How to use Eto.Forms TreeGridView

I've been at this for a while now and cannot seem to figure out how to get the Eto.Forms TreeGridView Control to properly render. I'm trying to just add a few GridViewItem's at the moment and I just get a small gray bar at the top:
Here is my code:
List<ITreeGridItem> treeGridItems = new List<ITreeGridItem>();
foreach (var contentType in contentTypes)
{
treeGridItems.Add(new TreeGridItem(contentType.Name));
}
Content = new DocumentPage(new TreeGridView
{
DataStore = new TreeGridItemCollection(treeGridItems)
}, new Padding(20));
I'm not even really sure where to start, I just want to get a tree with text to show for each node at the moment and I can't even do that.

After a bit of trial and error I figured out how to use the tree view:
var treeGridView = new TreeGridView
{
BackgroundColor = Colors.White
};
treeGridView.Columns.Add(new GridColumn
{
HeaderText = "Content Type",
DataCell = new TextBoxCell(0)
});
treeGridView.Columns.Add(new GridColumn
{
HeaderText = "Create",
DataCell = new CustomCell
{
CreateCell = r =>
{
TreeGridItem item = r.Item as TreeGridItem;
ContentTypeTag tag = (ContentTypeTag)item.Tag;
var contentType = _siteManager.CurrentSite.ContentTypes.First(x => x.Name.Equals(tag.ClassName));
void Click(object btnSender, EventArgs btnArgs)
{
//Your Event
}
var button = new LinkButton
{
Style = "primary-link-btn",
Text = $"Create {contentType.Name.ToSentenceCase()}",
Command = new Command(Click)
};
return button;
}
}
});
treeGridView.Columns.Add(new GridColumn
{
HeaderText = "Show All",
DataCell = new CustomCell
{
CreateCell = r =>
{
TreeGridItem item = r.Item as TreeGridItem;
ContentTypeTag tag = (ContentTypeTag)item.Tag;
var contentType = _siteManager.CurrentSite.ContentTypes.First(x => x.Name.Equals(tag.ClassName));
void Click(object btnSender, EventArgs btnArgs)
{
//Your Event
}
var button = new LinkButton
{
Style = "primary-link-btn",
Text = $"Show All {contentType.Name.ToSentenceCase()}",
Command = new Command(Click)
};
return button;
}
}
});
var treeGridItemCollection = new TreeGridItemCollection();
foreach (var contentType in _siteManager.CurrentSite.ContentTypes)
{
var item = new TreeGridItem
{
Values = new string[] { contentType.Name.ToSentenceCase(), "Create", "Show All" },
Tag = new ContentTypeTag
{
ClassName = contentType.Name
}
};
treeGridItemCollection.Add(item);
}
treeGridView.DataStore = treeGridItemCollection;
You create the header columns to start and then create a TreeGridItemCollection and set the datastore to that. The values for each column of the row is set in a string array to the Values property of the TreeGridItem.

How to withdraw ListFollower in listbox?

Using TweetSharp I am counting the list of followers. How can I withdraw it to the ListBox?
Here is the code:
var options = new ListFollowerIdsOfOptions() { ScreenName = "PutinRF" };
do
{
if (cursor != null)
options.Cursor = cursor;
var followersList = ts.ListFollowerIdsOf(options);
//listBox1.Items.AddRange(followersList.ToArray());
cursor = followersList.NextCursor;
} while (cursor != 0);

Try to use DataSource property:
listBox1.DataSource = followersList;
or look at following implementation:
var allIds = new List<long>();
var options = new ListFollowerIdsOfOptions() { ScreenName = "PutinRF" };
var followersIds = ts.ListFollowerIdsOf(options);
while (followersIds.NextCursor != 0)
{
options.Cursor = followersIds.NextCursor;
allIds.AddRange(followersIds);
}
listBox1.DataSource = allIds;

My decision:
var options = new ListFollowerIdsOfOptions { ScreenName = "PutinRF" };
List<long> All_ods = new List<long>();
TwitterCursorList<long> followerIDS = ts.ListFollowerIdsOf(options);
while(followerIDS.NextCursor!=null)
{
options.Cursor = followerIDS.NextCursor;
All_ods.AddRange(followerIDS.ToArray());
//listBox1.Items.Add(All_ods.ToArray());
listBox1.DataSource = All_ods;
label1.Text = "Получено: " + listBox1.Items.Count.ToString();
break;
}

