Hi,

I would like to save the filter expressions and the sort expressions of my detail tables in my RadGrid so I could reload them when I come back to the page.

I use SqlDataSource and this :
http://www.telerik.com/help/aspnet/grid/grdsavingsettingsonperuserbasis.html

It's working for my MasterTableView but when I'm looking for my detailTables :
gridInstance.MasterTableView.DetailTables(0).FilterExpression it has no value (but the filtering of the detailTables is working)

I would like to know where the can I get the filter expression of my DetailTables so I can save it.

Thanks
Francis

[Solved] LoadOnDemand and Expand All

Hello all,

I've looked through the site a bit and found some info, but nothing that was exactly my problem, so here goes.

I have two treeviews TreeViewStart and TreeViewEnd. TreeViewStart is used kind of like a source for children. I have built this to be Load On Demand, and that part works wonderfully. I have also built it so that I can drag and drop a node and all its children to TreeViewEnd. That also works fine.

My problem, is that after the user has selected how the treeview should be (TreeViewEnd) using nodes from TreeViewStart, I needed to get the xml of that tree. So when the user clicks a button at the bottom I run the .GetXml function and get back my string. The problem with this is that I only get back information on the already expanded nodes. I believe this problem to be due to the load on demand and the non-existance of child nodes. The .ExpandAll() doesnt seem to work for me probably for the same reason.

Is there a way to make it so that when the user clicks the "Complete" button, that it will Expand all nodes on TreeViewEnd so that the .GetXml return string is accurate without forcing the user to click through all the child nodes? Below are some snippets of code.

Thanks in advance.

Dynamic Template creation for custom control

I am having problems creating a ItemTemplate for a user control.

The following code is what I have roughed out and can't get it to work. I am trying to create an anchor based on the the dataTable I have bound to the the RadRotator.

Here is my template code
Thanks in advance.

public class RotatorTemplate : ITemplate

{

private Control _container;

public void InstantiateIn(Control container)

{

_container = container;

Literal contents =

new Literal();

contents.DataBinding +=

new EventHandler(contents_DataBinding);

container.Controls.Add(contents);

}

private void contents_DataBinding(object sender, EventArgs e)

{

Literal contents = sender

as Literal;

contents.Text =

"<a href="<%# originalAttribute="href" originalPath=""<%#" originalAttribute="href" originalPath=""<%#" DataBinder.Eval(contents.BindingContainer, &quotDataItem.LinkUrl")%>" target="_blank"> <img src=&quotIMG/<%# originalAttribute="src" originalPath="&quotIMG/<%#" originalAttribute="src" originalPath="&quotIMG/<%#" DataBinder.Eval(contents.BindingContainer, "DataItem.ImageUrl") %>" alt="" style="border:0px;&quot/></a>";

}

How to Set ExpandedSize

Hi,

I'm following your example on how to keep the persistant state of the radsplitter across pages and postbacks from here
http://demos.telerik.com/aspnet/prometheus/Splitter/Examples/SaveLoadStateOnServer/DefaultCS.aspx

The problem is your samples shows you can set the expanded size in the example with the method SetSettings(), BUT THE
SetExpandedSize is not a method in the RadPane class, I get a compile error when I do it saying that. I am using RadControls 2008.2.723.20. The persistant works perfect except the expanded size. How can I set this if it isn't part of the class?

public void SetSettings(RadPane pane)
            {
                pane.Width = this.Width;
                pane.Height = this.Height;
                pane.SetExpandedSize(this.ExpandedSize);
                pane.MinWidth = this.MinWidth;
                pane.MinHeight = this.MinHeight;
                pane.MaxWidth = this.MaxWidth;
                pane.MaxHeight = this.MaxHeight;
                pane.Collapsed = this.Collapsed;
                pane.Locked = this.Locked;
                pane.ContentUrl = this.ContentUrl;
            }

Reoder Nodes and Update Database & Disable Drag Drop per node?

First, i have been looking a the examples on drag and drop and see how I can reorder the nodes. In my database I have an ORDER field that determines the order of records when displayed. How can I keep track of which nodes have been reorder so I can update my database?

Second, I have been trying to figure out how to disable dragging / dropping per node. Here is my structure:

Project
     Photo Set 1 (Disable Drag and drop and reorder)
          Photo 1 (Image with Thumbnail)
          Photo 2 (Image with Thumbnail)
     Photo Set 2 (Only Allow reordering of child nodes)
           Photo 3
           Photo 4

HEre is the treeview object on the ASPX page:

<

telerik:RadTreeView ID="rtvProjects" runat="server" EnableDragAndDropBetweenNodes="true" EnableDragAndDrop="true" OnNodeDrop="RadTreeView1_NodeDrop">

</telerik:RadTreeView>

I am creating the nodes problematically in the VB code behind. I tried setting the AllowDrop/AllowDrag per node, but it still lets be drag and drop between nodes and into the nodes.

I can give you all my code, if you need, but let me know if this makes sense.

GridDateTimeColumn Issues

I have successfully added the datepicker drop down as a filter for the grid. This is much better that typing in a date but I have some issues !

<telerik:GridDateTimeColumn DataFormatString="{0:d}" DataField="Date" HeaderText="Date" ReadOnly="True" SortExpression="Date" UniqueName="Date" DataType="System.DateTime" ></telerik:GridDateTimeColumn>

1. the BETWEEN filter is removed. How can I get 2 datepickers to drop down to get a between filter ?

2. I can not fully format the datepicker ! In codebehind I have added in

RadGrid1_ItemCreated

event the following:

Dim datebox As RadDatePicker = CType(filteringItem("Date").Controls(0), RadDatePicker)

datebox.Width = Unit.Pixel(80)
datebox.Skin = Application(

"TelerikTheme")
datebox.Calendar.ShowColumnHeaders = False
datebox.Calendar.ShowRowHeaders = False
datebox.Calendar.ShowOtherMonthsDays = False
datebox.Calendar.FastNavigationStep = 12

These 1st 2 above items in green work the size shrinks and a user's skin choice is applied , However the other 4 items compile, but have no affect on the look of the grid !

How can I modify the elements of the datepicker filter ?

Thank You !
