Problems to access items on edit template

Hi, I need to access the components in the edit template of my grid in the Javascript. I saw the code below in a example in the forum, but it's not working for me. My Code:

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated
        If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
            Dim script As String

            Session("inEdit") = True
            rdcbTipo1 = CType(CType(e.Item, GridEditableItem).FindControl("rdcbTipoFonte1"), RadComboBox)
            rdcbTipo1.AutoPostBack = True
            script = "client_rdcbTipo1=" & rdcbTipo1.ClientID & ";\n"
            Page.ClientScript.RegisterStartupScript(Me.GetType, "clientID", script)

            >>>> I tried also : RadAjaxManager1.ResponseScripts.Add(script)
        End If
End Sub

I'm using a master page, where I put >>> var client_rdcbTipo1;

In the javascript the client_rdcbTipo1 is undefined. Is there any problem with my code? How I could access the components of my edit template?

Thanks in advance,

Tooltip with a tooltip

Some of my tooltips have tool tips which make the original tooltip dissappear. How do I keep the original tooltip visible while the second tooltip is up?

Thanks.

[Solved] Custom RadChart MinorTickCount value

Hi,

I'm just wondering if we can set the MinorTickCount to a value other than None, One, Three, and Eight? Most intervals between major ticks are a multiple of 5, 10, 20, 100, 1000 and so on giving a much reasonable value of 5 for the minor tick count.

Is this a limitation of the RadChart control? Why having only an interval of 1, 3 and 8?

Thanks,

Ely

RowIndex ASP.NET code

What is the equivalent of the following code which does exactly what i want with the standard GridView?

    
            <div runat="server" ID='<%# String.Concat("div", CType(Container, GridViewRow).RowIndex %>'> 
        
            ' content here 
        
            </div>

However it's a bit confusing when you work with the RadGrid.

Thanks in advance

grid hierarchy problem

I have a grid with a master and detail table. The master table has several rows. When I click a row to expand the detail table, in the ItemDataBound Event I have some code that populates a dropdown in the detail table, as below

    
            if ("ArtistCategories".Equals(e.Item.OwnerTableView.Name))  
        
                        {  
        
                            if (e.Item is GridEditableItem && e.Item.IsInEditMode)  
        
                            {  
        
                                GridDataItem dataitem = e.Item.OwnerTableView.ParentItem;  
        
                                Hashtable values = new Hashtable();  
        
                                dataitem.ExtractValues(values);  
        
                                object Objgenre = values["Genre"];    
        
                                GridEditableItem _item = (GridEditableItem)e.Item;  
        
                                Telerik.Web.UI.RadComboBox cb = (Telerik.Web.UI.RadComboBox)_item["ArtistCategory"].FindControl("RadComboBoxCategories");  
        
                                string genre = Objgenre.ToString();  
        
                                cb.DataSource = lookupmanager.CategoryByGenre(genre, this.RadComboBoxType.SelectedValue);  
        
                                cb.DataTextField = "Category";  
        
                                cb.DataValueField = "Category";  
        
                                cb.DataBind();  
        
                                try  
        
                                {  
        
                                    Studio1DBObjects.SecondaryCategory sg = (Studio1DBObjects.SecondaryCategory)e.Item.DataItem;  
        
                                    string category = sg.Category;  
        
                                    int index = cb.FindItemIndexByValue(category);  
        
                                    cb.SelectedIndex = index;  
        
                                }  
        
                                catch (Exception ex)  
        
                                {  
        
                                    //  
        
                                }  
        
                            }  
        
                        }

The contents of the drop down are determined by 2 values, a 'type' which is a drop down on the main page, and 'genre' which is a column in the master table in the grid. After searching the forums, the only method I could find to obtain this value from the master table is by using a hashtable, like so

Hashtable values = new Hashtable();

dataitem.ExtractValues(values);

object Objgenre = values["Genre"];

After stepping through the code, the hash table is always empty (its count is zero), yet the master table has data. How Can I obtain the data I need from the selected row in the master table ?? Is there another way ?

drag & drop without removing source node

Hi This may be a very stupid question but can you please help me with this? I am using simple drag & drop between two treeview controls example, however I don't want to remove the source node. I have tried removing this line "sourceNode.Owner.Nodes.Remove(sourceNode)" from the code but it still seems to remove the source node when some one drag it to the second treeview.
Can some one please help?

Thanks

[Solved] TreeView in Grid Form Template Questions

I have a grid that when in edit and insert mode uses a FromTemplate. In that template I want to have a tree view that has checkboxes. The items will load from a SQL data source, but how do I take a column when in edit mode and check the appropriate boxes based on an array item.

My database column is named "banned_sources" and will have a value like so:

Either "0" for no banned sources, or a string like "5,61,64,91,137,139,161"

The numbers in the array match the "source_id" of my datasource. How do select the matches in my tree view if they are present in the array?

ASPX code:

    
            <td> 
        
                        Banned Lead Sources:</td> 
        
                    <td> 
        
                        <asp:SqlDataSource ID="sqlds_affiliates" runat="server"  
        
                            ConnectionString="<%$ ConnectionStrings:Master_ConnectionString %>"  
        
                            SelectCommand="SELECT [source_id], (CAST([source_id] AS VarChar) + '  ' + [affiliate_name]) AS AffiliateName FROM [lead_affiliates] ORDER BY [source_id]"> 
        
                        </asp:SqlDataSource> 
        
            <telerik:RadTreeView ID="tree_banned_sources" Runat="server"  
        
                            AppendDataBoundItems="True" CheckBoxes="True"  
        
                            DataSourceID="sqlds_affiliates" DataTextField="AffiliateName"  
        
                            DataValueField="source_id" MultipleSelect="True"> 
        
                            <CollapseAnimation Duration="100" Type="OutQuint" /> 
        
                            <ExpandAnimation Duration="100" /> 
        
                        </telerik:RadTreeView> 
        
                    </td>

Stupid question

I've got a grid with 5 columns.

First column has a document type name in it.

The last column has a button to allow you to update the version of the file on the server.

I've tried a handful of different things to be able to get the button clicked and actually get the value of the document type column for the row the button is clicked on.

(I am not pasting code for a specific reason right now. Just too many internal pieces of information for my client and they'd be frustrated if I posted details of their project. Also, I've not finished with my workaround yet, so I figure best to just ask the simple question and then correct the code when it's done.)

What I'm currently in the process of doing:

Creating an ImageButton imbedded in a gridtemplatecolumn.
Set the DataValue of the gridtemplatecolumn to the name object from the table.
Set the AlternateText value to the Imagebutton to eval from the datavalue.
On the fire event, parse the AlternateText value to get the argument to send to the file upload page with the document type.

Any ideas as to whether that will actually work?
I know it's a cheat, but how do I do it without kludging it.

I'm down to just a few minor features and a few bug fixes to get this out the door.

Thanks.

Paul
