Bug report

When the horizontal scroll of the grid is shown and is configured for RTL, the resize handle is mispositioned. 

Reproduction of the problem

1. Make the grid scrollable and set explicit widths to all columns.

2. Make the grid RTL.

3. Introduce multi-column headers.

4. Notice that the columns cannot be resized due to the disposition of the handler.

5. Dojo for replication:

https://dojo.telerik.com/IZInOVUd

6. Notice that whenever the horizontal scroll is not present, the resize handle is positioned correctly.

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all]

Release 2019.R2.SP.Next

The issue is reproducible when the grid consists only from Multi-header columns, the setDataSource() method has been used and one of the columns is initially hidden.

After setting the new data source, the last header gets hidden. The "display: none;" style has been applied to the "th" HTML element.

Steps to reproduce:

1. Create a grid with multi-header columns only.

2. Hide one column initially.

3. Set a new data source via the setDataSource() method.

4. The last column gets hidden.

Sample Dojo:

https://dojo.telerik.com/AcipENOt

Kendo UI version: 2019.1.220

Scheduled for 2020.R1.SP.next

Following example @ https://docs.telerik.com/kendo-ui/knowledge-base/grid-sort-displayed-columns-menu-items sorts a column menu. When hide column is then clicked, the wrong column is hidden.

This can be seen in your own dojo example linked in the above doc and @ https://dojo.telerik.com/UWuxOseV . Hiding column Ship Name hides Ship Address instead.

This seems to have been introduced in 2019 R2 SP1 version.

While the grid pager is enabled, if set a new datasource of this grid via javascript ( grid.setDataSource(new kendo.data.DataSource(obj)) ), multiple pager numbers wrapper wil be created. And this makes pager layout wrong.

We have a project where we need the infinite scroll, column sorting/filtering, and remote data enabled.  We are having some issues with sort and filter.  For quick reference, I used the grid demo and changed it to reflect our configuration.  The problem is the grid fires the read command twice when we have loaded more than one page of data. No issues when we have only loaded the first page.

https://dojo.telerik.com/UDoREFID

To reproduce:

1.  Open Chrome

2.  Load the page

3. Hit run

4. Open Developer Tool

5. Switch to the Network tab and filter by XHR only  

7. Click ProductName to sort. There is only one AJAX call.

8. Scroll to the bottom so it loads the next page. It made two AJAX calls

Bug report

When the Kendo UI Grid is paged and the Search panel input is focused, the page is automatically switched to the first one.

Reproduction of the problem

1. Navigate to the live demo:

https://demos.telerik.com/kendo-ui/grid/search-panel

2. Change page to 2 (for instance).

3. Focus the Search panel input.

4. The page is changed to the first one.


Expected/desired behavior

When the search panel is empty and only focused, the page should remain the same.

Environment

Hi, 

Here is the dojo to reproduce. In this dojo I've created imitation of data, that coming from server in our case. The main idea is to have a grid with lazy loading - it has 10 groups (page 1) and after scrolling down it loads 10 more groups (page 2) and etc.

 

Issue 1. 

After scrolling down, data from the last group is updated with some data, that is not belongs to it. Please see 'Issue1.png' attached.

Issue 2.

Groups from the first page are duplicated after scrolling down. For example, there is a group named 'C3'. After scrolling down, it is duplicated once again. Please see 'Issue2.png' attached. New groups are placed after these duplications. By the way, as groups from the 1st page are duplicated, there is more than 20 groups is shown, but the counted at the bottom of the grid says that '20 of 137' elements are show.

 

So it would be great, if you could fix that. Or even provide temporary fix for us.

Thank you!

Hi Team,

Kendo grid does not allow all columns to be hidden from column menu as it disables the check box for last column in column menu.

But if we set hidden = true and menu = false properties for column, grid hides that column from grid and column menu, but enables the checkbox to hide all columns from grid leaving it empty. After which we can't get back the columns in grid which isn't valid.

Grid should always allow at least one column to be included in grid/menu.

Please find attached screenshot and below sample link.

https://dojo.telerik.com/EHOgaJUK/2

Thanks,

Jyotika

Dear Sir / Madam,

At grid PDF export, in case of allPages: false --> Actual rows are rendered to multiple pages properly, but all pages are written on the first page.

It works well, if I set "options.pdf.multiPage" to "true", but it is not in API reference.

A solution might be if this variable is fixed to true in grid prototype "saveAsPDF" function:
          "options.multiPage = true;" instead of "options.multiPage = options.multiPage || options.allPages;"

Please see this example: https://dojo.telerik.com/usUnUziL/2

Step 1: press "Export to PDF" --> Result: wrong pdf

Step 2: press "Set multiPage: true"

Step 3: press "Export to PDF" --> Result: good pdf

 

Best Regards,

Szabolcs Tóth

We have few of dynamically created grid controls. I like to change the grid header style for all of them. I found this solution on the forum however there is an issue with this. If I override ".k-grid-header th.k-header" the change effects column filter popup content as well. See this example on dojo: https://dojo.telerik.com/@ssharifi/AvayONaQ all text and drop down texts are also effected.

