Hi,

I need to select 1 row in a radgrid ( a parameter is passed in url like myPage.aspx?ID=93 )

If the row to select is in the first page displayed of the radgrid, this is OK.

However, if the row to select is, for example, in the page 5, this don't work

I do so in PreRender:

        protected void Grid_Version_PreRender(object sender, EventArgs e)
        {
            if (!IsPostBack && SelectedRecetteVersion != null)
            {
                foreach (GridDataItem item in Grid_ArticleRecette.MasterTableView.Items)
                {
                    if (item.GetDataKeyValue("RecetteID").ToString() == myID)
                    {
                        item.Selected = true;
                    }
                }
            }

I need to display to good page with the row selected

Thanks for your help please

RadGrid Up/Down navigation while in edit mode

We have a requirement where user wanted to use the up/down keys to navigate rows while the grid is in edit mode. I was able to achieve this using the Keydown event of the RadnumericTextBox, but the edited value seems to revert back to the original value when user press the navigation keys. We are using Batchedit mode so I would like to get to get the red mark on the edited row before it changes the focus to the next row. Could this be achieved? Below is the Javascript I'm calling in the Keydown event of RadnumericTextBox.

function OnKeyDown(sender, args) {

var key = args.keyCode;

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

var data = grid.get_batchEditingManager().get_currentlyEditedCell();

var tableView = grid.get_masterTableView();

if (key == 38) { //Up Key

var row = grid.get_batchEditingManager().get_currentlyEditedRow();

if (row.previousSibling) {

grid.get_batchEditingManager().openRowForEdit(row.previousSibling);

}

else if (key == 40) { //Down key

var row = grid.get_batchEditingManager().get_currentlyEditedRow();

if (row.nextSibling) {

grid.get_batchEditingManager().openRowForEdit(row.nextSibling);

}

HTMLChart Label display NaN (not a number)

I have a chart that is getting data from a SQL database in codebehind. Everything displays correctly and the series have the correct number on hover.

It is a stacked bar with the Show totals work a round found on this site.

http://www.telerik.com/support/kb/aspnet-ajax/chart-%28html5%29/details/displaying-grand-total-in-stacked-series-labels-and-pie-series-legend

I know the data coming from SQL is a number because I'm casting it to decimal.

The gTotal shows: "TL bbl: NaN"

Any Ideas?

code behind:

Dim daFMChart As New SqlDataAdapter(SQLFM, Conn)
daFMChart.Fill(DTFMChart)

Me.ColumnChart.DataSource = DTFMChart
Me.ColumnChart.DataBind()

The SQL data is this:

DateTime TotalRed TotalWhite gTotal

2016-03-25 20000 3 0.0001

2016-03-24 30000 2601 0.0001

Index of column

Does the IndexOf() method from GridColumnCollection return a zero based index?

What will be returned if the column wasn´t found?

Thanks,

Frank

Remark to: http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/reordering

...

GridColumnCollection cols = grid.MasterTableView.Columns;

GridColumn c = cols.FindByUniqueName(columnName);

if (c != null)

...

FindByUniqueName throws a GridException if the column wasn´t found.

So why testing c for null?

Change YAxis Step on client-side

Hi

Is it possible to change the yAxis step client-side?

something like

chart._chartObject.options.yAxis.step = 2;

just after obtain the data.

function setDataFromService(sender, args) {

//Get the returned data

var newData = args.get_content().d;

if (newData.length > 0) {

chart._chartObject.options.title.text = newData[0].Name;

//step Y AXIS

chart._chartObject.options.yAxis.step = 2;

}

else

chart._chartObject.options.title.text = "";

//Set the new datasource to the RadHtmlChart

chart.set_dataSource(newData);

//Repaint the RadHtmlChart

chart.repaint();

//Avoid raising the OnClientResponseEnded client-side event

//avoid setting the received data as content for the RadXmlHttpPanel

args.set_cancel(true);

if (currentLoadingPanel != null) {

currentLoadingPanel.hide(currentControl);

[Solved] Filter on a column field with a OLAP connection

hi,

I have a pivotgrid connected to an OLAP cube.
I have placed on the columns fields the Year field and I wish to filter this field on a specific year in Code-behind in C #

I browsed the online documentation and the forum but I have not found the proper use for the methods FilterByLabel, FilterByValue, SetFilterIncludes.
I think that the examples provided are suitable for connections to relational databases but not multidimensional.

Could someone tell me how I can implement that kind of filter.

thank you in advance

best regards

Looks really bad when zooming

Hi,

The color picker doesn't looks good when zooming in the browser.

Try zooming to 120% and run your demo:

http://demos.telerik.com/aspnet-ajax/colorpicker/examples/overview/defaultcs.aspx

You need to reload the page after zooming!

The Web colors wraps, and the HSB/HSV tabs also wraps a lot!

Save RadGauge to PDF

I am running asp.net framework 4.0; Windows 10; Telerik UI for ASP.NET AJAX v2015.2.729.40

In a webforms asp.net project, I have created multiple RadGauges in my C# codebehind, using data pulled from a SQL Server database. Now I need to do one or more of the following:

-save the RadGauges to PDF or as an image file (that can later be emailed)--preferably mutiple gauges per file;

-OR email the gauges

-OR print the gauges

If I can do the FIRST option, I can, obviously do the other two...

I have searched and searched for several days to attempt to do this on my own before sending in a request...and I simply cannot seem to work this out. Can someone assist me? Thanks in advance for any assistance!
