Retrieving Checked Rows No Longer Works!

Ever since I upgraded to Q1 2013, I have been unable to retrieve the checked rows in my grid. This exact code below worked fine before, but not does not retrieve the record ID's - any ideas why?

Here is the checkbox column in the grid (and yes, I have datakeynames="record,email" and clientdatakeynames="record":

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">

<HeaderTemplate>

<asp:CheckBox ID="cl" onclick="return check_uncheck (this );" runat="server" />

</HeaderTemplate>

<ItemTemplate>

<asp:CheckBox ID="chk_record" onclick="return check_uncheck (this );" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

Here is the code I to retrieve the record ID's on a button click:

Dim recArray As String = String.Empty

For Each item As GridDataItem In grid_applications.MasterTableView.Items

Dim chk As CheckBox = DirectCast(item.FindControl("chk_record"), CheckBox)

If chk.Checked Then recArray += item("record").Text & ","

Next

check all gridclientselectcolumn checkboxes on load

I am using a radgrid with a gridclientselectcolumn as an input tool to get a list of cost centers to be included in a report.

<telerik:RadGrid ID="gridEntitiesAndCCs" runat="server" AllowSorting="True" AllowMultiRowSelection="true"

AutoGenerateColumns="False" GridLines="None" Width="100%">

<MasterTableView DataKeyNames="FacilityID,CostCtr" AllowMultiColumnSorting="true">

<SortExpressions>

<telerik:GridSortExpression FieldName="ShortName" SortOrder="Ascending" />

<telerik:GridSortExpression FieldName="DeptName" SortOrder="Ascending" />

</SortExpressions>

<Columns>

<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderTooltip="Select all">

<HeaderStyle Width="25" />

<ItemStyle Width="25" />

</telerik:GridClientSelectColumn>

<telerik:GridBoundColumn DataField="ShortName" HeaderText="Entity"

SortExpression="ShortName" UniqueName="ShortName">

<HeaderStyle Width="150" />

<ItemStyle Width="150" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="CostCtr" HeaderText="Cost Center"

SortExpression="CostCtr" UniqueName="CostCtr">

<HeaderStyle Width="100" />

<ItemStyle Width="100" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DeptName" HeaderText="Dept Name"

SortExpression="DeptName" UniqueName="DeptName">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings EnablePostBackOnRowClick="false">

<Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="150" />

<Selecting AllowRowSelect="true" UseClientSelectColumnOnly="true" />

</ClientSettings>

</telerik:RadGrid>

How can I update the grid so that all of the checkboxes in the gridclientselectcolumn and in that column's header are checked when it is initially loaded? In other words, I want the default to be that all rows are selected.

Thank you!

Global skin for one control.

Hi,

In my web application is it possible to globally set a particular skin for a particular control to avoid setting the skin property inline?

Thanks,
Ben.

Object reference not set error on seventh tab

This is the full error
"Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object."

It happens when I click on a tab after clicking on the seventh tab. When I use any of the first six tabs in behaves just fine. Once I click on this seventh tab I get the error when I click on any of the rest of them. If I switch the tab order in the code the problem is still with the seventh tab.

Right now, I'm just asking if this is a known bug or if someone has experienced or heard of it in the past. If it's unheard of I'll post more information.
Version: 2012.3.1205.40
Runtime Version: v4.0.30319

I'd rather not post all the code to the general public right now. I'm getting the account information from our admin so I can submit a ticket.

Resize RadGrid

I need to resize like 5 radgrids using multi page and a rad tab bar so that they fill the available size in the window.

I am using scrolling radgrids with static headers, and paging is in no way allowable. Sorting and editing are used on some, either template columns with asp controls or gridbound columns are being used.

I am registering a startup script and client script block in the code behind using script manager to handle resize and page load calls of this function

function MGridScrollHeight(control , pBuff) {

var windowHeight = 0;

var windowWidth = 0;

if (typeof (window.innerWidth) == 'number') {

//Non-IE

// alert('non ie');

windowWidth = window.innerWidth;

windowHeight = window.innerHeight;

}

else if (document.documentElement && (document.documentElement.clientWidth || document.documentElement.clientHeight)) {

//IE 6+ in 'standards compliant mode'

// alert('IE 6+');

windowWidth = document.documentElement.clientWidth;

windowHeight = document.documentElement.clientHeight;

}

else if (document.body && (document.body.clientWidth || document.body.clientHeight)) {

//IE 4 compatible

// alert('IE 4');

windowWidth = document.body.clientWidth;

windowHeight = document.body.clientHeight;

}

var resizeCont = document.getElementById(control);

var buffer; // BUFFERING

if (pBuff != undefined) { buffer = pBuff; }

else { buffer = 30; }

if ((windowHeight - (resizeCont.offsetTop + resizeCont.offsetParent.offsetTop) - buffer) > 100) {

resizeCont.style.height = (windowHeight - (resizeCont.offsetTop + resizeCont.offsetParent.offsetTop) - buffer) + 'px';

}

else {

resizeCont.style.height = 100

}

This sort of works in IE and busts all telerik related JS in chrome. I tried resizing divs and then using the onGridCreated event as stated here http://www.telerik.com/help/aspnet-ajax/grid-change-scroll-height-at-runtime.html

However this just plain broke, sender was not passed and the methods of accessing height caused JS on the page to fail without triggering IE's or VS's debugger

If there is a method of being able to resize scrolling radgrids to divs ( I am using obj data sources as company requirement) then I would appreciate a pointer towards it.

Hi,
i would like to know if the audio language for captcha codes is available in non-english languages, and in particular for Italian, because our customers are experiencing some difficulties to understand the english pronunciation of the captchas.

Thanks and Regards,

Lose ability to select rows after updating grid with AJAX

I've noticed that whenever I update the RadGrid with AJAX, I always lose the ability to select rows. They don't change when you hover over them either. I really need to be able to use row selection. Thanks

Setting PeekTemplateSettings programatically

I have an object of type RadImageAndTextTile and wish to set the PeekTemplate.

I can create a new TilePeekTemplateSettings object and set the properties I want, but, contrary to what the documentation implies, I cannot apply this to the tile object as RadImageAndTextTile.PeekTemplateSettings is read only!

Also, I cannot find any docs on how to set the PeekTemplate itself from code-behind.

RadHtmlChart rendering axis labels and title under axis instead of chart

I am attempting to display several dynamically generated series in a line chart using the RadHtmlChart, however the axis labels and title are rendering under the axis instead of the chart (DefaultRendering.png). I found a similar question that had the answer of "use the 'AxisCrossingValue' of the YAxis"; when i apply the minimum chart value i get the result in "RenderingWithAxisCrossingValue.png". How can I get the chart to render with both title and labels below the chart area as depicted in "RequiredRendering.png"?

Thanks,

Sean
