Hi

I have a problem with AJAX.
AJAX update field that not specified in configuration. Can you tell me why ajax updated "textbox2" after I change the RadComboBox index?
(here is a simplified code of my application)


<telerik:RadAjaxLoadingPanel ID="rlpLoadingPanel" runat="server" Skin="Default" />
    <telerik:RadAjaxManagerProxy ID="RadAjaxManager1" runat="server">
        <AjaxSettings>

            <telerik:AjaxSetting AjaxControlID="cmbTest">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="textBox1" LoadingPanelID="rlpLoadingPanel" />
                </UpdatedControls>
            </telerik:AjaxSetting>


            <telerik:AjaxSetting AjaxControlID="tButton">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="myPanel1" LoadingPanelID="rlpLoadingPanel" />
                </UpdatedControls>
            </telerik:AjaxSetting>

        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>

    <asp:Panel runat="server" ID="myPanel1">

        <telerik:RadComboBox ID="cmbTest" runat="server" AutoPostBack="true" OnSelectedIndexChanged="cmbTest_SelectedIndexChanged">
            <Items>
                <telerik:RadComboBoxItem runat="server" Text="test 1" />
                <telerik:RadComboBoxItem runat="server" Text="test 2" />
                <telerik:RadComboBoxItem runat="server" Text="test 3" />
                <telerik:RadComboBoxItem runat="server" Text="test 4" />
                <telerik:RadComboBoxItem runat="server" Text="test 5" />
                <telerik:RadComboBoxItem runat="server" Text="test 6" />
                <telerik:RadComboBoxItem runat="server" Text="test 7" />
            </Items>
        </telerik:RadComboBox>
        <br />
        <br />
        <telerik:RadTextBox runat="server" ID="textBox1"></telerik:RadTextBox>
        <br />
        <telerik:RadTextBox runat="server" ID="textBox2"></telerik:RadTextBox>
    </asp:Panel>

    <asp:Panel runat="server" ID="myPanel2">
        <telerik:RadButton runat="server" ID="tButton" OnClick="tButton_Click" Text="Button"></telerik:RadButton>
    </asp:Panel>




This is code on server side

        protected void cmbTest_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
        {            
            textBox1.Text = "textValue1";
            textBox2.Text = "textValue2";
        }


Whne I move

<telerik:AjaxSetting AjaxControlID="tButton">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="myPanel1" LoadingPanelID="rlpLoadingPanel" />
                </UpdatedControls>
            </telerik:AjaxSetting>

from my ajax configuration everythis is work normal. I dont understand the link between this and changing the RadComboBox index. Why "myPanel1" have inbluence on this?

Hello

how we can change animation , i want to load each image , to leave by the left , right to left , each one.

Like this site in : "Notre agence vous propose" :

http://www.sextantfrance.fr/

Hello,

Here is my situation:

I have a RadGrid with a List<MyObject> as the datasource. The MyObject class has a property of Deleted on it which is a boolean.

My requirement is to filter to show only MyObjects in the RadGrid that have a Deleted propery of false. Hiding MyObjects that have a Deleted value of true.

For some reason I cannot figure out how to filter my RadGrid on the Deleted property.

Here are some of my attempts:

RadGrid1.MasterTableView.FilterExpression = "Deleted = false";
RadGrid1.MasterTableView.FilterExpression = "Deleted = 'false'";
RadGrid1.MasterTableView.FilterExpression = "Deleted is false";
RadGrid1.MasterTableView.FilterExpression = "NOT Deleted";

If anyone knows what I am doing wrong, please point me in the right direction.

Thanks,

TMP

 

I am trying to implement a custom filter using the DropDownList control as documented in
http://www.telerik.com/help/aspnet-ajax/grid-filtering-with-dropdownlist.html

However, I am generating the RadGrid columns at runtime in the Page_Load event.

I receive the error "Exception of type 'System.Web.HttpUnhandledException' was thrown. "  when I try to filter the data. The grid and data load correctly. I receive the error only when I try to filter the data. The exception is trapped in the GLobal.asax. I cannot determine what is throwing the exception.

