What control could I use to represent deep hierarchy structure?

I'm going to build a hierarchy structure. Each layer contains about 12 columns and in total I'll have 7 layers of hierarchy.

I have used RadGrid Hierarchy nested table features on some of the pages which had 1-2 nested tables and it works fine, however, on this page because mainly there are 7 layers of hierarchy I can't use RadGrid Nested Tables as the 7th Nested table gets opened in the middle of the page in that case!

What other control could I use to represent such structure?

E.g. Master Detail View, not sure?

Thanks,

Selection problem

Hi! I have tried to understand grid basics by following the demos in the website but i can't get the selection right. I'm trying to select an item by selecting a row (i'm not sure that is possible), and i even tried to creat a column (GridButtonColumn) where i set the button as image button and the imageurl for the image i want but i can't get it right, cause it is always appearing a checkbox instead of the image and, althought it selectes the row it does not selects the item in the row (i put a breakpoint in the grid_SelectedItemChanged and it doesn't do anything).
I also tried to do this as an gridtemplatecolumn and it makes appear the image i want but every time i click on it, instead of selecting the row and the item, it gives me an error witch i don't really know whatit means.

Code for the gridButtoncolumn (and grid):

<telerik:RadGrid runat="server"

FilterControlAltText="Filter quando column" HeaderText="Criado/Alterado"

SortExpression="quando" UniqueName="quando">

</telerik:GridBoundColumn>

</Columns>

One more thing, i only know vb.net and not very much. I can handle html so if possible and the solution calls for code i would appreciate for it to be in vb.net, if is as to be in c# or javascript so be it.

Thanks,
FEST

What event do I need to use to insert child records in a grid?

As a follow up to the earlier question beneath, I'm trying to write some code to assign contacts to facilities.

http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-reference-parent-data-items-in-edititemtemplate.aspx

I'm following samples such as the one beneath but I'm unable to find the correct event that I need to use. I'm currently trying to use 'RadGrid1_InsertCommand' but I imagine that's not working because it's the event that would be used for inserting the parent 'Facilities'.

http://www.telerik.com/community/code-library/aspnet-ajax/grid/automatic-operations-in-hierarchical-grid-with-sqldatasource-control.aspx

Can someone tell me what event I need to be looking at?

Thanks,
Tim

Protected Sub RadGrid1_InsertCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)

'This event is not firing when I click on the 'Insert' link. What event do I need to use instead?

Dim insertedItem As GridEditFormInsertItem = DirectCast(e.Item, GridEditFormInsertItem)

Dim parentItem As GridDataItem = e.Item.OwnerTableView.ParentItem

Dim datakey As String = parentItem.OwnerTableView.DataKeyValues(parentItem.ItemIndex)("FacilityID").ToString()

Dim contactId As Integer = (TryCast(insertedItem("colContactId").Controls(0), DropDownList)).SelectedValue

Dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)

Try

conn.Open()

Dim insertQuery As String = "INSERT into FacilityContacts(FacilityId, ContactID) values('" & datakey & "','" & contactId & "')"

Dim cmd As New SqlCommand(insertQuery, conn)

cmd.ExecuteNonQuery()

conn.Close()

Catch ex As Exception

RadGrid1.Controls.Add(New LiteralControl("Unable to insert contact. Reason: " + ex.Message))

e.Canceled = True

RadloadingPanel slow over RDP

2011 Q2, the default loading panel that blocks the entire grid when grid is refreshing takes a long time over RDP beause it paints each line by line of the "block".

Is there a way to optimize this behavior other than changing the loading panel for all? When viewing over LAN it's fine.

IE8 is noticeably slower than FF5.

Newline in Radcomboboxitem

I'm populating information from a webservice into a radcombobox in asp.net. I would like to force a line break for certain items to clean up the dropdown information.

No matter what I put in the text field, it always just renders the text and never actually creates a line break. I looked into creating an itemtemplate for the combobox, but from what I've read, it's not worth the effort when using a webservice.

Is there an escape character that I could use to force a line break?

Thanks,
Javier

RadToolTip not showing on RadGrid field?

I have a RadGrid where I'm truncating the display of cell data in order to preserve page real estate. I want to show the full cell content in a RadToolTip.

On the server, in the GridItemDataBound server-side event handler, I'm transforming the values of each cell for display. On the client, I'm truncating the display data using text-overflow:ellipsis. On the server, I'm creating a RadToolTip with the full value, and shoving it into the Page object's Controls collection:

var item = (GridDataItem)e.Item;
var cell = item["Flavor"];
cell.Text = reallyLongFlavorNameValue;

var tooltip = new RadToolTip();
tooltip.Title = "Flavor";
tooltip.Text = reallyLongFlavorNameValue;
tooltip.TargetControlID = cell.ID;
tooltip.IsClientID = false;
tooltip.RelativeTo = ToolTipRelativeDisplay.Element;
this.Controls.Add(tooltip);

I'm assuming the rest of the values can be defaults.

However, when I show the page, the tooltip never shows.

What am I missing?

Thanks

Features of SP2010 SAK

Hi. A few questions about the Sharepoint Acceleration Kit:

In the regular editor available in Sharepoint 2010, when we choose to insert an image in a page, there's no easy way to choose an image from the "Site Assets"; we have to upload the image every time from our computer or copy/paste the image URL. Does the SAK tool provide an easy way to choose an image from the Site Assets (or other library)?
I've read that the CTP will move to a final release later this year. Is that true?

Thank you :)

first firing itemcommand and sort to default state

Hi,

I'm having some small problems with RadGrid.

Issue 1:
Here is an example page
http://dev2.spireweb.no/resultat.aspx?pid=15&rb=1&type=simpel&q=test
When I fill in a value in the textbox the first time and then I click "Kjøp" then it does not find the value of the textbox, and just add 1 item to cart (handlevogn), but the second time I click "kjøp" it finds the value enter in the textbox.
Here is my ItemCommand code:

protected void radResult_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

switch (e.CommandName)

{

case "AddToCart":

int test = e.Item.DataSetIndex;

TextBox txtQuantity = (TextBox)(e.Item.FindControl("txtQuantity"));

if (txtQuantity.Text.Length > 0)

ShoppingCart.GetCurrentUsersCart.AddItem(int.Parse(e.CommandArgument.ToString()), int.Parse(txtQuantity.Text.ToString()));

else

ShoppingCart.GetCurrentUsersCart.AddItem(int.Parse(e.CommandArgument.ToString()), 1);

txtQuantity.Text = "";

RadAjaxManager1.ResponseScripts.Add("javascript:updateCart();");

//RadAjaxManager1.ResponseScripts.Add(string.Format("alert('Hello from the server! Server time is {0}');", DateTime.Now.ToLongTimeString()));

break;

}

Why do this happen?

Issue 2:
Who can I "reset" the sort, so it goes back to first sort state?
Here is an example page:
http://dev2.spireweb.no/resultat.aspx?pid=15&rb=2&type=simpel&q=test
If I click "Vis treff A-Å" how can I go back to the sort state the radgrid started with?

Thanks in advaned...
