DateTimePicker vs. ObjectDataSource and Validation

Greetings,

first of all I have to say that I like DateTimePicker and other calendar controls. Thus my frustration is much more deeper. I have a validator which is able to validate a date against desired date format. But with RadDateTimePicker it's useless, because date string, which is supplied to the validator is in strange only-dash-separated format (e.g. 2010-05-12-01-31-00 - I understood it is ValidationDate property). Now there is a bad security problem, when one turns his javascript off, and enters a date the format supplied to the validator will be different. When my validator expects format like 'yyyy/MM/dd' it is able to validate it when someone cheats. But when normal user enters a date and it is deformed by the DateTimePicker control, it cannot be validated against desired format 'yyyy/MM/dd'. Now it is NOT STANDARD behaviour. I expect that the control won't modify standard behaviour. It's Microsoft's job to disobey standards, please, don't do so... The controls should only sweeten one's work, but should not deform the values input by user.

I have read lots of posts on this problem, ClientEvents-OnError as the best proposed solution is not still validation and works only on client-side. Another proposion to use SelectedDate in server validation method also does not work as it is null on all invalid inputs and validator returns true. And RangeValidator, it's the same thing. Any other working solution, that everybody is still awaiting?

All solutions are welcome.

RadGrid1_ItemDataBound fires only for rows in first page

Hello, I have paging enabled for the radgrid control. I bind the radgrid to a datatable. In the RadGrid1_ItemDataBound , I would like to go over every row bound to the grid and based on the value of a cell, I want to change the background color of the corresponding row. This works fine when paging is not enabled(that is all rows bound to the radgrid is on one page). But when I have multiple pages, I see that RadGrid1_ItemDataBound event gets fired only for rows in the first page.
Thanks for your help!

Column Headers not being exported to Excel when More then 10 Rows are exported

2 problems here;
1. Header row (column titles) are not exported to Excel when I have more than 10 items in a export. I thought it might be related to the page size so I changed my page size to encompass 12 rows and still no header row.
2. I am unable to get the entire dataset to export to excel. I can only get the 1st page. See code snipit

ActiveBatchesRadGrid_ItemCommand calls the method ConfigureExport in the base class so all exports function the same

private void ActiveBatchesRadGrid_ItemCommand(object source, GridCommandEventArgs e)

{

switch (e.CommandName)

{

case RadGrid.InitInsertCommandName:

_gridTableView = e.Item.OwnerTableView;

break;

case RadGrid.ExportToExcelCommandName:

ExpandAllDetailTableRecords(source, ExpandedStates, false);

ConfigureExport(source, e);

break;

}

protected static void ConfigureExport(object source, GridCommandEventArgs e)

{

e.Item.OwnerTableView.ExpandCollapseColumn.Visible = false;

e.Item.OwnerTableView.GetColumn("PolicyEditRecord").Visible = false;

e.Item.OwnerTableView.GetColumn("DeleteTransaction").Visible = false;

e.Item.OwnerTableView.GetColumn("ManualAdjustmentBatchID").Visible = false;

e.Item.OwnerTableView.GetColumn("ManualAdjustmentID").Visible = false;

((RadGrid)source).ExportSettings.ExportOnlyData = true;

//((RadGrid)source).PageSize = ((RadGrid)source).MasterTableView.VirtualItemCount;

((RadGrid)source).ExportSettings.IgnorePaging = true;

((RadGrid)source).ExportSettings.OpenInNewWindow = false;

((RadGrid)source).MasterTableView.HierarchyDefaultExpanded = false;

((RadGrid)source).MasterTableView.ExportToExcel();

}

VirtualItemCount is commented out because it throws an "System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values." error. I have not tried it yet but I think it may be due to the export being conducted on the DetailGrid and not the MasterGrid. Any comments on that would be appreciated too.

EDIT:
After further investigation the lack of the export of the header row does not appear to be a row count issue. It appears that only the first DetailGrid of the first row of the MasterDetailGrid exports the column headers. I have tried this on all of my implementations and the behavior is consistent across them

Modifying Grid Filter Menu Causes Loop

I am trying to modify the filter menus in a grid. I have done this before (successfully), so I copied the event code from the other web page that was working fine, pasted it into a second .aspx, and everytime it executes it goes into a CPU loop -- which I cannot locate the source of using normal debugging techniques.

I have attached a screen capture of the grid at run-time so you can visualize it.

The source code for the actual grid is immediately below, and the related event code which is causing the problem is included below that. If I comment out the event code, the page runs fine. If I let the While..Loop execute, a cpu-loop will result without any debug stops being executed.

Any help would be most appreciated! It will probably turn out to be something stupid I am doing, but for the life of me, I cannot find it.

Thanks for any assistance in advance!

rad controls compatible with asp.net wizard control

Are telerik's asp.net ajax controls compatible with Microsoft's asp.net wizard control? I need to be able to utilize the wizard control to handle a particular data entry issue, but don't know if Telerik's controls will work without issues when used in that environment.

Are there any caveats, concerns, issues, workarounds, etc. that I need to be aware of?

Thanks in advance!

Lynn

Postscript: I assume since this has sat here for 2+ days without any response that the answer is "no"?

Column Header Alignment

I'm having the same issues outlined in many other threads. That is that my column headers do not align with my column's content. I'm using the latest telerik build and I've had no issues with IE or Firefox however Chrome and Safari (windows) don't work. I've tried the following steps which I've found in this forum:

Made sure non of my columns are using the ItemStyle-Width (only HeaderStyle-Width).
Set my MasterTableView 'TableLayout' to Fixed.
Handled the OnGridCreated client event to force the grid to repaint.

None of these options fixed the issue. One setting that seemed to get me closer was removing HeaderStyle-Wrap=False and ItemStyle-Wrap=False. Again setting each of these to false got me much closer however they were still way off. Any help with this would be greatly appreciated as time is of the essence. Thank you.

ItemTemplate and ClickToOpen

Hello!

We want to use ClickToOpen on the root level of a menu.
At the same time we are using an ItemTemplate for the root level.

This combination doesn't work at all. Nothing happens when clicking the menu-item.
When looking at the source code it is obvious that it doesn't work since no a-tag is generated if it is templated.

Will this be fixed? And is there a workaround to get this to work until it is fixed?

Regards
Rikard
