Use the following code snippet:
GridViewDateTimeColumn orderDate = this.radGridView1.Columns["OrderDate"] as GridViewDateTimeColumn;
orderDate.Format = DateTimePickerFormat.Custom;
orderDate.CustomFormat = "dd-MM-yyyy";
orderDate.FormatString = "{0:dd-MM-yyyy}";
GridViewDateTimeColumn shippedDate = this.radGridView1.Columns["ShippedDate"] as GridViewDateTimeColumn;
shippedDate.Format = DateTimePickerFormat.Custom;
shippedDate.CustomFormat = "dd-MM-yyyy";
shippedDate.FormatString = "{0:dd-MM-yyyy}";
When the grid is grouped by a column with a specific format, it should be taken in consideration by the group row as well.
Please refer to the sample project and open the Home form. The attached gif file illustrates how to reproduce the error.
Workaround: define the grid relations via code.
Use this XML layout:
this.radGridView1.LoadLayout(@"..\..\..\Layout.xml");
<RadGridView Padding="0, 0, 0, 1" Cursor="Default" TabIndex="49">
<MasterTemplate EnableGrouping = "True" AllowEditRow="False" AllowDeleteRow="False" AllowAddNewRow="False" EnableFiltering="True" AutoExpandGroups="True">

Workaround:
public class CustomGridView : RadGridView
{
protected override GridViewLayoutSerializer CreateGridViewLayoutSerializer(Telerik.WinControls.XmlSerialization.ComponentXmlSerializationInfo info)
{
return new CustomGridViewLayoutSerializer(info);

