Thanks 

Hi all,

My problem is this: when I move a working radChart to a master/content page scenario the chart shows me the message 'there is no or empty series'. The same code works ok when I place it in a regular aspx page. I tried adding the RadScriptManager to the masterpage but that didn't work. I went through this forum and found a lot of posts on the masterpage problem but no solution to my problem, unfortunately. Here is the code

aspx page

and the aspx.cs page:

Anyone have any ideas why this is happening?

Thanks,

Peter

I have implemented a RadTabStrip and connected RadMultiPage.  The contents of each MultiPage are similar but have different purposes. 
For example purposes, let's say that the page contains the shopping list of a household for a given day where: Tab 0 = Fruit , Tab 1 = Vegetables, and Tab 2 = Dairy.

Each day the user will go onto the appropriate tab pages to enter the quantities of items purchased.  Some days all 3 tab pages will have data entered, other days there'll just be 2 of the 3 used, and still other days only 1 of the 3 will have anything recorded.

I've introduced logic so that the first of the 3 tab pages with any data on it will be preset when the user returns to review the data.  My initial investigation suggests that I must set the SelectedIndex property of BOTH the TabStrip AND the MultiPage, as in this example:

          RadTabStrip1.SelectedIndex = initialActiveTab;
          RadMultiPage1.SelectedIndex = initialActiveTab;

I wouldn't have thought that I need to do this as I thought the TabStrip and MultiPage were internally connected in a sense.  But I wanted to double-check here on the Telerik forums to be sure.

Hi Guys,

I have some problems of IE's Autocomplete suggestions.
The  IE's Autocomplete suggestions show in wrong position in child window when use RadWindow

Condition...
- The parent page have scroll

- When I open the RadWindow as an overlay and keep the position of overlay not go to top of parent's page the IE Autocomplete suggestions show wrong position. But if I move the overlay to the top of page by scroll up the IE autocomplete is shown the correct position.

How can I solve this problem?

Thanks in advance,
-Toi

Hello,

Currently I'm facing a small problem with the RadInputManager. Somehow when I call clientside an onSubmit on the RadInputManager my inputsettings are not validated / are not triggered. I'm still unable to find the problem what is causing this. Maybe there is a slight chance that you can provide me with an answer?

Declaration in javascript:
    // Validates the object data
    // @return void
    this.validate = function () {
        var result = true;

        // Get the input manager
        var inputManager = $find("<%=InputManager.ClientID%>");

        // Do already a submit to make sure that all validations are triggered
        inputManager._onSubmit();

        // Get the current settings of the input manager
        var settings = inputManager._getSettings();

        // Start validating all settings
        for (var setting in settings) {
            if (!this.validateInputField($find(setting))) {
                result = false;
                break;
            }
        }

        return result;
    };

    // Validates a input field
    // @param setting: The setting to validate
    // @return bool: True when the setting was valided successfully
    this.validateInputField = function (setting) {
        var result = true;

        for (var input in setting._inputs) {
            result = !setting._inputs[input]._invalid;

            if (!result) {
                break;
            }
        }

        return result;
    };

What am I doing wrong? :)
