Hi,

We are develope commands for arcgis pro sdk 2.2 version.We have developed the "Intermediate distance writing " tool.Tool lines are feature class, distance string is the annotation .But annotation (distance string) when I create new one store annotation correctly in  table but  not shown stable in map. When create a new sometimes when I use zoom in/out (change scale), some annotations or all annotations don not display.When I create a new one sometimes all the annotations appear.  Here is the Pictures and Codes below. How can I solve this problem ? Could this problem be a bug?

Hi,

In future try to put your code inside the syntax highlighter (expand the toolbar, choose more then 'syntax highlighter) to make the code easier to read.

One thing to try is to invalidate the row in the callback both before and after the changes. Place an additional "context.Invalidate(annoFeature);" before the textgraphic and symbol changes in the callback.

At 2.3 creating an editing annotation becomes easier as its more integrated into the edit operation and inspector so you wont need the callback or a chained operation.

Hi,

I've added the line in the code above with the bold font, but nothing has changed. Do I have to add or remove anything in the code ? Can you help me ?Here is code below:

editOperation.Create(this.araMesafeLayer as Layer, values, oid => newFeatureID = oid);
bool opResult = editOperation.Execute();
if (opResult) {

var chainedOp = editOperation.CreateChainedOperation();

chainedOp.Callback(context =>{
QueryFilter qf = new QueryFilter();
qf.WhereClause = BaseFeatureEntity.objectIdFieldName + "=" + newFeatureID.ToString();
cursor = fc.Search(qf, false);
cursor.MoveNext();
if (cursor.Current != null) {

annoFeature = cursor.Current as AnnotationFeature;
context.Invalidate(annoFeature);

if (annoFeature != null) {
var textGraphic = annoFeature.GetGraphic() as CIMTextGraphic;
if (textGraphic != null){
var symbol = textGraphic.Symbol.Symbol;
symbol.SetColor(ColorFactory.Instance.BlackRGB);
var cimTextSymbol = symbol as CIMTextSymbol;
cimTextSymbol.HorizontalAlignment = ArcGIS.Core.CIM.HorizontalAlignment.Center;
cimTextSymbol.VerticalAlignment = ArcGIS.Core.CIM.VerticalAlignment.Center;
cimTextSymbol.SetSize(this.size);
textGraphic.Text = this.mesafe.ToString("0.##");
annoFeature.SetGraphic(textGraphic);
annoFeature.Store();
context.Invalidate(annoFeature);
}
}
}
}, fc);
chainedOp.Execute();
}

I cannot reproduce your issue in either 2.2 or our next release (not yet available) 2.3. The placement of your context.Invalidate statements are correct.

Please work with ESRI tech support to resolve your issue. They will most likely need a copy of your data as well.
