[Solved] Add Radcombobox as filtering Item in radgrid Progammatically

Hi Forum,
Please assist, I am creating the Radgrid programmatically and want to add Radcombox as a filtering item to it.
No Clue, and I've tried everything I can find.
I want the design output like the attached file.

Bali.

here is the code i am using

     rdGrd = new RadGrid();
            rdGrd.AutoGenerateColumns = false;
            rdGrd.AllowPaging = true;
            rdGrd.AllowSorting = true;
            rdGrd.AllowFilteringByColumn = true;

            rdGrd.Width = Unit.Pixel(600);
            rdGrd.EnableAJAX = true;
            rdGrd.EnableAJAXLoadingTemplate = true;
            rdGrd.Skin = "None";

            rdGrd.NeedDataSource += new GridNeedDataSourceEventHandler(rdGrd_NeedDataSource);
            rdGrd.ItemDataBound += new GridItemEventHandler(rdGrd_ItemDataBound);
            rdGrd.PageSize = 25;
            rdGrd.ID = "grd";

  GridBoundColumn boundColumn1 = new GridBoundColumn();
                boundColumn1.DataField = "FirmName";
                boundColumn1.UniqueName = "Firm";
                boundColumn1.HeaderText = "Firm";

[Solved] Aggregate function name is not displayed for Columns having custom format applied

Hi,

I have a radgrid with dynamic GridBoundColumns created, where we apply custom format string to each of them based on data type
eg: boundColumn.DataFormatString = "{0:N}" for decimal or any number type.

I have support for both server-side and client-side aggregate functionality. But facing some issues now.

Scenario : If we apply a custom DataFormatString to a column
Grid is loaded fine. But if user selects a aggregate type using Footer Aggregate Menu from Column Header, Aggregate Name is not displayed within the footer result.

Aggregate Operation is executed fine and desired result is displayed but we are not able to see the Aggregate name.

Eg: We apply “Count” aggregation on Column1 then the footer result is displayed as “x.
The expected result should be “Count : x”

It works fine when no dataformat string is applied on bound columns.

Here is a post which says , which in-turn says aggregate title names can be turned off by seting DataFormatString.
http://stackoverflow.com/questions/1244894/telerik-radgrid-custom-aggregate-unwanted-text

So in our case, its the same that is happening. We are setting the dataformatstring and cant see the aggregate titles.

Need a solution to get this working. Are there any specific constraints to use in order to support both server side and client side aggregates with formats applied ? Or am I missing anything here ?

Any thoughts ?

RadDatePicker: how to prevent postback on validation error?

Hello,

In the RadDatePicker control I've set MaxDate/MinDate and ValidationGroup, but I am still able to submit form with invalid date.

Using following example I am able to submit form with "AA" text or "1/1/2020" date in the RadDatePicker. I've tried solution with raddatepicker validation but it doesn't work when user presses Enter - form is submitted.

Please check my example.

tri state doesn't work properly

Posted 0 minutes ago (permalink)

1. i have tree with about 4 levels
the first level i get from server code and the other
by webservice.

in the begining i just recieve
the first level
i know from advanced what is their checked property
some are:

0 - Unchecked

1 - Checked

2 - Indeterminate

how can i set these values by code ,when the component can't make it itself
, because it doesn't have childs yet (until i click on some of the first level and recive by webservice their childs. the second level)

2. one more problem is that tri state doesn't work properly. example: one of the three childs isn't checked, the father of it, the second level is Indeterminate but the first level is Checked instead of Indeterminate

SharePoint 2010 'Telerik.Web.UI' could not be loaded.

Hi -

I have:
Installed AJAX
Installed RadControls_for_ASP.NET_AJAX_2010_1_519_dev.msi
Added a RadGrid to a web part
Complied and deployed using VS 2010

On runtime I get:

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

One issue may be that I do not see two required dll's in the GAC.

Telerik.Ajax.SharePoint.dll and RadEditorSharePoint.dll.

I do not see these anywhere in the Rad install path or on my hard drive either.

Please advise where these are located.

I noticed when I ran the Telerik installer it did not update the GAC or sp web.config either.

Thank you.

display radgrid in new radwindow on same page and enable drag and drop from that radgrid to another radgrid on same page

I am developing prototype using telerik rad controls. One of my requirement is to display a radgrid dynamically inside a radwindow which comes up as a new pop window, on hyperlink click event. There is an additional radgrid on the page. I would then want to drag a row from the dynamically created radgrid(inside radwindow) into existing radgrid on the same page.
I know that radwindow can be used as container for containing controls from same page but I want to the radwindow as new pop up on same page and then I can refer Id's of both radgrid controls while drag and drop.

Kindly reply

TreeViewNode.ContextMenu in codebehind?

Hi all,

Apologies if this is a question answered elsewhere or if I've missed something simple.

I've got a treeview in which I build the nodes dynamically based on a datasource - specifically I'm manually creating new RadTreeNodes and inserting them because I want different behaviours based on each, but that's probably not directly relevant. At the time of creating each node I assign it to a predefined (in the .aspx) RadContextMenu, like this:

    
            RadTreeNode contactNode = new RadTreeNode();  
        
            if (contact == currentCustomer.ContactAccounts)  
        
               contactNode.ImageUrl = "~/images/icons/16/user-business.png";  
        
            else 
        
               contactNode.ImageUrl = "~/images/icons/16/user-worker.png";  
        
            contactNode.Text = contact.Name;  
        
            if (contact.Email.Length > 0 && contact.Fax.Length > 0)  
        
            {  
        
               contactNode.ContextMenuID = "contactContextMenuEmailAndFax";  
        
            }  
        
            else if (contact.Email.Length > 0)  
        
            {  
        
               contactNode.ContextMenuID = "contactContextMenuEmailOnly";  
        
            }  
        
            ... etc etc etc

There are two things I'd like to do and haven't found a means of doing:

1) rather than define 4 multiple menus including email, fax, email and fax and neither, it'd be nice to be able to iterate the collection of menuitems and simply disable the ones that don't matter

2) I'd like to set the NavigateUrl property of the "Email contact" menu item to a mailto: link at render time

Is there a way to do this?

Cheers,

Kev

Custom Filter Column and no viewstate problem

Hello,

I am using a Grid with a custom filter column as described in the demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx

The problem I have is that when I turn off the viewstate for the grid the event below does not fire in the event chain.

private void rcBox_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair());

}

private void rcBox_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair());

}

private void rcBox_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair());

}

If I turn on view state then it works fine. I have tried setting the selectedvalue in the "protected override void SetupFilterControls(TableCell cell)" method as follows, but all that does is maintain the selectedvalue during postback and does not cause the rcBox_SelectedIndexChangedevent to fire. You can see from the code below I tried to fire the Filter command but it is too early and causes other problems.

var formvalue = HttpContext.Current.Request.Form[rcBox.UniqueID];

if (!string.IsNullOrEmpty(formvalue))

{

rcBox.SelectedValue = formvalue;

//((GridFilteringItem)(rcBox.Parent.Parent)).FireCommandEvent("Filter", new Pair());

}

Is this a bug in the grid, my only solution is to use viewstate but this is a large gird.

I have also notcied that if the viewstate is switched off you can not change page with the page number buttons and can only use the left and right page buttons.
