[Solved] Update all controls in table or div

I came across the following http://www.telerik.com/help/aspnet-ajax/ajxclientsideperformance.html saying I could update a containing table or div rather than individual controls, and thought I would use this as I have a table containing about 20 controls that all need updating, so changed RadAjaxManager from updating each individual control to update either the table or the containing div, but neither seems to update the controls within the table.

Is this meant to be OK?

[Solved] How to detect when spellchecker has modified the textbox?

Hi,
I need to detect when spellchecker modified the texts in the textbox so I can raise the isDirty flag.
I tried implementing my own isDirty flagging by comparing value of the textbox with original texts when OnClientCheckFinished is called, but the problem is OnClientCheckFinished is called before any of the textbox has actually been modified. Is there any other solution to this that might work?
Thanks!

Filter Menu "Between" option issue

Hi,

In the Radgrid, if I try to filter by a date column between two times it doesn't work. Basically I want to see all the records between "01/10/2010 12:00:00" to "11/10/2010 12:00:00". I would like to see this by entering the text - "01/10/2010 12:00:00 11/10/2010 12:00:00" in the Filter Textbox and selecting "Between" Filter Menu option on a DateTime column.

But I don't get the desired result. Infact as soon as radGrid encounters more than one space between a string it empties that string and makes CurrentFilterValue for that columns as a empty string. Can I make RadGrid not do so?

Filtering options that works on Radgrid are as follows:
- "01/10/2010 12:00:00" -> EqualTo, Greater Thans, etc.
- "01/10/2010" -> EqualTo, Greater Thans, etc.
- "01/10/2010 11/10/2010" -> Between.

Filtering options that DO NOT work on Radgrid are as follows:
- "01/10/2010 12:00:00 11/10/2010 16:30:00" -> Between. - I WANT THIS TO WORK

I am override the RaisePostBackEvent, but the filter value in the above case is emptied out.

Any help?

Thanks

[Solved] Add ColorPickerItem Argument

Hi,

I am using a color picker for an ecommerce site. I am using it as a color swatch for the user to select the color of shirt they want. Everything is working as expected with one exception. I need to find a way to add another argument to the ColorPickerItem in addition to the value and title.

The logic works like this. The admin adds an attribute such as 'color' to the product. The attribute is assigned a control (ColorPicker). The admin then adds values to the control (Red, Blue, White, etc.). The ecommerce site logic usually works with a dropdown control which also has only 2 arguments (value, text). The value is the database value of the 'attribute-value' (Red-id, Blue-id, etc.). How can I add another argument to RadColorPicker such as RadColorPicker(int Id, Color value, String title).

Here is some code: Hope this makes sense.

                    ///***Add ColorSwatch Control         
                                        case AttributeControlTypeEnum.ColorSwatch:         
                                            {         
                                                ///***Define RadColorPicker Attributes         
                                                RadColorPicker rcpColorSwatch = new RadColorPicker();         
                                                rcpColorSwatch.ID = attribute.ProductAttribute.Name;         
                                                rcpColorSwatch.Preset = ColorPreset.None;         
                                                rcpColorSwatch.ShowEmptyColor = false;         
                                                rcpColorSwatch.PreviewColor = false;         
                                                ///***Add Attribute Collection Values to ColorPickerItemCollection         
                                                ProductVariantAttributeValueCollection pvaValues = attribute.ProductVariantAttributeValues;         
                                                foreach (ProductVariantAttributeValue pvaValue in pvaValues)         
                                                {         
                                                    string pvaValuepvaValueName = pvaValue.Name;         
                                                    decimal priceAdjustmentBase = TaxManager.GetPrice(productVariant, pvaValue.PriceAdjustment);         
                                                    decimal priceAdjustment = CurrencyManager.ConvertCurrency(priceAdjustmentBase, CurrencyManager.PrimaryStoreCurrency, NopContext.Current.WorkingCurrency);         
                                                    if (priceAdjustmentBase > decimal.Zero)         
                                                        pvaValueName += string.Format(" [+{0}]", PriceHelper.FormatPrice(priceAdjustment, false, false));         
                                                    ColorPickerItem cpiValueItem = new ColorPickerItem((ColorTranslator.FromHtml(pvaValue.ProductVariantAttributeValueID.ToString())), (pvaValueName));         
                                                    rcpColorSwatch.Items.Add(cpiValueItem);                                          ///Above-This is the ValueId of color.  I need this plus the color value        
                                                }

Clearing Filter

I been trying to clear the filter through code behind methods.

I set each columns to

column.CurrentFilterFunction =

GridKnownFunction.NoFilter;

Then I rebind the grid

The grid then refreshes but all the records are missing. I would have expected the grid to show all records...

