Server Events?

Hi - I am very excited to use the RadTreeList as it will greatly simplify some existing code I created using RadGrid -- can you point me to a reference for Server Events (like Item DataBound) where I might be able to manipulate items? Documentation does not show server events..

Passing values in detail view to session variable

Heyas;

I thought I had a fairly straight forward thing going on, but it seems I'm stumbling over syntax. I am hoping someone can quickly clue me in so I can get this page knocked out. Basically, I have a grid with a heirarchy. In the detail view, there's a button that fires the "Select" command. When that happens, I need to get 2-3 data values from the selected record in the detail, and pass them to a variable for the next step. I know the code needs to go in the ItemCommand event, but I'm not sure on the syntax. Most of what I'm trying hasn't really met with much success, and I think it is because I am a little confused how the "bubble up" works when it comes to implementation.

Here's the relevant ASPX code:

<telerik:RadGrid ID="CreditsGrid" runat="server"

AllowPaging="True"

AllowSorting="True"

DataSourceID="SqlDataSource1"

GridLines="None" AutoGenerateColumns="False">

<MasterTableView

DataSourceID="SqlDataSource1"

DataKeyNames="OrderID">

<DetailTables>

<telerik:GridTableView runat="server"

DataSourceID="SqlDataSource2"

DataKeyNames="OrderID">

<ParentTableRelation>

<telerik:GridRelationFields

MasterKeyField="OrderID"

DetailKeyField="OrderID" />

</ParentTableRelation>

<CommandItemSettings ExportToPdfText="Export to Pdf" />

<Columns>

<telerik:GridBoundColumn

DataField="DateCreated"

HeaderText="Date Created"

SortExpression="DateCreated"

UniqueName="DateCreated"

ReadOnly="True" />

<telerik:GridBoundColumn

DataField="EnteredBy"

HeaderText="Entered By"

SortExpression="EnteredBy"

UniqueName="EnteredBy"

ReadOnly="True" />

<telerik:GridBoundColumn

DataField="ChargeCode"

HeaderText="Reason Code"

SortExpression="ChargeCode"

UniqueName="ChargeCode"

ReadOnly="True" />

<telerik:GridBoundColumn

DataField="Description"

HeaderText="Description"

SortExpression="Description"

UniqueName="Description"

ReadOnly="True" />

<telerik:GridButtonColumn

Text="Review Transaction"

ButtonType="LinkButton"

CommandName="Select"

UniqueName="btnRevTrans"

/>

</Columns>

</telerik:GridTableView>

</DetailTables>

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<CommandItemSettings ExportToPdfText="Export to Pdf" />

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn

DataField="DateCreated"

DataType="System.DateTime"

HeaderText="Date Created"

SortExpression="DateCreated"

UniqueName="DateCreated">

<HeaderStyle Width="175px" />

<ItemStyle Width="175px" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn

DataField="OrderID"

DataType="System.Int32"

HeaderText="OrderID"

SortExpression="OrderID"

UniqueName="OrderID">

<HeaderStyle Width="200px" />

<ItemStyle Width="200px" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn

DataField="NumOfOrders"

DataType="System.Int32"

HeaderText="# of Orders"

ReadOnly="True"

SortExpression="NumOfOrders"

UniqueName="NumOfOrders">

</telerik:GridBoundColumn>

<telerik:GridButtonColumn

CommandName="Select"

DataTextField="OrderID"

Text="View"

UniqueName="column">

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

And following area my feeble attempts on the vb.net side (I know the code is incomplete)

Private Sub CreditsGrid_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles CreditsGrid.ItemCommand

If e.CommandName = "Select" Then

'Put selected values to variables

Dim OrderID = CreditsGrid.MasterTableView.GetSelectedItems("OrderID")

Dim CreatedDate = CreditsGrid.MasterTableView.GetSelectedItems("CreatedDate")

'Removes session variables (just to be safe) & replaces with the new variables.

Session.Remove("OrderID")

Session.Remove("CreatedDate")

Session.Add("OrderID", OrderID)

Session.Add("CreatedDate", CreatedDate)

'Load Review form.

