Handling client event OnRowResized in server-side

Hello,

How do you pass back to the server the event args in a OnRowResized event on the client-side?

I got it to work in a OnRowClick event by having this statement in my code behind:


RadGrid1.ClientSettings.EnablePostBackOnRowClick = True 
RadGrid1.ClientSettings.ClientEvents.OnRowClick = "On_Row_Click" 


AddHandler RadGrid1.ItemCommand, AddressOf RadGrid1_ItemCommand

And in my .ASCX I have this:


function On_Row_Click(sender, eventArgs) { 
  __doPostBack(sender.ClientID, "RowClicked:" + eventArgs.get_itemIndexHierarchical()); 
}

When a row is clicked, it runs the __doPostBack command above and I catch the postback on the server side in my code behind:


 
Private Sub RadGrid1_ItemCommand(sender As Object, e As GridCommandEventArgs) 
   'Client-side event is caught here !!!
End Sub

How do I accomplish the same thing for a client-side OnRowResized event?

If anyone can give a quick response (or a working example), it would be highly appeciated.

Thanks.

Hello,

I'm using your RadAsyncUpload and it works perfectly for uploading images however, I need to create a little thumbnail for each FileImput when FileUploaded event occurs (before saving in destination folder). The problem is that I need to associate the filename uploaded in temporary folder, to image element but I don't understand how can I do. I'm using OnClientFileUploaded event but I don't understand how can I take the filename of image uploaded. I hope that you can help me.

RadDockLayout not storing layout state

Hi - I have a raddock that is not retaining its state after a postback.
Scenario: I expand the dock, do some operation that triggers a postback, and when the page loads again, the dock is collapsed.
Expected: I want the dock to retain state, and load expanded.

I was using rad controls version 2009.1.402.20 and this was behaving fine. I'm currently updating to version 2011.3.1115.35 and I'm facing this problem.

Here's a sample of the code that I'm using -

<telerik:RadDockLayout runat="server" ID="[DUMMYID-1]">
    <telerik:RadDockZone runat="server" ID="[DUMMYID-2]" Orientation="vertical" Skin="Vista" Width="99.7%">
        <telerik:RadDock runat="server" ID="[DUMMYID-3]" Title="More"
            Style="min-height: 0px; margin: 0px auto; visibility: hidden;" Collapsed="true"
            DefaultCommands="ExpandCollapse" Skin="Vista" EnableDrag="false"
            DockHandle="None" Width="99.5%" BorderStyle="None">
            <ContentTemplate>
             ...... [some code here]
            </ContentTemplate>
    </telerik:RadDock>
</telerik:RadDockZone>

I tried adding the following to the raddocklayout attributes but this doesn't help.

EnableViewState="true" StoreLayoutInViewState="true"

Appreciate any help. Thanks.

ps: Also if you could point to me some documentation that would help me migrate from older version to newer version of rad controls for asp.net ajax.

Format data value in GridBoundColumn

Hi!
I have a general problem when binding my data to a grid and getting all functionality to work smoothly without to much hands on.

What I do is that I have data that I want to display and use built in functionality like sorting, filtering and grouping.
My data is not always in a presentable shape so I need to format the data output before presenting it in a column. This is not a problem since I can use templates or FormatDataValue in a derived GridBoundColumn. The problem is that the sorting, filtering and grouping will not work without lot's of specific coding.

I would like to find out a way to in one place (like a derived GridBoundColumn) take care of the conversion/presentation of the data value in a way that it will more or less automatically be mirrored in filtering, sorting and grouping.

As an example I sometimes store time as an integer for minutes. When showing the data value I convert it to "mm:ss". The problem is now that the GroupHeaderItem is showing the integer and the filter box is working with the integer as well.

Any suggestions on how to solve this in a generic way?

Thanks
Mats

ContextMenu with mutually exclusive behaviour (group/ungroup)

Hi,

In a ContextMenu how do I make this:

- Show only "Group" option when the column is ungrouped (not for all the column, just for the column that is ungrouped).

- Show only "Ungroup" option when the column is grouped.

I tried this:

But this hides both (group/ungroup options)

void HeaderContextMenu_GroupsChanging(object sender, GridGroupsChangingEventArgs e)

{

if (e.Action == GridGroupsChangingAction.Group)

this.MasterTableView.GetColumn(e.Expression.GroupByFields[0].FieldName).Groupable = ...;

else if (e.Action == GridGroupsChangingAction.Ungroup)

this.MasterTableView.GetColumnSafe(e.Expression.GroupByFields[0].FieldName).Groupable = ...;

}

Any help?

            ddlDriverA.commitChanges();

Panel bar size in RadPane in RadSplitter

Hi,

I have a RadPanelBar in a RadPane which is part of a Rad Splitter. I have one vertical splitter, thus one left pane and one right pane. The panel bar is in the left pane and should resize to maintain the width of the left pane as the left pane resizes.

In my attempt to accomplish this, I have caught the OnClientBeforeResize event on the RadPane. I then set the width of the PanelBar accordingly. I have used the http://www.telerik.com/help/aspnet-ajax/panelbar-resize-to-the-width-of-the-widest-radpanelitem.html for guidance. I try to retrieve the current width of the bar then add the value from args.get_delta() on the BeforeResize event but I am not getting any joy here since panelBar.width() returns null and panelbar.width(500) (for example) simply doesn't resize the bar.

This is in IE8 and I notice that the documentation guidance linked to above specifically tests for IE6 and IE7.

Please help!

Thanks

function RadPaneMainNavigation_OnClientBeforeResize(sender, Args) {

alert(Args.get_delta());

var panel = $telerik.$("<%= PanelBarNavigation.ClientID %>");

alert(panel.width());

panel.width(500);

}
