Hi,

I using some ampersand characters in my treeview, but when I validate my page with http://validator.w3.org I get some error on the ambersand characters.

Line 146, Column 132: StartTag: invalid element name

…x?Category=$VingepumpeMindre250&amp;menyCategory=1,1">Vingepumper, <250 bar</a>

Is it possible to make the treeview control to show ambersand?


Best regards

when i try to bind the Grid view using the Pagemathods or webmethods, everything works well and its fast.
but the above is true only if my web method returns not more than 20 rows of data.
as soon the webmethod returns more than 20 rows, the RadGrid control simply doesnt bind or refresh, as if no action was made !?
at first i thought that it might be just slow so i tried waiting for more than 30min and the result is the same...

if i do the same thing but bind the grid on server side using the NeedDataSource event then it loads more than 20 rows, but because the performance is much faster on client side binding, i need to make it work on client side.

using the visual studio 2010 debugger i followed step by step and a strange thing happens the ajax call to the webmethod is beingsent ok, and the pagemethod / webmethod is executed ok and returns the data, once the data is returned to radgrid its like it swallows it and no further action happens nor any other client side events are fired or javascript code is executed...

Please help, i spent almost a week on this issue and cant find a solution... many thanks in advance...

please see below the grid code and pagemethods that i am using:

Hi,

I have a Telerik control inside an ASP.NET UserControl. The UserControl is deployed to the Sharepoint 2010 site.

Currently I am receiving the error:- "Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. The system cannot find the file specified."

What I have done so far:
- I have added the Telerik.Web.UI.dll to the GAC.
- I have added it to the SafeControls list
- I have checked that all the Ajax required tags are present (as in http://www.telerik.com/help/aspnet-ajax/moss-install-aspnet-ajax.html)

Is there something else I am missing??

Note* I am aware that there are separate products for Sharepoint but I want to use my exisiting Telerik controls.

Thank you,

KS

Hi,

i have a radgrid with autogeneratedcolumns option as true. i disabled the viewstate for grid.  whenever a column reorder happens, i have to move some more columns.i am trying to move the extra columns through server side implementation. i am doing this in Prerender event of radgrid. The drag and drop column is moving to dropped position. However i am unable to move the extra columns. please help me out regarding this. i am trying for this for whole day but in vain :(

i made the following settings for my grid
EnableColumnsViewState="true"
AllowColumnsReorder="True",  ReorderColumnsOnClient="false"

grid PreRender code for moving the extra columns
protected void grdSummary_PreRender(object sender, EventArgs e)
{
//Holds the Unique names of columns to be moved
string[] extraColumns =new string(commasepratedColumnNames)
//column that was dragged and dropped
GridColumn mainColumnObject = grdSummary.MasterTableView.GetColumn("34");
                        index = mainColumnObject.OrderIndex;
                        foreach (string columnUniqueName in extraColumns)
                        {                            

                            grdSummary.MasterTableView.SwapColumns(columnUniqueName, mainColumnObject.UniqueName);                            
                        }
                        grdSummary.MasterTableView.Rebind();

Hi,
Teleric Radgrid supports reordering grid columns on client side. I have a requirement like if i move a column from position m to n, then columns in m+1, m+2 should move to n+1 and n+2 positions automatically(through code).

can you please help me out how can we achieve this using the javascript methods provided.

I came to know that ColumnMovingToLeft and ColumnMovingToRight property javascript methods are invoked when we reorder a column.

Thanks in advance

is possible that when you add a dynamically Radok not have to re-create existing ones, the postback does not affect existing

Hi Guys,
       I am loading 800000 records in the radgrid with custom paging, it's throwing timeout error, How can i work Radgrid with large number(800000) of records, this is my requirement. but i can able to bind 200000 records in radgrid without any timeout or performance issue, so can anyone knows please suggest me  

These are the following steps i have tried in my code: (Kindly note this, this radgrid i am using with in sharepoint 2007 as well as 2010)
1. i am using custom paging and set the virtual item count is 800000 and set the pagesize is 50
2. i am storing 800000 records in viewstate, not binding all 800000 records in radgrid, i am binding just 50 records at the time of loading the radgrid
3. if i change the paging in the radgrid, based on the page index i am getting 50 records from viewstate and bind it in the radgrid (for ex: current pageindex is 5 means i took 201 to 250)
4. telerik support team tell, don't use the viewstate, so i am storing all 800000 records in property bag even though it's throwing time out error
          which is the best way to store all 800000 records and bind 50 records in RadGrid without performance issue, please tell me what i need to do?
