Hello,

I work on a project in which I have a radgrid on the main page. On this radgrid a've activated the filter & sort commands. What I would like to do, is to preserve somewhere (in session, viewstate, etc) the state of the filter columns & sort columns (If the user has put some filters, or if the user has sorted the grid by some columns) so when in the future I'll be back on the main page, to put them (the filters & the sort columns) back.
Can this be done?

Have a nice day,
Catalin

FileExplorer stops working after 2012 Q1 update

For some reason, a lot of things appear to be broken using the custom file provider option after upgrading to Q1. I'm using the Custom File Provider that was created by Telerik as an example of how to reference network shares. I'm not sure if it changed with the most recent update, but I know it doesn't work anymore with Q1.

When I attempt to copy a file, I get a permissions error. When I attempt to rename a file, I get a permissions error. I looked at the code a bit and noticed some odd changes. In the GetPath function, it used to pass in the virtual path, but with the update, it's been passing in an empty string. This appears to be the cause of the permissions errors since the path isn't valid.

Is something broken, or was a breaking change released that I'm going to have work around. I didn't see anything in the release notes.

Thanks,
Adam

Item Template ItemDataBound

I was referencing this post earlier: http://www.telerik.com/community/forums/aspnet/grid/radgrid-bind-dropdownlist-after-edit-mode.aspx. The problem with that is my grid item is never of type GridEditFormItem. Here's my method and template code. How can I find and bind the DDL during edit mode of the row?

protected void MyAccountsGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.IsInEditMode)

{

// find the template control

}

<telerik:RadGrid ID="MyAccountsGrid" AllowSorting="true" runat="server" AllowPaging="true" PageSize="20"

AllowMultiRowSelection="true" AllowFilteringByColumn="true" EnableLinqExpressions="true" AllowAutomaticInserts="false" OnItemDataBound="MyAccountsGrid_ItemDataBound">

<MasterTableView TableLayout="Auto" AutoGenerateColumns="false"

AllowFilteringByColumn="true" CommandItemDisplay="Top"

EditMode="InPlace" ClientDataKeyNames="Id,AccountNumber">

<CommandItemSettings ShowAddNewRecordButton="true" AddNewRecordText="Add" />

<telerik:GridTemplateColumn HeaderText="MyDDL" UniqueName="MyDDL">

Empty records when using DataTable as Datasource

Hi ,

I can't seem to bind the source from my datatable. It is not showing anything.

protected void grdDmnDocFolder_NeedDataSource(object o, GridNeedDataSourceEventArgs e)

{

DataTable dt = new DataTable();

dt.Columns.Add("aaa");

dt.Columns.Add("ccc");

dt.Columns.Add("bbb");

DataRow dr = dt.NewRow();

dr["aaa"] = "a";

dr["bbb"] = "b";

dr["ccc"] = "c";

dt.Rows.Add(dr);

grdDmnDocFolder.DataSource = dt;

}

On my aspx page, i already set my OnNeedDataSource event as grdDmnDocFolder_NeedDataSource. What i'm trying to do here is just creating dummy records. What am i missing?

Please help.

Thank you.

Regards,
Dexter

Hi,
I am having issue accessing radwindow object. I am trying access it during radgrid_itemcommandobject.

Setting RadAsyncUpload TargetFolder Error

Hello all!

I am getting a rather frustrating error with the RadAsyncUpload control. When I attempt to set the TargetFolder and TemporaryFolder I am getting a "Object reference not set to an instance of an object" error. It would seem that I am unable to dynamically set these folders. I have tried setting them from server-side, as well as client-side using <%=strAsyncUploadFolder%>. When I attempt to set it from client-side I get an error that says there are invalid characters within the path. Any assitance with this would be very much appreciated. We have several layers where the code exists (ie - local, QA and Production) and I would hate to have to keep changing static paths within the page rather than using nice and neat settings in the web.config file.

I have attached a screen-shot of the error I am getting, if it helps.

I have set "Telerik" theme for radscheduler it's working fine but in the browser 12 CSS files are loading for this particular control. It affects the page response as well as in Internet Explorer(7,8,9) upto 31 individual stylesheets are supported.

Refer the below link

It affect the page size and design.I have added the control in the page layout which resides inside master page. The CSS file count in the application page.

1. Master Page - 2 stylesheet
2. Sharepoint - 4 stylesheet
3. Three RadTab and Radgrid controls - 15 stylesheet
5. RadScheduler - 12 stylesheet

If I have added Radscheduler,RadTab,Radgrid controls in the page totally 27 stylesheets are loaded in the page.So how to reduce the css file of the scheduler control and telerik RadTab,RadScheduler controls ?

Firefox-custom validation disables date column

I have a custom validator attached to a date column in edit on an order entry system to insure that the user doesn't change the date to one already on another order item for that product
if the error is triggered in Firefox (but not in IE, Opera, Safari or Chrome) the date stops popping up for any other item on the page

the column from the grid

<telerik:GridDateTimeColumn UniqueName="ShipDate" DataField="ShipDate" PickerType="DatePicker" HeaderText="Ship Date" DataFormatString="{0:d}" DataType="System.DateTime" >

cvShipDate.ErrorMessage = "Item already ordered on this ship date";

tcShipDate.Controls.Add(cvShipDate);

}

am I going about it the wrong way - or is there - gasp! - a bug?
I'm using the Q3 2011 version

RADScheduler as a Webpart

I'm interested in building a webpart that is essentially the RADScheduler - this will replace the default Sharepoint calendar. I've read several articles on how to create basic webparts with telerik controls, but how would you go about building this webpart as a "fully functional" version of the Scheduler.

Basically I want to be able to give users the option via the webpart editor to select a sharepoint list(s) to pull its information from. The list would need to be a calendar list and extra columns would automatically be reflected by the webpart.

For instance, if the calendar list has a "Color" column then that instance of the scheduler would have a Color selection combo box. If the calendar list had a checkbox field called "Active" then that instance of the scheduler would also have a checkbox field called active.

Another option would be to automatically create a list to store the information when the webpart is initialized. This would likely be the default behaviour.

We've tried several webparts to replace the default calendar component in MOSS and nothing comes close to Telerik's Scheduler. The only problem is that it's a control and not a webpart - a "do it yourself" module sounds good, but I'm oblivious to how it would integrate as a webpart with all of the functionality it possesses.

Please let me know if this type of integration is possible without an extremely large amount of coding.
