Hi there.

I have a grid where I am binding a data table. The first column is a check box. The problem is that it is read only on the grid.

What I want is a column with a check box that can be checked and unchecked. Also i want the same with its header. When the header check box is ticked, all the other check boxes should be ticked as well.

This is what i have right now

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AutoGenerateColumns="true">

<MasterTableView>

<CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

<RowIndicatorColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<Columns>

</Columns>

</MasterTableView>

</telerik:RadGrid>

System.Data.DataTable dt = new System.Data.DataTable();

System.Data.DataColumn column0 = new System.Data.DataColumn("IsEnabled", typeof(bool));

System.Data.DataColumn column1 = new System.Data.DataColumn("Rule", typeof(string));

System.Data.DataColumn column2 = new System.Data.DataColumn("Status", typeof(string));

System.Data.DataColumn column3 = new System.Data.DataColumn("Priority", typeof(string));

System.Data.DataColumn column4 = new System.Data.DataColumn("UpImg", typeof(string));

System.Data.DataColumn column5 = new System.Data.DataColumn("DownImg", typeof(string));

dt.Columns.Add(column0);

dt.Columns.Add(column1);

dt.Columns.Add(column2);

dt.Columns.Add(column3);

dt.Columns.Add(column4);

dt.Columns.Add(column5);

System.Data.DataRow row = dt.NewRow();

row[column0] = true;

row[column1] = "test";

row[column2] = "test";

row[column3] = "0";

row[column4] = "test";

row[column5] = "test";

dt.Rows.Add(row);

RadGrid1.DataSource = dt;

RadGrid1.DataBind();

Thanks in advance

TelerikModalOverlay

I have successfully managed to use the TelerikModalOverlay class to put an image behind a modal pop-up window, but I have a small issue in that the background image is not centered in the background and starts from the top-left of the browser. Below is the CSS I am using currently:

.TelerikModalOverlay
{
    background-position: center top !important;
    background: url(images/backgroundmain.jpg) !important;
    background-repeat: no-repeat;
    filter: alpha(opacity=99) !important;/*for IE 5.5+*/
    opacity: .99 !important;/*for FF 2x, Opera 9x*/
    -moz-opacity: .99 !important;/*for FF 1x*/
    }

Is there any way to force the background image to be centered?

Thanks

Can I hide the Delete button...

... on a per appointment basis.

That is to say, when I'm handling the AppointmentDataBound event, I do some tests to check whether, for that appointment, the user has sufficient rights to edit or delete an appointment and I set up the context menu accordingly. I'd like, when the user has insufficient rights to delete the appointment, to hide the delete button too.

So far all I've found are suggestions on how to hide it for all appointments.

Any suggestions?

MinFileSize Property

Hi,

I would appreciate if you can tell me if there is a property for minimum file size similar to MaxFileSize. My requirement is to prevent the user from uploading an empty (0KB) file. Most of our users use Internet Explorer and whenever they try to attach a file (empty/0KB), progress bar doesn't move at all and gets stuck in a limbo. It seems to be working fine in Firefox though.

In order to go around this problem, we have decided not to allow the user to upload empty files (0KB). Is there such a property for RadAsyncUpload that prevents the user from doing so?

My html looks something like this:

<telerik:RadAsyncUpload ID="uplCVAsync" runat="server" MaxFileInputsCount="1" MultipleFileSelection="Disabled"

EnableInlineProgress="true"

AllowedFileExtensions='<%#AllowedExtensions%>' MaxFileSize="<%#MaxFileSize%>" OnClientProgressUpdating="checkUploadedFilesSize"

OnClientFileUploading="fileUploadStart" OnClientFileUploaded="fileUploadEnd"

OnClientFileUploadFailed="fileUploadEnd" OnClientValidationFailed="fileUploadValidationFailed">                                            </

telerik:RadAsyncUpload>

If this property is not available, please advice other alternatives?

Irfan,

AsyncUpload

Forcing refresh by Javascript

Hy
I do have the following scenario: I am having a Radgrid inside a visual Webpart which is using AJAX. The Radgrid with the Loadingpanel exists within the UserAdministrationUserControl, the RadAjaxmanager is added to the UserAdministrationWebpart.cs by following code:

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

ajaxmgr = new RadAjaxManager();

ajaxmgr.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(AjaxManager_AjaxRequest);

Page.Items.Add(typeof(RadAjaxManager), ajaxmgr);

Page.Form.Controls.AddAt(0, ajaxmgr);

}

protected override void CreateChildControls()

{

Control control = Page.LoadControl(_ascxPath);

Controls.Add(control);

RadGrid panel = control.FindControl("RadGrid1") as RadGrid;

RadAjaxLoadingPanel loadingPanel = control.FindControl("RadAjaxLoadingPanel1") as RadAjaxLoadingPanel;

ajaxmgr.AjaxSettings.AddAjaxSetting(panel, panel, loadingPanel);

}

So far it works quite well. However I have the scenario, the Edit-Button of the Radgrid opens a ModalDialogPopup for editing the selected User. When editing is finished and the ModalDialog is closed, the Radgrid should be reloaded/refreshed. This is possible by a javascript function, which is called after closing the modaldialog by a callback. And here is my problem.

The Callback-function should do just the following:

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

But of course that isn´t possible as the RadAjaxmanager doesn´t exist in the UserControl, where the Javascript and the other controls are.

I´ve tried giving the RadAjaxmanager an Id and finding it by:

$find('<%# this.Page.Forms.FindControl("MyRadAjaxManager").ClientID %>').ajaxRequest("Rebind");

But that doesn´t work, the Control cannot be found (in the console it returns the function as "$find('').ajaxRequest("Rebind") ).

While Debugging, I´ve found out, that the AjaxManager always gets the same ClientID, so the following is starting a refresh (i didn´t set the controls ID in that case):

$find("ctl00_ctl44").ajaxRequest("Rebind");

However, I do not want to hardcode the Controls ClientID. Besides, altough it is updating the Radgrid in that case, the LoadingPanel does not show up by using that Javascript (it works without a harm in all other cases eg. paging). And therefore it is not very userfriendly.

Any Help and suggestions will be very appreciated

Regards

Ajax
