c# - How do I get the row of a selected cell in a DataGrid? -

-

this question has answer here:

i have wpf application working on. using datagrid control display fields list various information. cannot find datgridview control in visual studio community toolbox. majority of google searches bring info datagridview, frustrating. use datagridview if find, digress. want able capture current row when user selects cell, can value adjacent cell. having no luck finding out how this. here how create datagrid:

 private void displayfieldlengths(string strflfilename, int32 inttotalrowsize, int[] intfieldlengths)     {         int intdisplaycnt, colcnt = 0;         string strdata = "";           lblflinfo.content = "file: " + strflfilename;         datatable dt = new datatable();         dt.columns.add("field", typeof(string));         dt.columns.add("size", typeof(string));         dt.columns.add(" new size", typeof(string));         dt.columns[0].readonly = true;         dt.columns[1].readonly = true;           (intdisplaycnt = 0; intdisplaycnt < intfieldlengths.length; intdisplaycnt++)         {             strdata = "field" + (intdisplaycnt + 1) + "|" + intfieldlengths[intdisplaycnt].tostring() + "|1";             dt.rows.add(strdata.split('|'));         }          dtgrid.itemssource = dt.defaultview;         lblrowsize.content = "total row length: " + inttotalrowsize;      }

here xaml datagrid.

<datagrid isreadonly="false" name="dtgrid" loaded="gridloaded" currentcellchanged="newfieldsizechanged" horizontalalignment="left" verticalalignment="top" height="365" margin="48,53,0,0" width="272" borderthickness="1" borderbrush="black">         <datagrid.resources>             <style targettype="{x:type datagridcell}">                 <style.triggers>                     <trigger property="datagridcell.isselected" value="true">                         <setter property="background" value="#ff9df3d6" />                         <setter property="foreground" value="#000000" />                     </trigger>                 </style.triggers>             </style>         </datagrid.resources>     </datagrid>

it looks you're using events , code-behind implement want achieve. suggest embrace mvvm paradigm , implement data binding. code no longer in events , code-behind (ie not in view) in view model. example, track row changes bind selecteditem property property in view model. responding row changes becomes trivial putting code in view model property's setter. topic long put answer. best of luck.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
