RAD Grid control - get the selected rows

Hi,

In RAD Grid Q3 2007 version, how to get all selected rows in the radgrid in javascript?

I tried the following code, but it returns only the count of the current DetailTableView only; where the page is a web user control.

                    function OnRowSelected()         
            {         
                var noOfRowsSelected;         
                noOfRowsSelected = this.SelectedRows.length         
            }         

Here is the declaration of the grid control:

<MasterTableView
            
<MasterTableView
            
<MasterTableView
            
                                <rad:RadGrid ID="grdViewRegistries" runat="server" AutoGenerateColumns="False" GridLines="Vertical"         
                            Height="220px" AllowPaging="false" AllowSorting="false" EnableAJAX="true" Skin="BlueCare"         
                            OnItemDataBound="grdViewRegistries_ItemDataBound" HorizontalAlign="Center" AllowMultiRowSelection="true"         
                            AllowMultiRowEdit="true" EnableOutsideScripts="true" EnableAJAXLoadingTemplate="true"         
                            OnDetailTableDataBind="grdViewRegistries_DetailTableDataBind" OnItemCreated="grdViewRegistries_ItemCreated">         
                            <ClientSettings ApplyStylesOnClient="true" AllowExpandCollapse="true" ClientEvents-OnRowCreated="onRowCreated">         
                                <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />         
                                <ClientEvents OnRowMouseOver="ChangeColor" OnRowMouseOut="RemoveColor" OnRowDeselected="RowSelectColor"         
                                    OnRowSelected="RowSelectColor" />         
                                <Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="220px" />         
                            </ClientSettings> 
            <MasterTableView>
            </MasterTableView>
                                                        
            </rad:RadGrid>         

Please let me know.

Thanks

Radgrid grouping event

Hi,

I want to do some custom adjustments when a user uses the grouping function in radgrid. Now my real problem is catching the event that should happen when you use the grouping and I can't seem to get it. From reading I thought that the grid would always use a ItemCommand and that you could simply use:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "RowClick")
        {
               // Do something
        }
    }

And simply change the "RowClick" with what ever the name might be of a grouping so I just put a breakpoint there and tested it but I never stopped there. My grid is called RadGrid1 so that shouldn't be a problem, do I need todo something else to make the grid throw out events?

Also any links to where I can read up more would be great, but I've been trying to read on all the helps and API's I can find and they just don't do it, I can't seem to understand or get it right.

Radgrid as search

I'm trying to use the Radgrid as a search form.

When the grid is first loaded, I want it to bring back zero records, but show the columns and their various filter boxes and the command item section. When a filter is selected, it then brings back the relevant records.

Currently, I am bringing back the full set of records, and then the user filters from there. I only want to bring back the records after a filter has been entered.

Thanks!

RadGrid Paging with GridDropDownColumn

I have a control that has a Radgrid with three GridDropDownColumn as RadComboBox. I have been trying to enable paging for it and it works for all the other fields but this 3 fields. I'am assigning the Datatable that i use as datasource to the Viewstate and use the following code in the PageIndexChanged and NeedDataSource events:

if (ViewState["GridData"] != null)

{

grdCitasMasivas.DataSource = ViewState["GridData"];

grdCitasMasivas.Rebind();

}

What could i do to make the paging work for the GridDropDownColumn columns?

Skin built using style builder doenot render properly in IE

Hi,

I am using style builder to create my own set of skin for each rad controls. These custom skins for all controls including rad scheduler and rad splitter are set at application level in web config file.

Above Rad controls render properly in Firefox and Chrome but my application is a mess in Internet Explorer. How can I make application level custom skins compatible with all browsers?

Before using Custom Skins built using style builder, everything was working fine except for few minor issues. Now, radscheduler and splitter does not implement css rules in Internet Explorer.

Thanks,
Prava

Custom skin on TreeList

Hi,

On the radTreeList set of demo pages there is a skin that appears to be based on the "Default" skin, it has red buttons. It works very well, are there plans to promote this to a full blown skin for all controls?

Also will it be possible in the future for a skin such as default to have some way of tweaking one colour value and have it change it's appearence on all controls.

As an example of what I mean, take for example the Default theme, mainly grey. If we had a session var set to red then all buttons on the theme would be based on a the red, change the session var to green and the buttons change to green.

This would be a tremendous aid for customising our systems for clients, say one client had their main corporate colour as green then simply change the session var to green for them. All relevant highlights on the theme would be green.

Yes we can create our own skins now but there is a major headache with each new release in that we need to test everything.... Having a setting like the one described would enable us to be always upto date.

Best Regards,

Jon
