I have a grid that has a GridDateTimeColumn, and I'm trying to apply a default filter on page load.  I do have the AllowFiltering property set to true on the column, as well as the grid itself and I've also set the current filter condition [this part works].  I have a data source that is loaded with a large date range, but the users are requesting to hide most of the data so it's available for searching.  I've tried following this example: http://www.telerik.com/community/forums/aspnet-ajax/grid/default-filter-on-initial-load-for-griddatetimecolumn-with-rangefiltering.aspx but it didn't apply the filter - it just fills the date in the filter box.

I should also note, that I am trying to apply the filter in my code-behind.

Hello,

I have the exact same issue reported over two years ago here - http://www.telerik.com/community/forums/aspnet-mvc/combobox/dropdownlist-does-not-change-its-input-value.aspx

Using the plugin they are also using, I have found changes to dropdowns were not being tracked.  I believe the root of this issue is from this user's post:

"However, using .val() does not fire a change event. In html's select dropdown and not telerik's dropdown, selecting a different value fires a change event. In your case, you change the value via .val() but forget to trigger a change event which I think you should do via $('#').val().change();"

Telerik's reply back in sept 2011 was that this would be forwarded to the developers.  I am not interested in wiring up a valueChanged event handler to every dropdownlist, and was hoping to get an update on this issue.  Shouldn't telerik's dropdown follow the same event pattern as a standard html dropdown in terms of firing events?  If there's a reason it shouldn't, is there any global solution for this issue?

I have a self-referencing hierarchical grid defined as follows:



Each item can have 0 or more children.  When I reorder the columns, the root level entries (indicated as "Parent Col Val" below) are reordered, but the child column values (e.g., "Child Col Val") remain in the order in the grid defintion.  For example, if I have the initial layout defined as:


I then reorder the columns.  While the parent values reorder properly, the child ones do not.


This also occurs when I the saved grid settings are reloaded during Page_init (e.g., the parent items are ordered in the saved order, but the child columns are ordered as they're defined).  Attached are screenshots showing the grid before and after the columns are reordered to better describe the behavior I'm experiencing.

Is this a bug w/ the grid?  I would expect that self-referencing grids would automatically reorder the child tables as well.  If this isn't a bug, what is required in order for the columns to be ordered properly?

Hi,
I have a 2 Level(Parent & Child) Treeview.
and i set Parent Node ExpandMode = TreeNodeExpandMode.ServerSide;

How do we set Checked=true if user has previously selected Child nodes (lets assume i am getting the previous selected values from the Database)


Thank you

which answered my question, and was able to resolve my issue.



Sometimes, admittedly, I am not the brightest bulb on the planet, but for the life of me I just can't seem to get what I think is a rather simple TreeView to work.

I have data from an SQL data source which is broken down into categories, i.e.

Basically, I want this to appear in a tree view with the "Id" Text being the primary (expandable) node (i.e. Clauses), and the "text" being the secondary node which will appear when the user expands the primary node.







I've fiddled around w/ the various online examples, but either I get an error telling me "These columns don't currently have unique values" (if I leave the ParentId column blank when the Text column is blank) or I get nothing at all. I've tried duplicating the online example:















but without "seeing" the underlying data, I'm not sure how to structure my dataset to duplicate this functionality.







Can someone provide a simple example of the proper TreeView syntax?

Trying to export my sub grid as well but it seems to not work, following the instructions found on teleriks sites but to no avail.

Mu grid is wrapped in update panel and it works to export the main grid just fine just no sub grids come along.  Here is the code I put in to take care of the issue but nothing.  I am using all the radgrid advanced data binding methods.

Hi,
I would like to set 'Auto' width of grid.. because my Page contains left sidebar with hide and show functionality and I have grid with 15 columns.
When I bind the data to grid with '100%' width, it goes outside of design and If I set specific width to grid then it not display properly b'coz of the side bar hide and show functionality.
If same grid contain less column then it works properly..so please give me proper solution.
thank you.

Hi - 
I'm looking for suggestions on how to best achieve the following using the AsyncUpload control.

Our users are uploading excel files. I need to verify there are certain columns in the excel file. If they are all present, then it will pull data from the spreadsheet and put that into a database. Then the file itself will be put into the database.

At what point should I do the verification for the columns? Can I do this error checking on the temporary file?  There is no reason for the excel file to ever make it into the database if the columns are not present and the data cannot be uploaded if it isn't.

Thank you in advance.

Hi,

I am creating a new dashboard page with RadTabstrips and each tabs loading an individual set of Raddocks dynamically (these docks are movable and thier state are saved in the DB).
The issue we are facing while trying to achieve this is since we are loading the Docks dynamically and maintainig its state through docklayout's loadstate and savestate method, we are suppose to add the dock back in Page_Init event.
Also we can get the required dock details from DB based on current selected Tab only but we cannot get the selected tab index in Page_Init. If we get the selected index in page_load and add docks there then the state of the dock is not retained.

Please suggest us a solution here, following are some of the code samples;
Dashboard.aspx:

Hello,

Edtior adds 3  br in chrome (doesn't happen on IE).

I am doing the following scenario:

<table id="tbl" border="1">        
            <tr><td></td><td></td></tr>
            <tr><td></td><td></td></tr>
            <tr><td></td><td></td></tr>      
</table>


 <div id="editorTextFile">
        <telerik:RadEditor ID="RadEditor1" runat="server" width="100%" Height="100%" ></telerik:RadEditor>
 </div>
<script type="text/javascript">
         $telerik.$(function () {
             $telerik.$("#tbl tr td").click(function () {
                 var editor = $find("<%=RadEditor1.ClientID%>");
                 var content = $(this).html(); //copy cell info
                 $(this).html(""); //clear cell
                 editor.set_html(content); //copy cell info
                 $telerik.$(this).append($telerik.$("#editorTextFile"));
                 $find("<%= RadEditor1.ClientID %>").onParentNodeChanged();
             });
         });

</script>

After clicking on one of the cells in the table, 3 br were added to the editor.

I am working on telerik version: 2013.2.717.40.

*I checked the same scenario on old telerik version: 2010.1.415.20 and it worked fine.

Thanks,
