the PlanningPeriod.', null, 100, 'Novartis iPlan');};        
        
                                            Sys.Application.add_load(_showAlert);" style="color:Navy;">PROLE</span> 
        
                                                </div>

This is not working. I am getting a alert with null as text, onclick of these nodes.

Please help.

Using an ASPX page as a Tools File

I'm painfully converting my solutions from Q2 2007 to Q1 2009 AJAX. One thing I'm having a problem with is the ToolsFile for RadEditor. In the past, I used an ASPX page to provide dynamic content to the control (especially the links). When I try to do this now, it doesn't work, I get an error. It appears as if the control is not executing the page, but is rather reading it as if it were a text file, which means the dynamic content will not be included, and an error will occur (as the page tag is incorrectly processed). Am I right about this? Is there any workaround?

[Solved] _1ca is null calander is not poping up

Hey Telerik team,

I am facing some weird problem. In my page, I have a Gridview and and an HTML table containing 2 Telerik Calandar controls. Table is hidden at page load.

GridView:
<asp:GridView ID="uxtechgrid" runat="server" BorderStyle="None" ShowHeader="True"

Width="75%" AutoGenerateColumns="False" EmptyDataText="No records found" OnRowCommand="uxtechgrid_RowCommand"

OnRowEditing="uxtechgrid_RowEditing" OnRowCreated="uxtechgrid_RowCreated">

<asp:TemplateField ItemStyle-Width="30%" HeaderText="Review Step">

<asp:LinkButton runat="server" ID="action" Text='<%# Bind("WorkflowItemTemplateName") %>'

CausesValidation="false" CommandArgument='<%# Bind("WorkflowitemtemplateID") %>'

CommandName="Edit"></asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField ItemStyle-Width="30%" HeaderText="Review Group Type" ItemStyle-HorizontalAlign="Center"

DataField="WorkflowItemTemplateTypeName"></asp:BoundField>

<asp:BoundField ItemStyle-Width="20%" HeaderText="Start Date" ItemStyle-HorizontalAlign="Center"

NullDisplayText="Not Assigned" HtmlEncode="false" DataFormatString="{0:d}" DataField="StartDateString">

</asp:BoundField>

<asp:BoundField ItemStyle-Width="20%" HeaderText="End Date" ItemStyle-HorizontalAlign="Center"

NullDisplayText="Not Assigned" HtmlEncode="false" DataFormatString="{0:d}" DataField="EndDateString">

</asp:BoundField>

</Columns>

</asp:GridView>

and HTML table is like :

<

tr id="uxDynamic" runat="server" visible="false" align="center" style="width: 100%">

<table>

<tr>

Review Step:

<asp:Label ID="uxReviewStep" runat="server"></asp:Label>

<asp:Label ID="uxWrkFlwTmpID" Visible="false" runat="server"></asp:Label>

</th>

</tr>

<tr>

<th>

Start Date:

</th>

<td>

<telerik:RadDatePicker ID="uxStartDate" runat="server" MinDate="2006-01-01" SharedCalendarID="sharedCalendar"

Skin="Gray" Culture="English (United States)">

</DateInput>

</telerik:RadDatePicker>

<asp:RequiredFieldValidator runat="server" Display="Dynamic" ID="Requiredfieldvalidator1"

ValidationGroup="grp" ControlToValidate="uxStartDate" ErrorMessage="Please select start Date."></asp:RequiredFieldValidator>

</td>

</tr>

<tr>

<th>

End Date:

</th>

<td>

<telerik:RadDatePicker ID="uxEndDate" runat="server" MinDate="2006-01-01" SharedCalendarID="sharedCalendar"

Skin="Gray" Culture="English (United States)">

</DateInput>

</telerik:RadDatePicker>

<asp:RequiredFieldValidator runat="server" Display="Dynamic" ID="Requiredfieldvalidator2"

ValidationGroup="grp" ControlToValidate="uxEndDate" ErrorMessage="Please select End date."></asp:RequiredFieldValidator><br />

<asp:CompareValidator ID="dateCompareValidator" runat="server" ControlToValidate="uxEndDate" Display="Dynamic"

ControlToCompare="uxStartDate" Operator="GreaterThan" Type="Date" ErrorMessage="The End Date cannot be before the Start Date<br /><br />">

</asp:CompareValidator>

</td>

</tr>

<

tr>

<asp:Button ID="uxSubmit" runat="server" OnClick="submitButton_Click" Text="Submit"

ValidationGroup="grp" />

</td>

</tr>

<

div style="display: none">

<telerik:RadCalendar ID="sharedCalendar" Visible="false" runat="server" EnableMultiSelect="false"

UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x"

RangeMinDate="2006/01/01" Skin="Gray" />

<asp:PlaceHolder ID="sharedCalendarPlaceHolder" runat="server"></asp:PlaceHolder>

</div>

Now on click of Hyperlink Column in Grid, We display the "TR" showing 2 Datepickers using shared Calendar. It works fine when I click on first(any) Hyperlink; both the calendar opens perfectly. But on clicking Second time any Hyperlink, it shows just first calendar not Second. In Javascript it shows "_1ca" as null; I guess that is stopping it to show. Can you please help me out?

Please let me know if you need any other details!

Thanks in Advance!
