disable filtering on a column

[Dario Zanelli]

Hi all,
I have a asp.net page with a Telerik Radgrid control with dynamically generated columns.
I cannot disable the filtering function on a column, even using the AllowFiltering option set to false.
I send you the C# code that generates the columns. There are many columns that are not visible, but editable in the edit form. I don't know whether this can affect the filtering function.
The shown column "Key Control" displays the filter even if I have disabled it. The filter doesn't even work.

this.RadGrid_Processes.MasterTableView.EditMode = GridEditMode.EditForms;

this.RadGrid_Processes.Width = Unit.Pixel(855);

if (controlState.Equals(STATE_NAVIGATING) || controlState.Equals(STATE_LINKING))
{
    this.pnlInstructions.Visible = true;
}
else
{
    this.pnlInstructions.Visible = false;
    this.lblInstructions.Text = "";
}

this.RadGrid_Processes.AllowFilteringByColumn = true;
this.RadGrid_Processes.MasterTableView.AllowFilteringByColumn = true;

boundColumn = new GridBoundColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = "Id";
boundColumn.HeaderText = "Id";
boundColumn.UniqueName = "Id";
boundColumn.Visible = false;
boundColumn.ReadOnly = true;

boundColumn = new GridBoundColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = "Code";
boundColumn.HeaderText = "Code";
boundColumn.SortExpression = "Code";
boundColumn.UniqueName = "Code";
boundColumn.HeaderStyle.Width = Unit.Pixel(90);

boundColumn.CurrentFilterValue = String.Empty;
boundColumn.ShowFilterIcon = false;
boundColumn.CurrentFilterFunction = GridKnownFunction.Contains;
boundColumn.AutoPostBackOnFilter = false;
boundColumn.FilterDelay = 1000;
boundColumn.FilterControlWidth = 80;
boundColumn.AllowFiltering = true;


boundColumn = new GridBoundColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = "Description";
boundColumn.HeaderText = "Description";
boundColumn.SortExpression = "Description";
boundColumn.UniqueName = "Description";
boundColumn.HeaderStyle.Width = Unit.Pixel(650);

boundColumn.CurrentFilterValue = String.Empty;
boundColumn.ShowFilterIcon = false;
boundColumn.CurrentFilterFunction = GridKnownFunction.Contains;
boundColumn.AutoPostBackOnFilter = false;
boundColumn.FilterDelay = 1000;
boundColumn.FilterControlWidth = 600;
boundColumn.AllowFiltering = true;

boundColumn = new GridBoundColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = "TestMode";
boundColumn.HeaderText = "Test Mode";
boundColumn.SortExpression = "TestMode";
boundColumn.UniqueName = "TestMode";
boundColumn.Visible = false;
//boundColumn.AllowFiltering = false;

dropDownColumn = new GridDropDownColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(dropDownColumn);
dropDownColumn.DataField = "FK_ControlType";
dropDownColumn.DataSourceID = this.LinqDataSource_ControlType.ID;
dropDownColumn.ListValueField = "Id";
dropDownColumn.ListTextField = "Description";
dropDownColumn.HeaderText = "Control Type";
dropDownColumn.UniqueName = "Control Type";
dropDownColumn.HeaderStyle.Width = Unit.Pixel(90);
dropDownColumn.EnableEmptyListItem = true;
dropDownColumn.EmptyListItemText = "Select...";
dropDownColumn.Visible = false;
dropDownColumn.EditFormColumnIndex = 1;
//boundColumn.AllowFiltering = false;

dropDownColumn = new GridDropDownColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(dropDownColumn);
dropDownColumn.DataField = "FK_KeyControl";
dropDownColumn.DataSourceID = this.LinqDataSource_YesNo.ID;
dropDownColumn.ListValueField = "Id";
dropDownColumn.ListTextField = "Description";

dropDownColumn.UniqueName = "KeyControl";
dropDownColumn.HeaderStyle.Width = Unit.Pixel(70);
dropDownColumn.EnableEmptyListItem = true;
dropDownColumn.EmptyListItemText = "Select...";
//dropDownColumn.Visible = true;
dropDownColumn.EditFormColumnIndex = 1;
//boundColumn.ShowFilterIcon = false;
boundColumn.AllowFiltering = false;                   

dropDownColumn = new GridDropDownColumn();
this.RadGrid_Processes.MasterTableView.Columns.Add(dropDownColumn);
dropDownColumn.DataField = "FK_Formalized";

this.RadGrid_Processes.MasterTableView.Columns.Add(dropDownColumn);
dropDownColumn.DataField = "FK_ControlFrequency";
dropDownColumn.DataSourceID = this.LinqDataSource_ControlFrequency.ID;
dropDownColumn.ListValueField = "Id";
dropDownColumn.ListTextField = "Description";

dropDownColumn.UniqueName = "ControlFrequency";
dropDownColumn.HeaderStyle.Width = Unit.Pixel(135);
dropDownColumn.EnableEmptyListItem = true;
dropDownColumn.EmptyListItemText = "Select...";
dropDownColumn.Visible = false;
dropDownColumn.EditFormColumnIndex = 1;
//boundColumn.AllowFiltering = false;

this.RadGrid_Processes.MasterTableView.EditFormSettings.ColumnNumber = 2;
this.RadGrid_Processes.MasterTableView.EditFormSettings.EditColumn.ButtonType = GridButtonColumnType.PushButton;

The telerik version I am currently using in Q3 2009 SP1. If it is a bug, is it solved in the newest version?

Thanks in advance.

Best regards,

Hello Dario,

I have tried the same code and it is working on my end (RadControl Version: 2009, 3, 1103, 35). The only mistake that i can see is that you have set " boundColumn.AllowFiltering " as "false" for DropDownColumn( I guess you meant for DropDownColumn). If you do not want filtering for DropDownColumn, then set dropDownColum.AllowFiltering as false.

C#:

GridDropDownColumn dropDownColumn = new GridDropDownColumn();

this.RadGrid1.MasterTableView.Columns.Add(dropDownColumn);

dropDownColumn.DataField = "FirstName";

dropDownColumn.DataSourceID = this.SqlDataSource1.ID;

dropDownColumn.ListValueField = "FirstName";

dropDownColumn.ListTextField = "FirstName";

dropDownColumn.HeaderText = "FirstName";

dropDownColumn.AllowFiltering = false;

Also refer the following documentation which explains the programmatic creation of Grid and grid column.
Programmatic creation

I hope this helps you,
Princy.

Hi Princy!

Thanks for your prompt answer.
Actually I was setting the wrong column with allowfilterning = false.
