I have a dropdownList that has the following:

DataSource: binds to a table with 2 columns (ID, Style)

DisplayMember: Is Set to "Style"

ValueMember: Is Set to "Style"

I have a binding source which binds to an model. One of its properties, "PartitionStyle" is a string value.

I set the dropdownList DataBinding.Text: BindingSource.PartitionStyle (Note, I did also try DataBinding.SelectedValue as well)

Now when I choose a value from the drop down list, the "PartitionStyle" property updates to that value which is great. So I save that model and close the form down. Now when I relaunch the form passing in that model to the bindingsource, the display or text of that dropdownlist does not have the correct value(has the index 0 value selected).

I've tried setting BindingSource.DataSource to that model, then BindingSource.ResetBindings, it doesn't work. All the rest of the controls that are NOT dropdownList are displaying correctly(textboxes have the correct values from the properties they are binded to, checkboxes as well).

Any help?

Hello,

How can I filter enum from unwished values.

I want to see in the DataEntry list only filtered values, ex. Commercial and Free.  

Hi,

  In RadDateTimePicker the dd/MM/yyyy is not moving as individually but changing on whole. After entering the year it should not go back to date. Video link mentioned below with the issue & how we need it. Please check & share your inputs.

 Grid position is not proper after reload the data. Winforms radgridview we are using.

Grid is having huge data with headers and child grids (Nested grid).

The issue is related to grid position after data save.

User will expand the grid including header ,child and do some edits and save the records.

After save the grid position we are trying to set from code. As a part of the save function grid data will be reloaded and then we are expanding the headers and child grid same as how the user kept.

Below two properties are not consistent before save and after data reload.

 rdGrid.VerticalScroll.Maximum
 rdGrid.VerticalScroll.Minimum

Other than setting these properties how we can set the grid position.  Thanks in Advance

 int position = vScroll.Maximum ;
 bool isMaxValue = position == vScroll.Maximum - vScroll.LargeChange + 1;

     if (isMaxValue)
                            {
                                position = vScroll.Maximum - vScroll.LargeChange + 1;
                            }
                            rdGrid.TableElement.VScrollBar.Value = position;

Hi guys,

So I was following this telerik video on the 3 types of filtering (basic, excel-like, custom) :  https://www.telerik.com/videos/winforms/filtering-and-expressions-in-radgridview-for-winforms

I tried to apply the custom filtering using a textbox just like the video on my project, but I keep getting an error.  It's suppose to search all the rows and match what's in the textbox.  It'll run, but as soon as I try typing into the textbox, I get an error.  What am I doing incorrectly?

I've attached some pics of it and the code as well.  Thank you!

Here is my code:

 private void ProductionInstructionPrintPage_Load(object sender, EventArgs e)
        {
            // TODO: This line of code loads data into the 'dbMTISysDataSet.VW_ProdPrintPage' table. You can move, or remove it, as needed.
            this.vW_ProdPrintPageTableAdapter.Fill(this.dbMTISysDataSet.VW_ProdPrintPage);

            this.WindowState = FormWindowState.Maximized;

            radGridView1.EnableFiltering = true;
            radGridView1.EnableCustomFiltering = true;

        }

private void radTextBox1_TextChanged(object sender, EventArgs e)
        { 

            radGridView1.MasterTemplate.Refresh();
        }

        private void radGridView1_CustomFiltering(object sender, GridViewCustomFilteringEventArgs e)
        {
            // if the custom filter is empty, reset this row to its default state
            if (string.IsNullOrEmpty(radTextBox1.Text))
            {
                e.Visible = true;

                //reset each cell in this row
                for (int i=0; i<radGridView1.ColumnCount; i++)
                {
                    e.Row.Cells[i].Style.Reset();
                    e.Row.InvalidateRow();
                }

                return;
            }

            //if the custom filter is set, locate the cells in this row that match it and colorize them
            e.Visible = false;
            for (int i = 0; i<radGridView1.ColumnCount; i++)
            {
                string text = e.Row.Cells[i].Value.ToString();

                //locate and colorize matching cells
                if (text.IndexOf(radTextBox1.Text, StringComparison.InvariantCultureIgnoreCase) >= 0)
                {
                    e.Row.Cells[i].Style.CustomizeFill = true;
                    e.Row.Cells[i].Style.DrawFill = true;
                    e.Row.Cells[i].Style.BackColor = Color.PowderBlue;
                    e.Visible = true;
                }
                else
                {
                    e.Row.Cells[i].Style.Reset();
                    e.Row.InvalidateRow();
                }
            }
        }

I would like my users to red mark images before sending to us.What I am looking for is where I would have buttons above the image for:

Draw Line
Draw Circle
Draw Rectangle
Draw w/Pen

And each would be preset to width of 2, color red. I do not want to use your Draw Dialogs at all.

I would also want to have Undo/Redo available without using your tool palette.

Save I can handle already since you have the SameImageAs method.

How can I do this please?

Hello Telerik Community , I just moved from devexpress to telerik and I can say it's really amazing for winforms.

I have some questions about licensing to make sure I don't get in trouble for copyright laws.

I'm developing an open-source app which is a 3D modeler and I used Telerik Rad Controls for Winform Trial to build GUI.

So here's the first question , Is it OK if I publish my app source in git-hub when it's using telerik trial version?

And second question , Can I share trial assemblies downloaded from official telerik website ?

In this case users and developers who use my app get nag screen and they need to buy full version of telerik right ?!

So it's OK to do that ?

Regards,

Mike Cell
