  You can construct the collection of columns separately from the grid:

  var grid = new WebGrid(data);
  var columns = new List<WebGridColumn>();
  columns.Add( grid.Column("Somecol", "");
  if(shared == "Y"){
      columns.Add( grid.Column(columnName: "Reply", format: @<a href="~/Reply?EId=@item.Eid">Reply</a>);
  } else {
      columns.Add(grid.Columns(columnName: "Share", format: @<a href="~/Share?Eid=@item.Eid">Share</a>);
  }
  ....

  
  Then

  @grid.GetHtml(columns: grid.Columns(columns.ToArray())

  @grid.GetHtml(
      tableStyle: "table",
      headerStyle: "head",
      alternatingRowStyle: "alt",
      columns: grid.Columns(

  if (item.share == 'Y') {
        grid.Column(columnName:"Share",format:@<a href="~/ShareEvents?EId=@item.Eid">Share</a>);
                  }
      else{
        grid.Column(columnName:"Reply",format:@<a href="~/RepliedEvents?EId=@item.Eid">Reply</a>);
                  } ))

  it is giving all kinds of errors. May be i did not explain where i wanted to use the condition.

  You cannot put the condition in the WebGrid.GetHtml method. You have to construct the columns separately as I showed, then pass the constructed columns into the GetHtml method.

  I don't understand what problem you are running into.  However, in your first post, you wanted to conditionally alter the column name. You can't do that the way you are going about things. You can only change the text in the column based on the condition.

  Column heading is not important, i want to direct users, based on if the post has never been shared, i want to link to the page where they will share once shared, now i want that post to have only reply. So that is why you saw he condition whuch says 

  @if (item.shared == null) . Hope i explained what i am trying to do. It is one field but condition directing to different pages.

  grid.Column("", "", format: @<text>@(item.share == "Y" ? Html.Raw("<a href="~/ShareEvents? EId=@item.Eid">Share</a>") : Html.Raw("<a href="~/RepliedEvents?EId=@item.Eid">Reply</a>")) </text>)

  grid.Column(format: @<text>
                      @if (item.shared == null) {
            <p>Share</p>
                      }
                      else {
                          <p>Reply</p>
                      }
                  </text>),

  instead of <p>Share </p> i want "<a href="~/ShareEvents?EId=@item.Eid">" , what am i doing wrong, would apprecite if you can help

  If you prefer to use the if-else statement try

  grid.Column(format:
      @<text>
          @if (item.shared == null){
              @Html.Raw("<a href='ShareEvents?EId=" + @item.Eid +"'>Share</a>")
          } else {
              <p>Reply</p>
          }
      </text>
  )
