CustomValidator client function fires multiple times after postback.

After the postback of the RadGrid in one update panel, the custom validator in another panel fires numerous times. The more postbacks you do on the RadGrid, the more times the validator will fire.

Here is the sample code. Watch "Count: 0" before a postback and after selecting a row or two in the RadGrid.

Before postback, the validator runs once every time you change the textbox or press the button. After selecting a couple of grid rows, it will fire multiple times....

You can execute the validator by changing the text in the text box to anything other than "hello"...

Move the validator out of the ajaxified table and it works as expected...

How can I have the custom validator inside the ajaxified table act properly after postback?

How to open usercontrol as editform from commanditemtemplate?

Hi all,

I have a commanditemtemplate with a button that I would like to use to edit one row from the radgrid using a popup usercontrol.

The situation:
I cannot edit the row with the GridEditCommandColumn because there is only one row in the entire grid that is allowed to be edited, and I don't want to work with hiding buttons because I think it's an ugly solution. Therefore I would like to edit the row by pressing a button at the commanditemtemplate.

Unfortunately, the popup doesn't show. I probably forgot some setting somewhere, could someone please help me?

aspx code snippet

<MasterTableView DataKeyNames="keyName" AllowMultiColumnSorting="True" EditMode="PopUp"

CommandItemDisplay="Top">

<EditFormSettings EditFormType="WebUserControl" />

<CommandItemSettings ShowAddNewRecordButton="false" AddNewRecordText=""

ShowRefreshButton="false" RefreshText="" />

<CommandItemTemplate>

<telerik:RadButton ID="RadButtonDone" runat="server" Text="Done"

CommandArgument="Done" CommandName="Edit"

ToolTip="Mark the item as done">

<Icon PrimaryIconUrl="Images/done.gif" PrimaryIconLeft="8"

PrimaryIconTop="5" />

</telerik:RadButton>

</CommandItemTemplate>

code behind c#:

protected void RadGridMyGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.EditCommandName)

{

// Change status to 'Done'

if (e.CommandArgument == "Done")

{

SessionState.Current.intKey =

GetKeyValueFromRowThatIsAllowedToBeEdited(ValueFromSessionState);

e.Item.OwnerTableView.IsItemInserted = false;

e.Item.OwnerTableView.EditFormSettings.PopUpSettings.Width = 700;

e.Item.OwnerTableView.EditFormSettings.PopUpSettings.Modal = true;

e.Item.OwnerTableView.EditFormSettings.UserControlName =

"ChangeStatusToDone.ascx";

}

Thank you!

$.ajax not working on Scheduler Client Event - IPad

Hi

I have a Scheduler Control where i have defined a function on onclientappointmentmoveend="OnClientAppointmentMoveEnd" and within my function i have something like this

function OnClientAppointmentMoveEnd(sender, eventArgs) {
MyFunction(eventArgs, "onMove");
}

function MyFunction(eventArgs, action) {
    $.ajax(
     {
          url: url,
          data: parameter,
          contentType: "application/json; charset=utf-8",
          success:
          function (data) {
               CallbackFunction(data, eventArgs,action);
           },
      type:'POST',
      dataType: 'json',
      async: false
});

}

function CallbackFunction(data, eventArgs,action) {
..........
.......
.........

}

Now, my callback function works fine on any windows browser but this callback function is not executed on IPad. Is there something that is missing to make it execute on IPad?

Org Chart with bread crumbs

Hi,
While I really like this feature, there appears to be a potential issue with it.
If I have multiple roots, it seems the breadcrumb feature doesn't work. It seems to go to the first root item. Which is fine, until you drill into it. Once drilled in, there is no way for the user to get back to the level with the multiple roots. Only to the root item that was drilled on.
Any ideas?
Thanks ... Ed

Radmenu doesn't close when another radmenu on the page is clicked

I've got 2 radmenus on the same page that have clicktoopen set to true.

If I click on a menu it opens, then if I click away it closes. Unless I click on the second menu, then the first menu remains open and the second menu opens up as well.

I would like to have the first menu close when the second menu is clicked.
I tried adding a onblur client event to the menus where I close the menu if focus is taken away, but that caused 2 issues.

1) The clicked property remains set to 'true' so when I hove the mouse the menu opens up again without having to click.
2) I have a checkbox inside of the menu template, when I click the checkbox, the menu technically loses focus and tries to close then immediately reopens.

Concerning point 1.
If I set clicked to false in the same event, then the menu can't be closed by clicking on it a second time, it starts to close then immediately reopens again.

Thanks,
Javier

        RadUpload ruThumbnail = (RadUpload)e.Item.FindControl("ruThumbnail");



        if (ruThumbnail.UploadedFiles.Count > 0)

        {

            // execute SaveAs

TimePicker handle only minutes

Hi.

I would like to know if its possible to set the TimePicker to handle only minutes?
So instead of having an input of "01:30" (HH:mm) it should be 90 only.

Also that the PopUp to pick values, displays as follows

instead of --> it should be
00:55 --> 55
01:00 --> 60
01:05 --> 65
and so on...

Hope you can help me.

RadGrid to generate Report

Hi,

I'm trying to figure out the best way to achieve the following scenario:
1. Have a RadGrid display a table of information i.e.

Customer	# of Orders	# of Products Ordered	Total Revenue
John Doe	10	23	$2300.00

2. When client selects a row, to generate a report ( such as a breakdown of orders) that provides more detailed information on a value (i.e. Customer's name) in selected row.

Thanks,
Yankev
