Hello,

So I need to put information on a grid that has the following structure:

SampleNumber(varchar20)
Date(DateTime)
Notes(text)
IsValid(bit)

the last column (IsValid) does not need to be visible, but if it is set to false, then that particular row needs to be selected. No checkbox or command buttons are needed, the row will be selected only if IsValid == false, hence, everything has to be server side.

Any hint will be appreciated, thanks!

Hello,

i'm trying to select items from a check box on a radgrid but the RadGrid1_ItemCommand does't work...

this is my codebehind
namespace Website

    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)

                RadGrid1.DataSource = getDataSource();
                RadGrid1.DataBind();
            }
        }


        private DataTable getDataSource()
        {
            var dt = new DataTable();
            dt.Columns.Add("IDLOTE");
            dt.Columns.Add("DESC");


            for (int i = 1; i <= 20; i++)
            {
                DataRow dr = dt.NewRow();
                dr["IDLOTE"] = i;
                dr["DESC"] = "desc" + i;
                dt.Rows.Add(dr);

                Int16 stackIndex;
                for (stackIndex = 0; stackIndex <= selectedItems.Count - 1; stackIndex++)
                {

                                break;
                            }

            }
        }
        protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            RadGrid1.DataSource = getDataSource();

what can be wrong?

Dear Team,

I want to achieve the below.

I have a parent page which displays the details about a project. From this, on a button click , I open a radwindow which displays some specific details about the project which displayed in the parent window. The radpopup window has some textboxes and other controls with values along with a UPDATE button.

What I need is, if I change values in the popup and try to close the radwindow without update, it should ask me a confirmation that” Are you sure to close this window without updating your data? The changes will be lost!! Click on CANCEL to return to the window and update". If i try to close the popup radwindow after updated [ie,if I not changed any values after updated] or without any change, it should not ask the confirmation before close the radpopupwindow.

Please help me to achieve this.

Hi,

I am trying to use the logic described in this article (http://www.telerik.com/help/aspnet/grid/radgrid-telerik.webcontrols.gridclientevents-onrequeststart.html) in my RadGrid.  I have it set up as follows:


But I am getting the following error:

Validation (ASP.NET): Attribute 'OnRequestStart' is not a valid attribute of elements 'ClientEvents'.

And when I run the code, I get the following error:

Type 'Telerik.Web.UI.GridClientEvents' does not have a public property named 'OnRequestStart'.

Am I missing something?

Thanks,
Jerry

I am currently using the RadFileExplorer in conjunction with a CustomFileSystemProvider (Hooked to a network share, base on a demo I found here). And while I can upload and download files just fine, it appears that creating folders, renaming items, and deleting items all fail. Deleting told me the application did not have sufficient permissions. What permissions are required? I tried setting the folder up for access to Everyone with Full Control, but that did not seem to help. I even attempted to setup the web to run as the local machines Administrator, but still no luck. Any ideas?

Hi All

Could somone give me som guidance on how best to achive this please.

Many Thanks

Hi All,

I am attempting to achieve the following functionality: I would like to change the background color of the control the user's mouse is currently over when the user is dragging an item.

Reasoning: I allow the user to drag-and-drop items from a RadListBox onto the page. This drag-and-drop functionality creates RadDocks. Once a RadDock is on the page it set's its RadDockZone is forbidden to all other docks. As such, if I had two docks on the page, I indicate that a 3rd RadDockZone is a viable move option by changing that DockZone's background color to green. I would like this functionality to extend to when the user is first creating their RadDock -- I would like DockZone currently being hovered-over to turn green.

Is this possible? I'm looking through the OnClientDragging event, and I can see that it can return (X,Y) coordinates through use of the get_domevent() method. Is there a way to translate this hit coordinate into the control located at the coordinate? 

Thanks for your time,

Sean Anderson

Hi,
in my scenario i've used AjaxManager inside Master page and AjaxManagerProxy inside the content page. I would to know the best approch to ajaxify the radlistview (sorting, paging) inside the content page considering that in  the master page there is radbutton that update radlistview.

Hi All,

  I am adding comments to the database by opening the modal pop up extender. User can type the comment in the modal pop up text box and as soon as the user clicks Ok button, the comments go to the database, and i pull those saved comments from database and display them in the grid.
Everything works fine except when I put the ajax panel around the Ok button, the display of the saved comments stopped right away. I am not sure what am I doing wrong. Below is my code


and the code behind is

radGrid_cComments_Bind , refreshes the gris and shows the user comments right away.

Any help will be appreciated.

You know how you decorate the control with the NoBorders class...?

Can you also decorate it with a Scrollable class if the control has scrolling enabled?

For my .skin file I would like to always have NoBorders, however IF it's in scrolling mode, I'd like a bottom border.  But with the rendered CSS I don't seem to be able to do that.

Again, just to clarify....this is a feature request as you cannot use custom code to define a .skin file :)  So I don't need a sample, I'd just like to know in the CSS when this option is toggled.
