Entity Datasource AllowAutomaticDeletes=true -> Cannot delete "not a valid value for Decimal"

Hi Allow,

I am using an entity datasource on a grid and allowing auto inserts, updates and deletes. Everything seems to be working fine accept while trying to delete i am getting the following:

Error while setting property 'freightRate': '$222.00 is not a valid value for Decimal.'.

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.

I have no code behind (nice) and the column markup looks like:

<

telerik:GridNumericColumn UniqueName="freightRate" SortExpression="freightRate"

HeaderText="Freight Rate" DataField="freightRate" ColumnEditorID="GridNumericColumnEditor1"

FooterText="Freight Rate" NumericType="Currency" DataType="System.Decimal">

</telerik:GridNumericColumn>

Is it because the NumericType? Should i use a Dataformatstring instead? thanks.

[Solved] RadNumericTextBox Display plus sign

Hi, I have an app where I am using a RadNumericTextBox, I am required to allow users to enter positive and negative numbers and the sign must always be shown. I have found no way to have the radnumerictext box to allow entering a positive number as +1.75, negative works fine. This is for an optometry app where numbers are always entered with leading sign.

Anyone know how to make radnumerictextbox allow leading + sign.

Thanks
John

Custom tooltip for one column

I'm looking to add a tooltip to a certain column in my grid, lets says its called 'TestColumn'. How do i go about adding a tooltip to cells in just that column and not the others. At the moment i am applying a tooltip to each cell as follows:

if (e.Item is GridDataItem)

{

foreach (TableCell cell in e.Item.Cells)

{

if (cell.Text != " ") cell.ToolTip = cell.Text;

}

How do i modify this to take the column 'TestColumn' into account?

[Solved] Need CSS help with splitter

Hello Telerik,

I have quite a simple splitter, which makes scrollbars after you move the splitter. (before that it is ok with no scrollbars).
It happens only on Firefox and Chrome. Surprisingly, i.e. seems to manage it nicely.

I guess it is a styling issue.

here is the code (simple aspx with no code behind):

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

What do you advice to change?

Many thanks,

[Solved] Root nodes' text and image invisible after postback

Hi,

I have a tree which is populated by LoadOnDemand (wcf). The root nodes are created server-side when the tree is initialized (initalize is only called once - when the page is not in PostBack).
After a postback, the root nodes don't have a text and an icon anymore. But the child nodes are all ok.

In the screenshot there are several RadDocks. But meanwhile I tested some scenarios and I can tell you that it always happens when
the tree is in an UpdatePanel.

If I add the tree directly to the page, everything is fine after a postback. If I add the tree to an UpdatePanel, the described problem occurs.

In the screenshot the RadDocks are recreated after a postback (and therefor no Initialize is called). Just the left one is the newly created tree which is also initialized.
