calling findControl in OnGridCreated event handler returns null

The findControl method is not able to find controls when called inside of the event handler for the OnGridCreated event as follows. This will cause an error because findControl() returns null. Shouldn't the controls be loaded at this point? Note that I am able to find controls in the row selected/deselected event handlers.

function gridCreated(sender, args)

{

for (var i = 0; i <= sender.get_selectedItems().length - 1; i++)

{

sender.get_selectedItems()[i].findControl("rntbMinDistance").enable();

}

        ChartSeries chartSeries = new ChartSeries();
        chartSeries.Name = "Fleat Composit";

Compressing the response

Hi,

I have a grid which contains people records. If the user expands one person then another nested grid is displayed which has several rows and for each row about 40 columns. Each column has a combo box. When a combo box is opened it displays a third grid. This 3rd grid is bound on the prerender method of the combo in which it resides.

The problem is that once I expand a few people several things happen, all of them bad:
1. The page size grows to over 20MB because the combos bind their grids and each grid is quite big.
2. The IIS process grows to over 1GB of RAM used and stays there even if I close the browser.
3. IExplore grows to about 600MB used.

My biggest problem now is the size of the page, because evidently everything is moving very slow and eventually crashes. What can I do so that each grid is displayed only when the combobox opens?

I tried:

load on demand and it just doesn't get to ItemsRequested.
I also tried to share a combo between all cells in the second grid, but it's too problematic because you never know where to open the popup. And if you manage to calculate based on offsets it just opens in the wrong direction.
I also tried having the third grid load separately once and once each radcombobox opens I copy the innerhtml of the element in the dropdown. That worked, but I have no way of accessing the controls in the third grid because the dom doesn't get updated when I copy the innerhtml.
Also tried binding the third grid via ajax request, but how would I know which radcombobox sent the request since I only have a string parameter to differenciate between them?

I appreciate any other suggestions.

Thanks!

Calendar Control - Multi-month / multi year

Good day

In the process of reviewing the ajax controls.

I have not had an extensive review of the Calendar control just yet but by looking at the examples this does not seem possible and I would most likely go down the custom control route?

My requirement is to display first letter of a month over three years horizontally. Highlighting the month in the year if data is present for that month. See attached sample of requirement.

Am I right to think this is not possible with the Calendar control?

Thanks

RadUploader keeps file copy in 12hive(raduploadhandler) folder

Hi All,
I am using Q2 raduploadhandler and version is 2010.2.714.35. I have some issue when I upload files. It is saving the files in the folder where radhandler is present(12 hive) and we have to give "write" permission for the folder to all site users which leads to security issue. Please give me an alternate solution. Thanks a lot inadvance.

Accessing Selected Grid Cell Value on Client Side

I have the following simple javascript function that fires when the user clicks OK in a RadConfirm window. The function should return the DataKeyValue for the selected row. However it currently returns null and I can figure out why. Can someone please tell me what my mistake was?

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function confirmCallBackFn(arg) {

if (arg == true) {

var grid = $find("<%=RadGrid1.ClientID %>");

var MasterTable = grid.get_masterTableView();

var selectedRows = MasterTable.get_selectedItems();

for (var i = 0; i < selectedRows.length; i++) {

var row = selectedRows[i];

var PackageID = MasterTable.getCellByColumnUniqueName(row, "PackageID")

alert(PackageID);

}

else {

}

</script>

</telerik:RadCodeBlock>

Below is the relevant portion of my RadGrid1 code. My DataKeyName and Column Unique Name are both "PackageID" as required by the JavaScript function.

<MasterTableView AutoGenerateColumns="False" DataSourceID="SqlDataSource2" DataKeyNames="PackageID, Status">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="PackageID"

FilterControlAltText="Filter PackageID column" HeaderText="PackageID"

SortExpression="PackageID" UniqueName="PackageID" DataType="System.Int32"

ReadOnly="True" Visible="false">

RadButtons IE 7 & IE 8

Hi,

I'm having issues with my RadButtons within a RadPane. I have three panes, title, content and button pane at the bottom.

The problem is when I resize the browser to a shorter height, the RadButtons overlap the button pane. This happens only in IE 7 and 8. The odd thing is that the scroll bar does appear noticing the overflow however, it doesn't affect the Radbuttons AT ALL. It seems the z-index or something similar that is causing the overlap with a fixed position as soon as the pane overflows.

Responsiveness of using RadAjaxManager

Hi,
Would like to understand more on the workings of using RadAjaxManager.
Does it still perform a full postback page lifecycle, meaning that the actual response time using RadAjaxManager or a full postback is the same?

The only difference is the perceived response time because only the affected control is updated?
