Hi,
Please refer to 2 attached files...
The 'April 2020' file is correct - The yellow color is shown upon setting a filter (Release 2020.1.113.40)
The 'June 2020' file is incorrect - No color is shown indicating filter is set. (Release 2020.2.512.40)
The code sets FilterDescriptor on the 'A PARTY' column.
There is change in the icon of the filter as well :(
When RadGridView is bound to a collection of 60 000 records the difference in the sorting time between using a ProBindingSource and a DataTable is massive. Changes in any core logic in both internal implementations, RadGridView and ProBindingSource, isn't so easy as it looks. Both products have been for a very long time on the market designed to cover the main scenarios of the target customers groups for which they are developed.
By default, if the rows count is less than 10 000 we use quick sort to order the items in the grid. If there are more items we use Red-Black tree. This is controlled by the UseHybridIndex property.
(radGridView.MasterTemplate.ListSource.CollectionView as GridDataView).UseHybridIndex = false;However, both of algorithms use non-linear data access. If the ProBindingSource is not optimized to get data not linearly, the performance wouldn't be satisfactory.
That is why we have introduced the BypassSort functionality to cover this case after cooperation with the OE developers. Thus, our RadGridView won't perform any logic for sorting and the whole time necessary for sorting will depend on the DataSource itself (ProBindingSource in your case) and how this collection sorts its items: https://docs.telerik.com/devtools/winforms/controls/gridview/sorting/basic-sorting
In the current version of Telerik UI for WinForms suite, the BypassSort property is ignored if the BypassFilter is not set to true as well. Hence, the sorting will be still slow.
Both properties shouldn't affect each other and if a developer wants to improve only the sorting performance, it is expected to enable only the ByPassSort property.
Hi,
Please check the attached sample project.
I think CompositeFilter does not respect CaseSensitive property.
Thanks
Please refer to the attached sample project and follow the steps illustrated in the gif file.
The issue is also reproducible in the Demo application.
Workaround: in the RadDataFilter.Edited event you can use the Expression to filter the grid:
Me.RadGridView1.FilterDescriptors.Expression = Me.RadDataFilter1.Expression
Please follow the instruction in this help article: https://docs.telerik.com/devtools/winforms/controls/spellchecker/spellchecking-radgridview
Then, follow the steps illustrated in the attached gif file.
Steps to reproduce:
1. Bind RadGridView to BindingList
2. Clear the rows collection
3. You can see that SelectedRows.Count =1 although Rows.Count = 0
To workaround:
private void radButton1_Click(object sender, EventArgs e)
{
while (this.pedidos.Count > 0)
{
this.pedidos.RemoveAt(0);
}
int rows = this.radGridView1.Rows.Count;
int srows = this.radGridView1.SelectedRows.Count;
}
Dear Telerik Support Team,
I have a Grid with one level of Hierarchy, I am using also the search row control of Gridview but this control only searches the data in the Parent Grid and not in the child Grid, I am using the version: v.2019.2.618.20 of Telerik controls in the Project. Below is the code snippet which is used in the Project, please let us know how we can search in child grid using the search row of the Gridview.
radgvStockCount.DataSource = dtStockCountHeader
radgvStockCount.MasterTemplate.EnableHierarchyFiltering = True
radgvStockCount.UseScrollbarsInHierarchy = True
radgvStockCount.MasterTemplate.Columns("INVCountHeaderId").IsVisible = False
radgvStockCount.MasterTemplate.Columns("INVCountNo").HeaderText = "Stock Count No"
radgvStockCount.MasterTemplate.Columns("CountryCode").HeaderText = "Country Code"
radgvStockCount.MasterTemplate.Columns("AreaCode").HeaderText = "Area Code"
radgvStockCount.MasterTemplate.Columns("LocationCode").HeaderText = "Location Code"
radgvStockCount.MasterTemplate.Columns("LocationName").HeaderText = "Location Name"
radgvStockCount.MasterTemplate.Columns("CreatedBy").HeaderText = "Opened By"
radgvStockCount.MasterTemplate.Columns("CreatedDate").HeaderText = "Opened Date"
Dim template As New GridViewTemplate()
template.DataSource = dtStockCountBatches
radgvStockCount.Templates.Add(template)
template.Columns("INVCountBatchesId").IsVisible = False
template.Columns("INVCountHeaderId").IsVisible = False
template.Columns("INVCountNo").HeaderText = "Stock Count No"
template.Columns("INVCountBatchesNo").HeaderText = "Stock Count Batch No"
template.Columns("LocationCode").HeaderText = "Location Code"
template.Columns("LocationName").HeaderText = "Location Name"
template.Columns("SupervisorQty").HeaderText = "Supervisor Qty"
template.Columns("CreatedBy").HeaderText = "Batch File Uploaded By"
template.Columns("CreatedDate").HeaderText = "Uploaded Date"
template.AllowAddNewRow = False
template.AllowEditRow = False
template.AllowDeleteRow = False
template.AllowSearchRow = False
template.AllowRowResize = False
template.EnableFiltering = True
template.EnableHierarchyFiltering = True
template.ShowHeaderCellButtons = True
template.ShowGroupedColumns = True
template.EnableHierarchyFiltering = True
template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill
Dim relation As New GridViewRelation(radgvStockCount.MasterTemplate, template)
relation.RelationName = "StockCountBatches"
relation.ParentColumnNames.Add("INVCountHeaderId")
relation.ChildColumnNames.Add("INVCountHeaderId")
radgvStockCount.Relations.Add(relation)
When pressing Enter or Tab in the new row the ParsingDateTime event is fired after the editor is validated. Use attached to reproduce.
