RadDatePicker - preserve invalid data entry on postback?

I have a "bug report" where they are complaining that when you enter invalid/non-parsable data (such as "oapsd") via the keyboard into a RadDatePicker or a RadTimePicker, the invalid input does not persist on postback. They wanted the invalid input to be preserved for the user to correct upon explicit prodding, rather than clearing it for them and asking them to do it over again.

Is this something we can do easily?

'Sys' Undefined Java Script Error - Sys.Application.add_init(function()

The web application runs fine on my local DEV machine. When published to the web server, all pages that have RadControls generate a Java Script Error. "'Sys' undefined" when the page loads.

Checking the forums, there are lots of references to configuring the application to run AJAX.

I have tried adding a <location> section to add user authorization - no change.

When I run the "configure application" wizard from the Telerik menu in VS2010, it changes my web.config file and adds additional information in the <modules> tag: <modules runAllManagedModulesForAllRequests="true">
With that added, I get an internal server error on the web server when I try to load the page,

Any ideas?

$find("radTxtB"); at window.onload doesn't work

Hi,

If I run the jscript function [Disable] on a button click, it works perfect, but, when this function is called by the window.onload, I get a error. The error ocorre because $find doesn't return a valid object, instead, it return a null. Why this happen? There is a way to work around it?

window.onload = function()

{

Disable();

}

function Disable()

{

var txt = $find("RadTextBox1");

txt.disable();

}

Details displaying twice

Hi,
I have a hierarchical grid that I am binding to a dataset. One table is summary data and the second table is the detail data. I have definied a relation using a field called ExpenditureType. I am building all of my columns dynamically. All works well, but my details table displays twice when I expand. The code is pretty simple, so I can't figure out what is causing it. I have attached a screenshot as well. Do you see what I am doing wrong?

Thanks! Tami

private void BindGrid()

{

RadGrid1.DataSource = _dsBudgetVerification.Tables["BVSummary"];

RadGrid1.Width = Unit.Percentage(98);

RadGrid1.AutoGenerateColumns = false;

RadGrid1.GridLines = GridLines.Both; //TODO: This doesn't seem to work

RadGrid1.MasterTableView.DataKeyNames = new string[] { "ExpenditureType" };

RadGrid1.MasterTableView.Name = "tvSummary";

RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

//RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.Client;

//RadGrid1.ClientSettings.AllowExpandCollapse = true;

//Add Summary table

RadGrid1.MasterTableView.Width = Unit.Percentage(100);

GridBoundColumn boundColumn;

GridDropDownColumn ddlColumn;

foreach (DataColumn dataColumn in _dsBudgetVerification.Tables["BVSummary"].Columns)

//these apply to every column in Summary

boundColumn = new GridBoundColumn();

RadGrid1.MasterTableView.Columns.Add(boundColumn);

Focus switches to input when loading new items

The problem is that when I am using the down arrows to scroll through results, when the virtual scroll kicks in a loads more items, the focus gets changed to the input box and hence my scrolling starts again from the top element.

To reproduce:

Go to this page:
1. http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
2. click in the box for the web service example.
3. click the down arrow on your keyboard 11 times.
4. Notice that the selected item is the 1st item in the list when it should be the 11th.
