[Solved] how to hook up grid to webservice

Hi there,

I've wired up my radgrid to run off a webservice in the code behind file.
But when I create a webservice and place it into a different location then my radgrid doesn't populate. I'm obviously not connecting it properly.

Here is my ASPX:

    
                        <ClientSettings> 
        
                            <DataBinding Location="Default.aspx" SelectCountMethod="GetProductCount" SelectMethod="GetProducts"> 
        
                            </DataBinding> 
        
                            <Selecting AllowRowSelect="True" /> 
        
                        </ClientSettings>

That works but if I change Location="Default.aspx" to Location="Products.asmx" then my grid doesn't populate.

Here is my Products.asmx:

    
            [WebService(Namespace = "Products")] 
        
            [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
        
            // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.  
        
            [System.Web.Script.Services.ScriptService] 
        
            public class Products : System.Web.Services.WebService { 
        
                [WebMethod] 
        
                public static IEnumerable GetProducts(int startRowIndex, int maximumRows) 
        
                { 
        
                    var northwind = new NorthwindDataContext(); 
        
                    var products = from p in northwind.Products 
        
                                   select new 
        
                                   { 
        
                                       ProductID = p.ProductID, 
        
                                       Name = p.ProductName, 
        
                                       CategoryName = p.Category.CategoryName, 
        
                                       Price = p.UnitPrice, 
        
                                       UnitsInStock = p.UnitsInStock 
        
                                   }; 
        
                    return products.Skip(startRowIndex).Take(maximumRows); 
        
                } 
        
                [WebMethod] 
        
                public static int GetProductCount() 
        
                { 
        
                    var northwind = new NorthwindDataContext(); 
        
                    var count = northwind.Products.Count(); 
        
                    return count; 
        
                } 
        
            }

Thanks in advance for taking the time to help me out.

RadGrid Edit/Insert

Hi telerik,

Hopefully this one is easy...

I have a rad grid with following columns: Supplier, ProductName, Product Description. These columns constitute an entity called line item.
On edit/insert I am using inline mode. Now, when in edit/insert mode users are able to search for supplier by supplier name or for a product by product name (I have a search icon next to each entry fields in edit/insert mode which will open a pop-up). Once, values are selected for these fields I also need to store IDs for them behind the scene (for Supplier and for Product),
so for example my OnInsertCommand would look like this:

   protected void RadGrid1_OnInsertCommand(object source, GridCommandEventArgs e)
    {
        GridEditableItem item = null;
        string supplierID = String.Empty;
        string productID = string.Empty;

        item = this.RadGrid1.MasterTableView.GetInsertItem();

       // Get supplier ID for and assign to supplierID variable
          .................
      // Get product ID and assign to productID variable

        //Create new LIne Item
        LineItem llineItem = new LineItem();
        llineItem.GenerateALineItem(supplierID, productID, this.CurrentOrder.OrderID);
        this.CurrentOrder.Order.LineItem.Add(llineItem.GetItem());
        RadGrid1.MasterTableView.Rebind();
    }

How and where can I store these supplierID, productID for edited/new records to retrieve them in these methods (OnInsertCommand
OnItemUpdated)

We have been using telerik for some times now, we've been making this site using telerik. The site was OK until an error showed up.

Line: 6
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'Telerik.Web.UI 2009.'.

We have been using telerik but this is the first time we encountered this error.

Can anybody teach us how to solve this error

RadTreeNode attribute changes not persisted to server

On the client, I'm perfoming the following treenode attribute update:

                                function onNodeClicking(sender, args) {         
                            var treeNode = args.get_node();         
                            var attribs = treeNode.get_attributes();         
                            attribs.setAttribute("test", "54321");         
                                 
                            attribs2 = treeNode.get_attributes();         
                            alert(attribs2.getAttribute("test"));         
                        }         

After the PostBack, the treenode's "test" attribute hasn't been updated and the original is rendered in the TextBox.

