[Solved] Adding aggregates programmatically

I have a page with one radgrid on it. This page contains different sets of columns depending on how the user gets to the page. In all cases the grid offers Grouping. Since I cannot declare the columns ahead of time and I allow the user to group by whatever he/she chooses, how can i get specific columns to show aggregates in the group footers when grouping is active?

I can get footers to contain text by doing something simple like:

    
                Protected Sub Radgrid_ItemDataBound(ByVal source As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound  
        
                    If TypeOf e.Item Is GridGroupFooterItem Then  
        
                        Dim footer As GridGroupFooterItem = e.Item  
        
                        Try  
        
                            footer("ReworkCosts").Text = "Sum of Rework Costs: $" 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("MaterialCosts").Text = "Sum of Material Costs: $" 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("ScrapCosts").Text = "Sum of Scrap Costs: $" 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("DefectCosts").Text = "Sum of Defect Costs: $" 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("QNote").Text = "Count of Qnotes: " 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("MRCs").Text = "Count of MRCs: " 
        
                        Catch ex As Exception  
        
                        End Try  
        
                        Try  
        
                            footer("SCARs").Text = "Count of SCARs: " 
        
                        Catch ex As Exception  
        
                        End Try  
        
                    End If  
        
                End Sub

...but I don't know how to access all of the items in a specific column of that group so that I can add/count them and concatenate themm to the end of my string.

Any recommendations?

I am using VB.NET, .NET 3.5

Something that should be so simple...

So what I'm trying to do should be very basic, but seems unnecessarily difficult with the radgrid. All I am doing is binding the grid server-side, and need to conditionally set a column to "readonly" if certain criteria is met by the item's dataitem. So my question is how do you set a single item's column to readonly in the ItemDataBound event?

    
            protected void gridFavorites_ItemDataBound(object sender, GridItemEventArgs e) 
        
                { 
        
                    if (e.Item.DataItem != null) 
        
                    { 
        
                        IFavorite fav = (IFavorite)e.Item.DataItem; 
        
                        if (fav.CmsPageId == Guid.Empty) 
        
                            // Where to go from here to set readonly=true? 
        
                    } 
        
                }

RadGrid as data entry form?

Hey all,

I want to use a radgrid without a data source, just to be able to for my customers to enter in line items for creating invoices. I want it to be able to add rows by using ajax, and then loop through after the data entry and insert to my sql db... i cant seem to figure out how to use the grid by default to be a data entry form rather than a data display form.

[Solved] Clientside row select - w/o set_selected()

Hi

Is there a way to set the display of a grid row to look as if it is selected without using set_selected()?

I have a grid which I am populating on the client. When the user selects a row, I am populating other controls via a RadAjaxPanel (therefore a postback). When the control finishes the postback, the row is no longer selected, so I am storing the index of the row that was selected and during the RadAjaxPanel_OnResponseEnd, I am attempting to reselect the row using set_selected. Works great, except that that fires the event which is causing an indefinite loop of postbacks.

I was hoping that there is a way on the client to set the style of the row to look selected without using set_selected(), hopefully avoiding the problem described above.

This gets me my selectedrow (on the client)

    
            $find("<%= grdEntityAttributes.ClientID %>").get_masterTableView().get_dataItems()[document.getElementById("selectedRow").value]

Any ideas?

How to set up new opened IExplorer window called from RadGrid Hyperlink column

Hi,

I have a RadGrid with an Hyperlink column that when clicked opens a new IExplorer window that shows a web page with information related to the row.

I want to control what the new opened IExplorer window shows. Like hide the menu bar, status bar, enable/disable resizing and the like.

I understand that the way to go is using javascript function window.open(). Now since I am using the RadGrid Hyperlink column with the property "Target= _blank", my question is:

Where I suppoese to inser the javascript string to call the new window set up as I want it?
or
Is there any other method or best practice to accomplish this in the context of Telerik RadGrid component?

Any advice would be appreciated.

[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.

RadEditor doesn't support Image Links

It only supports document linking.

Kindly include image link where in the dialog, you can select the image file to link.

Other editors have this functionality, but RadEditor lacks.

Thank you.
