问题 In My sample, I make the X axis to rotate to -90. Now the label values are vertical. Some of the values are huge like "Sample Quotes". Due to this huge values, My label area is increased and chart area is decreased. Is it possible to fix the X axis label length in Microsoft chart controls? 回答1: I got the answer for this question. This is possible by MSChart.ChartAreas[0].AxisX.LabelAutoFitStyle = LabelAutoFitStyles.WordWrap; MSChart.ChartAreas[0].AxisX.IsLabelAutoFit = true; Regards, Karthik

问题 I'm using IDataErrorInfo interface to validate my entities. As long as validation logic is reading metadata from attributes, it is the same for all entities, so I've created class public class DataErrorInfo : IDataErrorInfo And all entities are derriving from it. Thing is, that I wish to cache reflection info for derived classes to speed up validation, so every entity type should initialize this cache once per running application. I was thinking to use static readonly field, but found out,

问题 I have a custom handler like this, public class Handler : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; context.Response.Write("Hello World"); } public bool IsReusable { get { return false; } } } Why does this not work? <system.diagnostics> <sources> <source name="System.Web" switchValue="All" propagateActivity="true"> <listeners> <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\logs

问题 I had a nightmare getting this going. Adding the ModalPopupExtender to a form is easy, you drop it on and tell it the two required controls parameters PopupControlID="MyModalPanel" TargetControlID="ButtonToLoadIt" And it just works fine, but is triggered by a client side click of the Target Control. If you want to do some server side code behind??? how to do it ? 回答1: The example code is shown below: HTML CODE: <!-- Hidden Field --> <asp:HiddenField ID="hidForModel" runat="server" /> <asp
