How to access a value inside an array in RadGrid ?

I have an array bound to RadGrid.
I can use the <%#Eval method to get the values in the root of the array in the aspx file. However, there is one particular value which is inside an array where I do not know how to get it.

eg of the array structure
customername   Michael
    customerdetails
         specialremarks   xxxxxxxx

How can I get the value for specialremarks ?

I tried the itemdatabound but to no avail.

Any help is much appreciated

Thank you

Styling nestsed table in RadGrid

Hi Team,

I have a radGrid with a nested table which contains radList View and I have to style it as shown in the attachment(Nested_Table.jpg), here i can have multiple rows selected/active/expanded at one point of time.
I am facing 2 issues right now
1. I am a able to use rgSelected class to style the selected row but dont know how style the row which is nested below as shown in(Nested_Table_1.jpg)
2. When multiple rows are expanded if i select a row manually the other two rows are losing the style as shown in (Nested_Table_2.jpg)

the skin i am using for this is

<rad:RadGrid runat="server"

SkinID="CSFSelectionGrid"

HeaderStyle-Wrap="true"

ItemStyle-Wrap="true"

AlternatingItemStyle-Wrap="true"

AllowFilteringByColumn="false"

EnableEmbeddedSkins="false"

EnableEmbeddedBaseStylesheet="false"

GroupingSettings-CaseSensitive="false"

CssClass="SimpleGrid"

ImagesPath="~/Skins/Plain/Grid"

AllowMultiRowSelection="true" >

<ClientSettings AllowColumnsReorder="False" ReorderColumnsOnClient="False" AllowExpandCollapse="True">

<Selecting AllowRowSelect="True"/>

<Scrolling AllowScroll="false" UseStaticHeaders="True"/>

</ClientSettings>

<MasterTableView AllowNaturalSort="false" AllowCustomSorting="true" >

</MasterTableView>

</rad:RadGrid>

and the class changes are

.SimpleGrid .rgSelectedRow td,

.SimpleGrid .rgSelectedRow td.rgSorted

{

background-color:#b0c5da;

border-bottom:1px solid #ccc !important;

}

and the server code is

protected void RequestCSFs_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.ExpandCollapseCommandName && e.Item is GridDataItem)

{

((GridDataItem)e.Item).ChildItem.FindControl(NESTED_VIEW_TEMPLATE_PANEL).Visible = e.Item.Selected = !e.Item.Expanded;

}

Please suggest me how to achieve the desired result.
Thanks,
Preetham

[Solved] JS error when using setActive

Hi,

I have got a problem when using the setActive Javascript function on a RadWindow. The error is :
"Sys.ArgumentNullException: Value cannot be null.Parameter name: element".

I don't understand why the parameter is null. The parameter corresponds to oWnd._popupElement.

May anyone help me fixing this error ?

Below is an extract of the Javascript code that generates the exception :

// 1) User-code file, launched at body:onLoad() event

var oWnd = $find("helpWindow");

oWnd.setSize(400,500);

oWnd.setActive(false);

// 2) Telerik code file

setActive:function(c){var f=this._popupElement;

if(!c){Sys.UI.DomElement.addCssClass(f,"rwInactiveWindow"

); // f is null

[...]

// 3) Microsoft ASP.Net Ajax code file

Sys.UI.DomElement.addCssClass = function Sys$UI$DomElement$addCssClass(element, className) {

/// <summary locid="M:J#Sys.UI.DomElement.addCssClass" />

/// <param name="element" domElement="true"></param>

/// <param name="className" type="String"></param>

var e = Function._validateParams(arguments, [

{name: "element", domElement: true},

{name: "className", type: String}

]);

if (e) throw

e; // The exception is thrown here

if (!Sys.UI.DomElement.containsCssClass(element, className)) {

if (element.className === '') {

element.className = className;

}

else {

element.className += ' ' + className;

}

The RadWindow that is used is described in the following aspx code-file :

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"

ReloadOnShow="true" runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="HelpWindow" runat="server" NavigateUrl="Help.aspx"