I just need to override the title text. What style can I set so the title text is bold but not the filter options?

Thanks,

Shawn

When using a grid vith virtual scrolling it is currently not possible to get the current result that is viewed. I wanted to show the user approximatelly where he/she currently, i.e., I wanted to display in the GUI something like "Displaying rows 501-600 of 3211" when the pageSize is 100 and the total number of rows in the Grid is 3211. 

This would be helpful for orientation when using virtual scrolling with a high number of results. 

I have tried grid.dataSource.page() and this one is not currently possible to use. The results will be something like 100,200,300,400,500,600,500,700 sometimes going back a hundred and somtimes going forward 200 when using the scrollbar to scroll downwards.

Please check yourself by just creating a virtual scrolling grid with server side operations. Put the printout in the event handler for "DataBound". Page(), Skip() etc are not possible to use for the inconsistent behavior according to above. 

You help has not been able to find a solution or workaround for this and suggested I ask for this as new functionality.

the Kendo grid does't accept cell value changes when using android mobile phone with the Chrome browser. You can test it on the telerik demo https:demos.telerik.com/aspnet-mvc/grid/editing.

for example change the value of the Unit Price and go to the other cell. you will see that the value will become the original value.

just by touching some where outside the border of the grid the value will change.

When the grid is configured for InCell editing and frozen columns, it is expected the first editable cell to be opened for editing when a new record is added. 

However, when there is not an editable cell in the locked columns, it would not search in the main content. Here is an example:

https://dojo.telerik.com/ucEraQOW

A temporary workaround would be to override the editModel function and check in the second table as well:

Enhancement

Excel files generated by Kendo Excel Export cannot be imported by the MS ODBC Driver. The error reported in this forum thread is: External table is not in expected format.

Current behaviour

If the file is opened and resaved with Excel or if the styles.xml file is replaced with any styles.xml generated by MS Excel, the error does not occur. When compared the styles.xml of Excel does not contain a numberFormat, no other obvious major differences at first glance:

E.g.:

<numFmts count="2">
<numFmt formatCode="#" numFmtId="165" />
<numFmt formatCode="#" numFmtId="166" />
</numFmts>

Expected/desired behavior

If possible, modify the styles.xml template to enable seamless use with OleDB

    When clicking on CheckBox to select a line, the widget check other checkbox (on other column of the same line) inserted from column template.

    I suppose that the selector that the system use is too large.

     

    For information, i created a template for boolean column based on how kendo generate checkbox structure (just de be coherent)

     

    See the code extracted from https://dojo.telerik.com/EqiPIkiV

     

     var checkBoxtemplate = function(boolValue){
       	var checkedStr = '';
        if (boolValue) {
        	checkedStr = 'checked="checked"';
        }
    
            
        return '<input class="k-checkbox" data-role="checkbox" ' + checkedStr + ' type="checkbox"><label class="k-checkbox-label k-no-text smi-checkbox-fordisplay"></label>';
     };
      
    $("#grid").kendoGrid({
      columns: [
        {
          selectable: true, 
          width: '30px'
        },
        { field: "name" },
        { field: "age" },
        { field: "administator", 
          template: function (dataItem) { 
            return checkBoxtemplate(dataItem.administator); 
          }  
        }
      ],
      dataSource: [
        { name: "Jane Doe", age: 30, administator: false },
        { name: "John Doe", age: 33, administator: false },
        { name: "BigBoss Doe", age: 70, administator: true }
      ],
      selectable: true

    Hiding the first column in Grid will show a 2 pixels left border instead one.

    Dojo Sample to replicate the issue: https://dojo.telerik.com/ubaLiYEN

    Steps:

    1. Hide the first column (OrderID) from the Column Menu.

    2. Notice the doubled left-border on the left hand side of the Grid.

    If you configure a Kendo Grid with client-side paging, each time you call setDataSource to update the data source then a new .k-pager-numbers-wrap DIV is added to the page controls. I've replicated the problem in Dojo at https://dojo.telerik.com/UTolOzer by taking a basic client-side paging demo, moving the dataSource configuration into a separate function (with data("kendoGrid").setDataSource), and calling that function 25 times. At the end, the source shows the UL element with the page buttons inside 25 .k-pager-numbers-wrap DIV elements.

    I first noticed this problem because in my own environment, each nested DIV was shifting the page buttons left 1 pixel and overlapping the "previous page" buttons. In my Dojo example, with 25 nested DIVs the page buttons disappear completely.

    I've added the following in my own code as a workaround in the dataBound event of the grid:

                                var trueParent = e.sender.pager.element.find(".k-pager-numbers-wrap").first();
                                e.sender.pager.element.find("ul").appendTo(trueParent);
                                trueParent.find(".k-pager-numbers-wrap").remove();
