Default values are provided for fields with non-string type in insert mode when RadGrid is bound using Model Binding. The reason behind it, is that the Insert item of the RadGrid is being bound similar to the edit Item and values are then provided by the framework.

Please create an option to remove the default values when inserting a new record.

Using Entity Framework Code First and model binding in a RadGrid, in insert row there is a default value for all non-string types that are not nullable.

For example "0" for Int or Decimal, "01/01/0001" for Date, etc...

So we have to make code to clear these values in textboxs or make SQL requests to give a default value to RadComboBoxs linked to a Foreign Key.

This does not happens using a FormView and model binding.
This does not happens using a RadGrid and EntityDataSource .

Please make an option to let all controls blank in insert mode without doing code !

There are two easy solutions:
- set HighlightDeletedRows to false
- use the built-in Save Changes button in the command item

A workaround is attached that allows you to use an external button and highlight deleted rows.
It will cause other changes apart from deletion on a row to be lost, but deleted rows will be sent to the server.

Due to browser restrictions, the print behavior is changed and works identically to the one of IE - a new tab/dialog with the grid is opened whose print command is launched. You can observe the behavior in IE at https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/printing/defaultcs.aspx.

A fix in the codebase of the grid will take time, effort and will have to wait in the queue, which is why this is the official solution.

Hello,

I have Radgrid with editable & non editable columns. I edit a row.

If I click an editable cell, it places the cursor within the editable cell. Its correct.

But if I click a readonly cell, it places the cursor in the first editable cell of the line. If the readonly cell is the last cell of the line and if I click the readonly cell, it places the cursor in the first editable cell. If the grid column width is very large, the grid is scrolled to show the first editable cell, and I loose the data which I am visualizing.

If I click in readonly cell, I want to open all the editable cells of the line, but the page should remain in same place. I don't want to place the cursor in any of the editable cells of the line. 

Example grid:
I have a simple Radgrid with batch mode and edit type row.
I have 3 columns id,name and age.
Id and name columns are editable columns. Age column is non editable column.
If I click on age column which is  non editable , the focus moves to id column, which is the first editable column.
If there many columns in my grid and if I click the last  non editable  column, the grid scrolls to first editable column, and I lose the focus of data which I am seeing.
If I click in  non editable column, I want the grid to remain in same place.

This feature can be added as an option by adding property of grid ForceFocusinEdit.
When ForceFocusinEdit= true, if we click in readonly column, focus moves to first editable column.
When ForceFocusinEdit = false, if we click in readonly column, focus is in clicked cell.

Please refer to Ticket ID: 1168296 for more informations.
Thank you

Repro steps:
- go to the RadClientDataSource binding demo: https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/client-data-source-binding/defaultcs.aspx
- filter a column so there is no data in the grid
- remove the filter
Actual: the pager is gone
Expected: the pager is there

SOLUTION: see the following KB article: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/clientdatasource-binding-after-filtering-so-no-records-are-present-and-removing-the-filter-there-is-no-pager
You can show the pager when the filter command is executed:

function OnCommand(sender, args) {
    if (args.get_commandName() == "Filter") {
        $telerik.$(sender.get_element()).find(".rgPager").show();
    }
}

A fix in the codebase of the grid will take time, effort and will have to wait in the queue, which is why this is the official solution.

Create a FilterControlEmptyMessage property so users can set an empty message in the grid filter textbox, much like the EmptyMessag property of RadTextBoxes.

Ideally make it so this property can be accessed/modified client and server-side.

Forum threads on this topic:
https://www.telerik.com/forums/text-in-filter-box-in-radgrid
https://www.telerik.com/forums/filter-emptymessage

RadGrid GridDateTimeColumnEditor is unable to process data of type TimeSpan if PickerType is set to TimePicker.

As a workaround, a GridTemplateColumn can be used with a TimePicker inside EditTemplate

<telerik:GridTemplateColumn>
	<ItemTemplate>
		<%# Eval("Field") %>
	</ItemTemplate>
	<EditItemTemplate>
		<telerik:RadTimePicker ID="RadTimePicker1" runat="server" SelectedTime='<%# Bind("Field") %>'></telerik:RadTimePicker>
	</EditItemTemplate>
</telerik:GridTemplateColumn>

The behavior described in the following KB should be fixed https://www.telerik.com/support/kb/aspnet-ajax/grid/details/horizontal-scroll-speed-is-slow-with-static-headers

In the meantime, you can use the workarounds from the article, or, if it fits your scenario, move to scrolling horizontally through frozen columns via the Prev/Next buttons the grid can provide. You can find an example of that in the second grid (Navigate through the columns by clicking on the Prev/Next buttons) in the following demo: https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/frozen-columns/defaultcs.aspx

Workaround:
Using the Page_Load event handler, verify which control has initiated the postback as well check whether the Event argument is PageSize.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack && Request.Params["__EVENTTARGET"].StartsWith(RadGrid1.UniqueID))
        {
            // check whether the command was PageSizeChange
            if (Request.Params["__EVENTARGUMENT"].Contains("PageSize;"))
            {
                string[] details = Request.Params["__EVENTARGUMENT"].Split(';');
                GridTableView tableView = FindControl(details[0].Replace("FireCommand:", "")) as GridTableView;
                int newPageSize = int.Parse(details[2]);
                Label1.Text += "TableView Name: " + tableView.Name + ", NewPageSize: " + newPageSize+"<br />";
            }
        }
    }

Please provide the ability to customize the way filtering works when RenderMode=Mobile.

