[Solved] Cannot set Checked items in RadComboBox in FilterTemplate

I have a radGrid with a FilterTemplate containing a radComboBox with CheckBoxes=true.
I want to preselect a number of items in the radComboBox but that doesn't seem to work inside the filtertemplate (while it works just fine for the radComboBox outside a grid)
The grid columns and template are created in server side code, the data is loaded via a pagemethod.
I minimized my code down to this:

gridtest.aspx.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

using System.Web.Services;

namespace SMTX.Common.Web {

public partial class gridtest : System.Web.UI.Page {

protected void Page_Load(object sender, EventArgs e) {

if (!Page.IsPostBack)

initGrid();

}

public void initGrid() {

Forms.BL.EntityClasses.ViewEntity objView = Forms.BL.MyCode.ViewFactory.fetch(18);

RadGrid1.AllowFilteringByColumn = true;

GridBoundColumn objCol = new GridBoundColumn {

AllowFiltering = true,

DataField = "Field1",

HeaderText = "Field1",

DataType = Type.GetType("System.String"),

FilterTemplate = new FilterTemplateCombo()

};

RadGrid1.Columns.Add(objCol);

objCol = new GridBoundColumn {

AllowFiltering = false,

DataField = "Field2",

HeaderText = "Field2",

DataType = Type.GetType("System.String")

};

RadGrid1.Columns.Add(objCol);

ScriptManager.RegisterStartupScript(this, this.GetType(), "CallGetView", @"setTimeout(function() {radGrid_Init();} , 1000);", true);

}

[WebMethod]

public static List<dataContainer> GetData(List<GridFilterExpression> p_lstFilterExpressions) {

List<dataContainer> lstData = getDataForGrid(p_lstFilterExpressions);

return lstData;

}

public static List<dataContainer> getDataForGrid(List<GridFilterExpression> p_lstFilterExpressions) {

List<dataContainer> lstData = dataContainer.getTestData();

List<String> lstFilterValues = null;

if (p_lstFilterExpressions.Count > 0)

lstFilterValues = p_lstFilterExpressions[0].FieldValue.Split(new []{"||"}, StringSplitOptions.RemoveEmptyEntries).ToList();

if (lstFilterValues == null)

return lstData;

else

return lstData.Where(r => lstFilterValues.Contains(r.Field1)).ToList();

}

public class dataContainer {

public Object Field1 { get; set; }

public Object Field2 { get; set; }

public static List<dataContainer> getTestData() {

List<dataContainer> lstToRetrun = new List<dataContainer>();

lstToRetrun.Add(new dataContainer { Field1 = "Name1", Field2 = "Name1field2" });

lstToRetrun.Add(new dataContainer { Field1 = "Name2", Field2 = "Name2field2" });

return lstToRetrun;

}

public class FilterTemplateCombo : ITemplate {

object m_objDataSource;

public FilterTemplateCombo() {

m_objDataSource = new[] { "Name1", "Name2" };

}

public void InstantiateIn(Control objContainer) {

RadComboBox objCombobox = new RadComboBox();

objContainer.Controls.Add(objCombobox);

objCombobox.DataSource = m_objDataSource;

objCombobox.DataBind();

objCombobox.OnClientItemChecked = "RadGrid_ComboBoxMultiFilterCommand";

objCombobox.CheckBoxes = true;

foreach (RadComboBoxItem objItem in objCombobox.Items)

objItem.Checked = true;

}

}

function RadGrid_Command(sender, args) {

args.set_cancel(true);

var filterExpressions = sender.get_masterTableView().get_filterExpressions();

PageMethods.GetData(filterExpressions.toList(), RadGrid_Update);

}

function RadGrid_ComboBoxMultiFilterCommand(sender, args) {

var gridTableView = sender.get_parent().get_parent().get_masterTableView();

var arr_objItems = sender.get_checkedItems();

if (arr_objItems.length > 0) {

var strData = "";

for (var i = 0; i < arr_objItems.length; i++)

strData += "||" + arr_objItems[i].get_value();

gridTableView.filter("Field1", strData, Telerik.Web.UI.GridFilterFunction.Custom);

} else {

gridTableView.filter("Field1", "", Telerik.Web.UI.GridFilterFunction.NoFilter);

}

function RadGrid_Update(result) {

var tableView = $find("RadGrid1").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();

}

</script>

</telerik:RadScriptBlock>

</form>

</body>

</html>

I expect the radComboBox filter in Field1 to have it's 2 items checked, but that doesn't seem to be the case, although they were checked in the code.

decrease the opacity of the oval color

Hi,

It is possible to decrease the opacity of the oval color so that some degree of
transparency is maintained even when there are many overlapping ovals? In the
center area of the screenshot below, it’s not possible to see distinct ovals
because the overlapping reaches full opacity very quickly.

Problem with autocompletebox

<telerik:RadAutoCompleteBox ID="RadOilSystem" runat="server" AllowCustomEntry="True"
DropDownHeight="400px" EmptyMessage="供油系统" InputType="Text" Skin="Forest" Width="100%">
<WebServiceSettings Method="GetOilSystem" Path="aDefault.aspx" />

Delete item from ListBox

I have following code snippet used for deleteing an selected item from ListBox. Following is the aspx code

<

telerik:RadListBox ID="rlbTag" runat="server" AutoPostBack="false" OnClientItemDoubleClicked="DeleteTags()" Width="250" EnableEmbeddedSkins="true" Height="80px" AllowAutomaticUpdates="true">

<tr>

<td align="left" ><asp:Label ID="lblTags" Text='<%# DataBinder.Eval(Container, "Text") %>' runat="server"></asp:Label></td>

<%

--<asp:CheckBox id="cbUsers" runat="server" OnClick="checkboxReportClick(event);" Text='<%# DataBinder.Eval(Container, "Text") %>' />--%>

</tr>

</table>

</ItemTemplate>

</telerik:RadListBox>

</td>

Following is the implementation of removeItem method which will be triggered when user click on delete button in List Box item template

function

removeItem(e)

{

var RdListBox=$find("<%= rlbTag.ClientID %>");

var item = RdListBox.get_selectedItem();

RdListBox._selectedIndex = 0;

RdListBox.trackChanges();

RdListBox.get_items().remove(item);

RdListBox.commitChanges();

}

When first time user clicks delete button to remove an item, selected item is gettiung null. Seconmd time it gets deleted from the list.
Can anyone help me to acheive remove functionality on cleint side?

change the years you are able to see in the MonthYearFastNavigation

We limit the selection of dates to the last 5 years, however by default the MonthYearFastNavigation shows the last 4 years, current year and the next 5 years. I was wondering if the user is able to change is so that dates that are not selectable won't show up either and that the user can see all the years that they can select from.

For the current year the user can see the years 2010 to 2019. But what we really want to show is 2009 to 2014 because those are the only years that the user can select dates from.

Filtering columns with JOIN

I'm using JOINS and alias in the SQL request to bind data to a Radgrid.

It's working fine. However, I've activated "Filtering by column" and it doesn't work at all, for columns with alias and join.

Here is the error I get:
"Invalid name 'NameColumn'"

Could anyone help, please?
