Hi

Is there a way where i can preserve radgrid and its Template data.

My Scenario is

I retrieve information from Database and bind it to Radgrid and there are few values i bind them to Template columns in ItemDataBound
I am saving Radgrid to Session When i come back to the same page second time i am able to bind the Radgrid with the session howevere not the Template Columns.
Its binding all the template columns all over again which is a time consuming process. If its done for the first time can we just Is there a way i can preserve the complete Radgrid along with Template coulmns
I am not sure if that can be done but just wanted to find out if there is an option

Thank you
Kavya

disabling calendar weekend days

Hi ,

I try to implement the sample http://www.telerik.com/community/code-library/aspnet-ajax/calendar/disabling-calendar-days.aspx ti disable the weekend day.

But the result is very strange. He don't disable the weekend days but the 4 days of the first week and 3 day on the last week.
I say that the sample was from 2007 (little bit old ;-) ) and it was needed to change little think (like i found in other post).
But this change don't solve my problem.

Any issue would be appreciate.

Thanks

Edwin.

Here my code:

    
            // necessary to disable the weekends on client-side navigation 
        
                function OnDayRender(calendarInstance, args) { 
        
                    // convert the date-triplet to a javascript date 
        
                    // we need Date.getDay() method to determine  
        
                    // which days should be disabled (e.g. every Saturday (day = 6) and Sunday (day = 0))                 
        
                    var jsDate = new Date(args._date[0], args._date[1] - 1, args._date[2]); 
        
                    if (jsDate.getDay() == 0 || jsDate.getDay() == 6) {

                        // replace the default cell content (anchor tag) with a span element  
        
                        // that contains the processed calendar day number -- necessary for the calendar skinning mechanism  
        
                        args.Cell.innerHTML = "<span>" + args._date[2] + "</span>"; 
        
                        // disable selection and hover effect for the cell

Export throwing exception

Hi,
I am trying to export a RadGrid data to pdf/excel.
If I use the grid's inbuilt export button then it works fine, but if I call the ExportToExcel() from code behind it throws below exception:
Specified argument was out of the range of valid values on line- radGridShippedOrders.ExportSettings.IgnorePaging = true;

I tried to debug the code and found out that the radGridShippedOrders.MasterTableView.VirtualItemCount is returning 0.

protected void radGridShippedOrders_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{...............}

protected void btnExportToPDF_Click(object sender, EventArgs e)
{
radGridShippedOrders.PageSize = radGridShippedOrders.MasterTableView.VirtualItemCount;
radGridShippedOrders.ExportSettings.IgnorePaging = true;
radGridShippedOrders.ExportSettings.OpenInNewWindow = true;
radGridShippedOrders.MasterTableView.ExportToPdf();

Problem with modal windows that are larger than browser window

Is there any plan to fix the display of modal windows that are larger than the browser window so they can automatically be positioned at the top left of the page instead of the middle? When they are positioned in the middle, you have no way to get to the modal window's toolbar to drag it to where you can see it because the top of the modal window is beyond the top scroll area for the browser window.

see attached image--note that I made the browser window a bit bigger after the modal popped up so you could actually see where it is.

[Solved] How to find div control in edit form server side

I have a RadGrid with an EditForm (defined declaratively in an EditFormSettings-FormTemplate). In that template, I set up a table with one row for each field I'm allowing the user to edit. One of those rows needs to be selectively disabled server side from code behind. I'm trying to do that in the ItemDataBound method. I use the FindControl method on the GridItem passed into that method (parameter

GridItemEventArgs

e, property Item, if it's a GridEditFormItem). If I try to find the label or textbox control that I want to disable, I can find them and set their visibility fine. But if I try giving an Id to the Tr table row tag, or to a div that I wrap around that tag, and try FindControl with the id of those controls, item.FindControl does not find the control. I want to disable the entire table row, not just the controls in that row. How can I do that?

Thanks!

Varying Permissions for Editor

Hello,

We have a client that would like to give some users the ability to override stylesheets by changing colors, fonts, etc. And other users that should not have that ability.

We are being told by our developers that the editor features are either available for all users or none. Is this correct?

If not, how can we allow different user groups to have different access with regards to the editor?

Thanks.
