igGrid Hiding and automatic columns width
posted

Hi,

I've just installed new 2012.2 version, but I still have the same problem I had with last version.

I am using different grid objects and, only with this one, I have this strange behavior:

  1. FIRST CASE:
    GridModel gm = new GridModel();
    gm.ID = "grid_id";
    gm.DataSource = // list as queryable
    gm.AutoGenerateColumns = false;
    gm.PrimaryKey = "Id";
    gm.HtmlAttributes = new Dictionary<string, object>() { { "class", "grid" } };
    gm.Width = "100%";

    gm.Columns.Add(new GridColumn("Id", "Id", "number", ""));
    gm.Columns.Add(new GridColumn("Description", "Description", "string", ""));
    ...
    NOTE THAT ALL THE COLUMNS ARE WITHOUT DEFINED WIDTH
    ...
    GridHiding hiding = new GridHiding();
    gm.Features.Add(hiding);

    IT WORKS FINE...



  2. SECOND CASE:
    GridModel gm = new GridModel();
    gm.ID = "grid_id";
    gm.DataSource = // list as queryable
    gm.AutoGenerateColumns = false;
    gm.PrimaryKey = "Id";
    gm.HtmlAttributes = new Dictionary<string, object>() { { "class", "grid" } };
    gm.Width = "100%";

    gm.Columns.Add(new GridColumn("Id", "Id", "number", ""));
    gm.Columns.Add(new GridColumn("Description", "Description", "string", ""));
    ...
    NOTE THAT ALL THE COLUMNS ARE WITHOUT DEFINED WIDTH
    ...
    GridHiding hiding = new GridHiding();
    ColumnHidingSetting hSetId = new ColumnHidingSetting();
    hSetId.ColumnKey = "Id";
    hSetId.AllowHiding = false;
    hSetId.Hidden = true;
    hiding.ColumnSettings.Add(hSetId);
    ...
    HERE I DEFINE ONLY ID COLUMN OR SOME COLUMNS OR ALL THE COLUMNS HIDING PROPERTIES (BEHAVIOR IS THE SAME)
    ...
    gm.Features.Add(hiding);

    THIS IS THE RESULT:

Do you know which can be the problem? In other grids I left out column width during their definition and it works correctly.

Thanks

    Hello Flavio,

    Thank you for posting in our forums.

    I wasn't able to reproduce the behavior with the RTM of 12.2 using your code snippet.

    Are you sure that you haven't any kind of virtualization turned on?

    An isolated sample reproducing the issue will be appreciated.

    Hope hearing from you.
