Load from database record when filter changes

Hello,
I will like to load from the database the filter expressions and not just hide the rows.
I set custom filter to true but when I set the grid's datasource to the new results set, I get an error when I try to click a row or change the filter expression.

Is there a way I can load from the database when filter expression is changing without getting an error message from the gird?

Thank you

Cannot view programmatically added RadListBoxItems (RadListbox is not refreshed)

Hi everybody,

I have a RadGrid which has checkbox as GridTemplateColumn. When the checkbox is clicked, I want to add a new item to a RadListbox.
I use the click event and add RadListBoxItems to my RadListbox, but the new item is not rendered in browser. I can also add a new item using a button's click event. After button click event, I can see both newly added items. So the problem is, a new item cannot be seen after checkbox click event.

Am I doing something wrong or it this a bug?
(Telerik assembly version: v4.0.30319)

Below is the related code:

<telerik:RadGrid ID="rgStudentList" runat="server" AllowFilteringByColumn="True"

AllowSorting="True" CellSpacing="0" Enabled="false" GridLines="None" GroupingSettings-CaseSensitive="false"

OnItemCommand="rgOgrenciListesi_ItemCommand" OnNeedDataSource="rgOgrenciListesi_NeedDataSource"

SortingSettings-SortToolTip="">

<GroupingSettings CaseSensitive="False" />

<SortingSettings SortToolTip="" />

<MasterTableView AllowPaging="true" AutoGenerateColumns="False" DataKeyNames="No"

PageSize="10">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn AllowFiltering="true" AllowSorting="true" AutoPostBackOnFilter="true"

CurrentFilterFunction="StartsWith" DataField="TCKimlikNo" FilterControlAltText="Filter column1 column"

>

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Seç" AllowFiltering="false">

<ItemTemplate>

<asp:CheckBox ID="chkI" runat="server" AutoPostBack="true" OnCheckedChanged="chkI_CheckedChanged" />

</ItemTemplate>

<HeaderTemplate>

<asp:CheckBox ID="chkH" runat="server" AutoPostBack="true"

OnCheckedChanged="chkH_CheckedChanged" />

</HeaderTemplate>

</telerik:GridTemplateColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

<NoRecordsTemplate>

<center>

blah blah</center>

</NoRecordsTemplate>

</MasterTableView>

<FilterMenu EnableImageSprites="true">

</FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

protected void chkI_CheckedChanged(object sender, EventArgs e)

{

CheckBox chkI = sender as CheckBox;

String student= ((GridDataItem)chkI.Parent.Parent).Cells[3].Text;

rlbOgrNo.Items.Add(new RadListBoxItem(student, student));

}

After the checkbox checked changed event, I cannot see the new item added. (Not rendered.)

I tried many things but no hope. Any help is appreciated.
Thanks.

ToolTip Control ?

Hi,

       We are trying to upgrade the look of our ToolTips in our products. We are focusing our efforts on the ToolTips that display information about the object that is currently hovered in the graphical zones of our products. We want to be able to display some of the properties of that object arranged in some fashionable way. You could find an example (sketched in Paint) of the new ToolTips we want in the attached files.

       Our products are built on top of the Microsoft .NET WinForms framework with some specific WPF controls like your ScheduleView WPF RadControl. Our graphical areas are just ordinary WinForms Panels that we use as drawing surfaces (with GDI API).

Our current requirements specifies that only include static information would be displayed in the ToolTip, but it is quite possible in a short timeline that we get the requirements to put some interactive content in the ToolTip like user actions (buttons or link buttons, …).

I would be please to know if you offer any ToolTip control that we could use to accomplish our needs. We would be at ease to use any kind of technology (WinForms, WPF/XAML, HTML, ...). Our only restraint is that our graphical areas are built with WinForms. Do you have any recommendations to give us?

Thanks a lot.

Numerical (non-Categorical) X Axis

Hello,

I cannot seem to get an X Axis to behave as a non-categorical type of axis. In other words, not only do we have numerical data in the Y-Axis, but also we've got numerical data in the X-Axis. Is this possible with Telerik RadChartView? Or does the X Axis always get treated like a "category"? If so, how?

Thank you...

Regards,
