Radgrid Exporting Excel - Problem with Guids

Hi everyone,

I'm using a Radgrid to show some information... One of the features i've decided to set is the Export to Excel.

Everything works fine, except for some fields that are Guids.... Those values for the guids don't are exported to the file.

Any help would be very appreciated.

Grid items are being lost between posts

I have a radGrid and am trying to get the ItemCommand buttons working. When the item command button is clicked the ItemCommand event filres and I can see here that the grid has 4 items (rgdGrid.Items.Count = 4). But when the page pre render event fires the items have been lost (rgdGrid.Items.Count = 0).

I bind data programatically then the grid is first shown and do not need to do it again. Viewstate is enabled for this grid control.

Any ideas?

RadGrid & Insert form in codebehind

Hi all, i have a problem with RadGrid.

When i enter into a page where there is a RadGrid, i want that RadGrid Insert Form is opened.

I have looked for on the forum but i didint find any solution for my problem.

I tryed what you suggested in the following forum

http://www.telerik.com/community/forums/aspnet/grid/i-want-call-radgrid1-insertcommand-from-a-button-out-of-rad-grid.aspx#484224

but my case is a bit different.

I have tryed to call

radgrid1.Items[0].FireCommandEvent("InitInsert", string.Empty)

in Page_Load and this works if i have at least 1 item. If my RadGrid is empty, it fires and exception because the radgrid1.Items[0] doesn't exist. Can you give me a little advice?

Many thank
Alessandro

Error when call RadAlert

I'm getting this error constantly:

http://i.imgur.com/CYPdu.jpg

This happens when I click in a RadButton that fires a RadAlert using this:

DirectCast(Me.Page.FindControl("WindowManager"), RadWindowManager).RadAlert("Endereço foi salvo com sucesso.", 330, 100, "Sucesso", "alertCallBackFn")

My WindowManager is:

<telerik:RadWindowManager ID="WindowManager" runat="server" EnableShadow="true" EnableViewState="false" ReloadOnShow="true">

<ConfirmTemplate>

<div class="rwDialogPopup radconfirm">

<div class="rwDialogText">

{1}

</div>

<div>

<a onclick="$find('{0}').close(true);" class="rwPopupButton" href="javascript:void(0);"><span class="rwOuterSpan"><span class="rwInnerSpan">Sim</span></span></a> <a onclick="$find('{0}').close(false);" class="rwPopupButton" href="javascript:void(0);"><span class="rwOuterSpan"><span class="rwInnerSpan">Não</span></span></a>

</div>

</ConfirmTemplate>

</telerik:RadWindowManager>

And my callback function It's:

<telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">

<script language="javascript" type="text/javascript">

function alertCallBackFn(arg) {

CloseRadWindow();

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow;

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow;

return oWindow;

}

function CloseRadWindow() {

var oWindow = GetRadWindow();

oWindow.argument = null;

oWindow.close();

return false;

}

</script>

</telerik:RadCodeBlock>

All this code is on a page that is opened through RadWindow, and the error happens before the RadAlert it is shown.

Alpha blend in grid selection not work in FireFox new version 13.0.1

Several days ago my FireFox browser was automatically updated to 13.0.1, now when I run the demo page of RAD Grid in this address, the selection function alpha effect is no more available but a blue block.

Address of demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/columntypes/defaultcs.aspx

Screen snapshot:
See attached JPG.

Related property: ClientSettings.EnableDragToSelectRows

Is this a conflict between RAD ajax control and FireFox 13.x new release?

DataItem lost after postback caused by UserControl

Hello,

I have a RadGrid with EditFormType="WebUserControl". The UserControl has a view model (custom class) and controls on the UserControl binds to the view model. And there are radio buttons on the UserControl that causes postback.

I'm setting the UserControl's property in RadGrid's ItemCreated property. Everything works fine until a postback is caused by the UserControl - RadGrid's ItemCreated event fires, but the DataItem property (e.Item.DataItem) of GridItemEventArgs is null after postback. So I can't set the UserControl's view model property.

Is there a way to retain the DataItem even after a postback caused within the EditForm/UserControl?

Thanks in advance!
Makoto

[Solved] Node Alignment Issue

I just upgraded to the latest release of the AJAX tools and have run into an issue with the Org Chart control, the nodes are not being displayed correctly. Please see attached images for the issues that I am having. Also here is the code that creates the Org Charts for the respective images.

OrgChart align issue.png Code:

private void LoadEmployees()

{

Directory_BO.Collections.Employees tmpEmployees = new Directory_BLL.OfficeManager().GetOfficeEmployees(OfficeToDisplay.ID);

if (tmpEmployees.Count > 0)

{

tblNoEmployees.Visible = false;

}

else

{

radTabEmployees.Enabled = false;

return;

}

//Set the text of the tab

radTabEmployees.Text = "Employees (" + tmpEmployees.Count + ")";

//Get the Distinct Ability Types

var distinctDivisions = tmpEmployees.Cast<Directory_BO.Employee>().GroupBy(c => c.DivisionName).Select(grp => grp.First()).OrderBy(o => o.ContactDivision.Code);

//Create the Tabs and MultiPage pageviews

foreach (Directory_BO.Employee div in distinctDivisions)

{

var tmpDivEmployees = tmpEmployees.Cast<Directory_BO.Employee>().Where(c => c.ContactDivision.ID == div.ContactDivision.ID);

//Add Multipage for the Division

Telerik.Web.UI.RadPageView tmpPageView = new Telerik.Web.UI.RadPageView();

tmpPageView.ID = "radPV" + div.ContactDivision.Code;

radMPEmployees.PageViews.Add(tmpPageView);

//Add Tab for the Divison

Telerik.Web.UI.RadTab tmpTab = new Telerik.Web.UI.RadTab((div.ContactDivision.Code != string.Empty ? div.ContactDivision.Name : "Not Listed") + " (" + tmpDivEmployees.Count() + ")", div.ContactDivision.ID.ToString());

tmpTab.PageViewID = tmpPageView.ID;

radTSEmployees.Tabs.Add(tmpTab);

//Create and load the RadOrgChart

Telerik.Web.UI.RadOrgChart tmpOrgChart = new Telerik.Web.UI.RadOrgChart();

tmpOrgChart.EnableEmbeddedBaseStylesheet = false;

tmpOrgChart.EnableEmbeddedSkins = false;

tmpOrgChart.Skin = "IntertekEmployee";

tmpOrgChart.GroupColumnCount = 3;

tmpOrgChart.DisableDefaultImage = true;

tmpOrgChart.ItemTemplate = new EmployeeItemTemplate();

//Table to hold the data for the items

DataTable itemsTable = new DataTable();

itemsTable.Columns.Add("NodeID");

itemsTable.Columns.Add("FullNameLink");

itemsTable.Columns.Add("Title");

foreach (Directory_BO.Employee tmpC in tmpDivEmployees)

//Add a top border

Literal tmpLiteral = new Literal();

//Add the RadOrgChart to the Mulitpage

radMPEmployees.FindControl(tmpPageView.ID).Controls.Add(tmpLiteral);
