RadAjaxManager ResponseScripts are empty after a PostBack()

Hi,

I've a page which contains a panel with a button to show/hide another panel and proceed to their update in the same time. I use RadAjaxManagerProxy and AjaxSetting to do that.

When I click the first time on the button, the update works fine with loading panel, etc... and after that the button just do a show/hide interaction with JQuery function that I add in ResponseScripts of the RadAjaxManager of the Page.

Since that all work fine. But when in the header of my masterpage I click on a button and it invokes a PostBack, the responseScripts of the RadAjaxManager is empty and my JQuery interaction doesn't work.

I've check the collection of ResponseScripts before and after and I think postback clear it. Can you help me please ?

Problem with Copy and Paste when using GridNumericColumn instead of GridBoundColumn

I am using the Copy and Paste example mentioned in this thread (and in other copy and paste threads). The only thing that I change is to set AutoGenerateColumns="False" and list down the columns. Everything works like the original example.

Code that works:
ASPX

<telerik:RadCodeBlock ID="rcb1" runat="server">

<script type="text/javascript">

// ***** Begin Paste from Excel scripts.

var lastFocused;

function pasteFromExcel() {

if (!lastFocused) return;

var clipData = window.clipboardData.getData('Text');

var crlf = String.fromCharCode(13) + String.fromCharCode(10);

var table = clipData.split(crlf);

for (var tRow = 0; tRow < table.length - 1; tRow++)

table[tRow] = table[tRow].split(String.fromCharCode(9));

Array.remove(table, table[table.length - 1]);

fillTable(table);

}

function fillTable(table) {

var pCell = lastFocused.parentNode;

var pRow = pCell.parentNode;

var pBody = pRow.parentNode;

var maxRows = pBody.rows.length;

var maxCols = pRow.cells.length;

hasChanges = true;

for (var row = 0; row < table.length; row++) {

for (var col = 0; col < table[row].length; col++) {

var cCellIndex = pCell.cellIndex + col;

var cRowIndex = pRow.sectionRowIndex + row;

if (cRowIndex < maxRows && cCellIndex < maxCols) {

var cCell = pBody.rows[cRowIndex].cells[cCellIndex];

var pInput = cCell.getElementsByTagName("input")[0];

pInput.style.backgroundColor = "#F7FAFF";

pInput.value = table[row][col];

}

function gridFocus(e) {

e = e || window.event;

var target = e.target || e.srcElement;

if (target.tagName.toLowerCase() == "input" && target.type.toLowerCase() == "text")

lastFocused = target;

}

function clearCells(sender) {

var radGrid = $get('<%= RadGrid1.ClientID %>');

var inputs = radGrid.getElementsByTagName("input");

for (var el = 0; el < inputs.length; el++) {

if (inputs[el].type == "text") {

inputs[el].value = "";

inputs[el].style.backgroundColor = "";

}

// ***** End Paste from Excel scripts.

.CS

protected void Page_Load(object sender, EventArgs e)

{

for (int i = 0; i < RadGrid1.PageSize; i++)

RadGrid1.EditIndexes.Add(i);

}

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

{

if (e.Column is GridBoundColumn)

e.Column.Visible = (e.Column as GridBoundColumn).DataField != "ID";

}

protected void RadGrid1_ItemUpdated(object source, GridUpdatedEventArgs e)

{

e.KeepInEditMode = true;

}

Now when I change the columns in the grid from GridBoundColumn to GridNumericColumn, here's what I find out:

1. There is an extra <span> element in the GridNumericColumn so I had to update function fillTable to go to an extra parentNode. The data is pasted on the correct cells but if you click on those cells, it removes the pasted data and reverts to the original data.

2. The edit cells changed from an inset border and each cell is slightly indented to a thin solid border where the first column is slightly indented and all succeeding columns mis-aligned. I can deal with the border style, I need to know how to remove the slight indent in the first column or at least make it look like the GridBoundColumn example.
