jQuery in the Telerik.DLL

I just used a Hex Editor to check which version of jQuery was in the 2011-11-14 Telerik.Web.UI.dll that I'm using (v.2011.2.915.35). It appears to be Version 1.5 of jQuery.

The jQuery website states that the latest version available is 1.7.1.

When do you plan to incorporate this into your DLL?

radMenu showing under radTabStrip when tab strip has horizontal scroll buttons

Hi,

I have a menu and a tab strip on the page, the menu root is above the tab strip and the menu

I'm having a problem with z-indexes for radMenu and radTabStrip when the tab strip goes over the width of the window and shows the buttons to scroll left and right (next and previous arrows). When this happens, the radMenu shows under the Tab Strip and I need it to show above. I tried to play with z-index everywhere but had no luck.

However, when the tab strip do not have those scroll buttons, it works perfect, the menu shows above the tab strip.

Thanks for any help
Eduardo

DynamicRadGrid RadCombox Filter MetaForeignKeyColumn

Ok-

Can anyone give me any insight into how the DynamicRadGrid Column Filters work? Here is the scenario.
I am using DynamicData and the Telerik.Web.UI.DynamicRadGrid.

I have created a custom class that inherits from ITemplate. My Custom Template Class builds a RadComboBox using the MetaForeignKeyColumn passed to it. In the Template Class I have also subscribed to the ComboBox.selectedIndexChanged Event and fire the Filter event passin a new Pair that contains the columnname and value to filter on.

/// <summary>

/// Summary description for ForeignKeyFilterTemplate

/// </summary>

public class DDForeignKeyFilterTemplate : ITemplate

{

private MetaForeignKeyColumn _column;

private RadComboBox _ddlb = new RadComboBox();

private const string NullValueString = "[null]";

private DSIWebDbDataContext _context;

private string _filterColumnName = string.Empty;

public DDForeignKeyFilterTemplate(MetaForeignKeyColumn MetaColumn)

{

_column = MetaColumn;

_ddlb.Skin = "WebBlue";

_ddlb.EnableViewState = true;

_ddlb.AutoPostBack = true;

_ddlb.AllowCustomText = false;

_filterColumnName = _column.ForeignKeyNames[0];

}

#region ITemplate Members

public void InstantiateIn(Control container)

{

_ddlb.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(_ddlb_SelectedIndexChanged);

if (_ddlb.Items.Count <= 0)

{

if (!_column.IsRequired)

_ddlb.Items.Add(new RadComboBoxItem("[Not Set]"));

PopulateListControl();

}

container.Controls.Add(_ddlb);

}

void _ddlb_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair(e.Text, _column.Name));

}

private void PopulateListControl()

{

_context = (DSIWebDbDataContext)_column.Table.CreateContext();

string PrimaryKeyName = _column.ParentTable.PrimaryKeyColumns[0].Name;

string DispalyColumnName = _column.ParentTable.DisplayColumn.Name;;

string ParentTableName = _column.ParentTable.Name;

_ddlb.DataValueField = PrimaryKeyName;

_ddlb.DataTextField = DispalyColumnName;

switch (ParentTableName)

{

case "Bookings":

loadBookings();

break;

case "SiteLocations":

loadSiteLocations();

break;

case "ContainerSizes":

loadContainerSize();

break;

case "Drivers":

loadDrivers();

break;

case "Carriers":

loadCarriers();

break;

case "YardPositions":

loadYardPositions();

break;

case "ContainerTypes":

loadContainerTypes();

break;

}

private void loadBookings()

{

var results = _context.Bookings.Select(b => new idname() { id = b.booking_key.ToString(), name = b.Booking_Number });

results.OrderBy(o => o.name);

if (results.Count() > 0)

{

foreach (var item in results)

{

_ddlb.Items.Add(new RadComboBoxItem(item.name, item.id));

}

private void loadSiteLocations()

{

var results = _context.SiteLocations.Select(b => new idname() { id = b.ref_key.ToString(), name = b.Location });

results.OrderBy(o => o.name);

if (results.Count() > 0)

{

foreach (var item in results)

{

_ddlb.Items.Add(new RadComboBoxItem(item.name, item.id));

}

In the DynamicRadGrid Init Method I am creating a new instance of my Template Class and assigning it to the DynamicGridBoundColumn.FilterTemplate.