private void GridView_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
var editor = gridView.ActiveEditor as RadDateTimeEditor;
var editorElement = editor.EditorElement as RadDateTimeEditorElement;
editorElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime;
var provider = ((FreeFormDateTimeProvider)editorElement.TextBoxElement.Provider);
editorElement.TextBoxElement.Provider = new MyFreeFormDateTimeProvider(provider.Mask, provider.Culture, provider.Owner);
}
class MyFreeFormDateTimeProvider : FreeFormDateTimeProvider
{
public MyFreeFormDateTimeProvider(string mask, CultureInfo culture, RadMaskedEditBoxElement owner) : base(mask, culture, owner)
{
}
public override bool Validate(string stringValue)
{
//do your code here
return base.Validate(stringValue);
}
}
We have upgraded from WinControl UI 2010 to 2019 R2.
we have a lot of non-data bound radgridview that we process our data and add each row manually.
The radgridView.Rows.Add(rowdatacolumn1, rowdatacolumn2, rowdatacolumn3) used to return the row index of the added row. It is now returning -1 .
This is breaking a lot of our code.
Workaround:
Set the MaxDate in the custom provider:
Public Class MyMaskDateTimeProvider
Inherits MaskDateTimeProvider
Public Sub New(mask As String, culture As CultureInfo, owner As RadMaskedEditBoxElement)
MyBase.New(mask, culture, owner)
Me.MaxDate = DateTime.MaxValue
End Sub
End Class
Hi,
I am working with the RadGridView in my c# winform application. I am using the custom font ("Font Awesome 5 Free Solid") for the RadGridView using the "CellFormatting" event to view the icons along with the text. Here i am able to see the proper icons with text but when i open the filter menu to filter out the rows, i am unable to see the icons (icons shown as the box) as in filterbox we don't have any custom font.
I tried to working out the properties of the RadTreeNodeCollection but here we dont have any Custom font property for the same.
i want to show the text as it is in the filterbox along with the text and the icon.
so can you suggest what i can do to view the icons in the filterbox?
Check the attachment for reference.
Workaround:
private void RadGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
if (e.RowInfo is GridViewSearchRowInfo)
{
e.RowInfo = new MySerachRow(e.ViewInfo);
}
}
{
public MySerachRow(GridViewInfo viewInfo) : base(viewInfo)
{
}
public override string GetCellFormattedValue(GridViewRowInfo row, GridViewColumn column)
{
if (row is GridViewSummaryRowInfo)
{
return "";
}
return base.GetCellFormattedValue(row, column);
}
}

RadGridView
NEW
- New property inside GridViewSearchRowInfo: DeferredSearch. Gets or sets a value indicating whether grid will wait until enter key is pressed before it starts a search.
I have implemented this and it is exactly what I want and need, Thank you!
However I thought I might point out that when you tab out it doesn't implement the search, only when you press enter.
And when you press the X to clear the search it clears the text box but not the search. the count of found and the highlighted finds remain
Steps to reproduce:
- Click column header to sort.
- Click button which to export to Excel.
- The rows return to unsorted.
- Scroll down slightly and scroll back up and the sort is restored.
This happens after calling RunExport.
I attached a gif and a sample project.
GridView is not correctly drawn if it's not populated and the theme is set to "TelerikMetro" or "TelerikMetroBlue" (the bottom line is missing).
Steps to reproduce the behavior: create a RadForm, add a RadGridView to it and set the theme to "TelerikMetro" or "TelerikMetroBlue" by using ThemeResolutionService.ApplicationThemeName.
