Calender in RadDockZone

Hi Everyone,

I m newly working on Rad Controls. So, please clarify me on my below requirements.

1. Can we add Calender (Dynamic) directly to RadZone. or we have to do it through RadDock.???
2. I need calender to start from current month with only right arrow beside it. Only clicking this right arrow, we have to navigate to next month and at the same time left arrow should be enabled.
3. Is Calendar can be minimized ???

Its would helpful for me if you suggest anything for above. Atleast some hints.

Thanks and Regards

RadGrid custom filter does not generate the .aspx.designer files

Hello,

I implemented your solution for a custom column filter from the link below:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx

This works when running it, but it has a big problem (I'm on VS 2008 SP1): the .aspx.desginer file does regenerate anymore!
I tried deleting it, and then Convert to Web Application from the .aspx file (which should generate the .aspx.designer file), but I got the error:
"Generation of designer file failed: unknown server tag <custom ...."
Once I remove this tag (<custom....), the generation of .aspx.designer file works very well.

Thanks,
Toni

Edit/Add RadListView Items via RadWindow Dialog

I am working on a contact list similar to the demos for the RadListView. What I want to do is have the items bind server side. This could be via labels for each data field for an item or inputs like textboxes. Then on each item bound there would be an edit button. When the edit button is clicked then via client side script the values of the item would be passed to a dialog radwindow where they can edit it. When done they would click and ok button and then the dialog would pass the values back, they would be added to the ListView as a new item. Well the dialog was easy to do, but its the sending and receiving from the ListView that is proving difficult. The only option I see is custom attributes on the fields in the item and using jquery selectors.

So my question is whether there is a good sample code of editing the items of a list view client side and particularly in a rad window?

Secondly is there a way to have say either via loading it via the page or a service call back to the page the data list for a list view, bind it client side and then do similar what I described previously.

Thanks.

Submitting form to show grid

I am very new at this so if this is too easy a question, please refer me to an example page/video. Otherwise here's my quesion.

I have a table with 3 columns for example

ProductName
ProductColor (RED,WHITE,BLUE)
ProductDate

What I want to do is create a form to search for products by allowing partial name of the product, allow users to choose from a listbox to select one or more colors, and a productdate begin and productdate end to find out the timeframe of product creation.

I know how to create a radgrid and display it using a selected query.

How would I go about creating the initial search screen and using the form fields to modify the grid?

Any pointers, samples appreciated!

[Solved] Change Value on ItemDataBound RadGrid

I want the code where i can bound the data code behind and access and change all the bind controls on the ItemDataBound Event
see the code.

<telerik:RadGrid ID="RadGrid1" runat="server"

onitemcommand="RadGrid1_ItemCommand" GridLines="None"

onitemdatabound="RadGrid1_ItemDataBound">

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn HeaderText="CompanyName" UniqueName="CompanyName">

<EditItemTemplate>

<asp:TextBox runat="server"></asp:TextBox>

</EditItemTemplate>

<ItemTemplate>

<asp:Label runat="server"><%# Eval("CompanyName")%></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

</telerik:RadGrid>

This is my c# code

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

LoadData();

}

private void LoadData()

{

		// done some binding code

RadGrid1.DataSource = gd.GetDataTable("SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM Customers");

}

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

// what i have to do for the stuff for example

}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.AlternatingItem || e.Item.ItemType == GridItemType.Item)

{

GridItem item = default(GridItem);

// get the label value on databound and change it.

}

[Solved] Telerik radgrid paging in webshop, breaks when changing product amount on last page

I'm having some problems with one of our webshops. A Telerik radgrid works as the cart and lists all products currently in the cart. The paging on the Radgrid correctly splits the cart view into different pages. The problem occurs when one manually tries to change the amount of a product, but only if the product is on the LAST page of the radgrid and only if the number of products are less than the page size limit.

I have figured it out as much as the radgrid believes there are always an even amount of products, based on the radgrid's page size.

The crash occurs in the tbQuantity_TextChanged event handler, more specific when var shopItemID = Convert.ToInt32(item.GetDataKeyValue("ID")); is called for an item that doesn't exist on this page, but on another page.

The exception is

System.ArgumentOutOfRangeException was unhandled by user code

Message=Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

I've been trying to work something out with custom paging, but no luck so far, so I'm still using this code, only changed PageSize to 100 so the shop won't crash that easily. ;)

Thanks in advance!

RadComboBox Error: JavaScript runtime error: Unable to get property 'documentElement' of undefined or null reference

I upgrade to IE 10 today and was debugging my website that uses Telerik AJAX Controls (Version 2011.2.915.40) and am getting a

JavaScript runtime error: Unable to get property 'documentElement' of undefined or null reference

this happens when I click the arrow on the RadComboBox (also happens when I hover over a RadGrid).
I noticed that it happens only when I am debugging the site on IE10 (Even happens if I choose 'Start without debugging' option in VS 2010). I found that the java script error is occurred inside dynamically loaded java script file “Telerik.Web.UI.Common.Core.js” at statement (var C=a.document.documentElement

) by HttpHandler “Telerik.Web.UI.WebResource.axd” for Telerik control.

If I host the site on IIS 7.5 and open it in IE 10, then I don't get the JavaScript error, however the RadComboBox does not drop down.
