Hello, all.

I'm just getting started in telerik charting, and I'm tasked with trying to produce a real-estate stacking plan. It's a fairly industry-standard chart that is essentially a zero-gap "StackedBar100" chart, where the items are rentable units, grouped by floor, proportioned by rentable area. So, for example, the attached data would produce, roughly, the attached chart. (The colors will be set item by item, based on other data, and the floors will be reversed, high to low, to mimic the building layout.)

I'm understanding most of what I need to do, but my stumbling point is the grouping field. How do I tell the chart that series items need to be grouped based on the "Floor" field?

As I said, I'm very unfamiliar with charting programming, in Telerik or elsewhere, so I might be getting tripped up on terminology.

Thanks!

John

SQL Error on Development Examples

Hi

I am getting the following error when trying to access certain examples on the development server:

"

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

"

I suspect this is happening due to not installing the SQL database that came with Telerik?
The reason for this is that I already have a SQL Express server running.

How do I get the database for these examples into my instance of SQL Express??

Thanks

Using Checkbox in grid to set selected value in radCombobox

Hi

I have a radGrid with a template column:

<telerik:GridTemplateColumn UniqueName="colPrimaryProcedure" HeaderText="" ItemStyle-HorizontalAlign="Center"><HeaderStyle HorizontalAlign="Center" />

<ItemTemplate>

<asp:checkbox ID="chkPrimary" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

The values in this grid also appear later down the page in a combo box. What I'm trying to do is if a checkbox is selected the same value in the combo box is also selected.

I can do this Server side, but how do I achieve this on the client. I can't find the selected value corresponding to the ticked item in the grid.

Only 1 tickbox in the grid can be true at any one time. (this is working OK)

[Solved] Issue CheckBox inside RadGrid + IE

Hello friends,

i have an issue here. as we know, checkbox's inside radgrid dont work properly(we have to put checkbox cell on edit mode, otherwise we cant update checkbox value unless we select the row first), so i made a simple js script + add an atribute to the checkbox to put it in edit mode with onmouseenter:

vb:

Dim chk As CheckBox = DirectCast(item("BlockCheck").Controls(0), CheckBox)

chk.Enabled = True

chk.Attributes.Add("onmouseenter", "changeEditor(this)")

js:

function changeEditor(sender) {

var grid = $find("<%=RadGrid1.ClientID%>");

var cell = Telerik.Web.UI.Grid.GetFirstParentByTagName(sender, "td");

var batchManager = grid.get_batchEditingManager();

grid.get_batchEditingManager().openCellForEdit(cell);

}

aspx:

<telerik:GridCheckBoxColumn DataField="BlockCheck" UniqueName="BlockCheck" AutoPostBackOnFilter="true">

<HeaderStyle ForeColor="Black" Width="20%"></HeaderStyle>

</telerik:GridCheckBoxColumn>

<telerik:GridTemplateColumn DataField="BlockCheck" Visible="false">

<ItemTemplate>

<asp:CheckBox ID="Cb1" Checked='<%# Eval("BlockCheck")%>' runat="server"/>

</ItemTemplate>

<EditItemTemplate>

<asp:CheckBox ID="Cb2" Checked='<%# Bind("BlockCheck")%>' runat="server" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

the issue is: this works wonderfull on chrome and firefox, but on internet explorer, this keeps bugging the state of the checkbox, after i changed it. its like, loosing the state on mouseout/disable celleditmode(??)
onmouseover also dont work on ie. can you guys help?

thanks in advance,
Mike

Error when sorting columns with spaces in SortExpression

Hello,

I have a grid that is already defined, with several columns, in the markup. Based on the data returned I may have to dynamically add additional columns to this grid. The additional columns can potentially have spaces in them. When setting the SortExpression property on the dynamically created GridBoundColumn I am wrapping the string value in brackets, for example GridBoundColumn.SortExpression = "[Dynamic Column Name]".

When I sort by this column I am getting the following error: [Dynamic Column Name] is neither a DataColumn nor a DataRelation for table Table.

I am creating the columns on page load when IsPostBack = false.

Any idea on how to get these things to sort?

Thanks!

two vertical scrollbars

When using combobox with RenderMode="Lightweight" and DropDownAutoWidth="Enabled" it renders two vertical scrollbars.

E.g. see attached image for the code below (data source is Dictionary<string,string>)

<telerik:RadComboBox ID="rcbCountry" runat="server"

AppendDataBoundItems="true"

DataSourceID="CountriesDataSource" DataTextField="Value" DataValueField="Key"

Width="100px" DropDownAutoWidth="Enabled"

RenderMode="Lightweight">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

Grouping: paging based on visible rows

Currently radGrid doesn't provide paging based on visual (not collapsed) rows. E.g. go to http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/grouping/grouping/defaultcs.aspx, collapse all 3 "Received" groups and radGrid show three rows only but pager reads "Item 1 to 20 of 52". Thus, if there are many groups then there is no way to see other groups on the current page by collapsing them - the only way is to go to another page which pretty inconvenient and annoying.

I'd like to have functionality similar to http://demos.devexpress.com/ASPxgridviewDemos/GroupingSorting/Grouping.aspx - try to collapse countries.

Do you have a workaround to achieve that or any plans to implement this feature?