So how do I programatically clear the filter in code behind c# and have the grids show all records.

I am just frustrated I missed something and google this time has failed me.

Thanks in advance

[Solved] Client Side functions (get_isItemInserted)

hi all,

i have a custom validator for a RadUpload control in the grid. i want the validator to validate empty text only on insert not on update, on update it's not required to upload a file but if the user selected one it should get validated.

i have put this code in ItemDataBound

    
                Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound  
        
                    If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then 
        
                        Dim item As GridEditableItem = CType(e.Item, GridEditableItem)  
        
                        Dim imageValidator As CustomValidator = CType(item.FindControl("CustomValidator2"), CustomValidator)  
        
                        If (item.OwnerTableView.IsItemInserted) Then 
        
                            imageValidator.ValidateEmptyText = True 
        
                        Else 
        
                            imageValidator.ValidateEmptyText = False 
        
                        End If 
        
                    End If 
        
                End Sub

but it didn't work bcoz the ClientValidationFunction still validating empty text in both cases. So i tried to modify this function to check if the item is in edit or insert mode using get_isItemInserted, but sth is wrong and i coudn't fix it. Here is my code

    
            function validateImageType(source, e)   
        
            {  
        
                e.IsValid=false;  
        
                var upload=$find(source.parentNode.getElementsByTagName('div')[0].id);            
        
                var inputs=upload.getFileInputs();  
        
                if (e.get_isItemInserted==true)  
        
                {  
        
                    for (var i = 0; i < inputs.length; i++)   
        
                    {  
        
                        //check for empty string or invalid extension  
        
                        if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value))   
        
                        {  
        
                            e.IsValid=true;  
        
                            break;  
        
                        }  
        
                    }              
        
                }              
        
                else 
        
                {  
        
                    if (inputs.length>0)  
        
                    {  
        
                        for (var i = 0; i < inputs.length; i++)   
        
                        {  
        
                            //check for invalid extension only  
        
                            if (upload.isExtensionValid(inputs[i].value))   
        
                            {  
        
                                e.IsValid=true;  
        
                                break;  
        
                            }  
        
                        }                    
        
                    }  
        
                    else 
        
                    {  
        
                        e.IsValid=true;  
        
                    }  
        
                }  
        
            }

And here is my column if nedded

    
                        <telerik:GridTemplateColumn HeaderText="Image" SortExpression="image" UniqueName="image" AutoPostBackOnFilter="true" DataField="image">  
        
                            <ItemTemplate> 
        
                                <img src='/Files/PhotoGallery/<%# Eval("image") %>' width="100" height="100" /> 
        
                            </ItemTemplate> 
        
                            <EditItemTemplate> 
        
                                <telerik:RadUpload ID="RadUpload1" runat="server" AllowedFileExtensions=".jpg,.jpeg" ControlObjectsVisibility="None"></telerik:RadUpload> 
        
                                <asp:CustomValidator ID="CustomValidator2" runat="server" ErrorMessage="Allowed file extensions are .jpg, .jpeg" ClientValidationFunction="validateImageType" Display="Dynamic"></asp:CustomValidator> 
        
                            </EditItemTemplate>

Using Telerik RadComboBox within a repeater

I have a repeater that contains a Telerik RadComboBox:

<asp:Repeater ID="rpt" runat="server">
    <ItemTemplate>
        <telerik:RadComboBox ID="rcb" runat="server" EnableLoadOnDemand="true"  
             AllowCustomText="true" ItemRequestTimeout="1000"
             NumberOfItems="10" MarkFirstMatch="false">
        </telerik:RadComboBox>
    </ItemTemplate>
</asp:Repeater>

In the ItemDataBound event of the Repeater, I am wiring up the ItemsRequested event like this:

private void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e) {
    RadComboBox rcb = (RadComboBox)e.Item.FindControl("rcb");
    rcb.ItemsRequested += rcb_ItemsRequested;
}
private void rcb_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e) {
    // Database call to load items occurs here.
    // As configured, this method is never called.
}

Currently, the server-side rcb_ItemsRequested method is never called. I suspect that wiring the ItemsRequested event in the ItemDataBound is problematic, but the problem may lie elsewhere.

Any ideas on how to use the Telerik RadComboBox within a repeater properly? I also tried wiring the event in the markup, but that did not help either. I am using the latest version of the ASP.NET AJAX Rad Controls.

[Solved] asp.net grid with RTL direction

Hello,

Before I purchase the controls, I make a small check if they support right to left.

I'm having a problem with RadGrid, in my MasterPage I must define the body direction to "RTL":
<body Direction="rtl">

Then i define in my grid <MasterTableView Dir="RTL">, as a result the filter window is open all over the page width.

Is there a solution to the problem?

Thanks in advance
