Hello,

How do you set default insert value to today for a GridDateTimeColumn in a RadGrid configured to use Batch edit mode?

 

Thank you.

Hi Amy,

You can set it in the markup like this:

<telerik:GridDateTimeColumn DefaultInsertValue="Today"></telerik:GridDateTimeColumn>

Thank you for the response Maria.  Unfortunately, this does not work on my end.  When I click the button in the grid to add a new record, the GridDateTimeColumn simply displays the text "Today" in the cell.

I thought that I might have to set this value in one of the client side events such as 'OnBatchEditOpening'.  However, I'm not sure how to distinguish between insert and edit mode in this event, and also I'm not sure how to get a reference to the RadDateTimePicker in the GridDateTimeColumn to set Today's date.

Hello Amy,

Try the following code snippet in order to set current date to DatePicker when in Insert mode.
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataInsertItem && e.Item.OwnerTableView.IsItemInserted) 
    {
        GridDataInsertItem insertItem = (GridDataInsertItem)e.Item;
        (insertItem["DateTimeColumn_UniqueName"].Controls[0] as RadDatePicker).SelectedDate = DateTime.Today;
    }
}

Hello Maria,

From what I understand, a server-side event like ItemDataBound ‚Äčis not triggered because Batch Edit is a client-side oriented mode and the entire editing is handled on the client-side.  Thus I don't believe your suggestion above will work. 

Can you please provide some guidance on how to set the default insert value to today for a GridDateTimeColumn in one of the client-side events?

Much appreciated.

Hello,

With batch editing you can use the following:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    GridTableView masterTable = ((RadGrid)sender).MasterTableView;
    GridDateTimeColumnEditor editor = masterTable.GetBatchColumnEditor("OrderDate") as GridDateTimeColumnEditor;
    RadDatePicker picker = editor.PickerControl;
    picker.SelectedDate = DateTime.Today;
}

Thank you for the suggestion, but this is not working on my end.  Is it possible for you to provide a runnable example where this is working?  Or, suggest a way to do this in one of the client-side events?

Thank you,

Amy

Hi Amy,

It appears that we have an issue with setting default insert value when batch editing is enabled and this issue is logged in our system for further investigation.

Meanwhile you can handle the client OnRowCreated event and apply the default date like this:
function RowCreated(sender, args) {
                           if (args.get_itemIndexHierarchical() < 0) {
                               args.get_tableView().get_dataItems();
                               var cell = args.get_tableView().getCellByColumnUniqueName(args.get_gridDataItem(), "HireDate");
                               args.get_tableView().get_owner().get_batchEditingManager().changeCellValue(cell, new Date().toString());
                           }
                       }

I hope this helps.

<telerik:RadGrid ID="RadGrid1" runat="server" AllowAutomaticInserts="true" DataSourceID="SqlDataSource1">
    <MasterTableView EditMode="Batch" DataKeyNames="EmployeeID" CommandItemDisplay="Top">
        <Columns>
            <telerik:GridDateTimeColumn UniqueName="BirthDateColumn" DataField="BirthDate"></telerik:GridDateTimeColumn>
            <telerik:GridTemplateColumn Display="false">
                <ItemTemplate>
                    <%(RadGrid1.MasterTableView.GetColumn("BirthDateColumn") as GridEditableColumn).DefaultInsertValue = DateTime.Now.ToString();%>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Thank you Maria and Edward for your suggestions.  Please see the results of my test below:

  1. Maria's suggestion using the OnRowCreated event.

    - Sets the initial date with the proper formatting.

    - However, the date is not saved when the Save button is clicked.  Note that I am saving the grid data using the method as described here - http://www.telerik.com/forums/how-do-i-save-2-radgrids-by-only-1-outside-button.

  2. Edward's suggestion using an additional hidden column.
    - Sets the initial date, but does not have the proper formatting.

    - The date is not saved when the Save button is clicked.

Almost have a working solution...  But is seems that the BatchEditingManager doesn't think that there are table changes when setting the initial date this way.

Hi Amy,

After fixing the bug below you will be able to achieve the required functionality:

http://feedback.telerik.com/Project/108/Feedback/Details/172538-setting-defaultinsertvalue-does-not-work-for-a-batch-editing-grid

We increase its priority and I hope that the fix will be available in the next official release of the controls.
