If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.

Example:

If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.

We recently added row group functionality to our grids and we and our users are very happy with this.

 Only thing that bothers us is the drop functionality on the grouppanel. We an issues to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns.

The drop marker indicated the new column to group will be added in front, but the column is added to the end of the grouped columns.

Forum reference:

This is reproducible in the demo on your site. See also the added video.

.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource

Steps to reproduce:

  • Make any change to the first record, such as modifying the Contact Name.
  • On the second record, Click the "x" under the DELETE column to mark it for delete.
  • Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())
  • Choose to Cancel at the popup prompt.
  • Click "Save changes".
  • Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.

To replicate the problem:

  1. Create RadGrid and bind it a datasource
  2. Set ClientSettings - Selecting - AllowRowSelect to true
  3. Set ClientSettings - EnablePostBackOnRowClick to true
  4. Add a GridEditCommandColumn or a ButtonColumn with Edit/Save/Cancel CommandNames
  5. Enable AJAX for the Grid
  6. Run the application in FireFox

Clicking on the Edit button fires the RowClick event of the Grid instead of Edit/Save/Cancel.

Issue seems to happen with RadGrid with Bootstrap Skin, RenderMode Lightweight when RequireFieldValidator is enabled in combination with Batch Editing.

Unexpected look (Bootstrap skin):

Other skins seems to have it right.

Expected look (Default skin):

I have a Telerik RadGrid, and there is a date column on the grid layout. The date format I am using to display date values is "dd/MM/yyyy". Then, I export that grid data to Excel file with GridExcelExportFormat.Biff type. The problem here is when I open the newly exported Excel file, the date format is changed to "MM/dd/yyyy". 

I want to keep displaying my date format "dd/MM/yyyy" in the Excel file after exporting the grid data.

Assuming the following configuration for RadGrid:

  • RenderMode="Mobile"
  • AllowSorting="true"

Testing using a mobile device (e.g. Chrome in Galaxy Nexus)

Test case 1:

If I click on middle of three dots Icon, then RadGrid opens the options menu

Test case 2:

If I click a bit below of the three dots Icon, then RadGrid does a sort on the column automatically

The problem happens when there is a visible insert row on the grid which gets replaced by an empty row in the exported Excel file. The temp solution is to clear the insert row with the code below and the empty row in the generated excel will be removed.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if(e.CommandName == RadGrid.ExportToExcelCommandName)
    {
        // if there are items in edit mode, clear those
        if(RadGrid1.EditIndexes.Count > 0)
        {
            RadGrid1.EditIndexes.Clear();
            RadGrid1.Rebind();
        }
            
        // if insert item is present, cancel the insert form
        if (RadGrid1.MasterTableView.IsItemInserted)
        {
            RadGrid1.MasterTableView.GetInsertItem().FireCommandEvent("Cancel", "");
        }       
    }
}

We are still experiencing a problem with the RadGrid and JAWS when aria support is enabled. The JAWS form fields dialog (INS+F5) renders all elements of the grid on a single line.

When you have both a Detail Item Template and a Detail Table inside a Grid and then when you show a hidden column using the context menu it only shows for the first row and the grid doesn't display properly.  It also throws the javasecript error "Unable to get property '_getVisibleColumnsCount' of undefined or null reference".

It becomes hard to see the checked checkboxes because of the selected color it has by default matches the select color of the grid

Workaround:

        .RadGrid_BlackMetroTouch .rgSelectedRow .RadCheckBox.RadButton_BlackMetroTouch .rbToggleCheckboxChecked::before,
        .RadGrid_Bootstrap .rgSelectedRow .RadCheckBox.RadButton_Bootstrap .rbToggleCheckboxChecked::before,
        .RadGrid_Metro .rgSelectedRow .RadCheckBox.RadButton_Metro .rbToggleCheckboxChecked::before,
        .RadGrid_MetroTouch .rgSelectedRow .RadCheckBox.RadButton_MetroTouch .rbToggleCheckboxChecked::before {
            color: white;
        }

        .RadGrid_Glow .rgSelectedRow .RadCheckBox.RadButton_Glow .rbToggleCheckboxChecked::before,
        .RadGrid_Office2010Black .rgSelectedRow .RadCheckBox.RadButton_Office2010Black .rbToggleCheckboxChecked::before,
        .RadGrid_Telerik .rgSelectedRow .RadCheckBox.RadButton_Telerik .rbToggleCheckboxChecked::before,
        .RadGrid_WebBlue .rgSelectedRow .RadCheckBox.RadButton_WebBlue .rbToggleCheckboxChecked::before {
            color: black;
        }

Sample to reproduce the behavior and compare the default colors in other states/cases:

        <telerik:RadCheckBox runat="server" ID="rcb1"></telerik:RadCheckBox>
        <br />
        <telerik:RadCheckBox runat="server" ID="rcb2" Checked="true"></telerik:RadCheckBox>
        <telerik:RadSkinManager runat="server" ID="RadSkinManager1" Skin="Bootstrap" ShowChooser="true">
        </telerik:RadSkinManager>
        <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" RenderMode="Lightweight" />
        <asp:CheckBox ID="Checkbox1" Text="some checkbox" runat="server" />
        <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" RenderMode="Lightweight">
            <MasterTableView>
                <Columns>
                    <telerik:GridClientSelectColumn></telerik:GridClientSelectColumn>
                    <telerik:GridTemplateColumn HeaderText="rad check box column">
                        <ItemTemplate>
                            <telerik:RadCheckBox runat="server" ID="RadCheckBox1"></telerik:RadCheckBox>
                            <br />
                            <telerik:RadCheckBox runat="server" ID="RadCheckBox2" Checked="true"></telerik:RadCheckBox>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                </Columns>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
        </telerik:RadGrid>

And a dummy data source that is not a good data source in general, but it will suffice to get this running so one can observe

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