Allows for template filtering, and ColumnHeader filtering similar to Lightweight rendering.

We have a RadGrid, which has a set of columns, lets say C1 to CN.
Some of those columns are invisible and can be made visible with the Columns context menu, your control provides.
Assume a column Ci, that is not visible now.

If there exists a visible column Cx with x > i, your control works as expected. The column spans of the headline are ok.
See GoodCase_Step.jpg

If there is no visible column Cx with x > i and Ci is switched visible, your column spans within the headline become completely invalid.
See BadCase.jpg_Step.jpg

We use Version 2017.3.913.45 of your library.

Thanks for your Support!

Dear developers

I would like to see an easy way to have straight forward navigation / edit / save operations in radgrid the way it works for MS Access grids. When working in MS Access grid the record automatically gets dirty on edit, has an easy cancel by ESC button, and auto-saves without any trouble when moving to the next record. The way it works in MS Access is until 2018 still hard to find in a web-control. I managed to use the batch edit and have a kind of auto save when moving to the next record. but it is a pain because the postback action results in loosing the focus on the field you navigated to. 

Why is it so hard to built what the MS boys (the old guys did great work) already built ages ago. Its about time that our web controls behave like old fashioned windows fat client controls.

Please don't lean behind, thinking that all is fine now. its not, a lot can be improved and made easier to handle and give user better user experience.

When I look at the current NEW / UPDATES for ASP.NET Ajax Controls it make me cry to see that its apparently put aside as FINISHED. Wake up, improve more or give a clear roadmap for future developments. Progress should not loose focus on the Telerik ASP.NET Ajax toolbox because that one is still a major tool for the coming 5-10 years I expect.

When the Grid has  <HeaderContextMenu> in the Markup and there is no explicitly set RenderMode of the Grid, the Grid is rendered in Classic. 
It also happens if there is a reference to the ContextMenu in the code behind.

Reproduction steps: 
<script>    
    function f() {
        //code 
        alert($find("RadGrid1")._renderMode);
        Sys.Application.remove_load(f);
    }
    Sys.Application.add_load(f);
</script>
<telerik:RadGrid ID="RadGrid1" runat="server" >  
    <HeaderContextMenu></HeaderContextMenu>         
</telerik:RadGrid>

Solutions: 
1. Remove the HeaderContextMenu tag

2. Set the RenderMode of the Grid explicitly

If the Chrome browser zoom is different from 100%, it is not possible to reorder the RadGrid columns.

The problem can be reproduced at https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/column-row-resize-reorder/defaultcs.aspx .

Enable filtering, Enable HeaderContextMenu and HeaderContextMenuFilter.

First, filter using the HeaderContextMenu filter (e.g. OrderDate GreaterThanOrEqualTo "someDate" AND OrderDate LessThanOrEqualTo "someOtherDate"

Second, apply a filter on another column using the Header filter only (e.g. Freight GreaterThanOrEqualTo "4")

At this point, the filtering applied by the HeaderContexFilterMenu is now partially removed.

Issue only appears when Header filter and HeaderContextMenu filter are used in combination. They work as expected when used separately.

How is it possible to autofit / autosize a giving column (or all columns) when exporting the contents from RadGrid to xlsx using ExportStructure?

The only option available is Width with a defined value. I was unable to find an autofit / autosize function.

And also add AutoFilter feature...

Please consider to add this features :-)

There are two possible approaches to overcome this issue:
- First approach would be to get a reference to the GridHTMLEditorColumn and add the desired tools in the code behind using the "OnItemCreated" server event handler of RadGrid.
- Second approach would be to use GridTemplateColumn with RadEditor.

I have a RadGrid with around 150 columns and a few hundred rows. Currently, I'm looping over them and setting their widths with the resizeColumn function. Unfortunately, it's triggering a recalculation of the layout every time I call this function, so the total page load time can be in the minutes.

Oddly, much of the time was spent on the line:
e.style.width=e.offsetWidth-d+"px";

Chrome's developer tools helpfully pointed me at Forced Reflow. Apparently, when a width is set, initially no extra work is done. When another width is requested, the previous width may have changed it, so the whole layout gets recalculated.

The feature I'd like to request is a function to set column widths in bulk (accepting anything like an array or a dictionary would be fine) that doesn't trigger this recalculation mid-function.