ReloadOnShow="true" VisibleOnPageLoad="false" ShowContentDuringLoad="false"

Behaviors="Close, Maximize, Resize" Width="500px" Height="400px" Modal="true"

Animation="Fade" KeepInScreenBounds="true" RestrictionZoneID="form2" AutoSizeBehaviors="Height">

</telerik:RadWindow>

"Auto-generate edit column at runtime" and "auto-generate delete column at runtime" problems

Hello,

I have checked the choices "auto-generate edit column at runtime" and "auto-generate delete column at runtime" to the "rows drag and drop shipped orders datagrid". i' m trying to write the corresponding events so as to give functionality to the edit and delete link buttons. How could i catch these events (i can't catch them with ItemCreated and ItemCommand events). Could you please give me some help?

Also, when i set to EditMode the value InPlace i can't see the "cancel link button" and a part of "insert link button" when i press the "Add new record" button.

Thank you very much.

treeview expandDepth

Hi, I am new to Telerik. In standard MS treeview, there is a property "Expand Depth". On the first load, the treeview will expand to the level you set in expand depth. What is the equivalent property in RadTreeview? Or how can I achieve that behavior?

I bind the RadTreeview to a datatable. I modified my query to to limit the dataset to only first two levels of nodes. By doing that, however, I lost the little plus sign in front of the low level nodes. So, I can't expand it via server side load-on-demand.

Thank you in advance for your help!

excel export formatting

hello,

i am using the export to excel feature of radgrid. i need to add some formats to specific cells which should also be exported:

1. setting back-color of certain cells based on the data -> i want to mark the best %-value of the cells in one row but not in every row.
if i set the backcolor of the cell it has no effect on the export. i found some solutions how the set the style at export but i need this also when viewing the grid online. how can this be accomplished without implementing it twice? where should i put the code and how can i access the data needed to decide whether to set the back color or not.

2. setting a thicker border to certain areas:
i found some old forum posts to alter the border but this has an effect to all borders. i need to set some thick borders around certain areas also based on data/structure. during creating the data for my grid i could save the row and column information i need and later i would like to set the border around rows 2-5 and cell 0-10 for example.
the grid exports the usual grid lines (border=1 and black) which should stay as it is.

hope someone can help me out on that

regards

Grid

ExpandedImage is not shown if node has no childs

Hi,

is it possible to display the ExpandedImage of a node, even if the node has no childNodes (is empty)?

At the moment there is a plus sign in front of a node before you expand it.
If you expand a node which is NOT empty there will be a minus sign,
but if you expand a node which is empty there will be no minus sign (only the lines).

Is there any attribute to change this behaviour?

thank you!

Dismiss cannot rebind RadScheduler

Hi,

I have an update panel in that i have "RadScheduler" and other controls...

I have added one Appointment with "Reminder" of 5 min. as well as daily "Recurrence" as every 1 day...

Now "Reminder dialog" displayed and i press "Dismiss" it will trigger ReminderDismiss event than AppointmentUpdate and finally AppointmentInsert events

In dismiss event i have just add code that update Reminder field in database...
In AppointmentUpdate event i have just updated RecurrenceRule with Exceptions Date that will add "SU EXDATE" to RecurrenceRule...
In AppointmentInsert event i just add new Simple Appointment same as previously added appointment but with no RecurrenceRule. So the Recurrence start from next day and today will be excluded.

For Rebinding Appointments from database, In AppointmentInsert event i added the code to Rebind data. But, it will not effect on RadScheduler and when click on edit/delete it ask for "this occurrence or series to Edit/Delete?". However when i click other linkbutton or button from the page, it will Rebind RadScheduler and Scheduler and updated as i want.

I have tried Response.Redirect in AppointmentInsert event but it shows me error because of CallBack event. So i thought that if it is CallBack event RadScheduler can not able to rebind. Even i can not change any element of aspx page.

So if possible i want to know after all event Called (ReminderDismiss->AppointmentUpdate->AppointmentInsert) when dismiss pressed, In which event i suppose to do Response.Redirect or RadScheduler Rebind() / Databind() ... ?
