Find ID of programmatically created RadGrid on Parent Page

Nevermind, I realized the child should not have access to the parent. I found another way of doing what I needed. Please delete this thread.

Dynamic hierarchy details

I'm trying to add/remove different sections from the NestedView details section based on some user selection made outside the grid.

The MasterTableView.NestedViewTemplate property does not seem to be stored in ViewState so I'm currently trying to set the MasterTableView.NestedViewTemplate in the PreRender with no success.

Does anyone have an idea how this might be possible?

PS. For efficiency my child data needs to only be databound when expanded.

Data formatting on calculated column

The data format string on my calculated columns is not functioning. I've tried a variety of different format strings, including the same dataformatstring I use on the data bound columns, "{0:N0}", but on the calculated column ( a simple ratio of two of the data bound values) the grid displays all the decimals.

Any special trick for assigning a data format to a calculated column?

[Solved] set selecteditem background color none

I am using radgrid and GridClientSelectColumn. When I select a row, the row is highligted with gray color. I guess thats like default skin. How I can set the selected row background color to none. I just want to be able to check the box and uncheck with no background color for the row.

Do I have to use onRowSelecting or onRowSelected event? If so, how can I get the selected row item on the clientside.

Hierarchical binding to ObjectDataSource (Exhausted!)

Hi everyone,

Let me start by apologising for this question - despite being a competent VB6 programmer, I'm new to .NET and am aware that this question is the sort of one that would probably cause sniggers at the back of the class-room.

I'm trialling ASP.NET RadTools AJAX which I must say looks tremendous. I am slowly trying to get it to replicate the functionality I need before deciding on the direction to take to migrate some aging systems.

I don't normally post for help (I can normally work stuff out) but after spending two solid days piecing together various examples I can honestly say I'm stuck.

I am trying to create a RadGrid that allows me to drill down on related tables. I've seen various examples which include SQL markup within the actual page - but I'm trying to use an ObjectDataSource pointing to a SQL DataSet. This is to centralise the SQL markup making maintanence a tad easier.

My Main table is a table called LanSubnet with a PK of LanSubnetID and a FK of SiteID

The "drill down" table is called Site - with a PK of ID. The association between the two is "LanSubnet.SiteID=Site.ID"

So when someone drills down on a specific item, it shows all the associated sites - simple eh?

I'm trying to achieve this without coding - although if that is the only way, then so be it (I prefer VB.NET). My attempts either cause the details table to show all sites, or show none. I can't get it to only show the ones associated with the chosen master table and I've not got a clue why?

The SQL for LanSubnet is this:

SELECT LanSubnetID, SiteID, StartIP, EndIP, NTDomain, AdminUserName, AdminPassword, SNMPCommunityString, AuditStartDate, AuditFinishDate, AuditDevicesFound, AuditDevicesFailed, LastUpdatedUserID FROM dbo.LanSubnet

The SQL for the details (Site) table is this:

SELECT ID, CompanyID, PrimaryEmployeeID, Name, Description, [Address 1], [Address 2], County, [Post Code], [WWW Map Page], [Phone Number], [Fax Number], ScheduleNotes, Directions, [Local Station], IPaddress, OldData, Created, tmpSiteID, tmpCompanyID, longitude, latitude, Modified FROM dbo.Site WHERE ID=@SiteID

I'm attempting to pass to it @SiteID which will fix the issue! I'm assuming the GridRelationFields will filter the results? I've been trying to get it to work in the same way I got a drop-down to work?

As a side question - any suggestions what I should be reading to get my head around binding in general?

Many thanks in advance.

Here is my code:-

Sorting problem "Column Not found"

I am binding the RADGrid to a collection of business objects. These business objects implement an interface, that inherits another interface.

When I am trying to sort (or do any other operation) on a column bound to a property, that only exists on the base interface, I get this exception:

[IndexOutOfRangeException: Cannot find column ItemNumber.] 
   System.Data.DataTable.ParseSortString(String sortString) +4826462

How do I get around this issue ?

This issue arises if I try to bind to IItemInterface instances and sort on the ItemNumber column, where IItemInterface is declared as follows:

                        public class Item : IItemInterface         
                {         
                    public string Name { get; set; }         
                    public string ItemNumber { get; set; }         
                }         
                     
                public interface IBase         
                {         
                    string ItemNumber { get; set; }         
                }         
                     
                public interface IItemInterface : IBase         
                {         
                    string Name { get; set; }         
                }         

Thanks for your help,

RAD Grid and DataList

Hi Guys,

I have a Grid that shows catagories and I have set up a NestedViewTemplate that comprises of a DataList (this datalist basically contains checkboxes). what I want to do is bind the a datalist programmatically.
That is I need to get the items of the expanded catagory and fill it up on the checkboxes of the datalist. How can I do this?, and also I should be able to read the checked values back.
Can someone help me on this?
