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

Filtering not working with custom template column

Hi

I have created custom template column for filtering . Given below is code of MyCustomFilteringTemplateColumn.cs. I m using Entity datasource

//RadGrid will cal this method when the value should be set to the filtering input control(s)

protected override void SetCurrentFilterValueToControl(TableCell cell)

{

base.SetCurrentFilterValueToControl(cell);

RadComboBox combo = (RadComboBox)cell.Controls[0];

if ((this.CurrentFilterValue != string.Empty))

{

combo.Text = this.CurrentFilterValue;

}

//RadGrid will cal this method when the filtering value should be extracted from the filtering input control(s)

protected override string GetCurrentFilterValueFromControl(TableCell cell)

{

RadComboBox combo = (RadComboBox)cell.Controls[0];

this.CurrentFilterFunction = (combo.Text.Trim() != "") ? GridKnownFunction.EqualTo : GridKnownFunction.NoFilter;

return combo.Text;

}

private void list_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)

{

Collection<Entities.ProjectUsersAndGroups> collDataSource = (Collection<Entities.ProjectUsersAndGroups>)FilterDataSource;

((RadComboBox)o).DataTextField = this.DataField;

((RadComboBox)o).DataValueField = this.DataField;

((RadComboBox)o).DataSource = collDataSource;

((RadComboBox)o).DataBind();

break;

}

private void list_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

GridFilteringItem filterItem = (GridFilteringItem)((RadComboBox)o).NamingContainer;

if ((this.UniqueName == "Index"))

{

//this is filtering for integer column type

filterItem.FireCommandEvent("Filter", new Pair("EqualTo", this.DataField));

}

//filtering for string column type

if (this.UniqueName == "ProjectCategoryName")

this.UniqueName = "ProjectCategoryDetails.ProjectCategoryName";

filterItem.FireCommandEvent("Filter", new Pair("Contains", this.DataField));

}

While filtering I am getting error "Expression expected " on this line filterItem.FireCommandEvent("Filter", new Pair("Contains", this.DataField));".

Please help me out

Using radalert as server side "MessageBox"

Hi!

I am currently moving from RadControls for ASP.NET to Prometheus. I have a problem with the radalert function. It works fine in RadControls for ASP.NET but not in Prometheus.
I want to generate a "message box" with a message generated on server. I do it by registering a startup script in the script manager.
Using standard windows alert from server as well as radalert from client works fine.
But as soon as I use radalert from server then the radalert is 'undefined'. I guess that the RadWindowManager is 'undefined'.

How can I solve this problem?

Small code sample is attached below.

Thanks
/Mats
