I am testing the ajax controls for a possible migration and I have a couple of doubts about the radgrid and raddosck

We are developing a dashboard screen that displays a differents panels. Some of the panels display charts and graphs, while others contain tables with aggregated data.

There is a lot of information being displayed on this page.

We want delay loads for each panels instead of waiting until all of the data for all of the panels has been processed before serving the page.

We´re using SqlDataSource to provide all the data, not webservice.

Now we use GridView a litle trick http://mattberseth.com/blog/2007/07/delay_load_an_updatepanel.html

Can we do this with radgrid and raddosck?

Thanks in advance

set Attribute from client side doesn't work on server side

I am setting custom attributes value from client side in batch edit event like this:

///below function call when grid go to edit mode to view mode and below code for set from list box value to grid cell value.

function GetEditorValue(sender, args) {

debugger;

if ($(args.get_cell()).find(".RadListBox").length > 0) {

var lb = $find($(args.get_cell()).find(".RadListBox").attr("id"));

var item = lb.get_selectedItem();

if (item != null) {

args.set_cancel(true);

args.set_value(item.get_text());

var cell = args.get_cell();

cell.setAttribute("searchboxresult", item.get_value());

//args.set_value(item.get_value());

} else {

args.set_cancel(true);

args.set_value("");

}

Here I have set attribute value of searchboxresult to specific value which you can see here:

<td searchboxresult="109" style="width:200px;" class="rgSelectedCell rgBatchChanged">

<div style="">Headlights - Dual-Beam</div>

</td>

Now When I try to access this attribute at my server side on BatchEditCommand like this:

protected void accoADEGrid_BatchEditCommand(object sender, GridBatchEditingEventArgs e)

{

foreach (GridBatchEditingCommand command in e.Commands)

{

var i = command.item.cell[9].Attribute["searchboxresult"].ToString();

}

I am getting value of i = 0; which is not as per client value and getting unchange value of attribute which is set on ItemDataBound.

radgrid injecting height of 10px

I have an issue where I have a popup window (windowmanager has height/width that are explicit, is a modal).

This popup contains a html table. One tr is 20% wide, other is 80%.

I have a grid in the 20% wide side (left side) and in IE and Chrome it is fine, but in firefox, the .rgDataDiv class is injecting a height of 10px. In IE and Chrome, the value gets calculated fine.

No ajax. Any ideas?

Changing AllowScroll="true" to "false" fixes the issue but I want the autoscroll to be true.

<table style="width: 100%; height: 88vh; border-spacing: 0; border-collapse: collapse; border: 0">

<tr>

<td width="20%">

<RadGrid

ID="PayrollProcessSummaryGrid"

runat="server"

GridLines="None"

Height="100%"

AutoAssignModifyProperties="true">

<ClientSettings AllowColumnsReorder="false" ReorderColumnsOnClient="false">

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

<Selecting AllowRowSelect="true" />

<ClientEvents OnRowClick="onRowClick" OnGridCreated="onGridCreated" OnCommand="onCommand" />

</ClientSettings>

<MasterTableView

AutoGenerateColumns="false"

CommandItemDisplay="Top"

AllowSorting="false">

<CommandItemTemplate></CommandItemTemplate>

<Columns>

<wasp:GridDateTimeControl DataField="field1" LabelText="*field1*" SortExpression="field1" niqueName="field1" />

<wasp:GridDateTimeControl DataField="field2" LabelText="*field2*" SortExpression="field2" niqueName="field2" />

</Columns>

</MasterTableView>

</RadGrid>

</td>

<td width="80%">

<telerik:RadSplitter ID="RadSplitter" runat="server" Orientation="Horizontal" Height="100%" Width="100%" VisibleDuringInit="false" OnClientLoad="onClientLoad" BorderSize="0">

<telerik:RadPane ID="RadPane" runat="server" Width="100%" />

</telerik:RadSplitter>

</td>

</tr>

the server method '' failed

Hello

I am using a web service like the demo to populate the items in the RadComboBox on demand. This is all working find when i am running the program through VS2010 but is failing when I try through IIS.

Also it works for Http and does not work for Https so I think the solution lies there somewhere.

Here is my .aspx:

<telerik:RadComboBox AutoPostBack="true" ID="txtGelPackProdCode" runat="server" EnableLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true" EmptyMessage="Enter here..." onselectedindexchanged="txtGelPackProdCode_SelectedIndexChanged">

<WebServiceSettings Path="MasterFormulaWebService.svc" Method="LoadProductData" />

</telerik:RadComboBox>

this is the svc method:

public RadComboBoxData LoadProductData(RadComboBoxContext context)

{

string text = context.Text.Trim() + '%';

DataTable data = ProductDAO.ViewData2(text, "RadCombo");

List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(context.NumberOfItems);

RadComboBoxData comboData = new RadComboBoxData();

try

{

int itemsPerRequest = 10;

int itemOffset = context.NumberOfItems;

int endOffset = itemOffset + itemsPerRequest;

if (endOffset > data.Rows.Count)

{

endOffset = data.Rows.Count;

}

if (endOffset == data.Rows.Count)

{

comboData.EndOfItems = true;

}

else

{

comboData.EndOfItems = false;

}

result = new List<RadComboBoxItemData>(endOffset - itemOffset);

for (int i = itemOffset; i < endOffset; i++)

{

RadComboBoxItemData itemData = new RadComboBoxItemData();

itemData.Text = data.Rows[i]["prod_code"].ToString().Trim();

itemData.Value = data.Rows[i]["name"].ToString().Trim();

result.Add(itemData);

}

if (data.Rows.Count > 0)

{

comboData.Message = String.Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", endOffset.ToString(), data.Rows.Count.ToString());

}

else

{

comboData.Message = "No matches";

}

catch (Exception e)

{

comboData.Message = e.Message;

}

comboData.Items = result.ToArray();

return comboData;

}

and this is the webconfig:

<system.serviceModel>

<behaviors>

<endpointBehaviors>

<behavior name="Reena.Master.MasterFormulaWebServiceAspNetAjaxBehavior">

<enableWebScript />

</behavior>

</endpointBehaviors>

</behaviors>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"

multipleSiteBindingsEnabled="true"

/>

<services>

<service name="Reena.Master.MasterFormulaWebService">

<endpoint address="" behaviorConfiguration="Reena.Master.MasterFormulaWebServiceAspNetAjaxBehavior"

binding="webHttpBinding" contract="Reena.Master.MasterFormulaWebService" />

</service>

</services>

<bindings>

<webHttpBinding>

<binding name="webBinding">

<security mode="None">

</security>

</binding>

</webHttpBinding>

</bindings>

</system.serviceModel>

What am I doing wrong? Thanks

How to export data from Context Menu to a text file

I am showing a RadTreeView on my page and it has a context menu associated with each node. When you right click on any node, an option is displayed called "Export". This export will run a stored procedure and bring data from the database. I want to export this date to a .txt file. This is enforced by my business requirements so exporting it to Excel or PDF is not an option!! I also need to be able to prompt the user for location of where they want to save this file and what they want to name it. Does telerik have any controls that will help me accomplish these tasks? I have looked into the ClientExportManager and the export functionalities of the RadGrid and TreeList, but nothing exports data to text file that I can see.

thanks

RadGrid Inline Add - Default Focus

My customer would like the default focus set so when they click the add new record button the focus is set to the first textbox on the input line so they can begin typing without having to click the field first. Is this possible? I don't see any settings that would suggest so. Perhaps a sneaky code behind trick? Any tips greatly appreciated.
