Question: How to add Combo Box in a RadGridView Cell?

Requirements:

• The column is a GridViewTextBoxColumn, not GridViewComboBoxColumn.
• Depending on the column type, the column will be populated dynamically with either Combo Box or Text Field.
• Each combo box contains different items.

Sample below using DataGridView:

//DataGridView
            dataGridView1.Columns.Add("Item", "Item");
            dataGridView1.Columns.Add("Value", "Value");
            dataGridView1.Columns.Add("Type", "Type");
            dataGridView1.Columns.Add("Options", "Options");

            list = new List<string[]>();
            list.Add(new string[] { "Result", "DropDown", "Pass,Failed" });
            list.Add(new string[] { "UserId", "Text", "" });
            index = 0;
            foreach (string[] s in list)
            {
                dataGridView1.Rows.Add(s[0], "", s[1], s[2]);
                switch (s[1])
                {
                    case "DropDown":
                        DataGridViewComboBoxCell cmb = new DataGridViewComboBoxCell();
                        var selection = s[2].Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).ToList();
                        cmb.DataSource = selection;
                        this.dataGridView1.Rows[index].Cells[1] = cmb;
                        break;

                    case "Text":
                        this.dataGridView1.Rows[index].Cells[1].Value = "Text Field";
                        break;
                }
                index++;
            }

I am developing log viewer using richtexteditor.

I do input the function whenever adding text on richtexteditor, it shows lastest part on there and cursor is located bottom on the control.

How to do it on richtexteditor.

And if you have more convienient choice to develop log viewer. let me know.

Hi,

with custom taggers is it possibile to manage insentive custom grammar?

thank you

Hi,

I am using a RadGridView to display user values related to each others in multiple ways.

I wish to periodically scan all cells to check the values and then flag them with a red or green cell border.

I keep all the cells status in a Dictionary<point, status> with point being the cell coordinates.

However, Idon't find a way to have all cells with a reference in the dictionary permanently showing the right border depending on its status.

I am using the cell_formatting event, but the border color disappear when cell is not current.

Here is some sample code

 private void gvLignesFacture_CellFormatting(object sender, CellFormattingEventArgs e)
    {
        // On décore la cellule selon son status
        Point cellCoordinates = new(e.CellElement.RowIndex, e.CellElement.ColumnIndex);
        if (DictOfGvCellStatusByCoordinates.TryGetValue(cellCoordinates, out var lookStatus))
        {
            switch (lookStatus)
            {
                case CtrlLook.Default:
                    e.CellElement.Font = GlobalVars.smallRegularFont;
                    e.CellElement.BorderColor = Color.Black;
                    break;

                case CtrlLook.Valid:
                    e.CellElement.Font = GlobalVars.smallBoldFont;
                    e.CellElement.BorderColor = Color.Green;
                    break;

                case CtrlLook.Incorrect:
                    e.CellElement.Font = GlobalVars.smallRegularFont;
                    e.CellElement.BorderColor = Color.Red;
                    break;
            }
        }
   }

How to do  this right ?

Many thanks for your answer

First, thanks for the awesome stuff, getting it going was easy.

However, I'm having a few issues and can't seem to figure out a way around them.  I'm trying to make a JSON tagger.

Here is how I'm defining things:

    Private Shared ReadOnly Keywords As String() = New String() {""""}
    Private Shared ReadOnly Operators As String() = New String() {"{", "}", "[", "]", ":", ","}

Here is an example of the output

The problems I see are:

The second double quote isn't colored like the first one.

The colon isn't colored

The comma after the double quote isn't colored

The closing brace and comma aren't colored

Also, is there a way to highlight the text between characters?  I'd like to highlight the keys and values, and differently from each other if possible.

I'm sure I'm doing it wrong, but haven't been able to figure it out.

Thanks!

I'm trying to insert text at the start of a line in the radSyntaxEditor.  

I haven't found a way to do it, and was attempting to use the following code

Dim cp As CaretPosition = editor.SyntaxEditorElement.CaretPosition
cp.MoveToLineStart()

However, this doesn't appear to move to the start of the current line.

Ultimately, I'd rather not actually move the cursor, I'd like to insert without doing that.  Is that possible?

Hello,

I've been trying to enable drag and drop functionality so that the user can sort the RadNavigationView menu items, and it works when the ItemDragMode property is set to Preview, but does nothing when it's set to Immediate, then there's no drag and drop at all, the functionality seems to be disabled.

c.ViewElement.ItemDragMode = PageViewItemDragMode.Immediate

I'm not sure if I'm doing something wrong, or if this is the intended behaviour (so the immediate mode it's not a supported feature), or if it's just a bug.

Thanks

Hi Telerik support team,

I’m strugling with the Winforms GridView GroupComparer and need some help with it. I’ve seen the topic below:

https://docs.telerik.com/devtools/winforms/controls/gridview/grouping/sorting-group-rows

In my case I’ve a generic comparer in which I want to evaluate which column needs some sorting changes. These are my unitColumns and I have a reference to its list at the moment I create the comparer.

this.radGridView1.MasterTemplate.GroupComparer = new CustomGroupComparer(list);

The problem I walk into is that Telerik creates new CustomGroupComparers by itself (I think for every group?). It also demands an empty constructor. This way I have no option to get to the list that I need.

Is there a workaround for this problem?? For this moment I defined a hardcoded List inside the customComparer but that’s not the way to program it.

It would be nice if the custom comparer was part of the GroupDescriptor.

Regards,

Daniel

I'm trying to unregister a tagger for an radSyntaxEditor.  I've applied a tagger previously and want to change it.  So far, it appears that I'd have to save which tagger was used prior, and then unregister it that way?

Meaning, there's no way (that I could find) to get a list of applied taggers.  All of the methods assume you already know what is applied.

I guess you could create an object of each type of tagger and then check for every possible tagger and then remove it, but...

Basically, what I was expecting was either a way to get a collection of the applied taggers, or be able to call the UnRegisterTaggers without parameters to remove them all, etc.

Any help would be great!
