In much of the work we do, we need the user to pick a date-from and date-to.  Currently, this means making two distinct controls and having to write validation to ensure that date 1 must be before date 2.  Many sites, such as hotel booking sites, have a date-period selector as a single control and it would be great to have this available as part of the ASP.NET AJAX suite.  I believe that a date-period-selector tool is available as part of other Telerik control suites, so I was rather hoping that it could make an appearance for us too.  Thanks!

Similar to the RadChart's http://demos.telerik.com/aspnet-ajax/chart/examples/newfeatures/intelligentlabels/defaultcs.aspx For the time being you can implement a custom logic for offsetting y point positions of labels. For example offset every 2nd item label position:
       <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>
		<script>
			function pageLoad() {
				offsetItemLabels();
			}
			function offsetItemLabels() {
				//Find all text elements on the page
				var textElements = document.getElementsByTagName("text");
				var numSeriesItemLabels = 0;
				//Iterate through the text elements
				for (var i = 0; i < textElements.length; i++) {
					var currTextEl = textElements[i];
					//Set the desired string/symbol that represents the series labels
					var SeriesLabelSymbol = "@SL";
					if (currTextEl.textContent.indexOf(SeriesLabelSymbol) != -1) {
						numSeriesItemLabels++;
						var currText = currTextEl.textContent.split(SeriesLabelSymbol);
						//Offset y point for every 2nd item label
						currTextEl.textContent = currText[1];
						if ((numSeriesItemLabels) % 2 == 0) {
							currTextEl.attributes.y.textContent = currTextEl.attributes.y.textContent * 1 + 35;
						}
					}
				}
			}
		</script>

I have an AutoCompleteBox that cuts off the last letter of the default message.

This only happens on load and in Mozilla FireFox.

After the user focuses the AutoCompleteBox and loses focuses the full default message is available.

It seems that this is related to the inability of FireFox to handle the size property of the input elements. On initial load, the input is sized by setting the size property of the input. 

A possible workaround would be calling the internal _updateInputSize method in the OnClientLoad event of the AutoCompleteBox: 

I have found that there is a bug when working with tables in the editor in inline editing mode in Safari on Mac - https://demos.telerik.com/aspnet-ajax/editor/examples/inline-editing/defaultcs.aspx.

In the normal editing mode, you can edit the table properties by right clicking inside the table to get the context menu, then choose table properties, add row etc.

In Inline editing mode, it shows the context menu but when you click on any item it says to select the table. None of the other context menu commands like inserting rows etc work.

I have tested on your demo site and you should be able to simulate it there.

Hidden columns are shown on resize when the static headers and frozen column are used.

Video: https://www.screencast.com/t/4Lwuvbp7


Possible workarounds:

- Hide the column with Visible="False", instead of Display="False"

- Hide the column on the client-side:



    function gridCreated(sender, args) {
        var masterTableView = sender.get_masterTableView();
        columnIndex = masterTableView.getColumnByUniqueName("ShipName").get_element().cellIndex;
        setTimeout(function () {
            masterTableView.hideColumn(columnIndex);
        }, 2);
    }




Steps to reproduse:

            <telerik:RadGrid RenderMode="Lightweight" HeaderStyle-Width="200px"
                AutoGenerateColumns="false"
                ID="RadGrid1"
                OnNeedDataSource="RadGrid1_NeedDataSource"
                Width="100%"
                runat="server">
                <ClientSettings>
                    <Scrolling AllowScroll="True" UseStaticHeaders="true" FrozenColumnsCount="2"></Scrolling>
                </ClientSettings>
                <MasterTableView AutoGenerateColumns="false">
                    <Columns>
                        <telerik:GridBoundColumn DataField="SongID" HeaderText="SongID" FilterControlWidth="50px" HeaderStyle-Width="50px">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="SongTitle" HeaderText="Song Title" FilterControlWidth="200px"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="CollectionName" HeaderText="Collection Name" FilterControlWidth="200px"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn FilterControlWidth="50px" DataField="VersionID" HeaderText="VersionID" Display="false"></telerik:GridBoundColumn>
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>

Code Behind:

    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        (sender as RadGrid).DataSource = GetData();
    }

    private DataTable GetData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("SongID");
        dt.Columns.Add("SongTitle");
        dt.Columns.Add("CollectionName");
        dt.Columns.Add("VersionID");

        for (int i = 0; i < 20; i++)
        {
            dt.Rows.Add(i, i + 1, i + 2, i + 3);
        }

        return dt;
    }

When the server's timezone is set to UTC-2 and timezones with bigger negative offset (e.g.  (UTC-08:00) Pacific Time (US & Canada) and (UTC-07:00) Mountain Time (US & Canada)) the appointments on July 1st at 1:30AM are not rendered.

