Filtering

I need some explanation beyond the two examples in the documentation. I am just not understanding filtering. Not true I understand the concept of filtering I am having problems with implementation.

I have a basic grid which I am filling with data from persistent storage (i.e. in the Current Session). On Page_Load I simply assign the storage for a particular table to the grid data source and bind. Simple. When sorting and paging happen I basically do the same thing. But filtering. That is a whole other ball game! I do not see an Event that I can use to rebind the data. I am assuming that the Grid or TableView handles the actual filtering and I do not need to provide any sort of filtering function.

The filtering that is offered is more than adequate for my needs I just need to know what I have to do to get an implementation going.

Thanks,
Doug

Grid Not Working Inside jQuery Colorbox

We're trying to get our grid to be fully functional inside a colorbox (http://colorpowered.com/colorbox/). The grid works fine on the page itself, but when inside a colorbox the grid loses all interactive elements (no selecting rows, changing pages, etc.).

For example:

<div>

<div id="grid_container">

<form id="form0" runat="server">

<telerik:RadScriptManager id="RadScriptManager0" runat="server" />

<telerik:RadAjaxManager id="RadAjaxManager0" EnablePageHeadUpdate="false" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid0">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid0" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid ID="RadGrid0" runat="server" AllowPaging="True" AllowSorting="True" AllowAutomaticUpdates="True" DataSourceID="ObjectDataSource0" GridLines="Vertical" PageSize="10" Skin="Telerik">

...

</telerik:RadGrid>

</form>

</div>

The above works just fine.

However, when colorbox is added:

<div style="display:none;">

<div id="grid_container">

<form id="form0" runat="server">

<telerik:RadScriptManager id="RadScriptManager0" runat="server" />

<telerik:RadAjaxManager id="RadAjaxManager0" EnablePageHeadUpdate="false" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid0">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid0" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid ID="RadGrid0" runat="server" AllowPaging="True" AllowSorting="True" AllowAutomaticUpdates="True" DataSourceID="ObjectDataSource0" GridLines="Vertical" PageSize="10" Skin="Telerik">

...

</telerik:RadGrid>

</form>

</div>

<script type="text/javascript">

function openGrid() {

jQuery.colorbox({ innerWidth: "800", innerHeight: "350", opacity: 0.5, inline: true, scrolling: false, href: "#grid_container" });

}

</script>

This does not work correctly; the colorbox opens but the grid has the issues described above.

I'm not sure how to go about fixing this, so I'd appreciate some help if possible. Thanks.

Export to Pdf issue when using Template Columns Programmatically

I have a RadGrid with template columns which are generated at runtime and added to a placeholder control on Page_Init.

Export to Excel and Word work fine using the built-in export features. Export to Pdf doesn't work properly in the sense that the template columns are not exported in the final pdf file. Only the GridBoundColumns are exported.

I have also set ExportOnlyData = false but didn't fix that issue.

Any clues?

Thanks,

Grid

Multi valued custom field editor

I'm attempting to create a custom field editor, and using the RadDropDownFilter example as a guide. My custom editor however has multiple fields - two text boxes, and two combo boxes.

When using the example code, on a postback the ArrayList in the SetEditorValues method only contains a single value - not the values entered for all four controls. The ExtractValues method does seem to be outputting an ArrayList with four elements.

Any thoughts? I'm guessing the issue might be that the inherited class - RadFilterDataFieldEditor - doesn't support multiple values? Should I be deriving from some other class? Code for the custom editor:

public class RadFilterRangeValueTypeStrategy : RadFilterDataFieldEditor

{

private RadComboBox _combo_ValueType;

private RadComboBox _combo_Strategy;

private RadTextBox _textMin;

private RadTextBox _textMax;

protected override void CopySettings(RadFilterDataFieldEditor baseEditor)

{

base.CopySettings(baseEditor);

var editor = baseEditor as RadFilterRangeValueTypeStrategy;

if (editor != null)

{

DataSource_ValueType = editor.DataSource_ValueType;

DataTextField_ValueType = editor.DataTextField_ValueType;

DataValueField_ValueType = editor.DataValueField_ValueType;

