Collection was modified; enumeration operation may not execute.

Hi,

I was hoping someone could help. I have a radgrid that is populated by a list in code behind and have a checkbox in a Gridtemplate column. There is a button outside the grid that should collect all items that have checkbox checked and add results to a new db table.

This seem to work fine when grid is loaded and not filtered, however when the grid is filtered I get he following error:

Server Error in '/' Application.Collection was modified; enumeration operation may not execute.Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

making non editable the grid column

Hi Team,

I am using the telerik dll version of 2014.2.724.45

I am facing one issue while editing the grid.

Let me explain the issue.

I have a grid with 5 columns in it and has some data populated. I am implementing batch editing(with batch editing type=cell) for this grid.

When I click on the add new record I am inserting a new row, here I don't have any issue.
While updating the record I want to make one column non editable, other columns are editable.
How can I achieve this.Please see the aspx and .cs files below

At what point in the server's page/controls lifecycle should I re-order columns

Scenario

I am creating a user control that contains a RadGrid. The user control will have properties that specify the order of the columns in the RadGrid. I plan on using code similar to the snippet taken from http://www.telerik.com/help/aspnet-ajax/grid-reordering-columns.html

GridColumnCollection cols = grid.MasterTableView.Columns;

GridColumn c = cols.FindByUniqueName(columnName);

if (c != null){

int start = c.OrderIndex;

for (int i= start; i < cols.Count; i++)

{

c = cols[i];

if (i < cols.Count - 1)

c.OrderIndex = i+1;

else

c.OrderIndex = start;

}

Question
1. At what point in the pages life cycle should the code be executed? (i.e. page_load, page_init etc)
2. If I do not want to execute the code based on the page lifecycle, are there event(s) based on the RadGrid's life cycle that can be used to execute the code? (i.e. RadGrid1_Init, RadGrid1_Load, RadGrid1_PreRender, RadGrid1_ColumnCreated etc)
3. Any gotcha's I should be aware about?

Change kendoDropDownList remote dataSource

hi all,

as per title, how to make this possible?

var newDataSource=new kendo.data.DataSource({

transport : {

read : {

url : context+"/master/common/listLocationByCountry/"+data.country.id+"?marketDifferentialId="+data.id+"&locationId="+data.location.id

}

});

newDataSource.read();

var locationName = data.location.name;

var locationValue=data.location.id;

var locationDropDown = $("#locationId").data("kendoDropDownList");

locationDropDown.setOptions({ dataTextField: "name", dataValueField: "id" });

locationDropDown.setDataSource(newDataSource);

$("#locationId").val(locationValue).data("kendoDropDownList").text(locationName);

the problem is the dropdown is still access url from old datasource to pupolate.

root menu without submenu has the error "Input string was not in a correct format."

I got that error when I am building a menu based on a sqlDataSource with the following SelectCommand:
SelectCommand="SELECT '1' AS id, null as pid, 'A&SI' AS text, '' as url
UNION ALL
SELECT '2', null, 'P&P',''
UNION ALL
SELECT '3', null, 'T&E',''
UNION ALL
SELECT '4', null, 'FTR',''
">

However, it works if I add two union statements like below to the end:
SelectCommand="SELECT '1' AS id, null as pid, 'A&SI' AS text, '' as url
UNION ALL
SELECT '2', null, 'P&P',''
UNION ALL
SELECT '3', null, 'T&E',''
UNION ALL
SELECT '4', null, 'FTR',''
UNION ALL
SELECT '7', null, '',''
UNION ALL
SELECT '8', '7', '',''
">

The selectcommand eventually will be replaced by a stored procedure and I do not want to fix the problem by manipulating the procedure using dirty tricks like this.

Any ideas? Thanks!!

Context Menu item contentTemplate not showing

Windows 7 pro x64
VS2008 web page
Telerik UI for ASP.NET AJAX Q2 2014 - Bin35

In this simple page, there is a context menu with 3 items
the third item uses a content template.
Right click over the text to show the context menu.
The third item does not show up in the browser but is rendered along with an empty iframe. why?

my goal is to put some text and a textbox (html element) where the text would normally be in a radMenuItem.
something like
<content Template>part number contains: <input type="textbox" /></contentTemplate>
so that the user can right-click and click in the textbox and type something in. (I can catch the ENTER keystroke and do the post back)

Collapse all nodes when filter is empty

Hello,

I am using the control to replace a old control we made ourself and that have the same behaviour as this DropDownTree. I have suscceeded yto d pretty much everything I wanted. There is only one thing I want to do, I want all the node to collapse when the filter is empty.
I have tried several solutions, my closest one is this one, but is not working proprely. Sometimes it works, sometimes it does not :

I have attached to the DropDownTree OnClientLoad client side event this function :

function loadTreeView(sender, args) {

var dropdowntree1 = $find("<%=ddtList.ClientID%>");

var tree = dropdowntree1.get_embeddedTree();

$(".rddtFilterInput").keyup(function () {

if ($(".rddtFilterInput").val() == '')

treeCollapseAllNodes(tree);

}

I've tryed that too : $(".rddtFilterInput").on('input',function () {...}); But no success either...

I can see that it collapse the nodes but right after they are expanding again.
I also tried to cancel the OnClientNodeExpanding event when the filter is empty but no success here either...

Do you have any solutions that realize what i'm trying to do ?

Thanks

Data does not appear in grid when creating grouping in code behind page

I have an issue when trying to set up grouping in the code behind (vb.net) in that the data does not appear.
If I set up the grouping on the aspx page the records show up.
I have tried adding the datasource and databind before and after this code but I never get any records to appear.
I want to be able to dynamically turn certain grouping on or off depending on the user selection.
Can you tell me why the records are not showing up when I use the code behind page to create the grouping?

RadGrid1.MasterTableView.GroupByExpressions.Clear()
Dim ShowFacilities As CheckBox = ctlOptions.FindControl("cbShowFacilities")
If ShowFacilities.Checked Then
Dim ge1 As New Telerik.Web.UI.GridGroupByExpression
Dim gf1 As New Telerik.Web.UI.GridGroupByField
gf1.FieldName = "Facility"
gf1.HeaderValueSeparator = String.Empty
gf1.HeaderText = "Facility - "
ge1.SelectFields.Add(gf1)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge1)

Dim ge2 As New Telerik.Web.UI.GridGroupByExpression
Dim gf2 As New Telerik.Web.UI.GridGroupByField
gf2.FieldName = "Name"
gf2.HeaderValueSeparator = String.Empty
gf2.HeaderText = " "
ge2.SelectFields.Add(gf2)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge2)

Else
Dim ge2 As New Telerik.Web.UI.GridGroupByExpression
Dim gf2 As New Telerik.Web.UI.GridGroupByField
gf2.FieldName = "Name"
gf2.HeaderValueSeparator = String.Empty
gf2.HeaderText = " "
ge2.SelectFields.Add(gf2)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge2)

End If

RadGrid1.DataSource = MyDataSource
RadGrid1.DataBind