DynamicGridBoundColumn gridColumn = new DynamicGridBoundColumn();

string fieldName = string.Empty;

string fieldAlias = string.Empty;

gridColumn.DataField = column.Name;

gridColumn.ConvertEmptyStringToNull = column.ConvertEmptyStringToNull;

gridColumn.DataFormatString = column.DataFormatString;

gridColumn.UIHint = column.UIHint;

gridColumn.HtmlEncode = column.HtmlEncode;

gridColumn.NullDisplayText = column.NullDisplayText;

gridColumn.ApplyFormatInEditMode = column.ApplyFormatInEditMode;

gridColumn.HeaderText = column.DisplayName.Replace("_"," ");

gridColumn.Resizable = true;

fieldAlias = column.DisplayName;

fieldAlias = fieldAlias.Replace("_", "");

//Set up grouping for ForeignKeyColumns

if (column is MetaForeignKeyColumn)

{

fieldName = ((MetaForeignKeyColumn)column).ForeignKeyNames[0];

gridColumn.FilterTemplate = new DDForeignKeyFilterTemplate(((MetaForeignKeyColumn)column));

gridColumn.FilterListOptions = GridFilterListOptions.VaryByDataTypeAllowCustom;

}

else

{

fieldName = column.Name;

fieldAlias = column.DisplayName;

gridColumn.FilterListOptions = GridFilterListOptions.VaryByDataType;

}

// Country [Country], count(Country) Items [Items] Group By Country

gridColumn.GroupByExpression = fieldName + " [" + fieldAlias + "], count(" + fieldName + ") Items [Items] Group By " + fieldName;

MasterTableView.Columns.Add(gridColumn);

This works great and I get the RadComboBox boxes with the appropriate ParentTable values as custom filter dropdowns in each column of the Grid.

The issue:
When i select a new value in the dropdowns, i am getting value not found error on the filter event.
I have tried to overload the DynamicGridBoundColumn both the GetCurrentFilterValueFromControl and the SetCurrentFilterValueToControl.

protected override string GetCurrentFilterValueFromControl(TableCell cell)

{

if (cell.Controls[0] is RadComboBox)

{

string currentValue = ((RadComboBox)cell.Controls[0]).SelectedItem.Text;

this.CurrentFilterFunction = (currentValue != "" && currentValue != "empty ") ? GridKnownFunction.EqualTo : GridKnownFunction.NoFilter;

return currentValue;

}

else

return base.GetCurrentFilterValueFromControl(cell);

}

protected override void SetCurrentFilterValueToControl(TableCell cell)

{

if (cell.Controls[0] is RadComboBox)

{

if (!(this.CurrentFilterValue == ""))

{

((RadComboBox)cell.Controls[0]).Items.FindItemByText(this.CurrentFilterValue).Selected = true;

}

else

base.SetCurrentFilterValueToControl(cell);

}

I have even trapped the event in the Grid_ItemCommand Event setting the FilterExpression on the column and the MasterTableView.

#region Filter Items

if (e.CommandName == RadGrid.FilterCommandName)

{

Pair filterPair = (Pair)e.CommandArgument;

GridFilteringItem item = e.Item as GridFilteringItem;

GridColumn filterColumn = item.OwnerTableView.GetColumn(filterPair.Second.ToString());

filterColumn.CurrentFilterFunction = GridKnownFunction.EqualTo;

filterColumn.CurrentFilterValue = filterPair.First.ToString();

RadGrid1.MasterTableView.FilterExpression = filterColumn.EvaluateFilterExpression(item);

}

#endregion

I'm not sure if there is something i am missing. The underlying column that i am trying to filter is a DynamicControl and is a ForeignKey so the values of the drid are actually the DisplayName of the parent table. At one point i was getting a datatype miss-match as the comparer was trying to filter the EntityName (SiteLocation) to a string, which was the value (key) selected in the dropdown from the parrent table.

Any Ideas or help would be appreciated.
Thanks
Paul
