RadGrid - Reuse for different datasets; and have filters showing data.

(If this is the wrong section to post into, please advise and I'll repost in the proper spot.)

So I need some assistance as I have an idea of what I need, but putting it into code is the challenge. (Or pseudo code).

a) Can't I utilize the RadGrid object with different datasets depending on the 'dropdown box' selections?

b) Can't I bind the data, dynamically display headers, AND, have the dataset fields data grouped into filters?

I'm challenged, that I need different RadGrids for different datasets.

(Read between the lines, my engineer is saying it's difficult; but my experience with Telerik isn't noob, thus it doesn't sound difficult.)

Pass Multiple Parameters to RadWindow after Cell Double Click

Hello,

I am trying to pass two parameters (Red and Blue outlined in attachment) to a radWindow via a Cell double click, which I will then populate a grid. I am able to pass the datakey (Red outlined) value on row double click thanks to this demo, but have had no luck in capturing the Column name to use in the querystring.

Is there a Cell Double click event that I can use to make this happen or can this be done with Row Double click that captures the cell index I click on?

The second attachment shows the window opened based on the demo link, but how can I get the querystring URL to show:

Bklg_SupportStatusWIPDetails.aspx?MPC=ABAL1TC7XB00?AREA=DB

where Area is another parameter in my datasource that is looking for the column name.

Thank you in advance!

[Solved] Can application still use 2016 Telerik ASP.NET UI ASO.NET_AJAX download

To run a vb.net 2010 web form application, I have previously used Telerik ASP.NET UI ASO.NET_AJAX_2016 Dev.msi download files so the application would run successfully.
In the past I have found out that if I do not have the current Telerik tool installed, the application had unpredictable results. Basically when the .net application ran on the test application server, I got errors when I accessed the Telerik tool contained within the .net application. Is this still the same issue? Can I continue to use the version of the Telerik tool the application is accessing currently ? If so, can you tell me how long I can continue to use the same version of the Telerik tool?

If not, can you tell me what version of the Telerik tool I need to install?
**I am asking this question since I do not know if my latest install of the Telerik ASP.NET UI ASO.NET_AJAX_2017_1_228_Dev.msi installed correctly.

Safari bug?

We have a user using Safari 3.1 (on Mac OS X 10.4) who reports that when he clicks on the RadComboBox nothing happens. The combobox doesn't drop down as it should. Are there any known issues with RadComboBox and Mac Safari? I am running the latest version of Prometheus on the website. Here is the RadComboBox in my aspx page:

<

telerik:RadComboBox ID="rcbProcessGroup" DataSourceID="dsGetProcessGroups" runat="server" Skin="WebBlue" AppendDataBoundItems="true" Font-Size="12px" AutoPostBack="true" DataTextField="ProcGroupName" DataValueField="PgrpID" Width="196px">
<Items>
<telerik:RadComboBoxItem runat="server" Text="All Processes" Value="0" />
</Items>
</telerik:RadComboBox>

Grid doesn't fit viewport

Hi All

We have a radgrid with has several columns, that when viewed on a mobile device is too wide for the viewport. This is simply because of the number of columns.

We are using Bootstrap and the page is responding correctly.

Before I code it to hide columns on smaller devices, has anyone had this problem before? and what is the fix? Can you get the grid to scale for example?

Andy

ExportToExcel does not returns anything/does not work

While I read many posts about this issue, none seem to fit my particular problem.

I have a very simple web form, with a grid, which is not ajaxified, in server side code, I call a complex object that returns a simple list of items as a datatable and set it as datasource for my grid. The grids works and displays all OK, however when I try to export to xlsx (and actually any supported format), nothing happens after calling MasterTableView.ExportToExcel().

I did verified that the grdWarranties items is not empty and that the datasource is not lost. Below substract of the web page and the server side code to execute the export:

Protected Sub btnExport_Click(sender As Object, e As Telerik.Web.UI.ImageButtonClickEventArgs) Handles btnExport.Click

grdWarranties.Page.Response.ClearHeaders()

grdWarranties.Page.Response.Cache.SetCacheability(HttpCacheability.Private)

grdWarranties.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.Xlsx

grdWarranties.ExportSettings.IgnorePaging = False

grdWarranties.ExportSettings.ExportOnlyData = True

grdWarranties.ExportSettings.OpenInNewWindow = True

grdWarranties.MasterTableView.ExportToExcel()

End Sub

<asp:Panel runat="server">

<table class="WarrantyCheckTable" style="margin-top:15px">

<tr>

<td style="width:15%">

<telerik:RadLabel ID="RadLabel1" Text="Type or paste in your Landis+Gyr serial numbers:" runat="server" Font-Size="Small" Font-Italic="True"></telerik:RadLabel>

<telerik:RadTextBox ID="txtMSNs" runat="server" TextMode="MultiLine" BorderColor="#7AB800" BorderWidth="1px" Height="93%" Width="100%" Wrap="False" ></telerik:RadTextBox>