DataSource_Strategy = editor.DataSource_Strategy;

DataTextField_Strategy = editor.DataTextField_Strategy;

DataValueField_Strategy = editor.DataValueField_Strategy;

MinValue = editor.MinValue;

MaxValue = editor.MaxValue;

}

public override System.Collections.ArrayList ExtractValues()

{

ArrayList list = new ArrayList();

list.Add(_combo_ValueType.SelectedValue);

list.Add(_combo_Strategy.SelectedValue);

list.Add(_textMin.Text);

list.Add(_textMax.Text);

return list;

}

public override void InitializeEditor(System.Web.UI.Control container)

{

Label minLabel = new Label();

minLabel.Text = "Min: ";

container.Controls.Add(minLabel);

_textMin = new RadTextBox();

_textMin.ID = "MinValue";

_textMin.Text = MinValue;

_textMin.Width = Unit.Pixel(30);

container.Controls.Add(_textMin);

Label maxLabel = new Label();

maxLabel.Text = " Max: ";

container.Controls.Add(maxLabel);

_textMax = new RadTextBox();

_textMax.ID = "MaxValue";

_textMax.Text = MaxValue;

_textMax.Width = Unit.Pixel(30);

container.Controls.Add(_textMax);

Label valueTypeLabel = new Label();

valueTypeLabel.Text = " Value Type: ";

container.Controls.Add(valueTypeLabel);

_combo_ValueType = new RadComboBox();

_combo_ValueType.ID = "ValueTypeCombo";

_combo_ValueType.DataTextField = DataTextField_ValueType;

_combo_ValueType.DataValueField = DataValueField_ValueType;

_combo_ValueType.DataSource = DataSource_ValueType;

_combo_ValueType.DataBind();

_combo_ValueType.Width = Unit.Pixel(30);

container.Controls.Add(_combo_ValueType);

Label strategyLabel = new Label();

strategyLabel.Text = " Strategy: ";

container.Controls.Add(strategyLabel);

_combo_Strategy = new RadComboBox();

_combo_Strategy.ID = "StrategyCombo";

_combo_Strategy.DataValueField = DataValueField_Strategy;

_combo_Strategy.DataSource = DataSource_Strategy;

_combo_Strategy.DataBind();

_combo_Strategy.Width = Unit.Pixel(40);

container.Controls.Add(_combo_Strategy);

}

Set focus on ajax call

Hi,

I have a RadGrid with RadNumericTextBox. One of the RadNumericTextBox has a event that fires up when the content is changed.
The problem is that after the event is called I wish to set focus in another text box in the grid but it doesn't happens anything, no expections, no focus just like I hadn't the last line of the code bellow. Notice that I have the RadGrid wraped in a Ajax UpdatedControls

Here is the changed event:

protected void txt2_Changed(object sender, EventArgs e)

{

RadNumericTextBox txt1 = (RadNumericTextBox)((RadNumericTextBox)sender).Parent.FindControl("txt1");

RadNumericTextBox txt2 = (RadNumericTextBox)sender;

RadNumericTextBox txt3 = (RadNumericTextBox)((RadNumericTextBox)sender).Parent.FindControl("txt3");

txt3.Value = txt2.Value * (txt1.Value / 100);

RadAjaxManager1.ResponseScripts.Add(String.Format("$find('{0}').focus();", txt3.ClientID));

}

The assembly with display name 'Telerik.Web.UI.Skins' failed to load

I am running the trial version of Telerik controls on a windows 7 64 bit os.
I am running Visual Studio 2008.

I have just downloaded the trial version and am in the process of simply validating that the controls work on a copy of my production web project and added the Rad Date Input and the Rad Date Picker.
I am able to build the project without issue.
However when I attempt to run the project in the environment i get the following error when accessing the page where I added the controls.

* Note that in attempting to resolve this I've added a reference to the designer to my project

BindingFailure was detected

Message: The assembly with display name 'Telerik.Web.UI.Skins' failed to load in the 'Load' binding context of the AppDomain with ID 2.

I'm kind of dead in the water. I would appreciate any help / suggestions.

Thanks
