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

Using Right-Click to Effect Left-Click

Please take a look at the enclosed screenshot. Notice that the 3rd item (in blue) in the RadListBox has been previously selected (via a traditional left-click). But then the user chose to go to the 7th item (in yellow) and right click there. Ideally what I'd want to happen, if the user chooses a valid menu item, is for this 7th item to be processed instead of the 3rd. In other words, if the user chooses "Move Muck" in the Context Menu then I'd first want the 7th item in the RadListBox to be selected.

But, search as I might, I could not find out where to detect that the Context Menu was hovered above the 7th item.

How would I resolve this?

Grid Unresponsive When Published

Hello -
I am fairly new to all of this. My RadGrid works as expected when I debug with the VS Debug Server, but when I publish to IIS and browse the page, the grid renders but does not respond to clicks. (No paging, no expanding, no filtering, etc.). It may be something obvious I am missing.

I am also using a masterpage, and I am wondering if the issue lies here? I don't understand why something would work in the VS Debug Server and not on IIS.

Thanks so much,
Kaveh

Edit:
I found this post:
http://www.telerik.com/community/forums/aspnet-ajax/grid/sys-webforms-pagerequestmanagerservererrorexception-error.aspx

Which is the same problem I am having. Using the full URL seems to fix it.

RadGrid + RadAjaxManager + jQuery Validation Plugin issue

I've an editable RadGrid which on edit shows a custom user control as a pop-up. The grid was embedded in an update panel and the user control used jQuery Validation plugin for validating the inputs.

I was facing issues with displaying the wait panel during ajax calls. To resolve this I removed the update panel and implemented RadAjaxManager following which the wait panel is functioning perfectly. But that broke the jQuery Validation plugin functionality. What I understand is that RadAjaxManager handles the ajax requests and doesnt trigger the events that the validation plugin is hooked to.

Is there any way of getting RadGrid + RadAjaxManager + jQuery Validation Plugin working. I do not want to do old-school way of placing custom validation code as there is extensive validation implemented using the validation plugin. Any workaround to get this working would be greatly appreciated.

Thanks in advance.

Regards.
