Edit multiple rows, postback only edited/new rows?

I have a very large grid and I'm researching ways to improve performance.

Currently, the users can do the following, and I'd like to keep as much of this behavior as possible:

Double clicking a row switches the entire row to edit mode.
Able to edit multiple rows at the same time (paging is not enabled)
Clicking an 'Add' button on a row inserts a new blank row under the row.
Multiple new rows can be added.
No changes are committed until the user clicks a save button for the whole grid.

Is it possible to customize the grid meet these requirements? Also, is it possible to minimize the network traffic by only sending the new or edited values to the server instead of the whole grid? Thanks.

Sort Problem in RadGrid

Dears,

I have a RadGrid with Enabled sorting on columns and I am using a RadAjaxManger in page to update RadGrid data. I noticed that clicking on any column in order to sort caused a page postback. So, what should I add to RadAjaxManager in the page to prevent page post back?

RadUpload bug deleting the file name

Hello,

I installed the latest version of Rad Controls for ASP.Net. After selecting a file name using the browse/select dialog, I was attempting to manually delete and modify it.
However when I click on the text box, the file name is padded with many spaces (why???) and while I am deleting these spaces appended at the end (using backspace button on keyboard), characters from the file name are actually deleted. In addition to that, while pressing the backspace button and thus deleting, somehow the full path to the file starts showing in the text box!

Are you aware of this bug? Is there any workaround?

I was expecting to be able to highlight the file name and delete several characters. This is not possible.

Regards,
M. Rusu

Rad Grid Export to Excel Problem

Hi Telerik Team,

I want to Export the Rad Grid data to the Excel Sheet, I have added a link button to the Rad Grid dynamically. For Exporting the Rad Grid data to the Excel Sheet i have placed the rad grid inside a "RadAjaxPanel", When i place the Rad grid Inside the RadAjaxPanel the entire data is being Exported to the Excel sheet, but the link button that i have added dynamically to the Rad grid is not doing any post back (My requirement is on clicking this link button it will get the DataKey and based on the DataKey value it will fetch the Records from the Database and display in the RadGrid in a POP-up), but when I remove the Rad Grid from the RadAjaxPanel the data is not being Exporting to the Excel Sheet it is giving the Following Error:

"Server Error in '/' Application.

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

In this Case the Link Button that i have added dynamically is doing the Post back and displaying the Data in the Pop-up.
This is the Code that i am use for Rad Grid for opening pop-up on Link button Click:

"<telerik:RadGrid ID="rgAccountDetails" runat="server" AllowPaging="True" PageSize="10" AllowFilteringByColumn="True" AllowSorting="True" Visible="false"

Skin="Vista" OnPreRender="rgAccountDetails_PreRender" OnColumnCreated="rgAccountDetails_ColumnCreated" OnGridExporting="rgAccountDetails_GridExporting"

OnItemCommand="rgAccountDetails_ItemCommand" OnPageIndexChanged="rgAccountDetails_PageChanged"

OnExcelMLExportRowCreated="rgAccountDetails_ExcelMLExportRowCreated">

<ExportSettings ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true">

<Excel Format="ExcelML" />

<Pdf FontType="Subset" PaperSize="Letter" PageWidth="18in" PageHeight="150in" />

</ExportSettings>

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView DataKeyNames="AccountID" CommandItemDisplay="Top">

<CommandItemSettings ShowExportToWordButton="true" ShowExportToExcelButton="true"

ShowExportToCsvButton="true" ShowAddNewRecordButton="false" ShowExportToPdfButton="True" />

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

</MasterTableView>

</telerik:RadGrid>"

In the above code the link button is doing Post Back and fetching the data and display in the Pop-up, but Rad grid data is not exported to the Excel sheet.

"<telerik:RadAjaxPanel ID="RadAjaxPanel2" runat="server" LoadingPanelID="RadAjaxLoadingPanel2"

ClientEvents-OnRequestStart="requestStart" HorizontalAlign="NotSet">

<telerik:RadGrid ID="rgInvoicedetails" runat="server" AllowPaging="True"

PageSize="7" AllowFilteringByColumn="True" AllowSorting="True" Visible="False"

Skin="Vista" OnItemCommand="rgInvoicedetails_ItemCommand" OnColumnCreated="rgInvoicedetails_ColumnCreated"

OnPageIndexChanged="rgInvoicedetails_PageChanged" GridLines="None">

<PagerStyle Mode="NextPrevAndNumeric" />

<ExportSettings FileName="InvoiceReports" ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true">

<Excel Format="ExcelML" FileExtension="xlsx" />

<Pdf FontType="Subset" PaperSize="Letter" PageWidth="18in" PageHeight="150in" />

</ExportSettings>

<MasterTableView DataKeyNames="InvoiceID">

<CommandItemSettings ExportToPdfText="Export to Pdf" />

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

</MasterTableView>

</telerik:RadGrid>

</telerik:RadAjaxPanel>"

In the above code the link button is not doing Post Back and is not able fetching the data and display in the Pop-up, but the Grid data is Exported to the Excel Sheet.

Please help me.

Thanks,
Arvind.

Image Optimisation

I know that you guys have been using sprites in skins for an age now, but I stumbled across the Sprite and Image Optimization FrameWork on CodePlex and wondered if anyone from telerik towers wanted to comment on its usability with controls like RadToobBar and RadTreeView where the developer may well be requesting a number of images for the control in question.