public override string ThemeClassName

To reproduce:
public RadForm1()
{
InitializeComponent();
string txt = "what follows is test characters (some of) which should cause error: เปลี่ยน UPS ที่ห้อง Truck scale เนื่องจากเมื่อวันพฤหัสที่ 13 มีการออฟเบรกเกอร์ที่ ฺฺB/H แต่ว่า เครื่องคอมพิวเตอร์ที่ T/S ดับ ตัว UPS ไม่ทำงาน ทำให้ข้อมูลขณะนั้นหายไป ";
this.label1.Text = txt; // No error
Font font = this.label1.Font;// new Font("Segoe UI", 9.5f, FontStyle.Regular);
this.radLabel1.Font = font;
this.radLabel1.Text = txt; //GDI error
}
Workaround:
this.radLabel1.UseCompatibleTextRendering = false;
When we have column groups with equal names, the Spread Export is not exporting the groups correctly. This will lead to incorrectly merged cells.
A possible workaround is to assure that all column groups have different strings for their Text property.
Use the following code snippet:
public RadForm1()
{
InitializeComponent();
GridViewDecimalColumn idColumn = new GridViewDecimalColumn("Id");
this.radGridView1.Columns.Add(idColumn);
GridViewTextBoxColumn nameColumn = new GridViewTextBoxColumn("Name");
this.radGridView1.Columns.Add(nameColumn);
GridViewDateTimeColumn dateColumn = new GridViewDateTimeColumn("Date");
dateColumn.FilteringMode = GridViewTimeFilteringMode.Date;
dateColumn.Format = DateTimePickerFormat.Custom;
dateColumn.CustomFormat = "dd/MM/yyyy";
dateColumn.FormatString = "{0:dd/MM/yyyy}";
this.radGridView1.Columns.Add(dateColumn);
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
for (int i = 0; i < 50; i++)
{
this.radGridView1.Rows.Add(i,"Row"+i,DateTime.Now.AddDays(i));
}
this.radGridView1.EnableFiltering = true;
this.radGridView1.ShowHeaderCellButtons = true;
this.radGridView1.ShowFilteringRow = false;
this.radGridView1.FilterExpressionChanged += RadGridView1_FilterExpressionChanged;
}
private void RadGridView1_FilterExpressionChanged(object sender, FilterExpressionChangedEventArgs e)
{
Console.WriteLine(e.FilterExpression);
}
If I use the calendar control then the sequence works:
Click the filter button
Click Available filters
Click Equals
Click the calendar button in the value field
Click on December 10, 2021
But if I do not use the calendar control then it does not work. This sequence produces no results:
Click the filter button
Click Available filters
Click Equals
Click on the day component of the value field
Type in 10
Click OK
Workaround:
private void RadGridView1_CreateCompositeFilterDialog(object sender, GridViewCreateCompositeFilterDialogEventArgs e)
{
e.Dialog = new CustomCompositeDataFilterForm();
}
public class CustomCompositeDataFilterForm : CompositeDataFilterForm
{
protected override void OnClosing(CancelEventArgs e)
{
base.OnClosing(e);
if (GridFilterCellElement.ValidateUserFilter(this.FilterDescriptor))
{
CompositeFilterDescriptor cfd = this.FilterDescriptor as CompositeFilterDescriptor;
if (cfd != null)
{
foreach (FilterDescriptor fd in cfd.FilterDescriptors)
{
TrimTimePart(fd);
}
}
else
{
TrimTimePart(this.FilterDescriptor);
}
}
}
private void TrimTimePart(FilterDescriptor filterDescriptor)
{
CompositeFilterDescriptor cfd = filterDescriptor as CompositeFilterDescriptor;
if (cfd != null)
{
foreach (FilterDescriptor fd in cfd.FilterDescriptors)
{
TrimTimePart(fd);
}
}
else
{
DateTime dateValue = DateTime.MinValue;
if (DateTime.TryParse(filterDescriptor.Value + "", out dateValue))
{
dateValue = dateValue.Date;
filterDescriptor.Value = dateValue;
}
}
}
}
Please run the sample project and follow the steps:
1.Open the attached solution in Visual Studio - I am using VS 2022.Follow the steps:
1.Group by Description.
2. Expand the groups
3. Sort by Id
4. Try expanding the hierarchical level. You will notice that some of the rows disappear.
Please refer to the attached gif file illustrating the steps for replicating the issue.
To reproduce, rebind the grid to a data table on button click and show grid's search row.
public RadForm1()
{
InitializeComponent();
this.radGridView1.AllowSearchRow = true;
}
private void RadButton1_Click()
{
DataTable dt = this.GetData();
this.radGridView1.DataSource = dt;
}
private DataTable GetData()
{
DataTable data = new DataTable();
for (int i = 0; i < 5; i++)
{
data.Columns.Add("Column " + i, typeof(int));
data.Columns.Add("Column " + i + 1, typeof(string));
data.Columns.Add("Column " + i + 2, typeof(string));
}
for (int k = 0; k < 5000; k++)
{
object[] parameters = new object[15];
for (int i = 0; i < 15; i += 3)
{
parameters[i] = k;
parameters[i + 1] = "Text " + i;
parameters[i + 2] = "Text " + i + 1;
}
data.Rows.Add(parameters);
}
return data;
}
There are situations where SelectedRows won't return the number of rows preselected when using Begin/EndUpdate even though it seems like there's a row selected in the UI. By preselected I mean the row that looks selected after the rows has been added. This bug has caused some problems for us because the user tried some action on a row they thought was preselected and it would fail.
One situation I found where this bug can be reproducted is by using SortOrder in combination of Begin/EndUpdate. There are probably more situations but I hope this one will let you find the underlying bug.
The attached project contains a simple form with a RadGridView which will contain a list of persons. The list is populated by this method:
public void PopulateGridView(List<Person> persons)
{
PersonGridView.BeginUpdate();
PersonGridView.DataSource = persons;
PersonGridView.EndUpdate();
PersonGridView.Columns[nameof(Person.LastName)].SortOrder = RadSortOrder.Ascending;
}
There are two buttons: "Step one" and "Step two". The first will mimick a situation where the user search a database for persons and none will be found. By clicking the "Get selected rows" you will see that the SelectedRows will return zero rows which is correct.
But when you afterwards click "Step two" (which will add five rows) it seems like there's one row preselected. I would expect the SelectedRows to return that row but by clicking "Get selected rows" again you will see that the returned rows are zero still. The CurrentRow, however is set to the preselected row as expected.
If you start by clicking "Step two" the SelectedRows actually returns the correct rows. Quite strange :-)
I know this is a very small issue and can be avoided. But as I mentioned there are other situations where this problem occurs and it's quite hard to figure out exactly what causes it.
Thank you for your help.
Best regards

Please run the attached sample project. The row's height in the print document is not adjusted according to the column's width in the print page.
Workaround:
Usually for such cases it is convenient to increase the column's width in order to reduce its height and thus it would be able to fit the print page's height. In addition to adjusting the column's width, feel free to use multi-page printing:
Please use the attached sample project.
Hi There,
This call is only a nice to have, it is not critical at all. It is just a slight annoyance when building the Grid's columns - especially when there are many columns to adjust. My workflow is usually as follow.
Add all the columns needed, then after that I will run through all the columns and want to set the widths. But my speed is broken because I can't tab between the 3 width properties: Width, Min Width, Max Width. I have to click to put focus the the next value.
If possible, please can you correct the tab indexes?
Thank you
Kind Regards
Ben
