[Solved] Problem with binding Rad Grid using Microsoft Enterprise Library 5.0

Hi There,
I've upgrade my project to Microsoft Enterprise Library 5.0 (former version was 4.1) but I got a runtime error when the Rad Grid is binding.
My code is something like below:

    
            public static IDataReader GetAllOrders()   
        
            {  
        
                SqlDatabase db = new SqlDatabase(connString);   
        
                return db.ExecuteReader("Orders_GetAll");   
        
            }  
        
            protected void Page_Load(object sender, EventArgs e)   
        
            {  
        
                shopGrid.DataSource = DataProvider.GetAllShopOrders();   
        
                shopGrid.DataBind();  
        
            }

End I get this error:
Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.

I didn't have this problem with Microsoft Enterprise Library 4.1 or lower.

[Solved] Fetching user control with Rad Controls using web service

Hi.

I have a user control which has a repeater. Each row of the repeater has three columns containing a control each

1st column - ASP label control
2nd column - Rad Combo Box
3rd column - Rad Text Box

This user control has a public property that accepts the data to be bound to the repeater control.

I want to achieve the following.

On the main web page, on a click of button, using a web service i want to get the HTML content of the above user control.

In web service, I create an instance of Page, dynamically load the above user control, add it to the page, get the HTML of page
and send that HTML as a string to the requesting web page.

The above thing works if I don't have Rad Controls in the user control. If I use generic HTML controls or asp controls (that don't require scriptmanager) it works perfectly fine. But there are Rad Controls, when I try to get the HTML of the page by calling RenderControl I get an error saying 'ScriptManager' needs to be present.

Is there an alternate way to circumvent the problem?

Thanks.

Custom Properties for Dynamically created RadWindow from Code Behind

Hi,

I am creating windows dynamically based on the settings I retrieve from database. Need to add some custom properties to the RadWindows so that I can use them while rendering to make decissions, like whether to show it in the minimized mode after its visible(because I've many rad windows popping up on the screen). Attributes which will drive the minimum width and height of the windows, which I'll use in the resize event of the RadWindows.

I've a code sample here, kindly help me understand how I can do this.

Data entered in a rad window is lost when another radwindow is opened on top of that.

Hi,

I have a rad window, in which I have a grid view whose data is bound on the itemdatabound event and a button .

On Click of the button, I have certain validations done and open another rad window on top of my first radwindow.

The second rad window has a label and a button on click of which it closes.

When the second rad window closes, I can see that the data in the grid view disappears and the message that I have in the <EmptyDataTemplate> of the gridview will be dispalyed in the first radwindow. Basically data binding is not happening.

This happens even when I have a repeaer control in my first radwindow.

How do I overcome this issue?

Thanks & Regards,
Shruthi N

MasterTable not rendering in multipage

Hello Telerik team,

I have a problem with multiple RadGrids in separate PageViews of a RadTabStrip/RadMultiPage control set

Here is the setup and the problem follows:

1. I have a RadTabStrip and a RadMultiPage connected by the MultiPageID property.

2. This Tab is part of a table that is part of a Panel that is initially not displayed (style:display: none")

3. All of this is contained is an MS Update Panel

4. There are 10 tabs.

5. On 4 of the tabs, I have a RadGrid created on the PageView for each of the 4 tabs

*** HOWEVER** Since I am doing client-side data binding, these grids do *NOT* bind when the page first loads (IsPostback = false)

6. I have implemented the OnCommand client side event for each of the Grids (However, they do not seem to fire when the page renders)

The problem:

- The user selects a function and the client displays the hidden panel.

- The user selects one of the Tabs that has a grid

- The client code fires an ADO.Net data service that returns the data to the browsre

- The DataService callback cannot locate the MasterTables because they have not been rendered

Can you help me figure out why the master tables do not render on the initial page load?

HINT: If I load the page and then immediately do a full browser page refresh, the tables *WILL* render !?!?!?!?!?

Thanks

Bob
