Grid rows don't close ordinarily if the batchEditClosing is cancelled

Greetings,

I have a batch mode grid that's required to be able to display a dialog when the user is editing a row, and the user will interact with the dialog in some way.
I used a RadWindow for the dialog, and because the grid closes the currently edited row if the user clicks outside the row, I added the following code to prevent the grid from closing the currently edited row while the dialog is shown:

function dialog_beforeShow(sender, args)

{

grid.add_batchEditClosing(grid_batchEditClosing);

}

function grid_batchEditClosing(sender, args)

{

args.set_cancel(true);

}

function dialog_close(sender, args)

{

grid.remove_batchEditClosing(grid_batchEditClosing);

}

After the dialog is closed, I find that the row doesn't close if I click with mouse anywhere.
It only closes if I open another row for editing.

radgrid updateCommand reload into session variable

Hi there,

I am attempting to refresh a datatable with the latest updates from a radgrid.

Steps

1. Two Rows exist

2. User Clicks "edit"

3. Two columns become editable

4. User edits 1 or both values clicks "update"

5. Within myGrid_UpdateCommand session variable gets updated.

6. Currently only returns newly edited row, ignores row not edited.

7. WANTED: to always return all the rows, edited and unchanged.

Code

Protected Sub rgTaxRate_UpdateCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs) Handles rgTaxRate.UpdateCommand

Dim newDataTable As DataTable = New DataTable

' build column names

For Each col As GridColumn In rgTaxRate.Columns

Dim dCol As DataColumn = New DataColumn(col.UniqueName)

newDataTable.Columns.Add(dCol)

Next

; attempt to create row

For Each row As GridDataItem In rgTaxRate.Items

Dim dr As DataRow = newDataTable.NewRow

For Each col As GridColumn In rgTaxRate.Columns

dr(col.UniqueName) = row(col.UniqueName).Text

Next

newDataTable.Rows.Add(dr)

Next

Session("MyTempTable") = newDataTable

this is based on another thread I saw but I am unsure for the life of me how they got it to work.

Here is my aspx code

<telerik:RadGrid OnItemEvent="rgTaxRate_ItemEvent" ID="rgTaxRate" Width="100%" AllowPaging="True" PageSize="8" runat="server" AllowSorting="True" GridLines="None"

<MasterTableView ShowFooter="false" DataKeyNames="TaxID" EditMode="InPlace" Width="100%" CommandItemDisplay="Bottom" HorizontalAlign="NotSet" AutoGenerateColumns="false">

<CommandItemTemplate>

<div style="padding: 5px 5px; text-align:left;">

<asp:LinkButton ID="reloadTaxes" Text="Reset to Defaults" CommandName="Reload" runat="server" OnCommand="lbReload_Command"></asp:LinkButton>

</div>

</CommandItemTemplate>

<Columns>

<telerik:GridBoundColumn DataField="TaxID" HeaderText="TaxID" UniqueName="TaxID" SortExpression="TaxID" Display="false"></telerik:GridBoundColumn>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox Width="128px" runat="server" ID="rgTaxRate_Description" MaxLength="20" Text='<%#Eval("TaxDescription") %>'></telerik:RadTextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="TaxRate" UniqueName="TaxRate" HeaderText="Tax Rate" SortExpression="TaxRate" ItemStyle-Width="56px" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Left">

<ItemTemplate>

<%#DataBinder.Eval(Container.DataItem, "TaxRate")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadNumericTextBox Width="56px" ID="rgTaxRate_Amount" Type="Percent" MinValue="0" MaxValue="100" MaxLength="3" NumberFormat-DecimalDigits="0" NumberFormat-GroupSeparator="," Culture="en-US" runat="server" DbValue='<%#Eval("TaxRate") %>'>

</telerik:RadNumericTextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings></ClientSettings>

<FilterMenu EnableTheming="True">

<CollapseAnimation Duration="200" Type="OutQuint"></CollapseAnimation>

</FilterMenu>

</telerik:RadGrid>

<telerik:GridTextBoxColumnEditor runat="server" ID="rgTaxRate_Amount">

RadGrid demo code

Hi,

I'm looking at the demo code for RadGrid (http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/edit-form-types/defaultvb.aspx)

and when I try to run it, I get a System.ArgumentOutOfRangeException error on:

Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs) Handles RadGrid1.PreRender
If Not IsPostBack Then
Me.RadGrid1.MasterTableView.Items(1).Edit = True <-- this line is throwing the error
Me.RadGrid1.MasterTableView.Rebind()
End If
End Sub

I haven't modified any of the demo code, and wondering how to fix this.

Thanks in advance.

Declarative Binding and GridCheckBoxColumn

Hello,
I have implemented the client-side declarative binding sample but can not get the GridCheckBoxColumn to show as checked regardless of the Sql value. I see that the http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/declarative/defaultcs.aspx sample has the same problem. How can I get this to work? I tried implementing RowDataBound but this did not help. Thank you.

function RowDataBound(sender, eventArgs) {

if (eventArgs.get_dataItem()["Discontinued"] == true) {

var checkbox = eventArgs.get_item().get_cell("Discontinued").getElementsByTagName("input")[0];

checkbox.checked = true;

}

RadContextMenu problem with new chrome version

Hello, Since this morning, when our browsers (chrome) updated to version 32.0.1700.76 m, we are experienced a problem with the RadContextMenu placement when the page is scrolled down (pic2.png). Checking for possible errors we found the following: "body.scrollTop is deprecated in strict mode. Please use 'documentElement.scrollTop' if in strict mode and 'body.scrollTop' only if in quirks mode." We checked in your demo page and there is the same problem. We tested it in other browsers and it's fine... Thanks, Rodrigo