The RadGrid filtering works fine if I do not use the MyCustomFilteringColumn and simply use the GridBoundColumn for all columns that are created.

The project uses the Adventure Works 2008R2 database. I am displaying all records from the DimCustomer table. The "FirstName" column implements the custom control  "MyCustomFilteringColumn : GridBoundColumn". All other columns are "GridBoundColumn".

I'm not sure what I'm missing. Any help would be greatly appreciated.

Thanks,
Mike

I created my own  "Template" column. Everything works ok. But when I add
a child hierarchy and expand any row, the values of that column in the
father grid are lost.

Any suggestions on this?

I added part of my code to show the situation.

Code:

public class MyGridTemplateColumn : GridTemplateColumn
{
    public override void Initialize()
    {
        base.Initialize();

        HeaderStyle.Width = Unit.Pixel(105);
        HeaderText = "State";
        UniqueName = "StateCol";

        DataField = "StateId";
        DataType = typeof(byte);

        var _dataSource = new List<KeyValuePair<int, string>>
        {
            new KeyValuePair<int, string>(1, "Active"),
            new KeyValuePair<int, string>(2, "Deleted"),
            new KeyValuePair<int, string>(3, "Inactive"),
            new KeyValuePair<int, string>(6, "Other")
        };

        ItemTemplate = new MyItemTemplate(this.DataField, _dataSource);
        EditItemTemplate = new MyEditItemTemplate(this.DataField, _dataSource);
    }

    public override GridColumn Clone()
    {
        var res = new MyGridTemplateColumn();
        res.CopyBaseProperties(this);

        return res;
    }

    private class MyItemTemplate : ITemplate
    {
        private readonly string _dataField;
       
private readonly List<KeyValuePair<int, string>>
_dataSource = new List<KeyValuePair<int, string>>();

        public MyItemTemplate(string dataField, List<KeyValuePair<int, string>> origenDatos)
        {
            _dataField = dataField;
            _dataSource = origenDatos;
        }

        public void InstantiateIn(System.Web.UI.Control container)
        {
            var lControl = new LiteralControl { ID = _dataField + "_lControl" };
            lControl.DataBinding += lControl_DataBinding;
            container.Controls.Add(lControl);
        }

        private void lControl_DataBinding(object sender, EventArgs e)
        {
            var l = (LiteralControl)sender;
            var value = l.NamingContainer.GetFieldValue("DataItem." + _dataField);
            if (value != null)
                l.Text = _dataSource.FirstOrDefault(s=>s.Key == (int)value).Value;
        }
    }

    {
        private readonly string _dataField;

_dataSource = new List<KeyValuePair<int, string>>();

        public MyEditItemTemplate(string dataField, List<KeyValuePair<int, string>> origenDatos)
        {
            _dataField = dataField;
            _dataSource = origenDatos;
        }

        public void InstantiateIn(System.Web.UI.Control container)
        {
            var rcBox = new RadComboBox
            {
                ID = _dataField + "_RadComboBox",
                DataTextField = "Value",
                DataValueField = "Key",
                DataSource = _dataSource
            };

            rcBox.DataBinding += rcBox_DataBinding;
            container.Controls.Add(rcBox);
        }

        public IOrderedDictionary ExtractValues(Control container)
        {
            var dictionary = new OrderedDictionary
            {
                {_dataField, (container.FindControl(_dataField + "_RadComboBox") as RadComboBox).SelectedValue}
            };
            return dictionary;
        }

Hi, we are in the process of upgrading some grids from Infragistics Ultrawebgrid  to Telerik Controls.  We are under some time constraints due to enforced IE11 upgrade.  The grid I am working with is very simple.  It is straight data entry of requsition details.  It can be one or many lines.  Is the RadGrid appropriate for this?  I have tried using it and am struggling a bit.  I don't want to bind to a data source as there won't be any data on inital load of the screen.  When the user is done inputting all of the data, I then want to insert detail lines into database.  How do I create a simple input grid?

Thanks and sorry for such a rookie question!
