When trying to use the RadGridDesigner with the grid webpart I get a 403 error. When I look at the event viewer application log I see the following error. Not sure how to fix this.

WebHost failed to process a request.

I have a grid that invokes the edit appointment functionality, but on an appointment that is a series, I'd like show the Edit occurence/series dialog option from server side.

  this.radActivity.ShowAdvancedEditForm(apptToEdit, true);             

I've made a RadGrid with EditMode="Batch" that is bound to a dataset. I need to create some GridTemplateColumns, such as the above. 3 questions...

1) In checking out examples online, at times I've seen Eval above as it is...

Text='<%# DataBinder.Eval(Container.DataItem, "Quantity") %>'>

...but other times like this...

Text='<%# Eval("Quantity") %>'>

The latter is cleaner, but wondering if the first is recommended for some reason. Or are they identical?

2) Also, at times I've seen in the GridTemplateColumn header the attribute DataField and DataType, such as...

DataField="Quantity"

DataType="System.Double"

... but again, not always. Are they necessary? Or does it depend on the situation?

3) Do I need to somehow Bind the field to the EditItemTemplate portion?

Thanks for the help!

Like in Total Commander that user can navigate back by clicking in folder name in breadcrumb?

thanks

Hi,
I am using the radinput manager with the "<Validation IsRequired="True" />" property to force certain textboxs to be required.

This works well displaying a warning symbol on the relevant textbox and a red outline if the box is left empty.

My issue is I also have a combobox with a required field validator, but this doesn’t indicate the input has no value selected in the same style as the other textbox controls giving an inconsistent interface.

Could this functionality be added to the standard combobox (obviously only IsRequired functionality) or full functionality if using a RadCombobox as this effectively contains a textbox.

Hi

Hello Everyone,

Can anyone suggest how to highlight the dropdown options upon mouse over. By default, I see a grey color highlighted when I hover on any of the options in the Dropdownlist. Please refer to the screenshot attached.

I would like to change the default color (grey) and give some brighter color for more visibility. 

ASP.NET version - Visual Studio 2013 Version 12.0
OS - Windows 8
exact browser version - IE >= 10
exact version of the Telerik product = 2009.1.527.35
preferred programming language = C#

Thanks in Advance!!

Browser - safari version: 9.0.2 (11601.3.9)

I have a combobox, which uses treeview to show the data. 
When I click on combo box I get the following error

hi

I am applying a background color to all grid using this;

<style type="text/css">
      .RadGridHeaderStyle
        {
            background-color:#5e9cd2 !important;
            background-image:none !important;
            font-weight:bold !important;
            color:white !important;
        }

</script>

The header background color work fine but the font color on some columns don't seems to apply. I realised that it is because the column is sortable and the color won't change to white. How should make the sortable header font color to white? Thanks