The popular control will be similar to Kendo UI drawer widget: https://demos.telerik.com/kendo-ui/drawer/index.

When trying to load a light-weight skin from external assembly (other than Telerik.Web.UI.Skins), the path to the files is not resolved correctly, hence no resource is loaded.

The current colors, #0082CC and #FFFFFF that are used for forecolor and backcolor, have 4.14:1 color contrast ratio: https://webaim.org/resources/contrastchecker/?fcolor=FFFFFF&bcolor=0082CC

The minimum required color contrast ratio is 4.5:1 for AA Compliance, and 7:1 for AAA Compliance.

A possible alternative color for the #0082CC blue can be #007CC.

When trying to batch edit cell values of the Grid via e.g., RadEditor (GridHTMLEditorColumn or RadEditor in EditItemTemplate of GridTemplateColumn) the cell value always result to a plain text. 

When building Responsive webpages the Telerik navigation control to use is RadNavigation because it properly resizes when the screen is rotated unlike the RadMenu.  

However RadNavigation doesn't seem to have a way to see my current location within a website which is where the breadcrumb come is.

The addition of breadcrumb integration with RadNavigation would benefit Responsive web designer using the Telerik controls.

In GridTableView.cs, you provide a function
 protected virtual GridTableView CreateTableView() (Line 7828).
This function can be overloaded to return derived classes from GridTableView.

But, this is not overloadable completely. Because you create a GridTableView directly in protected void BuildDetailTablesFromDataSource() (Line 8808), too.
There you would have to call a virtual creator function, too.

This is necessary, because I have a lot of Trouble with your DataBind which I was able to fix with an overload. It is much to hard to make this bug visible for you, I really tried to do so already, but I had to fix this that way, because your GridTableView without my derivation fails in our szenario.

The call stack for that problem, I'd had to fix, is always like:
Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Cannot find column CheckSum.

In that, your DataTableView gets an invalid sort Expression string. Therefore, I overwrote DataBind.

But this is not possible in all cases, if you create GridViewTable() objects on your own.

When exporting to Excel XLSX while there are hidden columns at the end of the columns collection and an unused ColumnGroup, the application throws the exception of: Index was out of range. Must be non-negative and less than the size of the collection

System.ArgumentOutOfRangeException
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

This error seems to happen if there is a GridTemplateColumn that has the Exportable property set to False.

Hi I have a straightforward feature request: I would like to be able to "get" the row/column "filter" values the user has selected server-side. Basically need a public property or some type of getter. Currently on the PivotGrid, the row/column "Filter" "Includes/Excludes" can be "set" programmatically, but user selected values can't be easily gotten.

I would use it in a couple ways: 

1) to display context to the user for the numbers in the grid. (e.g., show the user the active filter values responsible for the numbers they are seeing in the PivotGrid Detail). 

2) I need the filter values to close Ticket 1168787.

A Telerik employee make a nice sample project to do drill-through functionality: https://www.telerik.com/blogs/how-to-implement-drill-down-functionality-in-telerik-s-pivotgrid-for-asp.net-ajax-part-2

But the PivotGrid counts and RadGrid detail data records returned are not in agreement because selected PivotGrid filters aren't applied to the detail returned in the RadGrid. I need to do that. I need to be able to mimic a drill through action into the detail records that make up the data counts. If I click a cell that says "100" (orders, 2018 year included) I need 100 orders returned in the detail. Not 7000 orders (all order years, unfiltered).

In that ticket, I'm trying to mimic the functionality similar to an SSAS "drillthrough action" (like many cube browsers have built in, e.g., RANET OLAP), except here with a regular SQL data source. This way I can drill into the detail records that make up the numbers displayed to the user in the PivotGrid. However, as it stands, the counts and detail will not be congruent until I can get the filter values selected by the user and apply them accordingly to the data set for the detail RadGrid. The BI users expect to be able to drill into the data and I need to provide it.

Thank you,

Tom
