I am trying to figure out how to accomplish this.  I am not sure if the RadGrid is best use

I have a data query that will return one or more records

Example - data returned may look like

UserID, User Full Name, User Status, Hire Date, Manager Name, Location, Skill Set, Last Review

And I want to format it as

Record 1

Row - User ID, User Full Name, User Status, Hire Date, Manager Name

Row - Location, Skill Set, Last Review

Next Record

Row - User ID, User Full Name, User Status, Hire Date, Manager Name

Row - Location, Skill Set, Last Review

Etc. 

I no problem filling data adapter, filling data table and then binding to grid in single row to record, but setting up multiple rows per record I am struggling. 

Thanks

Is there a JQuery version requirement for using the Telerik Web UI Controls in an ASP.Net Web Forms project?  I see the .NET 4.6.2+ but no JQuery version.

Scenario

  • The page has a left navigation panel that can be collapsed / expanded

  • On toggle, the main content container width is changed using CSS only (no page refresh)

  • On initial page load or full refresh, the grid renders correctly

  • On toggle of grid button in the expand mode only, the grid suddenly shows a horizontal scrollbar

Observed Behaviour

  • This happens only after clicking toggle ( external button written in C# code)

  • Rebinding the grid (Rebind()) or calling repaint() does not fix the issue

  • A full page refresh always fixes it. 

 

 

How can i prevent the scoll from appearing when the grid has lesser columns. the scrolls appears from _Frozen.

 

Css used for toggle small -> condensed , and condensed -> small 

.small .RadGrid .rgRow td,
.small .RadGrid .rgAltRow td,
.small .RadGrid .rgEditRow td,

.small .gridFillLayoutPanel .RadGrid_Metro .rgHeader th,
.small .gridFillLayoutPanel .RadGrid_Metro .rgGroupHeader th,
.small .RadGrid .rgRow > td,
.small .RadGrid .rgAltRow > td,
.small .RadGrid .rgEditRow > td,
.small .RadGrid .rgFilterRow > td {
    padding-left: 8px !important;
    padding-right: 8px !important;
    line-height: 32px !important;
    height: 32px !important;
    font-family: @font-tab-title;
    font-size: 12px;
    padding-top: 7px !important;
    padding-bottom: 7px !important;
    text-align: left;
}

 

.condensed .gridFillLayoutPanel .RadGrid_Metro .rgRow td,
.condensed .gridFillLayoutPanel .RadGrid_Metro .rgAltRow td,
.condensed .gridFillLayoutPanel .RadGrid_Metro .rgEditRow td
.condensed .gridFillLayoutPanel .RadGrid_Metro .rgHeader,
.condensed .gridFillLayoutPanel .RadGrid_Metro .rgGroupHeader td,
.condensed .RadGrid .rgRow > td,
.condensed .RadGrid .rgAltRow > td,
.condensed .RadGrid .rgEditRow > td,
.condensed .RadGrid .rgFilterRow > td,
.condensed .RadGrid .rgHeader th, 
.condensed .RadGrid .rgGroupHeader th {
    padding-left: 7px !important;
    padding-right: 7px !important;
    line-height: 24px !important;
    height: 24px !important;
    font-family: @font-tab-title;
    font-size: 11px !important;
    padding-top: 3px !important;
    padding-bottom: 3px !important;
    text-align: left;
}

Hello Telerik Support,

We are experiencing an issue with the RadGrid control when sorting by a single column that contains many duplicate values. The ordering of the results is inconsistent, which can confuse users. Additionally, in some cases, selecting a row causes the grid to re-sort unexpectedly, rather than navigating to the selected record’s page.

This behavior only occurs when sorting by a single column with non-unique values. When sorting by multiple columns, the ordering and navigation work as expected.

Could you please advise on:
• How to ensure stable and predictable sorting in RadGrid when sorting by columns with duplicate values?
• Best practices for maintaining consistent row selection and navigation behavior in these scenarios?

We are targeting .NET Framework 4.8.

Thank you for your assistance.

I'm trying hide a couple of columns in a RadGrid. I can do this in RadGrid1_ItemDataBound with the GrdiHeaderItem setting visible = false.

However, the output still uses space for the 2 columns that were hidden at the end of the grid.

Looking at the page source when I run my app there are 2 extra <col /> tags in <colgroup> and the <tfoot> tag has 2 extra <td></td> tags. There is the correct number of <td> tags in each row in <tr> in the table body.

Could this be from css? Is there a way in override this in RadGrid1_ItemDataBound manually?

I’m working with Telerik RadGrid and need an example where filtering is enabled on the columns and vertical scrolling is also active. Could someone direct me to a demo or sample that demonstrates this setup?

Greetings,

I have noticed today that the following demo pages are broken when using the latest versions of Chrome & Edge:

https://demos.telerik.com/aspnet-ajax/htmlchart/examples/appearance/configuringappearance/defaultcs.aspx

https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/dateaxis/defaultcs.aspx

https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/pan-zoom/defaultcs.aspx

Each of these have a series of JavaScript errors that prevent the page from working:

RadHtmlChart.js:79 Uncaught SyntaxError: Invalid or unexpected token
    at b.RadHtmlChart._parseObject (RadHtmlChart.js:79:46)

On my pageI have a RadGrid with columns containing gross and net ammounts  and a RadButton "Gross/Net". By clicking the button the grid shows it columns accordingly. Worked liek a charm.

Then I added aggregates od type "Sum" and still everything worked fine.

After that I added an aggregate od type "Custom" to one of the columns (which calculates  and shows everything as it should) but than I lost the button funcionality, clicking it does not switch the columns visibility. 

The button does:  myGrid.MasterTableView.GetColumn("mycolumn").Display = Not mybutton.Checked.
Also tried:  myGrid.MasterTableView.GetColumn("mycolumn").Visible = Not mybutton.Checked

When I attempt to add a rad grid to a page I am getting this error every time.  This is noew as I use grids all the time.

This is just added and no functionality is yet attached to the grid.
