Random Bar Chart

Greetings.

We are trying to display a simple bar chart. This bar chart has to display following values:

X-Axis    Y-Axis
A              2
B              2
C              2
D              2
E              2

But when we try to run the page, each time we get different chart. Sometime the bars are overlapping. Please help.

We are using AJAX controls Q3 2010.

Changing targetfolder handling

ASP.NET framework 4.0
Windows 7
RadControls for ASP.NET AJAX Q2 2011
preferred programming C#

I have a question about how to change the RadAsyncuploading handling of saving to the targetfolder.

The situation as i want it goes as follows: The user is able to select his files/images and they are saved in the temporaryfolder. This way i can view the images with the webviewer im using. Also the utility RadASyncUploader helps with deleting files that are not being used or not being deleted and so on..
But i do not want to save the files to another targetfolder but i want to save them in a database. How can i make this happen?

Im rather new to web programming and i really could use the help. Saving to a database i can do ofcourse but where do i change the handling of saving to the targetfolder

THanks in advance,

Koen Staal

RadGrid Rebind can't access C# globals in callback

I have a RadGrid that loads from a DataTable pulled from my database. The user can click a "Refresh" button on the page that will update the database behind the scenes, then update various labels on the page as well as the RadGrid from the new database entries, all through RadAjax. The labels correctly update, but the problem comes when I call RadGrid1.Rebind();

The "Refresh" click code sets two global variables in the codebehind and then uses those values in updating the page. Then Rebind() gets called at the end of the function, and in the process, processes each row of the grid. One column in each row calls a function that uses one of the global variabes set earlier to genereate an image URL. However, even though the same global variable was accessible in the Callback code, in the Rebind code it is suddenly NULL. I get a Javascript error and the RadGrid doesn't get updated.

Summary: How do I set variables in my RadAjax callback function that will be accessable by the functions Rebind calls when repopulating my RadGrid?

Thanks in advance for your help.

[Solved] Radgrid sorting does not work while paginating

Hi All,

Sorting does not work in my radgrid when I paginate it. If I keep AllowPaging=false, then columns are properly sorted. I tried to sort it using sort expression as well as code-behind but same issue. I also referred to official example given online, but it did not help.

Please guide if I am missing something. Thanks in advance!!!

rcbclient.DataSource = getClients()

rcbclient.DataBind()

from Default.vb

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim userControl As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)

'Prepare new row to add it in the DataSource

Dim newRow As DataRow = Me.Staging.NewRow

'Insert new values

Latest RadEditor in AJAX has postback in Firefox 6

Hi,
I've just downloaded the latest version (DEMO) of Telerik ASP.NET AJAX controls.
I wanted to check if there is the option to use UpdatePanel or RadAjaxPanel to submit the content from the editor in AJAX postback.

Generally it is possible. But it doesn't work in my Firefox. I have Firefox 6.0.2 and each button in my example makes classic postback.
I did it on the basis of that page.

Here you have my code. All the 4 clicks make classic postback in FF. I need to use AJAX and it should work in the latest FF, IE (7,8,9), the latest Chrome, and the latest Safari.

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<asp:Panel ID="pnlRadEditor" runat="server">

<div>

Standard Button: <asp:Button ID="btnSave" UseSubmitBehavior="false" runat="server"

OnClick="btnSave_Click" Text="Save" /></div>

<div style="margin-top: 10px;">

Image Button: <asp:ImageButton ID="ImageButton1" runat="server" OnClientClick="javascript:__doPostBack(this.id,'');return false;"

OnClick="btnSave_Click" ImageUrl="http://www.telerik.com/DEMOS/ASPNET/RadControls/Editor/Skins/Default/buttons/save.gif" /></div>

<div style="margin-top: 10px;">

<telerik:RadEditor ID="RadEditor1" runat="server" EnableViewState="false">

</telerik:RadEditor>

</div>

</asp:Panel>

</telerik:RadAjaxPanel>

<div>

Standard Button: <asp:Button UseSubmitBehavior="false" ID="Button1" runat="server"

OnClick="btnSave_Click" Text="Save" /></div>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<Triggers>

<asp:AsyncPostBackTrigger ControlID="Button1" />

</Triggers>

<ContentTemplate>

<div style="margin-top: 10px;">

Image Button: <asp:ImageButton ID="ImageButton2" runat="server" OnClientClick="javascript:__doPostBack(this.id,'');return false;"

OnClick="btnSave_Click" ImageUrl="http://www.telerik.com/DEMOS/ASPNET/RadControls/Editor/Skins/Default/buttons/save.gif" /></div>

<div style="margin-top: 10px;">

<telerik:RadEditor ID="RadEditor2" runat="server" EnableViewState="false">

</telerik:RadEditor>

</div>

</ContentTemplate>

</asp:UpdatePanel>

</form>

Gridview not refreshing even when ajaxrequest is executed

Hi,

I have a asp gridview on the parent page and there is a button outside of the grid. On button click, radwindow popup appears. When the user closes the popup, it invokes the RadajaxManager's ajaxrequest on the parent page. The code steps into the _ajaxrequest and does gridview.databind. I can see that the number of rows are correct in the grid but when the process is complete, the grid does not refresh. I tried by replacing the asp gridview with Radgrid but still had no success.
I am pasting my code here. Please let me know if I need to give more information.

Any help is greatly appreciated..

btnDelegate lauches the radwindow.

function

openRadWindow(args) {

var EmpID = $find("<%=cboEmployee.ClientID %>")._value;

window.radopen("AdminDelegationPopup.aspx?EmpID=" + EmpID + "&Type=" + args, "RadWindow1"); }

function refreshGrid(arg) {

if (arg == 'Delegation') {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Delegation"); // Invoking ajaxRequest }

}

AjaxRequest..I am able to step into the following code succesfully.

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs)

If e.Argument = "Delegation" Then

Dim oDelegation As New Delegation

Dim dsDelegatedRights As

DataSetdsDelegatedRights = oDelegation.GetDelegatedRights(cboEmployee.SelectedValue)grdDelegatedRights.DataSource = dsDelegatedRights

grdDelegatedRights.DataBind()

End If

End Sub

this is on the radwindow.

function

CloseAndRebindGrid(args) {

GetRadWindow().Close();

GetRadWindow().BrowserWindow.refreshGrid(args);

}

Changing the RadDatePicker Calendar Popup Icon

I like to use the Web20 skin for the popup calendar itself in a RadDatePicker, but I prefer the calendar popup icons from the other skins. I know I can change the icon with the DatePopupButton-ImageUrl property, but I don't know how to reference the icons that are now embedded. Of course with the old ASP.NET controls, I had a folder and a file to point at. How do I access that resource now?

Thanks!

GridView - ClientLoad - CSS Styles

Hi,

I am having a problem with the RadGrid and data binding from a web service.

The data is loaded in correctly but the styles are not set correctly for any items that appear after the items in the initial load.

For example, the Grid has 10 items when the page loads, all 10 items are displayed correctly, with Item height, CSS classes and Align working as they should.

However after the WebService update, all new items (any items above the first 10) will not be displayed correctly.

I've put together a simple project to demonstrate this problem, it seems to apply to all browsers. I'll see if I can upload it here somehow.

Thanks

Mike

nb, I cant see to be able to upload the project file here, any suggestions on how I can get it to you?