How to add rows to a RadGridView in WinForms using c#

I am trying to add a rows to a RadGridView when a use click a button on the form (ie. "Add".)
When the form load I add columns to the RadGridView and make all of them all ReadOnly except one .
When a user click the "Add" button, I want to add a row to this RadGridView. Basically, a user types a UPC code, then I read data from the database and add new row in a grid view with the item name, item price.
Here is what I did to create the columns
private void Register_Load(object sender, EventArgs e) {
GridViewTextBoxColumn UPC = new GridViewTextBoxColumn();
UPC.Name = "UPC";
UPC.HeaderText = "UPC";
UPC.FieldName = "UPC";
UPC.MaxLength = 50;
UPC.TextAlignment = ContentAlignment.BottomRight;
radGridView1.MasterTemplate.Columns.Add(UPC);
radGridView1.Columns["UPC"].Width = 120;
radGridView1.Columns["UPC"].ReadOnly = true;
GridViewTextBoxColumn ItemName = new GridViewTextBoxColumn();
ItemName.Name = "Item Name";
ItemName.HeaderText = "Item Name";
ItemName.FieldName = "ItemName";
ItemName.MaxLength = 100;
ItemName.TextAlignment = ContentAlignment.BottomRight;
radGridView1.MasterTemplate.Columns.Add(ItemName);
radGridView1.Columns["Item Name"].Width = 210;
radGridView1.Columns["Item Name"].ReadOnly = true;
GridViewDecimalColumn QtyColumn = new GridViewDecimalColumn();
QtyColumn.Name = "Qty";
QtyColumn.HeaderText = "Quantity";
QtyColumn.FieldName = "Qty";
QtyColumn.DecimalPlaces = 1;
radGridView1.MasterTemplate.Columns.Add(QtyColumn);
radGridView1.Columns["Qty"].Width = 75;
GridViewMaskBoxColumn PriceColumn = new GridViewMaskBoxColumn();
PriceColumn.Name = "Unit Price";
PriceColumn.FieldName = "UnitPrice";
PriceColumn.HeaderText = "Unit Price";
PriceColumn.MaskType = MaskType.Numeric;
PriceColumn.Mask = "C";
PriceColumn.TextAlignment = ContentAlignment.BottomRight;
PriceColumn.FormatString = "{0:C}";
PriceColumn.DataType = typeof(decimal);
radGridView1.MasterTemplate.Columns.Add(PriceColumn);
radGridView1.Columns["Unit Price"].Width = 75;
radGridView1.Columns["Unit Price"].ReadOnly = true;
GridViewMaskBoxColumn TotalColumn = new GridViewMaskBoxColumn();
TotalColumn.Name = "Total Price";
TotalColumn.FieldName = "TotalPrice";
TotalColumn.HeaderText = "Total Price";
TotalColumn.MaskType = MaskType.Numeric;
TotalColumn.Mask = "C";
TotalColumn.TextAlignment = ContentAlignment.BottomRight;
TotalColumn.FormatString = "{0:C}";
TotalColumn.DataType = typeof(decimal);
radGridView1.MasterTemplate.Columns.Add(TotalColumn);
radGridView1.Columns["Total Price"].Width = 75;
radGridView1.Columns["Total Price"].ReadOnly = true;
}
To add the row Here is what I am doing "when a user click the 'Add' button)
private void ButtonAdd_Click(object sender, EventArgs e) {
string UPC = InputUPC.Text.Trim();
if (UPC.Length < 3) {
return;
}
string sql = " SELECT p.productName, p.price "
+ " FROM products AS p "
+ " WHERE p.productUPC = #upc ";
var parms = new List<MySqlParameter>();
parms.Add(new MySqlParameter("#upc", UPC));
var db = new dbConnetion();
foreach (var i in db.getData(sql, parms, r =>
new ProductsTable() {
_productName = r["productName"].ToString(),
_price = Convert.ToDouble(r["price"])
}
)
) {
//radGridView1.Rows[0].Cells[0].Value = 4.3;
radGridView1.Rows[0].Cells["UPC"].Value = UPC;
radGridView1.Rows[0].Cells["Item Name"].Value = i._productName;
radGridView1.Rows[0].Cells["Qty"].Value = "1";
radGridView1.Rows[0].Cells["Unit Price"].Value = i._price;
radGridView1.Rows[0].Cells["Total Price"].Value = (Convert.ToDouble(i._price) * Convert.ToInt32(radGridView1.Rows[0].Cells["Qty"].Value)).ToString();
}
}
But the add row is giving me an error
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
How can I correctly add rows to the RadGridView when the "Add" button is clicked.

