Questions on UI for ASP.NET AJAX Forum

I have a problem handling the inserts to a grid using "InPlace" edit and "MultiROwEdit".
The Grid is bound to a DataSet (SQL) table. I want to be able to keep inserting multiple rows (items) into the grid and edit them.
The "AllowAutomaticInserts" is set to false. I am catching the insert events in "OnItemDataBound" handler.

In there, I am creating a new 'empty' data row and adding it to the table. Then, I bind the row to inserted item, make it aditable, and finally I change "IsItemInserted" to false to allow for more inserts.

DataTable.AddRow(row); // add row to table

insert_Item.DataItem = row;

insert_Item.Edit =

true;

rdgrd.MasterTableView.IsItemInserted =

false;

This turns the last item in the grid into regular, non-editable item unless Refresh is pressed.
I was wondering wether there is a cleaner way of doing multiple inserts to a grid where all rows are turned into editable items. I could not find any single example exploring this scenario.

Thank you,
Chris

Mass update on grid

I was reviewing another set of ASP.net controls and they provide the ability to Mass update their grid. An example would be that I have a grid populated with data. I would like to use an outside form to find all values in the grid that are X and replace it with Y. Is that possible with the RadGrid? If so, is there an example?

[Solved] Object doesn't support this property or method

I have a form with two RadComboBoxes. One contains a list of states and the other contains a list of counties. Basically, this is a cascading droplist scenario. The OnClientSelectedIndexChanged event on the States RadComboBox is set to ChildRadComboChange shown below. To populate the Counties RadComboBox when a state is selected, I run a LoadCounties method that is triggered by the State.ItemsRequested event. So far, so good.

The problem comes in when the ChildRadComboLoad function runs (shown below). The line childCombo.ClearItems() throws a Microsoft JScript runtime error: Object doesn't support this property or method. The childID contains a valid control id and the childCombo variable is set to the correct RadComboBox (the div, actually).

Any ideas why I can't run this function on the RadComboBox? I have also seen this with some of the other functions like RequestItems?

----Javascript functions

function ChildRadComboChange(sender, eventArgs) {
var item = eventArgs.get_item();
ChildRadComboLoad(sender, item);
}

function ChildRadComboLoad(sender, item) {
var childID = ChildRadComboArray[sender.get_id()];
var childCombo = document.getElementById(childID);
childCombo.ClearItems();
if (item.get_index() > 0) {
childCombo.RequestItems(item.get_value(),false);
childCombo.set_text('');}
else {
childCombo.disable();
childcombo.set_text(ChildRadComboArray[sender.get_id()+'_msg']);
}
}

Sincerely,

Sean M. Severson

Calendar Date doesnt change on navigation

Hi All,

When ever we use navigation controls on calendar to move to a different month or a year, the calendar's SelectedDate object doesnt get updated and it keeps the value of the last selected Date. Why is that so?

Can anyone please explain this happens and is there a way to select the first day of the month everytime the calendar is moved to a different month?

Thanks in advance,

Haroon
