Set All Rows Auto Height

I'm attempting to load an Excel spreadsheet into the Spreadsheet control (which, I've been able to do dynamically). However, our spreadsheets have more than a single line of text and therefore need to have auto height set to the entire worksheet versus per row. How would we go about doing this? I've read the documentation about setting specific row(s) auto-height, but nothing for setting the entire worksheet to have auto-height rows.

Cannot find items in RadToolBar when a RadToolBarDropDown is in the collection

The following code does not work when the toolbar contains any RadToolBarDropDown objects:

RadToolBar1.Items.FindItemByValue("buttonValue").Visible = true;

It results in the following exception:

Value property is not supported by RadToolBarDropDown

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Exception: Value property is not supported by RadToolBarDropDown

This makes using it very difficult (indeed impossible).

I note that this has come up before but it seems like the problem is being ignored

RadGrid - Checkbox column - databound - get + set value via javascript

Hi,

I have a databound radgrid and I need to get and set the value of a checkbox column client side.

I'm using the following for the other columns, which I have adapted from code found on this site.

var myMasterTable = Grid.get_masterTableView();
var myCell = myMasterTable.getCellByColumnUniqueName(myMasterTable.get_dataItems()[myRowIndex - 1], ColumnName);
var myCellValue = myCell.innerHTML;
if (myCellValue == " ") { myCellValue = ""; }
return myCellValue;

But unlike the other columns it returnsthe below html and not the actual value?

"<span class="aspNetDisabled"><input id="grid_Properties_ctl00_ctl04_ctl50" type="checkbox" name="grid_Properties$ctl00$ctl04$ctl50" checked="checked" disabled="disabled"></span>"

How do I get the checked state and also set the checked state via javascript? Is their abuilt in method for this?

Thanks in advance

DropDownTree Set Selectable Property

I am using the DropDownTree to display nested items. Sometimes parents are selectable, sometimes they are not.

In the dataset being returned, I have 3 columns: Text, Value, IsSelectable.

Is there a way to pass the IsSelectable property through to the DropDownTree and then make the items selectable based on that property? It seems like it only takes Value and Text.

Please let me know if there is a way for this to work! Thank you!
