Column resize on automatic updated radgridview issue

Hi,

I have a form with a radGridView (with 4 columns), the radGridView datasource is a datatable which i update every one second.

When i try to resize any column the width is being reset instead of stretching according to the mouse position.

Here is the test application code :

Random rndRandom = new Random();

private void RadForm1_Load(object sender, EventArgs e)
{
radGridView1.AutoGenerateColumns = false;

timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("AAA1", typeof(int));
dt.Columns.Add("AAA2", typeof(int));
dt.Columns.Add("AAA3", typeof(int));
dt.Columns.Add("AAA4", typeof(int));

for (int i = 0; i < 20; i++)
{
DataRow dr = dt.NewRow();

dr["AAA1"] = rndRandom.Next();
dr["AAA2"] = rndRandom.Next();
dr["AAA3"] = rndRandom.Next();
dr["AAA4"] = rndRandom.Next();

dt.Rows.Add(dr);
}

radGridView1.DataSource = dt;
}

Is there anyway to sort this issue?

Html detail row layout help

I am implementing a detail child row in a grid as per the example at in ..\QuickStart\GridView\Hierarchy\TabbedChildViews

I have a simplified view with a single row and two columns, row height 100 and column 1 width 350, column 2 width 600 (excluding the image)

I am looking for some pointers on how to get the height of the row/cell to scroll when the height of the contained content exceeds the row height. Also how to get the cell to correctly wrap the text?

Currently I am getting the row rendered as in the image, which is incorrect. It is not wrapping the text correctly as the characters are vanishing off the right edge of the first cell. Also, the content loaded into the cell is a lot higher than the cell/row height ( in the provided image the cell field has 15+ lines of text) , but the scroll bar does not allow scrolling for the entire content. How could this be achieved?

The Cells are added to the view as :

viewDef.RowTemplate.Rows(0).Cells.Add(New CellDefinition(column.FieldName, 0, 1, 1))

And the CellFormatting code for the cell is :

e.CellElement.Text = ("<html>" + e.CellElement.RowInfo.Cells(columnSpec.FieldName).Value.ToString().Replace(" ", " ") + "</html>")
e.CellElement.TextAlignment = ContentAlignment.TopLeft
e.CellElement.Padding = New Padding(3)
e.CellElement.TextWrap = True
e.CellElement.AutoSizeMode = RadAutoSizeMode.Auto
e.CellElement.AutoSize = True

The e.CellElement directives have been added via trial and error.

Thanks,

Mark

using a name instead of a index in ColumnGroups

The following code works:

view.ColumnGroups.Add(new GridViewColumnGroup("AutoPOD"));
view.ColumnGroups.Add(new GridViewColumnGroup("Addresses"));
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());

Is there a way to replace it with something like this, short of using variables:

view.ColumnGroups.Add(new GridViewColumnGroup("AutoPOD"));
view.ColumnGroups.Add(new GridViewColumnGroup("Addresses"));
view.ColumnGroups["autoPOD"].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups["Addresses"].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());

We have a lot of groups and having the name right there would help code readability a lot.

Thanks,

Joe

Change the Parent Summary on SelectedItemChanged

Hi All

I have implemented the gantview in a test winforms application, and I am just wondering if someone can assist me.

On the View, I drag a Task (Child) Item, and thus changes the start or end date.

Now a very Basic need, is that the Summary (Parent) gets updated too.

Here is a toned down version:

void radGanttView1_SelectedItemChanged(object sender, GanttViewSelectedItemChangedEventArgs e)
{
    try
    {
             if (e.Item.End > e.Item.Parent.End)
             {
                    e.Item.Parent.End = e.Item.End;

}

          if (e.Item.Start < e.Item.Parent.Start)
          {
              e.Item.Parent.Start = e.Item.Start;
         }
     }
   catch { }
}

(View1)

Now this "WORKS" in the sense that if I click off the selected child (View2) , and then back on to it, the Summary does update (View3), but I need it to be immediately

Regards

Marius

RadMaskedEditBox literals issue

Hi, I got an issue with the RadMaskedEditBox with standard phone mask (999) 000-0000. It works well when we enter only digits, but when we hit the keys like 123123-1234, the '-' skips the next character so I got text like this "(123) 123-_123". I'm not really familiar with telerik controls and I tried to find some way to avoid this without success. So is there a property or something else to avoid this problem or is there a real issue with the control itself.

Thank you very much.

GridSpreadExport Group column

Hi Support,

I change my export to excel function to be able to have xlsx format instead of xls. So I change my ExportToExcelML to use GridViewSpreadExport function.

Everything works properly except the group column start in column B instead of column A. My users prefer when the data start in column A. You can see the difference between the old and the new format.

Is it possible that the group column start in column A like it was before?

Regards,

Nadia

AutoSuggest, scroll automatically starts at bottom

Hopefully the attached screenshot will show the issue I am having. It is intermittent but when I start typing on a multicolumn within a grid (and I think I have seen this with the stand alone multicolumn as well), the drop down pops but the scroll bar is initialized at the bottom of the list. When this occurs, I am also unable to use my up/down arrow keys to navigate the drop down list so it is quite annoying.

This is on 2016 Q1.

Grouping & GridViewCheckBoxColumns

Hello,

1. I added a grouping expression to my RadGridView, but the GridViewCheckBoxColumns no longer automatically become checked when all of the child rows in each group for that column are checked. How can I regain this functionality?

2. Also, is it possible to add header checkboxes that only apply to the groups? I have my GridViewCheckBoxColumns that apply to the entire column, but what if I just want to check/uncheck all the rows in a particular group?

Thanks!
