[Solved] Achieve 3D effect with DatePicker

I am looking for the 3d effect that I can achieve using ASP controls such as textbox, dropdownlistbox etc by simply setting BackColor to White. I have found I can achieve this with RadTextBox by setting the backcolor along with setting Skin="". If I do that with datapickers or comboboxes, I lose all of the graphics associated with the controls. Any ideas on how to achieve this effect aside from designing a custom skin? Thanks

CompareValidator stops validating in hierarchy grid

Hi, I'm having problems getting my CompareValidator working inside my grid.

My grid uses a simple two level hierarchy. First level is a datetime, second level is a detail table with zero, one or more items.

In the detailtable there is a TABLE with a couple of TDs. These TDs are programmatically set to visible or invisible. Each TD has some controls.

One TD has a textbox and an input field (set to invisible), and also a Repeater that contains zero, one or more CompareValidators. Each CompareValidator validates against the invisible input field (which contains a copy of the parental user textbox).

I inject each CompareValidator in the Repeater ItemDataBound event handler.

This validation works until the value to compare results to false, and after that changing the value to a correct one does not cause the error message to disappear. Consequently, the form does not submit and the values in the grid are not updated nor validated.

I read that I should be using RadGrid's ItemCreated event handler to add CompareValidators but I cannot do that since it depends on each item in detail table if it has or not some special value. Also, I should be able to validate against more than one rule (indicated by the repeater) so there's the use of the repeater.

See code below. If anyone can shed light on the issue please do so!

    
                    protected void repeaterPoliticas_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)  
        
                    {  
        
                        RepeaterItem i = e.Item;  
        
                        if (i.ItemType == ListItemType.Item ||  
        
                            i.ItemType == ListItemType.AlternatingItem)  
        
                        {  
        
                            CompareValidator cv = (CompareValidator)i.FindControl("cvMontoPolitica");  
        
                            if (cv != null)  
        
                            {  
        
                                DataRow data = (DataRow)i.DataItem;  
        
                                HtmlInputText hdnAux = (HtmlInputText)i.FindControl("hdnAux");  
        
                                hdnAux.Value = ((TextBox)hdnAux.Parent.Parent.Parent.FindControl("txtMonto")).Text;  
        
                                cv.ControlToValidate = hdnAux.ID;  
        
                                cv.ValueToCompare = Convert.ToString(data["monto"]);  
        
                                cv.Operator = (ValidationCompareOperator)Convert.ToInt32(data["operador"]);  
        
                                TextBox txtMonto = ((TextBox)hdnAux.Parent.Parent.Parent.FindControl("txtMonto"));  
        
                                txtMonto.ToolTip = Convert.ToString(data["descripcion"]);  
        
                            }  
        
                        }  
        
                    }

ShowHeadersWhenNoRecords and CommandItemTemplate

Im having in issue using a hierarchy grid. In my GridTableView I have a CommandItemTemplate with an InitInsert CommantItem that works perfectly when there is data in the DetailTable and the header is showing. The problem is that I also have ShowHeadersWhenNoRecords = False for that same GridTableView.

When there is no data, it hides the headers like it should but it also hides the CommandItemTemplate so that no records can be added. This also happens when I'm using the default CommandItem instead of a CommandItemTemplate.

Is there anyway to get the CommandItemTemplate to show if there is not data, but still hide the headers? Here is a sample of my code...

    
            <DetailTables> 
        
                    <telerik:GridTableView runat="server" ShowHeader="true" DataKeyNames="ChecklistId"  NoDetailRecordsText="" ShowHeadersWhenNoRecords="false"   
        
                    EditMode="InPlace" Name="Checklist" CommandItemDisplay="top" Width="100%" HorizontalAlign="Right" CellPadding="0" CellSpacing="0">  
        
                        <CommandItemTemplate> 
        
                            <asp:LinkButton ID="btnAddNew" runat="server" CommandName="InitInsert" Text="Add New Record" CssClass="gridLink" /> 
        
                        </CommandItemTemplate> 
        
            ........

Script controls may not be registered after PreRender

I have received the above error from the Telerik data grid. The grid is bound to an LLBLGenDataSource control that returns an entity collection. However the data from this data source has a select parameter using a RadComboBox control. I need this as it reduces the amount of data I can view at any one time.

The problem arises when I enable this select parameters and set the grid to support paging. If I turn off the paging, the problem goes away, however I am left with a long result set. If on the other hand I comment out these select parameters, I am able to use paging but the number of pages increases.

I am using ajax by the way.

Can you guys help me?

[Solved] RadRotator in a floating RadDock

I have a RadRotator in a floating RadDock. The rotator's height is greater than the RadDock and the scroll bar is turned on. The elements inside of the rotator show beyond the RadDock and if you scroll the RadDock the contents of the rotator sometimes do not scroll with the scroll bar and sometimes they do but it is hugely delayed. It takes 10-20 seconds or more for the RadRotator contents to scroll (when they do).

Attached is a picture of the results.

Radgrid update and insert edit forms at the same time

I have a grid with the ability to add and update items via the standard controls.

However, if I click to add a record and then click on "edit" on another record then both forms will be displayed at the same time. Is there any method of preventing this behavior to ensure that only one form or the other is displayed?

TIA,

Jason