                                protected void Page_Load(object sender, EventArgs e)          
                            {          
                                if (!IsPostBack) {          
                                  
                                    RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node1"));                      
                                    RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node2"));                      
                                    RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node3"));          
                                              
                                    RadTreeView1.Nodes[0].Attributes.Add("test", "1234");          
                                    RadTreeView1.Nodes[1].Attributes.Add("test", "1234");          
                                    RadTreeView1.Nodes[2].Attributes.Add("test", "1234");          
                                }          
                            }          
                            protected void RadTreeView1_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e) {          
                                TextBox1.Text = e.Node.Attributes["test"];          
                            }          

I would assume this is a fairly common task and I'm just overlooking something.

Any help is appreciated!

RadGrid GridButtonColumn throws an exception in Firefox 3.0.6

Hi,

I have a RadGrid inside an <asp:panel> in my page.
The grid has a GridButtonColumn that does some AJAX operation in the displayed page. here is definition in the grid:

<

radG:RadGrid ID="grdFavorites" runat="server" CssClass="RadGrid"

AllowPaging="True"

AllowSorting="True"

EnableAJAX="false" EnableAJAXLoadingTemplate="false"

AutoGenerateColumns="False"

Skin="None"

LoadingTemplateTransparency="7"

PageSize="100" Width="100%" GridLines="None"

OnItemCommand="grdFavorites_ItemCommand"

OnItemDataBound="grdFavorites_ItemDataBound" onfocus="this.blur();"

AllowMultiRowEdit="true"

OnNeedDataSource="grdFavorites_NeedDataSource">

</ClientSettings>

<MasterTableView

HeaderStyle-CssClass="RadGridHeader"

FooterStyle-CssClass="RadGridHeader"

ItemStyle-CssClass="RadGridItem"

AlternatingItemStyle-CssClass="RadGridAltItem"

Width="100%"

GridLines="none" DataKeyNames="Id" Style="cursor:pointer;"

AllowMultiColumnSorting="True"

BorderWidth="0">

.......
<radG:GridButtonColumn ItemStyle-Width="7%" ButtonType="ImageButton" ImageUrl="../Images/MyImage.gif"

HeaderText="Remove"

UniqueName="RemoveFavorites" CommandName="RemoveFromFavorites"

Reorderable="False" Resizable="False">

</radG:GridButtonColumn>

</

Columns>

This works ok on IE (tested versions 6-7). However, in Firefox I get an error, It seems the error is on the imagebutton (see the below NET error).

Can anyone help out on this one? Is this a known issue? I can debug the code, but I think it is useless...

Thank you!

RadSpell - Runtime find - spell error still exists ?

Hi,
I have a small query regarding the telerik:RadSpell.

Is there any property exposed so that a developer can determine "Is any spell errors still exist" at runtime.

For example : Lets have this scenario.

User enters some text in a textbox
User click spell check button. spell check functionality is invoked.
Now user may change some errors or ignore (as he/she may like).
Now how a developer will know "Is there stil any error after runing the spell check".

please do the needful

Thanks,
Sushil

Can I set the Telerik WebResource to debug?

Hi,

We are currently developing an application that is using a ginormous amount of Telerik controls (a majority of which have been extended in some regard). Every once in a while, we come across an error that is being churned up by MS Ajax and would like to figure out what exactly was going on with it. It's a real pain because the Telerik DLL is using the release version of MS Ajax. Has anyone in their travels come across a way to have Telerik use the debug version instead? Is this because Telerik.Web.UI.dll was compiled using the release version? Are there any workarounds?

Thanks.

[Solved] LoadOnDemand tooltip size?

Hi,

I am loading a usercontrol into a tooltip as per the example on your site. This all works fine techincally, however, it seems that the tooltip can only be of ONE set size height + width.

So for example, I have 2 linkbuttons at the top of the page. One link button opens a tooltip and displays a small list of radiobuttons. The other linkbutton however needs to display a treeview - therefore we have 2 very different sizes here.

As per the example, I have using tooltipmanager and the targetControls collection - it seems that instead of being able to specify different sizes for different target controls in the collection, I can only specify width and height properties for the tooltip manager itself - and this sucks when he have more than one tooltip/different size tooltips on the page.

Is there any workaround for this? Maybe a way to set height and width dynamically onajaxupdate?

As a feature it would definately be better to be able to specify tooltip height and width for each targetcontrolid.

Thanks,
Matt
