NoRecordsTemplate Cut Off

I have a RadGrid with a simple NoRecordsTemplate, just an asp:Panel containing an asp:Label. The label text is fairly long. I do not want the text to wrap, so I specified white-space:nowrap in the css class for the panel. The panel displays narrower than the text, and the text is cut off partway (and outside of the panel). If I add a specific width to the panel, it is cut off as well. I have ShowHeadersWhenNoRecord set to true, and it appears as if the no records template is being placed in a table cell the width of the first column, which would explain why it is being cut off. How do I make the no record template span multiple columns so the full width of it will be displayed?

And as a follow up: Can I put in a request that the cell the no records template is placed in be set to colspan ALL of the table columns? Since there is no data to display anyway, and thus no grid, this certainly shouldn't hurt anything, and would give us much more flexibility in the use of the no records template.

TreeList disappears after clicking expand

I have a TreeList that loads onclick of a button (btnGeoDetailsFacilities) which calls RadGeoTreeListFacilities_Bind() this function grabs the parents. All of that works fine, I get parent rows.

Problem:

The problem is when I click the expand node the Treelist and headers disappear and no event is called. If I click the “btnGeoDetailsFacilities” button a second time RadTreeList1_ChildItemsDataBind is called and the grid loads with child items expanded as it should have when I clicked the expand button.

Question:

Why are the Tree and headers disappearing on expand and how do I get it to work properly e.g. show children when I click expand? As show here http://demos.telerik.com/aspnet-ajax/treelist/examples/databinding/loadondemand/defaultvb.aspx

Edit cell capability

While many pivot tables are aggregates, there is plenty of usefullness to have the 3-d format of a pivot and still be able to handle if the user would like to update a cell value in the aggregate section. Is there anyway to do this?

The grid shows empty columns

In the grid whenever text within the tags is saved it is not visible in the data bound columns.

Ex. If this text <Coffee> is bound to the data column then it does not appear in the column , rather a blank space appears.

(This may be probably as while rendering its considering text as a tag as its b/w tags <>)

What can be the potential fix for this issue?

(I guess similar issue persist in this site in demo of grids. Inline Editing of grid columns. [on saving <Tea> as column value value does not save])

Filter from current row values

I have followed this sample:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx

and created a column type to fitler with a radcombobox. I added a DataSourceID to my column and when I set it the whole thing works correctly.

However I would like to add another option to have fitlering based on the items currently in the list. I overrode the PrepareCell method and add the unique items as they go by:

                       public override void PrepareCell(TableCell cell, GridItem item)         
                    {         
                                 
                        base.PrepareCell(cell, item);         
                     
                        if (UseAvailableValuesForDataSource && item is GridDataItem)         
                        {         
                            if (rcBox.Items.FindItemByText(cell.Text) == null)         
                            {         
                                rcBox.Items.Add(new RadComboBoxItem(cell.Text));         
                     
                            }         
                                   
                        }         
                     
                    }         
                     

This fills the combobox with the unique values, however when I get back into the SetCurrentFilterValueToControl & GetCurrentFilterValueFromControl the value of the selected item is empty and so the filter doesn't get set. I tried storing a list in ViewState and restoring from there but that didn't seem to work. (For some reason my ViewState items wouldn't be restored either?)

Is there anyway to filter based on the currently displayed items instead of getting the full set back from the datasource?

Thanks,

Grid
