how to clear the exiting values before open the rad window

Hi,
I am using rad window , it display the textbox which creates dynamically.

I am using the below code.

function openWin() {

var docId = document.getElementById('cpEditor_hdnDocId').value;

var oWnd = $find("<%= radPropertyInspector.ClientID %>");

oWnd.setUrl("NZFPropertyInspector.aspx?docId=" + docId);

oWnd.show();

}

it works well.

But, my problem is , once i close the window with some value in text box in in rad window,

again i open the rad window, it shows the previous value of text boxes, then reload the new text box values.

Text boxes are created dynamically.

i need to empty the textbox before showing the rad window.

How to clear the values of item before loading?

Thanks,
Uma

Extra items being bound to RadComboBox inside a RadGrid TemplateColumn

I have a RadGrid that is bound in the code behind, on on ItemDataBound I'm doing binding to a RadComboBox that is within a TemplateColumn inside the grid:

<tel:RadGrid runat="server" ID="rgCounties" OnItemCommand="rgCounties_ItemCommand"

AutoGenerateColumns="False" OnItemDataBound="rgCountes_ItemDataBound" AllowMultiRowEdit="True"

CellSpacing="0" GridLines="None">

<MasterTableView>

<Columns>

<tel:GridBoundColumn Display="false" DataField="ID" UniqueName="SectionCountyID" />

<tel:GridTemplateColumn HeaderText="County" UniqueName="CountyColumn">

<InsertItemTemplate>

<tel:RadComboBox runat="server" ID="rgrcCounty" DataTextField="CountyName" DataValueField="ID" />

</InsertItemTemplate>

<ItemTemplate>

<tel:RadComboBox runat="server" ID="rgrcCounty" DataTextField="CountyName"

DataValueField="ID" />

</ItemTemplate>

</tel:GridTemplateColumn>

</Columns>

</MasterTableView>

</tel:RadGrid>

So they can edit the County Dropdown at will, and click a save button below.
The county dropdown is being populated from a database table, but only has entries that are not currently in the grid.

For instance, Suppose i have 5 Counties:
{Lancaster, York, Berks, Adams, Allegheny}
the Grid has 3 entries for the counties "York, Adams, Allegheny". Therefore, each combo box should have the two that are not present anywhere in the grid (Lancaster, Berks), as well as one entry for that grid row

So the grid would look like this:
Row 1: Combo with options {Lancaster, Berks, York}
Row 2: Combo with options {Lancaster, Berks, Adams}
Row 3: Combo with options {Lancaster, Berks, Allegheny}

However, the results I'm getting are:
Row 1: Combo with options {Lancaster, Berks, York}
Row 2: Combo with options {Lancaster, Berks, York, Adams}
Row 3: Combo with options {Lancaster, Berks, York, Adams, Allegheny}

Even though on Each row I'm rebinding the combobox and adding the missing one.

protected void rgCountes_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

var ditem = e.Item as GridDataItem;

var combo = ((RadComboBox)ditem["CountyColumn"].FindControl("rgrcCounty"));

var sectionCountyID = int.Parse(ditem["SectionCountyID"].Text);

var sectionCounty = Model.SectionCounties.Where(sc => sc.ID == sectionCountyID).FirstOrDefault();

combo.Bind(Model.Counties, false);

if (sectionCounty != null)

{

combo.AddOrSelectByValue(sectionCounty.CountyID.ToString(), sectionCounty.County.CountyName);

rnt.Text = sectionCounty.Percentage.ToString();

}

}

        public static bool AddOrSelectByValue(this RadComboBox combo, string value, string text)
        {
            bool tf = combo.SelectByValue(value);
            if (!tf)
            {
                combo.Items.Add(new RadComboBoxItem(text, value));
                combo.SelectByValue(value);
            }
            return tf;
        }

You can see I'm rebinding each combo and then adding a new value on a per-row basis. But it seems that on each row, thecombo.Items.Add() is being applied additively.

Any idea what I'm doing wrong or how to fix it?

thanks!

Drag and drop to change the order.

I am trying to have a grid allow me to drag and drop rows. I can get it to allow me to drag it but it doesn't save it in the new place. I'm also going to want to write it out to the database so the values are saved.

I've read all kinds of things that seem WAY to complicated - there must be an easy way to do it.

Can somebody point me in the right direction.

TIA - Jeff.

Is there a RadAjaxManagerProxy?

Since the most useful part of RadAjaxManager is the UI for defining AjaxSettings that go along with it, why not create something similar to ScriptManager and ScriptManagerProxy? This way, individual controls could have a ScriptManagerProxy, where they can define their own internal settings and update controls and then the content page (or master page) could have the top level RadAjaxManager that would aggregate all the RadAjaxManagerProxy controls from all child controls and content pages.

Thoughts?

Cant get the exact time using get_startTime()

I have a RadScheduler with intervals of 30 minutes.
I am trying to validate when the user moves an appointmente to another timeslot. I am using OnClientAppointmentMoveEnd to check the new timeslot and the new startime.
The problem is that when the user drags the appointment to, for example, 15:30, the "eventArgs.get_newStartTime()" returns "15:01".
If it drags to slot "15:00" it also shows "15:01". Why is that?
Here is a sample code where I am just trying to show a message asking the user to confirm the changes in the schedule and in the resource.

function OnClientAppointmentMoveEnd(sender, eventArgs) {

var apt = eventArgs.get_appointment();

var msg = "";

var novadata = eventArgs.get_newStartTime();

if (apt.get_start() != novadata) {

msg = "New Schedule:" + novadata.format("HH:MM") + "\r\n";

}

if (apt.get_timeSlot().get_resource(0).get_key() != eventArgs.get_targetSlot().get_resource(0).get_key()) {

msg = msg + "New therapist:" + eventArgs.get_targetSlot().get_resource(0).get_text() + "\r\n";

}

if (confirm(msg + "Confirm change?" )) {

}

else {

set_cancel(true);

}

Any ideia? Thanks.

RadGrid filtering throws null reference exception when inside a RadWindow

I have a RadGrid in a RadWindow. When I try to filter the grid it does a postback and throws this exception:

[NullReferenceException: Object reference not set to an instance of an object.]
Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) +9792
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

I found that if I put another RadGrid on the page not in a RadWindow and filter it first, then filter the RadGrid in the window, it works correctly.

To reproduce: click "Open RadWindow", enter "5" in Title filter, click the filter icon for the Title column and select "Contains"

radScheduler.SelectedDate

Howdy,

I'm writing some functionality that lists events for a specific date. The date I am using is the radScheduler.SelectedDate.

My question is about setting the radScheduler.SelectedDate. Whenever you change it on the date selector, it doesn't seem to automatically change the radScheduler.SelectedDate . The radScheduler.SelectedDate gets set when some other event is fired (i.e. changing to day view, month view, etc.....)

Is there a way to set the radScheduler.SelectedDate when the dateSelector event change?

Any help would be appreciated.

Thanks!

Justin