ButtonAdd_Click is wrong because the foreach is always trying to set row 0, which doesn't exist.
You don't specify what GridView you are using, so I can't give specifics, but typically you should be able to call Rows.Add(...).

Dropdown list bind using jquery

I would like this type of binding in dropdownbox
-Any Bachelor's Degree-
BCA
BCOM
-Any Master's Degree-
MCA
MBA
-Any Degree-
PGCDA

You can achieve using below, This is just example you cam change as your requirement
function OnSuccess(data) {
$('#ddlAccessLevelGroup').empty();
var d = data;
var dropdown = $('#ddlAccessLevelGroup');
var GroupCode = "";
var optGroup;
for (var i = 0; i < d.length; i++) {
if (d[i].GroupCode.toString() != GroupCode) {
optGroup = $("<optgroup style='background-color:#94c0d2' />");
optGroup.attr('label', d[i].GroupCode.toString());
}
GroupCode = d[i].GroupCode.toString();
optGroup.append(
$('<option></option>').val(d[i].AccessLvlId.toString()).html(d[i].AccessLvlName.toString())
);
dropdown.append(optGroup);
}
}
C# Code
public IQueryable<AccessLevel> TestGetAccessLevelData()
{
IQueryable<AccessLevel> AccessLevelGrp = null;
IQueryable<AccessLevel> AccessLevel = from a in unitOfWork.ACCESS_LEVEL_RXRepository.Get()
select new AccessLevel
{
AccessLvlId = a.ACCESS_LVL_ID_RX,
AccessLvlName = a.ACCESS_LVL_NAME,
GroupCode = "Group A"
};
IQueryable<AccessLevel> AccessLevel1 = from a in unitOfWork.ACCESS_LEVEL_RXRepository.Get()
select new AccessLevel
{
AccessLvlId = a.ACCESS_LVL_ID_RX,
AccessLvlName = a.ACCESS_LVL_NAME,
GroupCode = "Group B"
};
var result = AccessLevel.Union(AccessLevel1);
return result.OrderBy(c=> c.GroupCode);
}

EWS - How to search for items [message] between dates?

I found the answer on my own after a long search about date format.
The restrictions has to be defined as this:
// greater or equal to
string dateStart = DateTime.Today.add(-6d);
string dateEnd = DateTime.Today.Add(1d);
PathToUnindexedFieldType dateSentPath = new PathToUnindexedFieldType();
dateSentPath.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsGreaterThanOrEqualToType IsGreaterThanOrEqual = new IsGreaterThanOrEqualToType();
IsGreaterThanOrEqual.Item = dateSentPath;
FieldURIOrConstantType dateConstant = new FieldURIOrConstantType();
ConstantValueType dateConstantValue = new ConstantValueType();
dateConstantValue.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateStart.Year.ToString(), dateStart.Month.ToString(), dateStart.Day.ToString());
dateConstant.Item = dateConstantValue;
IsGreaterThanOrEqual.FieldURIOrConstant = dateConstant;
// less than or equal to
PathToUnindexedFieldType dateSentPath1 = new PathToUnindexedFieldType();
dateSentPath1.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsLessThanOrEqualToType lessThanOrEqualTo = new IsLessThanOrEqualToType();
lessThanOrEqualTo.Item = dateSentPath1;
FieldURIOrConstantType dateConstant1 = new FieldURIOrConstantType();
ConstantValueType dateConstantValue1 = new ConstantValueType();
dateConstantValue1.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateEnd.Year.ToString(), dateEnd.Month.ToString(), dateEnd.Day.ToString());
dateConstant1.Item = dateConstantValue1;
lessThanOrEqualTo.FieldURIOrConstant = dateConstant1;
RestrictionType restriction = new RestrictionType();
AndType andType = new AndType();
andType.Items = new SearchExpressionType[] { lessThanOrEqualTo, IsGreaterThanOrEqual };
restriction.Item = andType;
findItemRequest.Restriction = restriction;
Hope this help someone some day ;-)

In case anyone stumbles upon this in the future, EWS has gotten even more strict about date formatting. The accepted answer formatting works for 2 digit months, but it does not for single digit months.
The formatting that works in all cases is:
DateTime.Today.AddDays(15).ToString("yyyy-MM-ddThh:mm:ssZ")

The restriction also works using the "Sortable date/time pattern".
Datetime.Now.ToString("s")
