We would like to use the RadFileExplorer in a classic asp.net web application and connect it to a Sharepoint server and its libraries.

Is this possible with the ASP.NET RAD controls? If so, is there a page somewhere to see an example (from what I understand from the MOSS pages this should be just a couple of lines, right?).

Thank you

Expanded Image URL Not Showing Up

I expand a node with the expandMode = TreeNodeExpandMode.WebService and it expands just fine, but the expandedImageURL doesn't change.

If I build out the tree as to not need the webserice, the expandedimageurl works properly. Am I doing something wrong or is this a bug?

RadTreeNode childNode = new RadTreeNode();

childNode.Text ="TITLE";

childNode.ImageUrl = "/images/theme1/closedfolder.gif";

childNode.ExpandedImageUrl = "/images/theme1/openfolder.gif";

childNode.ExpandMode = TreeNodeExpandMode.WebService;

Column Headers Disappear and Grouping throwing Exception

I am looking into Telerik Grid so I can move from the Infragistics as it has a stranglehold on the application I am working with. Because of that I am preparing the base set of things/standards that our application was following when using IG to work with RadGrid.

In the IG, I have been using a xml file to generate the columns. So for a simple purpose I have duplicated the base xml to match the Telerik xml. One great thing I noticed is everything I wanted to do is built into the grid and I don't have to do any heavy work when working with the HyperLink Column or Image Column.

Problems I am facing:

In our scenario we bind around 250 to 500 records (about 30 columns) and little more depending on the location and most of the grids require grouping. As I mentioned all columns are rendered during page load and the data is bound the grid right after that. Once the data is bound grid looks and behaves normally.

1) Once I perform sort, all the column headers (text) disappears and I see only empty header cells. It also changes the whole grid's shape as the columns had specific size the once rendered after sorting the columns widths are shrunk extensively to match the data.

2) The second problem I am facing is grouping. When I drag columns for grouping, it throws me an object reference error.

3) Auto Scrolling - overflow feature is not working propertly when used with W:100%/ H:100%. It crushes the height into just 3px. I am not sure if this has something to do with the DocType?

I some how feel I have to re-init the columns as the data still exists for setting the datafields. If this is so, what exact events I need to use.

Any guidance now and near future is greatly appreciated.

[Solved] RadWindow Scroll

Hello Telerik Team,

I am just enquiring into how to make a radwindow move as the scroll bar is used on the page behind?

Such that if the user scrolls down the main page the rad window will follow down. I am sure the old Rad Windows did this, but i cannot find an example in the new Rad Ajax Controls for Rad Window.

Thanks in advance

How to add a custom column at runtime?

Hello, I have a grid that is created dynamically at runtime. It is also databound.

Well, we need to be able to add a column to the grid which is filled with hyperlinks that are dynamically generated according to the RowIndex. How would we do this? I just can't figure out how access the Columns in the ItemDataBound and I can't figure out what is the proper way of adding a column that is not in the bound dataset.

Need to programatically set width of column - help please

Because I don't know how many columns will be needed at design time, I've delved into programatically creating grid columns and adding them to the grid. However, I cannot seem to affect the width of the column. Could someone please help me understand how to set the width of the column? If I were doing this in the markup I'd set the HeaderStyle and/or ItemStyle but those appear to be readonly properties when I view them in the codebehind. Help?

Grouping on Code Behind Issues

Hello,

I've been trying to work my head around why i receive the following error:

Exception Details: Telerik.Web.UI.GridGroupByException: Field Location not found in the source table. Please check the expression syntax.

In my code the grid is dynamically bound to an XML datasource, so the column names are not constant and change from report to report, but in my current report the "Location" column is supposed to be grouped so that the group footer will display the sum of another column.

The grid is loaded with data on the NeedDataSource function, where a data table is converted to a dataview and sorted.
After the datasource has been set an event lister is added to the grid to listen for ColumnCreated.
In the ColumnCreated function it listens for the creation of the column that needs to be summed, add the neccessary infomation for the row to sum.
Right after adding the sum information the following code block is used to add the grouping:

    
            GridGroupByExpression ge = new GridGroupByExpression();  
        
            GridGroupByField gf = new GridGroupByField();  
        
            gf.FieldName = "Location";  
        
            ge.SelectFields.Add(gf);  
        
            this.RadGrid1.MasterTableView.GroupByExpressions.Add(ge);

Which leads to the folowing error:

[GridGroupByException: Field Location not found in the source table. Please check the expression syntax.]

I know the Location column is present in the data, and I can use the drag up to group feature when the code segment is removed, but I really need it to just do it by itself.
