Focus filteritem

Hi,

I am using radfilter on a radlistview bound to a datasource. On pageload I use the following code to default show the filteritem Name from the datasource:

if (!IsPostBack)

{

RadFilterTextFieldEditor editor = new RadFilterTextFieldEditor();

RadFilterPartner.FieldEditors.Add(editor);

if (!IsPostBack)

{

editor.FieldName = "NAME";

editor.DataType = typeof(string);

RadFilterContainsFilterExpression filter = new RadFilterContainsFilterExpression("NAME");

filter.Value = "";

RadFilterPartner.RootGroup.Expressions.Add(filter);

}

My question is how I can set the focus on the NAME filteritem on pageload, so the user can start typing the filtertext, instead of manually click the filteritem and then typing the filtertext?

-Kurt

Missing operand after 'NotEqualTo' operator.

In the code below, I get the error: Missing operand after 'NotEqualTo' operator.

if (!Page.IsPostBack)
{
grdGSRComp.MasterTableView.FilterExpression = "([Variance] NotEqualTo \'0\') ";
GridColumn column = grdGSRComp.MasterTableView.GetColumnSafe("Variance");
column.CurrentFilterFunction = GridKnownFunction.NotEqualTo;
column.CurrentFilterValue = "0";
grdGSRComp.MasterTableView.Rebind();
}

This code runs in page_load.

tried different variations and none worked. Any ideas?

Thanks!

Requirements
RadControls version	2008.01.0415.20
.NET version	2
Visual Studio version	2005
programming language	C#

PROJECT DESCRIPTION

This project presents how to add a select/deselect all option for selecting all rows in a grouped Grid by means of a CheckBox residing in the Grid header along with individual group selection.

Disabled sytle on RadComboBox with Parent Skin

I had the same problem others seem to of have. Disabled RadComboBoxes were ugly when used on a page that had a FormDecorator and a parent Skin. Please see the resolution below:

div.RadComboBox_Vista .rcbDisabled INPUT.rcbInput

{

background-color: White !important;

color: Gray !important;

}

Assuming a Skin of 'Vista', this will style the disabled drop down. I made it simple, used the same background color as the table the control was in and choose a Gray fore color.

Hope it helps save someone the few hours it took me to amalgamate a solution.

Default Value For RadCombo In Details View

Hi,

I am trying to set the selected value for a radcombox box in the details view of a radgrid when it is in edit mode. I have been able to do this for the mastertableview by doing the following on the grid's ItemDataBound event.

Private Sub rgvIntranetObjects_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgvIntranetObjects.ItemDataBound

        If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then
            Dim GridItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
            Dim ddlModule As New DropDownList
            Dim ddlType As New DropDownList
            Dim txtModule As New TextBox
            Dim txtType As New TextBox
            ddlType = DirectCast(GridItem.FindControl("ddlObjectType"), DropDownList)
            ddlModule = DirectCast(GridItem.FindControl("ddlObjectModule"), DropDownList)
            txtType = DirectCast(GridItem.FindControl("txtObjectType"), TextBox)
            txtModule = DirectCast(GridItem.FindControl("txtObjectModule"), TextBox)
            ddlModule.SelectedValue = txtModule.Text
            ddlType.SelectedValue = txtType.Text
        End If
End Sub

I think that I need to do the same thing for the DetailsView on the DetailTableDataBind event but I can't figure out the correct syntax for checking if the details view is in edit mode (details view uses in-place editing) or how to get the row so that I can find the controls.

Any help would be appreciated.

Add New Record RadGrid

Hi

I've used the AddNewRecord functionality before and it worked great with a simple 1 GridBoundColumn input appearing. And the Insert/Cancel buttons appearing in the GridEditCommandColumn.

However I'm struggling with using the functionality where the columns are mixed between a GridTemplateColumn and GridBoundColumn. When I click the Add button an input textbox appears under the bound column but not under the template one?

I need it to be the other way around. Does anyone know how to control this? I've tried attaching ColumnEditorID to the template column and not the bound one, but this doesn't make a difference.

Thanks in advance,

Grid
