c# 4.0 - How to Generate CheckBoxes checked inside a DataGridView dynamically in C#? -

-

is a datagrid view that contains a checkbox column. I am generating other columns of DataGridView from a table. It's working fine, but now I'm trying to check some checkboxes using this code, but it's not working. Code 

  String Query = "Group_Info" with information as "SELECT ID, Group_Name +" + Phone_No "; GenerateGridView (dataGridView1, query); Datatable DT = GetTableData ("Select tbl generates group_ID"); Forwarding (Datarao RW in DT.RO) {foreach (DataGridViewRow line in DataGrid View 1.Rao) {DataGridWebCox Box CK = (Datagreat View Markbook Call) (Line Seals [0]. Value); If (convert .toiun 32 (line seals [1]. Value) == convert to iTINT 32 (RW ["GROUP_ID"]) {chk.Value = chk.TrueValue; }}}   
 How can we do this?   
 
 
 May try this:  
  DataGridViewCheckBoxColumn chk = New DataGridViewCheckBoxColumn (); dataGridView1.Columns.Add (mortgage); Chk.HeaderText = "Check Data"; Chk.Name = "chk"; DataGridView1.Rows [2] .cel [3] .Value = true;

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
