Hello,
I have used the http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/clienteditbatchupdates/defaultcs.aspx example as base of my app. I don't know how to do when doucle click in a date column to appear the datepicker to select a different date.
I have this in the UpdateValues(grid) javascript function:

case "date":

HideEditor(editedCell, "textbox");

break;

I also added this code on the grid column:

<telerik:GridTemplateColumn UniqueName="date" SortExpression="date" AutoPostBackOnFilter="true"

HeaderText="DateTimeCol" HeaderStyle-Width="10%" AllowFiltering="true" DataField="date">

<ItemTemplate>

<asp:Label ID="lblDate" runat="server" Text='<%# Eval("date") %>' />

<telerik:RadDateTimePicker runat="server" ID="txtDate" DbSelectedDate='<%# Eval("date") %>'

Style="display: none">

</telerik:RadDateTimePicker >

</ItemTemplate>

<InsertItemTemplate>

<telerik:RadDateTimePicker runat="server" ID="dateInsert" Width="95%">

</telerik:RadDateTimePicker>

<asp:RequiredFieldValidator ID="RequiredFieldValidator4a" runat="server" ErrorMessage="* Required Field"

ControlToValidate="dateInsert" BackColor="Red" BorderColor="#FF0066" BorderStyle="Solid">

</asp:RequiredFieldValidator>

</InsertItemTemplate>

<EditItemTemplate>

<telerik:RadDateTimePicker runat="server" ID="dateEdit" Width="95%" DbSelectedDate='<%# Eval("date") %>'>

</telerik:RadDateTimePicker >

<asp:RequiredFieldValidator ID="RequiredFieldValidator4b" runat="server" ErrorMessage="* Required Field"

ControlToValidate="dateEdit" CssClass="error" >

</asp:RequiredFieldValidator>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Anybody knows what is the problem?
Thanks in advanced;
Jon

[Solved] Get parent RadListBoxItem from child control inside item's template?

Say I have a RadListBox, and inside the ItemTemplate for each item, I have two RadComboBox controls, a RadTextBox control, and a RadButton control.   I capture the button click in the RadButton's OnClientClicked event handler.

Inside the OnClientClicked event handler, I want to get a reference to the parent list item, so that I can I can delete that item.

For example:

function Button_OnClientClicked(button)
{
    var listBox = $find('MyListBox.ClientID');
    var itemContainingTheButtonThatWasClicked = /* this is what I need to know    */
    listBox.get_items().remove(itemContainingTheButtonThatWasClicked);
}

Thanks

Skin-problem with sub tabs (2009 Q1)

Hi,

I have a problem with the skin on sub-tabs on a RadTabStrip. The sub-items have no skin and it is impossible to see which of the sub-tabs are selected.

The same problem can be seen on this page:

http://demos.telerik.com/aspnet-ajax/tabstrip/examples/serverside/serverevents/defaultcs.aspx

I also created a small example showing the problem

<telerik:RadTabStrip ID="RadTabStrip11111" runat="server" EnableAjaxSkinRendering="true" Skin="Vista" CausesValidation="false" SelectedIndex="0" >

<Tabs>

<telerik:RadTab Text="aaa">

<Tabs>

<telerik:RadTab Text="Sub 1"></telerik:RadTab>

<telerik:RadTab Text="Sub 2"></telerik:RadTab>

</Tabs>

</telerik:RadTab>

<telerik:RadTab Text="bbb"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

just can't seem to figure these out...

I have a couple of questions about some of the functionality of the rotator when in coverflow.

1) Is there a specific property to turn on to allow the reflection? I have set the rotatortype to coverflow but there is no reflection.

2) I have taken the code from the coverflow sample here. But I want to add functionality such that when the user double clicks the picture that is currently being shown, then I want to show that picture in a larger image.

Thanks in advance,
Lee

Client file Save in Grid

Hello! I'm having this problem (I need at the click of a button to save the file on the client side. The button is in editformsettings in Grid!
<asp:Button ID="ButSave" runat="server" Text="Save" CommandName="SaveAnket"/>
Grid event!
void Grid_ItemCommand (object sender, GridCommandEventArgs e)
        {
                if (e.CommandName == "SaveAnket")
                {
                    SaveBlankOnClient ();
                }
       }
protected void SaveBlankOnClient ()
        {
            string filename = "TextFile.txt";
            string longPath = MapPath (filename);
            Response.ContentType = "APPLICATION / OCTET-STREAM";
            string disHeader = "Attachment; Filename = \" "+ filename +" \ "";
            Response.AppendHeader ("Content-Disposition", disHeader);
            System.IO.FileInfo fileToDownload = new System.IO.FileInfo (longPath);
            Response.Flush ();
            Response.WriteFile (longPath);
            Response.End ();
        }

This operation does not work for me from the grid ... But in an ordinary button, it saves the file! I understand this is due to postback? How save file from the Grid? Help please)))

IE7 slow with RadGrid

We have a data intensive application and in one particular page, we have a Rad Grid display 180 columns/10rows of data. The page works well in IE8 and takes about 10 seconds to load, but the same page takes one and a half minute to load in IE7.

We know that IE7 Javascript is slower than IE8, but the difference in rendering times between these two browsers is very high. Are there any suggestions to improve the performance in IE7?

RadGrid Custom Databinding, Sorting, Filtering & Paging without using NeedDataSource Event

Hello,

I have come across a special scenario in the web app i am developing where I need to implement custom databinding. That is i need to bind my radgrid without using its NeedDataSource Event. I want something like this (traditional ASP.NET GridView way) :
myRadGrid.DataSource= myDataSet;
myRadGrid.DataBind();
And because of this, I also need to implement custom sorting, filtering and paging.
It will be very nice if you could post a sample app with the code implementing all of the above requirements.

Localization of FooterAggregateFormatString

Hi,

I have a Grid which has a couple of aggregated footers. They even work OK.
However, I cannot get it to display localized values. This is the markup I'm using:

<telerik:GridNumericColumn DataField="Quantity" DataType="System.Int32" UniqueName="Quantity"

FooterAggregateFormatString="<%$ Resources:strings,strNumberOfProducts%>" Aggregate="Sum">

<HeaderStyle HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Right" Width="50" />

</telerik:GridNumericColumn>

It correctly picks up the default (English) string but never picks up the localized version - although all the other parts of the grid appear localized.
I even tried to set the Culture property of the grid, but no luck.

Any idea on what I'm doing wrong?

Filtering datetime range in a custom filtering column

Hi,

I'm evaluating the RadGrid control and I have problems with filters.

I have a datetime column and I want to add a filter for filtering between two dates. If I use a GridDateTimeColumn I can use a RadDatePicker in the filter, but only for one date (not a range).

After studying the sample 'Filtering range with RadDatePicker instances in a custom filtering column' you provide in the code library (code library article), I think it could be a solution.

I've used the sample code to create in my app a custom templated column and the filtering process works fine, but there is a problem:
- I choose two dates in the combo and apply the filter, the filtering works fine.
- If I apply the filter of another column (without clearing the filter applied to datetime), the datetime filter is cleared and only remains the filter of the other column.

How can I apply filters in other columns after datetime filtering without loosing the datetime filter?

Thanks in advance,
John.