CreditsWindow.VisibleOnPageLoad = True

End If

End Sub

Obviously, this doesn't work so well. Can someone give me a pointer in the right direction?

How to get a ordered items list after drag

IE RadGrid Horizontal Scroll issue

Windows 7 x64, VS 2008, ASP.Net AJAX v 2010.2.826.35.

I'm auto generating RadGrids from the database using codesmith/nettiers and it works perfectly for some tables but doesn't for others. This particular issue only seems to be IE as it works in other browsers. It also happens whether there is data or not.

Bascially it gets confused with the position on the scrollbar and as you scroll right it can reset back to the left or as you reach the end of the table it loses track of earlier columns and just shows the last page with the scrollbar on the left and then last field with the scrollbar disabled.

If I drag the scrollbar to the right it continuosly moves left/right and occasionalyy I get an 'Unspecified Error' on:-

setTimeout(

"Telerik.Web.UI.Grid.frozenScrollHanlder("+this._frozenScrollCounter+")",0);

I think the issue is a problem with the column headers - below is a single column for a RadGrid that scrolls perfectly.

<telerik:GridBoundColumn DataField="LabourCardNumber" HeaderText="Labour Card Number" SortExpression="[LabourCardNumber]" HeaderStyle-Width="100px" HeaderStyle-VerticalAlign="Top" ItemStyle-VerticalAlign="Top" />

if I do something as simple as changing the HeaderText to "Labour Card Number Reference" the horizontal scrollbar no longer functions correctly in IE (6,7 or 8).

Think its something to do with the length of the HeaderText. Can you confirm its an issue and being looked into?

Thanks

Incorrect layout in Chrome and FF when grouping by Date

Hello,

To reproduce the issue open your demo in Chrome or FireFox.
http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourcegrouping/defaultcs.aspx

Then select
- Group by room
- Group by date
- Grouping direction: Vertical

Look at the left column. Unlike IE, these browsers display day of week and day number in the same column as the time. This leads to desync between column headers and the actual timeslots. If you scroll down, you may see that the gap between them is about a 0.5 cm!

HTML like strings in user input gives error

Hi All,
I have noticed a problem with the Grid inputs.
Given a normal Grid setup and a Bound string Column, a user hits Add and enters in the string :
<Test
Hitting save will yeild a framework error that starts with :
A potentially dangerous Request.Form value was detected from the client ...
This is not acceptable, as we have no control over user entry and we infact encourage the use of markup to format the inputs used later in forms. I realise that the use of an HTMLEditorColumn will in some way remove the problem for this field, but the risk still applies for all text inputs in grids.
What can be done about this? Can this error be trapped and dealt with client-side?
Will client-side scripting need to be implemented to "sanitise" the input before sending the request back to the server? If so, what rules do I need to apply to sanatise the data?
Thanks for your help,
Steele.

Change Highlight Color

Hello - I would like to customize the background color of a row when it's highlighted and selected. I've tried the following, but it only works a little.

When hovered, the background color changes, but an ugly gray border still exists along the bottom of the row. Also, when selected, my desired background color only shows up when the selected row is hovered, not all the time.

The ASP/CSS I'm using are below:

ASP for Grid:

<telerik:RadGrid runat="server" ID="rgReport">

<%-- Client settings --%>

<ClientSettings EnableRowHoverStyle="true" Selecting-AllowRowSelect="true" />

<%-- SelectedItemStyle settings --%>

<SelectedItemStyle BackColor="Black" />

<%-- MasterTableView Settings --%>

<MasterTableView AllowSorting="true" Caption="" Summary="" ItemStyle-VerticalAlign="Top" />

</telerik:RadGrid>

CSS for Grid:

tr.rgRow:hover, tr.rgAltRow:hover

{

background-image: none;

background-color: #E9E8D1;

border-bottom: 0px;

margin-bottom: 0px;

padding-bottom: 0px;

}

Please let me know what I can do... Thanks!
