Telerik TabStrip integrated with bootstrap column size

I have a ASP.NET webform project and want to add bootstrap. But I meet a problem for the RadTabStrip's RadTab with col-xs-6(bootstrap). The RadTabStrip's RadTabs are dynamically created by code. I also set the "col-xs-6 btn btn-primary" to RadTab's attriibute of "class". I wish I can see two columns RadTab per row in the size of xs(col-xs-6). But I still failed in the RadTab's color and arrange. Does somebody know how to solve this problem？

<telerik:RadTabStrip RenderMode="Lightweight" runat="server" ID="RadTabStripMenu" MultiPageID="RadMultiPageMenu" SelectedIndex="0" OnTabClick="RadTabStripMenu_TabClick">

for (int index = 0; index < dt.Rows.Count; index++)

{

string intOrderNo = dt.Rows[index]["intOrderNo"].ToString().Trim();

string chMenuItem = dt.Rows[index]["chMenuItem"].ToString().Trim();

string chDescritp = dt.Rows[index]["chMenuName"].ToString().Trim();

short tabIndex = Convert.ToInt16(chMenuItem.Substring(2, 3));

RadTab radTabItem = new RadTab();

radTabItem.Text = chDescritp;

radTabItem.Value = tabIndex.ToString();

radTabItem.PageViewID = "RadPageViewMenu" + tabIndex.ToString();

radTabItem.Font.Size = new FontUnit(FontSize.Large);

radTabItem.CssClass = "TabItem";

radTabItem.Attributes.Add("class", "col-xs-6 btn btn-primary");

RadTabStripMenu.Tabs.Add(radTabItem);

RadTabStripMenu.DataBind();//add 20170504

}

Every time I set skin to black I get a run time error."Telerik.Web.UI.RadWindow with ID='confirmWindow' was unable to find embedded skin with name 'Black'.

Error on Postback while using Multi-Column Headers

I am binding a radgrid to a dataset using NeedDataSource with AutoGenerateColumns set to true. I am using the following code to get Multi-Column Headers. On first load the code executes fine, but on post back it gives an error(pasted below).

The error is happening in RadGrid_ColumnCreated. When I try to access column, it is null.

In Page Load:

if (!IsPostBack)

{

GridColumnGroup columnGroup = new GridColumnGroup();

columnGroup.HeaderText = "Parent Header";

columnGroup.Name = "ParentHeader";

RadGridControl.MasterTableView.ColumnGroups.Add(columnGroup);

}

In RadGrid_ColumnCreated:

GridBoundColumn column = e.Column as GridBoundColumn;

string columnName = column.HeaderText; //--------------> Error happens here on postback.

if (columnName.Contains("Name"))

{

GridBoundColumn boundColumn = e.Column as GridBoundColumn;

boundColumn.ColumnGroupName = "ParentHeader";

}

Error:
Invalid column name:

Update vs UpdateEdited Commands

Is the Update Grid Command just the new version of the UpdateEdited Command? I just noticed that updating one of our grids was sending "Update" as the command, instead of "UpdateEdited"... I just saw "Update" mentioned in the current documentation, so I thought I should ask here.

Is there a way to filter the grid using a single text box?

I would like to have a single textbox outside the grid, and if the user types for example "ABC" all rows that on a column they have a value ABC would be displayed.

Changing the TimeZone of the DateTime fields

I have a RadGrid displaying data from a SQL DB in which the datetime is UTC.

I would like for the RadGrid to automatically change this datetime so it matches the client's timezone.

How can that be achieved?

Html encoding for Symbols

Hello,
One of the outputs for our RadEditor generated content is html reports. We need the ability to convert Symbols to html markup. Please see the example below for copyright symbol. Is there a conversion chart for RadEditor supported symbols and their html markup anywhere?

Get data from WebAPI?

I want to have a page with about a dozen different HtmlCharts on it, and I want them to all load their data in from a WebAPI controller.

I wanted to do this simply because if I have 12 different charts/graphs, I don't want end-users to have to sit and wait for the PageLoad event to gather and parse through tons of data. I'm hoping to just define all the charts on my webform and then tell jquery/javascript to grab the data and bind them asynchronously, letting them "appear" as they complete-- knowing that some charts will render much slower than others. I want people to be able to see each chart as they finish rendering rather than waiting for the whole lot to finish. I also don't want to just do them "1 by 1" synchronously.

Is this possible or am I going down the wrong path? I didn't see any examples, only something about using WCF which I'm not super familiar with.
